What Patients Undergoing Gastrointestinal Endoscopic Procedures Should Receive Antibiotic Prophylaxis?
Case
You are asked to admit two patients. The first is a 75-year-old male with a prosthetic aortic valve on warfarin who presents with bright red blood per rectum and is scheduled for colonoscopy. The second patient is a 35-year-old female with biliary obstruction due to choledocholithiasis; she is afebrile with normal vital signs and no leukocytosis. She underwent endoscopic retrograde cholangiopancreatography (ERCP), which did not resolve her biliary obstruction. Should you prescribe prophylactic antibiotics for either patient?
Overview
Providers are often confused regarding which patients undergoing gastrointestinal (GI) endoscopic procedures should receive antibiotic prophylaxis. To answer this question, it is important to understand the goal of prophylactic antibiotics. Are we trying to prevent infective endocarditis or a localized infection?
There are few large, prospective, randomized controlled trials that have examined the need for antibiotic prophylaxis with GI endoscopic procedures. Guidelines from professional societies are mainly based on expert opinion, evidence from retrospective case studies, and meta-analysis reviews.
Review of the Data
Infective endocarditis resulting from GI endoscopy has been a concern of physicians for decades. The American Heart Association (AHA) first published its recommendations for antibiotic prophylaxis of GI tract procedures in 1965. The most recent antibacterial prophylaxis guidelines, published in 2007, have simplified recommendations and greatly scaled back the indications for antibiotics. The new guidelines conclude that frequent bacteremia from daily activities is more likely to precipitate endocarditis than a single dental, GI, or genitourinary tract procedure.1
The American Society for Gastrointestinal Endoscopy (ASGE) reports that 14.2 million colonoscopies, 2.8 million flexible sigmoidoscopies, and nearly as many upper endoscopies are performed in the U.S. each year, but only 15 cases of endocarditis have been reported with a temporal association to a procedure.2
The British Society of Gastroenterology (BSG) found, after reviewing the histories of patients with infective endocarditis from 1983 through 2006, that there is not enough evidence to warrant antibiotic prophylaxis prior to endoscopy. They noted less than one case of endocarditis after GI endoscopy per year as well as significant variation in the time interval between the procedure and symptoms. The BSG also recognized that antibiotic prophylaxis does not always protect against infection and that clinical factors unrelated to the endoscopy may play a significant role in the development of endocarditis.3
Upper GI Endoscopy, Colonoscopy with Biopsy, and Esophageal Dilatation. Administering antibiotics to prevent infective endocarditis is not recommended for patients undergoing routine procedures such as endoscopy with biopsy and colonoscopy with polypectomy. Likewise, patients with a history of prosthetic heart valves, valve repair with prosthetic material, endocarditis, congenital heart disease, or cardiac transplant with valvulopathy do not need prophylactic antibiotics before GI endoscopic procedures. However, for patients who are being treated for an active GI infection, antibiotic coverage for enterococcus may be warranted given the increased risk of developing endocarditis. The AHA acknowledges there are no published studies to support the efficacy of antibiotics to prevent enterococcal endocarditis in patients in this clinical setting.1
Unlike routine endoscopy, esophageal dilation is associated with an increased rate of bacteremia (12%-100%).4 Streptococcus viridans has been found in blood cultures up to 79% of the time after esophageal dilation.5 Patients with malignant strictures have higher rates of bacteremia than those with benign strictures (52.9% versus 15.7%). Patients treated with multiple passes with the esophageal dilator compared to those treated with a single dilation have a higher risk of bacteremia.6 All patients undergoing esophageal stricture dilation should receive pre-procedural prophylactic antibiotics.7
Patients with bleeding esophageal varices also have high rates of bacteremia. Up to 20% of patients with cirrhosis and GI bleeding on admission develop an infection within 48 hours of presentation.8 There is evidence that the bacteremia may actually be related to the variceal bleeding rather than the procedure.9 Patients with bleeding esophageal varices treated with antibiotics have improved outcomes, including a decrease in mortality.10 Therefore, all patients with bleeding esophageal varices should be placed on antibiotic therapy regardless of whether an endoscopic intervention is planned.
Percutaneous Endoscopic Gastrostomy (PEG) Placement. Prophylactic antibiotics are recommended before placement of a PEG. The indication for prophylactic antibiotics is to prevent a gastrostomy site infection, not infective endocarditis. Gastrostomy site infection is unfortunately a fairly common infection, affecting 4% to 30% of patients who undergo PEG tube placement. There is significant evidence that antibiotics are beneficial in preventing peristomal infections. A meta-analysis showed that only eight patients need to be treated with prophylactic antibiotics to prevent a single peristomal infection.11 Since these infections are believed to be caused by contamination from the oropharynx, physicians should consider prophylaxis against pathogens from the oral flora.12
More recently, it has been noted that methicillin-resistant Staphylococcus aureus (MRSA) is increasingly cultured from infection sites.13 In centers with endemic MRSA, patients should be screened and then undergo decontamination prior to the PEG placement in positive cases.
Endoscopic Ultrasound with Fine Needle Aspiration (EUS-FNA). Antibiotic prophylaxis before EUS-FNA of a solid lesion in an organ is generally thought to be unnecessary because the risk of bacteremia with this procedure is low, comparable to routine GI endoscopy with biopsy. The recommendation for prophylactic antibiotics before biopsy of a cystic lesion is different. There is concern that puncturing cystic lesions may create a new infected fluid collection.2 A systematic review of more than 10,000 patients undergoing EUS-FNA with a full range of target organs revealed that, overall, 11.2% of patients experienced a fever and 4.7% of patients had a peri-procedural infection. While it was not possible in this study to determine which patients received prophylactic antibiotics, 93.7% of patients with pancreatic cystic lesions were reported to have been treated with antibiotics.14
A separate, single-center, retrospective trial produced different results. This study examined a population of 253 patients who underwent 266 EUS-FNA of pancreatic cysts and found that prophylactic antibiotics were associated with more adverse events and were not protective for the 3% of the patients with infectious symptoms.15 Despite the conflicting data, guidelines at this time recommend prophylactic antibiotics before drainage of a sterile pancreatic fluid collection that communicates with the pancreatic duct and also for aspiration of cystic lesions along the GI tract and the mediastinum.2
Endoscopic Retrograde Cholangiopancreatography (ERCP). In patients undergoing ERCP, the routine use of prophylactic antibiotics has not been found to be effective in decreasing the risk of post-procedure cholangitis.16 Guidelines recommend the use of prophylactic antibiotics only in those patients in which the ERCP may not completely resolve the biliary obstruction.2 In these patients, the thought is that ERCP can precipitate infection by disturbing bacteria already present in the biliary tree, especially with increased intrabiliary pressure at the time of contrast dye injection.17
Patients with incomplete biliary drainage, including those with primary sclerosing cholangitis (PSC), hilar cholangiocarcinoma, persistent biliary that were not extracted, and strictures that continue to obstruct despite attempted intervention, are thought to be at elevated risk of developing cholangitis post-ERCP. These patients should be placed on prophylactic antibiotics at the time of the procedure to cover biliary flora such as enteric gram negatives and enterococci. Antibiotics should be continued until the biliary obstruction is resolved.2
Additional Populations to Consider. Previously, the International Society for Peritoneal Dialysis recommended that patients on peritoneal dialysis receive prophylactic antibiotics and empty their abdomen of dialysate prior to colonoscopy. This recommendation has been removed from the 2010 guidelines.18 There is also no indication that patients with synthetic vascular grafts or cardiac devices should receive prophylactic antibiotics prior to routine GI endoscopy.19 The American Academy of Orthopaedic Surgeons no longer recommends that patients with joint replacements receive antibiotic prophylaxis prior to GI endoscopy.20
Back to the Case
The older gentleman with a prosthetic valve undergoing colonoscopy should not receive prophylactic antibiotics, because even in the setting of valvulopathy, colonoscopy does not pose a significant risk for infective endocarditis. The young patient with severe choledocholithiasis should be placed on prophylactic antibiotics because she has continued biliary obstruction, which could result in a cholangitis after ERCP.
Bottom Line
Prophylactic antibiotics are not recommended for any patient undergoing routine endoscopy or colonoscopy. They are indicated for patients with bleeding esophageal varices and for patients who undergo esophageal stricture dilation, PEG placement, or pseudocyst or cyst drainage, and those with continued biliary obstruction undergoing ERCP as summarized in Table 1.

Previously, the International Society for Peritoneal Dialysis recommended that patients on peritoneal dialysis receive prophylactic antibiotics and empty their abdomen of dialysate prior to colonoscopy. This recommendation has been removed from the 2010 guidelines.18 There is also no indication that patients with synthetic vascular grafts or cardiac devices should receive prophylactic antibiotics prior to routine GI endoscopy.19 The American Academy of Orthopaedic Surgeons no longer recommends that patients with joint replacements receive antibiotic prophylaxis prior to GI endoscopy.20
Back to the Case
The older gentleman with a prosthetic valve undergoing colonoscopy should not receive prophylactic antibiotics, because even in the setting of valvulopathy, colonoscopy does not pose a significant risk for infective endocarditis. The young patient with severe choledocholithiasis should be placed on prophylactic antibiotics because she has continued biliary obstruction, which could result in a cholangitis after ERCP.
Bottom Line
Prophylactic antibiotics are not recommended for any patient undergoing routine endoscopy or colonoscopy. They are indicated for patients with bleeding esophageal varices and for patients who undergo esophageal stricture dilation, PEG placement, or pseudocyst or cyst drainage, and those with continued biliary obstruction undergoing ERCP as summarized in Table 1.

Problem Solving In Multi-Site Hospital Medicine Groups
Serving as the lead physician for a hospital medicine group (HMG) makes for challenging work. And the challenges and complexity only increase for anyone who serves as the physician leader for multiple practice sites in the same hospital system. In my November 2013 column on multi-site HMG leaders, I listed a few of the tricky issues they face and will mention a few more here.
Large-Small Friction
Unfortunately, tension between hospitalists at the big hospital and doctors at the small, “feeder” hospitals seems pretty common, and I think it’s due largely to high stress and a wide variation in workload, neither of which are in our direct control. At facilities where there is significant tension, I’m impressed by how vigorously the hospitalists at both the small and large hospitals argue that their own site faces the most stress and challenges. (This is a little like the endless debate about who works harder, those who work with residents and those who don’t.)
The hospitalists at the small site point out that they work with little or no subspecialty help and might even have to take night call from home while working during the day. Those at the big hospital say they are the ones with the very large scope of clinical practice and that, rather than making their life easier, the presence of lots of subspecialists makes for additional work coordinating care and communicating with all parties.
Where it exists, this tension is most evident during a transfer from one of the small hospitals to the large one. After all, one of the reasons to form a system of hospitals is so that nearly all patient needs can be met at one of the facilities in the system. Yet, for many reasons, the hospitalists at the large hospital are—sometimes—not as receptive to transfers as might be ideal. They might be short staffed or facing a high census or an unusually high number of admissions from their own ED. Or, perhaps, they’re concerned that the subspecialty services for which the patient is being transferred (e.g. to be scoped by a GI doctor) won’t be as helpful or prompt as needed. Or maybe they’ve felt “burned” by their colleagues at the small hospital for past transfers that didn’t seem necessary.
The result can be that the doctors at the smaller hospital complain that the “mother ship” hospitalists often are unfriendly and unreceptive to transfer requests. Although there may not be a definitive “cure” for this issue, there are several ways to help address the problem.
- In my last column, I mentioned the value of one or more in-person meetings between those who tend to be on the sending and receiving end of transfers, to establish some criteria regarding transfers that are appropriate and review the process of requesting a transfer and making the associated arrangements. In most cases there will be value in the parties meeting routinely—perhaps two to four times annually—to review how the system is working and address any difficulties.
- Periodic social meetings among the hospitalists at each site will help to form relationships that can make it less likely that any conversation about transfers will go in an unhelpful direction. Things can be very different when the people on each end of the phone call know each other personally.
- Record the phone calls between those seeking and accepting/declining each transfer. Scott Rissmiller, MD, the lead hospitalist for the 17 practice sites in Carolinas Healthcare, has said that having underperforming doctors listen to recordings of their phone calls about transfers has, in most cases he’s been involved with, proven to be a very effective way to encourage improvement.
Shared Staffing
The small hospitals in many systems sometimes struggle to find a way to provide economical night coverage. Hospitals below a certain size find it very difficult to justify a separate, in-house night provider. Some hospital systems have had success sharing night staffing, with the large hospital’s night hospitalist, nurse practitioner, or physician assistant providing telephone coverage for “cross cover” issues that arise after hours.
For example, when a nurse at the small hospital needs to contact a night hospitalist, staff will page the provider at the big hospital, and, in many cases, the issue can be managed effectively by phone. This works best when both hospitals are on the same electronic medical record, so that the responding provider can look through the record as needed.
The hospitalist at the small hospital typically stays on back-up call and is contacted if bedside attention is required.
Or, if the large and small hospitals are a short drive apart, the night hospitalist at the large facility might make the short drive to the small hospital when needed. In the case of emergencies (i.e., a code blue), the in-house night ED physician is relied on as the first responder.
Dr. Nelson has been a practicing hospitalist since 1988. He is co-founder and past president of SHM, and principal in Nelson Flores Hospital Medicine Consultants. He is co-director for SHM’s “Best Practices in Managing a Hospital Medicine Program” course. Write to him at [email protected].

Federal Grant Extends Anti-Infection Initiative
The American Hospital Association’s Health Research and Educational Trust (HRET) recently obtained a grant from the federal Agency for Healthcare Research and Quality to expand CUSP, the Comprehensive Unit-based Safety Program for reducing catheter-associated urinary tract infections (CAUTI) and other healthcare-associated infections, to nursing homes and skilled nursing facilities nationwide.
CUSP has posted a 40% reduction in central line-associated bloodstream infections (CLABSI) in 1,000 participating hospitals by providing education and support and an evidence-based protocol. The grant will be administered by HRET in partnership with others, including the University of Michigan Health System, the Association for Professionals in Infection Control and Epidemiology, and SHM.
Meanwhile, a study published in the American Journal of Infection Control found that rates of catheter-associated urinary tract infections in adult patients given urinary catheter placements dropped nationwide to 5.3% in 2010 from 9.4% in 2001.3 The retrospective analysis of data from the National Hospital Discharge Survey found that CAUTI-related mortality and associated length of hospital stay also declined during the same period.

Patient Activation Measure Tool Helps Patients Avoid Hospital Readmissions
–Dr. Hibbard
A recent article in the Journal of Internal Medicine draws a strong link between readmission rates and the degree to which patients are activated—possessing the knowledge, skills, and confidence to manage their own health post-discharge.2 Co-author Judith Hibbard, DrPh, professor of health policy at the University of Oregon, is the lead inventor of the Patient Activation Measure (PAM), an eight-item tool that assigns patients to one of four levels of activation.
In a sample of 700 patients discharged from Boston Medical Center, those with the lowest levels of activation had 1.75 times the risk of 30-day readmissions, more ED visits, and greater utilization of health services, even after adjusting for severity of illness and demographics.
“Contrary to what some may assume, patients who demonstrate a lower level of activation do not fall into any specific racial, economic, or educational demographic,” Dr. Hibbard says, adding that providers should not expect to be able to reliably judge their patients’ ability to self-manage outside of the hospital. “We know that people who measure low tend to have little confidence in their ability to manage their own health. They feel overwhelmed, show poor problem-solving skills, don’t understand what professionals are telling them, and, as a result, may not pay close attention.”
Dr. Hibbard says higher activation scores reflect greater focus on personal health and the effort to monitor it—with more confidence.
The take-home message for hospitalists, she says, is to understand the importance of their patients’ activation level and to tailor interventions accordingly.
“Those with low activation may need more support,” such as post-discharge home visits instead of just a phone call. Low-activation patients should not be overwhelmed with information but should instead be given just a few prioritized key points, combined with the use of reinforcing communications techniques such as teach-back.
“Someone should sit with them and help negotiate their health behaviors,” she adds. “That’s how they get more activated. It doesn’t have to be a doctor going through these things. But just using the clinical lens to understand your patients is not enough.”

Hospitalists Use Online Game to Identify, Manage Sepsis
Teaching trainees to identify and manage sepsis using an online game known as “Septris” earned hospitalists at Stanford University Medical Center in Palo Alto, Calif., a Research, Innovation, and Clinical Vignette category award at HM13.1
“We took third-year medical students and residents in medicine, surgery, and emergency medicine—people who would be sepsis first responders on the floor—and gave them pre- and post-tests that documented improvements in both attitudes and knowledge,” says lead author Lisa Shieh, MD, PhD, Stanford’s medical director of quality in the department of medicine. All participants said they enjoyed playing the game, she reported.
Septris was developed by a multidisciplinary group of physicians, educational technology specialists, and programmers at Stanford. The game offers a case-based interactive learning environment drawn from evidence-based treatment algorithms. Players make treatment decisions and watch as the patient outcome rises or declines. The game’s rapid pace underscores the importance of early diagnosis and treatment.
“We tried to make our game as engaging and real-life as possible,” Dr. Shieh says.
The Stanford team is in touch with the Society of Critical Care Medicine’s Surviving Sepsis Campaign (www.survivingsepsis.org) and with other medical groups internationally. Thousands of players have accessed the game online for free (http://cme.stanford.edu/septris/game/SepsisTetris.html), with a nominal fee for CME credit. It is best played on an iPad or iPhone, Dr. Shieh says.

Teaching trainees to identify and manage sepsis using an online game known as “Septris” earned hospitalists at Stanford University Medical Center in Palo Alto, Calif., a Research, Innovation, and Clinical Vignette category award at HM13.1
“We took third-year medical students and residents in medicine, surgery, and emergency medicine—people who would be sepsis first responders on the floor—and gave them pre- and post-tests that documented improvements in both attitudes and knowledge,” says lead author Lisa Shieh, MD, PhD, Stanford’s medical director of quality in the department of medicine. All participants said they enjoyed playing the game, she reported.
Septris was developed by a multidisciplinary group of physicians, educational technology specialists, and programmers at Stanford. The game offers a case-based interactive learning environment drawn from evidence-based treatment algorithms. Players make treatment decisions and watch as the patient outcome rises or declines. The game’s rapid pace underscores the importance of early diagnosis and treatment.
“We tried to make our game as engaging and real-life as possible,” Dr. Shieh says.
The Stanford team is in touch with the Society of Critical Care Medicine’s Surviving Sepsis Campaign (www.survivingsepsis.org) and with other medical groups internationally. Thousands of players have accessed the game online for free (http://cme.stanford.edu/septris/game/SepsisTetris.html), with a nominal fee for CME credit. It is best played on an iPad or iPhone, Dr. Shieh says.

Should Unaffiliated Physicians Have Infusion Privileges?
“Infusion Privileges” a Simple Answer to Complex Issue
I have a couple of questions based on the following scenario: hospital infusion center treating patients referred by physicians who are not members of hospital staff and don’t have hospital privileges. Since they are not credentialed at the hospital, they cannot give orders for infusion treatment for their patients. And they are not interested in applying for membership and hospital privileges. First, is it OK for the referring physicians to talk to our hospitalist of the day and give an infusion treatment order? Second, what CPT code would the hospitalist use for just writing an infusion treatment order—and can they bill the service?
—Glena Loyola
Dr. Hospitalist responds:
The alternate site infusion therapy market has exploded in the U.S. in the past 25 years. Most of this surge has been driven by increased emphasis on cost containment and the desires of patients to resume their usual lifestyles while recovering from illness. Most recent estimates show that these services represent approximately $9-$11 billion a year. Although the cost is substantial, it is far lower than the cost of inpatient treatment.
Many hospitals have infusion centers, both as revenue-generating ventures and to provide a service for their patients without admitting them to the hospital. Initially, most centers focused on oncologic medications; most now provide a variety of infusion services and therapies. Having clinical staff, prescribing physicians, and pharmacists under the same roof, or in the same healthcare system, should lead to better communication, which is key when administering these specialty drugs. The center at my hospital is of average size, and it seems there are at least one or two medical emergencies there every month. I can imagine the wasted time and lives lost in situations where a full cadre of emergency staff was not immediately available.
The processes and procedures developed by hospital administrators to allow physicians to administer these medications are highly variable. When the centers first came on the scene, most of the prescribing physicians were practicing oncologists and active members of the medical staff. While oncologists still make up the largest group utilizing these centers, rheumatologists, cardiologists, and endocrinologists also are active participants. As these clinicians have aged, and as the services, as well as the variety of infusions, have expanded, hospitals have needed alternate staffing models to keep up.
My CMO created specific “infusion privileges” for health system physicians working on alternate campuses. This privilege allows them to write for the medications but does not give them core privileges like most courtesy staff designations. There is no associated hospital call or ED coverage requirement, and no quality monitoring is needed with this “special” designation. We did consider having our hospitalist write the orders for these docs, but there were many reasons not to go that route—most importantly the logistics and our current HM program’s bandwidth.
The situation you describe, in which physicians call in and give infusion orders to another physician/hospitalist, is the one I believe is most fraught with problems. The potential for prescribing error is very high. Plus, the multiple downstream opportunities for the patient’s care to be compromised are myriad. Because the consequences of a medication error with many of these infusions can be catastrophic, most institutions (including ours) limit who can prescribe them to those specializing in that field. Many also require physicians to use computerized physician order entry, which has been shown to reduce medication errors, for these agents.
The billing requirements for infusion centers and prescribers are very complex and were last globally consolidated in May 2004. CMS annually updates using National Correct Coding Initiative Edits, with which most coders are familiar. The CPT code is tied to the infusion or type of infusion that is given and even incorporates the amount of time it takes to administer. Prior to 2004, the codes incorporated practice expense as well as malpractice relative value units (RVUs), but zero physician RVUs. Since then, a lot has changed. Although a physician can usually bill for services using E&M codes, most require face-to-face time to be allowable. If you would like to bill independently as a prescriber for your services, I recommend you sit down with your coders and decide if it’s feasible.

ICU Pressures Improve Transfers to the Floor
Clinical question: Does ICU strain negatively affect the outcomes of patients transferred to the floor?
Background: With healthcare costs increasing and critical care staff shortages projected, ICUs will have to operate under increasing strain. This may influence decisions on discharging patients from ICUs and could affect patient outcomes.
Study design: Retrospective cohort study.
Setting: One hundred fifty-five ICUs in the United States.
Synopsis: Using the Project IMPACT database, 200,730 adult patients from 107 different hospitals were evaluated in times of ICU strain, determined by the current census, new admissions, and acuity level. Outcomes measured were initial ICU length of stay (LOS), readmission within 72 hours, in-hospital mortality rates, and post-ICU discharge LOS.
Increases of the strain variables from the fifth to the 95th percentiles resulted in a 6.3-hour reduction in ICU LOS, a 2.0-hour decrease in post-ICU discharge LOS, and a 1.0% increase in probability of ICU readmission within 72 hours. Mortality rates during the hospital stay and odds of being discharged home showed no significant change. This study was limited because the ICUs participating were not randomly chosen, outcomes of patients transferred to other hospitals were not measured, and no post-hospital data was collected, so no long-term outcomes could be measured.
Bottom line: ICU bed pressures prompt physicians to allocate ICU resources more efficiently without changing short-term patient outcomes.

Adults Hospitalized for Respiratory Syncytial Virus Infections Have High Morbidity, Mortality Rates
Clinical question: What are the complications and outcomes of respiratory syncytial virus (RSV) infection in adults requiring hospitalization?
Background: RSV is a common cause of lower respiratory tract infection in infants and young children, leading to hospitalization and even death. RSV has been estimated to affect 3%-10% of adults annually, generally causing mild disease. However, the outcomes of adults with more severe disease are not fully known.
Study design: Retrospective cohort study.
Setting: Three acute care, public hospitals in Hong Kong.
Synopsis: All adult patients hospitalized with laboratory-confirmed RSV infection were included during the defined time period. The main outcome measure was all-cause death, with secondary outcome measures of development of acute respiratory failure requiring ventilator support and total duration of hospitalization among survivors. Additionally, the cohort of RSV patients was compared to patients admitted with seasonal influenza during this same time frame. Patients with pandemic 2009 H1N1 infection were not included.
Of patients with RSV, pneumonia was found in 42.3%, bacterial superinfection in 12.5%, and cardiovascular complications in 14.3%. Additionally, 11.1% developed respiratory failure requiring ventilator support. All-cause mortality at 30 days and 60 days was 9.1% and 11.9%, respectively, with pneumonia the most common cause of death. Use of systemic corticosteroids did not improve survival. When the RSV cohort was compared to the influenza cohort, the patients were similar in age, but the RSV patients were more likely to have underlying chronic lung disease and major systemic co-morbidities. The rate of survival and duration of hospitalization were not significantly different.
Bottom line: RSV infection is an underappreciated cause of lower tract respiratory infection in adults; severe infections that require hospitalization have rates of mortality similar to seasonal influenza. Further research on treatment or immunization is needed.

Antibiotic Algorithm Can Guide Therapy in Healthcare-Associated Pneumonia
Clinical question: Can an algorithm based on risk for multidrug-resistant (MDR) organisms and illness severity guide antibiotic selection in healthcare-associated pneumonia (HCAP)?
Background: The 2005 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines identify patients with HCAP as those with recent contact with a healthcare environment, including nursing homes and hemodialysis; however, previous studies have shown that not all patients with healthcare contact have equal risk for MDR organisms.
Study design: Prospective cohort study.
Setting: Japan, multi-center.
Synopsis: Of the 445 enrolled patients, 124 were diagnosed with community-acquired pneumonia (CAP) and 321 with HCAP. Patients with HCAP were classified based on severity of illness or MDR pathogen risk factors (immune suppression, hospitalization within the last 90 days, poor functional status, and antibiotics within the past six months). Patients with low risk (0-1 factors) for MDR organisms were treated for CAP, and patients with high risk (≥2 factors) or moderate risk (≥1 factor) for severe illness were treated for HCAP.
HCAP patients had a higher 30-day mortality rate (13.7% vs. 5.6%, P=0.017), but mortality rate was less in the patients at low risk for MDR pathogens (8.6% vs. 18.2%, P=0.012). Of the HCAP patients, only 7.1% received inappropriate therapy (pathogen resistant to initial antibiotic regimen), and treatment failure was 19.3%.
Appropriateness of initial empiric therapy was determined not to be a mortality risk; however, this trial might be limited by its location, because Japan appears to have fewer MDR pathogens than the U.S.
Bottom line: A treatment algorithm based on risk for MDR organisms and severity of illness can be used to guide empiric antibiotic therapy in patients with HCAP, and, ideally, to reduce excessive use of broad-spectrum antibiotics.

Three-Month Dual Antiplatelet Therapy for Zotarolimus-Eluting Stents
Clinical question: Is short-term, dual antiplatelet therapy noninferior to long-term therapy in zotarolimus-eluting stents?
Background: Current guidelines recommend long-term (>12 months) dual antiplatelet therapy after the placement of drug-eluting stents. The optimal therapy duration in second-generation drug-eluting stents has not been studied; moreover, some studies with multiple drug-eluting stents have suggested no added benefit from long-term therapy.
Study design: Randomized controlled trial.
Setting: Brazil, multi-center.
Synopsis: Researchers randomized 3,211 patients with stable coronary artery disease (CAD) or low-risk acute coronary syndrome (ACS) undergoing intervention with zotarolimus-eluting stents to short-term (three months) or long-term (12 months) dual antiplatelet therapy. Exclusion criteria included ST-elevation myocardial infarction (STEMI), previous drug-eluting stent, scheduled elective surgery within 12 months, or contraindication to aspirin or clopidogrel. Primary endpoints were a composite of death from any cause, MI, stroke, or major bleeding. Secondary endpoints were stent thrombosis, target lesion revascularization, adverse cardiac event, and any bleed.
At one-year follow-up, the short-term group had similar primary (6.0% vs. 5.8%) and secondary (8.3% vs. 7.4%) outcomes compared to the long-term. The short-term group’s noninferiority also was seen in several key subgroups.
This study included patients with stable CAD or low-risk ACS and cannot be generalized to higher-risk patients. Results for zotarolimus-eluting stents cannot be generalized to other second-generation drug-eluting stents.
Bottom line: Zotarolimus-eluting stents, followed by three months of dual antiplatelet therapy, were noninferior to 12 months of therapy in patients with stable CAD or low-risk ACS.
Citation: Feres F, Costa RA, Abizaid A, et al. Three vs. twelve months of dual antiplatelet therapy after zotarolimus-eluting stents: the OPTIMIZE randomized trial. JAMA. 2013;310(23):2510-2522.
De-Escalating Antibiotics in Sepsis
Clinical question: Does tailoring antibiotics based on known pathogens impact mortality for patients with severe sepsis or shock?
Background: In patients with sepsis, the use of early empiric antibiotics reduces morbidity and mortality. De-escalation therapy refers to narrowing the broad-spectrum antibiotics once the pathogen and sensitivities are known; however, no randomized controlled studies have assessed the impact of this therapy on critically ill patients.
Study design: Prospective observational study.
Setting: Academic hospital ICU in Spain.
Synopsis: From January 2008 to May 2012, 628 adult patients were treated empirically with broad-spectrum antibiotics. De-escalation was applied to 219 patients (34.9%). Outcomes measured were ICU mortality, hospital mortality, and 90-day mortality in patients who received de-escalation therapy, patients whose antibiotics were not changed, and patients for whom antibiotics were escalated.
The in-hospital mortality rate was 27.4% in patients who were de-escalated, 32.6% in the unchanged group, and 42.9% in the escalation group. ICU and 90-day mortality were lower in the de-escalation group. De-escalation was more commonly used in medical than in surgical patients.
This study is limited because it is not a randomized controlled study and was single-centered, so it might only be applicable on the larger scale. Also, multi-drug resistant organisms were not evaluated.
Overall, it is safe to narrow empiric antibiotics in severe sepsis and shock when the pathogen and sensitivities are known.
Bottom line: De-escalation of antibiotics in severe sepsis and septic shock is associated with a lower mortality.
Citation: Garnacho-Montero J, Gutierrez-Pizarraya A, Escoresca-Ortega A, et al. De-escalation of empirical therapy is associated with lower mortality in patients with severe sepsis and septic shock. Intensive Care Med. 2014;40(1):32-40.
New Oral Anticoagulants Increase GI Bleed Risk
Clinical question: Do thrombin and factor Xa inhibitors increase the risk of gastrointestinal (GI) bleeding when compared to vitamin K antagonists and heparins?
Background: New oral anticoagulants (thrombin and factor Xa inhibitors) are available and being used with increased frequency due to equal efficacy and ease of administration. Some studies indicate a higher risk of GI bleeding with these agents. Further evaluation is needed, because no reversal therapy is available.
Study design: Systematic review and meta-analysis.
Setting: Data from MEDLINE, Embase, and the Cochrane Library.
Synopsis: More than 150,000 patients from 43 randomized controlled trials were evaluated for risk of GI bleed when treated with new anticoagulants versus traditional therapy. Patients were treated for one of the following: embolism prevention from atrial fibrillation, venous thromboembolism (VTE) prophylaxis post orthopedic surgery, VTE prophylaxis of medical patients, acute VTE, and acute coronary syndrome (ACS). Use of aspirin or NSAIDs was discouraged but not documented. The odds ratio for GI bleeding with use of the new anticoagulants was 1.45, with a number needed to harm of 500. Evaluation of subgroups revealed increased GI bleed risk in patients treated for ACS and acute thrombosis versus prophylaxis. Post-surgical patients had the lowest risk.
This study was limited by the heterogeneity and differing primary outcomes (mostly efficacy rather than safety) of the included trials. Studies excluded high-risk patients, which the authors estimate to be 25%-40% of actual patients. More studies need to be done that include high-risk patients and focus on GI bleed as a primary outcome.
Bottom line: The new anticoagulants tend to have a higher incidence of GI bleed than traditional therapy, but this varies based on indication of therapy and needs further evaluation to clarify risk.

Single vs. Dual Antiplatelet Therapy after Stroke
Clinical question: Is dual antiplatelet therapy more beneficial or harmful than monotherapy after ischemic stroke?
Background: It is recommended that patients with ischemic stroke or transient ischemic attack (TIA) receive lifelong antiplatelet therapy; however, there have been insufficient studies evaluating the long-term safety of dual antiplatelet therapy.
Study design: Meta-analysis of randomized controlled trials (RCTs)
Setting: Data from PubMed, Embase, and the Cochrane Central Register of Controlled Trials.
Synopsis: Data from seven RCTs, including 39,574 patients with recent TIA or ischemic stroke, were reviewed. Comparisons were made regarding occurrence of intracranial hemorrhage (ICH) and recurrent stroke between patients receiving dual antiplatelet therapy and those receiving aspirin or clopidogrel monotherapy. All patients were treated for at least one year.
There was no difference in recurrent stroke or ICH between patients on dual antiplatelet therapy versus aspirin monotherapy. Patients treated with dual antiplatelet therapy did have a 46% increased risk of ICH without any additional protective benefit for recurrent stroke or TIA when compared with patients on clopidogrel monotherapy.
This information should not be applied in the acute setting, given the high risk of stroke after TIA or ischemic stroke. One major limitation of this study was that the individual trials used different combinations of dual antiplatelet therapy.
Bottom line: The risk of recurrent stroke or TIA after dual antiplatelet therapy and after monotherapy with aspirin or clopidogrel is equal, but the risk of ICH compared to clopidogrel monotherapy is increased.
Citation: Lee M, Saver JL, Hong KS, Rao NM, Wu YL, Ovbiagele B. Risk-benefit profile of long-term dual- versus single-antiplatelet therapy among patients with ischemic stroke: a systematic review and meta-analysis. Ann Intern Med. 2013;159(7):463-470.
Endoscopic vs. Surgical Cystogastrostomy for Pancreatic Pseudocyst Drainage
Clinical question: How does endoscopic cystogastrostomy for pancreatic pseudocyst drainage compare to the standard surgical approach?
Background: Pancreatic pseudocysts are a common complication of pancreatitis and necessitate decompression when they are accompanied by pain, infection, or obstruction. Decompression of the pseudocyst can be accomplished using either endoscopic or surgical cystogastrostomy.
Study design: Open-label, single-center, randomized trial.
Setting: Single-center U.S. hospital.
Synopsis: A total of 40 patients were randomly equalized to both treatment arms; 20 patients underwent endoscopic and 20 patients underwent surgical cystogastrostomy. Zero patients in the endoscopic therapy had a pseudocyst recurrence, compared with one patient treated surgically. Length of stay (LOS) and cost were lower for the endoscopic group compared to the surgical group (two days vs. six days, P<0.001, $7,011 vs. $15,052, P=0.003).
This study is limited due to several factors. First, patients with pancreatic necrosis were excluded; had these patients been included, the complication rates and LOS would have been higher. Second, cost difference cannot be generalized across the U.S., because Medicare payments are based on provider types and regions.
Bottom line: Endoscopic cystogastrostomy for pancreatic pseudocyst is equal to the standard surgical therapy and results in decreased LOS and reduced costs.

Long-Term Cognitive Impairment after Critical Illness
Clinical question: Are a longer duration of delirium and higher doses of sedatives associated with cognitive impairment in the hospital?
Background: Survivors of critical illness are at risk for prolonged cognitive dysfunction. Delirium (and factors associated with delirium, namely sedative and analgesic medications) has been implicated in cognitive dysfunction.
Study design: Prospective cohort study.
Setting: Multi-center, academic, and acute care hospitals.
Synopsis: The study examined 821 adults admitted to the ICU with respiratory failure, cardiogenic shock, or septic shock. Patients excluded were those with pre-existing cognitive impairment, those with psychotic disorders, and those for whom follow-up would not be possible. Two risk factors measured were duration of delirium and use of sedative/analgesics. Delirium was assessed at three and 12 months using the CAM-ICU algorithm in the ICU by trained psychology professionals who were unaware of the patients’ in-hospital course.
At three months, 40% of patients had global cognition scores that were 1.5 standard deviations (SD) below population mean (similar to traumatic brain injury), and 26% had scores two SD below population mean (similar to mild Alzheimer’s). At 12 months, 34% had scores similar to traumatic brain injury patients, and 24% had scores similar to mild Alzheimer’s. A longer duration of delirium was associated with worse global cognition at three and 12 months. Use of sedatives/analgesics was not associated with cognitive impairment.
Bottom line: Critically ill patients in the ICU who experience a longer duration of delirium are at risk of long-term cognitive impairments lasting 12 months.

Holding Chambers (Spacers) vs. Nebulizers for Acute Asthma
Clinical question: Are beta-2 agonists as effective when administered through a holding chamber (spacer) as they are when administered by a nebulizer?
Background: During an acute asthma attack, beta-2 agonists must be delivered to the peripheral airways. There has been considerable controversy regarding the use of a spacer compared with a nebulizer. Aside from admission rates and length of stay, factors taken into account include cost, maintenance of nebulizer machines, and infection control (potential of cross-infection via nebulizers).
Study design: Meta-analysis review of randomized controlled trials (RCTs).
Setting: Multi-centered, worldwide studies from community setting and EDs.
Synopsis: In 39 studies of patients with an acute asthma attack (selected from Cochrane Airways Group Specialized Register), the hospital admission rates did not differ on the basis of delivery method in 729 adults (risk ratio=0.94, confidence interval 0.61-1.43) or in 1,897 children (risk ratio=0.71, confidence interval 0.47-1.08). Secondary outcomes included the duration of time in the ED and the duration of hospital admission. Time spent in the ED varied for adults but was shorter for children with spacers (based on three studies). Duration of hospital admission also did not differ when modes of delivery were compared.
Bottom line: Providing beta-2 agonists using nebulizers during an acute asthma attack is not more effective than administration using a spacer.

Outcomes measured were initial ICU length of stay (LOS), readmission within 72 hours, in-hospital mortality rates, and post-ICU discharge LOS.
Increases of the strain variables from the fifth to the 95th percentiles resulted in a 6.3-hour reduction in ICU LOS, a 2.0-hour decrease in post-ICU discharge LOS, and a 1.0% increase in probability of ICU readmission within 72 hours. Mortality rates during the hospital stay and odds of being discharged home showed no significant change. This study was limited because the ICUs participating were not randomly chosen, outcomes of patients transferred to other hospitals were not measured, and no post-hospital data was collected, so no long-term outcomes could be measured.
Bottom line: ICU bed pressures prompt physicians to allocate ICU resources more efficiently without changing short-term patient outcomes.

Adults Hospitalized for Respiratory Syncytial Virus Infections Have High Morbidity, Mortality Rates
Clinical question: What are the complications and outcomes of respiratory syncytial virus (RSV) infection in adults requiring hospitalization?
Background: RSV is a common cause of lower respiratory tract infection in infants and young children, leading to hospitalization and even death. RSV has been estimated to affect 3%-10% of adults annually, generally causing mild disease. However, the outcomes of adults with more severe disease are not fully known.
Study design: Retrospective cohort study.
Setting: Three acute care, public hospitals in Hong Kong.
Synopsis: All adult patients hospitalized with laboratory-confirmed RSV infection were included during the defined time period. The main outcome measure was all-cause death, with secondary outcome measures of development of acute respiratory failure requiring ventilator support and total duration of hospitalization among survivors. Additionally, the cohort of RSV patients was compared to patients admitted with seasonal influenza during this same time frame. Patients with pandemic 2009 H1N1 infection were not included.
Of patients with RSV, pneumonia was found in 42.3%, bacterial superinfection in 12.5%, and cardiovascular complications in 14.3%. Additionally, 11.1% developed respiratory failure requiring ventilator support. All-cause mortality at 30 days and 60 days was 9.1% and 11.9%, respectively, with pneumonia the most common cause of death. Use of systemic corticosteroids did not improve survival. When the RSV cohort was compared to the influenza cohort, the patients were similar in age, but the RSV patients were more likely to have underlying chronic lung disease and major systemic co-morbidities. The rate of survival and duration of hospitalization were not significantly different.
Bottom line: RSV infection is an underappreciated cause of lower tract respiratory infection in adults; severe infections that require hospitalization have rates of mortality similar to seasonal influenza. Further research on treatment or immunization is needed.

Antibiotic Algorithm Can Guide Therapy in Healthcare-Associated Pneumonia
Clinical question: Can an algorithm based on risk for multidrug-resistant (MDR) organisms and illness severity guide antibiotic selection in healthcare-associated pneumonia (HCAP)?
Background: The 2005 American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) guidelines identify patients with HCAP as those with recent contact with a healthcare environment, including nursing homes and hemodialysis; however, previous studies have shown that not all patients with healthcare contact have equal risk for MDR organisms.
Study design: Prospective cohort study.
Setting: Japan, multi-center.
Synopsis: Of the 445 enrolled patients, 124 were diagnosed with community-acquired pneumonia (CAP) and 321 with HCAP. Patients with HCAP were classified based on severity of illness or MDR pathogen risk factors (immune suppression, hospitalization within the last 90 days, poor functional status, and antibiotics within the past six months). Patients with low risk (0-1 factors) for MDR organisms were treated for CAP, and patients with high risk (≥2 factors) or moderate risk (≥1 factor) for severe illness were treated for HCAP.
HCAP patients had a higher 30-day mortality rate (13.7% vs. 5.6%, P=0.017), but mortality rate was less in the patients at low risk for MDR pathogens (8.6% vs. 18.2%, P=0.012). Of the HCAP patients, only 7.1% received inappropriate therapy (pathogen resistant to initial antibiotic regimen), and treatment failure was 19.3%.
Appropriateness of initial empiric therapy was determined not to be a mortality risk; however, this trial might be limited by its location, because Japan appears to have fewer MDR pathogens than the U.S.
Bottom line: A treatment algorithm based on risk for MDR organisms and severity of illness can be used to guide empiric antibiotic therapy in patients with HCAP, and, ideally, to reduce excessive use of broad-spectrum antibiotics.

Three-Month Dual Antiplatelet Therapy for Zotarolimus-Eluting Stents
Clinical question: Is short-term, dual antiplatelet therapy noninferior to long-term therapy in zotarolimus-eluting stents?
Background: Current guidelines recommend long-term (>12 months) dual antiplatelet therapy after the placement of drug-eluting stents. The optimal therapy duration in second-generation drug-eluting stents has not been studied; moreover, some studies with multiple drug-eluting stents have suggested no added benefit from long-term therapy.
Study design: Randomized controlled trial.
Setting: Brazil, multi-center.
Synopsis: Researchers randomized 3,211 patients with stable coronary artery disease (CAD) or low-risk acute coronary syndrome (ACS) undergoing intervention with zotarolimus-eluting stents to short-term (three months) or long-term (12 months) dual antiplatelet therapy. Exclusion criteria included ST-elevation myocardial infarction (STEMI), previous drug-eluting stent, scheduled elective surgery within 12 months, or contraindication to aspirin or clopidogrel. Primary endpoints were a composite of death from any cause, MI, stroke, or major bleeding. Secondary endpoints were stent thrombosis, target lesion revascularization, adverse cardiac event, and any bleed.
At one-year follow-up, the short-term group had similar primary (6.0% vs. 5.8%) and secondary (8.3% vs. 7.4%) outcomes compared to the long-term. The short-term group’s noninferiority also was seen in several key subgroups.
This study included patients with stable CAD or low-risk ACS and cannot be generalized to higher-risk patients. Results for zotarolimus-eluting stents cannot be generalized to other second-generation drug-eluting stents.
Bottom line: Zotarolimus-eluting stents, followed by three months of dual antiplatelet therapy, were noninferior to 12 months of therapy in patients with stable CAD or low-risk ACS.

De-Escalating Antibiotics in Sepsis
Clinical question: Does tailoring antibiotics based on known pathogens impact mortality for patients with severe sepsis or shock?
Background: In patients with sepsis, the use of early empiric antibiotics reduces morbidity and mortality. De-escalation therapy refers to narrowing the broad-spectrum antibiotics once the pathogen and sensitivities are known; however, no randomized controlled studies have assessed the impact of this therapy on critically ill patients.
Study design: Prospective observational study.
Setting: Academic hospital ICU in Spain.
Synopsis: From January 2008 to May 2012, 628 adult patients were treated empirically with broad-spectrum antibiotics. De-escalation was applied to 219 patients (34.9%). Outcomes measured were ICU mortality, hospital mortality, and 90-day mortality in patients who received de-escalation therapy, patients whose antibiotics were not changed, and patients for whom antibiotics were escalated.
The in-hospital mortality rate was 27.4% in patients who were de-escalated, 32.6% in the unchanged group, and 42.9% in the escalation group. ICU and 90-day mortality were lower in the de-escalation group. De-escalation was more commonly used in medical than in surgical patients.
This study is limited because it is not a randomized controlled study and was single-centered, so it might only be applicable on the larger scale. Also, multi-drug resistant organisms were not evaluated.
Overall, it is safe to narrow empiric antibiotics in severe sepsis and shock when the pathogen and sensitivities are known.
Bottom line: De-escalation of antibiotics in severe sepsis and septic shock is associated with a lower mortality.

New Oral Anticoagulants Increase GI Bleed Risk
Clinical question: Do thrombin and factor Xa inhibitors increase the risk of gastrointestinal (GI) bleeding when compared to vitamin K antagonists and heparins?
Background: New oral anticoagulants (thrombin and factor Xa inhibitors) are available and being used with increased frequency due to equal efficacy and ease of administration. Some studies indicate a higher risk of GI bleeding with these agents. Further evaluation is needed, because no reversal therapy is available.
Study design: Systematic review and meta-analysis.
Setting: Data from MEDLINE, Embase, and the Cochrane Library.
Synopsis: More than 150,000 patients from 43 randomized controlled trials were evaluated for risk of GI bleed when treated with new anticoagulants versus traditional therapy. Patients were treated for one of the following: embolism prevention from atrial fibrillation, venous thromboembolism (VTE) prophylaxis post orthopedic surgery, VTE prophylaxis of medical patients, acute VTE, and acute coronary syndrome (ACS). Use of aspirin or NSAIDs was discouraged but not documented. The odds ratio for GI bleeding with use of the new anticoagulants was 1.45, with a number needed to harm of 500. Evaluation of subgroups revealed increased GI bleed risk in patients treated for ACS and acute thrombosis versus prophylaxis. Post-surgical patients had the lowest risk.
This study was limited by the heterogeneity and differing primary outcomes (mostly efficacy rather than safety) of the included trials. Studies excluded high-risk patients, which the authors estimate to be 25%-40% of actual patients. More studies need to be done that include high-risk patients and focus on GI bleed as a primary outcome.
Bottom line: The new anticoagulants tend to have a higher incidence of GI bleed than traditional therapy, but this varies based on indication of therapy and needs further evaluation to clarify risk.

Single vs. Dual Antiplatelet Therapy after Stroke
Clinical question: Is dual antiplatelet therapy more beneficial or harmful than monotherapy after ischemic stroke?
Background: It is recommended that patients with ischemic stroke or transient ischemic attack (TIA) receive lifelong antiplatelet therapy; however, there have been insufficient studies evaluating the long-term safety of dual antiplatelet therapy.
Study design: Meta-analysis of randomized controlled trials (RCTs)
Setting: Data from PubMed, Embase, and the Cochrane Central Register of Controlled Trials.
Synopsis: Data from seven RCTs, including 39,574 patients with recent TIA or ischemic stroke, were reviewed. Comparisons were made regarding occurrence of intracranial hemorrhage (ICH) and recurrent stroke between patients receiving dual antiplatelet therapy and those receiving aspirin or clopidogrel monotherapy. All patients were treated for at least one year.
There was no difference in recurrent stroke or ICH between patients on dual antiplatelet therapy versus aspirin monotherapy. Patients treated with dual antiplatelet therapy did have a 46% increased risk of ICH without any additional protective benefit for recurrent stroke or TIA when compared with patients on clopidogrel monotherapy.
This information should not be applied in the acute setting, given the high risk of stroke after TIA or ischemic stroke. One major limitation of this study was that the individual trials used different combinations of dual antiplatelet therapy.
Bottom line: The risk of recurrent stroke or TIA after dual antiplatelet therapy and after monotherapy with aspirin or clopidogrel is equal, but the risk of ICH compared to clopidogrel monotherapy is increased.

Endoscopic vs. Surgical Cystogastrostomy for Pancreatic Pseudocyst Drainage
Clinical question: How does endoscopic cystogastrostomy for pancreatic pseudocyst drainage compare to the standard surgical approach?
Background: Pancreatic pseudocysts are a common complication of pancreatitis and necessitate decompression when they are accompanied by pain, infection, or obstruction. Decompression of the pseudocyst can be accomplished using either endoscopic or surgical cystogastrostomy.
Study design: Open-label, single-center, randomized trial.
Setting: Single-center U.S. hospital.
Synopsis: A total of 40 patients were randomly equalized to both treatment arms; 20 patients underwent endoscopic and 20 patients underwent surgical cystogastrostomy. Zero patients in the endoscopic therapy had a pseudocyst recurrence, compared with one patient treated surgically. Length of stay (LOS) and cost were lower for the endoscopic group compared to the surgical group (two days vs. six days, P<0.001, $7,011 vs. $15,052, P=0.003).
This study is limited due to several factors. First, patients with pancreatic necrosis were excluded; had these patients been included, the complication rates and LOS would have been higher. Second, cost difference cannot be generalized across the U.S., because Medicare payments are based on provider types and regions.
Bottom line: Endoscopic cystogastrostomy for pancreatic pseudocyst is equal to the standard surgical therapy and results in decreased LOS and reduced costs.

Long-Term Cognitive Impairment after Critical Illness
Clinical question: Are a longer duration of delirium and higher doses of sedatives associated with cognitive impairment in the hospital?
Background: Survivors of critical illness are at risk for prolonged cognitive dysfunction. Delirium (and factors associated with delirium, namely sedative and analgesic medications) has been implicated in cognitive dysfunction.
Study design: Prospective cohort study.
Setting: Multi-center, academic, and acute care hospitals.
Synopsis: The study examined 821 adults admitted to the ICU with respiratory failure, cardiogenic shock, or septic shock. Patients excluded were those with pre-existing cognitive impairment, those with psychotic disorders, and those for whom follow-up would not be possible. Two risk factors measured were duration of delirium and use of sedative/analgesics. Delirium was assessed at three and 12 months using the CAM-ICU algorithm in the ICU by trained psychology professionals who were unaware of the patients’ in-hospital course.
At three months, 40% of patients had global cognition scores that were 1.5 standard deviations (SD) below population mean (similar to traumatic brain injury), and 26% had scores two SD below population mean (similar to mild Alzheimer’s). At 12 months, 34% had scores similar to traumatic brain injury patients, and 24% had scores similar to mild Alzheimer’s. A longer duration of delirium was associated with worse global cognition at three and 12 months. Use of sedatives/analgesics was not associated with cognitive impairment.
Bottom line: Critically ill patients in the ICU who experience a longer duration of delirium are at risk of long-term cognitive impairments lasting 12 months.

Holding Chambers (Spacers) vs. Nebulizers for Acute Asthma
Clinical question: Are beta-2 agonists as effective when administered through a holding chamber (spacer) as they are when administered by a nebulizer?
Background: During an acute asthma attack, beta-2 agonists must be delivered to the peripheral airways. There has been considerable controversy regarding the use of a spacer compared with a nebulizer. Aside from admission rates and length of stay, factors taken into account include cost, maintenance of nebulizer machines, and infection control (potential of cross-infection via nebulizers).
Study design: Meta-analysis review of randomized controlled trials (RCTs).
Setting: Multi-centered, worldwide studies from community setting and EDs.
Synopsis: In 39 studies of patients with an acute asthma attack (selected from Cochrane Airways Group Specialized Register), the hospital admission rates did not differ on the basis of delivery method in 729 adults (risk ratio=0.94, confidence interval 0.61-1.43) or in 1,897 children (risk ratio=0.71, confidence interval 0.47-1.08). Secondary outcomes included the duration of time in the ED and the duration of hospital admission. Time spent in the ED varied for adults but was shorter for children with spacers (based on three studies). Duration of hospital admission also did not differ when modes of delivery were compared.
Bottom line: Providing beta-2 agonists using nebulizers during an acute asthma attack is not more effective than administration using a spacer.

ICU Pressures Improve Transfers to the Floor
Clinical question: Does ICU strain negatively affect the outcomes of patients transferred to the floor?
Background: With healthcare costs increasing and critical care staff shortages projected, ICUs will have to operate under increasing strain. This may influence decisions on discharging patients from ICUs and could affect patient outcomes.
Study design: Retrospective cohort study.
Setting: One hundred fifty-five ICUs in the United States.
Synopsis: Using the Project IMPACT database, 200,730 adult patients from 107 different hospitals were evaluated in times of ICU strain, determined by the current census, new admissions, and acuity level. Outcomes measured were initial ICU length of stay (LOS), readmission within 72 hours, in-hospital mortality rates, and post-ICU discharge LOS.
Increases of the strain variables from the fifth to the 95th percentiles resulted in a 6.3-hour reduction in ICU LOS, a 2.0-hour decrease in post-ICU discharge LOS, and a 1.0% increase in probability of ICU readmission within 72 hours. Mortality rates during the hospital stay and odds of being discharged home showed no significant change. This study was limited because the ICUs participating were not randomly chosen, outcomes of patients transferred to other hospitals were not measured, and no post-hospital data was collected, so no long-term outcomes could be measured.
Bottom line: ICU bed pressures prompt physicians to allocate ICU resources more efficiently without changing short-term patient outcomes.

Three-Month Dual Antiplatelet Therapy for Zotarolimus-Eluting Stents
Clinical question: Is short-term, dual antiplatelet therapy noninferior to long-term therapy in zotarolimus-eluting stents?
Background: Current guidelines recommend long-term (>12 months) dual antiplatelet therapy after the placement of drug-eluting stents. The optimal therapy duration in second-generation drug-eluting stents has not been studied; moreover, some studies with multiple drug-eluting stents have suggested no added benefit from long-term therapy.
Study design: Randomized controlled trial.
Setting: Brazil, multi-center.
Synopsis: Researchers randomized 3,211 patients with stable coronary artery disease (CAD) or low-risk acute coronary syndrome (ACS) undergoing intervention with zotarolimus-eluting stents to short-term (three months) or long-term (12 months) dual antiplatelet therapy. Exclusion criteria included ST-elevation myocardial infarction (STEMI), previous drug-eluting stent, scheduled elective surgery within 12 months, or contraindication to aspirin or clopidogrel. Primary endpoints were a composite of death from any cause, MI, stroke, or major bleeding. Secondary endpoints were stent thrombosis, target lesion revascularization, adverse cardiac event, and any bleed.
At one-year follow-up, the short-term group had similar primary (6.0% vs. 5.8%) and secondary (8.3% vs. 7.4%) outcomes compared to the long-term. The short-term group’s noninferiority also was seen in several key subgroups.
This study included patients with stable CAD or low-risk ACS and cannot be generalized to higher-risk patients. Results for zotarolimus-eluting stents cannot be generalized to other second-generation drug-eluting stents.
Bottom line: Zotarolimus-eluting stents, followed by three months of dual antiplatelet therapy, were noninferior to 12 months of therapy in patients with stable CAD or low-risk ACS.

Single vs. Dual Antiplatelet Therapy after Stroke
Clinical question: Is dual antiplatelet therapy more beneficial or harmful than monotherapy after ischemic stroke?
Background: It is recommended that patients with ischemic stroke or transient ischemic attack (TIA) receive lifelong antiplatelet therapy; however, there have been insufficient studies evaluating the long-term safety of dual antiplatelet therapy.
Study design: Meta-analysis of randomized controlled trials (RCTs)
Setting: Data from PubMed, Embase, and the Cochrane Central Register of Controlled Trials.
Synopsis: Data from seven RCTs, including 39,574 patients with recent TIA or ischemic stroke, were reviewed. Comparisons were made regarding occurrence of intracranial hemorrhage (ICH) and recurrent stroke between patients receiving dual antiplatelet therapy and those receiving aspirin or clopidogrel monotherapy. All patients were treated for at least one year.
There was no difference in recurrent stroke or ICH between patients on dual antiplatelet therapy versus aspirin monotherapy.

Endoscopic vs. Surgical Cystogastrostomy for Pancreatic Pseudocyst Drainage
Clinical question: How does endoscopic cystogastrostomy for pancreatic pseudocyst drainage compare to the standard surgical approach?
Background: Pancreatic pseudocysts are a common complication of pancreatitis and necessitate decompression when they are accompanied by pain, infection, or obstruction. Decompression of the pseudocyst can be accomplished using either endoscopic or surgical cystogastrostomy.
Study design: Open-label, single-center, randomized trial.
Setting: Single-center U.S. hospital.
Synopsis: A total of 40 patients were randomly equalized to both treatment arms; 20 patients underwent endoscopic and 20 patients underwent surgical cystogastrostomy. Zero patients in the endoscopic therapy had a pseudocyst recurrence, compared with one patient treated surgically. Length of stay (LOS) and cost were lower for the endoscopic group compared to the surgical group (two days vs. six days, P<0.001, $7,011 vs. $15,052, P=0.003).
This study is limited due to several factors. First, patients with pancreatic necrosis were excluded; had these patients been included, the complication rates and LOS would have been higher. Second, cost difference cannot be generalized across the U.S., because Medicare payments are based on provider types and regions.
Bottom line: Endoscopic cystogastrostomy for pancreatic pseudocyst is equal to the standard surgical therapy and results in decreased LOS and reduced costs.

Long-Term Cognitive Impairment after Critical Illness
Clinical question: Are a longer duration of delirium and higher doses of sedatives associated with cognitive impairment in the hospital?
Background: Survivors of critical illness are at risk for prolonged cognitive dysfunction. Delirium (and factors associated with delirium, namely sedative and analgesic medications) has been implicated in cognitive dysfunction.
Study design: Prospective cohort study.
Setting: Multi-center, academic, and acute care hospitals.
Synopsis: The study examined 821 adults admitted to the ICU with respiratory failure, cardiogenic shock, or septic shock. Patients excluded were those with pre-existing cognitive impairment, those with psychotic disorders, and those for whom follow-up would not be possible. Two risk factors measured were duration of delirium and use of sedative/analgesics. Delirium was assessed at three and 12 months using the CAM-ICU algorithm in the ICU by trained psychology professionals who were unaware of the patients’ in-hospital course.
At three months, 40% of patients had global cognition scores that were 1.5 standard deviations (SD) below population mean (similar to traumatic brain injury), and 26% had scores two SD below population mean (similar to mild Alzheimer’s). At 12 months, 34% had scores similar to traumatic brain injury patients, and 24% had scores similar to mild Alzheimer’s. A longer duration of delirium was associated with worse global cognition at three and 12 months. Use of sedatives/analgesics was not associated with cognitive impairment.
Bottom line: Critically ill patients in the ICU who experience a longer duration of delirium are at risk of long-term cognitive impairments lasting 12 months.

Holding Chambers (Spacers) vs. Nebulizers for Acute Asthma
Clinical question: Are beta-2 agonists as effective when administered through a holding chamber (spacer) as they are when administered by a nebulizer?
Background: During an acute asthma attack, beta-2 agonists must be delivered to the peripheral airways. There has been considerable controversy regarding the use of a spacer compared with a nebulizer. Aside from admission rates and length of stay, factors taken into account include cost, maintenance of nebulizer machines, and infection control (potential of cross-infection via nebulizers).
Study design: Meta-analysis review of randomized controlled trials (RCTs).
Setting: Multi-centered, worldwide studies from community setting and EDs.
Synopsis: In 39 studies of patients with an acute asthma attack (selected from Cochrane Airways Group Specialized Register), the hospital admission rates did not differ on the basis of delivery method in 729 adults (risk ratio=0.94, confidence interval 0.61-1.43) or in 1,897 children (risk ratio=0.71, confidence interval 0.47-1.08). Secondary outcomes included the duration of time in the ED and the duration of hospital admission. Time spent in the ED varied for adults but was shorter for children with spacers (based on three studies). Duration of hospital admission also did not differ when modes of delivery were compared.
Bottom line: Providing beta-2 agonists using nebulizers during an acute asthma attack is not more effective than administration using a spacer.

Hospitalists Join Together, Raise Bar on Global Health Initiatives
Western medicine has a long tradition of humanitarian service in developing countries. But, over the past two decades, the manner in which medical services are provided to under-resourced nations has evolved. Rather than volunteering to deliver acute care through humanitarian missions, a new generation of global health physicians aims to become dispensable. Through new nonprofit and collaborative models, they are establishing ongoing relationships with medical professionals in host countries to actively promote capacity building, from construction of new facilities to medical education and training.
“Global health work needs to be collaborative and bilateral, not just an export of our Western medical model to a low-resource setting,” says HealthPartners hospitalist Brett R. Hendel-Paterson, MD, an assistant professor of medicine at the University of Minnesota who also practices in HealthPartners’ Travel and Tropical Medicine Center in St. Paul, Minn., and is co-director of the UM/CDC online global health course.
Sriram Shamasunder, MD, DTM&H, hospitalist, health sciences assistant clinical professor, and co-director of the University of California San Francisco (UCSF) Global Health-Hospital Medicine Fellowship, agrees. “Mission medicine has incredibly well-meaning and committed people, but to address the upstream problems that bring people to the hospital, there need to be systems-based solutions,” he says.
And that is where hospitalists come in.
Growing numbers of hospitalists are joining in global health efforts, as Marwa Shoeb, MD, MS, and Phuoc Le, MD, MPH, DTM&H, discovered when they surveyed SHM members about participation in global health activities. Drs. Shoeb and Le are assistant clinical professors in the division of hospital medicine at UCSF. The survey (J Hosp Med. 2013;8(13):162-163) revealed that 51% of 232 respondents had done global health work prior to becoming a hospitalist; another third continued global health work after they began their HM careers.
Many believe hospitalists are uniquely qualified for global health initiatives. HM’s emphasis on systems of care delivery and quality improvement can supply much-needed knowledge as under-resourced countries strive to increase access to health care, says Michelle Morse, MD, MPH, an instructor in medicine at Harvard Medical School in Boston and deputy chief medical officer of Partners in Health (PIH) in Haiti (www.pih.org).
“Being a hospitalist is incredibly complementary to doing global health work,” Dr. Morse says. PIH has maintained a presence in Haiti for more than two decades and just recently celebrated a milestone with the Haitian medical community: establishment of the country’s newest medical residency training at University Hospital in Mirebalais.
Embrace Challenges
In early December, a group of UCSF hospitalists visited another PIH site, a Haitian Ministry of Health hospital in Hinche, located in the central plateau region of the country. Robin Tittle, MD, and Varun Verma, MD, were nearing the end of their first three-month rotation in the country as clinical fellows in the two-year-old Global Health-Hospital Medicine Fellowship.
According to Dr. Tittle, working in a resource-challenged hospital such as the one in Hinche is an irreplaceable experience. She and Dr. Verma discovered new levels of meaning in the term “workaround.” For example, “we have really limited lab capacity,” Dr. Tittle says. “One interesting thing I learned is how much your lab depends on access to reliable electricity. A number of our machines have been ruined because of electrical power surges. There are only certain people in the lab who know how to run certain tests.”
Dr. Tittle has learned that “you can’t practice medicine [in Haiti] without addressing the system.” Exposure to QI methods during training have been useful, she says, as she and Dr. Verma designed a medical education seminar for their Haitian colleagues by identifying the top 10 diagnoses in the nursing discharge registry. Still, she admits that the effort was hampered by nonspecific diagnoses—again a result of their inability to run diagnostic tests.
The learning has been reciprocal, notes Dr. Jacquelin Pierre Auguste, one of the Haitian internists in Hinche.
“We share a lot of knowledge,” he says, enthusiastically.
One example Dr. Pierre shared was being able to bring the clinical fellows into the case of a young mother who had developed postpartum cardiomyopathy. For unknown reasons, the condition is 10-20 times as common in Haiti as in the U.S., according to Dr. Le, who is co-director of the UCSF Global Health-Hospital Medicine Fellowship program. “Our fellows are also learning much more about the management of late-stage disease in tuberculosis and HIV,” he adds.
Several hospitalists have witnessed misappropriation of resources in global health projects, which can occur during emergency situations, such as in post-earthquake Haiti. For benefits to be sustainable, it’s best not to “charge in,” but to carefully assess the needs of the host setting. Although needs assessment should be handled by the sponsoring organization, hospitalists can contribute to this effort so that well-intentioned relief efforts do not cause unintended consequences, Dr. Hendel-Paterson says.
Hospitalists Unite
In the global health survey conducted in 2012, Drs. Shoeb and Le found that 46% of respondents were interested in collaborating with other hospitalists in order to increase their impact on health equity. In response to these and other observations about a need for mentorship, SHM established a Global Health and Human Rights Section, chaired by Drs. Shoeb and Le. They will be hosting a special global health forum at HM14 later this month in Las Vegas (www.hospitalmedicine2014.org).
The section goals are to:
- Provide a forum for like-minded hospitalists to share experiences and knowledge;
- Enhance the skill sets of hospitalists to apply their expertise in resource-poor settings; and
- Strengthen the capacity of local health systems through long-term collaborations and training in quality improvement.
Dr. Le, who has been affiliated with Partners in Health since his residency at Harvard Medical School, has spent time in sub-Saharan Africa as well as Haiti. He has been instrumental in advancing the HM global health agenda at UCSF and helped to organize the first national retreat on global health in HM last year. The program held its second annual retreat in February 2014.
Besides UCSF, two other global health fellowships are designed specifically for hospitalists: the University of Chicago Global Hospital Medicine Fellowship is headed by Evan Lyon, MD, an assistant professor of medicine in the section of hospital medicine in the UC Department of Medicine; the University of Florida College of Medicine’s Global Health-Hospitalist Fellowship program in Gainesville is headed by Vincent DeGennaro, Jr., MD, MPH, assistant professor in the division of hospital medicine.
In addition, hospitalist Deepak Asudani, MD, MPH, FHM, health sciences assistant clinical professor at the University of California San Diego, reports that his department is interested in organizing a global health fellowship program. A firm believer in the distinction between global health and international health, Dr. Asudani explains that the UCSD program will be geared to teach U.S.-trained physicians how to practice medicine in resource-limited countries. It will have a track for physicians from other countries to study hospital medicine here.
Sustainable Care
During their rotations in Haiti, Dr. Le says the UCSF clinical fellows’ mission is capacity building, meaning they usually do not deliver care as primary physicians but rather engage in what he calls “clinical accompaniment.” They assist with care delivery and teach clinical skills to Haitian trainees.
“We do not want to be a substitute for doctors who are there,” he says. “We want to support Haitian residents and give consultative advice on difficult cases. We do not want to go, provide care, and leave. We are moving toward long-term relationships that foster systemic change.”
Clinical fellows teach quality improvement methods, and then the local partners, whether in Liberia or Haiti, generate ideas for QI projects around their most pressing needs. The fellows then offer support in the development and implementation of those projects.
Congruent Practice
The global health program at the University of Minnesota, led by Patricia Walker, MD, DTM&H, has established a medical teaching collaboration with Selian Lutheran Hospital in Arusha, Tanzania. Its name, Tufundishane, is a Swahili word meaning “let us all teach one another” and points out one of the many benefits for hospitalists who pursue this type of work. They report that the work changes the way they practice when they resume clinical duties back home.
Dr. Verma, a UCSF clinical fellow, can attest to those changes. After a three-month stint at St. Thérèse Hospital in Hinche, Dr. Verma says he intended to challenge his residents on the teaching service to “think about every single test they’re ordering.” That resolve was just one consequence of working in a resource-challenged hospital environment.
Speaking from Hinche in December, Dr. Verma says that in the U.S., “you can order a complete blood count and electrolytes for your patients every day they’re in the hospital. But here, if I want to get a renal test on a patient, I have to find the lab manager and find out if we have the reagents for those tests. It makes me question whether I really need that test or whether I am ordering it to make myself feel better.”
Dr. Verma views the workaround challenges as a net positive.
“Many times, you can do a lot of good for patients with an incomplete picture,” he says. It’s a view shared by other hospitalists who incorporate global health work into their clinical duties back in the U.S.
Dr. Hendel-Paterson has a wealth of global health experience: He worked in India and Zimbabwe during medical school, conducted research in Uganda, volunteered in Haiti, and has taught a tropical medicine course in Thailand. He says hospitalists can benefit from knowledge about global health when treating their own patients. For example, seeing patients with malaria or dengue fever during volunteer or service work can help providers recognize, diagnose, and treat those diseases in returning U.S. travelers. It also can help hospitalists avoid causing iatrogenic disease, as in the case of disseminated strongyloidiasis, which can result when people who have lived in or visited endemic areas are treated with immunosuppressants like corticosteroids.
Even if the experience does not give enough expertise to diagnose and treat, he says it can help providers realize that they should be asking for more testing or consultation in appropriate settings.

Expand Your Thinking
Global health hospitalists interviewed by The Hospitalist believe good medicine is not tied to any particular place. Many find that work in other countries enriches their own core competencies as physicians.
As partnerships between health systems in other countries and the U.S. continue to grow, leaders hope the exchange will bring improvements for all parties. Dr. Shamasunder points out that as the healthcare dollar becomes scarcer in the U.S., those who work abroad might have much to contribute to the systems they work.
For Dr. Shamasunder and his colleagues, global health is not just about making people’s lives better but is also about taking into consideration the social determinants of health. What becomes clear after doing this work, he says, is that resource-challenged environments are everywhere and that patients’ social histories are relevant no matter the locale.
“If you simply treat a patient who has anemia from lead exposure, and you have no mechanism to address the presence of that toxin in their substandard housing, that patient may end up with lead poisoning,” he says.
As Dr. Hendel-Paterson sums it up: “There is no such thing as healthcare over here and healthcare over there.” That’s why he and other global health hospitalists are convinced that “global is local.”

Clinical fellows teach quality improvement methods, and then the local partners, whether in Liberia or Haiti, generate ideas for QI projects around their most pressing needs. The fellows then offer support in the development and implementation of those projects.
Congruent Practice
The global health program at the University of Minnesota, led by Patricia Walker, MD, DTM&H, has established a medical teaching collaboration with Selian Lutheran Hospital in Arusha, Tanzania. Its name, Tufundishane, is a Swahili word meaning “let us all teach one another” and points out one of the many benefits for hospitalists who pursue this type of work. They report that the work changes the way they practice when they resume clinical duties back home.
Dr. Verma, a UCSF clinical fellow, can attest to those changes. After a three-month stint at St. Thérèse Hospital in Hinche, Dr. Verma says he intended to challenge his residents on the teaching service to “think about every single test they’re ordering.” That resolve was just one consequence of working in a resource-challenged hospital environment.
Speaking from Hinche in December, Dr. Verma says that in the U.S., “you can order a complete blood count and electrolytes for your patients every day they’re in the hospital. But here, if I want to get a renal test on a patient, I have to find the lab manager and find out if we have the reagents for those tests. It makes me question whether I really need that test or whether I am ordering it to make myself feel better.”
Dr. Verma views the workaround challenges as a net positive.
“Many times, you can do a lot of good for patients with an incomplete picture,” he says. It’s a view shared by other hospitalists who incorporate global health work into their clinical duties back in the U.S.
Dr. Hendel-Paterson has a wealth of global health experience: He worked in India and Zimbabwe during medical school, conducted research in Uganda, volunteered in Haiti, and has taught a tropical medicine course in Thailand. He says hospitalists can benefit from knowledge about global health when treating their own patients. For example, seeing patients with malaria or dengue fever during volunteer or service work can help providers recognize, diagnose, and treat those diseases in returning U.S. travelers. It also can help hospitalists avoid causing iatrogenic disease, as in the case of disseminated strongyloidiasis, which can result when people who have lived in or visited endemic areas are treated with immunosuppressants like corticosteroids.
Even if the experience does not give enough expertise to diagnose and treat, he says it can help providers realize that they should be asking for more testing or consultation in appropriate settings.

Expand Your Thinking
Global health hospitalists interviewed by The Hospitalist believe good medicine is not tied to any particular place. Many find that work in other countries enriches their own core competencies as physicians.
As partnerships between health systems in other countries and the U.S. continue to grow, leaders hope the exchange will bring improvements for all parties. Dr. Shamasunder points out that as the healthcare dollar becomes scarcer in the U.S., those who work abroad might have much to contribute to the systems they work.
For Dr. Shamasunder and his colleagues, global health is not just about making people’s lives better but is also about taking into consideration the social determinants of health. What becomes clear after doing this work, he says, is that resource-challenged environments are everywhere and that patients’ social histories are relevant no matter the locale.
“If you simply treat a patient who has anemia from lead exposure, and you have no mechanism to address the presence of that toxin in their substandard housing, that patient may end up with lead poisoning,” he says.
As Dr. Hendel-Paterson sums it up: “There is no such thing as healthcare over here and healthcare over there.” That’s why he and other global health hospitalists are convinced that “global is local.”

Society of Hospital Medicine Creates Self-Assessment Tool for Hospitalist Groups
Are you looking to improve your hospital medicine group (HMG)? Would you like to measure your group against other groups?
The February 2013 issue of the Journal of Hospital Medicine included a seminal article for our specialty, “The Key Principles and Characteristics of an Effective Hospital Medicine Group: an assessment guide for hospitals and hospitalists.” This paper has received a vast amount of attention around the country from hospitalists, hospitalist leaders, HMGs, and hospital executives. The report (www.hospitalmedicine.org/keychar) is a first step for physicians and executives looking to benchmark their practices, and it has stimulated discussions among many HMGs, beginning a process of self-review and considering action.
I am coming up on my 20th year as a hospitalist, and the debate over what makes a high-performing HMG has continued that entire time. In the beginning, there were questions about the mere existence of hospital medicine and HMGs. The discussion about what makes a high-performing HMG started among the physicians, medical groups, and hospitals that signed on early to the HM movement. At conferences, HMG leaders debated how to set up a program. A series of pioneer hospitalists, many with only a few years of experience, roamed the country as consultants giving advice on best practices. A professional society, the National Association of Inpatient Physicians, was born and, later, recast as the Society of Hospital Medicine (SHM)—and the discussion continued.
SHM furthered the debate with such important milestones as The Core Competencies in Hospital Medicine: A Framework for Curriculum Development, white papers on career satisfaction and hospitalist involvement in quality/safety and transitions of care. Different types of practice arrangements developed. Some were hospital-based, some physician practice-centered. Some were local, and others were regional and national. Each of these spawned innovations in HMG processes and contributed to the growing body of best practices.
Over the past five years, a consensus regarding those best practices has seemingly developed, and the discussions are centered on fine details rather than significant differences. To that end, approximately three years ago, a small group of SHM members met and discussed how to capture this information and disseminate it better among hospitalists, HMGs, and hospitals. We had all come to a similar conclusion—high-performing HMGs share common characteristics. Furthermore, every hospital and HMG seeks excellence, striving to be the best that they can be. We settled on a plan to write this up.
After a year of debate, we sought SHM’s help in the development phase and, in early 2012, SHM’s board of directors appointed a workgroup to identify the key principles and characteristics of an effective HMG. The initial group was widened to make sure we included different backgrounds and experiences in hospital medicine. The group had a wide array of involvement in HMG models, including HMG members, HMG leaders, hospital executives, and some involved in consulting. Many of the individuals had multiple experiences. The conversation among these individuals was lively!
The workgroup developed an initial draft of characteristics, which then went through a multi-step process of review and redrafting. More than 200 individuals, representing a broad group of stakeholders in hospital medicine and in the healthcare industry in general, provided comments and feedback. In addition, the workgroup went through a two-step Delphi process to consolidate and/or eliminate characteristics that were redundant or unnecessary.
In the final framework, 47 key characteristics were defined and organized under 10 principles (see Figure 1).
The authors and SHM’s board of directors view this document as an aspirational approach to improvement. We feel it helps to “raise the bar” for the specialty of hospital medicine by laying out a roadmap of potential improvement. These principles and characteristics provide a framework for HMGs seeking to conduct self-assessments, outlining a pathway for improvement, and better defining the central role of hospitalists in coordinating team-based, patient-centered care in the acute care setting.
In enhancing quality, the approach of a gap analysis is a very effective tool. These principles provide an excellent approach to begin that review.
So how do you get started? Hopefully, your HMG has a regular meeting. Take a principle and have a conversation. For example, what do we have? What don’t we have?
Other groups may want to tackle the entire document in a daylong strategy review. Some may want an outside facilitator. Bottom line: It doesn’t matter how you do it; just start with a conversation.
