Pancreas and Biliary Tract

For the pancreatobiliary session, Michelle Ann Anderson, MD, of the University of Michigan, Ann Arbor, reminded us about appropriate patient selection given the risk of pancreatitis after endoscopic retrograde cholangiopancreatography pancreatitis, also known as post-ERCP pancreatitis. Strategies to prevent post-ERCP pancreatitis include using pancreatic duct stents and using wire rather than contrast for cannulation. She recommended rectal indomethacin for all patients. Because of encouraging data, she recommended 2-3 L of lactated Ringer’s solution during the procedure and recovery. 

Katie Morgan, MD, from the Medical University of South Carolina, Charleston, reviewed her group’s experience with 195 total pancreatectomies with islet autotransplants for chronic pancreatitis. Quality of life improved with major reductions in narcotic use, and 25% of patients were insulin free. 

Bret Petersen, MD, of Mayo Clinic, Rochester, Minn., discussed multidrug resistant infection in ERCP endoscopes. He reminded us of the risk of lapses in endoscope reprocessing steps and the need for monitoring. He commented on recent Food and Drug Administration’s culture guidance and new technologies in development. 

James Scheiman, MD, from the University of Virginia, Charlottesville, discussed pancreatic cysts. He reviewed the controversy between the more conservative American Gastroenterological Association guidelines and the more aggressive International Consensus guidelines. He advised considering patient preferences with a multidisciplinary approach.
For the liver session, Guadalupe García-Tsao, MD, of Yale University, New Haven, Conn., discussed the controversy regarding nonselective beta-blockers. She advised caution if refractory ascites are present because of risk for renal dysfunction, but she also highlighted the benefits including reduced first and recurrent variceal hemorrhage. 

Rohit Loomba, MD, from the University of California at San Diego addressed fibrosis assessments in fatty liver. In his algorithm, patients with low Nonalcoholic Fatty Liver Disease Fibrosis Score or Fibrosis-4 scores would have continued observation, while patients with medium or high scores would undergo transient elastography or magnetic resonance elastography. 

Patrick Northup, MD, from the University of Virginia discussed anticoagulation for portal vein thrombosis. He also discussed consideration of transjugular intrahepatic portosystemic shunt if there are high-risk varices. Duration of anticoagulation is controversial, but this strategy may prevent decompensation and affect transplant outcomes. 

Daryl Lau, MD, MSc, MPH, from Harvard Medical School, Boston, reviewed the hepatitis B virus therapy controversy for e-antigen–negative patients with prolonged viral suppression. She recommended caution in general and emphasized that stage 3-4 fibrosis patients should not discontinue therapy. 

The final talk was my review of hepatitis C virus treatment. I emphasized that pretreatment fibrosis assessments are critical given continued risk of hepatocellular carcinoma after cure. Challenges include identifying the remaining patients and supporting them through treatment. HCV therapies demonstrate what is possible when breakthroughs are translated to clinical care, and I was honored to participate in this course that highlighted many advances in our field.

Long-term pancreatic surveillance of high-risk patients identified cancers while they were still resectable, and 85% of such patients remained alive 3 years after diagnosis, researchers reported.

“Among individuals undergoing pancreatic surveillance, specific detectable lesions with worrisome features predicted neoplastic progression. The short-term outcomes of patients with screening-detected PDACs [pancreatic ductal adenocarcinomas] improved,” wrote Marcia Irene Canto, MD, MHS, of the Johns Hopkins University, Baltimore, together with her associates in the September issue of Gastroenterology.

The lifetime risk of PDAC is about 1.5%, the researchers noted. Consequently, the U.S. Preventive Services Task Force does not recommend pancreatic surveillance at a population level. However, pancreatic screening is being evaluated for individuals who are at significantly elevated risk of PDAC, including those with at least two first-degree relatives with PDAC or who have germline mutations in BRCA1, BRCA2, PALB2, PRSS1 (hereditary pancreatitis), CDKN2A, MLH1, MSH2, MSH6, PMS2 (Lynch syndrome), or STK11 (Peutz-Jeghers syndrome).

For the study, Dr. Canto and her associates analyzed data from 354 such high-risk individuals enrolled in the CAPS (Cancer of the Pancreas Screening) cohort studies, which were conducted at tertiary care academic centers during 1998-2014. All participants underwent endoscopic ultrasound at baseline, followed by surveillance with endoscopic ultrasound, magnetic resonance imaging, computed tomography, or some combination of these modalities. Patients who developed pancreatic cancer or high-grade dysplasia were offered surgery.

In all, 68 patients (19%) developed pancreatic lesions with worrisome features, such as solid masses, multiple cysts, mural nodules, thickened or enhancing walls, cysts exceeding 3 cm in size or that grew more than 4 mm annually, a greater than 5-mm dilation of the main pancreatic duct, or an abrupt change in duct caliber. The lesions developed over a median of 13.1 months (interquartile range, 0.2-52 months).

A total of 7% of patients had neoplastic progression, including 14 cases of PDAC and 10 cases of high-grade dysplasia. Median times from baseline to detection of PDAC were 4.8 years overall (IQR, 1.6-6.9 years), 1.7 years (IQR, 0.5-4.4 years) among patients aged at least 60 years at baseline, and 5.2 years among younger patients (IQR, 0.4-8 years). Patients developed PDAC at a median of 67 years old.

Among 10 PDACs detected by surveillance, 9 were resectable. Three patients subsequently died of PDAC, while one patient died of complications of gastric cancer surgery. However, 85% of patients survived for at least 3 years after surgical resection of PDAC. The remaining four cases of PDAC were detected outside surveillance or after patients stopped surveillance.

The 10 cases of high-grade dysplasia consisted of intraductal papillary mucinous neoplasm with high-grade dysplasia or high-grade pancreatic intraepithelial neoplasia. Patients whose PDAC or high-grade dysplasia was detected by surveillance survived a median of 5.3 years, while patients whose surveillance was late or stopped and who subsequently developed neoplasia survived a median of only 1.4 years after diagnosis (P less than .0001).

Funders included the Pancreatic Cancer Action Network, Lustgarten Foundation for Pancreatic Cancer Research, the John and Peter Hooven Memorial Endowment, Hugh and Rachel Victor, and ChiRhoClin. Dr. Canto had no disclosures. Three coinvestigators disclosed royalties for licensing of PALB2 as a pancreatic cancer susceptibility gene.

The number of U.S. emergency department visits for acute pancreatitis associated with alcohol abuse, chronic pancreatitis history, and younger age was on the rise in recent years, an analysis of a nationally representative database has suggested.

Katarzyna Bialasiewicz/Thinkstock

Meanwhile, hospital admissions and length of stay dropped, but ED and inpatient charges increased, according to the analysis by Sushil K. Garg, MD, of the division of gastroenterology and hepatology at the Mayo Clinic, Rochester, Minn., and his coauthors.

“This study identifies important patient populations, specifically young patients with alcohol abuse, to target in order to develop programs to assist in reduction of ED utilization for acute pancreatitis,” Dr. Garg and his colleagues reported in the Journal of Clinical Gastroenterology.

The retrospective analysis was focused on nearly 2.2 million ED visits during 2006-2012 in the National Emergency Department Sample (NEDS) database. The cohort was limited to adults at least 18 years of age with a primary diagnosis of acute pancreatitis.

Overall, there was a nonsignificant 5.5% increase in visits per 10,000 U.S. population during 2006-2012, the researchers found. However, the total number of ED visits in this sample increased significantly – from 292,902 in 2006 to a peak of 326,376, an average rate of increase of 7,213 visits per year (P = .0086), according to the report.

Younger patients had a significant increase in the number of pancreatitis-related ED visits over the study period, while older patients had a significant decrease, according to investigators. Visits were up 9.2% for patients aged 18-44 years and 8.6% for those aged 45-64 but down 13.4% for patients aged 65-84 years and 20.1% for those aged 85 years or older.

The incidence of visits secondary to biliary disease was virtually flat over time, Dr. Garg and his coinvestigators found when looking at visits grouped by the most common presenting etiologies. By contrast, there were significant increases in visits for acute pancreatitis associated with alcohol abuse or chronic pancreatitis.

Specifically, acute pancreatitis associated with biliary disease averaged 20.7% of yearly pancreatitis-related ED visits and did not significantly change over time, the researchers reported.

By contrast, acute pancreatitis associated with alcohol abuse, which accounted for 24.1% of visits on average, increased by 15.9% over the study period, an increase driven by an increase among age groups younger than 65 years.

Acute pancreatitis associated with chronic pancreatitis, which made up 11.5% of visits on average, increased “substantially” in all age groups, according to study authors, with the largest increase in the group aged 45-64 years. Overall, the percentage increase over 7 years was 59.5%.

Rates of hospitalization decreased significantly over time, from 76.2% in 2006 to 72.7% in 2012 (P = .0026), and likewise, the length of stay dropped from 5.36 to 4.64 days (P = .0001), according to the analysis.

Inpatient charges, adjusted for inflation and expressed in 2012 dollars, increased from $32,130.63 to $34,652.00 (P = .0011), an average rate of increase of $489/year.

Predictors of hospitalization included age older than 84 years, alcohol use, smoking, and a Charlson comorbidity score of 1 or greater, according to the results of a multivariate regression analysis.

“Factors which may place patients at higher risk for severe or complicated acute pancreatitis requiring admission, such as obesity, alcohol use, and increasing age, are identified and should be explored in further studies and potentially targeted to improve ED and inpatient care,” Dr. Garg and his coauthors said.

Dr. Garg and his coauthors had no disclosures related to the study.

Researchers have identified laminin 511 as a novel antigen in autoimmune pancreatitis (AIP). A truncated form of the antigen was found in about half of human patients, but fewer than 2% of controls, and mice that were immunized with the antigen responded with induced antibodies and suffered pancreatic injury.

Laminin 511 plays a key role in cell–extracellular matrix (ECM) adhesion in pancreatic tissue. The results, published in Science Translational Medicine, could improve the biologic understanding of AIP and could potentially be a useful diagnostic marker for the disease.

Some autoantibodies are known to be associated with AIP, but the seropositive frequency is low among patients.

The researchers previously demonstrated that injecting IgG from AIP patients into neonatal mice led to pancreatic injury. The IgG was bound to the basement membrane of the pancreatic acini, suggesting the presence of autoantibodies that recognize an antigen in the ECM.

The researchers then screened previously known proteins from the pancreatic ECM against sera from AIP patients, performing Western blot analyses and immunosorbent column chromatography with human and mouse pancreas extracts, and AIP patient IgG. But this approach yielded no results.

The team then conducted an enzyme-linked immunosorbent assay using known pancreatic ECM proteins, which included the laminin subunits 511-FL, 521-FL, 511-E8, 521-E8, 111-EI, 211-E8, and 332-E8. The E8 designates a truncated protein produced by pancreatic elastase that contains the integrin-binding site.

That experiment revealed that 511-E8 is a consistent autoantigen, and a survey of AIP patients found that 26 of 51 (51.0%) had autoantibodies against 511-E8, compared with just 2 of 122 (1.6%) of controls (P less than .001). Further immunohistochemistry studies confirmed that patient IgG binds to laminin in pancreatic tissue.

When the researchers injected 511-E8, 511-FL, 521-FL, or ovalbumin into 8-week-old mice, and then again after 28 days and 56 days, only those who received 511-E8 showed evidence of pancreatic injury 28 days after the final immunization. The mice generated autoantibodies to 511-E8 but not ovalbumin.

The findings may have clinical significance. Patients with antibodies to laminin 511-E8 had a lower frequency of malignancies (0% vs. 32%; P =.0017) and allergic diseases (12% vs. 48%; P =.0043) than patients with no laminin 511-E8 antibodies.

The study was funded by the Japan Society for the Promotion of Science; the Japanese Ministry of Health, Labour, and Welfare; the Practical Research Project for Rare/Intractable Diseases Grant,; the Agency for Medical Research and Development; and the Takeda Science Foundation. One of the authors has filed a patent related to the study results.

Patients with acute pancreatitis should receive “goal-directed” fluid therapy with normal saline or Ringer’s lactate solution rather than hydroxyethyl starch (HES) fluids, states a new guideline from the AGA Institute.

In a single-center randomized trial, hydroxyethyl starch fluids conferred a 3.9-fold increase in the odds of multiorgan failure (95% confidence interval for odds ratio, 1.2-12.0) compared with normal saline in patients with acute pancreatitis, wrote guideline authors Seth D. Crockett, MD, MPH, of the University of North Carolina, Chapel Hill, and his associates. This trial and another randomized study found no mortality benefit for HES compared with fluid resuscitation. The evidence is “very low quality” but mirrors the critical care literature, according to the experts. So far, Ringer’s lactate solution and normal saline have shown similar effects on the risk of organ failure, necrosis, and mortality, but ongoing trials should better clarify this choice, they noted (Gastroenterology. doi: 10.1053/j.gastro.2018.01.032).

The guideline addresses the initial 2-week period of treating acute pancreatitis. It defines goal-directed fluid therapy as titration based on meaningful targets, such as heart rate, mean arterial pressure, central venous pressure, urine output, blood urea nitrogen concentration, and hematocrit. Studies of goal-directed fluid therapy in acute pancreatitis have been unblinded, have used inconsistent outcome measures, and have found no definite benefits over nontargeted fluid therapy, note the guideline authors. Nevertheless, they conditionally recommend goal-directed fluid therapy, partly because a randomized, blinded trial of patients with severe sepsis or septic shock (which physiologically resembles acute pancreatitis) had in-hospital mortality rates of 31% when they received goal-directed fluid therapy and 47% when they received standard fluid therapy (P = .0009).

The guideline recommends against routine use of two interventions: prophylactic antibiotics and urgent endoscopic retrograde cholangiopancreatography (ERCP) for patients with acute pancreatitis. The authors note that no evidence supports routine prophylactic antibiotics for acute pancreatitis patients without cholangitis, and that urgent ERCP did not significantly affect the risk of mortality, multiorgan failure, single-organ failure, infected pancreatic and peripancreatic necrosis, or necrotizing pancreatitis in eight randomized controlled trials of patients with acute gallstone pancreatitis.

Gadolinium-based contrast agents (GBCAs) used for MRI will now carry a warning regarding their potential retention in the bodies and brains of treated patients, according to the Food and Drug Administration.

The FDA is requiring the new class warning, along with other safety measures, based on evidence showing that trace amounts of gadolinium can be retained in the body for months to years after treatment.

Specifically, the agency will require that patients receiving GBCAs first receive a Medication Guide and that GBCA manufacturers conduct human and animal studies to further assess GBCA safety. At this time, the only known adverse health effect of gadolinium retention is nephrogenic systemic fibrosis, which affects a small subgroup of patients with pre-existing kidney failure. No causal association has been established between gadolinium retention and reported adverse events in those with normal kidney function.

The FDA recommended that health care professionals consider the retention characteristics of GBCAs for patients who may be at higher risk for retention, including those requiring multiple lifetime doses, pregnant women, children, and patients with inflammatory conditions, but stressed that, although repeated GBCA imaging studies should be minimized when possible, they should not be avoided or deferred when they are necessary. In the safety alert, the FDA noted that administration of the GBCAs Dotarem (gadoterate meglumine), Gadavist (gadobutrol), and ProHance (gadoteridol) produce the lowest gadolinium levels in the body, and the three agents leave similar gadolinium levels in the body.

The agency encourages reports of adverse events or side effects related to the use of GBCAs to its MedWatch Safety information and Adverse Event Reporting Program. Reports can be submitted online at www.fda.gov/MedWatch/report or by calling 1-800-332-1088 to request a preaddressed form that can be mailed or faxed to 1-800-FDA-0178.

In patients with malignant biliary strictures, radiofrequency ablation may improve stent patency and prolong survival, according to results of a recent meta-analysis.

Radiofrequency ablation was also safe and well tolerated. The report appears in Gastrointestinal Endoscopy (2017. doi: 10.1016/j.gie.2017.10.029).

Although the data to date are limited and mostly observational, radiofrequency ablation “may be a promising adjuvant therapy in patients with malignant biliary obstruction who otherwise have dismal outcomes with current standard of therapy,” wrote Aijaz Ahmed Sofi, MD, of the department of gastroenterology, Arizona Center for Digestive Health, Gilbert, and coauthors.

Use of radiofrequency ablation is thought to improve the patency of biliary stents placed as a palliative measure in patients with unresectable malignant biliary strictures. However, several studies evaluating this and other endpoints have produced “variable results,” the authors said in the report.

In a comprehensive literature search, Dr. Sofi and colleagues identified nine studies including 505 patients. Only one of the studies was randomized and controlled, and results from it were preliminary, they noted.

Combined results showed a 50.6-day pooled weighted mean difference in stent patency (95% confidence interval, 32.83-68.48) in favor of radiofrequency ablation, according to reported data. In addition, there was a significant difference in survival favoring use of radiofrequency ablation (hazard ratio, 1.395; 95% confidence interval, 1.145-1.7; P less than .001).

While there was no difference between groups in risk of cholangitis, pancreatitis, hemobilia, and acute cholecystitis, abdominal pain after the procedure was more frequent in the radiofrequency ablation group (31% vs. 20%, P = .003).

This is the first systematic review and meta-analysis evaluating radiofrequency ablation as an adjuvant therapy in patients who receive biliary stents for malignant biliary obstruction, according to the investigators.

Despite the findings, Dr. Sofi and colleagues were careful to emphasize the limitations of the analysis, writing that it provides “very low quality evidence” in favor of radiofrequency ablation therapy for management of malignant biliary strictures.

“The results of currently ongoing controlled studies examining the role of RFA [radiofrequency ablation] in malignant biliary obstruction are keenly awaited,” they wrote.

Dr. Sofi and colleagues reported no potential conflicts of interest associated with the study.

ORLANDO – An endoscopic approach to treatment of acute necrotizing pancreatitis was substantially safer than was minimally invasive surgical treatment in a randomized study of 66 patients.

Performing drainage and necrosectomy endoscopically in 34 patients with necrotizing pancreatitis that was symptomatic, infected, or both resulted in a 12% rate of major adverse events over the 3 months following intervention compared with a 38% rate among 32 similar patients who underwent laparoscopic drainage followed by either internal debridement or video-assisted retroperitoneal debridement, Ji Young Bang, MD, said at the World Congress of Gastroenterology at ACG 2017.

This statistically significant reduction in the study’s primary endpoint was driven primarily by a major reduction in the incidence of pancreaticocutaneous fistula, which occurred in none of the endoscopy patients and in eight (25%) of the surgery patients, and a smaller reduction in enterocutaneous fistula, which occurred in none of the endoscopy patients and in four (13%) of the patients treated surgically, said Dr. Bang, a gastroenterologist at the Center for Interventional Endoscopy at Florida Hospital, Orlando.

Based on these results, the endoscopic approach “is the treatment of the future,” Dr. Bang said in a video interview. Although the randomized study had a modest number of patients, it was adequately powered to address the hypothesis that endoscopy caused fewer major adverse events than did minimally invasive surgery, and hence the findings should have “an important clinical impact” on the choice of endoscopy or a minimally invasive surgical approach. But Dr. Bang also stressed that a successful endoscopic approach as obtained in this study requires treatment at a center that can offer multidisciplinary expertise from gastrointestinal endoscopists, surgeons, and radiologists, as well as infectious disease physicians, to minimize infections.

Prior to this study, results from the Pancreatitis, Endoscopic Transgastric vs Primary Necrosectomy in Patients With Infected Necrosis (PENGUIN) study run in the Netherlands had also shown significantly fewer adverse events with endoscopic treatment compared with laparoscopic surgery in 20 randomized patients (JAMA. 2012 Mar 14;307[10]:1053-61).

The study reported by Dr. Bang, the Minimally Invasive Surgery vs. Endoscopy Randomized (MISER) trial, enrolled patients with an average necrotic collection size of about 11 cm. The average age of the patients was 59 years. Nearly half of the patients had confirmed infected necrosis. More than 90% had American Society of Anesthesiologists class III or IV disease, and about half had systemic inflammatory response syndrome. All patients had disease that was amenable to both the endoscopic and minimally invasive surgical approaches.

The study’s primary endpoint included several other adverse events in addition to fistulas during 3-month follow-up: death, new-onset organ failure or multiple systemic dysfunction, visceral perforation, and intra-abdominal bleeding. The incidence of each of these outcomes was about the same in the two study arms.

The results also showed that endoscopy was significantly better than surgery for several other secondary outcomes, including new-onset systemic inflammatory response syndrome as well as the prevalence of this complication 3 days after intervention (21% compared with 66%), days in the ICU, average total procedure and hospitalization cost ($76,000 compared with $117,000), and physical quality of life 3 months after treatment. For all other measured outcomes the endoscopic approach and surgical approach produced similar outcomes, and no outcome measured showed that endoscopy was significantly inferior to surgery, Dr. Bang reported.

ORLANDO – An endoscopic approach to treatment of acute necrotizing pancreatitis was substantially safer than was minimally invasive surgical treatment in a randomized study of 66 patients.

Performing drainage and necrosectomy endoscopically in 34 patients with necrotizing pancreatitis that was symptomatic, infected, or both resulted in a 12% rate of major adverse events over the 3 months following intervention compared with a 38% rate among 32 similar patients who underwent laparoscopic drainage followed by either internal debridement or video-assisted retroperitoneal debridement, Ji Young Bang, MD, said at the World Congress of Gastroenterology at ACG 2017.

This statistically significant reduction in the study’s primary endpoint was driven primarily by a major reduction in the incidence of pancreaticocutaneous fistula, which occurred in none of the endoscopy patients and in eight (25%) of the surgery patients, and a smaller reduction in enterocutaneous fistula, which occurred in none of the endoscopy patients and in four (13%) of the patients treated surgically, said Dr. Bang, a gastroenterologist at the Center for Interventional Endoscopy at Florida Hospital, Orlando.

Based on these results, the endoscopic approach “is the treatment of the future,” Dr. Bang said in a video interview. Although the randomized study had a modest number of patients, it was adequately powered to address the hypothesis that endoscopy caused fewer major adverse events than did minimally invasive surgery, and hence the findings should have “an important clinical impact” on the choice of endoscopy or a minimally invasive surgical approach. But Dr. Bang also stressed that a successful endoscopic approach as obtained in this study requires treatment at a center that can offer multidisciplinary expertise from gastrointestinal endoscopists, surgeons, and radiologists, as well as infectious disease physicians, to minimize infections.

Prior to this study, results from the Pancreatitis, Endoscopic Transgastric vs Primary Necrosectomy in Patients With Infected Necrosis (PENGUIN) study run in the Netherlands had also shown significantly fewer adverse events with endoscopic treatment compared with laparoscopic surgery in 20 randomized patients (JAMA. 2012 Mar 14;307[10]:1053-61).

The study reported by Dr. Bang, the Minimally Invasive Surgery vs. Endoscopy Randomized (MISER) trial, enrolled patients with an average necrotic collection size of about 11 cm. The average age of the patients was 59 years. Nearly half of the patients had confirmed infected necrosis. More than 90% had American Society of Anesthesiologists class III or IV disease, and about half had systemic inflammatory response syndrome. All patients had disease that was amenable to both the endoscopic and minimally invasive surgical approaches.

The study’s primary endpoint included several other adverse events in addition to fistulas during 3-month follow-up: death, new-onset organ failure or multiple systemic dysfunction, visceral perforation, and intra-abdominal bleeding. The incidence of each of these outcomes was about the same in the two study arms.

The results also showed that endoscopy was significantly better than surgery for several other secondary outcomes, including new-onset systemic inflammatory response syndrome as well as the prevalence of this complication 3 days after intervention (21% compared with 66%), days in the ICU, average total procedure and hospitalization cost ($76,000 compared with $117,000), and physical quality of life 3 months after treatment. For all other measured outcomes the endoscopic approach and surgical approach produced similar outcomes, and no outcome measured showed that endoscopy was significantly inferior to surgery, Dr. Bang reported.

Enhanced recovery approaches were safe and effective at promoting earlier restoration of gut function in acute pancreatitis patients, according to a study presented at the World Congress of Gastroenterology at ACG 2017.

Patients recruited for the trial were admitted directly from an emergency department and received either enhanced care consisting of patient-directed oral intake, early ambulation, and nonopioid analgesia or received normal care consisting of opioid analgesia, physician-directed diet, and nursing parameters, Elizabeth Dong, MD, of the Kaiser Permanente Los Angeles Medical Center and her associates said.

Among the 46 patients included in the study, 61% had an etiology of gallstones, 15% had an etiology of alcohol, 13% had hyperglyceridemia, and 11% had a different etiology. Median age was 53.1 years, Dr. Dong and her associates noted.

Time to successful oral refeeding, the primary study endpoint, was significantly reduced in the enhanced treatment group, with a median time of 13.8 hours, compared with the normal treatment group, in which median time to oral refeeding was 124.8 hours. In addition, patients in the enhanced care group had a mean pancreatitis activity score of 43.5 after 48-72 hours, while patients in the control group had a mean score of 72.1.

Length of stay and frequency of 30-day readmission did not differ significantly between study groups.

The study was not funded by industry grants, and no disclosures were reported.
