Surgery

Secondary surgical cytoreduction was feasible but did not extend overall survival among women with platinum-sensitive, recurrent ovarian cancer in a prospective, randomized, phase 3 clinical trial, investigators report.

Women who received platinum-based chemotherapy plus surgery had a median overall survival of about 51 months, compared with 64.7 months for women who received platinum-based chemotherapy and no surgery, according to the results of the Gynecologic Oncology Group (GOG)-0213 study, a multicenter, open-label, randomized, phase 3 trial.

These findings “call into question” the merits of surgical cytoreduction, said the authors, led by Robert L. Coleman, MD, of the department of gynecologic oncology and reproductive medicine at the University of Texas M.D. Anderson Cancer Center, Houston.

Specifically, the shorter overall survival in the surgery group vs. no-surgery group emphasizes the “importance of formally assessing the value of the procedure in clinical care,” said Dr. Coleman and coauthors in the report on GOG-0213. The study was published in the New England Journal of Medicine.

Clinical practice guidelines from the National Comprehensive Cancer Network currently cite secondary cytoreduction as an option for treatment of patients who experience a treatment-free interval of at least 6 months after a complete remission achieved on prior chemotherapy, the GOG-0213 investigators wrote.

Beyond GOG-0213, there are several other randomized trials underway in this setting, including DESKTOP III, a multicenter study comparing the efficacy of chemotherapy alone to chemotherapy plus additional tumor debulking surgery in women with recurrent platinum-sensitive ovarian cancer.

“Maturity of the DESKTOP III trial and other trials will shape the debate on the value or merit of surgery in this patient population,” wrote Dr. Coleman and colleagues.

The GOG-0213 study, conducted in 67 centers, 65 of which were in the United States, had both a chemotherapy objective and a surgical objective in patients with platinum-sensitive recurrent ovarian cancer, investigators said.

Results of the chemotherapy objective, published in 2017 in Lancet Oncology, indicated that bevacizumab added to standard chemotherapy, followed by maintenance bevacizumab until progression, improved median overall survival.

The more recently reported results focused on 485 women of who 245 were randomized to receive chemotherapy alone. While 240 were randomized to receive cytoreduction prior to chemotherapy, 15 declined surgery, leaving 225 eligible patients (94%).

The adjusted hazard ratio for death was 1.29 (95% confidence interval, 0.97-1.72; P = 0.08) for surgery, compared with no surgery, which translated into median overall survival times of 50.6 months in the surgery arm and 64.7 months in the no-surgery arm, Dr. Coleman and coauthors reported.

However, 30-day morbidity and mortality were low, at 9% (20 patients) and 0.4% (1 patient), and just 4% of cases (8 patients) were aborted, they added.

Quality of life significantly declined right after secondary cytoreduction, although after recovery no significant differences were found between groups, according to the investigators.

Taken together, those findings “did not indicate that surgery plus chemotherapy was superior to chemotherapy alone,” investigators concluded.

However, several factors in GOG-0213, including longer-than-expected survival times and substantial platinum sensitivity among women in the trial, could have diluted an independent surgical effect, they said.

Dr. Coleman reported disclosures related to several pharmaceutical companies, including Agenus, AstraZeneca, Clovis, GamaMabs, Genmab, Janssen, Medivation, Merck, Regeneron, Roche/Genentech, OncoQuest, and Tesaro.

PHILADELPHIA – The results of the first randomized prospective trial of an anticoagulation strategy versus standard dual antiplatelet (DAPT) therapy for patients undergoing transcatheter aortic valve replacement (TAVR) show that routine anticoagulation is not suitable for all comers in a high-risk population.

In the main GALILEO trial of elderly patients after TAVR, those who received an investigational anticoagulation strategy with the direct factor Xa inhibitor rivaroxaban (Xarelto; Bayer/Janssen) had worse survival and more thromboembolic and bleeding events than patients who received standard DAPT.

However, in the GALILEO 4D substudy of patients who underwent four-dimensional computed tomography (4DCT) randomized to the two therapies, those in the rivaroxaban arm were less likely to show subclinical leaflet motion abnormalities and leaflet thickening.

Preliminary results from GALILEO were disclosed in an October 3, 2018, “Dear Healthcare Professional” letter from Bayer, and the trial was stopped after a median of 17 months due to safety concerns.

The full data analysis from GALILEO as well as the results from GALILEO 4D were presented at the American Heart Association scientific sessions to coincide with their publication on Nov. 16, 2019, in the New England Journal of Medicine.

The takeaway message is that, despite the positive imaging finding in GALILEO 4D, “there is no reason to give 10 mg rivaroxaban-based treatment routinely after TAVR in patients who don’t need anticoagulation anyhow,” lead author in the main GALILEO trial, George D. Dangas, MD, PhD, Mount Sinai Hospital, New York, said in an interview.

However, because rivaroxaban had an effect in reducing the clots on leaflets, he said, further investigation is required to determine the optimal therapeutic strategy after TAVR.

Similarly, the assigned discussant for GALILEO, Elaine Hylek, MD, of Boston University said in an interview that “we just don’t know right now what the overall added benefit of an oral anticoagulant would be in this high-risk patient population after having a TAVR.”

Ole De Backer, MD, PhD, of Rigshospitalet University Hospital, Copenhagen, lead author of the GALILEO 4D substudy, concluded that, although the rivaroxaban-based strategy was associated with fewer valve abnormalities in this analysis, those positive outcomes need to be taken in context with worse clinical outcomes in the main GALILEO trial.

GALILEO

Guidelines recommend DAPT after TAVR, but this advice is based on expert consensus or small studies, the GALILEO study authors noted. Several years ago, there were random case reports and then case series of patients who had undergone TAVR or surgical aortic valve replacement (SAVR) and developed clots around the valve, Dr. Dangas explained.

These developments coincided with the first available high-quality CT angiography images that captured valve abnormalities that had not been seen before.

In parallel, there were rare reports of stroke and transient ischemic attack (TIA) that may have been associated with TAVR or SAVR. This triggered a series of studies to investigate an anticoagulation strategy after TAVR.

From December 2015 to May 2018, GALILEO enrolled 1,644 patients at 136 sites in 16 countries who had undergone successful TAVR, and had no indication for an anticoagulant (e.g., no atrial fibrillation).

The patients had a mean age of 80.6 years (plus or minus 6.6 years) and 49.5% were female. The median time from TAVR to randomization was 2 days (range, 0-8 days).

Half were randomized to receive an antithrombotic strategy, rivaroxaban 10 mg once daily plus aspirin 75-100 mg once daily for the first 90 days followed by rivaroxaban alone. The other half received an antiplatelet-based strategy, aspirin 75-100 mg once daily plus clopidogrel 75 mg once daily for the first 90 days followed by aspirin alone.

In the intention-to-treat analysis, death or first thromboembolic event, the primary efficacy outcome, occurred in 105 patients in the rivaroxaban group and 78 patients in the antiplatelet group (hazard ratio, 1.35; 95% CI, 1.01-1.81; P = .04).

Major, disabling, or life-threatening bleeding, the primary safety outcome, occurred in 46 and 31 patients, respectively (HR, 1.50; P = .08).

A total of 64 deaths occurred in the rivaroxaban group and 38 in the antiplatelet group (HR, 1.69; 95% CI, 1.13-2.53).

The individuals who were enrolled in this study were 80 and older, Dr. Hylek pointed out. “The age in and of itself is an uncontested risk factor for everything, whether it be bleeding, embolic event, or obviously mortality.”

Although the dose was half that used to prevent stroke in patients with atrial fibrillation, perhaps a “twice-daily lower dose” might be the way to go, moving forward, she said.

Patients who did not have atrial fibrillation may have developed atrial fibrillation in the interim, and “you would have to change the dose of the rivaroxaban.”

Also, patients who may have been taking aspirin for 5 or 10 years and “survived” aspirin, who were then newly exposed to an anticoagulant, would be more likely to experience bleeding.

“I certainly wouldn’t close the door on novel anticoagulants,” she concluded. “There are still other drug trials that are out there with this TAVR population. We’ll wait for that,” and see if the results corroborate these findings.

The high-risk patients may turn out to be a potential niche group for drugs being developed to inhibit factor XIa, she speculated.

GALILEO 4D

However, despite the negative results of the overall GALILEO study, results from the substudy that used 4DCT to evaluate function of the bioprosthetic aortic valves suggested rivaroxaban may have potentially beneficial effects on valve function.

The results showed that patients on the rivaroxaban and aspirin regimen had lower rates of subclinical reduced leaflet motion and leaflet thickening than patients on the antiplatelet strategy, said Dr. De Backer, reporting on behalf of the GALILEO-4D investigators.

The substudy evaluated 205 patients who had 4DCT 90 days after TAVR. The primary substudy endpoint was at least one prosthetic valve leaflet with a grade 3 or higher motion reduction, which 2 of 97 patients in the rivaroxaban group had (2.1%) versus 11 of 101 in the antiplatelet group (10.9%, P = .01).

“This indicated an 80% greater reduction of the primary endpoint in the rivaroxaban arm,” Dr. De Backer said. The chief secondary endpoint, the proportion of patients with at least one thickened leaflet, was met by 12.4% of the rivaroxaban group and 32.4% of the antiplatelet arm, “a 60% significant reduction by rivaroxaban,” Dr. De Backer said.

However, when the 10 patients in each group who didn’t adhere to the study drug regimen were excluded, he said, “then we see no single patient had reduced leaflet motion of grade 3 or more in the rivaroxaban arm.”

Another takeaway from the substudy is the ineffectiveness of transthoracic echocardiography as opposed to 4DCT in TAVR patients. Echocardiography (ECG) failed to show any significant differences in the mean valve gradient between the treatment groups, Dr. De Backer said.

Eleven patients who didn’t have leaflet thickening (7.3%) and 7 patients who did (15.9%) showed an increase of 5 mm Hg or more in the mean valve gradient on echo. ECG also showed a similar increase in the mean valve gradient in 14 patients who had no to moderate reduced leaflet motion (grade 3 or lower, 7.7%) and in four patients (30.8) who had grade 3 or higher reduced leaflet motion.

“This basically confirms results from observational studies that transthoracic echocardiography is often not good enough to detect these phenomena,” Dr. De Backer said.

The percentages of substudy patients who had major clinical events – major bleeding, thromboembolic events, or death at 90 days – were each less than 3%, he said. “There were too few clinical events to permit any assessment of the impact of leaflet thickening or reduced leaflet motion on clinical outcomes,” he said.

That lack of clarity with regard to clinical events is one of the questions the study leaves unanswered, said discussant Victoria Delgado, MD, PhD, of Leiden University Medical Center in the Netherlands.

“With stroke or TIA, there are too few events to draw any conclusions,” she said of the substudy. “We don’t know when we need to use CT, when we need to evaluate these patients, or maybe when we should go for more advanced imaging techniques where we can see the biology of those changes in the leaflets.” Hopefully, she said, future studies provide those insights.

“CT can be more sensitive than ECG to see these subclinical changes,” she said, “but the open questions that we have are to see if there is a correlation between thrombosis rate on imaging versus the stroke rate.”

The substudy’s conclusion on ECG, however, has been borne out by previous retrospective studies, Dr. Delgado added.

Robert A. Harrington, MD, of Stanford Medicine, tried to put the seemingly conflicting findings of the main GALILEO study and the 4D substudy into context.

“There you have the disconnect between the mechanism and the clinical observation and those are sometimes difficult to reconcile because the assumption is that the mechanism leads to the clinical outcome.”

While the main study shows that routine anticoagulation after TAVR is not indicated, the findings raise questions about the risk of clots forming on bioprosthetic valves. “Yes, maybe there are clots forming on these valves, but maybe that’s not causing the bad clinical outcomes,” Dr. Harrington said.

The findings also raise questions about the use of newer anticoagulants to prevent stroke post TAVR, he said. “It appears that warfarin is better than the newer anticoagulants for reasons that aren’t entirely clear.”

Dr. Dangas, lead author of the main GALILEO trial, said the substudy results could help design future trials of even-lower doses of anticoagulation in a more selective group of TAVR patients.

“In order to decrease the clots, first of all you don’t need the full dose of anticoagulation; even a low dose may do the trick,” he said. Further investigations can evaluate the clinical significance of having a blood clot in the valve as an indication for anticoagulation versus antiplatelet therapy.

“Even though this obviously doesn’t mean you’re going to have a stroke in a year or two,” Dr. Dangas said, “could it perhaps mean that the valve is not going to have such a good durability later on?”

Perhaps future studies of anticoagulation in TAVR should concentrate on patients who actually have clotting in the valve, he said.

The trial was supported by Bayer and Janssen. Dr. Dangas reported receiving grants from Bayer during the conduct of the study, personal fees from Bayer and Janssen, grants and personal fees from Daiichi-Sankyo, and “other” funding from Medtronic outside the submitted work. Dr. De Backer reported receiving grants from Bayer during the conduct of the study and personal fees from Abbott and Boston Scientific outside the submitted work.

The full data analysis from GALILEO as well as the results from GALILEO 4D were presented at the American Heart Association scientific sessions to coincide with their publication on Nov. 16, 2019, in the New England Journal of Medicine.

The takeaway message is that, despite the positive imaging finding in GALILEO 4D, “there is no reason to give 10 mg rivaroxaban-based treatment routinely after TAVR in patients who don’t need anticoagulation anyhow,” lead author in the main GALILEO trial, George D. Dangas, MD, PhD, Mount Sinai Hospital, New York, said in an interview.

However, because rivaroxaban had an effect in reducing the clots on leaflets, he said, further investigation is required to determine the optimal therapeutic strategy after TAVR.

Similarly, the assigned discussant for GALILEO, Elaine Hylek, MD, of Boston University said in an interview that “we just don’t know right now what the overall added benefit of an oral anticoagulant would be in this high-risk patient population after having a TAVR.”

Ole De Backer, MD, PhD, of Rigshospitalet University Hospital, Copenhagen, lead author of the GALILEO 4D substudy, concluded that, although the rivaroxaban-based strategy was associated with fewer valve abnormalities in this analysis, those positive outcomes need to be taken in context with worse clinical outcomes in the main GALILEO trial.

GALILEO

Guidelines recommend DAPT after TAVR, but this advice is based on expert consensus or small studies, the GALILEO study authors noted. Several years ago, there were random case reports and then case series of patients who had undergone TAVR or surgical aortic valve replacement (SAVR) and developed clots around the valve, Dr. Dangas explained.

These developments coincided with the first available high-quality CT angiography images that captured valve abnormalities that had not been seen before.

In parallel, there were rare reports of stroke and transient ischemic attack (TIA) that may have been associated with TAVR or SAVR. This triggered a series of studies to investigate an anticoagulation strategy after TAVR.

From December 2015 to May 2018, GALILEO enrolled 1,644 patients at 136 sites in 16 countries who had undergone successful TAVR, and had no indication for an anticoagulant (e.g., no atrial fibrillation).

The patients had a mean age of 80.6 years (plus or minus 6.6 years) and 49.5% were female. The median time from TAVR to randomization was 2 days (range, 0-8 days).

Half were randomized to receive an antithrombotic strategy, rivaroxaban 10 mg once daily plus aspirin 75-100 mg once daily for the first 90 days followed by rivaroxaban alone. The other half received an antiplatelet-based strategy, aspirin 75-100 mg once daily plus clopidogrel 75 mg once daily for the first 90 days followed by aspirin alone.

In the intention-to-treat analysis, death or first thromboembolic event, the primary efficacy outcome, occurred in 105 patients in the rivaroxaban group and 78 patients in the antiplatelet group (hazard ratio, 1.35; 95% CI, 1.01-1.81; P = .04).

Major, disabling, or life-threatening bleeding, the primary safety outcome, occurred in 46 and 31 patients, respectively (HR, 1.50; P = .08).

A total of 64 deaths occurred in the rivaroxaban group and 38 in the antiplatelet group (HR, 1.69; 95% CI, 1.13-2.53).

The individuals who were enrolled in this study were 80 and older, Dr. Hylek pointed out. “The age in and of itself is an uncontested risk factor for everything, whether it be bleeding, embolic event, or obviously mortality.”

Although the dose was half that used to prevent stroke in patients with atrial fibrillation, perhaps a “twice-daily lower dose” might be the way to go, moving forward, she said.

Patients who did not have atrial fibrillation may have developed atrial fibrillation in the interim, and “you would have to change the dose of the rivaroxaban.”

Also, patients who may have been taking aspirin for 5 or 10 years and “survived” aspirin, who were then newly exposed to an anticoagulant, would be more likely to experience bleeding.

“I certainly wouldn’t close the door on novel anticoagulants,” she concluded. “There are still other drug trials that are out there with this TAVR population. We’ll wait for that,” and see if the results corroborate these findings.

The high-risk patients may turn out to be a potential niche group for drugs being developed to inhibit factor XIa, she speculated.

GALILEO 4D

However, despite the negative results of the overall GALILEO study, results from the substudy that used 4DCT to evaluate function of the bioprosthetic aortic valves suggested rivaroxaban may have potentially beneficial effects on valve function.

The results showed that patients on the rivaroxaban and aspirin regimen had lower rates of subclinical reduced leaflet motion and leaflet thickening than patients on the antiplatelet strategy, said Dr. De Backer, reporting on behalf of the GALILEO-4D investigators.

The substudy evaluated 205 patients who had 4DCT 90 days after TAVR. The primary substudy endpoint was at least one prosthetic valve leaflet with a grade 3 or higher motion reduction, which 2 of 97 patients in the rivaroxaban group had (2.1%) versus 11 of 101 in the antiplatelet group (10.9%, P = .01).

“This indicated an 80% greater reduction of the primary endpoint in the rivaroxaban arm,” Dr. De Backer said. The chief secondary endpoint, the proportion of patients with at least one thickened leaflet, was met by 12.4% of the rivaroxaban group and 32.4% of the antiplatelet arm, “a 60% significant reduction by rivaroxaban,” Dr. De Backer said.

However, when the 10 patients in each group who didn’t adhere to the study drug regimen were excluded, he said, “then we see no single patient had reduced leaflet motion of grade 3 or more in the rivaroxaban arm.”

Another takeaway from the substudy is the ineffectiveness of transthoracic echocardiography as opposed to 4DCT in TAVR patients. Echocardiography (ECG) failed to show any significant differences in the mean valve gradient between the treatment groups, Dr. De Backer said.

Eleven patients who didn’t have leaflet thickening (7.3%) and 7 patients who did (15.9%) showed an increase of 5 mm Hg or more in the mean valve gradient on echo. ECG also showed a similar increase in the mean valve gradient in 14 patients who had no to moderate reduced leaflet motion (grade 3 or lower, 7.7%) and in four patients (30.8) who had grade 3 or higher reduced leaflet motion.

“This basically confirms results from observational studies that transthoracic echocardiography is often not good enough to detect these phenomena,” Dr. De Backer said.

The percentages of substudy patients who had major clinical events – major bleeding, thromboembolic events, or death at 90 days – were each less than 3%, he said. “There were too few clinical events to permit any assessment of the impact of leaflet thickening or reduced leaflet motion on clinical outcomes,” he said.

That lack of clarity with regard to clinical events is one of the questions the study leaves unanswered, said discussant Victoria Delgado, MD, PhD, of Leiden University Medical Center in the Netherlands.

“With stroke or TIA, there are too few events to draw any conclusions,” she said of the substudy. “We don’t know when we need to use CT, when we need to evaluate these patients, or maybe when we should go for more advanced imaging techniques where we can see the biology of those changes in the leaflets.” Hopefully, she said, future studies provide those insights.

“CT can be more sensitive than ECG to see these subclinical changes,” she said, “but the open questions that we have are to see if there is a correlation between thrombosis rate on imaging versus the stroke rate.”

The substudy’s conclusion on ECG, however, has been borne out by previous retrospective studies, Dr. Delgado added.

Robert A. Harrington, MD, of Stanford Medicine, tried to put the seemingly conflicting findings of the main GALILEO study and the 4D substudy into context.

“There you have the disconnect between the mechanism and the clinical observation and those are sometimes difficult to reconcile because the assumption is that the mechanism leads to the clinical outcome.”

While the main study shows that routine anticoagulation after TAVR is not indicated, the findings raise questions about the risk of clots forming on bioprosthetic valves. “Yes, maybe there are clots forming on these valves, but maybe that’s not causing the bad clinical outcomes,” Dr. Harrington said.

The findings also raise questions about the use of newer anticoagulants to prevent stroke post TAVR, he said. “It appears that warfarin is better than the newer anticoagulants for reasons that aren’t entirely clear.”

Dr. Dangas, lead author of the main GALILEO trial, said the substudy results could help design future trials of even-lower doses of anticoagulation in a more selective group of TAVR patients.

“In order to decrease the clots, first of all you don’t need the full dose of anticoagulation; even a low dose may do the trick,” he said. Further investigations can evaluate the clinical significance of having a blood clot in the valve as an indication for anticoagulation versus antiplatelet therapy.

“Even though this obviously doesn’t mean you’re going to have a stroke in a year or two,” Dr. Dangas said, “could it perhaps mean that the valve is not going to have such a good durability later on?”

Perhaps future studies of anticoagulation in TAVR should concentrate on patients who actually have clotting in the valve, he said.

The trial was supported by Bayer and Janssen. Dr. Dangas reported receiving grants from Bayer during the conduct of the study, personal fees from Bayer and Janssen, grants and personal fees from Daiichi-Sankyo, and “other” funding from Medtronic outside the submitted work. Dr. De Backer reported receiving grants from Bayer during the conduct of the study and personal fees from Abbott and Boston Scientific outside the submitted work.

SAN ANTONIO – Although there has been a general decline in transfusion-related anaphylaxis and acute infections over time among hospitalized older adults in the United States, incidence rates for both transfusion-related acute lung injury and transfusion-associated circulatory overload have risen over the last decade, according to researchers from the Food and Drug Administration.

Mikhail Menis, PharmD, an epidemiologist at the FDA Center for Biologics Evaluation and Research (CBER) and colleagues queried large Medicare databases to assess trends in transfusion-related adverse events among adults aged 65 years and older.

The investigators saw “substantially higher risk of all outcomes among immunocompromised beneficiaries, which could be related to higher blood use of all blood components, especially platelets, underlying conditions such as malignancies, and treatments such as chemotherapy or radiation, which need further investigation,” Dr. Menis said at the annual meeting of AABB, the group formerly known as the American Association of Blood Banks.

He reported data from a series of studies on four categories of transfusion-related events that may be life-threatening or fatal: transfusion-related anaphylaxis (TRA), transfusion-related acute lung injury (TRALI), transfusion-associated circulatory overload (TACO), and acute infection following transfusion (AIFT).

For each type of event, the researchers looked at overall incidence and the incidence by immune status, calendar year, blood components transfused, number of units transfused, age, sex, and race.
 

Anaphylaxis (TRA)

TRA may be caused by preformed immunoglobin E (IgE) antibodies to proteins in the plasma in transfused blood products or by preformed IgA antibodies in patients who are likely IgA deficient, Dr. Menis said.

The overall incidence of TRA among 8,833,817 inpatient transfusions stays for elderly beneficiaries from 2012 through 2018 was 7.1 per 100,000 stays. The rate was higher for immunocompromised patients, at 9.6, than it was among nonimmunocompromised patients, at 6.5.

The rates varied by every subgroup measured except immune status. Annual rates showed a downward trend, from 8.7 per 100,000 in 2012, to 5.1 in 2017 and 6.4 in 2018. The decline in occurrence may be caused by a decline in inpatient blood utilization during the study period, particularly among immunocompromised patients.

TRA rates increased with five or more units transfused. The risk was significantly reduced in the oldest group of patients versus the youngest (P less than .001), which supports the immune-based mechanism of action of anaphylaxis, Dr. Menis said.

They also found that TRA rates were substantially higher among patients who had received platelet and/or plasma transfusions, compared with patients who received only red blood cells (RBCs).

Additionally, risk for TRA was significantly higher among men than it was among women (9.3 vs. 5.4) and among white versus nonwhite patients (7.8 vs. 3.8).

The evidence suggested TRA cases are likely to be severe in this population, with inpatient mortality of 7.1%, and hospital stays of 7 days or longer in about 58% of cases, indicating the importance of TRA prevention, Dr. Menis said.

The investigators plan to perform multivariate regression analyses to assess potential risk factors, including underlying comorbidities and health histories for TRA occurrence for both the overall population and by immune status.
 

Acute lung injury (TRALI)

TRALI is a rare but serious adverse event, a clinical syndrome with onset within 6 hours of transfusion that presents as acute hypoxemia, respiratory distress, and noncardiogenic pulmonary edema.

Among 17,771,193 total inpatient transfusion stays, the overall incidence of TRALI was 33.2 per 100,000. The rate was 55.9 for immunocompromised patients versus 28.4 for nonimmunocompromised patients. The rate ratio was 2.0 (P less than .001).

The difference by immune status may be caused by higher blood utilizations with more units transfused per stay among immunocompromised patients, a higher incidence of prior transfusions among these patients, higher use of irradiated blood components that may lead to accumulation of proinflammatory mediators in blood products during storage, or underlying comorbidities.

The overall rate increased from 14.3 in 2007 to 56.4 in 2018. The rates increased proportionally among both immunocompromised and nonimmunocompromised patients.

As with TRA, the incidence of TRALI was higher in patients with five or more units transfused, while the incidence declined with age, likely caused by declining blood use and age-related changes in neutrophil function, Dr. Menis said.

TRALI rates were slightly higher among men than among women, as well as higher among white patients than among nonwhite patients.

Overall, TRALI rates were higher for patients who received platelets either alone or in combination with RBCs and/or plasma. The highest rates were among patients who received RBCs, plasma and platelets.

Dr. Menis called for studies to determine what effects the processing and storage of blood components may have on TRALI occurrence; he and his colleagues also are planning regression analyses to assess potential risk factors for this complication.
 

Circulatory overload (TACO)

TACO is one of the leading reported causes of transfusion-related fatalities in the U.S., with onset usually occurring within 6 hours of transfusion, presenting as acute respiratory distress with dyspnea, orthopnea, increased blood pressure, and cardiogenic pulmonary edema.

The overall incidence of TACO among hospitalized patients aged 65 years and older from 2011 through 2018 was 86.3 per 100,000 stays. The incidences were 128.3 in immunocompromised and 76.0 in nonimmunocompromised patients. The rate ratio for TACO in immunocompromised versus nonimmunocompromised patients was 1.70 (P less than .001).

Overall incidence rates of TACO rose from 62 per 100,000 stays in 2011 to 119.8 in 2018. As with other adverse events, incident rates rose with the number of units transfused.

Rates of TACO were significantly higher among women than they were among men (94.6 vs. 75.9 per 100,000; P less than .001), which could be caused by the higher mean age of women and/or a lower tolerance for increased blood volume from transfusion.

The study results also suggested that TACO and TRALI may coexist, based on evidence that 3.5% of all TACO stays also had diagnostic codes for TRALI. The frequency of co-occurrence of these two adverse events also increased over time, which may be caused by improved awareness, Dr. Menis said.
 

Infections (AIFT)

Acute infections following transfusion can lead to prolonged hospitalizations, sepsis, septic shock, and death. Those most at risk include elderly and immunocompromised patients because of high utilization of blood products, comorbidities, and decreased immune function.

Among 8,833,817 stays, the overall rate per 100,000 stays was 2.1. The rate for immunocompromised patients was 5.4, compared with 1.2 for nonimmunocompromised patients, for a rate ratio of 4.4 (P less than .001).

The incidence rate declined significantly (P = .03) over the study period, with the 3 latest years having the lowest rates.

Rates increased substantially among immunocompromised patients by the number of units transfused, but remained relatively stable among nonimmunocompromised patients.

Infection rates declined with age, from 2.7 per 100,000 stays for patients aged 65-68 years to 1.2 per 100,000 for those aged 85 years and older.

As with other adverse events, AIFT rates were likely related to the blood components transfused, with substantially higher rates for stays during which platelets were transfused either alone or with RBCs, compared with RBCs alone. This could be caused by the room-temperature storage of platelets and higher number of platelets units transfused, compared with RBCs alone, especially among immunocompromised patients.

In all, 51.9% of AIFT cases also had sepsis noted in the medical record, indicating high severity and emphasizing the importance of AIFT prevention, Dr. Menis said.

The studies were funded by the FDA, and Dr. Menis is an FDA employee. He reported having no conflicts of interest.

Infection rates declined with age, from 2.7 per 100,000 stays for patients aged 65-68 years to 1.2 per 100,000 for those aged 85 years and older.

As with other adverse events, AIFT rates were likely related to the blood components transfused, with substantially higher rates for stays during which platelets were transfused either alone or with RBCs, compared with RBCs alone. This could be caused by the room-temperature storage of platelets and higher number of platelets units transfused, compared with RBCs alone, especially among immunocompromised patients.

In all, 51.9% of AIFT cases also had sepsis noted in the medical record, indicating high severity and emphasizing the importance of AIFT prevention, Dr. Menis said.

The studies were funded by the FDA, and Dr. Menis is an FDA employee. He reported having no conflicts of interest.

VANCOUVER – Two new randomized trials demonstrate that pain following minimally invasive gynecologic surgery can be successfully managed using reduced opioid prescriptions.

In each case, patients were randomized to receive higher or lower numbers of oxycodone tablets. In both trials, the lower amount was five 5-mg oxycodone tablets. The work should reassure surgeons who wish to change their prescribing patterns, but may worry about patient dissatisfaction, at least in the context of prolapse repair and benign minor gynecologic laparoscopy, which were the focus of the two studies.

The ob.gyn. literature cites rates of 4%-6% of persistent opioid use after surgery on opioid-naive patients, and that’s a risk that needs to be addressed. “If we look at this as a risk factor of our surgical process, this is much higher than any other risk in patients undergoing surgery, and it’s not something we routinely talk to patients about,” Kari Plewniak, MD, an ob.gyn. at Montefiore Medical Center, New York, said during her presentation on pain control during benign gynecologic laparoscopy at the meeting sponsored by AAGL.

The trials provide some welcome guidance. “They provide pretty concrete guidelines with strong evidence of safety, so this is really helpful,” said Sean Dowdy, MD, chair of gynecologic oncology at Mayo Clinic in Rochester, Minn., while speaking as a discussant for the presentations.

Emily Davidson, MD, and associates at the Cleveland Clinic conducted a single-institution, noninferiority trial of standard- versus reduced-prescription opioids in 116 women undergoing prolapse repair. Half were randomized to receive 28 tablets of 5 mg oxycodone (routine arm) and half were prescribed just 5 tablets (reduced arm). All patients also received multimodal pain therapy featuring acetaminophen and ibuprofen. The mean age of patients was 62 years, 91% were white, and 84% were post menopausal. The most common surgery was hysterectomy combined with native tissue repair (60.2%), followed by vaginal colpopexy (15.3%), hysteropexy (15.3%), and sacrocolpopexy (9.3%).

At their postsurgical visit, patients were asked about their satisfaction with their postoperative pain management; 93% in the reduced arm reported that they were very satisfied or somewhat satisfied, as did 93% in the routine arm, which met the standard for noninferiority with a 15% margin. About 15% of patients in the reduced arm used more opioids than originally prescribed, compared with 2% of patients in the routine arm (P less than .01). The reduced arm had an average of 4 unused opioid tablets, compared with 26 in the routine arm. On average, the reduced arm used one tablet, compared with three in the routine arm (P = .03).

The researchers suggested that clinicians should consider prescribing 5-10 tablets for most patients, and all patients should receive multimodal pain management.

The noninferiority nature of the design was welcome, according to Dr. Dowdy. “I think we need to do more noninferiority trial designs because it allows us to make more observations about other parts of the value equation, so if we have two interventions that are equivalent, we can pick the one that has the best patient experience and the lowest cost, so it simplifies a lot of our management.”

The other study, conducted at Montefiore Medical Center, set out to see if a similar regimen of 5 5-mg oxycodone tablets, combined with acetaminophen and ibuprofen, could adequately manage postoperative pain after minor benign gynecologic laparoscopy (excluding hysterectomy), compared with a 10-tablet regimen. All patients received 25 tablets of 600 mg ibuprofen (1 tablet every 6 hours or as needed), plus 50 tablets of 250 mg acetaminophen (1-2 tablets every 6 hours or as needed).

The median number of opioid tablets taken was 2.0 in the 5-tablet group and 2.5 in the 10-tablet group; 32% and 28% took no tablets, and 68% and 65% took three or fewer tablets in the respective groups. The median number of leftover opioid tablets was 3 in the 5-tablet group and 8 in the 10-tablet group, reported Dr. Plewniak.

The studies are a good first step, but more is needed, according to Dr. Dowdy. It’s important to begin looking at more-challenging patient groups, such as those who are not opioid naive, as well as patients taking buprenorphine. “That creates some unique challenges with postoperative pain management,” he said.

VANCOUVER – Follow-up oncologic data from the UTERUS-11 trial shows advantages to surgical staging over clinical staging in stage IIB-IVA cervical cancer, with little apparent risk.

Compared with clinical staging using CT, laparoscopic staging led to an improvement in cancer-specific survival, with no delays in treatment or increases in toxicity. It also prompted surgical up-staging and led to treatment changes in 33% of cases. There was no difference in overall survival, but progression-free survival trended towards better outcomes in the surgical-staging group.

The new study presents 5-year follow-up data from patients randomly assigned to surgical (n = 121) or clinical staging (n = 114). The original study, published in 2017 (Oncology. 2017;92[4]:213-20), reported that 33% of surgical-staging patients in the surgical staging were up-staged as a result, compared with 6% who were revealed to have positive paraaortic lymph nodes through a CT-guided core biopsy after suspicious CT results. After a median follow-up of 90 months in both arms, overall survival was similar between the two groups, and progression-free survival trended towards an improvement in the surgical-staging group (P = .088). Cancer-specific survival was better in the surgical-staging arm, compared with clinical staging (P=.028), Audrey Tsunoda, MD, PhD, reported.

Surgical staging didn’t impact the toxicity profile, said Dr. Tsunoda, a surgical oncologist focused in gynecologic cancer surgery who practices at Hospital Erasto Gaertner in Curitiba, Brazil.

The mean time to initiation of chemoradiotherapy following surgery was 14 days (range, 7-21 days) after surgery: 64% had intensity-modulated radiotherapy and 36% had three-dimensional radiotherapy. There were no grade 5 toxicities during chemoradiotherapy and both groups had similar gastrointestinal and genitourinary toxicity profiles. About 97% of the surgical staging procedures were conducted laparoscopically. Two patients had a blood loss of more than 500 cc, and two had a delay to primary chemoradiotherapy (4 days and 5 days). One patient had to be converted to an open approach because of obesity and severe adhesions, and there was no intraoperative mortality.

Previous retrospective studies examining surgical staging in these patients led to confusion and disagreements among guidelines. Surgical staging is clearly associated with increased up-staging, but the oncologic benefit is uncertain. The LiLACS study attempted to address the question with prospective data, but failed to accrue enough patients and was later abandoned. That leaves the UTERUS-11 study, the initial results of which were published in 2017, as the first prospective study to examine the benefit of surgical staging.

The new follow-up results suggest a benefit to surgical staging, but they leave an important question unanswered, according to Lois Ramondetta, MD, professor of gynecologic oncology at the University of Texas MD Anderson Cancer Center, Houston, who served as a discussant at the meeting sponsored by AAGL. “Paraaortic lymph node status does connect to clinical benefit, but the question is really [whether] the removal of the lymph nodes accounts for the benefit, or is the identification of them and the change in treatment plan responsible? [If the latter is the case], a PET scan would have done a better job,” said Dr. Ramondetta. “The question remains unanswered, but I think this was huge progress in trying to answer it. Future studies need to incorporate a PET scan.”

SAN FRANCISCO – Volume matters when it comes to mitral valve repair/replacement for primary mitral regurgitation. The more cases a physician and hospital do, the better the outcomes, according to a review of 55,311 cases in the Society of Thoracic Surgeons Adult Cardiac Surgery Database.

Investigators “found a clear inflection point at approximately 75 cases” for hospitals and 35 cases for individual surgeons when the curves for successful mitral repair and 30-day operative mortality start to level out. Nationwide, 148 hospitals (14%) in the analysis did 75 or more mitral cases a year, and 303 surgeons (13%) did at least 35.

Lead investigator Vinay Badhwar, MD, professor and chair of cardiovascular and thoracic surgery at West Virginia University, Morgantown, estimated that about 90% of Americans have access to a regional hospital that does at least 25 mitral procedures annually, and about 82% can use a regional hospital that does at least 40. Meanwhile, the rate of mitral valve repair for primary mitral regurgitation was 81% (44,692/55,311) in the study, up from about 60% a decade ago.

“We are getting there; we are getting better,” Dr. Badhwar said at the Transcatheter Cardiovascular Therapeutics annual meeting. By defining volume cut points, he said the findings could be useful in future guidelines to steer referrals to higher-volume centers.

“We really needed these data, because we’ve had so many other pieces pointing to the volume repair rates and technical success, which clearly is related to volume. Now we have the outcome data we’ve been looking for; this ties it together. There really is an impact on patient outcomes,” Robert Bonow, MD, a professor of cardiology at Northwestern University, Chicago, commented.

The team divided annual case volume into quartiles. The lowest hospital quartile did fewer than 11 cases a year, and the highest more than 46. The lowest-quartile surgeons did fewer than 6 cases a year, and the highest more than 20. Lowest-quartile surgeons and hospitals, versus the highest, had higher operative mortality and 30-day morbidity and mortality, and lower 1-year survival.

Patients in the lowest quartile were also more likely to be black or Hispanic (14.8% versus 10.2%); have no insurance (4.0% versus 2.4%); and more severe symptom presentation (31.9% versus 23.8% class III or IV heart failure). The differences were highly statistically significant.

Study moderator Ajay Kirtane, MD, an interventional cardiologist and associate professor of medicine at Columbia University, New York, said there’s a role for advocacy to get more people to high-volume centers. “Just because you live in an area that has a good program doesn’t mean that you are actually going to get referred to that program. We find a lot that it’s advocacy that is important,” especially with the disparities noted in the study. “Not everybody has an advocate who says, ‘Don’t do it here; do it someplace else,’ ” he said at the meeting sponsored by the Cardiovascular Research Foundation.

And not everyone has an advocate to get them to the right surgeon, even if they get to the right program. “There are cardiac procedures that most surgeons can do well. Mitral valve surgery is one of those that should be super specialized,” said cardiothoracic surgeon Michael Mack, MD, director of the cardiovascular service line at Baylor Scott and White Health System, Dallas.

No industry funding was reported. Dr. Badhwar had no relevant disclosures.

The team divided annual case volume into quartiles. The lowest hospital quartile did fewer than 11 cases a year, and the highest more than 46. The lowest-quartile surgeons did fewer than 6 cases a year, and the highest more than 20. Lowest-quartile surgeons and hospitals, versus the highest, had higher operative mortality and 30-day morbidity and mortality, and lower 1-year survival.

Patients in the lowest quartile were also more likely to be black or Hispanic (14.8% versus 10.2%); have no insurance (4.0% versus 2.4%); and more severe symptom presentation (31.9% versus 23.8% class III or IV heart failure). The differences were highly statistically significant.

Study moderator Ajay Kirtane, MD, an interventional cardiologist and associate professor of medicine at Columbia University, New York, said there’s a role for advocacy to get more people to high-volume centers. “Just because you live in an area that has a good program doesn’t mean that you are actually going to get referred to that program. We find a lot that it’s advocacy that is important,” especially with the disparities noted in the study. “Not everybody has an advocate who says, ‘Don’t do it here; do it someplace else,’ ” he said at the meeting sponsored by the Cardiovascular Research Foundation.

And not everyone has an advocate to get them to the right surgeon, even if they get to the right program. “There are cardiac procedures that most surgeons can do well. Mitral valve surgery is one of those that should be super specialized,” said cardiothoracic surgeon Michael Mack, MD, director of the cardiovascular service line at Baylor Scott and White Health System, Dallas.

PHILADELPHIA – Women who underwent either hysterectomy or myomectomy had similar short-term outcomes between 6 weeks and 12 weeks after surgery despite different baseline characteristics, according to recent results from the COMPARE-UF study presented at the annual meeting of the American Society for Reproductive Medicine.

“Both hysterectomy and myomectomy can substantially improve women’s quality of life scores and substantially reduce symptom severity,” reported Wanda K. Nicholson, MD, MPH, lead investigator for COMPARE-UF and professor of general obstetrics and gynecology at the University of North Carolina at Chapel Hill.

Researchers included 1,295 women in the COMPARE-UF study who were at least 30 years old, not attempting pregnancy, and undergoing hysterectomy or myomectomy for treatment of fibroids. Overall, 727 patients underwent hysterectomy, and 568 patients underwent myomectomy.

The researchers measured QoL and symptom severity using the Uterine Fibroid Scale-QoL, the EQ-5D, and Visual Analog Scale (VAS). The UFS-QoL contained subscales for concern, activities, energy and mood, control, self-consciousness, and sexual function, while the EQ-5D had subscales for mobility, self-care, usual activities, pain or discomfort, and anxiety or depression.

After surgery, UFS-QoL overall scores were similar in both hysterectomy and myomectomy groups between 6 weeks and 12 weeks (77 vs. 76), but there was less postsurgery symptom severity in the hysterectomy group over the same time period (16 vs. 20; P less than .05). However, both groups had a significant improvement in overall UFS-QoL post surgery (hysterectomy, 31; myomectomy, 30) and in UFS-QoL symptom severity (hysterectomy, 41; myomectomy, 37), Dr. Nicholson noted. EQ-5D VAS scores also were similar in both hysterectomy and myomectomy groups after treatment (82 vs. 79), and showed a 10.9 score improvement in hysterectomy patients and an 8.6 score improvement in myomectomy patients.

“This is really important, because it shows that, regardless of which procedure that you’ve chosen, at least at short-term follow up, it appears that you will have improvement in quality of life,” she said.

When researchers analyzed the UFS-QoL subscale scores, they found patients who underwent abdominal myomectomy scored better than abdominal hysterectomy on the activities subscale (79 vs. 72; P equals .01) and energy/mood subscale (82 vs. 75; P equals .03). In examining minimally invasive procedures, Dr. Nicholson and colleagues found higher improvements in health-related QoL scores among patients undergoing minimally invasive hysterectomy (45-80 vs. 45 vs. 75), and these patients also had lower symptom severity, compared with patients who underwent myomectomy (59-13 vs. 58-21).

“At least at the short-term follow-up, we think that some of that difference that we see in minimally invasive procedures vs. nonminimally invasive may be in part due to women’s perceptions or what their expectations are having minimally invasive surgery, and how they might feel in the short-term follow-up period,” said Dr. Nicholson.

These similar short-term outcomes occurred even though there were significant differences in baseline patient characteristics for the hysterectomy and myomectomy groups, with women undergoing hysterectomy being significantly younger (40 years) than patients undergoing hysterectomy (45 years). Differences also were significant between hysterectomy and myomectomy groups in the percentage of patients who were white (50% vs. 41%; P less than .01), African-American (38% vs. 41%; P less than .01) or other races (12% vs. 18%; P less than .01). There also were significant differences in baseline body mass index between hysterectomy (31 kg/m²) and myomectomy (29 kg/m²) groups.

Patients in both groups further differed in presurgery quality-of-life (QoL) scores.

Women in the hysterectomy group had lower presurgery overall QoL (44 vs. 50), greater symptom severity (60 vs. 52), and lower VAS (69 vs. 73) scores, compared with the myomectomy group (P less than .05). This difference continued in the UFS-QoL subscale scores, where women in the hysterectomy group had significantly lower scores in the concern (38 vs. 45), activities (46 vs. 52), energy/mood (45 vs. 51), control (48 vs. 52), self-consciousness (41 vs. 50), and sexual function (45 vs. 50) subscales, compared with women in the myomectomy group (P less than .05). The researchers used propensity scoring to adjust for baseline characteristics, and inverse propensity weighting to adjust for potential confounding in the multivariate analysis.

COMPARE-UF is funded by the Agency for Healthcare Research and Quality (AHRQ), Patient-Centered Outcomes Research Institute (PCORI), and the National Institutes of Health. Dr. Nicholson reported no relevant conflicts of interest.

SAN FRANCISCO – A “Best Case/Worst Case” (BCWC) framework tool has been adapted for use with geriatric trauma patients in the ICU, where it can help track a patient’s progress and enable better communication with patients and loved ones. The tool relies on a combination of graphics and text that surgeons update daily during rounds, and creates a longitudinal view of a patient’s trajectory during their stay in the ICU.

Andrei Malov/Thinkstock

The aim is to have surgeons incorporate story telling into care, by updating the best-case scenario in light of new clinical developments – for example, after a complication has arisen.

“Each day during rounds, the ICU team records important events on the graphic aid that change the patient’s course. The team draws a star to represent the best case, and a line to represent prognostic uncertainty. The attending trauma surgeon then uses the geriatric trauma outcome score, their knowledge of the health state of the patient, and their own clinical experience to tell a story about treatments, recovery, and outcomes if everything goes as well as we might hope. This story is written down in the best-case scenario box,” Christopher Zimmerman, MD, a general surgery resident at the University of Wisconsin–Madison, said during a presentation about the BCWC tool at the annual clinical congress of the American College of Surgeons

“We often like to talk to patients and their families [about best- and worst-case scenarios] anyway, but [the research team] have tried to formalize it,” said Tam Pham, MD, professor of surgery at the University of Washington, in an interview. Dr. Pham comoderated the session where the research was presented.

“When we’re able to communicate where the uncertainty is and where the boundaries are around the course of care and possible outcomes, we can build an alliance with patients and families that will be helpful when there is a big decision to make, say about a laparotomy for a perforated viscus,” said Dr. Zimmerman.

Dr. Zimmerman gave an example of a patient who came into the ICU after suffering multiple fractures from falling down a set of stairs. The team created an initial BCWC with a hoped-for best-case scenario. Later, the patient developed hypoxemic respiratory failure and had to be intubated overnight. “This event is recorded on the graphic, and her star representing the best case has changed position, the line representing uncertainty has shortened, and the contents of her best-case scenario has changed. Each day in rounds, this process is repeated,” said Dr. Zimmerman.

Palliative care physicians, education experts, and surgeons at the University of Wisconsin–Madison developed the tool in an effort to reduce unwanted care at the end of life, in the context of high-risk surgeries. The researchers adapted the tool to the trauma setting by gathering six focus groups of trauma practitioners at the University of Wisconsin; University of Texas, Dallas; and Oregon Health & Science University, Portland. They modified the tool after incorporating comments, and then iteratively modified it through tasks carried out in the ICU as part of a qualitative improvement initiative at the University of Wisconsin–Madison. They generated a change to the tool, implemented it in the ICU during subsequent rounds, then collected observations and field notes, then revised and repeated the process, streamlining it to fit into the ICU environment, according to Dr. Zimmerman.

The back side of the tool is available for family members to write important details about their loved ones, leading insight into the patient’s personality and desires, such as favorite music or affection for a family pet.

The work was supported by the National Institutes of Health. Dr. Zimmerman and Dr. Pham have no relevant financial disclosures.

SAN FRANCISCO – Opioids may not always be necessary following elective colorectal surgery. That’s the message coming from a retrospective study of medical records at the University of Massachusetts Medical Center, Worcester, which found that over half of patients never even filled out their prescription after colorectal surgery.

“We found that over half of the patients took no opioid pills after discharge, and 60% of the prescribed pills were left over,” said David Meyer, MD, during a presentation of the study at the annual clinical congress of the American College of Surgeons. Dr. Meyer is a surgical resident at the University of Massachusetts.

The team also used the results of their analysis to develop a guideline for the amount of opioid to prescribe following major colorectal surgery, with specific amounts of pills recommended based on the amount of opioid use during the last 24 hours of hospitalization.

“It shows a real interest in tailoring our postoperative care in pain management. They’re trying to find a way to hit a sweet spot to get patients the right amount of pain control,” said Jonathan Mitchem, MD, in an interview. Dr. Mitchem is an assistant professor at University of Missouri–Columbia, and comoderated the session where the research was presented.

The researchers performed a retrospective analysis of major elective colorectal procedures at their institution, including colectomy, rectal resection, and ostomy reversal. The analysis included 100 patients (55 female), with a mean age of 59 years. A total of 71% were opioid naive, meaning there was no evidence of an opioid prescription in the year prior to surgery. A total of 74% underwent a laparoscopic procedure, and 75% had a partial colectomy. The postoperative stay averaged 4.5 days.

The researchers converted in-hospital opioid use categories (IOUC) to equianalgesic 5-mg oxycodone pills (EOPs). In the last 24 hours before release, 53% of patients had no opioids at all (no IOUC, 0 EOPs), 25% received low amounts of opioids (low IOUC, 0.1-3.0 EOPs), and 22% high amounts (high IOUC, more than 3.1 EOPs). Overall, prescribed EOP was 17.5, and just 38% was consumed. These numbers were lowest in the no-IOUC group (15.7, 16%), followed by the low-IOUC group (16.0, 32%), and the high group (23.7, 79%; P less than .01).

The researchers then looked at the 85th percentile of EOPs for each group, and used that to develop a guideline for opioid prescription. For the no-IOUC group, they recommend 3 EOPs, for the low-IOUC group they recommend 12 EOPs, and for the high-IOUC group they recommend 30 EOPs.

The researchers examined various factors that might have influenced opioid use, correcting for whether the patient was opioid naive, case type, postoperative length of stay, and new ostomy creation. The only factor with a significant association for excessive opioid use was inflammatory bowel disease, which was linked to a nearly 900% increased risk of using more than the guideline amounts (adjusted odds ratio, 8.3; P less than .01; area under the curve, 0.85).

The study is limited by the fact that it was conducted at a single center, and that patient opioid use was self-reported. The guidelines need to be validated prospectively.

No funding information was disclosed. Dr. Meyer and Dr. Mitchem had no relevant financial disclosures.

The only factor with a significant association for excessive opioid use was inflammatory bowel disease, which was linked to a nearly 900% increased risk of using more than the guideline amounts (adjusted odds ratio, 8.3; P less than .01; area under the curve, 0.85).

The study is limited by the fact that it was conducted at a single center, and that patient opioid use was self-reported. The guidelines need to be validated prospectively.

SAN FRANCISCO – Opioids may not always be necessary following elective colorectal surgery. That’s the message coming from a retrospective study of medical records at the University of Massachusetts Medical Center, Worcester, which found that over half of patients never even filled out their prescription after colorectal surgery.

“We found that over half of the patients took no opioid pills after discharge, and 60% of the prescribed pills were left over,” said David Meyer, MD, during a presentation of the study at the annual clinical congress of the American College of Surgeons. Dr. Meyer is a surgical resident at the University of Massachusetts.

The team also used the results of their analysis to develop a guideline for the amount of opioid to prescribe following major colorectal surgery, with specific amounts of pills recommended based on the amount of opioid use during the last 24 hours of hospitalization.

“It shows a real interest in tailoring our postoperative care in pain management. They’re trying to find a way to hit a sweet spot to get patients the right amount of pain control,” said Jonathan Mitchem, MD, in an interview. Dr. Mitchem is an assistant professor at University of Missouri–Columbia, and comoderated the session where the research was presented.

The researchers performed a retrospective analysis of major elective colorectal procedures at their institution, including colectomy, rectal resection, and ostomy reversal. The analysis included 100 patients (55 female), with a mean age of 59 years. A total of 71% were opioid naive, meaning there was no evidence of an opioid prescription in the year prior to surgery. A total of 74% underwent a laparoscopic procedure, and 75% had a partial colectomy. The postoperative stay averaged 4.5 days.

The researchers converted in-hospital opioid use categories (IOUC) to equianalgesic 5-mg oxycodone pills (EOPs). In the last 24 hours before release, 53% of patients had no opioids at all (no IOUC, 0 EOPs), 25% received low amounts of opioids (low IOUC, 0.1-3.0 EOPs), and 22% high amounts (high IOUC, more than 3.1 EOPs). Overall, prescribed EOP was 17.5, and just 38% was consumed. These numbers were lowest in the no-IOUC group (15.7, 16%), followed by the low-IOUC group (16.0, 32%), and the high group (23.7, 79%; P less than .01).

The researchers then looked at the 85th percentile of EOPs for each group, and used that to develop a guideline for opioid prescription. For the no-IOUC group, they recommend 3 EOPs, for the low-IOUC group they recommend 12 EOPs, and for the high-IOUC group they recommend 30 EOPs.

SAN FRANCISCO – Chest tube placement and removal comes with a high error rate, with about one in five procedures going wrong, according to a prospective observational study conducted at 14 adult trauma centers.

“The sad part is, I don’t know if it was surprisingly high, but I’m glad somebody has taken the time to document it,” said Robert Sawyer, MD, professor of surgery at Western Michigan University, Kalamazoo, Mich., who comoderated the session at the annual clinical congress of the American College of Surgeons, where the study was presented.

The researchers examined error rates in both insertions and removals, and compared some of the practices and characteristics of trauma centers with unusually good or poor records. The work could begin to inform quality improvement initiatives. “That’s very parallel to where we were 20 or 25 years ago with central venous catheters. We used to put them in and thought it was never a problem, and then we started taking a close look at it and found out, yeah, there was a problem. We systematically made our procedures more consistent and had better outcomes. I think chest tubes is going to be ripe for that,” Dr. Sawyer said in an interview.

“In some ways we have been lying to ourselves. We acknowledge that trainees have a high rate of complications in chest tube insertion and removal, but we haven’t fixed it as a systematic problem. We’re behind in our work to reduce complications for this bedside procedure,” echoed the session’s other comoderator, Tam Pham, MD, professor of surgery at the University of Washington, Seattle, in an interview.

The researchers defined chest tube errors as anything that resulted in a need to manipulate, replace, or revise an existing tube; a worsening of the condition that the tube was intended to address; or complications that resulted in additional length of stay or interventions. A total of 381 chest tubes were placed in 273 patients over a 3-month period, about 55% by residents and about 28% by trauma attending physicians. Around 80% were traditional chest tubes, and most of the rest were Pigtail, with a very small fraction of Trocar chest tubes, according to a pie chart displayed by Michaela West, MD, a trauma surgeon at North Memorial Health, Robbinsdale, Minn., who presented the research.
