Factors influencing receipt and time to treatment of immunotherapy relative to chemotherapy in stage III and stage IV melanoma.

BACKGROUND: Immunotherapies have changed the landscape of late-stage melanoma; however, data evaluating timely access to immunotherapy are lacking. METHODS: A retrospective cohort study utilizing the National Cancer Database was conducted. Stage III and IV melanoma cases diagnosed between 2011 and 2018 that received systemic treatment with either immunotherapy or chemotherapy were included. Chemotherapy included BRAF/MEK inhibitors. Multivariable logistic regression models were utilized to evaluate factors associated with the likelihood of receiving immunotherapy as primary systemic treatment relative to chemotherapy; additionally, Cox proportional hazards models were utilized to incorporate time from diagnosis to primary systemic therapy into the analysis. RESULTS: The study population was comprised of 14,446 cases. The cohort included 12,053 (83.4%) immunotherapy and 2393 (16.6%) chemotherapy cases. In multivariable logistic regression analysis, factors significantly associated with immunotherapy receipt included population density, circle distance, year of diagnosis, Breslow thickness, and cancer stage. Immunotherapy timing was evaluated using multivariable Cox regression analysis. Minorities were less likely to receive timely immunotherapy than non-Hispanic Whites (HR 0.83, CI 0.74-0.93, p = 0.001). Patients at circle distances of 10-49 miles (HR 0.94, CI 0.89-0.99, p = 0.02) and ≥50 miles (HR 0.83, CI 0.77-0.90, p < 0.001) were less likely to receive timely immunotherapy. CONCLUSION: Patients traveling ≥10 miles and minorities have a decreased likelihood of receiving timely immunotherapy administration for primary systemic treatment. Future research is needed to identify what barriers and approaches can be leveraged to address these inequities.

Days Alive and Out of the Hospital After Heart Transplantation: A Retrospective Cohort Study.

OBJECTIVE: Evaluate days alive and out of the hospital (DAOH) as an outcome measure after orthotopic heart transplantation in patients with mechanical circulatory support (MCS) as a bridge to transplant compared to those patients without prior MCS. DESIGN: A retrospective observational study of adult patients who underwent cardiac transplantation between January 1, 2015, and January 1, 2020. The primary outcome was DAOH at 365 days (DAOH365) after an orthotopic heart transplant. A Poisson regression model was fitted to detect the association between independent variables and DAOH365. SETTING: An academic tertiary referral center. PARTICIPANTS: A total of 235 heart transplant patients were included-103 MCS as a bridge to transplant patients, and 132 direct orthotopic heart transplants without prior MCS. MEASUREMENTS AND MAIN RESULTS: The median DAOH365 for the entire cohort was 348 days (IQR 335.0-354.0). There was no difference in DAOH365 between the MCS patients and patients without MCS (347.0 days [IQR 336.0-353.0] v 348.0 days [IQR 334.0-354.0], p = 0.43). Multivariate analysis identified patients who underwent a transplant after the 2018 heart transplant allocation change, pretransplant pulmonary hypertension, and increased total ischemic time as predictors of reduced DAOH365. CONCLUSIONS: In this analysis of patients undergoing orthotopic heart transplantation, there was no significant difference in DAOH365 in patients with prior MCS as a bridge to transplant compared to those without MCS. Incorporating days alive and out of the hospital into the pre-transplant evaluation may improve understanding and conceptualization of the post-transplantation patient experience and aid in shared decision-making with clinicians.

Ethics Education in U.S. Allopathic Medical Schools: A National Survey of Medical School Deans and Ethics Course Directors.

AbstractPurpose: to characterize ethics course content, structure, resources, pedagogic methods, and opinions among academic administrators and course directors at U.S. medical schools. METHOD: An online questionnaire addressed to academic deans and ethics course directors identified by medical school websites was emailed to 157 Association of American Medical Colleges member medical schools in two successive waves in early 2022. Descriptive statistics were utilized to summarize responses. RESULTS: Representatives from 61 (39%) schools responded. Thirty-two (52%) respondents were course directors; 26 (43%) were deans of academic affairs, medical education, or curriculum; and 3 with other roles also completed the survey (5%). All 61 schools reported some form of formal ethics education during the first year of medical school, with most (n = 54, 89%) reporting a formal mandatory introductory course during preclinical education. Schools primarily utilized lecture and small-group teaching methods. Knowledge-based examinations, attendance, and participation were most commonly used for assessment. A large majority regarded ethics as equally or more important than other foundational courses, but fewer (n = 37, 60%) provided faculty training for teaching ethics. CONCLUSIONS: Despite a response rate of 39 percent, the authors conclude that medical schools include ethics in their curricula in small-group and lecture formats with heterogeneity regarding content taught. Preclinical curricular redesigns must innovate and implement best practices for ensuring sound delivery of ethics content in future curricula. Additional large-scale research is necessary to determine said best practices.

The Value of Pharmacogenomics for White and Indigenous Americans after Kidney Transplantation.

BACKGROUND: There is a paucity of evidence to inform the value of pharmacogenomic (PGx) results in patients after kidney transplant and how these results differ between Indigenous Americans and Whites. This study aims to identify the frequency of recommended medication changes based on PGx results and compare the pharmacogenomic (PGx) results and patients' perceptions of the findings between a cohort of Indigenous American and White kidney transplant recipients. METHODS: Thirty-one Indigenous Americans and fifty White kidney transplant recipients were studied prospectively. Genetic variants were identified using the OneOme RightMed PGx test of 27 genes. PGx pharmacist generated a report of the genetic variation and recommended changes. Pre- and post-qualitative patient surveys were obtained. RESULTS: White and Indigenous American subjects had a similar mean number of medications at the time of PGx testing (mean 13 (SD 4.5)). In the entire cohort, 53% received beta blockers, 30% received antidepressants, 16% anticoagulation, 47% pain medication, and 25% statin therapy. Drug-gene interactions that warranted a clinical action were present in 21.5% of patients. In 12.7%, monitoring was recommended. Compared to the Whites, the Indigenous American patients had more normal CYP2C19 (p = 0.012) and CYP2D6 (p = 0.012) activities. The Indigenous American patients had more normal CYP4F2 (p = 0.004) and lower VKORC (p = 0.041) activities, phenotypes for warfarin drug dosing, and efficacy compared to the Whites. SLC6A4, which affects antidepressant metabolism, showed statistical differences between the two cohorts (p = 0.017); specifically, SLC6A4 had reduced expression in 45% of the Indigenous American patients compared to 20% of the White patients. There was no significant difference in patient perception before and after PGx. CONCLUSIONS: Kidney transplant recipients had several drug-gene interactions that were clinically actionable; over one-third of patients were likely to benefit from changes in medications or drug doses based on the PGx results. The Indigenous American patients differed in the expression of drug-metabolizing enzymes and drug transporters from the White patients.

The influence of operating room temperature and humidity on surgical site infection: A multisite ACS-NSQIP analysis.

BACKGROUND: Literature evaluating intraoperative temperature/humidity and risk of surgical site infection (SSI) is lacking. METHODS: All operations at three centers reported to the ACS-NSQIP were reviewed (2016-2020); ambient intraoperative temperature (°F) and relative humidity (RH) were recorded in 15-min intervals. The primary endpoint was superficial SSI, which was evaluated with multi-level logistic regression. RESULTS: 14,519 operations were analyzed with 179 SSIs (1.2%). The lower/upper 10th percentiles for temperature and RH were 64.4/71.4 °F and 33.5/55.5% respectively. Low or high temperature carried no significant increased risk for SSI (Low °F OR = 0.95, 95% CI 0.51-1.77, P = 0.86; High °F OR = 1.13, 95% CI = 0.69-1.86, P = 0.63). This was also true for low and high RH (Low RH OR = 0.96, 95% CI 0.58-1.61, p = 0.88; High RH OR = 0.61, 95% CI = 0.33-1.14, P = 0.12). Analysis of combined temperature/humidity showed no increased risk for SSI. CONCLUSION: Significant deviations in intraoperative temperature/humidity are not associated with increased risk of SSI.

Human Trafficking Education: A Pilot Study of Integration into Medical School Curriculum.

OBJECTIVES: Few medical schools incorporate formal education on human trafficking (HT) and sex trafficking (ST) into their curriculum. Our objective was to develop, implement, and evaluate education on HT and ST in the first-year medical student curriculum. METHODS: The curriculum included a standardized patient (SP) experience and lecture. As part of their mandatory sexual health course, students interviewed an SP who presented with red flags for ST and then participated in a discussion led by a physician-facilitator in an observed small group setting. A multiple-choice survey to assess knowledge about HT and ST was developed and administered to students before and after the SP interview. RESULTS: Of the 50 first-year medical students, 29 (58%) participated in the survey. Compared with the students' baseline scores (according to the percentage of correct responses), scores after the educational intervention showed a significant increase in percentage correct on questions related to trafficking definition and scope (elder care, P = .01; landscaping, P = .03); victim identification (P < .001); referral to services (P < .001); legal issues (P = .01); and security (P < .001). On the basis of the feedback, a 2-hour lecture, which was adapted from the American Medical Women's Association-Physicians Against the Trafficking of Humans "Learn to Identify and Fight Trafficking" training, was presented the next year to all first-year medical students as part of their longitudinal clinical skills course and before the SP case. Curriculum objectives included learning trafficking definitions, victim/survivor identification, intersections with health care, the local impact of HT, and available resources. CONCLUSION: This curriculum fulfills course objectives and could be replicated at other institutions. Further evaluation of this pilot curriculum is necessary to evaluate its effectiveness.

Defining Biliary Hyperkinesia and the Role of Cholecystectomy.

BACKGROUND: Functional gallbladder disorder is most commonly defined by biliary colic and low ejection fraction (EF) on cholescintigraphy. Biliary hyperkinesia is a controversial type of functional gallbladder disorder, and its definition and the role of cholecystectomy in treating functional gallbladder disorder remains unclear. STUDY DESIGN: We conducted a retrospective review of patients who underwent cholecystokinin-stimulated cholescintigraphy and cholecystectomy at 3 Mayo Clinic sites between 2007 and 2020. Eligible patients were 18 years or older, presented with symptoms of biliary disease, had an EF greater than 50%, underwent cholecystectomy, and had no evidence of acute cholecystitis or cholelithiasis on imaging. We used receiver operating characteristics curve analysis to identify the optimal cutoff value that predicted symptom resolution within 30 days of cholecystectomy. RESULTS: A total of 2,929 cholecystokinin-stimulated cholescintigraphy scans were performed during the study period; the average EF was 67.5% and the median EF was 77%. Analyzing those with EFs greater than or equal to 50% yielded 1,596 patients with 141 (8.8%) going on to have cholecystectomy. No significant differences were found in age, sex, BMI, final pathology between patients with and without pain resolution. Using a cutoff EF of 81% was significantly associated with pain resolution after cholecystectomy (78.2% for EF greater than or equal to 81% vs 60.0% for EF less than 81%, p = 0.03). Chronic cholecystitis was found in 61.7% of the patients on final pathology. CONCLUSIONS: We determined that an EF cutoff of 81% is a reasonable upper limit of normal gallbladder EF. Patients with biliary symptoms and an EF greater than 81% but no evidence of biliary disease on ultrasound or scintigraphy can be classified as having biliary hyperkinesia. Based on our findings, we recommend cholecystectomy for this patient population.

The Impact of Patient Sex on Outcomes after Endovascular Treatment of Aortoiliac Occlusive Disease.

BACKGROUND: The aim of this study was to explore the effect of patient sex on short-term and long-term outcomes after endovascular treatment for aortoiliac occlusive disease (AIOD). METHODS: A multicenter retrospective analysis was performed on all patients who underwent iliac artery stenting for AIOD across the 3 participating sites from October 1, 2018 to September 21, 2021. Preoperative clinical, operative, and postoperative data were collected on a dedicated database. Demographics and outcomes were compared between male and female patients and the probability of freedom from amputation and freedom from target lesion reintervention were estimated with the Kaplan-Meier method. RESULTS: Of 574 patients, 346 (60%) were male and 228 (40%) were female. Mean follow-up was 12 months. Female patients were significantly older (69.2 ± 10.2 years vs. 67.8 ± 8.9 years, P = 0.025) and more likely to have Trans-Atlantic Inter-Society Consensus II D disease (P = 0.003). The female cohort had significantly less coronary artery disease (40% vs. 50%, P = 0.013), coronary stenting (14% vs. 21%, P = 0.039), and coronary artery bypass grafting (13% vs. 25%, P < 0.001) than the male cohort, as well as less statin use (69% vs. 80%, P = 0.004). There were no differences in stent type, concomitant open surgery, intraoperative events, or hospital length of stay. For 30-day postoperative complications, female patients had a significantly higher rate of thrombotic acute limb ischemia (2% vs. 0%, P = 0.01), while male patients had a higher rate of amputation (4% vs. 9%, P = 0.048). On mid-term outcomes, there was no difference in freedom from amputation or target lesion reintervention between male and female patients (P = 0.14 and P = 0.32, respectively). CONCLUSIONS: Female patients had lower incidence of cardiovascular risk factors but presented with higher Trans-Atlantic Inter-Society Consensus II classification and had higher rates of 30-day thrombotic acute limb ischemia. Male patients were more likely to require amputation within 30 days. Despite no differences in the mid-term, these short-term findings suggest that patient sex may be a relevant consideration in postoperative management and surveillance after endovascular treatment of AIOD.

Safety and mortality outcomes for direct oral anticoagulants in renal transplant recipients.

PURPOSE: Direct oral anticoagulants (DOACs) are increasingly used in renal transplant recipients (RTR), but relatively understudied in this population. We assess the safety of post-transplant anticoagulation with DOACs compared to warfarin. METHODS: We conducted a retrospective study of RTRs at the Mayo Clinic sites (2011-present) that were anticoagulated for greater than 3 months excluding the 1st month post-transplant. The main safety outcomes were bleeding and all-cause mortality. Concomitant antiplatelet and interacting drugs were noted. DOAC dose adjustment was assessed according to common US prescribing practices, guidelines, and/or FDA labeling. RESULTS: The median follow-up was longer for RTRs on warfarin (1098 days [IQR 521, 1517]) than DOACs (449 days [IQR 338, 942]). Largely, there were no differences in baseline characteristics and comorbidities between RTRs on DOACs (n = 208; apixaban 91.3%, rivaroxaban 8.7%) versus warfarin (n = 320). There was no difference in post-transplant use of antiplatelets, immunosuppressants, most antifungals assessed, or amiodarone. There was no significant difference in incident major bleeding (8.4 vs. 5.3%, p = 0.89), GI bleeding (4.4% vs. 1.9%, p = 0.98), or intra-cranial hemorrhage (1.9% vs. 1.4%, p = 0.85) between warfarin and DOAC. There was no significant difference in mortality in the warfarin group compared to DOACs when adjusted for follow-up time (22.2% vs. 10.1%, p = 0.21). Rates of post-transplant venous thromboembolism, atrial fibrillation or stroke were similar between the two groups. 32% (n = 67) of patients on DOACs were dose reduced, where 51% of those reductions were warranted. 7% of patients that were not dose reduced should have been. CONCLUSIONS: DOACs did not have inferior bleeding or mortality outcomes compared to warfarin in RTRs. There was greater use of warfarin compared to DOACs and a high rate of improper DOAC dose reduction.

Infections and antimicrobial prescribing in patients hospitalized with coronavirus disease 2019 (COVID-19) during the first pandemic wave.

Objective: To evaluate the rate of coinfections and secondary infections seen in hospitalized patients with COVID-19 and antimicrobial prescribing patterns. Methods: This single-center, retrospective study included all patients aged ≥18 years admitted with COVID-19 for at least 24 hours to a 280-bed, academic, tertiary-care hospital between March 1, 2020, and August 31, 2020. Coinfections, secondary infections, and antimicrobials prescribed for these patients were collected. Results: In total, 331 patients with a confirmed diagnosis of COVID-19 were evaluated. No additional cases were identified in 281 (84.9%) patients, whereas 50 (15.1%) had at least 1 infection. In total, of 50 patients (15.1%) who were diagnosed with coinfection or secondary infection had bacteremia, pneumonia, and/or urinary tract infections. Patients who had positive cultures, who were admitted to the ICU, who required supplemental oxygen, or who were transferred from another hospital for higher level of care were more likely to have infections. The most commonly used antimicrobials were azithromycin (75.2%) and ceftriaxone (64.9%). Antimicrobials were prescribed appropriately for 55% of patients. Conclusions: Coinfection and secondary infections are common in patients who are critically ill with COVID-19 at hospital admission. Clinicians should consider starting antimicrobial therapy in critically ill patients while limiting antimicrobial use in patients who are not critically ill.

Long-term follow-up on dusting versus basketing during ureteroscopy: a prospective multicenter trial from the EDGE Research Consortium.

In 2018, the Endourology Disease Group for Excellence (EDGE) published a prospective trial comparing dusting versus basketing during ureteroscopy. One hundred fifty-nine patients were included in the original analysis, which found no difference in stone-free rate at 3 months. We report the intermediate and long-term outcomes of patients included in the original trial. Two analyses were performed. At 1-year, a retrospective chart review was performed, and data collected on stone episodes, Emergency Department (ED) visits, hospital admissions and surgical interventions. To obtain long-term outcomes, the four sites with the largest initial accrual were included in a second phase of data collection with updated analyses. The patients from those sites were contacted, re-consented, and data were collected on stone surgical interventions, stone episodes, stone recurrences on imaging, emergency department (ED) visits, and hospital admissions for stone-related care since their original procedure. One-year follow-up data were collected in 111 of the original 159 (69.8%) patients from the nine sites. There were no statistically significant differences in the number of painful episodes, ED visits, hospital admissions, or surgical interventions. 94 patients from four sites were included in the long-term analysis. There were no statistically significant differences in surgical interventions, painful stone episodes, stone recurrence on imaging, ED visits or hospitalizations for stone-related events between the two groups. Long-term outcomes of dusting versus basketing during ureteroscopy indicate that there are no significant differences in clinical outcomes between the two surgical modalities.

Effect of Cannabidiol Oil on Post-ureteroscopy Pain for Urinary Calculi: A Randomized, Double-blind, Placebo-controlled Trial.

PURPOSE: Post-ureteroscopy stent placement carries significant morbidity which can interfere with daily life. This discomfort unfortunately leads to high utilization of opioid pain medications, which have a known risk of addiction. Cannabidiol oil represents an alternative analgesic that has proven anti-inflammatory and antinociceptive effects. The purpose was to evaluate the effect of a Food and Drug Administration-approved cannabidiol oil (Epidiolex) on pain control and opioid usage in the post-ureteroscopy setting. MATERIALS AND METHODS: This was a prospective, randomized, double-blind, placebo-controlled trial at a tertiary care center. Ninety patients undergoing ureteroscopy with stent placement for urinary stone disease were randomized 1:1 to placebo or 20 mg cannabidiol oil daily for 3 days postoperatively. Both groups were prescribed a rescue narcotic, tamsulosin, oxybutynin, and phenazopyridine. Daily pain scores, medication usage, and ureteral stent symptoms using the validated Ureteral Stent Symptom Questionnaire were recorded postoperatively. RESULTS: Both the placebo and cannabidiol oil groups were not different in pre- and perioperative characteristics. There was no difference in pain scores or opioid usage between groups postoperatively. The level of discomfort with ureteral stents was also not different between groups when comparing physical activity, sleep, urination, and activities of daily life. CONCLUSIONS: This randomized, blinded, placebo-controlled trial showed that cannabidiol oil is safe but ineffective when compared to placebo in reducing post-ureteroscopic stent discomfort or opioid usage. Despite the availability of numerous analgesic agents, stent symptoms continue to be a dissatisfier for most patients, suggesting additional work needs to focus on novel interventions and pain control.

The Fate of the Inconclusive Periprosthetic Joint Infection Workup and Reliability of Data Points.

In 2018, periprosthetic joint infection (PJI) criteria were revised to include a new category labeled "inconclusive." The purpose of this study was to characterize and describe the fate of the inconclusive PJI workup and to analyze preoperative factors associated with outcomes. We reviewed all PJI workups at our institution during a 3-year period (426 patients). Patients were labeled "infected," "not infected," or "inconclusive" according to 2018 PJI preoperative criteria. In addition to standard diagnostic variables, the presence or absence of clinical elements that increase the pretest probability of infection were collected. Patients with any missing preoperative diagnostic test results and those with clinical follow-up less than 30 days were excluded. Logistic regression was used to identify the factors associated with infection. Two hundred ninety-six workups remained after exclusion criteria were applied, consisting of 66 (22.2%) with a preoperative score of 6 or greater defined as infected, 52 (17.6%) inconclusive (score 2-5), and 178 (60.1%) not infected (score 0-1). Postoperative re-scoring of the inconclusive group based on intraoperative findings as per the 2018 criteria identified 6 of 52 (11.5%) as infected, 12 (23.1%) inconclusive, and 34 (65.4%) not infected. Among those preoperatively scored as inconclusive, variables statistically correlated with the presence of infection included history of PJI, factors that increase skin barrier penetration (eg, psoriasis and venous stasis), and presence of comorbidities predisposing to infection. For patients labeled inconclusive, clinical elements of the pretest probability for infection (eg, history of prior PJI) were as reliable as any diagnostic test, including alpha-defensin, in the diagnosis of PJI.

Gender differences in academic productivity, educational positions, and leadership appointments of physicians in the U.S.

BACKGROUND: Promotions in academic medicine are frequently based on number of publications and leadership positions held. While prior study has established women publish less than men, many evaluations are limited to individual specialties and do not evaluate involvement with educational activities. OBJECTIVE: To compare gender differences in academic output, intramural leadership positions, and educational leadership positions of academic physicians. METHODS: The curriculum vitae and de-identified demographic data of all permanent physicians employed at a multi-site academic medical center were reviewed from April to May 2020. Multivariable logistic and Poisson regressions evaluated leadership positions and number of publications. RESULTS: Of 3,359 physicians in the demographic database, 32.3% (n = 1,087) were women and 72.5% were white (n = 2,510). Of the 3,015 physicians in the curriculum vitae database, 32% (n = 962) were women. Women were more likely (p < 0.001) to be assistant professor (54% vs. 42.7%) and less likely to be associate (18.1% vs. 20.3%) or full professor (14.6% vs. 29.1%). Women assistant professors published 22% fewer articles (ratio estimate = 0.78, p < 0.001), associate professors 18% less (coefficient = 0.82, p < 0.001), and full professors 23% less (coefficient = 0.77, p < 0.001). Fewer women were program directors for residencies (1.6% vs. 2.9%, p = 0.02) or fellowships (5.4% vs. 7.4%, p = 0.04), and held fewer division or department leadership positions (OR 0.8, 95% CI as [0.6, 1.0], p = 0.03). CONCLUSION: Women physicians do not outperform men across any education, leadership, or publication category. A cultural shift is needed to redefine traditional metrics for leadership appointments if academic medicine hopes to achieve equity.

Cardiologist Evaluation and Approval Was the Primary Predictor of Kidney Transplant Candidacy and Transplantation Among Patients With Reduced Left Ventricular Ejection Fraction.

End-stage kidney disease patients with concomitant heart failure (HF) with reduced ejection fraction are often denied kidney transplantation. The aims of this study were to explore factors predictive of suitability for kidney transplant and to assess cardiovascular outcomes in patients with impaired left ventricular ejection fraction (LVEF) after transplant. Methods: We evaluated 109 consecutive adults with LVEF ≤40% at the time of initial kidney transplant evaluation between 2013 and 2018. Posttransplant cardiovascular outcomes were defined as nonfatal myocardial infarction (MI), admission for HF, cardiovascular death, and all-cause mortality. Results: A cardiologist participated in kidney transplant evaluation for 87% of patients and was present at 49% of transplant selection conferences. Twenty-four patients (22%) were denied by a cardiologist for kidney transplant' and 59 (54%) were denied by the selection committee, of whom 43 were because of cardiovascular risk. Forty-two (38%) patients were approved for kidney transplant. On univariate analysis, the variables associated with denial for kidney transplant included cardiologist denial, higher cardiac troponin T, prior coronary intervention, cardiovascular event, positive stress study, lower ejection fraction, and lower VO2 max (all P < 0.05). Cardiologist denial was the most significant predictor of denial for kidney transplant in different multivariate models. At a median follow-up of 15 mo, 5 (5%) suffered nonfatal MI, 13 (12%) were hospitalized for HF exacerbation, and 17 (16%) died. Only 22 patients, 52% of those approved, underwent kidney transplant. After kidney transplant, there was 1 death, 1 nonfatal MI, and 3 hospitalizations for HF. Median LVEF improved from 38% before listing to 55% posttransplant. Conclusions: Cardiologist denial was the primary predictor of rejection for kidney transplant. Despite careful selection, prevalence of cardiovascular events and mortality after kidney transplant was 23%. There is need for a structured multidisciplinary approach for patients with impaired LVEF.

Safety attitudes culture remain stable in a transplant center: evidence from the coronavirus pandemic.

Background: We sought to understand how safety culture may evolve during disruption, by using the COVID-19 pandemic as an example, to identify vulnerabilities in the system that could impact patient outcomes. Methods: A cross-sectional analysis of transplant personnel at a high-volume transplant center was conducted using the Safety Attitudes Questionnaire (SAQ). Survey responses were scaled and evaluated pre- and post-COVID-19 (2019 and 2021). Results: Two-hundred and thirty-eight responses were collected (134 pre-pandemic and 104 post-pandemic). Represented organ groups included: kidney (N = 89;38%), heart (N = 18;8%), liver (N = 54;23%), multiple (N = 66;28%), and other (N = 10;4%). Responders primarily included nurses (N = 75;34%), administration (N = 50;23%), and physicians (N = 24;11%). Workers had high safety, job satisfaction, stress recognition, and working conditions satisfaction (score >75) both before and after the pandemic with overlapping responses across both timepoints. Stress recognition, safety, and working conditions improved post-COVID-19, but teamwork, job satisfaction, and perceptions of management were somewhat negatively impacted (all p > 0.05). Conclusions: Despite the serious health care disruptions induced by the pandemic, high domain ratings were notable and largely maintained in a high-volume transplant center. The SAQ is a valuable tool for healthcare units and can be used in longitudinal assessments of transplant culture of safety as a component of quality assurance and performance improvement initiatives.

Shared decision-making in opioid prescribing for minimally invasive hysterectomy: A prospective randomized controlled trial.

OBJECTIVE: To determine the impact of shared decision-making in postsurgical opioid prescribing in women who underwent minimally invasive (MIS) hysterectomy. DESIGN: A randomized controlled trial. SETTING: A single, tertiary care, academic center. PATIENTS AND PARTICIPANTS: From January 2019 through April 2020, 73 women aged 18 years and older who had a planned MIS hysterectomy with the Department of Gynecology were enrolled into the study (36 in the standard arm and 37 in the patient-directed arm). INTERVENTIONS: Participants were assigned either to the standard arm (30 tablets) or patient-directed arm (0-30 tablets) of oxycodone 5 mg. MAIN OUTCOME MEASURES: The primary outcome was the percentage of excess opioid tablets, calculated by the number of unused tablets divided by the number of tablets prescribed. Secondary outcomes included total opioid tablets used, frequency of obtaining additional opioid tablets after discharge, frequency of unscheduled post-operative visits, and patient satisfaction with number of opioid tablets prescribed. RESULTS: Age, race, and body mass index did not differ between groups. Hysterectomies were performed via laparoscopy (16.9 percent), robotic-assisted laparoscopy (38.5 percent), and vaginal routes (44.6 percent). The median (IQR) number of oxycodone prescribed in the patient-directed arm was 15.0 (12.0 and 24.0) tablets. The standard arm had a greater percentage of excess oxycodone tablets 73.6 percent (0.03) than the patient-directed arm 56.3 percent (0.03, p < .01). However, there was no difference in the total number of oxycodone used by patients in the standard (mean 7.9 [0.5] tablets) and patient-directed arms (mean 8.4 [0.5] tablets, p = .50). The mean number of oxycodone used for the entire cohort was 8.1 (0.4) tablets. CONCLUSIONS: Shared decision-making significantly decreased the percent of excess oxycodone tablets but did not decrease the total number of oxycodone tablets used in patients undergoing MIS hysterectomy. Patients used about 22 tablets less than the standard 30 tablets prescribed.

Impact of Glomerulitis on Long-term Outcomes After Kidney Transplantation.

The Banff classification scheme provides a framework for interpreting transplant kidney biopsies and has undergone various updates in the past 2 decades especially related to antibody-mediated rejection. The clinical significance of early glomerulitis seen within 4 mo on protocol biopsies has received limited attention. We hypothesized that early glomerulitis seen on protocol biopsies will lead to significant adverse outcomes as assessed by histopathology and allograft outcome. Methods: A single-center retrospective study of a cohort of patients who underwent protocol biopsies within 4 mo after transplantation with timely follow-up protocol biopsies were assessed. Patients with recurrent glomerulonephritis were excluded. Results: We calculated glomerulitis (g) scores for 2212 biopsy specimens and identified 186 patients with glomerulitis (g > 0) and 2026 patients without glomerulitis (g = 0). The progression to chronic transplant glomerulopathy at 1 and 2 y was higher in patients with g > 0 as compared with g = 0 (year 1, 10.7% versus 2.3% [P < 0.001]' respectively; year 2, 17.2% versus 4.3% [P < 0.001], respectively) with no difference in other chronic lesions. The death-censored graft failure rate was higher in patients with g > 0 as compared with g = 0 (hazard ratio, 1.68 [95% CI, 1.07-2.65]; P = 0.02). We did not find any difference in outcomes in glomerulitis group based on donor-specific antibody. Conclusion: Our findings suggest that early glomerulitis (seen within 4 mo after transplantation) may lead to clinically significant long-term changes and thus could be a target for early intervention therapies.

Adoption of High-sensitivity Troponin Testing and Emergency Physician Ordering Behavior.

INTRODUCTION: Emergency departments (ED) are rapidly replacing conventional troponin assays with high-sensitivity troponin tests. We sought to evaluate emergency physician utilization of troponin tests before and after high-sensitivity troponin introduction in our ED. METHODS: We retrospectively examined 9,477 ED encounters, identifying the percentage in which physicians ordered a serum troponin both before and after our institution adopted a high-sensitivity troponin test. RESULTS: After introduction of high-sensitivity troponin testing, the percentage of ED encounters in which physicians ordered troponin studies decreased (28.3% before vs 22% after; P <.001), with the drop most pronounced in admitted patients (decrease of 10.9% [95% confidence interval [CI]: 7.3%-14.5%] in admitted patients vs decrease of 3.6% [95% CI: 1.7%-5.4%] in discharged patients; P<.001) CONCLUSION: Introduction of high-sensitivity troponin testing was associated with a decrease in troponin ordering. While the reasons for this are unclear, it is possible that physicians became more selective in their ordering behavior because of the lower specificity of high-sensitivity troponin.

Migraine with aura associates with a higher artificial intelligence: ECG atrial fibrillation prediction model output compared to migraine without aura in both women and men.

OBJECTIVE: To compare the artificial intelligence-enabled electrocardiogram (AI-ECG) atrial fibrillation (AF) prediction model output in patients with migraine with aura (MwA) and migraine without aura (MwoA). BACKGROUND: MwA is associated with an approximately twofold risk of ischemic stroke. Longitudinal cohort studies showed that patients with MwA have a higher incidence of developing AF compared to those with MwoA. The Mayo Clinic Cardiology team developed an AI-ECG algorithm that calculates the probability of concurrent paroxysmal or impending AF in ECGs with normal sinus rhythm (NSR). METHODS: Adult patients with an MwA or MwoA diagnosis and at least one NSR ECG within the past 20 years at Mayo Clinic were identified. Patients with an ECG-confirmed diagnosis of AF were excluded. For each patient, the ECG with the highest AF prediction model output was used as the index ECG. Comparisons between MwA and MwoA were conducted in the overall group (including men and women of all ages), women only, and men only in each age range (18 to <35, 35 to <55, 55 to <75, ≥75 years), and adjusted for age, sex, and six common vascular comorbidities that increase risk for AF. RESULTS: The final analysis of our cross-sectional study included 40,002 patients (17,840 with MwA, 22,162 with MwoA). The mean (SD) age at the index ECG was 48.2 (16.0) years for MwA and 45.9 (15.0) years for MwoA (p < 0.001). The AF prediction model output was significantly higher in the MwA group compared to MwoA (mean [SD] 7.3% [15.0%] vs. 5.6% [12.4%], mean difference [95% CI] 1.7% [1.5%, 2.0%], p < 0.001). After adjusting for vascular comorbidities, the difference between MwA and MwoA remained significant in the overall group (least square means of difference [95% CI] 0.7% [0.4%, 0.9%], p < 0.001), 18 to <35 (0.4% [0.1%, 0.7%], p = 0.022), and 35 to <55 (0.5% [0.2%, 0.8%], p < 0.001), women of all ages (0.6% [0.3%, 0.8%], p < 0.001), men of all ages (1.0% [0.4%, 1.6%], p = 0.002), women 35 to <55 (0.6% [0.3%, 0.9%], p < 0.001), and men 18 to <35 (1.2% [0.3%, 2.1%], p = 0.008). CONCLUSIONS: Utilizing a novel AI-ECG algorithm on a large group of patients, we demonstrated that patients with MwA have a significantly higher AF prediction model output, implying a higher probability of concurrent paroxysmal or impending AF, compared to MwoA in both women and men. Our results suggest that MwA is an independent risk factor for AF, especially in patients <55 years old, and that AF-mediated cardioembolism may play a role in the migraine-stroke association for some patients.
