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.

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.

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 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.

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.

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.

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.

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.

The role of race and ethnicity in the dermatology applicant match process.

OBJECTIVE: The field of dermatology is one of the least racially diverse specialties. We aimed to identify ways in which minorities become underrepresented within dermatology. METHODS: We surveyed dermatology applicants who applied to Mayo Clinic in Scottsdale, AZ during the 2018-2019 application cycle and Mayo Clinic in Rochester, Scottsdale, and Jacksonville during the 2019-2020 application cycles. Underrepresented minorities (URM) were defined as Latino/Latina, African American, American Indian/Alaska Native, or Native Hawaiian/Pacific Islander. RESULTS: In total, 149 and 142 dermatology applicants completed the initial 2019 and 2020 surveys, 112 and 124 completed the follow-up surveys. The racial breakdown was 69.9% Caucasian, 23.7% Asian, 5.4% African American, 0.4% American Indian/Alaska Native, and 0.7% Native Hawaiian/Pacific Islander. Eight percent identified as Hispanic/Latino. Median Step 1 scores were lower for URM (p<0.01). URM had more publications (p=0.01). There were no observed differences in away rotations or interviews attended. URM were less likely to match (76.7%) vs. Whites (88.4%) and Asians (96.0%; p=0.03). CONCLUSION: URM are taking out more loans, pursuing research fellowships more often than their White counterparts, publishing more, completing the same number of away rotations and interviews, yet have lower match rates leading to underrepresentation in the field. It is important to realize how Step scores might reflect and reproduce disparities between different racial/ethnic backgrounds, in turn influencing the racial composition of dermatology residency programs.

The role research gap years play in a successful dermatology match.

BACKGROUND: A new trend includes taking a dedicated year away from medical school to complete a research fellowship. There is minimal data on the benefit of a gap year. We aimed to identify if a gap year makes a dermatology applicant more successful in The Match. METHODS: Dermatology applicants who applied to Mayo Clinic Arizona for the 2018-2019 application cycle and Mayo Clinic Rochester, Arizona, and Florida for the 2019-2020 application cycle were surveyed. RESULTS: In total, 291 dermatology applicants completed the initial survey, and 236 completed the follow-up survey. Ninety applicants took a gap year, 198 applicants did not. There was no significant difference in match rates. When comparing match rates at top dermatology residency programs, 40.6% of gap-year applicants matched to these residencies versus 19.0% of no gap-year applicants (P < 0.01). CONCLUSION: Applicants should weigh the opportunity costs before pursuing research gap years as they may not be universally helpful. Applicants who want to match at a top dermatology program may benefit from a research gap year. This data may have limited generalizability outside of the United States.

Cavitary Coccidioidomycosis: Impact of azole antifungal therapy.

Approximately 5 to 15% of patients with pulmonary coccidioidomycosis subsequently develop pulmonary cavities. These cavities may resolve spontaneously over a number of years; however, some cavities never close, and a small proportion causes complications such as hemorrhage, pneumothorax or empyema. The impact of azole antifungal treatment on coccidioidal cavities has not been studied. Because azoles are a common treatment for symptomatic pulmonary coccidioidomycosis, we aimed to assess the impact of azole therapy on cavity closure. From January 1, 2004, through December 31, 2014, we retrospectively identified 313 patients with cavitary coccidioidomycosis and excluded 42 who had the cavity removed surgically, leaving 271 data sets available for study. Of the 271 patients, 221 (81.5%) received azole therapy during 5-year follow-up; 50 patients did not receive antifungal treatment. Among the 271 patients, cavities closed in 38 (14.0%). Statistical modeling showed that cavities were more likely to close in patients in the treated group than in the nontreated group (hazard ratio, 2.14 [95% CI: 1.45-5.66]). Cavities were less likely to close in active smokers than nonsmokers (11/41 [26.8%] vs 97/182 [53.3%]; P = 0.002) or in persons with than without diabetes (27/74 [36.5%] vs 81/149 [54.4%]; P = 0.01).We did not find an association between cavity size and closure. Our findings provide rationale for further study of treatment protocols in this subset of patients with coccidioidomycosis. LAY SUMMARY: Coccidioidomycosis, known as valley fever, is a fungal infection that infrequently causes cavities to form in the lungs, which potentially results in long-term lung symptoms. We learned that cavities closed more often in persons who received antifungal drugs, but most cavities never closed completely.

Effect of bowel preparation volume in inpatient colonoscopy. Results of a prospective, randomized, comparative pilot study.

BACKGROUND: Inpatient status has been shown to be a predictor of poor bowel preparation for colonoscopy; however, the optimal bowel preparation regimen for hospitalized patients is unknown. Our aim was to compare the efficacy of bowel preparation volume size in hospitalized patients undergoing inpatient colonoscopy. METHODS: This prospective, single blinded (endoscopist), randomized controlled trial was conducted as a pilot study at a tertiary referral medical center. Hospitalized patients undergoing inpatient colonoscopy were assigned randomly to receive a high, medium, or low-volume preparation. Data collection included colon preparation quality, based on the Boston Bowel Preparation Scale, and a questionnaire given to all subjects evaluating the ability to completely finish bowel preparation and adverse effects (unpleasant taste, nausea, and vomiting). RESULTS: Twenty-five colonoscopies were performed in 25 subjects. Patients who received low-volume preparation averaged a higher mean total BBPS (7.4, SD 1.62), in comparison to patients who received high-volume (7.0, SD 1.41) and medium-volume prep (6.9, SD 1.55), P = 0.77. When evaluating taste a higher score meant worse taste. The low-volume group scored unpleasant taste as 0.6 (0.74), while the high-volume group gave unpleasant taste a score of 2.2 (0.97) and the medium-volume group gave a score of 2.1 (1.36), P < 0.01. CONCLUSION: In this pilot study we found that low-volume colon preparation may be preferred in the inpatient setting due its better rate of tolerability and comparable bowel cleanliness when compared to larger volume preparation, although we cannot overreach any definitive conclusion. Further more robust studies are required to confirm these findings. TRIAL REGISTRATION: The Affect of Low-Volume Bowel Preparation for Hospitalized Patients Colonoscopies. TRIAL REGISTRATION: NCT01978509 (terminated). Retrospectively registered on November 07, 2013.

Clinical Outcomes of Portosystemic Shunts on the Outcome of Liver Transplantation.

Spontaneous portosystemic shunts (SPSSs) have been associated with worse clinical outcomes in the pre-liver transplantation (LT) setting, but little is known about their post-LT impacts. Our aim was to compare LT candidates with and without SPSSs and assess the impact of SPSSs on patient mortality and graft survival in the post-LT setting. Patients 18 years or older with abdominal imaging done prior to LT were included. Exclusion criteria were the presence of pre-LT surgical shunts, LT indications other than cirrhosis, and combined solid organ transplantations. SPSSs were classified as absent, small, or large according to their maximum diameter (8 mm). Multiple variables that could influence the post-LT course were extracted for analysis. Patient and graft survival were estimated using the Kaplan-Meier method and were compared between groups using a log-rank test. The project received institutional review board approval. We extracted data from 326 patients. After comparing patients without SPSS or with small or large SPSSs, no statistical difference was found for overall patient survival: no SPSS (n = 8/63), reference; small SPSS (n = 18/150), hazard ratio (HR), 1.05 (95% confidence interval [CI], 0.45-2.46); and large SPSS (n = 6/113), HR, 0.60 (95% CI, 0.20-1.78); P = 0.20. Also, no difference was found for graft survival: no SPSS (n = 11/63), reference; small SPSS (n = 21/150), HR, 0.80 (95% CI, 0.38-1.70); large SPSS (n = 11/113), HR, 0.59 (95% CI, 0.25-1.40); P = 0.48. Similarly, no statistical significance was found for these variables when comparing if the graft used was procured from a donation after circulatory death donor versus a donation after brain death donor. In conclusion, the previously described association between SPSSs and worse clinical outcomes in pre-LT patients seems not to persist once patients undergo LT. This study suggests that no steps to correct SPSS intraoperatively are necessary.
