From the Operating Room to Online: Medical Student Surgery Education in the Time of COVID-19.

BACKGROUND: On March 17, 2020 the Association of American Medical Colleges recommended dismissal of medical students from clinical settings due to the COVID-19 pandemic. Third-year (M3) and fourth-year (M4) medical students were at home, M4s were interested in teaching, and residents and faculty had fewer clinical responsibilities due to elective surgery cancellations. To continue M3 access to education, we created a virtual surgery elective (VSE) that aimed to broaden students' exposure to, and elicit interest in, general surgery (GS). METHODS: Faculty, surgical residents, and M4s collaborated to create a 2-wk VSE focusing on self-directed learning and direct interactions with surgery faculty. Each day was dedicated to a specific pathology commonly encountered in GS. A variety of teaching methods were employed including self-directed readings and videos, M4 peer lectures, case-based learning and operative video review with surgery faculty, and weekly surgical conferences. A VSE skills lab was also conducted to teach basic suturing and knot-tying. All lectures and skills labs were via Zoom videoconference (Zoom Video Communications Inc). A post-course anonymous survey sent to all participants assessed changes in their understanding of GS and their interest in GS and surgery overall. RESULTS: Fourteen M3s participated in this elective over two consecutive iterations. The survey response rate was 79%. Ninety-one percent of students believed the course met its learning objectives "well" or "very well." Prior to the course, 27% reported a "good understanding" and 0% a "very good" understanding of GS. Post-course, 100% reported a "good" or "very good" understanding of GS, a statistically significant increase (P = 0.0003). Eighty-two percent reported increased interest in GS and 64% reported an increase in pursuing GS as a career. CONCLUSIONS: As proof of concept, this online course successfully demonstrated virtual medical student education can increase student understanding of GS topics, increase interest in GS, and increase interest in careers in surgery. To broaden student exposure to GS, we plan to integrate archived portions of this course into the regular third-year surgery clerkship and these can also be used to introduce GS in the preclinical years.

S157-a structured early intervention program in patients with predicted poor long-term outcome following bariatric surgery: a prospective randomized study.

BACKGROUND: Early postoperative weight loss can be predictive of one-year outcomes. It is unclear if poor performers identified in the first post-operative month can have improvement in outcomes with additional support and education. PURPOSE: To evaluate the impact of a structured targeted support program for patients with lower-than-average early post-operative weight loss on 1-year outcomes. METHODS: This was a prospective randomized study of bariatric surgery patients who experienced less than 50th percentile excess body weight loss (%EWL) at 3 weeks. Subjects with EWL < 18% were randomized into two groups: an intervention (IV) arm or a control (NI, no intervention) arm. The IV arm was offered a program with 7-weekly behavioral support sessions, while the NI patients received routine post-operative care. RESULTS: A total of 128 patients were randomized: 65 NI and 63 IV. In the IV group, 20 attended all sessions, 7 attended < 4, and 36 did not participate. There was no difference in baseline demographics, procedure type, or BMI. At 1 year, there was no difference in %EWL (ratio 0.993, 95% CI 0.873, 1.131), %EBMIL (ratio 0.997, 95% CI 0.875, 1.137), and %TWL (ratio 1.016, 95% CI 0.901, 1.146) between groups. A subgroup analysis including only the subjects who participated in all seven sessions showed similar results. CONCLUSION: Patients who present with suboptimal weight loss early after bariatric surgery do not experience a significant weight loss improvement with a structured behavioral support program. Importantly, despite being alerted to their poor early weight loss, patients demonstrated poor adherence to the proposed interventions.

SAGES primer for taking care of yourself during and after the COVID-19 crisis.

COVID-19 is a pandemic which has affected almost every aspect of our life since starting globally in November 2019. Given the rapidity of spread and inadequate time to prepare for record numbers of sick patients, our surgical community faces an unforeseen challenge. SAGES is committed to the protection and care of patients, their surgeons and staff, and all who are served by the medical community at large. This includes physical health, mental health, and well-being of all involved. The fear of the unknown ahead can be paralyzing. International news media have chronicled the unthinkable situations that physicians and other health care providers have been thrust into as a result of the COVID-19 pandemic. These situations include making life or death decisions for patients and their families regarding use of limited health care resources. It includes caring for patients with quickly deteriorating conditions and limited treatments available. Until recently, these situations seemed far from home, and now they are in our own hospitals. As the pandemic broadened its reach, the reality that we as surgeons may be joining the front line is real. It may be happening to you now; it may be on the horizon in the coming weeks. In this context, SAGES put together this document addressing concerns on clinician stressors in these times of uncertainty. We chose to focus on the emotional toll of the situation on the clinician, protecting vulnerable persons, reckoning with social isolation, and promoting wellness during this crisis. At the same time, the last part of this document deals with the "light at the end of the tunnel," discussing potential opportunities, lessons learned, and the positives that can come out of this crisis.

Women undergoing aortic surgery are at higher risk for unplanned readmissions compared with men especially when discharged home.

OBJECTIVE: Women undergoing vascular surgery have higher morbidity and mortality. Our study explores gender-based differences in patient-centered outcomes such as readmission, length of stay (LOS), and discharge destination (home vs nonhome facility) in aortic aneurysm surgery. METHODS: Patients were identified from the American College of Surgeons National Surgical Quality Improvement Project database (2011-2013) undergoing abdominal, thoracic, and thoracoabdominal aortic aneurysms (N = 17,763), who were discharged and survived their index hospitalization. The primary outcome was unplanned readmission, and secondary outcomes were discharge to a nonhome facility, LOS, and reasons for unplanned readmission. Univariate, multivariate, and stratified analyses based on gender and discharge destination were used. RESULTS: Overall, 1541 patients (8.7%) experienced an unplanned readmission, with a significantly higher risk in women vs men (10.8% vs 8%; P < .001) overall (Procedure subtypes: abdominal aortic aneurysm [10.1% vs 7.7%; P < .001], thoracic aortic aneurysm [14.1% vs 13.5%; P = .8], and thoracoabdominal aortic aneurysm [14.8% vs 10%; P = .051]). The higher odds of readmission in women compared with men persisted in multivariate analysis after controlling for covariates (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.05-1.4). Similarly, the rate of discharge to a nonhome facility was nearly double in women compared with men (20.6% vs 10.7%; P < .001), but discharge to a nonhome facility was not a significant predictor of unplanned readmission. Upon stratification by discharge destination, the higher odds of readmissions in women compared with men occurred in patients who were discharged home (OR, 1.2; 95% CI, 1.02-1.4) but not in those who were discharged to a nonhome facility (OR, 1.06; 95% CI, 0.8-1.4). Significant differences in LOS were seen in patients who were discharged home. No gender differences were found in reasons for readmission with the three most common reasons being thromboembolic events, wound infections, and pneumonia. CONCLUSIONS: Gender disparity exists in the risk of unplanned readmission among aortic aneurysm surgery patients. Women who were discharged home have a higher likelihood of unplanned readmission despite longer LOS than men. These data suggest that further study into the discharge planning processes, social factors, and use of rehabilitation services is needed for women undergoing aortic procedures to decrease readmissions.

Obstructive sleep apnea and incidence of postoperative delirium after elective knee replacement in the nondemented elderly.

BACKGROUND: Postoperative delirium, a common complication in the elderly, can occur following any type of surgery and is associated with increased morbidity and mortality; it may also be associated with subsequent cognitive problems. Effective therapy for postoperative delirium remains elusive because the causative factors of delirium are likely multiple and varied. METHODS: Patients 65 yr or older undergoing elective knee arthroplasty were prospectively evaluated for postoperative Diagnostic and Statistical Manual of Mental Disorders-IV delirium. Exclusion criteria included dementia, mini-mental state exam score less than 24, delirium, clinically significant central nervous system/neurologic disorder, current alcoholism, or any serious psychiatric disorder. Delirium was assessed on postoperative days 2 and 3 using standardized scales. Patients' preexisting medical conditions were obtained from medical charts. The occurrence of obstructive sleep apnea was confirmed by contacting patients to check their polysomnography records. Data were analyzed using Pearson chi-square or Wilcoxon rank sum tests and multiple logistic regressions adjusted for effects of covariates. RESULTS: Of 106 enrolled patients, 27 (25%) developed postoperative delirium. Of the 15 patients with obstructive sleep apnea, eight (53%) experienced postoperative delirium, compared with 19 (20%) of the patients without obstructive sleep apnea (P = 0.0123, odds ratio: 4.3). Obstructive sleep apnea was the only statistically significant predictor of postoperative delirium in multivariate analyses. CONCLUSIONS: This is the first prospective study employing validated measures of delirium to identify an association between preexisting obstructive sleep apnea and postoperative delirium.

Association between Serum IGF-I levels and Postoperative Delirium in Elderly Subjects Undergoing Elective Knee Arthroplasty.

Evidence is mixed for an association between serum insulin-like growth factor-I (IGF-I) levels and postoperative delirium (POD). The current study assessed preoperative serum IGF-I levels as a predictor of incident delirium in non-demented elderly elective knee arthroplasty patients. Preoperative serum levels of total IGF-I were measured using a commercially available Human IGF-I ELISA kit. POD incidence and severity were determined using DSM-IV criteria and the Delirium Rating Scale-Revised-98 (DRS-R98), respectively. Median IGF-I levels in delirious (62.6 ng/ml) and non-delirious groups (65.9 ng/ml) were not significantly different (p = 0.141). The ratio (95% CI) of geometric means, D/ND, was 0.86 (0.70, 1.06). The Hodges-Lehmann median difference estimate was 7.23 ng/mL with 95% confidence interval (-2.32, 19.9). In multivariate logistic regression analysis IGF-I level was not a significant predictor of incident POD after correcting for medical comorbidities. IGF-I levels did not correlate with DRS-R98 scores for delirium severity. In conclusion, we report no evidence of association between serum IGF-I levels and incidence of POD, although the sample size was inadequate for a conclusive study. Further efforts to investigate IGF-I as a delirium risk factor in elderly should address comorbidities and confounders that influence IGF-I levels.
