Protocol-based treatment of spontaneous hemorrhage from varicose veins prevents recurrence of bleeding.

BACKGROUND: Spontaneous hemorrhage from erosion of varicose veins through the skin is a serious and occasionally fatal complication of varicose vein disease. Various treatments, both acute and delayed, have been advocated. Our two-step clinical protocol was designed to prevent further hemorrhage without delay and to provide durable freedom from recurrent bleeding. METHODS: All patients referred to our surgical vein practice with hemorrhage from varicose veins were entered into a prospective registry. On presentation, all patients underwent diagnostic duplex ultrasound for venous reflux. Immediate treatment consisted of ultrasound-guided polidocanol/CO2 foam sclerotherapy of the bleeding varicosity and adjacent veins. Subsequent endovenous ablation of underlying incompetent axial veins, with concurrent microphlebectomy when indicated, was scheduled and performed within 8 weeks. RESULTS: Fifty-nine patients were referred with recent hemorrhage from varicose veins over a period of 4 years. Fifty-six (95%) had an ultrasound-identified tributary varicosity underlying the point of bleeding, and three had a skin-surface erosion only and no ultrasound-identified underlying tributary. Of the 59 study patients, 52 underwent prompt polidocanol/CO2 foam sclerotherapy, targeted to both the underlying tributary (when present) as well as the cutaneous bleeding varicosity. The remaining seven either declined sclerotherapy or were ineligible. Underlying incompetence of axial (great, small, or anterior saphenous) veins was found in 54 patients (92%). Of these patients with truncal vein incompetence, 48 underwent ablation-5 declined and 1 was too frail for any further intervention. There were no recurrent bleeds in the interval between immediate sclerotherapy and scheduled ablation. During a mean follow-up of 2.2 years, four patients (7%) had late, recurrent hemorrhage: one had failed to return for their scheduled ablation, two were on chronic anticoagulation, and one had severe right heart failure. All four were retreated without further recurrence. CONCLUSIONS: A two-step protocol of immediate ultrasound-guided foam sclerotherapy, followed within 8 weeks by endovenous ablation of incompetent axial veins and concurrent microphlebectomy, provided rapid and efficient treatment with durable freedom from subsequent hemorrhage.

Quantitative measurement of pitting edema with a novel edema ruler.

Lower extremity edema is a symptom of chronic venous disease and venous insufficiency. However, clinical evaluations rely on the qualitative evaluation of the pitting depth, which is neither well-defined nor quantitative. We created a novel three-dimensionally printed edema ruler as a quantitative method to measure pitting depth. Twenty-five patients (50 legs) with chronic venous disease were evaluated for ankle edema using the edema ruler. The results demonstrate excellent intraclass correlation for both single (0.944, P < .001) and average (0.971, P < .001) measurements. The edema ruler is a noninvasive, useful, and objective tool for the clinical measurement of lower extremity edema.

Small saphenous vein aneurysm diagnosis and treatment.

Venous aneurysms are rare, particularly those arising from the superficial venous system. Current limited evidence suggests that congenital weakness of the vein wall, degenerative changes, trauma and inflammation are among potential causes. Surgical management has been the mainstay treatment modality of venous aneurysms. Surgical approaches and techniques should be tailored on a case-by-case basis, taking into consideration aneurysm location, size, shape and presence of complications (ie, rupture or thrombosis). In this report, we present a male patient in his late thirties who presented with right leg swelling and achiness 2 years following right lower extremity blunt trauma and was found to have a 3 cm small saphenous vein aneurysm extending to the saphenopopliteal junction. The patient was successfully treated with excision of the aneurysm via a posterior approach. This case report adds to the current literature and may help to define future treatment recommendations.

Audience Response System (ARS) Use in the SCORE (Surgical Council on Resident Education) Surgery Training Curriculum: A Mixed Methodology Study.

Background Audience Response Systems (ARS) could help overcome the limitations of traditional lectures by providing interactivity, engagement, and assessment. The perception of ARS use in surgical education is not well documented. Objective Examine the use of an ARS in teaching This Week In SCORE (Surgical Council on Resident Education)sessions to general surgery residents and medical students. Methods  ARS was used at weekly SCORE question sessions in a new general surgery residency program by four residents, 97 medical students, and 20 faculty. The study employed a mixed quantitative and qualitative method: two separate 10-question surveys for faculty and trainees (49% response rate) and a focus group discussion that included one faculty member, two residents, and two students. Results In 85 (85%) responses, the faculty favored the use of ARS in SCORE. Among the total of 510 responses from 51 residents and students, 57% agreed with the favorable use of ARS, while 28% were neutral and, in 14% of cases, negative. A greater proportion of faculty and learners preferred ARS over traditional lectures. The focus group content analysis showed a positive effect and preference from learners and faculty. Engagement, thinking stimulation, and group participation were the most common positive comments. No significant negative influence on ARS use was reported. Conclusions The use of an ARS in This Week In SCORE â€‹â€‹â€‹sessions were preferred by most of the faculty and a majority of learners. The benefits are ease of use and stimulation of discussion. ARS has the potential for more widespread utilization in additional educational settings.

Is There a Role for Neoadjuvant Systemic Therapy for cT4bM0 Colon Cancer? A Propensity Score-Matched Analysis of the National Cancer Database.

BACKGROUND: Nonmetastatic T4b colon cancer has been traditionally treated with upfront surgery, often requiring technically challenging multiorgan resection. Neoadjuvant chemotherapy can potentially downsize these tumors and improve their resectability. OBJECTIVE: This study aimed to explore trends and outcomes of neoadjuvant chemotherapy use compared to upfront surgery in patients with nonmetastatic T4b colon cancer. This study also sought to determine factors associated with increased neoadjuvant chemotherapy use and with overall survival. DESIGN: Retrospective cohort study. SETTINGS: Conducted using the National Cancer Database. PATIENTS: Patients with nonmetastatic T4b colon cancer who underwent colectomy (2006-2016) were included in the study. Patients receiving neoadjuvant chemotherapy were propensity-matched (1:2) to those who underwent upfront surgery in either clinically node-negative or node-positive disease. MAIN OUTCOME MEASURES: Postoperative outcomes (length of stay, 30-d readmission, 30/90-d mortality), oncologic resection adequacy (R0 rate, number of resected/positive nodes), and overall survival were the main outcome measures. RESULTS: Neoadjuvant chemotherapy was used in 7.7% of the patients. Neoadjuvant chemotherapy use increased over the study period from 4% to 16% in the entire cohort, from 3% to 21% in patients with clinically node-positive disease, and from 6% to 12% in patients with clinically node-negative disease. Factors associated with increased use of neoadjuvant chemotherapy included younger age (OR 0.97; 95% CI, 0.96-0.98; p < 0.001), male sex (OR 1.35; 95% CI, 1.11-1.64; p = 0.002), recent diagnosis year (OR 1.16; 95% CI, 1.12-1.20; p < 0.001), academic centers (OR 2.65; 95% CI, 2.19-3.22; p < 0.001), clinically node-positive (OR 1.23; 95% CI, 1.01-1.49; p = 0.037), and tumor located in the sigmoid colon (OR 2.44; 95% CI, 1.97-3.02; p < 0.001). Patients who received neoadjuvant chemotherapy had significantly higher R0 resection compared with upfront surgery (87% vs 77%; p < 0.001). On multivariable analysis, neoadjuvant chemotherapy was associated with higher overall survival (HR 0.76; 95% CI, 0.64-0.91; p = 0.002). On propensity-matched analyses, neoadjuvant chemotherapy was associated with a higher 5-year overall survival compared to upfront surgery in patients with clinically node-positive disease (57% vs 43%; p = 0.003) but not in patients with clinically node-negative disease (61% vs 56%; p = 0.090). LIMITATIONS: Retrospective design. CONCLUSION: Neoadjuvant chemotherapy use for nonmetastatic T4b has increased significantly on the national level, more so in patients with clinically node-positive disease. Patients with node-positive disease treated with neoadjuvant chemotherapy had higher overall survival compared to those who underwent upfront surgery.

Identifying potentially avoidable femoral to popliteal expanded polytetrafluoroethylene bypass for claudication using cross-site blinded peer review.

OBJECTIVE: The surgical treatment of claudication can be associated with significant morbidity and costs. There are growing concerns that some patients proceed to interventions without first attempting evidence-based nonoperative management. We used a direct, cross-site, blinded expert review to evaluate the appropriateness of the surgical treatment of claudication. METHODS: We enlisted practicing vascular surgeons to perform retrospective clinical assessments of lower extremity bypass procedures in a statewide clinical registry. Cases were limited to elective, open, infrainguinal bypasses performed for claudication using prosthetic grafts. Reviewing surgeons were randomly assigned 10 cases from a sample of 139 anonymized bypass operations and instructed to evaluate procedural appropriateness based on their expert opinion and evidence-based guidelines for preoperative treatment, namely, antiplatelet, statin, cilostazol, exercise, and smoking cessation therapy as documented in the medical record. Ninety-day episode payments were estimated from a distinct but similar cohort of patients undergoing lower extremity bypass for claudication. RESULTS: Of 325 total reviews, surgeons stated they would not have recommended bypass in 134 reviews (41%) and deemed bypass inappropriate in 122 reviews (38%). The most common reason for inappropriateness was lack of preoperative medical and lifestyle therapy, which was present in 63% of reviews where bypass was deemed appropriate and 39% of reviews where bypass was deemed inappropriate (P < .001). Surgeons stated they would have recommended additional preoperative therapy in 65% of reviews where bypass was deemed inappropriate and 35% of reviews where bypass was deemed appropriate (P < .001). The mean total episode payments in a similar cohort of 1458 patients undergoing elective open lower extremity bypass for claudication were $31,301 ± $21,219. Extrapolating to the 325 reviews, the 134 reviews in which surgeons would not have recommended bypass were associated with potentially avoidable estimated total payments of $4,194,334, and the 122 reviews in which bypass was deemed inappropriate were associated with potentially avoidable estimated total payments of $3,818,722. CONCLUSIONS: In this cross-site expert peer review study, 40% of lower extremity bypasses were deemed premature and, therefore, potentially avoidable, primarily owing to a lack of medical and lifestyle management before surgery. Reviews deemed inappropriate were associated with approximately $4 million in potentially avoidable costs. This approach could inform performance feedback among surgeons to help align clinical practice with evidence-based recommendations for the treatment of claudication.

Robotic Approach is Associated With a Lower Conversion Rate Compared to Laparoscopic Approach for Patients Undergoing Colectomy for T4b Colon Cancer. An Analysis of the National Cancer Database.

INTRODUCTION: We examined the perioperative outcomes of patients undergoing open, laparoscopic, or robotic colectomy for T4b colon cancer, as well as the clinical factors associated with conversion to an open approach and its consequences on perioperative and oncologic outcomes. METHODS: The National Cancer Database was queried for patients undergoing colectomy for cT4b colon cancer (2010-2016). Patients undergoing laparoscopic or robotic colectomy were matched using Propensity-Score analysis. Factors associated with conversion to an open approach were assessed using Logistic-regression multivariable-analysis (MVA). RESULTS: Colectomy for cT4b colon cancer was performed in 9030 patients (open: n = 6,543, robotic: n = 157, laparoscopic: n = 2330). In the propensity-matched groups, robotic approach had lower rate of conversion (12% vs 37%, P < .001), shorter hospital stays (5 vs 7-days, P = .02), and similar overall-survival (5-yr: 49% vs 39%, P = .16), compared to laparoscopic approach. Conversion to an open approach was noted in 801(32%) of the patients undergoing minimally invasive surgical colectomy (robotic n = 23(15%), laparoscopic n = 778(33%). Factors associated with lower rate of conversion on multivariable-analysis included recent year of surgery (95% CI: 0.88-.97), robotic approach (95% CI: 0.22-.56), and surgeries performed in Academic hospitals (95% CI: 0.65-.96). Conversion to an open approach was associated with higher rate of positive parenchymal margin (31% vs 25%, P = .001), higher rate of 30-day readmission (12% vs 9.5%, P = .04), and similar overall survival (5-yr: 32% vs 35%, P = .19), compared to those who had no conversion. CONCLUSION: At the National level, patients undergoing colectomy for T4b colon cancer via a robotic approach had more favorable perioperative outcomes compared to laparoscopic approach. Conversion to an open approach did not compromise long term survival, despite being associated with higher rate of positive margins and readmissions rate.

Expected changes in physician outpatient interventional practices as a result of coronavirus disease 2019 and recent changes in Medicare physician fee schedule.

OBJECTIVE: We examined the economic and practice effects of the coronavirus disease 2019 (COVID-19) pandemic and decreased Medicare physician payments on outpatient vascular interventional procedures. METHODS: A 21-point survey was constructed and sent electronically to the physician members of the Outpatient Endovascular and Interventional Society and the American Vein and Lymphatic Society. The survey responses were converted to a Likert scale and statistical analyses performed to examine the associations between the response variables and the characteristics and practice patterns of the physician respondents. RESULTS: A total of 165 physicians responded to the survey, of whom 33% were vascular surgeons, 18% were radiologists, and 15% were general surgeons. For slightly more than one half (55%), their interventional practice was limited to the office setting, with the remainder also performing procedures in an office-based laboratory (OBL), ambulatory surgery center (ASC), or hospital. Almost all respondents had performed superficial venous interventions, with slightly more than one third also performing either deep venous procedures and/or peripheral arterial interventions. The COVID-19 pandemic had affected 98% of the practices, with a staff shortage reported by 63%. The most-established physicians, those with the longest interval since training completion, were the least likely to have experienced staff shortages. Almost all (94%) the respondents expected that the recent Medicare payment changes will have a negative effect on their practice. Physicians with only an office-based practice were less likely to add a physician associate compared with those with an OBL (P = .036). More than one quarter reported that it was likely they would close or sell their interventional practice in the next 2 years and 43% reported they were planning to retire early. The anticipated ameliorative responses to the decreased Medicare physician payments included adding wound care (24%) or other clinical services (36%) to their practices, with the alternatives considered more by younger physicians (P = .002) and nonsurgeons (P = .047). Only 10% expected to convert their practices to an ASC or hybrid ASC/OBL (16%). CONCLUSIONS: The emotional and economic effects of the COVID-19 pandemic and the decreased Medicare physician reimbursement rates for vascular outpatient interventionalists have been significant. Even greater challenges for the financial viability of office practices and OBLs can be expected in the near future if additional further planned cuts are put into effect.

Concomitant Achilles Tendon Lengthening with Transmetatarsal Amputation for the Prevention of Late Forefoot Ulceration.

BACKGROUND: Late development of forefoot ulcers is a common finding after transmetatarsal amputation (TMA). The primary aim of this study was to examine whether concomitant prophylactic Achilles tendon lengthening (ATL) was associated with a reduction in the incidence of forefoot ulcers postoperatively. METHODS: A retrospective chart review was performed by 2 authors to identify patients who underwent TMA over a period of 5.5 years from January 1, 2015, through July 31, 2020. They identified 110 feet in 107 patients; the 83 patients (85 feet) who had ≥120 days of follow-up were used for the study. Follow-up was performed with telephone calls (80 patients) or during the last office visit (3 patients). Those who were contacted by telephone were asked if they developed an ulcer after healing from the original surgery. Mean follow-up time was 672 ± 258 days for the 30 feet with concomitant Achilles lengthening and 663 ± 434 days for the 55 feet without Achilles lengthening. Demographic data were analyzed for association with late development of forefoot ulceration. RESULTS: Eighty-five feet were included in the analysis. Late forefoot ulcers developed in 35% of feet that had a TMA alone (n = 55) compared with 3% of feet who received a concomitant ATL (n = 30; p < 0.001); the 2 groups had similar mean follow-up times. Mean time to ulcer development was 587 ± 420 days in the 19 patients without Achilles lengthening. Of the patients who developed late forefoot ulcers, 47% also developed osteomyelitis, and 16% went on to proximal amputation. Patients who developed forefoot ulcers were younger (55 ± 12 versus 63 ± 11 years of age; p = 0.006) than those who did not. CONCLUSIONS: ATL at the time of TMA is associated with a reduction in the risk of later development of forefoot ulcers, especially in younger patients. LEVEL OF EVIDENCE: Therapeutic Level III .

Extended anticoagulation for venous thromboembolism: A survey of the American Venous Forum and the European Venous Forum.

OBJECTIVE: Extended anticoagulation therapy should always be considered after standard treatment of an unprovoked episode of venous thromboembolism (VTE). It can also be considered for selected patients with provoked VTE. However, the evidence-based protocols suggested by some clinical guidelines and risk assessment tools to guide this practice are limited and ambiguous. The goal of the present survey research was to analyze current practices in applying extended anticoagulation therapy for patients with VTE among members of the American Venous Forum (AVF) and European Venous Forum (EVF). METHODS: An online survey was created by the AVF Research Committee. The survey consisted of 16 questions to identify the country of practice, specialty, experience of the participating physicians, and their clinical practice patterns in applying extended anticoagulation therapy for VTE patients. The survey was distributed via e-mail to the members of the AVF and EVF. RESULTS: A total of 144 practitioners, 48 AVF members (33%) and 96 EVF members (66%), participated in the survey. Most of the respondents identified themselves as vascular specialists with primary certification in vascular surgery (70%), vascular medicine or angiology (9%), and venous disease or phlebology (3%). Of the 144 respondents, 72% believed that the risk of VTE recurrence will generally overweigh the risk of bleeding for patients with unprovoked VTE. Extended anticoagulation therapy might be used by 97% of providers. Different patterns in real world clinical practice were identified. More than one half of the practitioners estimated the VTE recurrence and bleeding risk subjectively. The antithrombotic drugs most commonly used for secondary prophylaxis were rivaroxaban, apixaban, warfarin, dabigatran, and aspirin, in decreasing order of frequency. Among the reasons selected for not regularly considering extended anticoagulation therapy were the lack of specific clinical practice guidelines (24%), lack of reported evidence (9%), and absence of valid VTE and/or bleeding risk prediction calculators (8%). Twelve participants (8%) stated that extended anticoagulation therapy would not be beneficial for most patients with VTE. Ten participants (7%) indicated that prescribing extended anticoagulation therapy was outside the scope of their specialty. CONCLUSIONS: Different practice patterns exist regarding extending anticoagulation therapy beyond the standard treatment for patients with VTE. Major gaps in knowledge remain a serious challenge at least partially explaining the inaccuracy and inconsistency in long-term VTE management. Appropriately designed studies are needed to evaluate risk stratification tools when contemporary best medical therapy is used, accurately predict VTE recurrence and its long-term outcomes, and tailor safe and effective secondary prophylaxis.

National Trends and Perioperative Outcomes of Robotic-assisted Hepatectomy in the USA: A Propensity-score Matched Analysis from the National Cancer Database.

BACKGROUND: A paucity of data exists on the national use of robotic hepatectomy. We assessed national trends and perioperative outcomes of robotic hepatectomy in the USA. In addition, factors associated with use of the robotic approach were analyzed. METHODS: The National Cancer Database (NCDB) was queried for patients undergoing hepatectomy from 2010 to 2016. Patients undergoing total hepatectomy for transplant were excluded. Factors associated with the use of the robotic approach were assessed using logistic regression multivariable analysis. Propensity-score analysis was performed (robotic vs. laparoscopic and robotic vs. open approaches), and perioperative outcomes were compared between the matched groups. RESULTS: The robotic approach was used in 287 patients (110 hospitals). Utilization of the robotic approach increased significantly on the national level from 0.8% in 2010 to 4.1% in 2016 (P<0.001). The number of hospitals performing a minimum of one robotic hepatectomy per year increased from 8 in 2010 to 35 in 2016. The median hospital length of stay was 4 days (IQR 3-6), 30-day readmission rate was 5%, and 30-day/90-day mortality rates were 3%/4%. Factors associated with using robotic approach were African-American race (95% CI 1.02-2.11), recent year of surgery (95% CI 1.11-1.32), HCC histology (95% CI 1.01-52.03), tumor size (95% CI 0.87-0.96), and early-stage tumor (Stage I-II, 95% CI 1.27-3.99). On propensity-matched analysis, there were no differences between robotic and open approaches (n=184 each group) in 30-day readmission (5% vs. 7%, P=0.651), 30-day mortality (2% vs. 4%, P=0.106), 90-day mortality (3% vs. 7%, P=0.080), or 5-year overall survival (58% vs. 43%, P=0.211). However, the robotic approach was associated with a significantly shorter hospital stay (median: 4 vs. 6 days, P<0.001). There were no differences between matched groups of patients undergoing robotic and laparoscopic approaches (n=182 in each group) in perioperative outcomes or length of hospital stay. CONCLUSION: National use of robotic-assisted hepatectomy has increased by fivefold over the seven-year study period. It was associated with a shorter hospital length of stay compared to the open approach without compromising perioperative outcomes or survival.

Ultrasound-guided foam sclerotherapy is safe and effective in the management of superficial venous insufficiency of the lower extremity.

BACKGROUND: Superficial venous disease of the lower extremity has a significant impact on quality of life. Both truncal and tributary vein reflux contribute to this disease process. Endovenous foam sclerotherapy is a widely used technique throughout the world for the management of superficial venous reflux and ultrasound guidance improves its safety and efficacy. METHODS: A PubMed search for ultrasound-guided foam sclerotherapy (UGFS) was conducted and all abstracts were reviewed to identify clinical trials and systematic reviews for a full-text analysis. Additional articles were also identified through searching the references of the selected studies. RESULTS: The production of foam for sclerotherapy in a 1:3 or 1:4 ratio of air to sclerosant is optimal in a low silicone, low-volume syringe system. Physiologic gas may decrease any side effects, with the trade-off of decreased foam stability. Proper technique with appropriate sterility and cleansing protocols are paramount for safe and effective treatment. The technical success of UGFS for great saphenous vein disease is inferior to endothermal and surgical modalities and retreatment is more common. However, the clinical improvement in patient-reported quality of life is similar between these three modalities. When used for tributary veins in combination with endothermal approaches of the truncal veins, UGFS has high rates of success with excellent patient satisfaction. UGFS has demonstrated an excellent safety profile comparable with or superior to other modalities. CONCLUSIONS: With proper technique, UGFS is safe and effective for the management of superficial venous disease.

The need for participation in the development and critical review of recommendations for infection control policies involving vascular ultrasound.

Recently reported guidelines from the Society of Diagnostic Medical Sonography regarding disinfection of ultrasound probes and infection control policies for ultrasound procedures conflict with accepted clinical norms in vein practices and recommendations from the American Institute for Ultrasound in Medicine. We have provided a review of these conflicting policy recommendations and new proposed practice recommendations and a call for physicians who perform ultrasound-guided procedures to be involved in the process of development and critical review of societal recommendations.

The academic experience in distance (virtual) rounding and education of emergency surgery during COVID-19 pandemic.

BACKGROUND: To cope with COVID-19 pandemic control precautions, many surgical residency programs have adopted a Declared Health Emergency rotation to minimize exposure to the COVID-19. We evaluated the experience and educational value of virtual education activities by reviewing the perceptions of the Declared Health Emergency rotation participants through survey questionnaire analysis. METHODS: Participants of the Declared Health Emergency rotation virtual educational activities were asked to complete a survey questionnaire describing their perception and experience. RESULTS: The survey response rate was 100% (faculty, n = 13; residents, n = 8; nurse practitioners/physician assistants, n = 4). The majority reported that virtual activities required minimal technical skills (n = 17, 68%). Compared to the traditional in-person conferences before the pandemic, the majority reported that they participated in virtual rounds more often or the same (n = 22, 88%), that the overall level and quality of interactions were the same or better (n = 19, 76%), and that the knowledge gained was the same or more (n = 22, 88%). All respondents reported that virtual conferences educational objectives were met. CONCLUSION: The quality of education and the knowledge gain during the virtual educational activities are equivalent or better than in the traditional face-to-face activities. The use of technology in virtual educational activities is a practical and convenient approach to achieve the desired educational objectives during and potentially after the COVID-19 pandemic.

Alternatives surgical training approaches during COVID-19 pandemic.

IMPORTANCE: Coping with the COIVD-19 global-pandemic major changes in healthcare and educational operational policies, mandates the implementation of alternative surgical curriculum objects (components) to replace some of the traditional face-to-face activities. OBJECTIVE: The objective of the study is to review and discuss various alternative curriculum objects (components) that can be used to restructure conventional surgical training curricula during the Declared Healthcare Emergency surgery rotations. The goal is to identify and recommend effective alternative educational activities that are compliant with the new social physical distancing regulations. EVIDENCE REVIEW: Various curricular components and objects were examined. The educational value of the curriculum objects is studied and analyzed in terms of feasibility, knowledge gain/learning effectiveness, the need for facilitation or feedback, and the evaluation. Several curriculum objects were proposed with description of their value and applications. FINDINGS: The selected and proposed activities include scenario-based MCQ writing exercises, video-based surgical skills interactive training, online learning modules, virtual rounding, reflection assignments, surgical skills simulation training, research education, and medical education learning. Their educational value is described and scaled. CONCLUSION: There is urgent and challenging need for surgical training using additional alternative curriculum objects (components). Working with the available resources and experiences is crucial to maximize the learning outcomes. Distance (online) education and educational technology tools and concepts provide a spectrum of valuable educational activities. Further work and studies are needed to optimize their utility.

Specialty differences in resident resilience and burnout - A national survey.

BACKGROUND: Burnout is widespread among resident physicians, but higher resilience is associated with lower burnout. This study characterizes the relationship between resilience and burnout in medical (MR) and surgical (SR) resident physicians. METHODS: A cross-sectional survey was distributed to all ACGME-accredited residency programs with the Connor-Davidson Resilience Scale and Abbreviated Maslach Burnout Inventory. RESULTS: Of the 682 respondents, both Medical and Surgical Residents with higher resilience had lower burnout. Higher resilience was seen in Surgical Residents who were men, had greater family support, more residency program support, and enjoyed greater autonomy. Burnout was greater in women, Caucasians, those in an academic setting, and with less autonomy and program support. Burnout was similar among the medical and surgical groups, but surgical trainees had higher resilience. Overall, family and institutional support was associated positively with high resilience and decreased burnout. CONCLUSIONS: Increasing resilience and program support can decrease burnout, especially for high-risk subgroups.

Removing abuse-prone prescription medication from fueling the national opioid crisis through community engagement and surgeon leadership: results of a local drug take-back event.

BACKGROUND: To address the national opioid and death from overdose crisis in the United States, take-back programs were created to collect and properly dispose of unused abuse-prone drugs. METHODS: Surgeons at Central Michigan University College of Medicine led a community prescription medication take-back drive, administered surveys, characterized event participant demographics, prescription indications, and type and quantity of medications dropped off for disposal. RESULTS: A total of 74,363 dosing units of unused medication were brought in from the homes of 104 event participants. Returned opioids were often prescribed after surgery. Hydrocodone was collected most. Unused opioids were frequently available in homes with children or youth. Collected opioids and benzodiazepines alone had an estimated trademark retail value of over $20,000. CONCLUSION: This surgeon-led public health initiative helped properly dispose a significant amount of unneeded abuse-prone prescription medicine. It highlighted the presence of excess opioid prescribing in a typical Midwestern community. Issues related to improved physician prescribing, utility of take-back drives, and proper drug disposal to avoid misappropriation and abuse by younger generations are discussed.
