What is the patient experience of surgical care during the coronavirus disease 2019 (COVID-19) pandemic? A mixed-methods study at a single institution.

BACKGROUND: The coronavirus disease 2019 outbreak has spread worldwide and has resulted in hospital restrictions. The perceived impact of these practices on patients undergoing essential surgeries is less understood. METHODS: Adult (≥18 years) patients who underwent medically necessary surgical procedures spanning multiple surgical specialties from March 23, 2020, to April 24, 2020, during the coronavirus disease 2019 pandemic were identified as eligible for a phone survey. Survey responses were analyzed using a mixed-methods approach involving descriptive statistics and thematic analysis of coded and annotated survey results. RESULTS: Of the 212 patients who underwent medically necessary surgical procedures during the coronavirus disease 2019 pandemic, the majority of these patients were male (61.3%), White (83.5%), married or with a domestic partner (68.9%), and underwent oncologic procedures (69.3%). Of the 46 patients (21.7%) who completed the survey, the majority of these patients indicated that coronavirus disease 2019 pandemic restrictions had no impact on their inpatient hospital stay and were satisfied with their decision to proceed with surgery. Severity of patient condition (44.4%), the risk/benefit discussion with the surgeon (24.4%), and coronavirus disease 2019 education and testing (19.5%) were the most important factors in proceeding with surgery during the pandemic; 34.4% of patients said their inpatient postoperative course was negatively affected by the lack of visitors. CONCLUSION: Medically necessary, time-sensitive surgical procedures, as determined by the surgeon, can be performed during a pandemic with good patient satisfaction provided there is an appropriate discussion between the surgeon and patient about the risks and benefits.

Impact of COVID-19 Restrictions on Demographics and Outcomes of Patients Undergoing Medically Necessary Non-Emergent Surgeries During the Pandemic.

BACKGROUND: The COVID-19 pandemic has resulted in large-scale healthcare restrictions to control viral spread, reducing operating room censuses to include only medically necessary surgeries. The impact of restrictions on which patients undergo surgical procedures and their perioperative outcomes is less understood. METHODS: Adult patients who underwent medically necessary surgical procedures at our institution during a restricted operative period due to the COVID-19 pandemic (March 23-April 24, 2020) were compared to patients undergoing procedures during a similar time period in the pre-COVID-19 era (March 25-April 26, 2019). Cardinal matching and differences in means were utilized to analyze perioperative outcomes. RESULTS: 857 patients had surgery in 2019 (pre-COVID-19) and 212 patients had surgery in 2020 (COVID-19). The COVID-19 era cohort had a higher proportion of patients who were male (61.3% vs. 44.5%, P < 0.0001), were White (83.5% vs. 68.7%, P < 0.001), had private insurance (62.7% vs. 54.3%, p 0.05), were ASA classification 4 (10.9% vs. 3%, P < 0.0001), and underwent oncologic procedures (69.3% vs. 42.7%, P < 0.0001). Following 1:1 cardinal matching, COVID-19 era patients (N = 157) had a decreased likelihood of discharge to a nursing facility (risk difference-8.3, P < 0.0001) and shorter median length of stay (risk difference-0.6, p 0.04) compared to pre-COVID-19 era patients. There was no difference between the two patient cohorts in overall morbidity and 30-day readmission. CONCLUSIONS: COVID-19 restrictions on surgical operations were associated with a change in the racial and insurance demographics in patients undergoing medically necessary surgical procedures but were not associated with worse postoperative morbidity. Further study is necessary to better identify the causes for patient demographic differences.

Hiatal Hernia after Esophagectomy: An Underappreciated Complication?

BACKGROUND: The natural history of hiatal herniation of small and/or large bowel post-esophagectomy (HHBPE) in the current era of improving long-term survival and evolving surgical technique is unknown. The aim of this study was to describe the rate and risk factors of HHBPE at our hospital. METHODS: Patients undergoing esophagectomy between January 2011 and June 2017 were included if both follow-up information and axial imaging were available beyond 3 months post-esophagectomy. Patient characteristics, disease information, and treatment factors were all included in univariate analysis comparing patients with and without HHBPE, and multivariate regression was used to identify significant independent risk factors associated with HHBPE. RESULTS: Of 310 esophagectomy patients analyzed, 258 patients were included in the study, with 79 patients (31%) showing evidence of an HHBPE and an overall median follow-up of 24 months; 44 of 79 patients (56%) had symptoms possibly referable to HHBPE and 17 of 79 patients (22%) underwent surgical repair. On univariate analysis, neoadjuvant therapy (n = 176), higher clinical stage, minimally invasive approach (n = 154), and transhiatal esophagectomy (n = 189) were significant predictors of HHBPE (p < 0.05). On multivariate analysis, neoadjuvant therapy and transhiatal approach remained significant independent predictors (p < 0.05). The rate of HHBPE was 44% in the 131 patients (51%) that had both factors. CONCLUSIONS: HHBPE in the current era of neoadjuvant therapy and minimally invasive esophagectomy is common. HHBPE can cause gastrointestinal symptoms, but operation to repair HHBPE is uncommon on intermediate follow-up. Additional study and long-term follow-up are required to fully assess the impact of HHBPE and to potentially modify surgical practice to prevent or minimize HHBPE.

Nationwide Analysis of 30-Day Readmissions After Esophagectomy: Causes, Costs, and Risk Factors.

BACKGROUND: Postsurgical readmissions are an increasingly scrutinized marker of health care quality. We sought to estimate the rate, risk factors, causes, and costs associated with readmissions after esophagectomy in a large, nationally representative cohort. METHODS: We studied patients from the Nationwide Readmissions Database undergoing esophagectomy from 2010 to 2014. Data were collected on the prevalence and indications for readmission within 30 days as well as the hospital-, procedure-, and patient-level risk factors as determined by multivariable logistic regression. RESULTS: Among 13,282 cases, the rate of 30-day readmission was 19.4%, with the most common indications for readmission being pulmonary (20.6%) and gastrointestinal complications (20%). Median cost of readmission was $9660 (interquartile range, $5392 to $20,447), and pulmonary complications accounted for the greatest total cost burden at 25.8% of all readmission-related costs. Independent risk factors for readmission on multivariable analysis included perioperative blood transfusion (adjusted odds ratio [AOR] 1.33; 95% confidence interval [CI], 1.08 to 1.65; P = .008), discharge to a nursing facility (AOR 1.83; 95% CI, 1.41 to 2.39; P < .001), high illness severity based on All Patients Refined Diagnosis-Related Groups scoring (AOR 1.49; 95% CI, 1.21 to 1.84; P < .001), chronic renal failure (AOR 1.61; 95% CI, 1.13 to 2.29; P = .009), and comorbid drug abuse (AOR 2.19; 95% CI, 1.08 to 4.41; P = .029). CONCLUSIONS: Nearly 1 in 5 patients undergoing esophagectomy are readmitted within 30 days of discharge, at a median cost of $9660 per readmission. Pulmonary complications account for the greatest number of readmissions and the greatest total cost burden. Targeting the causes of readmission, especially pulmonary causes, may help significantly reduce the total morbidity and health care costs associated with esophagectomy.

The Malnourished Patient With Obesity: A Unique Paradox in Bariatric Surgery.

BACKGROUND: Hypoalbuminemia is a known risk factor for poor outcomes following surgery. Obesity can be associated with modest to severe malnutrition. We evaluated the impact of hypoalbuminemia on surgical outcomes in patients with obesity undergoing elective bariatric surgical procedures. MATERIALS AND METHODS: The 2015 metabolic and bariatric surgery accreditation and quality improvement program database was queried. Patients ≥ 18 y with body mass index ≥35 undergoing bariatric surgery were included. Revision procedures were excluded. Patients were classified by albumin level (albumin ≥3.5 g/dL [normal], 3.49-3.0 g/dL [mild], 2.99-2.5 g/dL [moderate], and <2.5 g/dL [severe]). Independent logistic regression models were developed to estimate the adjusted odds of (1) death or serious morbidity (DSM); (2) mild to moderate complications; (3) severe complications; and (4) 30-d readmissions by albumin level. In addition, effect modification by >10% weight loss was examined. RESULTS: A total of 106,577 patients were included in the study. Over 6% of patients had hypoalbuminemia. Fifty-five percent of complications were severe as categorized by the Clavien-Dindo classification. Patients with mild hypoalbuminemia had 20% increased odds of DSM (95% confidence interval: 1.1-1.4). There was increasing likelihood of DSM with severe hypoalbuminemia. Patients with mild hypoalbuminemia had 20% increased odds of 30-d readmission (confidence interval: 1.1-1.3). A >10% weight loss modified the effect of moderate to severe hypoalbuminemia on DSM. CONCLUSIONS: More than 6% of patients with obesity undergoing bariatric surgery are malnourished. Hypoalbuminemia is an important and modifiable risk factor for postoperative adverse outcomes following bariatric surgery. Preoperative weight loss >10% combined with moderate to severe hypoalbuminemia is synergistic for high rates of DSM and should be addressed before proceeding with bariatric surgery.

The Association of Body Mass Index with Postoperative Outcomes After Elective Paraesophageal Hernia Repair.

PURPOSE: To evaluate the association between body mass index (BMI) and postoperative outcomes in elective paraesophageal hernia (PEH) repairs. METHODS: A retrospective review of patients who underwent elective PEH repair in the ACS NSQIP database (2005-2015) was performed. Patients were stratified into BMI groups (< 18.5, 18.5-24.9, 25.0-29.9, 30.0-34.9, 35-39.9, and ≥ 40.0 kg/m2) according to the World Health Organization classification criteria. A multivariable logistic regression model was developed to characterize the association between BMI class and outcomes, including readmission, reoperation, postoperative complications, and mortality. RESULTS: The median (IQR) age of the 9641 patients who met inclusion criteria was 64 (55-72) and 72.7% were women. Across each BMI class, age, race, gender, type of procedure, frailty index, smoking, and ASA class varied (p < 0.05). Underweight patients (BMI < 18.5 kg/m2) had an increased risk of mortality (OR = 6.35, p < 0.05). Patients with a BMI 35-39.9 kg/m2 (OR = 0.65, p < 0.05) and ≥ 40 kg/m2 (OR = 0.36, p < 0.001) were associated with a decreased risk for readmissions. CONCLUSION: Underweight patients have an increased risk for postoperative mortality after elective PEH repair. Higher BMI was associated with a diminished risk for readmission, but not for mortality, reoperations, or overall complications.

Resection of gallbladder remnants after subtotal cholecystectomy: presentation and management.

BACKGROUND: Subtotal cholecystectomy (SC) involves removal of a portion of the gallbladder typically due to hazardous inflammation. While this technique reliably prevents common bile duct (CBD) injury, future procedures can be required if the gallbladder remnant becomes symptomatic. The morbidity associated with resection of gallbladder remnants in patients that previously underwent SC is reviewed. METHODS: Records for patients having undergone redo cholecystectomy for symptomatic gallbladder remnants in a tertiary care system from 2013 to 2017 were retrospectively reviewed. RESULTS: Fourteen patients underwent repeat cholecystectomy. Five surgeons dictated the initial procedure as a subtotal cholecystectomy. All patients returned with symptomatic cholelithiasis between zero months and seven years after the index cholecystectomy. Redo cholecystectomy was attempted laparoscopically in two patients but ultimately required an open approach in all. One patient had a recognized CBD injury requiring a hepaticojejunostomy, and a second patient had a minor wound infection. Symptoms resolved in 13/14 patients. CONCLUSIONS: Redocholecystectomy (RC) for gallbladder remnants has been detailed in case reports, but no sizable North American series have been presented. These results illustrate a drawback to the reconstituting technique of SC. RC effectively resolves symptoms but requires adherence to safe principles of cholecystectomy and is one indication for an open approach.

Barium upper GI series in adults: a surgeon's perspective.

Barium upper GI series performed by an interested and competent radiologist is still a very useful study to evaluate a variety of esophagogastric disorders. It usually provides information complementary to upper endoscopy and other foregut studies. Barium upper GI series is an important part of the diagnostic workup for gastroesophageal reflux disease, hiatal hernia, and esophageal motility disorders including achalasia. It is also an important part of the follow-up after operation for these common problems and after other operations such as resection or bariatric surgery. The GI radiologist should be an important member of the foregut surgery team.

Laparoscopic Heller Myotomy vs Per Oral Endoscopic Myotomy: Patient-Reported Outcomes at a Single Institution.

BACKGROUND: Although laparoscopic Heller myotomy (LHM) has been the standard of care for achalasia, per oral endoscopic myotomy (POEM) has gained popularity as a viable alternative. This retrospective study aimed to compare patient-reported outcomes between LHM and POEM in a consecutive series of achalasia patients with more than 1 year of follow-up. STUDY DESIGN: We reviewed demographic and procedure-related data for patients who underwent either LHM or POEM for achalasia between January 2011 and May 2016. Phone interviews were conducted assessing post-procedure achalasia symptoms via the Eckardt score and achalasia severity questionnaire (ASQ). Demographics, disease factors, and survey results were compared between LHM and POEM patients using univariate analysis. Significant predictors of procedure failure were analyzed using univariate and multivariate analysis. RESULTS: There were no serious complications in 110 consecutive patients who underwent LHM or POEM during the study period, and 96 (87%) patients completed phone surveys. There was a nonsignificant trend toward better patient-reported outcomes with POEM. There were significant differences in patient characteristics including sex, achalasia type, mean residual lower esophageal pressure (rLESP), and follow-up time. The only univariate predictors of an unsatisfactory Eckardt score or ASQ were longer follow-up and lower rLESP, with follow-up length being the only predictor on multivariate analysis. CONCLUSIONS: There were significant demographic and clinical differences in patient selection for POEM vs LHM in our group. Although the 2 procedures have similar patient-reported effectiveness, subjective outcomes seem to decline as a result of time rather than procedure type.

"How To" Videos Improve Residents Performance of Essential Perioperative Electronic Medical Records and Clinical Tasks.

OBJECTIVE: The ability to use electronic medical records (EMR) is an essential skill for surgical residents. However, frustration and anxiety surrounding EMR tasks may detract from clinical performance. We created a series of brief, 1-3 minutes "how to" videos demonstrating 7 key perioperative EMR tasks: booking OR cases, placing preprocedure orders, ordering negative-pressure wound dressing supplies, updating day-of-surgery history and physical notes, writing brief operative notes, discharging patients from the postanesthesia care unit, and checking vital signs. Additionally, we used "Cutting Insights"-a locally developed responsive mobile application for surgical trainee education-as a platform for providing interns with easy access to these videos. We hypothesized that exposure to these videos would lead to increased resident efficiency and confidence in performing essential perioperative tasks, ultimately leading to improved clinical performance. METHODS: Eleven surgery interns participated in this initiative. Before watching the "how to" videos, each intern was timed performing the aforementioned 7 key perioperative EMR tasks. They also underwent a simulated perioperative emergency requiring the performance of 3 of these EMR tasks in conjunction with 5 other required interventions (including notifying the chief resident, the anesthesia team, and the OR coordinator; and ordering fluid boluses, appropriate laboratories, and blood products). These simulations were scored on a scale from 0 to 8. The interns were then directed to watch the videos. Two days later, their times for performing the 7 tasks and their scores for a similar perioperative emergency simulation were once again recorded. Before and after watching the videos, participants were surveyed to assess their confidence in performing each EMR task using a 5-point Likert scale. We also elicited their opinions of the videos and web-based mobile application using a 5-point scale. Statistical analyses to assess for statistical significance (p ≤ 0.05) were conducted using paired t-test for parametric variables and a Wilcoxon matched-pair test for nonparametric variables. SETTING: Hospital of the University of Pennsylvania, Philadelphia, PA (a quaternary teaching hospital within the University of Pennsylvania Health System). PARTICIPANTS: Eleven out of 15 interns (12 entered and 11 completed the study) from our categorical and preliminary general surgery residency programs during the 2016 academic year. RESULTS: Before exposure to the brief "how to" videos, 6 of 11 interns were unable to complete all 7 EMR tasks; after exposure, all 11 interns were able to complete all 7 EMR tasks. Moreover, interns' times for each task improved following exposure. Interns self-reported improved confidence in booking an OR case (4 ± 0.9 vs. 4.7 ± 0.6, p = 0.05), ordering negative-pressure wound therapy supplies (3.1 ± 1.6 vs. 4.5 ± 0.7, p < 0.05), writing a brief operative note (3.7 ± 1.2 vs. 4.6 ± 0.7, p = 0.05), discharging patients from the postanesthesia care unit (3.3 ± 1.0 vs. 4.4 ± 0.8, p < 0.05), checking vital signs (2.5 ± 1.4 vs. 4.5 ± 0.8, p ≤ 0.01), and performing necessary EMR tasks during an emergency situation (2.4 ± 0.8 vs. 4.6 ± 0.7, p ≤ 0.0001). Participants also demonstrated a significant improvement in average clinical score on the emergency simulations (5.2 ± 1.7 vs. 6.6 ± 0.9, p < 0.05). Interns' opinions of the videos and the mobile phone application were favorable. CONCLUSIONS: In our group of 11 surgery interns, exposure to a series of short "how to" videos led to increased confidence and shortened times in performing 7 essential EMR tasks. Additionally, during a simulated perioperative emergency, EMR tasks were performed significantly faster. Clinical performance also improved significantly following exposure to the videos. This just-in-time educational intervention could improve workflow efficiency and clinical performance, both of which may ultimately enhance perioperative patient safety.

Resource Usage Implementing the Surgical Resident Prep Curriculum at a Single Institution.

OBJECTIVE: The Resident Prep Curriculum (RPC), published in 2014 and developed as a collaboration of the American College of Surgeons, Association of Program Directors in Surgery, and the Association for Surgical Education, was designed to improve the quality and consistency of medical student preparation for surgical residency. We aim to assess the feasibility of and resource usage for implementation of this curriculum at our institution. DESIGN: Our institution expanded upon a pre-existing 2-week surgical preparatory course, adding modules designed to meet the goals and objectives of the RPC. We performed an evaluation of the resources required for these additions, namely time, logistics and incremental cost. SETTING: The course took place at the Perelman School of Medicine, which is a large, academic medical center affiliated with the Hospital of the University of Pennsylvania. RESULTS: Our course satisfied each of the six domains outlined in the RPC. In 2015, 22 students were enrolled in the course. It was run over a consecutive 4-week period in the spring of 2015, with 9 full and 9 half days. To meet the needs of the Curriculum, approximately 33 hours (38%) were spent in the classroom, 34 hours (39%) in a simulation center, and 20 hours (23%) in the anatomical laboratory. Seventy faculty-hours (from 5 disciplines) and 73 resident-hours (double-counting for cotaught modules) were required to support the course. Besides room availability, funding was required for certain aspects of the course such as cadavers, dedicated anatomy teaching, and the costs of supplies in the simulation center. There is also a cost associated with the use of the Penn Medicine Simulation Center. Taking these into account, the total cost of implementing the curriculum amounted to $30,627.10. CONCLUSION: The implementation of the RPC was feasible but relied heavily upon faculty/resident time. As a result of the success of this initiative, our medical school seeks to expand the idea across multiple specialties.

Surgical management of obesity.

Obesity is a spreading epidemic associated with significant morbidity and mortality with a prevalence of over 36% worldwide. In the face of a growing epidemic, increasing medical costs, and the disappointing limitations of medical and lifestyle modification bariatric surgery was found to consistently lead to significant weight loss and improvement in obesity-associated comorbidities when compared to non-surgical interventions. Bariatric procedures fall within three basic categories: restrictive procedures, malabsorptive procedures, and procedures that combine both restrictive and malabsorptive mechanisms. Four major procedures are currently performed (most often laparoscopically): Roux-en-Y gastric bypass, biliopancreatic diversion with duodenal switch, adjustable gastric banding, and sleeve gastrectomy. Although the laparoscopic Roux-en-Y gastric bypass was the most frequently performed bariatric procedure, the laparoscopic sleeve gastrectomy has since become the most popular. Bariatric surgery currently has similar mortality rates to standard general surgical operations. Morevoer, bariatric surgery reduces mortality by the improvement and remission of obesity-related comorbidities. Newer minimally-invasive weight loss procedures and endoscopic methods continue to evolve as we expand our understanding of the intricacies of obesity and the effects of currently available surgical treatments.

Implementation of a systematic culturing program to monitor the efficacy of endoscope reprocessing: outcomes and costs.

BACKGROUND AND AIMS: In 2015, the U.S. Food and Drug Administration and Centers for Disease Control and Prevention (CDC) issued guidance for duodenoscope culturing and reprocessing in response to outbreaks of carbapenem-resistant Enterobacteriaceae (CRE) duodenoscope-related infections. Based on this guidance, we implemented best practices for reprocessing and developed a systematic process for culturing endoscopes with elevator levers. The aim of this study is to report the outcomes and direct costs of this program. METHODS: First, clinical microbiology data from 2011 to 2014 were reviewed retrospectively to assess for possible elevator lever-equipped endoscope-related CRE infections. Second, a program to systematically culture elevator lever-equipped endoscopes was implemented. Each week, about 25% of the inventory of elevator lever-equipped endoscopes is cultured based on the CDC guidelines. If any cultures return bacterial growth, the endoscope is quarantined pending repeat culturing. The costs of the program, including staff time and supplies, have been calculated. RESULTS: From 2011 to 2014, none of 17 patients with documented CRE infection had undergone ERCP or endoscopic ultrasound in the previous 36 months. From June 2015 to September 2016, 285 cultures were performed. Three (1.1%) had bacterial growth, 2 with skin contaminants and 1 with an oral contaminant. The associated endoscopes were quarantined and reprocessed, and repeat cultures were negative. The total estimated cost of our program for an inventory of 20 elevator lever-equipped endoscopes was $30,429.60 per year ($1521.48 per endoscope). CONCLUSIONS: This 16-month evaluation of a systematic endoscope culturing program identified a low rate of positive cultures after elevator lever endoscope reprocessing. All positive cultures were with non-enteric microorganisms. The program was of modest cost and identified reprocessing procedures that may have led to a low rate of positive cultures.

Surgical Management of Early-Stage Esophageal Adenocarcinoma Based on Lymph Node Metastasis Risk.

BACKGROUND: In early-stage esophageal adenocarcinoma (EAC), esophagectomy improves staging but also increases mortality compared with endoscopic resection. Our objective was to quantify esophagectomy mortality and lymph node metastasis (LNM) risk in early-stage EAC to improve surgical treatment allocation. METHODS: We identified National Cancer Database (2004-2014) patients with nonmetastatic, Tis, T1a, or T1b EAC who had primary surgical resection and microscopic examination of at least 15 lymph nodes. Univariate and multivariable logistic regression identified predictors of LNM. Cox regression identified predictors of death. The Kaplan-Meier method predicted overall survival (OS). RESULTS: In 782 patients, LNM rates were: all patients 13.8%, Tis 0%, T1a 3.6%, T1b 23.4%. Independent predictors of LNM were submucosal invasion, lymphovascular invasion (LVI), decreasing differentiation, and tumor size ≥ 2 cm (P < 0.05). For T1a tumors with poor differentiation or size ≥ 2 cm, LNM rates were 10.2 and 6.7%, respectively; 90-day mortality was 3.1%. The LNM rate in well differentiated T1b tumors < 2 cm was 4.2%; 90-day mortality was 6.0%. Estimated 5-year OS was 80.2% versus 64.4% (T1a vs. T1b). LNM increased risk of death for T1a (hazard ratio [HR] 8.52, 95% confidence interval [CI] 3.13-23.22, P < 0.001) and T1b tumors (HR 2.52, 95% CI 1.59-4.00, P < 0.001). CONCLUSIONS: In T1a EAC with poor differentiation or size ≥ 2 cm, esophagectomy should be considered, whereas in T1b EAC with low-risk features (well-differentiated T1b EAC < 2 cm without LVI), endoscopic resection may be sufficient. Treatment guidelines for early-stage EAC should include all high-risk tumor features for LNM and stage-specific esophagectomy mortality.

Curriculum Using the In-Situ Operating Room Setting.

OBJECTIVE: The American College of Surgeons/Association of Program Directors in Surgery is a comprehensive, simulation-based curriculum for General Surgery residents which exists in 3 phases. While phases 1 and 2 deal with core skills and advanced procedures respectively, phase 3 targets team-based skills. To date, the 3rd phase of this curriculum has not seen wide scale implementation. This is a pilot study to verify the feasibility of implementing the phase 3 curriculum in the in-situ setting. DESIGN: In our initial attempt to implement Phase 3 at our institution, we chose to perform the training in an in-situ setting within an operating room (OR) at our main hospital, despite our having a separate simulation center. By choosing the in-situ OR environment for this training we were able to minimize concerns regarding resident and faculty availability and able to successfully complete 8 separate sessions during the academic year. During 7 sessions, 2 separate scenarios were performed while a single scenario was performed in 1 session. This single session was excluded from analysis, leaving a total of 14 scenarios to evaluate. The unique scenarios included laparoscopic crisis, postoperative myocardial infarction, anaphylaxis, and postoperative hypotension. All sessions were audiovisually recorded. In order to evaluate the effect of the training, the videos were viewed by 3 independent reviewers and all surgery, anesthesia and nursing participants were rated using the NOTECHs II scale. Degree of inter-rater agreement was established. The difference between the first and second simulations on the same day was then assessed. In addition, participant opinions of the simulations were assessed through electronic surveys following the training. SETTING: Tertiary Care University Hospital. PARTICIPANTS: We performed a total of 8 sessions, for a total of 15 scenarios. Eight surgery residents at the postgraduate year 1 (PGY1)-PGY3 level, 16 anesthesia residents at the PGY3-PGY4 level, 16 nurses and 13 ancillary staff participated. RESULTS: From the first to the second scenario, the total team NOTECHs II score increased from 69.4 ± 1.4 to 77.3 ± 0.5 (p = 0.007). The NOTECHs II scores for each subteam also improved, from 24.2 ± 0.6 to 26.4 ± 0.5 (p = 0.007) for surgery residents, 23.7 ± 0.9 to 26.7 ± 0.4 (p = 0.03) for anesthesia, and 21.6 ± 0.3 to 24.3 ± 0.5 (p = 0.01) for nursing. The inter-rater reliability as measured by Kendall's coefficient of concordance was modest for the whole team score. Most of the participant responses were either favorable or strongly favorable. CONCLUSION: The in-situ OR environment is both a unique and effective setting to perform team-based training. Furthermore, training in the in-situ setting minimizes or removes many of the logistic issues involved in designing and implementing team-based training curricula for general surgery residency programs. However, we found that administrative and departmental (surgery, anesthesia, and nursing) "buy in" as well as protected faculty time for education were all necessary for in-situ training to be successful. NOTECHs II is an established scale for the evaluation of teams in this simulation setting and appears to be a valid tool based on the results of this study. However, further assessment of inter-rater reliability as well as improved training of evaluators are necessary to determine if inter-rater reliability can improve.

Impact of body mass index on open ventral hernia repair: A retrospective review.

BACKGROUND: A large proportion of patients presenting for ventral hernia repair are obese. It remains unclear, however, whether the degree of obesity is an independent risk factor for adverse outcomes after ventral hernia repair. This study aims to characterize the influence of body mass index class on postoperative complications after open ventral hernia repair. METHODS: A retrospective analysis was conducted using data from the database of the American College of Surgeons National Surgical Quality Improvement Program from 2005 to 2015. Patients were stratified into 7 body mass index classes, as well as by type of hernia (reducible versus strangulated) and time of repair (initial versus recurrent). We determined the relationships between body mass index class and patient demographics, comorbidities, and risk of perioperative complications. RESULTS: Our cohort consisted of 102,191 patients, 58.5% of whom were obese. When stratified by body mass index class, higher classes were associated with all postoperative complications (P < .0001) with a steady increase in complication rates with increasing body mass index class. Patients with strangulated hernias had greater complication rates than those with reducible hernias (P < .0001). Patients with recurrent hernias also had greater complication rates than those with initial hernias (P < .0001). CONCLUSION: Increased body mass index is a risk factor for operative, medical, and respiratory complications after open ventral hernia repair. Patients with body mass index >40 kg/m2 have greater than twice the risk for complications with odds ratios increasing with increasing body mass index class. Strategies to encourage weight loss may need to be considered seriously prior to open ventral hernia repair, especially for patients with body mass index >40 kg/m2.

Integration of Hands-On Team Training into Existing Curriculum Improves Both Technical and Nontechnical Skills in Laparoscopic Cholecystectomy.

OBJECTIVE: Nontechnical skills are an essential component of surgical education and a major competency assessed by the ACGME milestones project. However, the optimal way to integrate nontechnical skills training into existing curricula and then objectively evaluate the outcome is still unknown. The aim of this study was to determine the effect laparoscopic team-based task training would have on the nontechnical skills needed for laparoscopic surgery. DESIGN: 9 PGY-1 residents underwent an established training curriculum for teaching the knowledge and technical skills involved in laparoscopic cholecystectomy. Initial training involved a didactic session, expert-led practice on a porcine model in a simulated operating room and laparoscopic skills practice on a virtual reality trainer. Residents then performed a laparoscopic cholecystectomy on the same porcine model as a preintervention test. Three to four months following this, residents were subjected to specific nontechnical skills training involving 2 simple team-based laparoscopic tasks. They then practiced a further 4 to 6 hours on the virtual reality trainer. A repeat postintervention laparoscopic cholecystectomy was then performed 3 to 4 months after nontechnical skills training. Both the preintervention and postintervention laparoscopic cholecystectomies were audiovisually recorded and then evaluated by 2 independent surgeons in a blinded fashion. Technical skills were assessed using objective structured assessment of technical skills (OSATS) and a technique specific rating scale (TRS) that we developed for laparoscopic cholecystectomy. Nontechnical skills were assessed using nontechnical skills for surgeons (NOTSS). Residents also completed a survey at the beginning and end of the training. SETTING: Tertiary care, university based teaching institution. PARTICIPANTS: A total of 9 general surgery residents at the intern level. RESULTS: The mean OSATS score improved from 13.7 ± 1.24 to 26.7 ± 0.31 (p < 0.001), the mean TRS score improved from 6 ± 0.46 to 13.1 ± 0.36 (p < 0.001) and the mean NOTSS score improved from 21.7 ± 1.83 to 36.3 ± 0.87 (p < 0.001) following the training. There was a strong correlation between OSATS and NOTSS scores (Pearson's R = 0.98) and TRS and NOTSS (R = 0.94). The inter-rater agreement was 0.79 for NOTSS, 0.9 for OSATS, and 0.82 for TRS. Following completion of the training, residents self-reported improvements in exchanging information (p < 0.01), coordinating activities (p < 0.01) and coping with pressure in the operating room (p < 0.001). CONCLUSION: Simple, team-based nontechnical skills training for laparoscopic cholecystectomy that was separate from technical skills training led to a sustained increase in residents' nontechnical skills 3 to 4 months after training. This was associated with a self-reported improvement in many nontechnical skills based on resident survey. Based on these results, we recommend that such designated nontechnical skills training is a valid alternative to other methods such as coaching and debriefing. We, therefore, plan to continue our efforts to develop team-based simulation tasks aimed at improving nontechnical skills for multiple surgical modalities.
