Racial and Ethnic Disparities in Operative Experience Among General Surgery Residents: A Multi-Institutional Study from the US ROPE Consortium.

OBJECTIVE: To determine the relationship between race/ethnicity and case volume among graduating surgical residents. BACKGROUND: Racial/ethnic minority individuals face barriers to entry and advancement in surgery; however, no large-scale investigations of the operative experience of racial/ethnic minority residents have been performed. METHODS: A multi-institutional retrospective analysis of the Accreditation Council for Graduate Medical Education case logs of categorical general surgery residents at 20 programs in the US Resident OPerative Experience Consortium database was performed. All residents graduating between 2010 and 2020 were included. The total, surgeon chief, surgeon junior, and teaching assistant case volumes were compared between racial/ethnic groups. RESULTS: The cohort included 1343 residents. There were 211 (15.7%) Asian, 65 (4.8%) Black, 73 (5.4%) Hispanic, 71 (5.3%) "Other" (Native American or Multiple Race), and 923 (68.7%) White residents. On adjusted analysis, Black residents performed 76 fewer total cases (95% CI, -109 to -43, P <0.001) and 69 fewer surgeon junior cases (-98 to -40, P <0.001) than White residents. Comparing adjusted total case volume by graduation year, both Black residents and White residents performed more cases over time; however, there was no difference in the rates of annual increase (10 versus 12 cases per year increase, respectively, P =0.769). Thus, differences in total case volume persisted over the study period. CONCLUSIONS: In this multi-institutional study, Black residents graduated with lower case volume than non-minority residents throughout the previous decade. Reduced operative learning opportunities may negatively impact professional advancement. Systemic interventions are needed to promote equitable operative experience and positive culture change.

Disparities in the Operative Experience Between Female and Male General Surgery Residents: A Multi-institutional Study From the US ROPE Consortium.

OBJECTIVE: To examine differences in resident operative experience between male and female general surgery residents. BACKGROUND: Despite increasing female representation in surgery, sex and gender disparities in residency experience continue to exist. The operative volume of male and female general surgery residents has not been compared on a multi-institutional level. METHODS: Demographic characteristics and case logs were obtained for categorical general surgery graduates between 2010 and 2020 from the US Resident OPerative Experience Consortium database. Univariable, multivariable, and linear regression analyses were performed to compare differences in operative experience between male and female residents. RESULTS: There were 1343 graduates from 20 Accreditation Council for Graduate Medical Education-accredited programs, and 476 (35%) were females. There were no differences in age, race/ethnicity, or proportion pursuing fellowship between groups. Female graduates were less likely to be high-volume residents (27% vs 36%, P < 0.01). On univariable analysis, female graduates performed fewer total cases than male graduates (1140 vs 1177, P < 0.01), largely due to a diminished surgeon junior experience (829 vs 863, P < 0.01). On adjusted multivariable analysis, female sex was negatively associated with being a high-volume resident (OR = 0.74, 95% CI: 0.56 to 0.98, P = 0.03). Over the 11-year study period, the annual total number of cases increased significantly for both groups, but female graduates (+16 cases/year) outpaced male graduates (+13 cases/year, P = 0.02). CONCLUSIONS: Female general surgery graduates performed significantly fewer cases than male graduates. Reassuringly, this gap in operative experience may be narrowing. Further interventions are warranted to promote equitable training opportunities that support and engage female residents.

A multi-institutional study from the US ROPE Consortium examining factors associated with directly entering practice upon residency graduation.

BACKGROUND: There is concern regarding the competency of today's general surgery graduates as a large proportion defer independent practice in favor of additional fellowship training. Little is known about the graduates who directly enter general surgery practice and if their operative experiences during residency differ from graduates who pursue fellowship. METHODS: Nineteen Accreditation Council for Graduate Medical Education-accredited general surgery programs from the US Resident OPerative Experience Consortium were included. Demographics, career choice, and case logs from graduates between 2010 to 2020 were analyzed. RESULTS: There were 1,264 general surgery residents who graduated over the 11-year period. A total of 248 (19.6%) went directly into practice and 1,016 (80.4%) pursued fellowship. Graduates directly entering practice were more likely to be a high-volume resident (43.1% vs 30.5%, P < .01) and graduate from a high-volume program (49.2% vs 33.0%, P < .01). Direct-to-practice graduates performed 53 more cases compared with fellowship-bound graduates (1,203 vs 1,150, P < .01). On multivariable analysis, entering directly into practice was positively associated with total surgeon chief case volume (odds ratio = 1.47, 95% confidence interval 1.18-1.84, P < .01) and graduating from a US medical school (odds ratio = 2.54, 95% confidence interval 1.45-4.44, P < .01) while negatively associated with completing a dedicated research experience (odds ratio = 0.31, 95% confidence interval 0.22-0.45, P < .01). CONCLUSION: This is the first multi-institutional study exploring resident operative experience and career choice. These data suggest residents who desire immediate practice can tailor their experience with less research time and increased operative volume. These data may be helpful for programs when designing their experience for residents with different career goals.

Rethinking Routine Intensive Care After Cytoreductive Surgery With Heated Intraperitoneal Chemotherapy: The Fiscal Argument.

BACKGROUND: Patients undergoing cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) are frequently admitted to the intensive care unit (ICU) for mitigation of potential complications, although ICU length of stay (LOS) is a significant driver of cost. This study asked whether a fiscal argument could be made for the selective avoidance of ICU admission after CRS/HIPEC. METHODS: Prospective data for select low-risk patients (e.g., lower peritoneal cancer index [PCI]) admitted to the intermediate care unit (IMC) instead of the ICU after CRS/HIPEC were matched with a historic cohort routinely admitted to the ICU. Cohort comparisons and the impact of the intervention on cost were assessed. RESULTS: The study matched 81 CRS/HIPEC procedures to form a cohort of 49 pre- and 15 post-intervention procedures for patients with similar disease burdens (mean PCI, 8 ± 6.7 vs. 7 ± 5.1). The pre-intervention patients stayed a median of 1 day longer in the ICU (1 day [IQR, 1-1 day] vs. 0 days [IQR, 0-0 days]) and had a longer LOS (8 days [IQR, 7-11 days] vs. 6 days [IQR, 5.5-9 days]). Complications and complication severity did not differ statistically. The median total hospital cost was lower after intervention ($30,845 [IQR, $30,181-$37,725] vs. $41,477 [IQR, $33,303-$51,838]), driven by decreased indirect fixed cost ($8984 [IQR, $8643-$11,286] vs. $14,314 [IQR, $12,206-$18,266]). In a weighted multiple variable linear regression analysis, the intervention was associated with a savings of $2208.68 per patient. CONCLUSIONS: Selective admission to the IMC after CRS/HIPEC was associated with $2208.68 in savings per patient without added risk. In this era of cost-conscious practice of medicine, these data highlight an opportunity to decrease cost by more than 5% for patients undergoing CRS/HIPEC.

Gender Differences in Entrustable Professional Activity Evaluations of General Surgery Residents.

OBJECTIVE: To determine differences in entrustable professional activity (EPA) assessments between male and female general surgery residents. SUMMARY BACKGROUND DATA: Evaluations play a critical role in career advancement for physicians. However, female physicians in training receive lower evaluations and underrate their own performance. Competency-based assessment frameworks, such as EPAs, may help address gender bias in surgery by linking evaluations to specific, observable behaviors. METHODS: In this cohort study, EPA assessments were collected from July 2018 to May 2020. The effect of resident sex on EPA entrustment levels was analyzed using multiple linear and ordered logistic regressions. Narrative comments were analyzed using latent dirichlet allocation to identify topics correlated with resident sex. RESULTS: Of the 2480 EPAs, 1230 EPAs were submitted by faculty and 1250 were submitted by residents. After controlling for confounding factors, faculty evaluations of residents were not impacted by resident sex (estimate = 0.09, P = 0.08). However, female residents rated themselves lower by 0.29 (on a 0-4 scale) compared to their male counterparts (P < 0.001). Within narrative assessments, topics associated with resident sex demonstrated that female residents focus on the "guidance" and "supervision" they received while performing an EPA, while male residents were more likely to report "independent" action. CONCLUSIONS: Faculty assessments showed no difference in EPA levels between male and female residents. Female residents rate themselves lower by nearly an entire post graduate year (PGY) level compared to male residents. Latent dirichlet allocation -identified topics suggest this difference in self-assessment is related to differences in perception of autonomy.

The Relative Impact of Specific Postoperative Complications on Older Patients Undergoing Hip Fracture Repair.

BACKGROUND: Hip fractures affect a vulnerable population and are associated with high rates of morbidity, mortality, and resource utilization. Although postoperative complications are a known driver of mortality and resource utilization, the comparative impacts of specific complications on outcomes is unknown. This study assessed which complications are associated with the highest effects on mortality and resource utilization for older patients who undergo hip fracture repair. METHODS: Patients ≥ 65 years of age who underwent hip fracture repair during 2016-2017 included in the Hip Fracture Targeted ACS NSQIP (American College of Surgeons National Surgical Quality Improvement Program) database populated the data set. Prolonged hospitalization (≥ 75th percentile) and 30-day mortality and readmission were the primary outcomes. Population attributable fractions (PAFs) were used to quantify the anticipated reduction in the primary outcomes that would result from complete prevention of 10 postoperative complications. RESULTS: Of 17,755 patients across 117 hospitals, 70.9% were female, 26.0% were over age 90, 22.8% had an American Society of Anesthesiologists (ASA) score of 4-5, and 53.9% presented with an intertrochanteric fracture. Postoperative delirium affected 29.8% of patients and was associated with death (PAF 18.0%; 95% confidence interval [CI] = 13.2-22.5), prolonged hospitalization (PAF 14.3%; 95% CI = 12.7-15.8), and readmission (PAF 15.0%; 95% CI = 11.3-18.6). Pneumonia affected 4.1% of patients and was associated with death (PAF 10.9%; 95% CI = 8.9-12.8), prolonged hospitalization (PAF 4.0%; 95% CI = 3.5-4.5), and readmission (PAF 9.1%; 95% CI = 7.5-10.7). The impact of the other eight complications was comparatively small. CONCLUSION: Postoperative delirium and pneumonia are the highest-impact complications for older hip fracture repair patients. These complications should be prioritized in quality improvement efforts that target this patient population.

Surgeon Variability Impacts Costs in Laparoscopic Cholecystectomy: the Volume-Cost Relationship.

BACKGROUND: Physician variation in adherence to best practices contributes to the high costs of health care. Understanding surgeon-specific cost variation in common surgical procedures may inform strategies to improve the value of surgical care. METHODS: Laparoscopic cholecystectomies at a single institution were identified over a 5-year period and linked to an institutional cost database. Multiple linear regression was used to control for patient-, case-, and hospital-specific factors while assessing the impact of surgeon variability on cost. RESULTS: The final dataset contained 1686 patients. Higher surgeon volume (reported in tertiles) was associated with decreased costs ($5354 vs. $6301 vs. $7156, p < 0.01) and OR times (66 min vs. 85 min vs. 95 min, p < 0.01). After controlling for patient-, case-, and hospital-specific factors, non-MIS fellowship training type (p < 0.01) and low surgeon volume (p < 0.01) were associated with increased costs, while time in practice did not contribute to cost variation (p = NS). CONCLUSIONS: Surgeon variability contributes to costs in laparoscopic cholecystectomy. Some of this variability is associated with operative volume and fellowship training. Collaboration to limit this cost variability may reduce surgical resource utilization.

Sentinel lymph node biopsy is associated with increased cost in higher risk thin melanoma.

INTRODUCTION: National Comprehensive Cancer Network guidelines recommend that sentinel lymph node biopsy (SLNB) be discussed with patients with thin melanoma at higher risk for lymph node metastasis (T1b or T1a with positive deep margins, lymphovascular invasion, or high mitotic index). We examined the association between SLNB and resource utilization in this cohort. METHODS: We conducted a retrospective cohort study of patients that underwent wide local excision for higher risk thin melanomas from 2009 to 2018 at a tertiary care center. Patients who underwent SLNB were compared to those who did not undergo SLNB with regard to resource utilization, including total hospital cost. RESULTS: A total of 70 patients were included in the analysis and 50 patients (71.4%) underwent SLNB. SLNB was associated with increased hospital costs ($6700 vs. $3767; p < .01) and increased operative time (68.5 vs. 36.0 min; p < .01). This cost difference persisted in multivariable regression (p < .01). Of patients who underwent successful SLN mapping, 3 out of 49 patients had a positive SLN (6.1%). The cost to identify a single positive sentinel lymph node (SLN) was $47,906. CONCLUSION: In patients with a higher risk of thin melanoma, SLNB is associated with increased cost despite a low likelihood of SLN positivity. These data better inform patient-provider discussions as the role of SLNB in thin melanoma evolves.

Natural language processing and entrustable professional activity text feedback in surgery: A machine learning model of resident autonomy.

BACKGROUND: Entrustable Professional Activities (EPAs) contain narrative 'entrustment roadmaps' designed to describe specific behaviors associated with different entrustment levels. However, these roadmaps were created using expert committee consensus, with little data available for guidance. Analysis of actual EPA assessment narrative comments using natural language processing may enhance our understanding of resident entrustment in actual practice. METHODS: All text comments associated with EPA microassessments at a single institution were combined. EPA-entrustment level pairs (e.g. Gallbladder Disease-Level 1) were identified as documents. Latent Dirichlet Allocation (LDA), a common machine learning algorithm, was used to identify latent topics in the documents associated with a single EPA. These topics were then reviewed for interpretability by human raters. RESULTS: Over 18 months, 1015 faculty EPA microassessments were collected from 64 faculty for 80 residents. LDA analysis identified topics that mapped 1:1 to EPA entrustment levels (Gammas >0.99). These LDA topics appeared to trend coherently with entrustment levels (words demonstrating high entrustment were consistently found in high entrustment topics, word demonstrating low entrustment were found in low entrustment topics). CONCLUSIONS: LDA is capable of identifying topics relevant to progressive surgical entrustment and autonomy in EPA comments. These topics provide insight into key behaviors that drive different level of resident autonomy and may allow for data-driven revision of EPA entrustment maps.

Renal Function After Retroperitoneal Sarcoma Resection with Nephrectomy: A Matched Analysis of the United States Sarcoma Collaborative Database.

BACKGROUND: Nephrectomy often is required during en bloc resection of a retroperitoneal sarcoma (RPS) to achieve an R0 or R1 resection. The impact of nephrectomy on postoperative renal function in this patient population, who also may benefit from subsequent nephrotoxic systemic therapy, is not well described. METHODS: The United States Sarcoma Collaborative (USSC) database was queried for patients undergoing RPS resection between 2000 and 2016. Patients with missing pre- or postoperative measures of renal function were excluded. A matched cohort was created using coarsened exact matching. Weighted logistic regression was used to control further for differences between the nephrectomy and non-nephrectomy cohorts. The primary outcomes were postoperative acute kidney injury (AKI), acute renal failure (ARF), and dialysis. RESULTS: The initial cohort consisted of 858 patients, 3 (0.3%) of whom required postoperative dialysis. The matched cohort consisted of 411 patients, 108 (26%) of whom underwent nephrectomy. The patients who underwent nephrectomy had higher rates of postoperative AKI (14.8% vs 4.3%; p < 0.01) and ARF (4.6% vs 1.3%; p = 0.04), but no patients required dialysis postoperatively. Logistic regression modeling showed that the risk of AKI (odds ratio [OR], 5.16; p < 0.01) and ARF (OR 5.04; p < 0.01) after nephrectomy persisted despite controlling for age and preoperative renal function. CONCLUSIONS: Nephrectomy is associated with an increased risk of postoperative AKI and ARF after RPS resection. This study was unable to statistically assess the impact of nephrectomy on postoperative dialysis, but the risk of postoperative dialysis is 0.5% or less regardless of nephrectomy status.

Intercostal nerve cryoablation is associated with lower hospital cost during minimally invasive Nuss procedure for pectus excavatum.

Minimally invasive repair of pectus excavatum (Nuss procedure) is associated with significant pain, and efforts to control pain impact resource utilization. Bilateral thoracic intercostal nerve cryoablation has been proposed as a novel technique to improve post-operative pain control, though the impact on hospital cost is unknown. METHODS: We conducted a retrospective study of patients undergoing a Nuss procedure from 2016 to 2019. Patients who received cryoablation were compared to those that received traditional pain control (patient-controlled analgesia or epidural). Outcome variables included postoperative opioid usage (milligram morphine equivalents, MME), length of stay (LOS), and hospital cost. RESULTS: Thirty-five of 73 patients studied (48%) received intercostal nerve cryoablation. LOS (1.0 vs 4.0 days, p < 0.01) and total hospital cost ($21,924 versus $23,694, p = 0.04) were decreased in the cryoablation cohort, despite longer operative time (152 vs 74 min, p < 0.01). Cryoablation was associated with decreased opioid usage (15.0 versus 148.6 MME, p < 0.01) during the 24 h following surgery and this persisted over the entire postoperative period, including discharge opioid prescription (112.5 vs 300.0 MME, p < 0.01). CONCLUSION: Bilateral intercostal nerve cryoablation is associated with decreased postoperative opioid usage and decreased resource utilization in pediatric patients undergoing a minimally invasive Nuss procedure for pectus excavatum. LEVEL OF EVIDENCE: Retrospective comparative study, level III.

Does Intentional Support of Degree Programs in General Surgery Residency Affect Research Productivity or Pursuit of Academic Surgery? A Multi-Institutional Study.

OBJECTIVE: To determine whether pursuit of an advanced degree during dedicated research time (DRT) in a general surgery residency training program impacts a resident's research productivity. DESIGN: A retrospective, multi-institutional cohort study. SETTING: General surgery residency programs that were approved to graduate more than 5 categorical residents per year and that offered at least 1 year of DRT were contacted for participation in the study. A total of 10 general surgery residency programs agreed to participate in the study. PARTICIPANTS: Residents who started their residency between 2000 and 2012 and spent at least one full year in DRT (n = 511) were included. Those who completed an advanced degree were compared on the following parameters to those who did not complete one: total number of papers, first-author papers, the Journal Citation Reports impact factors of publication (2018, or most recent), and first position after residency or fellowship training. RESULTS: During DRT, 87 (17%) residents obtained an advanced degree. The most common degree obtained was a Master of Public Health (MPH, n = 42 (48.8%)). Residents who did not obtain an advanced degree during DRT published fewer papers (median 8, [interquartile range 4-12]) than those who obtained a degree (9, [6-17]) (p = 0.002). They also published fewer first author papers (3, [2-6]) vs (5, [2-9]) (p = 0.002) than those who obtained a degree. Resident impact factor (RIF) was calculated using Journal Citation Reports impact factor and author position. Those who did not earn an advanced degree had a lower RIF (adjusted RIF, 84 ± 4 vs 134 ± 5, p < 0.001) compared to those who did. There was no association between obtaining a degree and pursuit of academic surgery (p = 0.13) CONCLUSIONS: Pursuit of an advanced degree during DRT is associated with increased research productivity but is not associated with pursuit of an academic career.

Retroperitoneal sarcoma perioperative risk stratification: A United States Sarcoma Collaborative evaluation of the ACS-NSQIP risk calculator.

BACKGROUND: The ACS-NSQIP risk calculator predicts perioperative risk. This study tested the calculator's ability to predict risk for outcomes following retroperitoneal sarcoma (RPS) resection. METHODS: The United States Sarcoma Collaborative database was queried for adults who underwent RPS resection. Estimated risk for outcomes was calculated twice in the risk calculator, once using sarcoma-specific CPT codes and once using codes indicative of most comorbid organ resection (eg nephrectomy). ROC curves were generated, with area under the curve (AUC) and Brier scores reported to assess discrimination and calibration. An AUC < 0.6 was considered ineffective discrimination. A negative ▲ Brier indicated improved performance relative to baseline outcome rates. RESULTS: In total, 482 patients were identified with a 42.3% 90-day complication rate. Discrimination was poor for all outcomes except "all complications" and "renal failure." Baseline outcome rates were better predictors than calculator estimates except for "discharge to nursing or rehab facility" and "renal failure." Replacing sarcoma-specific CPT codes with resection-specific codes did not improve performance. CONCLUSION: The ACS-NSQIP risk calculator poorly predicted outcomes following RPS resection. Changing sarcoma-specific CPT to resection-specific codes did not improve performance. Comorbidities in the calculator may not effectively capture perioperative risk. Future work should evaluate a sarcoma-specific calculator.

Entrustable Professional Activities in General Surgery: Trends in Resident Self-Assessment.

OBJECTIVE: Effective self-assessment is a cornerstone of lifelong professional development; however, evidence suggests physicians have a limited ability to self-assess. Novel strategies to improve the accuracy of learner self-assessment are needed. Our institution's surgical entrustable professional activity (EPA) implementation strategy incorporates resident self-assessment to address this issue. This study evaluates the accuracy of resident self-assessment versus faculty assessment across 5 EPAs in general surgery. DESIGN, SETTING, PARTICIPANTS: Within a single academic general surgery residency program, assessment data for 5 surgery EPAs was prospectively collected using a mobile application. Matched assessments (resident and faculty assessments for the same clinical encounter) were identified and the remainder excluded. Assessment scores were compared using Welch's t test. Agreement was analyzed using Cohen's kappa with squared weights. RESULTS: One thousand eight hundred and fifty-seven EPA assessments were collected in 17 months following implementation. One thousand one hundred and fifty-five (62.2%) were matched pairs. Residents under-rated their own performance relative to faculty assessments (2.36 vs 2.65, p < 0.01). This pattern held true for all subsets except for Postgraduate Year (PGY)2 residents and Inguinal Hernia EPAs. There was at least moderate agreement between matched resident and faculty EPA assessment scores (κ = 0.57). This was consistent for all EPAs except Trauma evaluations, which were completed by faculty from 2 different departments. Surgery resident self-assessments more strongly agreed with Surgery faculty assessments than Emergency Medicine faculty assessments (κ = 0.58 vs 0.36). CONCLUSIONS: Resident EPA self-assessments are equivalent or slightly lower than faculty assessments across a wide breadth of clinical scenarios. Resident and faculty matched assessments demonstrate moderate agreement.

What Drives High Costs of Cytoreductive Surgery and HIPEC: Patient, Provider or Tumor?

INTRODUCTION: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is utilized for peritoneal malignancies and is associated with significant resource use. To address potentially modifiable factors contributing to excessive cost, we sought to determine predictors of high cost of care for patients undergoing CRS/HIPEC. METHODS: An institutional CRS/HIPEC database was queried for adult patients from 2014 to 2018. Cost was defined as cost for the index hospitalization, and high-cost cases were defined as > 75th percentile for cost. Bivariate analyses for cost were performed, and all significant tumor, patient, and surgeon-specific variables were entered in a linear regression for cost. A separate linear regression was performed for length of stay (LOS). RESULTS: In total, 59 patients underwent 61 CRS/HIPEC procedures. The median direct variable cost was $20,509 (16,395-25,240). Median length of stay (LOS) was 8 (7-11.5) days and ICU stay was 1 (1-1.5) day. LOS, length of ICU stay and operative time were predictive of cost. Factors associated with increased LOS were Clavien-Dindo grade II complications and ostomy creation. Patient-related factors, including age and BMI, tumor-related factors, such as PCI and CCR, and surgeon were not predictive of cost nor LOS. DISCUSSION: Our results, the first to identify predictors of high cost of CRS/HIPEC-related care in the US, reveal cost was largely related to length and intensity of care. In turn, these drivers were influenced by complications and operative factors. Future work will focus on identifying an appropriate ERAS protocol following CRS/HIPEC and selection of those patients that may avoid routine ICU admission.

Operative Delay in Adults with Appendicitis: Time is Money.

BACKGROUND: Evidence suggests that operative delay of up to 24 h is not associated with adverse outcomes among patients undergoing emergent appendectomy. However, the fiscal implication of operative delay is not well described in adults. We sought to examine the effect of delayed appendectomy on clinical outcomes and hospital cost. METHODS: We conducted a retrospective cohort study of patients undergoing nonelective laparoscopic appendectomy from 2014 to 2018 at both a tertiary care center and an affiliated short-stay hospital. Using a unique data set constructed from merged electronic health record and patient-level hospital financial data, patients with delayed surgery, defined as >12 h from emergency department (ED) arrival to operation, were compared with patients who underwent surgery within 12 h. Patient-specific variables were analyzed for their association with resource utilization, and subsequent multivariable linear regression was performed for total hospital cost. RESULTS: 1372 patients underwent laparoscopic appendectomy during the study period. 938 patients (68.3%) underwent surgery within 12 h of ED arrival, and 434 patients (31.6%) underwent delayed surgery. Delayed cases had longer length of stay (44.6 ± 42.5 versus 34.5 ± 36.5 h, P < 0.01) and increased total hospital cost ($9326 ± 4691 versus $8440 ± 3404, P < 0.01). The cost difference persisted on multivariable analysis (P < 0.01). There were no significant differences between delayed cases and nondelayed cases for operative time, intraoperative findings, including rate of perforation, or postoperative complications. CONCLUSIONS: Although safe, delayed appendectomy is associated with an increased length of stay and increased total hospital costs compared with appendectomy within 12 h of reaching the ED.

Summary perioperative risk metrics within the electronic medical record predict patient-level cost variation in pancreaticoduodenectomy.

BACKGROUND: Automated data extraction from the electronic medical record is fast, scalable, and inexpensive compared with manual abstraction. However, concerns regarding data quality and control for underlying patient variation when performing retrospective analyses exist. This study assesses the ability of summary electronic medical record metrics to control for patient-level variation in cost outcomes in pancreaticoduodenectomy. METHODS: Patients that underwent pancreaticoduodenectomy from 2014 to 2018 at a single institution were identified within the electronic medical record and linked with the National Surgical Quality Improvement Program. Variables in both data sets were compared using interrater reliability. Logistic and linear regression modelling of complications and costs were performed using combinations of comorbidities/summary metrics. Models were compared using the adjusted R2 and Akaike information criterion. RESULTS: A total of 117 patients populated the final data set. A total of 31 (26.5%) patients experienced a complication identified by the National Surgical Quality Improvement Program. The median direct variable cost for the encounter was US$14,314. Agreement between variables present in the electronic medical record and the National Surgical Quality Improvement Program was excellent. Stepwise linear regression models of costs, using only electronic medical record-extractable variables, were non-inferior to those created with manually abstracted individual comorbidities (R2 = 0.67 vs 0.30, Akaike information criterion 2,095 vs 2,216). Model performance statistics were minimally impacted by the addition of comorbidities to models containing electronic medical record summary metrics (R2 = 0.67 vs 0.70, Akaike information criterion 2,095 vs 2,088). CONCLUSION: Summary electronic medical record perioperative risk metrics predict patient-level cost variation as effectively as individual comorbidities in the pancreaticoduodenectomy population. Automated electronic medical record data extraction can expand the patient population available for retrospective analysis without the associated increase in human and fiscal resources that manual data abstraction requires.

Blueprint for Restructuring a Department of Surgery in Concert With the Health Care System During a Pandemic: The University of Wisconsin Experience.

The current health care environment is complex. Systems often cross US state boundaries to provide care to patients with a wide variety of medical needs. The coronavirus disease 2019 pandemic is challenging health care systems across the globe. Systems face varying levels of complexity as they adapt to the new reality. This pandemic continues to escalate in hot spots nationally and internationally, and the worst strain on health care systems may be yet to come. The purpose of this article is to provide a road map developed from lessons learned from the experience in the Department of Surgery at the University of Wisconsin School of Medicine and Public Health and University of Wisconsin Health, based on past experience with incident command structures in military combat operations and Federal Emergency Management Agency responses. We will discuss administrative restructuring leveraging a team-of-teams approach, provide a framework for deploying the workforce needed to deliver all necessary urgent health care and critical care to patients in the system, and consider implications for the future.
