RESUMO

OBJECTIVE: To establish whether Accreditation Council for Graduate Medical Education Milestones predict future performance of general surgery trainees. SUMMARY BACKGROUND DATA: Milestones provide bi-annual assessments of trainee progress across six competencies. It is unknown whether the Milestones predict surgeon performance after the transition to independent practice. METHODS: We performed a retrospective cohort study of surgeons with complete Milestone assessments in the fourth and fifth clinical years who treated patients in acute care hospitals within Florida, New York, and Pennsylvania, 2015-2018. To account for the multiple ways in which the Milestone assessments might predict post-graduation outcomes, we included 120 Milestones features in our elastic net machine learning models. The primary outcome was risk-adjusted patient death or serious morbidity. RESULTS: 278 general surgeons were included in the study. Milestone assessments 6-months into the fourth clinical year displayed a normal score distribution while multicollinearity and low score discrimination at the final assessment period were detected. Individual Milestones features from the Patient Care, Professionalism, and Systems-based Practice domains were most predictive of patient-related outcomes. For example, surgeons with worse patient outcomes had significantly lower scores in Patient Care 3 when compared to surgeons with better patient outcomes (High DSM, yes: 2.86 vs. no: 3.04, P=0.011). CONCLUSIONS: The Milestones features that were most predictive of better patient outcomes related to intraoperative skills, ethical principles, and patient navigation and safety, measured 12-18 months prior to graduation. The development of a parsimonious set of evidence-based Milestones that better correlate with surgeon experience could enhance surgical education.

RESUMO

OBJECTIVE: Many emergency general surgery (EGS) conditions can be managed operatively or nonoperatively, with outcomes that vary by diagnosis. We hypothesized that operative management would lead to higher in-hospital costs but to cost savings over time. BACKGROUND: EGS conditions account for $28 billion in health care costs in the United States annually. Compared with scheduled surgery, patients who undergo emergency surgery are at increased risk of complications, readmissions, and death, with accompanying costs of care that are up to 50% higher than elective surgery. Our prior work demonstrated that operative management had variable impacts on clinical outcomes depending on the EGS condition. METHODS: This was a nationwide, retrospective study using fee-for-service Medicare claims data. We included patients 65.5 years of age or older with a principal diagnosis for an EGS condition 7/1/2015-6/30/2018. EGS conditions were categorized as: colorectal, general abdominal, hepatopancreaticobiliary (HPB), intestinal obstruction, and upper gastrointestinal. We used near-far matching with a preference-based instrumental variable to adjust for confounding and selection bias. Outcomes included Medicare payments for the index hospitalization and at 30, 90, and 180 days. RESULTS: Of 507,677 patients, 30.6% received an operation. For HPB conditions, costs for operative management were initially higher but became equivalent at 90 and 180 days. For all others, operative management was associated with higher inpatient costs, which persisted, though narrowed, over time. Out-of-pocket costs were nearly equivalent for operative and nonoperative management. CONCLUSIONS: Compared with nonoperative management, costs were higher or equivalent for operative management of EGS conditions through 180 days, which could impact decision-making for clinicians, patients, and health systems in situations where clinical outcomes are similar.

RESUMO

OBJECTIVE: To examine the role of hub-and-spoke systems as a factor in structural racism and discrimination. BACKGROUND: Health systems are often organized in a "hub-and-spoke" manner to centralize complex surgical care to 1 high-volume hospital. Although the surgical health care disparities are well described across health care systems, it is not known how they seem across a single system's hospitals. METHODS: Adult patients who underwent 1 of 10 general surgery operations in 12 geographically diverse states (2016-2018) were identified using the Healthcare Cost and Utilization Project's State Inpatient Databases. System status was assigned using the American Hospital Association dataset. Hub designation was assigned in 2 ways: (1) the hospital performing the most complex operations (general hub) or (2) the hospital performing the most of each specific operation (procedure-specific hub). Independent multivariable logistic regression was used to evaluate the risk-adjusted odds of treatment at hubs by race and ethnicity. RESULTS: We identified 122,236 patients across 133 hospitals in 43 systems. Most patients were White (73.4%), 14.2% were Black, and 12.4% Hispanic. A smaller proportion of Black and Hispanic patient underwent operations at general hubs compared with White patients (B: 59.6% H: 52.0% W: 62.0%, P <0.001). After adjustment, Black and Hispanic patients were less likely to receive care at hub hospitals relative to White patients for common and complex operations (general hub B: odds ratio: 0.88 CI, 0.85, 0.91 H: OR: 0.82 CI, 0.79, 0.85). CONCLUSIONS: When White, Black, and Hispanic patients seek care at hospital systems, Black and Hispanic patients are less likely to receive treatment at hub hospitals. Given the published advantages of high-volume care, this new finding may highlight an opportunity in the pursuit of health equity.

RESUMO

OBJECTIVE: To determine the effect of operative versus nonoperative management of emergency general surgery conditions on short-term and long-term outcomes. BACKGROUND: Many emergency general surgery conditions can be managed either operatively or nonoperatively, but high-quality evidence to guide management decisions is scarce. METHODS: We included 507,677 Medicare patients treated for an emergency general surgery condition between July 1, 2015, and June 30, 2018. Operative management was compared with nonoperative management using a preference-based instrumental variable analysis and near-far matching to minimize selection bias and unmeasured confounding. Outcomes were mortality, complications, and readmissions. RESULTS: For hepatopancreaticobiliary conditions, operative management was associated with lower risk of mortality at 30 days [-2.6% (95% confidence interval: -4.0, -1.3)], 90 days [-4.7% (-6.50, -2.8)], and 180 days [-6.4% (-8.5, -4.2)]. Among 56,582 intestinal obstruction patients, operative management was associated with a higher risk of inpatient mortality [2.8% (0.7, 4.9)] but no significant difference thereafter. For upper gastrointestinal conditions, operative management was associated with a 9.7% higher risk of in-hospital mortality (6.4, 13.1), which increased over time. There was a 6.9% higher risk of inpatient mortality (3.6, 10.2) with operative management for colorectal conditions, which increased over time. For general abdominal conditions, operative management was associated with 12.2% increased risk of inpatient mortality (8.7, 15.8). This effect was attenuated at 30 days [8.5% (3.8, 13.2)] and nonsignificant thereafter. CONCLUSIONS: The effect of operative emergency general surgery management varied across conditions and over time. For colorectal and upper gastrointestinal conditions, outcomes are superior with nonoperative management, whereas surgery is favored for patients with hepatopancreaticobiliary conditions. For obstructions and general abdominal conditions, results were equivalent overall. These findings may support patients, clinicians, and families making these challenging decisions.

RESUMO

OBJECTIVE: The aim of this study was to investigate the association between a change in household support during the Covid-19 pandemic and surgeon stress. BACKGROUND: The hours and unpredictability of surgical practice often necessitate the employment of household extenders (eg, child caregivers) to maintain a safe home environment for surgeons and their families. The Covid-19 pandemic destabilized these relationships and provided an opportunity to reflect on the role that household extenders play in a surgical household. METHODS: A multi-institutional telephone survey of surgeons practicing at five geographically diverse academic institutions was conducted (May 15, 2020-June 5, 2020). Surgeons were classified by change in household extenders (HE) during the pandemic (decrease, increase, no change, or none). The primary outcome was self-reported surgeon stress level. Multivariable linear regression was used to examine the relationship between change in HE and surgeon stress, adjusting for training and relationship status, the presence of pets and children in the household, and study site. RESULTS: The majority (182, 54.3%) of surgeons employed HE before the pandemic; 121 (36.1%) reported a decrease in HE during the pandemic, 9 (2.7%) reported an increase, and 52 (15.5%) reported no change. Stress scores varied significantly by change in HE group ( P = 0.016). After controlling for potential confounders, having an increase in HE was associated with a higher stress score (+1.55 points) than having no decrease in HE (P = 0.033), and having a decrease in HE was associated with a higher stress score (+0.96 points) than having no decrease ( P = 0.004). CONCLUSIONS: Household extenders play a vital and complex role in enabling the healthcare workforce to care of the population. Surgeons who experienced a change in household extenders reported the highest stress levels. We suggest that health systems should proactively support surgeons by supporting the household extender workforce.

RESUMO

OBJECTIVE: We sought to compare postoperative outcomes of female surgeons (FS) and male surgeons (MS) within general surgery. SUMMARY OF BACKGROUND DATA: FS in the workforce are increasing in number. Female physicians provide exceptional care in other specialties. Differences in surgical outcomes of FS and MS have not been examined. METHODS: We linked the AMA Physician Masterfile to discharge claims from New York, Florida, and Pennsylvania (2012 to 2013) to examine practice patterns and to compare surgical outcomes of FS and MS. We paired FS and MS operating at the same hospital using cardinality matching with refined balance and compared inpatient mortality, any postoperative complication, and prolonged length of stay (pLOS) in FS and MS. RESULTS: Overall practice patterns differed between the 663 FS and 3219 MS. We identified 2462 surgeons (19% FS, 81% MS) at 429 hospitals who met inclusion criteria for outcomes analysis. FS were younger (mean age ±â€ŠSD FS: 48.5 ±â€Š8.4 years, MS: 54.3 ±â€Š9.4y; P < 0.001) with less clinical experience (mean years ±â€ŠSD FS: 11.6 ±â€Š8.3 y, MS: 17.6 ±â€Š10.0 years; P < 0.001) than MS before matching. FS had lower rates of inpatient mortality (FS: 1.51%, MS: 2.30%; P < 0.001), any postoperative complication (FS: 12.6%, MS: 16.1%; P < 0.001), and pLOS (FS: 18.4%, MS: 20.7%; P < 0.001) before matching. After matching, FS and MS outcomes were equivalent. CONCLUSION: Surgeon practice patterns vary by sex and experience. FS and MS with similar characteristics who treat similar patients at the same hospital have equivalent rates of inpatient morality, postoperative complications, and prolonged length of hospital stay. Patients should select the surgeon who is the best fit for them regardless of sex.
