Association of Hospital System Affiliation with Spending and Postoperative Outcomes: A Longitudinal Study of Hospital Mergers And Acquisitions From 2010 To 2018.

OBJECTIVE: To determine whether hospital system affiliation was associated with changes in surgical episode spending or postoperative outcomes. BACKGROUND: Over 70% of US hospitals are now part of a hospital system. The presumed benefits of hospital consolidation include concentrating volume and expertise, care integration, and investment in quality improvement. However, there is conflicting evidence as to whether expanding hospital systems are actually reducing health spending or improving quality. These observations call into question whether systems are leveraging their collective volume and experience to standardize care and maximize efficiencies. METHODS: The American Hospital Association Annual Survey was used to identify whether a hospital was part of a system and in which year a hospital joined the respective system. Using 100% Medicare claims data, we identified fee-for-service Medicare patients undergoing elective inpatient coronary artery bypass graft colon resection, lung resection, hip replacement, or knee replacement from 2010 to 2018. We used a difference-in-differences framework to evaluate hospital spending and outcomes before and after joining a system. The primary outcome was Medicare 30-day episode spending, with specific attention to the total episode payment, index hospitalization, and post-acute care components. Secondary outcomes included serious complications, 30-day mortality, and 30-day readmission. RESULTS: The cohort included 3,395,565 Medicare beneficiaries who underwent surgery between 2010 and 2018. Patients were treated at 3961 hospitals, of which 1097 (27.7%) were never in a system, 2262 (57.1%) were always in a system, and 602 (15.2%) joined a system during the study period. By 1 year after system affiliation, 30-day episode spending had decreased by $303 (95% CI: 63, 454, P=0.01), and after 5 years, 30-day episode spending decreased by $429 (95% CI: 5, 853, P=0.04). One year after system association, index hospitalization spending was not statistically different from before system affiliation ($-30, 95% CI: -160, 100, P=0.65). Conversely, 1 year after system association, postacute care spending decreased by $268 (95% CI: 107, 429, P<0.01) and remained lower for ≥5 years. There was no significant change in hospitals serious complications (-0.14, 95% CI: -0.40, 0.11, P=0.27), 30-day readmission (-0.14, 95% CI:-0.52, 0.25, P=0.48), or 30-day mortality (-0.08, 95% CI: -0.18, 0.03, P=0.17), 1 year after joining a system; similar patterns were observed at three and ≥5 years. CONCLUSIONS: system affiliation was associated with a small decrease in 30-day episode spending, driven by decreased spending in postacute care services. Notably, there was no difference in postoperative outcomes after system affiliation.

Private Equity Investment in Surgical Care.

OBJECTIVE: To characterize the extent of private equity investment affecting surgical care. SUMMARY BACKGROUND DATA: Over the last decade, investor-backed, for-profit private equity groups have invested in healthcare at an unprecedented rate, but the breadth of these investments affecting surgical practice remains largely unknown. METHODS: Four nationally representative databases were used to identify all merger/acquisitions involving surgical practices between 2015-2019, determine private equity investment in those transactions, and link the acquisitions with a physician dataset. RESULTS: 1,542 unique transactions were identified, of which 539 were financed by private equity. 58 transactions were then classified into their respective categories within surgical care: digestive disease, orthopedics, urology, vascular surgery, and plastic/cosmetic surgery. These transactions accounted for 199 practice sites and 1,405 physicians, averaging 24.2 physicians per transaction. Acquisition activity peaked in 2017 with a total of 63 practices involved. Digestive disease, urology, and orthopedic surgery accounted for the most activity. General surgeons were involved in a small share of the digestive disease practice acquisitions. Three "surgery-adjacent" categories were also identified: anesthesiology, ambulatory surgery centers, and surgical staffing firms. Among these, anesthesia was the largest category in terms of practices (194) and physicians (2,660) involved in transactions across the study period. Medical Service Organizations (MSOs) were a key mechanism through which private equity firms invested in surgical care. CONCLUSIONS: Private equity has engaged in substantial investment within surgical specialties, creating increased practice consolidation. These investments affect all levels of medical care and have notable implications for patients, practitioners, and policymakers.

Mortality and Severe Complications Among Newly Graduated Surgeons in the United States.

OBJECTIVE: To evaluate severe complications and mortality over years of independent practice among general surgeons. BACKGROUND: Despite concerns that newly graduated general surgeons may be unprepared for independent practice, it is unclear whether patient outcomes differ between early and later career surgeons. METHODS: We used Medicare claims for patients discharged between July 1, 2007 and December 31, 2019 to evaluate 30-day severe complications and mortality for 26 operations defined as core procedures by the American Board of Surgery. Generalized additive mixed models were used to assess the association between surgeon years in practice and 30-day outcomes while adjusting for differences in patient, hospital, and surgeon characteristics. RESULTS: The cohort included 1,329,358 operations performed by 14,399 surgeons. In generalized mixed models, the relative risk (RR) of mortality was higher among surgeons in their first year of practice compared with surgeons in their 15th year of practice [5.5% (95% CI: 4.1%-7.3%) vs 4.7% (95% CI: 3.5%-6.3%), RR: 1.17 (95% CI: 1.11-1.22)]. Similarly, the RR of severe complications was higher among surgeons in their first year of practice compared with surgeons in their 15th year of practice [7.5% (95% CI: 6.6%-8.5%) versus 6.9% (95% CI: 6.1%-7.9%), RR: 1.08 (95% CI: 1.03-1.14)]. When stratified by individual operation, 21 operations had a significantly higher RR of mortality and all 26 operations had a significantly higher RR of severe complications in the first compared with the 15th year of practice. CONCLUSIONS: Among general surgeons performing common operations, rates of mortality and severe complications were higher among newly graduated surgeons compared with later career surgeons.

Earned outcomes correlate with reliability-adjusted surgical mortality after abdominal aortic aneurysm repair and predict future performance.

OBJECTIVE: Cumulative, probability-based metrics are regularly used to measure quality in professional sports, but these methods have not been applied to health care delivery. These techniques have the potential to be particularly useful in describing surgical quality, where case volume is variable and outcomes tend to be dominated by statistical "noise." The established statistical technique used to adjust for differences in case volume is reliability-adjustment, which emphasizes statistical "signal" but has several limitations. We sought to validate a novel measure of surgical quality based on earned outcomes methods (deaths above average [DAA]) against reliability-adjusted mortality rates, using abdominal aortic aneurysm (AAA) repair outcomes to illustrate the measure's performance. METHODS: Earned outcomes methods were used to calculate the outcome of interest for each patient: DAA. Hospital-level DAA was calculated for non-ruptured open AAA repair and endovascular aortic repair (EVAR) in the Vascular Quality Initiative database from 2016 to 2019. DAA for each center is the sum of observed - predicted risk of death for each patient; predicted risk of death was calculated using established multivariable logistic regression modeling. Correlations of DAA with reliability-adjusted mortality rates and procedure volume were determined. Because an accurate quality metric should correlate with future results, outcomes from 2016 to 2017 were used to categorize hospital quality based on: (1) risk-adjusted mortality; (2) risk- and reliability-adjusted mortality; and (3) DAA. The best performing quality metric was determined by comparing the ability of these categories to predict 2018 to 2019 risk-adjusted outcomes. RESULTS: During the study period, 3734 patients underwent open repair (106 hospitals), and 20,680 patients underwent EVAR (183 hospitals). DAA was closely correlated with reliability-adjusted mortality rates for open repair (r = 0.94; P < .001) and EVAR (r = 0.99; P < .001). DAA also correlated with hospital case volume for open repair (r = -.54; P < .001), but not EVAR (r = 0.07; P = .3). In 2016 to 2017, most hospitals had 0% mortality (55% open repair, 57% EVAR), making it impossible to evaluate these hospitals using traditional risk-adjusted mortality rates alone. Further, zero mortality hospitals in 2016 to 2017 did not demonstrate improved outcomes in 2018 to 2019 for open repair (3.8% vs 4.6%; P = .5) or EVAR (0.8% vs 1.0%; P = .2) compared with all other hospitals. In contrast to traditional risk-adjustment, 2016 to 2017 DAA evenly divided centers into quality quartiles that predicted 2018 to 2019 performance with increased mortality rate associated with each decrement in quality quartile (Q1, 3.2%; Q2, 4.0%; Q3, 5.1%; Q4, 6.0%). There was a significantly higher risk of mortality at worst quartile open repair hospitals compared with best quartile hospitals (odds ratio, 2.01; 95% confidence interval, 1.07-3.76; P = .03). Using 2016 to 2019 DAA to define quality, highest quality quartile open repair hospitals had lower median DAA compared with lowest quality quartile hospitals (-1.18 DAA vs +1.32 DAA; P < .001), correlating with lower median reliability-adjusted mortality rates (3.6% vs 5.1%; P < .001). CONCLUSIONS: Adjustment for differences in hospital volume is essential when measuring hospital-level outcomes. Earned outcomes accurately categorize hospital quality and correlate with reliability-adjustment but are easier to calculate and interpret. From 2016 to 2019, highest quality open AAA repair hospitals prevented >40 perioperative deaths compared with the average hospital, and >80 perioperative deaths compared with lowest quality hospitals.

Variability in surgical approaches to hernias in patients with ascites.

BACKGROUND: Hernias in patients with ascites are common, however we know very little about the surgical repair of hernias within this population. The study of these repairs has largely remained limited to single center and case studies, lacking a population-based study on the topic. STUDY DESIGN: The Michigan Surgical Quality Collaborative and its corresponding Core Optimization Hernia Registry (MSQC-COHR) which captures specific patient, hernia, and operative characteristics at a population level within the state was used to conduct a retrospective review of patients with ascites undergoing ventral or inguinal hernia repair between January 1, 2020 and May 3, 2022. The primary outcome observed was incidence and surgical approach for both ventral and inguinal hernia cohorts. Secondary outcomes included 30-day adverse clinical outcomes as listed here: (ED visits, readmission, reoperation and complications) and surgical priority (urgent/emergent vs elective). RESULTS: In a cohort of 176 patients with ascites, surgical repair of hernias in patients with ascites is a rare event (1.4% in ventral hernia cohort, 0.2% in inguinal hernia cohort). The post-operative 30-day adverse clinical outcomes in both cohorts were greatly increased compared to those without ascites (ventral: 32% inguinal: 30%). Readmission was the most common complication in both inguinal (n = 14, 15.9%) and ventral hernia (n = 17, 19.3%) groups. Although open repair was most common for both cohorts (ventral: 86%, open: 77%), minimally invasive (MIS) approaches were utilized. Ventral hernias presented most commonly urgently/emergently (60%), and in contrast many inguinal hernias presented electively (72%). CONCLUSION: A population-level, ventral and incisional hernia database capturing operative details for 176 patients with ascites. There was variation in the surgical approaches performed for this rare event and opportunities for optimization in patient selection and timing of repair.

Use of statewide financial incentives to improve documentation of hernia and mesh characteristics in ventral hernia repair.

BACKGROUND: Documentation of intraoperative details is critical for understanding and advancing hernia care, but is inconsistent in practice. Therefore, to improve data capture on a statewide level, we implemented a financial incentive targeting documentation of hernia defect size and mesh use. METHODS: The Abdominal Hernia Care Pathway (AHCP), a voluntary pay for performance (P4P) initiative, was introduced in 2021 within the statewide Michigan Surgical Quality Collaborative (MSQC). This consisted of an organizational-level financial incentive for achieving 80% performance on eight specific process measures for ventral hernia surgery, including complete documentation of hernia defect size and location, as well as mesh characteristics and fixation technique. Comparisons were made between AHCP and non-AHCP sites in 2021. RESULTS: Of 69 eligible sites, 47 participated in the AHCP in 2021. There were N = 5362 operations (4169 at AHCP sites; 1193 at non-AHCP sites). At AHCP sites, 69.8% of operations had complete hernia documentation, compared to 50.5% at non-AHCP sites (p < 0.0001). At AHCP sites, 91.4% of operations had complete mesh documentation, compared to 86.5% at non-AHCP sites (p < 0.0001). The site-level hernia documentation goal of 80% was reached by 14 of 47 sites (range 14-100%). The mesh documentation goal was reached by 41 of 47 sites (range 4-100%). CONCLUSIONS: Addition of an organizational-level financial incentive produced marked gains in documentation of intra-operative details across a statewide surgical collaborative. The relatively large effect size-19.3% for hernia-is remarkable among P4P initiatives. This result may have been facilitated by surgeons' direct role in documenting hernia size and mesh use. These improvements in data capture will foster understanding of current hernia practices on a large scale and may serve as a model for improvement in collaboratives nationally.

Association of Neighborhood Deprivation, Race, and Postoperative Outcomes: Improvement in Neighborhood Deprivation is Associated With Worsening Surgical Disparities.

INTRODUCTION: While there is a broad understanding that patient factors, hospital characteristics, and an individual's neighborhoods all contribute to the observed disparities, the relationship between these factors remains unclear. The purpose of this study was to evaluate the association of neighborhood deprivation improve postoperative outcomes for White and Black Medicare beneficiaries equally. METHODS: We performed a cross-sectional Retrospective cohort study from 2014 to 2018 of 1372,487 White and Black Medicare beneficiaries aged 65 and older who underwent an inpatient colon resection, coronary artery bypass, cholecystectomy, appendectomy, or incisional hernia repair. We compared postoperative complications, readmission, and mortality by race across neighborhood deprivation. Outcomes were risk-adjusted using a multivariable logistical regression model accounting for patient factors (age, sex, Elixhauser comorbidities), admission type (elective, urgent, emergency), type of operation, and each neighborhoods Area Deprivation Index; a modern-day measure of neighborhood disadvantage that includes education, employment, housing quality, and poverty measures. RESULTS: Overall, 1372,487 Medicare beneficiaries with mean age 72.1 years, 50.3% female, 91.2% White, residing in 1107,051 unique neighborhoods underwent 1 of 5 operations. The proportion of Black beneficiaries was 6.5% within the lowest deprivation neighborhoods and increased to 16.9% within the highest deprivation neighborhoods ( P <0.001). The interaction between beneficiary neighborhood and race demonstrated that the association of neighborhood on outcomes varied by race. Specifically, White beneficiaries had 1.5% absolute mortality decrease from the highest to lowest deprivation neighborhoods [odds ratio (OR):1.32, 95% confidence interval (CI): 1.27-1.38; P <0.001], whereas Black beneficiaries had a 0.72% absolute mortality decrease from the highest to lowest deprivation neighborhoods (OR: 1.13, 95% CI: 1.02-1.24; P =0.018). Similarly, White beneficiaries had 3.6% absolute decrease in complication rate from the highest to lowest deprivation neighborhoods (OR: 1.23, 95% CI: 1.21-1.28; P <0.001) while Black beneficiaries had a 1.2%% absolute decrease in complication rate from the highest to lowest deprivation neighborhoods (OR: 1.07, 95% CI: 1.01-1.13; P =0.017). For 30-day readmission rates, White beneficiaries realized a 2.3% absolute decrease from the highest to lowest deprivation neighborhoods (OR: 1.19, 95% CI: 1.02-1.24; P <0.001), whereas Black beneficiaries saw no change (OR: 1.03, 95% CI: 0.97-1.10; P =0.269). CONCLUSIONS AND RELEVANCE: Lower neighborhood deprivation is associated with improved outcomes across both White and Black Medicare beneficiaries; however, improvement in neighborhood deprivation disproportionately favored White beneficiaries. These findings provide a cautionary example of the misperception of the protective effect of higher social class for Black patients and provide a cautionary example that improvements in neighborhoods may have disparate health impact on its members.

Neighborhood Deprivation, Hospital Quality, and Mortality After Cancer Surgery.

OBJECTIVE: To evaluate if receipt of complex cancer surgery at high-quality hospitals is associated with a reduction in disparities between individuals living in the most and least deprived neighborhoods. BACKGROUND: The association between social risk factors and worse surgical outcomes for patients undergoing high-risk cancer operations is well documented. To what extent neighborhood socioeconomic deprivation as an isolated social risk factor known to be associated with worse outcomes can be mitigated by hospital quality is less known. METHODS: Using 100% Medicare fee-for-service claims, we analyzed data on 212,962 Medicare beneficiaries more than age 65 undergoing liver resection, rectal resection, lung resection, esophagectomy, and pancreaticoduodenectomy for cancer between 2014 and 2018. Clinical risk-adjusted 30-day postoperative mortality rates were used to stratify hospitals into quintiles of quality. Beneficiaries were stratified into quintiles based on census tract Area Deprivation Index. The association of hospital quality and neighborhood deprivation with 30-day mortality was assessed using logistic regression. RESULTS: There were 212,962 patients in the cohort including 109,419 (51.4%) men with a mean (SD) age of 73.8 (5.9) years old. At low-quality hospitals, patients living in the most deprived areas had significantly higher risk-adjusted mortality than those from the least deprived areas for all procedures; esophagectomy: 22.3% versus 20.7%; P <0.003, liver resection 19.3% versus 16.4%; P <0.001, pancreatic resection 15.9% versus 12.9%; P <0.001, lung resection 8.3% versus 7.8%; P <0.001, rectal resection 8.8% versus 8.1%; P <0.001. Surgery at a high-quality hospitals was associated with no significant differences in mortality between individuals living in the most compared with least deprived neighborhoods for esophagectomy, rectal resection, liver resection, and pancreatectomy. For example, the adjusted odds of mortality between individuals living in the most deprived compared with least deprived neighborhoods following esophagectomy at low-quality hospitals (odds ratio=1.22, 95% CI: 1.14-1.31, P <0.001) was higher than at high-quality hospitals (odds ratio=0.98, 95% CI: 0.94-1.02, P =0.03). CONCLUSION AND RELEVANCE: Receipt of complex cancer surgery at a high-quality hospital was associated with no significant differences in mortality between individuals living in the most deprived neighborhoods compared with least deprived. Initiatives to increase access referrals to high-quality hospitals for patients from high deprivation levels may improve outcomes and contribute to mitigating disparities.

Bundled Payments for Care Improvement Efficacy Across 3 Common Operations.

OBJECTIVE: The aim of this study was to evaluate associations between hospital participation in Bundled Payments for Care Improvement (BPCI) and 30-day total episode and post-acute care spending for lower extremity joint replacement (LEJR), coronary artery bypass graft (CABG), and colec-tomy. SUMMARY BACKGROUND DATA: BPCI has been shown to reduce spending for LEJR episodes largely from reductions in post-acute care. However, BPCI efficacy in other common elective procedures, including CABG and colec-tomy, remains unclear. It is also unknown whether post-acute care spending reductions drive total spending reductions outside of LEJR. METHODS: Retrospective cohort study using 100% Medicare claims data to identify BPCI (312 total) and non-BPCI (1,977 total) acute care hospitals from January 1, 2010 to November 30, 2016 with Medicare-enrolled patient discharges for at least one of the following BPCI episodes: LEJR (454,369 episodes), CABG (107,307 episodes), or colectomy (73,717 episodes). Along with difference-in-differences (DiD) analysis, we constructed generalized synthetic controls in the presence of nonparallel trends to estimate associations between BPCI participation and 30-day total and post-acute care spending. RESULTS: DiD estimates indicated reduced spending for LEJR (-$541.6 [95% confidence interval (CI): -718.0 to -365.3]) and colectomy (-$582.1 [95% CI: -927.3 to -236.8]) but not CABG (-$268.9 [95% CI: -831.5 to 293.7]). Generalized synthetic control estimates indicated reduced spending for LEJR (-$795.3 [95% CI: -10,22.1 to -582.2]) but not colectomy (-$251.3 [95% CI: -997.9 to 335.2]) or CABG (-$257.8 [95% CI: -10,24.6 to 414.8]).Post-acute care comprised 42.6% of LEJR spending reductions and 53.0% of colectomy spending reductions. CONCLUSIONS: BPCI participation was associated with significant spending reductions for LEJR and colectomy but not CABG. We conclude that BPCI has episode-dependent efficacy, largely determined by post-acute care.

Association of Health Professional Shortage Area Hospital Designation With Surgical Outcomes and Expenditures Among Medicare Beneficiaries.

OBJECTIVE: To compare surgical outcomes and expenditures at hospitals located in Health Professional Shortage Areas to nonshortage area designated hospitals among Medicare beneficiaries. BACKGROUND: More than a quarter of Americans live in federally designated Health Professional Shortage Areas. Although there is growing concern that medical outcomes may be worse, far less is known about hospitals providing surgical care in these areas. METHODS: Cross-sectional retrospective study from 2014 to 2018 of 842,787 Medicare beneficiary patient admissions to hospitals with and without Health Professional Shortage Area designations for common operations including appendectomy, cholecystectomy, colectomy, and hernia repair. We assessed risk-adjusted outcomes using multivariable logistic regression accounting for patient factors, admission type, and year were compared for each of the 4 operations. Hospital expenditures were price-standardized, risk-adjusted 30-day surgical episode payments. Primary outcome measures included 30-day mortality, hospital readmissions, and 30-day surgical episode payments. RESULTS: Patients (mean age=75.6 years, males=44.4%) undergoing common surgical procedures in shortage area hospitals were less likely to be White (84.6% vs 88.4%, P <0.001) and less likely to have≥2 Elixhauser comorbidities (75.5% vs 78.2%, P <0.001). Patients undergoing surgery at Health Professional Shortage Area hospitals had lower risk-adjusted rates of 30-day mortality (6.05% vs 6.69%, odds ratio=0.90, CI, 0.90-0.91, P <0.001) and readmission (14.99% vs 15.74%, odds ratio=0.94, CI, 0.94-0.95, P <0.001). Medicare expenditures at Health Professional Shortage Area hospitals were also lower than nonshortage designated hospitals ($28,517 vs $29,685, difference= -$1168, P <0.001). CONCLUSIONS: Patients presenting to Health Professional Shortage Area hospitals obtain safe care for common surgical procedures without evidence of higher expenditures among Medicare beneficiaries. These findings should be taken into account as current legislative proposals to increase funding for care in these underserved communities are considered.

Surgical Procedures at Critical Access Hospitals Within Hospital Networks.

OBJECTIVE: To compare surgical outcomes and expenditures at critical access hospitals that do versus do not participate in a hospital network among Medicare beneficiaries. BACKGROUND: Critical access hospitals provide essential care to more than 80 million Americans. These hospitals, often rural, are located more than 35 miles away from another hospital and are required to maintain patient transfer agreements with other facilities capable of providing higher levels of care. Some critical access hospitals have gone further to formally participate in a hospital network. METHODS: This was a cross-sectional retrospective study from 2014 to 2018 comparing 16,128 Medicare beneficiary admissions for appendectomy, cholecystectomy, colectomy, or hernia repair at critical access hospitals that do versus do not participate in a hospital network. Thirty-day mortality and readmissions were risk adjusted using multivariable logistic regression accounting for patient and hospital factors. Price-standardized, risk-adjusted Medicare expenditures were compared for the 30-day total episode payments consisting of index hospitalization, physician services, readmissions, and postacute care payments. RESULTS: Beneficiaries (average age = 75.7 years, SD = 7.4) who obtained care at critical access hospitals in a hospital network were more likely to carry ≥2 Elixhauser comorbidities (68.7% vs. 62.8%, P < 0.001). Rates of 30-day mortality were higher at critical access hospitals in a hospital network (4.30% vs. 3.81%, OR = 1.11, P < 0.001). Similarly, readmission rates were higher at critical access hospitals that were in a hospital network (15.13% vs. 14.34%, OR = 1.06, P < 0.001). Additionally, total episode payments were found to be $960 higher per patient at critical access hospitals that were in a hospital network ($23,878 vs. $22,918, P < 0.001). CONCLUSIONS: Critical access hospitals within hospital networks provided care to more medically complex patients and were associated with worse clinical outcomes and higher costs among Medicare beneficiaries undergoing common general surgery operations.

"I Came up Short on the Academic Ladder": A Grounded Theory Study of Careerism in Academic Surgery.

OBJECTIVE: This study aims to explore the definition of career success in academic surgery. BACKGROUND: Career success in academic surgery is frequently defined as the achievement of a specific title, from full professor to department chair. This type of definition is convenient and established but potentially incomplete. The business literature has a more nuanced view of the relationship between titles and success, but this relationship has not been studied in medicine. METHODS: Semi-structured interviews were conducted from May to November 2020. Data were analyzed in an iterative fashion using grounded theory methodology to develop a conceptual model. RESULTS: We conducted 26 semi-structured interviews with practicing surgeons differing in years of experience; 12 (46%) participants were female, mean age of 48. Participants included 5 chairs of surgery, 6 division chiefs, and 7 past or current presidents of national societies. Four themes emerged on the importance of titles: Some study participants reported that (1) titles are a barometer of success; others argued that (2) titles are not a sufficient metric to define success; (3) titles are a means to an end; and (4) there is a desire to achieve the title of a respected mentor. CONCLUSIONS: As the definition of career success in academic surgery changes to encompass a broader range of interests and ambitions, the traditional markers of success must come into review. Academic surgeons see the value of titles as a marker of success and as a means to achieving other goals, but overwhelmingly our interviewees felt that titles were a double-edged sword and that a more inclusive definition of academic success was needed.

Coronary Artery Bypass Surgery Among Medicare Beneficiaries in Health Professional Shortage Areas.

OBJECTIVE: Health professional shortage areas (HPSAs) were created by the Health Resources and Services Administration to identify communities with a shortage of clinical providers. For medical conditions, these designations are associated with worse outcomes. However, far less is known about patients undergoing high-complexity surgical procedures, such as coronary artery bypass grafting (CABG). BACKGROUND: The aim was to compare postoperative surgical outcomes of high-complexity surgery in beneficiaries living in HPSA versus non-HPSA designated areas. METHODS: This study is a retrospective cohort review of Medicare beneficiaries who underwent CABG between 2014 and 2018. The authors compared risk-adjusted 30-day mortality, complication, reoperation, and readmission rates for beneficiaries living in a designated HPSA versus non-HPSA using a multivariable logistic regression model accounting for patient (eg, age, sex, comorbidities, surgery year) and hospital characteristics (eg, patient-to-nurse ratio, teaching status). Patient travel burden was measured based on the time and distance required to travel from the beneficiary's home zip code to the hospital zip code. RESULTS: Of the 370,532 Medicare beneficiaries who underwent CABG, 30,881 (8.3%) lived in a HPSA. Beneficiaries in HPSAs were found to experience comparable 30-day mortality (3.50% vs. 3.65%, P <0.001), complication (32.67% vs. 33.54%, P <0.001), reoperation (1.58% vs. 1.66%, P <0.001), and readmission (14.72% vs. 14.86%, P <0.001) rates. Beneficiaries experienced greater mean travel times (91.2 vs. 64.0 minutes, P <0.001) and mean travel distances (85.0 vs. 59.3 miles, P <0.001). CONCLUSIONS: Medicare beneficiaries living in designated HPSA experienced comparable surgical outcomes after CABG surgery but a significantly greater travel burden. The greater travel burden experienced by patients living in designated shortage areas to obtain comparable surgical care for complex procedures demonstrates important tradeoffs between access and quality.

Comparative Outcomes of Groin Hernia Repair by Sex Among Medicare Beneficiaries.

OBJECTIVE: To compare the rates of operative recurrence between male and female patients undergoing groin hernia repair. BACKGROUND DATA: Groin hernia repair is common but understudied in females. Limited prior work demonstrates worse outcomes among females. METHODS: Using Medicare claims, we performed a retrospective cohort study of adult patients who underwent elective groin hernia repair between January 1, 2010 and December 31, 2017. We used a Cox proportional hazards model to evaluate the risk of operative recurrence up to 5 years following the index operation. Secondary outcomes included 30-day complications following surgery. RESULTS: Among 118,119 patients, females comprised the minority of patients (n=16,056, 13.6%). Compared with males, female patients were older (74.8 vs. 71.9 y, P <0.01), more often white (89.5% vs. 86.7%, P <0.01), and had a higher prevalence of nearly all measured comorbidities. In the multivariable Cox proportional hazards model, we found that female patients had a significantly lower risk of operative recurrence at 5-year follow-up compared with males (aHR 0.70, 95% CI 0.60-0.82). The estimated cumulative incidence of recurrence was lower among females at all time points: 1 year [0.68% (0.67-0.68) vs. 0.88% (0.88-0.89)], 3 years [1.91% (1.89-1.92) vs. 2.49% (2.47-2.5)], and 5 years [2.85% (2.82-2.88) vs. 3.7% (3.68-3.75)]. We found no significant difference in the 30-day risk of complications. CONCLUSIONS: We found that female patients experienced a lower risk of operative hernia recurrence following elective groin hernia repair, which is contrary to what is often reported in the literature. However, the risk of operative recurrence was low overall, indicating excellent surgical outcomes among older adults for this common surgical condition.

High Deductibles are Associated With Severe Disease, Catastrophic Out-of-Pocket Payments for Emergency Surgical Conditions.

BACKGROUND: Out-of-pocket spending has risen for individuals with private health insurance, yet little is known about the unintended consequences that high levels of cost-sharing may have on delayed clinical presentation and financial outcomes for common emergency surgical conditions. METHODS: In this retrospective analysis of claims data from a large commercial insurer (2016-2019), we identified adult inpatient admissions following emergency department presentation for common emergency surgical conditions (eg, appendicitis, cholecystitis, diverticulitis, and intestinal obstruction). Primary exposure of interest was enrollment in a high-deductible health insurance plan (HDHP). Our primary outcome was disease severity at presentation-determined using ICD-10-CM diagnoses codes and based on validated measures of anatomic severity (eg, perforation, abscess, diffuse peritonitis). Our secondary outcome was catastrophic out-of-pocket spending, defined by the World Health Organization as out-of-pocket spending >10% of annual income. RESULTS: Among 43,516 patients [mean age 48.4 (SD: 11.9) years; 51% female], 41% were enrolled HDHPs. Despite being younger, healthier, wealthier, and more educated, HDHP enrollees were more likely to present with more severe disease (28.5% vs 21.3%, P <0.001; odds ratio (OR): 1.34, 95% CI: 1.28-1.42]); even after adjusting for relevant demographics (adjusted OR: 1.23, 95% CI: 1.18-1.31). HDHP enrollees were also more likely to incur 30-day out-of-pocket spending that exceeded 10% of annual income (20.8% vs 6.4%, adjusted OR: 3.93, 95% CI: 3.65-4.24). Lower-income patients, Black patients, and Hispanic patients were at highest risk of financial strain. CONCLUSIONS: For privately insured patients presenting with common surgical emergencies, high-deductible health plans are associated with increased disease severity at admission and a greater financial burden after discharge-especially for vulnerable populations. Strategies are needed to improve financial risk protection for common surgical emergencies.

Out-of-pocket Costs for Commercially-insured Patients in the Years Following Bariatric Surgery: Sleeve Gastrectomy Versus Roux-en-Y Gastric Bypass.

OBJECTIVE: To compare out-of-pocket (OOP) costs for patients up to 3 years after bariatric surgery in a large, commercially-insured population. SUMMARY OF BACKGROUND DATA: More information on OOP costs following bariatric surgery may affect patients' procedure choice. METHODS: Retrospective study using the IBM MarketScan commercial claims database, representing patients nationally who underwent laparoscopic sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) January 1, 2011 to December 31, 2017. We compared total OOP costs after the surgical episode between the 2 procedures using difference-in-differences analysis adjusting for demographics, comorbidities, operative year, and insurance type. RESULTS: Of 63,674 patients, 64% underwent SG and 36% underwent RYGB. Adjusted OOP costs after SG were $1083, $1236, and $1266 postoperative years 1, 2, and 3. For RYGB, adjusted OOP costs were $1228, $1377, and $1369. In our primary analysis, SG OOP costs were $122 (95% confidence interval [CI]: -$155 to -$90) less than RYGB year 1. This difference remained consistent at -$119 (95%CI: -$158 to -$79) year 2 and -$80 (95%CI: -$127 to -$35) year 3. These amounts were equivalent to relative differences of -7%, -7%, and -5% years 1, 2, and 3. Plan features contributing the most to differences were co-insurance years 1, 2, and 3.The largest clinical contributors to differences were endoscopy and outpatient care year 1, outpatient care year 2, and emergency department use year 3. CONCLUSIONS: Our study is the first to examine the association between bariatric surgery procedure and OOP costs. Differences between procedures were approximately $100 per year which may be an important factor for some patients deciding whether to pursue SG or gastric bypass.

Comparative Safety of Sleeve Gastrectomy and Gastric Bypass up to 5 Years After Surgery in Patients With Medicaid.

OBJECTIVE: Compare adverse outcomes up to 5 years after sleeve gastrectomy and gastric bypass in patients with Medicaid. BACKGROUND: Sleeve gastrectomy is the most common bariatric operation among patients with Medicaid; however, its long-term safety in this population is unknown. METHODS: Using Medicaid claims, we performed a retrospective cohort study of adult patients who underwent sleeve gastrectomy or gastric bypass from January 1, 2012, to December 31, 2018. Instrumental variables survival analysis was used to estimate the cumulative incidence and heterogeneity of outcomes up to 5 years after surgery. RESULTS: Among 132,788 patients with Medicaid, 84,717 (63.8%) underwent sleeve gastrectomy and 48,071 (36.2%) underwent gastric bypass. A total of 69,225 (52.1%) patients were White, 33,833 (25.5%) were Black, and 29,730 (22.4%) were Hispanic. Compared with gastric bypass, sleeve gastrectomy was associated with a lower 5-year cumulative incidence of mortality (1.29% vs 2.15%), complications (11.5% vs 16.2%), hospitalization (43.7% vs 53.7%), emergency department (ED) use (61.6% vs 68.2%), and reoperation (18.5% vs 22.8%), but a higher cumulative incidence of revision (3.3% vs 2.0%). Compared with White patients, the magnitude of the difference between sleeve and bypass was smaller among Black patients for ED use [5-y adjusted hazard ratios: 1.01; 95% confidence interval (CI), 0.94-1.08 vs 0.94 (95% CI, 0.88-1.00), P <0.001] and Hispanic patients for reoperation [5-y adjusted hazard ratios: 0.95 (95% CI, 0.86-1.05) vs 0.76 (95% CI, 0.69-0.83), P <0.001]. CONCLUSIONS: Among patients with Medicaid undergoing bariatric surgery, sleeve gastrectomy was associated with a lower risk of mortality, complications, hospitalization, ED use, and reoperations, but a higher risk of revision compared with gastric bypass. Although the difference between sleeve and bypass was generally similar among White, Black, and Hispanic patients, the magnitude of this difference was smaller among Black patients for ED use and Hispanic patients for reoperation.

Births After Bariatric Surgery in the United States: Incidence, Obstetric Outcomes, and Reinterventions.

OBJECTIVE: To characterize incidence and outcomes for bariatric surgery patients who give birth. BACKGROUND: Patients of childbearing age comprise 65% of bariatric surgery patients in the United States, yet data on how often patients conceive and obstetric outcomes are limited. METHODS: Using the IBM MarketScan database, we performed a retrospective cohort study of female patients ages 18 to 52 undergoing laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass from 2011 to 2017. We determined the incidence of births in the first 2 years after bariatric surgery using Kaplan-Meier estimates. We then restricted the cohort to those with a full 2-year follow-up to examine obstetric outcomes and bariatric-related reinterventions. We reported event rates of adverse obstetric outcomes and delivery type. Adverse obstetric outcomes include pregnancy complications, severe maternal morbidity, and delivery complications. We performed multivariable logistic regression to examine associations between birth and risk of reinterventions. RESULTS: Of 69,503 patients who underwent bariatric surgery, 1464 gave birth. The incidence rate was 2.5 births per 100 patients in the 2 years after surgery. Overall, 85% of births occurred within 21 months after surgery. For 38,922 patients with full 2-year follow-up, adverse obstetric event rates were 4.5% for gestational diabetes and 14.2% for hypertensive disorders. In all, 48.5% were first-time cesarean deliveries. Almost all reinterventions during pregnancy were biliary. Multivariable logistic regression analysis showed no association between postbariatric birth and reintervention rate (odds ratio: 0.93, 95% confidence interval: 0.78-1.12). CONCLUSIONS: In this first national US cohort, we find giving birth was common in the first 2 years after bariatric surgery and was not associated with an increased risk of reinterventions. Clinicians should consider shifting the dialogue surrounding pregnancy after surgery to shared decision-making with maternal safety as one component.

Postacute Care Utilization and Episode of Care Payments Following Common Elective Operations.

OBJECTIVE: To describe PAC utilization and associated payments for patients undergoing common elective procedures. SUMMARY OF BACKGROUND DATA: Utilization and costs of PAC are well described for benchmarked conditions and operations but remain understudied for common elective procedures. METHODS: Cross-sectional study of adult patients in a statewide administrative claims database undergoing elective cholecystectomy, ventral or incisional hernia repair (VIHR), and groin hernia repair from 2012 to 2019. We used multivariable logistic regression to estimate the odds of PAC utilization, and multivariable linear regression to determine the association of 90-day episode of care payments and PAC utilization. RESULTS: Among 34,717 patients undergoing elective cholecystectomy, 0.7% utilized PAC resulting in significantly higher payments ($19,047 vs $7830, P < 0.001). Among 29,826 patients undergoing VIHR, 1.7% utilized PAC resulting in significantly higher payments ($19,766 vs $9439, P < 0.001). Among 37,006 patients undergoing groin hernia repair, 0.3% utilized PAC services resulting in significantly higher payments ($14,886 vs $8062, P < 0.001). We found both modifiable and non-modifiable risk factors associated with PAC utilization. Morbid obesity was associated with PAC utilization following VIHR [odds ratio (OR) 1.61, 95% confidence interval (CI) 1.29-2.02, P < 0.001]. Male sex was associated with lower odds of PAC utilization for VIHR (OR 0.43, 95% CI 0.35-0.51, P < 0.001) and groin hernia repair (OR 0.62, 95% CI 0.39-0.98, P = 0.039). CONCLUSIONS: We found both modifiable (eg, obesity) and nonmodifiable (eg, female sex) patient factors that were associated with PAC. Optimizing patients to reduce PAC utilization requires an understanding of patient risk factors and systems and processes to address these factors.

Surgical Leadership Competencies for Navigating Hospital Network Expansion.

INTRODUCTION: Today, many hospitals are part of a multihospital network, which changes the context in which surgeons are asked to lead. This study explores key leadership competencies that surgical leaders use to navigate this hospital network expansion. METHODS: In this qualitative study, 30 surgical leaders were interviewed. Interviews were coded and analyzed via thematic analysis. RESULTS: We identified three key competencies that leaders felt were important leadership skills to successfully navigate expanding hospital networks. First, leaders must steer the departmental vision within the evolving hospital network landscape. Second, leaders must align the visions of the department and of the hospital network. Third, leaders must build a network-oriented culture within their department. CONCLUSIONS: As networks expand, leaders are tasked with unifying vision in their department. Leaders identified a unique opportunity to leverage their growing influence across the hospital network and invested in the people and culture of their department.
