Costs of Care for Operative and Nonoperative Management of Emergency General Surgery Conditions.

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.

Inefficiencies of care in hub and spoke healthcare systems: A multi-state cohort study.

BACKGROUND: Complex surgical care is often centralized to one high volume (hub) hospital within a system. The benefit of this centralization in common operations is unknown. METHODS: Using the Healthcare Cost and Utilization Project's State Inpatient Databases, adult general surgical patients within hospital systems in 13 states (2016-2018) were identified. Risk-adjusted logistic regression estimated the odds of death or serious morbidity (DSM) and prolonged length of stay (LOS) at hubs relative to other system hospitals (spokes). RESULTS: We identified 122,895 patients across 43 hub-and-spoke systems. Hubs completed 83.2 â€‹% of complex and 59.6 â€‹% of common operations. For complex operations, odds of DSM were significantly lower in hubs (OR: 0.80; 95 â€‹% CI [0.65, 0.98]). For common operations, odds of DSM were similar between hubs and spokes, while odds of prolonged LOS were greater at hubs (OR 1.19; 95 â€‹% CI [1.16,1.24]). CONCLUSIONS: While hub hospitals had lower odds of DSM for complex operation, they had higher odds of prolonged length of stay for common operations. This finding shows an opportunity for improved system efficiency.

Development of a risk-prediction model for primary aldosteronism in veterans with hypertension.

BACKGROUND: Rates of screening for primary aldosteronism in patients who meet the criteria are exceedingly low (1%-3%). To help clinicians prioritize screening in patients most likely to benefit, we developed a risk-prediction model. METHODS: Using national Veterans Health Administration data, we identified patients who met the criteria for primary aldosteronism screening between 2000 and 2019. We performed multivariable logistic regression to identify characteristics associated with positive primary aldosteronism testing before generating a risk-scoring system based on the coefficients (0< ß < 0.5 = 1 pt, 0.5 ≤ ß < 1 = 2 pts, 1 ≤ ß < 1.5 = 3 pts) and then tested the system performance using an internal validation cohort. RESULTS: We identified 502,190 patients who met primary aldosteronism screening criteria, of whom 1.6% were screened and 15% tested positive. Based on the regression model, we generated a risk-scoring system based on a total of 9 possible points in which age under 50, absence of smoking history, and resistant hypertension each scored 1 point; elevated serum sodium 2 points; and hypokalemia 3 points. Rates of positive screening increased with risk score, with 5.6% to 6.7% of those scoring 0 points testing positive; 7.9% to 9.0% 1 point; 8.6% to 10% 2 points; 13% to 14% 3 points; 21% 4 points; 22% to 38% 5 points; 27% to 38% 6 points; 42% to 49% 7 points; and 50% to 51% ≥8 points. CONCLUSION: In hypertensive patients who meet the criteria for primary aldosteronism screening, rates of positive screening range from 5.6% to 51%. Use of our risk-predication model incorporating these factors can identify patients most likely to benefit from testing.

An acute care surgeon's dilemma: Operative vs. non-operative management of emergency general surgery conditions in patients with recent colorectal cancer treatment.

BACKGROUND: This comparative effectiveness study examined outcomes of operative vs. non-operative management for emergency general surgery (EGS) conditions in patients with recent cancer treatment (RT). METHODS: Medicare beneficiaries with a history of colorectal cancer hospitalized for an EGS condition (2016-2018) were identified. RT was defined as chemotherapy/radiation within 3 months prior to admission. Instrumental variable analysis assessed the impact of management on mortality and readmissions among survivors (30d, 60d, and 90d), for patients in whom there was clinical equipoise regarding optimal management strategy. RESULTS: Of 26,097 patients, 13% had undergone RT. In both the RT and non-RT groups, the optimal management strategy was uncertain in 14%. Operative management conferred increased risk of mortality but not readmission in patients with RT compared to those without (90d mortality:+43%, p â€‹= â€‹0.03; 90d readmission:+7.1%, p â€‹= â€‹0.776). CONCLUSIONS: In patients with RT for whom there is clinical equipoise regarding EGS management, operative intervention increases risk of mortality.

Variation in Hospital Performance for General Surgery in Younger and Older Adults: A Retrospective Cohort Study.

OBJECTIVE: To compare hospital surgical performance in older and younger patients. SUMMARY BACKGROUND DATA: In-hospital mortality after surgical procedures varies widely between hospitals. Prior studies suggest that failure-to-rescue rates drive this variation for older adults, but the generalizability of these findings to younger patients remains unknown. METHODS: We performed a retrospective cohort study of patients ≥18 years undergoing one of ten common and complex general surgery operations in 16 states using the Healthcare Cost and Utilization Projects State Inpatient Databases (2016-2018). Patients were split into two populations: Medicare ≥65 (older adult) and non-Medicare <65 (younger adult) patients. Hospitals were sorted into quintiles using risk-adjusted in-hospital mortality rates for each age population. Correlations between hospitals in each mortality quintile across age populations were calculated. Complication and failure-to-rescue rates were compared across the highest and lowest mortality quintiles in each age population. RESULTS: We identified 579,582 patients treated in 732 hospitals. The mortality rate was 3.6% among older adults and 0.7% among younger adults. Among older adults, high- relative to low-mortality hospitals had similar complication rates (32.0% vs. 29.8%; P=0.059) and significantly higher failure-to-rescue rates (16.0% vs. 4.0%; P<0.001). Among younger adults, high- relative to low-mortality hospitals had higher complication (15.4% vs. 12.1%; P<0.001) and failure-to-rescue rates (8.3% vs. 0.7%; P<0.001). The correlation between observed-to-expected mortality ratios in each age group was 0.385 (P<0.001). CONCLUSIONS: High surgical mortality rates in younger patients may be driven by both complication and failure-to-rescue rates. There is little overlap between low-mortality hospitals in the older and younger adult populations. Future work must delve into the root causes of this age-based difference in hospital-level surgical outcomes.

Primary Care Physician Follow-Up and 30-Day Readmission After Emergency General Surgery Admissions.

Importance: The benefit of primary care physician (PCP) follow-up as a potential means to reduce readmissions in hospitalized patients has been found in other medical conditions and among patients receiving high-risk surgery. However, little is known about the implications of PCP follow-up for patients with an emergency general surgery (EGS) condition. Objective: To evaluate the association between PCP follow-up and 30-day readmission rates after hospital discharge for an EGS condition. Design, Setting, and Participants: This cohort study used data from the Centers for Medicare & Medicaid Services Master Beneficiary Summary File, Inpatient, Carrier (Part B), and Durable Medical Equipment files for beneficiaries aged 66 years or older who were hospitalized with an EGS condition that was managed operatively or nonoperatively between September 1, 2016, and November 30, 2018. Eligible patients were enrolled in Medicare fee-for-service, admitted through the emergency department with a primary diagnosis of an EGS condition, and received a general surgery consultation during the admission. Data were analyzed between July 11, 2022, and June 5, 2023. Exposure: Follow-up with a PCP within 30 days after hospital discharge for the index admission. Main Outcomes and Measures: The primary outcome was readmission within 30 days after discharge for the index admission. An inverse probability weighted regression model was used to estimate the risk-adjusted association of PCP follow-up with 30-day readmission. The secondary outcome was readmission within 30 days after discharge stratified by treatment type (operative vs nonoperative treatment) during their index admission. Results: The study included 345 360 Medicare beneficiaries (mean [SD] age, 74.4 [12.0] years; 187 804 females [54.4%]) hospitalized with an EGS condition. Of these, 156 820 patients (45.4%) had a follow-up PCP visit, 108 544 (31.4%) received operative treatment during their index admission, and 236 816 (68.6%) received nonoperative treatment. Overall, 58 253 of 332 874 patients (17.5%) were readmitted within 30 days after discharge for the index admission. After risk adjustment and propensity weighting, patients who had PCP follow-up had 67% lower odds of readmission (adjusted odds ratio [AOR], 0.33; 95% CI, 0.31-0.36) compared with patients without PCP follow-up. After stratifying by treatment type, patients who were treated operatively during their index admission and had subsequent PCP follow-up within 30 days after discharge had 79% reduced odds of readmission (AOR, 0.21; 95% CI, 0.18-0.25); a similar association was seen among patients who were treated nonoperatively (AOR, 0.36; 95% CI, 0.34-0.39). Infectious conditions, heart failure, acute kidney failure, and chronic kidney disease were among the most frequent diagnoses prompting readmission overall and among operative and nonoperative treatment groups. Conclusions and Relevance: In this cohort study, follow-up with a PCP within 30 days after discharge for an EGS condition was associated with a significant reduction in the adjusted odds of 30-day readmission. This association was similar for patients who received operative care or nonoperative care during their index admission. In patients aged 66 years or older with an EGS condition, primary care coordination after discharge may be an important tool to reduce readmissions.

Conditional Effects of Race on Operative and Nonoperative Outcomes of Emergency General Surgery Conditions.

INTRODUCTION: Many emergency general surgery (EGS) conditions can be managed both operatively or nonoperatively; however, it is unknown whether the decision to operate affects Black and White patients differentially. METHODS: We identified a nationwide cohort of Black and White Medicare beneficiaries, hospitalized for common EGS conditions from July 2015 to June 2018. Using near-far matching to adjust for measurable confounding and an instrumental variable analysis to control for selection bias associated with treatment assignment, we compare outcomes of operative and nonoperative management in a stratified population of Black and White patients. Outcomes included in-hospital mortality, 30-day mortality, nonroutine discharge, and 30-day readmissions. An interaction test based on a t test was used to determine the conditional effects of operative versus nonoperative management between Black and White patients. RESULTS: A total of 556,087 patients met inclusion criteria, of which 59,519 (10.7%) were Black and 496,568 (89.3%) were White. Overall, 165,932 (29.8%) patients had an operation and 390,155 (70.2%) were managed nonoperatively. Significant outcome differences were seen between operative and nonoperative management for some conditions; however, no significant differences were seen for the conditional effect of race on outcomes. CONCLUSIONS: The decision to manage an EGS patient operatively versus nonoperatively has varying effects on surgical outcomes. These effects vary by EGS condition. There were no significant conditional effects of race on the outcomes of operative versus nonoperative management among universally insured older adults hospitalized with EGS conditions.

Association of Established Primary Care Use With Postoperative Mortality Following Emergency General Surgery Procedures.

Importance: Sixty-five million individuals in the US live in primary care shortage areas with nearly one-third of Medicare patients in need of a primary care health care professional. Periodic health examinations and preventive care visits have demonstrated a benefit for surgical patients; however, the impact of primary care health care professional shortages on adverse outcomes from surgery is largely unknown. Objective: To determine if preoperative primary care utilization is associated with postoperative mortality following an emergency general surgery (EGS) operation among Black and White older adults. Design, Setting, and Participants: This was a retrospective cohort study that took place at US hospitals with an emergency department. Participants were Medicare patients aged 66 years or older who were admitted from the emergency department for an EGS condition between July 1, 2015, and June 30, 2018, and underwent an operation on hospital day 0, 1, or 2. The analysis was performed during December 2022. Patients were classified into 1 of 5 EGS condition categories based on principal diagnosis codes; colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, or upper gastrointestinal. Mixed-effects multivariable logistic regression was used in the risk-adjusted models. An interaction term model was used to measure effect modification by race. Exposure: Primary care utilization in the year prior to presentation for an EGS operation. Main Outcome and Measures: In-hospital, 30-day, 60-day, 90-day, and 180-day mortality. Results: A total of 102 384 patients (mean age, 73.8 [SD, 11.5] years) were included in the study. Of those, 8559 were Black (8.4%) and 93 825 were White (91.6%). A total of 88 340 patients (86.3%) had seen a primary care physician in the year prior to their index hospitalization. After risk adjustment, patients with primary care exposure had 19% lower odds of in-hospital mortality than patients without primary care exposure (odds ratio [OR], 0.81; 95% CI, 0.72-0.92). At 30 days patients with primary care exposure had 27% lower odds of mortality (OR, 0.73; 95% CI, 0.67-0.80). This remained relatively stable at 60 days (OR, 0.75; 95% CI, 0.69-0.81), 90 days (OR, 0.74; 95% CI, 0.69-0.81), and 180 days (OR, 0.75; 95% CI, 0.70-0.81). None of the interactions between race and primary care physician exposure for mortality at any time interval were significantly different. Conclusions and Relevance: In this observational study of Black and White Medicare patients, primary care utilization had no impact on in-hospital mortality for Black patients, but was associated with decreased mortality for White patients. Primary care utilization was associated with decreased mortality for both Black and White patients at 30, 60, 90 and 180 days.

National Cohort Study of Resource Utilization in Older Adults With Emergency General Surgery Conditions.

INTRODUCTION: Prior studies have sought to describe Emergency General Surgery (EGS) burden, but a detailed description of resource utilization for both operative and nonoperative management of EGS conditions has not been undertaken. METHODS: Patient and hospital characteristics were extracted from Medicare data, 2015-2018. Operations, nonsurgical procedures, and other resources (i.e., radiology) were defined using Current Procedural Terminology codes. RESULTS: One million eight hundred two thousand five hundred forty-five patients were included in the cohort. The mean age was 74.7 y and the most common diagnoses were upper gastrointestinal. The majority of hospitals were metropolitan (75.1%). Therapeutic radiology services were available in 78.4% of hospitals and operating rooms or endoscopy suites were available in 92.5% of hospitals. There was variability in resource utilization across EGS subconditions, with hepatobiliary (26.4%) and obstruction (23.9%) patients most frequently undergoing operation. CONCLUSIONS: Treatment of EGS diseases in older adults involves several interventional resources. Changes in EGS models, acute care surgery training, and interhospital care coordination may be beneficial to the treatment of EGS patients.

Impact of Medicaid expansion on outcomes after abdominal aortic aneurysm repair.

OBJECTIVE: Lack of insurance has been independently associated with an increased risk of in-hospital mortality after abdominal aortic aneurysm repair, possibly due to worse control of comorbidities and delays in diagnosis and treatment. Medicaid expansion has improved insurance rates and access to care, potentially benefiting these patients. We sought to assess the association between Medicaid expansion and outcomes after abdominal aortic aneurysm repair. METHODS: A retrospective analysis of Healthcare Cost and Utilization Project State Inpatient Databases data from 14 states between 2012 and 2018 was conducted. The sample was restricted to first-record abdominal aortic aneurysm repairs in adults under age 65 in states that expanded Medicaid on January 1, 2014 (Medicaid expansion group) or had not expanded before December 31, 2018 (non-expansion group). The Medicaid expansion and non-expansion groups were compared between pre-expansion (2012-2013) and post-expansion (2014-2018) time periods to assess baseline demographic and operative differences. We used difference-in-differences multivariable logistic regression adjusted for patient factors, open vs endovascular repair, and standard errors clustered by state. Our primary outcome was in-hospital mortality. Outcomes were stratified by insurance type. RESULTS: We examined 8995 patients undergoing abdominal aortic aneurysm repair, including 3789 (42.1%) in non-expansion states and 5206 (57.9%) in Medicaid expansion states. Rates of Medicaid insurance were unchanged in non-expansion states but increased in Medicaid expansion states post-expansion (non-expansion: 10.9% to 9.8%; P = .346; expansion: 9.7% to 19.7%; P < .001). One in 10 patients from both non-expansion and Medicaid expansion states presented with ruptured aneurysms, which did not change over time. Rates of open repair decreased in both non-expansion and Medicaid expansion states over time (non-expansion: 25.1% to 19.2%; P < .001; expansion: 25.2% to 18.4%; P < .001). On adjusted difference-in-differences analysis between expansion and non-expansion states pre-to post-expansion, Medicaid expansion was associated with a 1.02% absolute reduction in in-hospital mortality among all patients (95% confidence interval, -1.87% to -0.17%; P = .019). Additionally, among patients who were either on Medicaid or were uninsured (ie, the patients most likely to be impacted by Medicaid expansion), a larger 4.17% decrease in in-hospital mortality was observed (95% confidence interval, -6.47% to -1.87%; P < .001). In contrast, no significant difference-in-difference in mortality was observed for privately insured patients. CONCLUSIONS: Medicaid expansion was associated with decreased in-hospital mortality after abdominal aortic aneurysm repair among all patients and particularly among patients who were either on Medicaid or were uninsured. Our results provide support for improved access to care for patients undergoing abdominal aortic aneurysm repair through Medicaid expansion.

Racial and Ethnic Disparities in Appropriate Thyroid Cancer Treatment, Before and After the Release of the 2015 American Thyroid Association Guidelines.

BACKGROUND: The 2015 American Thyroid Association (ATA) guidelines reduced the recommended extent of therapy for low-risk thyroid cancers. Little is known about the impact of these changes on overall treatment patterns and on previously described racial/ethnic disparities in guideline-concordant care. This study aimed to assess trends in thyroid cancer care before and after release of the 2015 guidelines, with particular attention to racial/ethnic disparities. METHODS: Patients with well-differentiated thyroid cancer were identified from the National Cancer Database (2010-2018). An interrupted time series design was used to assess trends in treatment before and after the 2015 guidelines. Appropriateness of surgical and radioactive iodine (RAI) treatment was determined based on the ATA guidelines, and the likelihood of receiving guideline-concordant treatment was compared between racial/ethnic groups. RESULTS: The study identified 309,367 patients (White 74%, Black 8%, Hispanic 9%, Asian 6%). Between 2010 and 2015, the adjusted probability of appropriate surgery was lower for Black (- 2.1%; p < 0.001), Hispanic (- 1.0%; p < 0.001), and Asian (- 2.1%; p < 0.001) patients than for White patients. After 2015, only Hispanic patients had a lower probability of undergoing appropriate surgical therapy (- 2.6%; p = 0.040). Similarly, between 2010 and 2015, the adjusted probability of receiving appropriate RAI therapy was lower for the Hispanic (- 3.6%; p < 0.001) and Asian (- 2.4%; p < 0.001) patients than for White patients. After 2015, the probability of appropriate RAI therapy did not differ between groups. CONCLUSIONS: Between 2010 and 2015, patients from racial/ethnic minority backgrounds were less likely than White patients to receive appropriate surgical and RAI therapy for thyroid cancer. After the 2015 guidelines, racial/ethnic disparities in treatment improved.

Health System Structure: An Opportunity to Address Structural Racism and Discrimination.

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.

Examining disparities among older multimorbid emergency general surgery patients: An observational study of Medicare beneficiaries.

BACKGROUND: Qualifying comorbidity sets (QCS) are tools used to identify multimorbid patients at increased surgical risk. It is unknown how the QCS framework for multimorbidity affects surgical risk in different racial groups. METHODS: This retrospective cohort study included Medicare patients age ≥65.5 who underwent an emergency general surgery operation from 2015 to 2018. Our exposure was race and multimorbidity, included in our model as an interaction term. The primary outcome of the study was 30-day mortality. Secondary outcomes included routine discharge, 30-day readmission, length of stay, and complications. RESULTS: In total, 163,148 patients who underwent and operation were included in this study. Of these, 13,852 (8.5%, p < 0.001) were Black, and 149,296 (91.5%, p < 0.001) were White. Black multimorbid patients had no significant differences in 30-day mortality, routine discharge or 30-day readmission when compared to White multimorbid patients after risk-adjustment. Black multimorbid patients had significantly lower odds of complications (OR 0.89, p = 0.014) compared to White multimorbid patients. CONCLUSIONS: Our study of universally insured patients highlights the critical role of pre-operative health status and its association with surgical outcomes.

Operative and Nonoperative Outcomes of Emergency General Surgery Conditions: An Observational Study Using a Novel Instrumental Variable.

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.

Rates of Surgical Consultations After Emergency Department Admission in Black and White Medicare Patients.

Importance: A surgical consultation is a critical first step in the care of patients with emergency general surgery conditions. It is unknown if Black Medicare patients and White Medicare patients receive surgical consultations at similar rates when they are admitted from the emergency department. Objective: To determine whether Black Medicare patients have similar rates of surgical consultations when compared with White Medicare patients after being admitted from the emergency department with an emergency general surgery condition. Design, Setting, and Participants: This was a retrospective cohort study that took place at US hospitals with an emergency department and used a computational generalization of inverse propensity score weight to create patient populations with similar covariate distributions. Participants were Medicare patients age 65.5 years or older admitted from the emergency department for an emergency general surgery condition between July 1, 2015, and June 30, 2018. The analysis was performed during February 2022. Patients were classified into 1 of 5 emergency general surgery condition categories based on principal diagnosis codes: colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, and upper gastrointestinal. Exposures: Black vs White race. Main Outcomes and Measures: Receipt of a surgical consultation after admission from the emergency department with an emergency general surgery condition. Results: A total of 1 686 940 patients were included in the study. Of those included, 214 788 patients were Black (12.7%) and 1 472 152 patients were White (87.3%). After standardizing for medical and diagnostic imaging covariates, Black patients had 14% lower odds of receiving a surgical consultation (odds ratio [OR], 0.86; 95% CI, 0.85-0.87) with a risk difference of -3.17 (95% CI, -3.41 to -2.92). After standardizing for socioeconomic covariates, Black patients remained at an 11% lower odds of receiving a surgical consultation compared with similar White patients (OR, 0.89; 95% CI, 0.88-0.90) with a risk difference of -2.49 (95% CI, -2.75 to -2.23). Additionally, when restricting the analysis to Black patients and White patients who were treated in the same hospitals, Black patients had 8% lower odds of receiving a surgical consultation when compared with White patients (OR, 0.92; 95% CI, 0.90-0.93) with a risk difference of -1.82 (95% CI, -2.18 to -1.46). Conclusions and Relevance: In this study, Black Medicare patients had lower odds of receiving a surgical consultation after being admitted from the emergency department with an emergency general surgery condition when compared with similar White Medicare patients. These disparities in consultation rates cannot be fully attributed to medical comorbidities, insurance status, socioeconomic factors, or individual hospital-level effects.

The Effects of the Affordable Care Act on Utilization of Bariatric Surgery.

INTRODUCTION: The Affordable Care Act (ACA) expanded Medicaid (ME) and instituted Essential Health Benefits (EHB) that included bariatric surgery coverage on a state-by-state opt-in basis, increasing insurance coverage of bariatric surgery. MATERIALS AND METHODS: Using a difference-in-differences framework, changes in bariatric surgery rates, defined as utilization in the population of people with obesity, before and after the ACA were evaluated in four states. Bariatric surgery procedure data were taken from the Healthcare Cost and Utilization Project's State In-patient Database 2012-2015. Adjusted multivariable regressions were run in the Medicaid and commercially insured populations. RESULTS: We identified 36,456 bariatric surgeries across the 286 Health Service Areas and time periods, with 31,732 covered by commercial insurers and 4724 covered by Medicaid. An unadjusted increase in utilization rates was seen in the Medicaid and Commercial populations in both ME- and EHB-covered states as well as non-expansion and EHB opt-out states over time. In the Medicaid population, after adjusting for confounders, there was a significant increase of 24.77 cases per 100,000 people with obesity (95% confidence interval: 12.41, 37.13) in the expansion states relative to the control and pre-period. The commercial population experienced a nonsignificant change in the rates of bariatric surgery, decreasing by 2.89 cases per 100,000 people with obesity (95% confidence interval: - 21.59, 15.81). CONCLUSIONS: There was a significant increase in bariatric surgery rates among Medicaid beneficiaries associated with Medicaid expansion, but there was no change among the commercially insured.

Does Surgeon Sex Matter?: Practice Patterns and Outcomes of Female and Male Surgeons.

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.

Hospitalization in the Year Preceding Major Oncologic Surgery Increases Risk for Adverse Postoperative Events.

BACKGROUND: Hospitalization is associated with negative clinical effects that last beyond discharge. This study aimed to determine whether hospitalization in the year before major oncologic surgery is associated with adverse outcomes. METHODS: Patients 18 years of age or older with stomach, pancreas, colon, or rectal cancer who underwent resection in California and New York (2008-2010) were included in the study. Patients with hospitalization in the year prior to oncologic resection (HYPOR) were identified. Multivariable logistic regression was used to examine the association of prior hospitalization with the following adverse outcomes: inpatient mortality, complications, complex discharge needs, and 90-day readmission. Subset analysis by cancer type was performed. Outcomes based on temporal proximity of hospitalization to month of surgical admission were evaluated. RESULTS: Of 32,292 patients, 16.3% (n = 5276) were HYPOR. Patients with prior hospitalization were older (median age, 72 vs 67 years; p < 0.001) and had more comorbidities (Elixhauser Index ≥3, 86.5 vs 75.3%; p < 0.001). In the multivariable analysis, HYPOR was associated with complications (odds ratio [OR], 1.28; 95% confidence interval [CI] 1.18-1.40), complex discharge (OR, 1.44; 95% CI 1.34-1.55), and 90-day readmission (OR, 1.45; 95% CI 1.35-1.56). The interval from HYPOR to resection was not associated with adverse outcomes. CONCLUSIONS: Patients hospitalized in the year before oncologic resection are at increased risk for postoperative adverse events. Recent hospitalization is a risk factor that is easily ascertainable and should be used by clinicians to identify patients who may need additional support around the time of oncologic resection.

Outcomes of hospitalized patients undergoing emergency general surgery remote from admission.

BACKGROUND: Emergency general surgery during hospitalization has not been well characterized. We examined emergency operations remote from admission to identify predictors of postoperative 30-day mortality, postoperative duration of stay >30 days, and complications. METHODS: Patients >18 years in The American College of Surgeons National Surgical Quality Improvement Program (2011-2014) who had 1 of 7 emergency operations between hospital day 3-18 were included. Patients with operations >95th percentile after admission (>18 days; n = 581) were excluded. Exploratory laparotomy only (with no secondary procedure) represented either nontherapeutic or decompressive laparotomy. Multivariable logistic regression was used to identify predictors of study outcomes. RESULTS: Of 10,093 patients with emergency operations, most were elderly (median 66 years old [interquartile ratio: 53-77 years]), white, and female. Postoperative 30-day mortality was 12.6% (n = 1,275). Almost half the cohort (40.1%) had a complication. A small subset (6.8%) had postoperative duration of stay >30 days. Postoperative mortality after exploratory laparotomy only was particularly high (>40%). In multivariable analysis, an operation on hospital day 11-18 compared with day 3-6 was associated with death (odds ratio 1.6 [1.3-2.0]), postoperative duration of stay >30 days (odds ratio 2.0 [1.6-2.6]), and complications (odds ratio 1.5 [1.3-1.8]). Exploratory laparotomy only also was associated with death (odds ratio 5.4 [2.8-10.4]). CONCLUSION: Emergency general surgery performed during a hospitalization is associated with high morbidity and mortality. A longer hospital course before an emergency operation is a predictor of poor outcomes, as is undergoing exploratory laparotomy only.
