The influence of primary language on postoperative stroke outcomes.

BACKGROUND: Language barriers have the potential to influence acute stroke outcomes. Thus, we examined postoperative stroke outcomes among non-English primary language speakers. METHODS: Utilizing the Healthcare Cost and Utilization Project State Inpatient Database (2016-2019), we conducted a retrospective cohort study of adults diagnosed with a postoperative stroke in Michigan, Maryland, and New Jersey. Patients were classified by primary language spoken: English (EPL) or non-English (n-EPL). The primary outcome was hospital length-of-stay. Secondary outcomes included stroke intervention, feeding tube, tracheostomy, mortality, cost, disposition, and readmission. Propensity-score matching and post-match regression were used to quantify outcomes. RESULTS: Among 3078 postoperative stroke patients, 6.2 â€‹% were n-EPL. There were no differences in length-of-stay or secondary outcomes, except for higher odds of feeding tube placement (OR 1.95, 95 â€‹% CI 1.10-3.47, p â€‹= â€‹0.0227) in n-EPL. CONCLUSIONS: Postoperative stroke outcomes were comparable by primary language spoken. However, higher odds of feeding tube placement in n-EPL may suggest differences in patient-provider communication.

Impact of Hospital Affiliation With a Flagship Hospital System on Surgical Outcomes.

OBJECTIVE: To compare general surgery outcomes at flagship systems, flagship hospitals, and flagship hospital affiliates versus matched controls. SUMMARY BACKGROUND DATA: It is unknown whether flagship hospitals perform better than flagship hospital affiliates for surgical patients. METHODS: Using Medicare claims for 2018 to 2019, we matched patients undergoing inpatient general surgery in flagship system hospitals to controls who underwent the same procedure at hospitals outside the system but within the same region. We defined a "flagship hospital" within each region as the major teaching hospital with the highest patient volume that is also part of a hospital system; its system was labeled a "flagship system." We performed 4 main comparisons: patients treated at any flagship system hospital versus hospitals outside the flagship system; flagship hospitals versus hospitals outside the flagship system; flagship hospital affiliates versus hospitals outside the flagship system; and flagship hospitals versus affiliate hospitals. Our primary outcome was 30-day mortality. RESULTS: We formed 32,228 closely matched pairs across 35 regions. Patients at flagship system hospitals (32,228 pairs) had lower 30-day mortality than matched control patients [3.79% vs. 4.36%, difference=-0.57% (-0.86%, -0.28%), P<0.001]. Similarly, patients at flagship hospitals (15,571/32,228 pairs) had lower mortality than control patients. However, patients at flagship hospital affiliates (16,657/32,228 pairs) had similar mortality to matched controls. Flagship hospitals had lower mortality than affiliate hospitals [difference-in-differences=-1.05% (-1.62%, -0.47%), P<0.001]. CONCLUSIONS: Patients treated at flagship hospitals had significantly lower mortality rates than those treated at flagship hospital affiliates. Hence, flagship system affiliation does not alone imply better surgical outcomes.

Should I See You Again Soon? A Multispecialty Assessment of the Impact and Burden of Preoperative History and Physical Update Visits.

BACKGROUND: Federal regulations require a history and physical (H&P) update performed ≤30 days before a planned procedure. We evaluated the utility and burdens of H&P update visits by determining impact on operative management, suitability for telehealth, and visit time and travel burden. STUDY DESIGN: We identified H&P update visits performed in our health system during 2019 for 8 surgical specialties. As available, up to 50 visits per specialty were randomly selected. Primary outcomes were a) interval changes in history, exam, or operative plan between the initial and updated H&P notes and b) visit suitability for telehealth, as determined by two independent physician reviewers. Clinic time was captured, and round-trip driving time and distance between patients' home and clinic ZIP codes were estimated. RESULTS: We identified 8,683 visits and 362 were randomly selected for review. Documented changes were most commonly identified in histories (60.8%), but rarely in physical exams (11.9%) and operative plans (11.6%). 99.2% of visits were considered suitable for telehealth. Median clinic time was 52 minutes (IQR:33.8-78), driving time was 55.6 minutes (IQR:35.5-85.5), and driving distance was 20.2 miles (IQR:8.5-38.4). At the health system level, patients spent an estimated aggregate 7,000 hours (including 4,046 hours of waiting room and travel time) and drove 142,273 miles to attend in-person H&P update visits in 2019. CONCLUSION: Given their minimal impact on operative management, regulatory requirements for in-person H&P updates should be reconsidered. Flexibility in update timing and modality might help defray the substantial burdens these visits impose on patients.

Modern Trends for Primary Hyperparathyroidism: Intervening on Less Biochemically Severe Disease.

INTRODUCTION: Primary hyperparathyroidism (PHPT) is defined by autonomous parathyroid hormone secretion, which has broad physiologic effects. Parathyroidectomy is the only cure and is recommended for patients demonstrating symptomatic disease and/or end organ damage. However, there may be a benefit to intervening before the development of complications. We sought to characterize institutional trends in the biochemical and symptomatic presentation of PHPT and the associated cure and complication rates. METHODS: We performed a retrospective cohort study of 1087 patients undergoing parathyroidectomy for PHPT, evaluating patients at 2-year intervals between 2002 and 2019. We identified signs and symptoms of PHPT based on the 2016 American Association of Endocrine Surgery Guidelines. Trends were evaluated with Kruskal Wallis, Chi-square tests, and Fisher's exact tests. RESULTS: Patients with PHPT are presenting with lower parathyroid hormone (P = 0.0001) and calcium (P = 0.001) in the current era. Parathyroidectomy is more commonly performed for borderline guideline concordant patients with osteopenia (40.2%) and modest calciuria (median 246 mg/dL/24 h). 93.7% are cured, with no difference over time or between groups by guideline concordance. CONCLUSIONS: Parathyroidectomy is increasingly performed for patients who demonstrate modest bone and renal dysfunction. Patients experience excellent cure rates and rarely experience postoperative hypocalcemia, suggesting a role for broader surgical indications.

Sex differences and racial/ethnic disparities in the presentation and treatment of medullary thyroid cancer.

BACKGROUND: This study assessed for disparities in the presentation and management of medullary thyroid cancer (MTC). METHODS: Patients with MTC (2010-2020) were identified from the National Cancer Database. Differences in disease presentation and likelihood of guideline-concordant surgical management (total thyroidectomy and resection of ≥1 lymph node) were assessed by sex and race/ethnicity. RESULTS: Of 6154 patients, 68.2% underwent guideline-concordant surgery. Tumors >4 â€‹cm were more likely in men (vs. women: OR 2.47, p â€‹< â€‹0.001) and Hispanic patients (vs. White patients: OR 1.52, p â€‹= â€‹0.001). Non-White patients were more likely to have distant metastases (Black: OR 1.63, p â€‹= â€‹0.002; Hispanic: OR 1.44, p â€‹= â€‹0.038) and experienced longer time to surgery (Black: HR 0.66, p â€‹< â€‹0.001; Hispanic: HR 0.71, p â€‹< â€‹0.001). Black patients were less likely to undergo guideline-concordant surgery (OR 0.70, p â€‹= â€‹0.022). CONCLUSIONS: Male and non-White patients with MTC more frequently present with advanced disease, and Black patients are less likely to undergo guideline-concordant surgery.

Barriers and Facilitators to Clinical Practice Development in Men and Women Surgeons.

Importance: Many early-career surgeons struggle to develop their clinical practices, leading to high rates of burnout and attrition. Furthermore, women in surgery receive fewer, less complex, and less remunerative referrals compared with men. An enhanced understanding of the social and structural barriers to optimal growth and equity in clinical practice development is fundamental to guiding interventions to support academic surgeons. Objective: To identify the barriers and facilitators to clinical practice development with attention to differences related to surgeon gender. Design, Setting, and Participants: A multi-institutional qualitative descriptive study was performed using semistructured interviews analyzed with a grounded theory approach. Interviews were conducted at 5 academic medical centers in the US between July 12, 2022, and January 31, 2023. Surgeons with at least 1 year of independent practice experience were selected using purposeful sampling to obtain a representative sample by gender, specialty, academic rank, and years of experience. Main Outcomes and Measures: Surgeon perspectives on external barriers and facilitators of clinical practice development and strategies to support practice development for new academic surgeons. Results: A total of 45 surgeons were interviewed (23 women [51%], 18 with ≤5 years of experience [40%], and 20 with ≥10 years of experience [44%]). Surgeons reported barriers and facilitators related to their colleagues, department, institution, and environment. Dominant themes for both genders were related to competition, case distribution among partners, resource allocation, and geographic market saturation. Women surgeons reported additional challenges related to gender-based discrimination (exclusion, questioning of expertise, role misidentification, salary disparities, and unequal resource allocation) and additional demands (related to appearance, self-advocacy, and nonoperative patient care). Gender concordance with patients and referring physicians was a facilitator of practice development for women. Surgeons suggested several strategies for their colleagues, department, and institution to improve practice development by amplifying facilitators and promoting objectivity and transparency in resource allocation and referrals. Conclusions and Relevance: The findings of this qualitative study suggest that a surgeon's external context has a substantial influence on their practice development. Academic institutions and departments of surgery may consider the influence of their structures and policies on early career surgeons to accelerate practice development and workplace equity.

Perceived Implications of Compensation Structure for Academic Surgical Practice: A Qualitative Study.

This qualitative study examines how incentive-based and salary-only compensation models affect academic surgeons.

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.

Predictive Risk Score for Postparathyroidectomy Hungry Bone Syndrome in Patients With Secondary Hyperparathyroidism.

PURPOSE: Secondary hyperparathyroidism (SHPT) frequently affects patients with end-stage renal disease. Hungry bone syndrome (HBS) is a common complication among patients who undergo parathyroidectomy for SHPT and may cause prolonged hospitalization or require intensive care. The objective of this study is to develop a scoring system to stratify patients according to their risk of developing HBS. METHODS: A retrospective cohort study was performed using the US Renal Data System (2010-2021). Univariable and multivariable logistic regression models were developed and weighted ß-coefficients from the multivariable model were used to construct a risk score for the development of HBS. Positive and negative predictive values were assessed. RESULTS: Of 17 074 patients who underwent parathyroidectomy for SHPT, 19.4% developed HBS. Intensive care unit admission was more common in patients who developed HBS (33.5% vs 24.6%, P < .001). On multivariable logistic regression analysis, younger age, renal osteodystrophy, longer duration of dialysis, longer duration of kidney transplant, and higher Elixhauser score were significantly associated with HBS. A risk score based on these clinical factors was developed, with a total of 6 possible points. Rates of HBS ranged from 8% in patients with 0 points to 44% in patients with 6 points. The risk score had a poor positive predictive value (20.3%) but excellent negative predictive value (89.3%) for HBS. CONCLUSION: We developed a weighted risk score that effectively stratifies patients by risk for developing HBS after parathyroidectomy. This tool can be used to counsel patients and to identify patients who may not require postoperative hospitalization.

Assessing the Frequency of Deferrable Thyroid Nodule Biopsies to De-escalate Low-Value Care.

OBJECTIVE: Thyroid nodules are common, yet fewer than 1 in 10 harbors malignancy. When present, thyroid cancer is typically indolent with excellent survival. Therefore, patients who are not candidates for thyroid cancer treatment due to comorbid disease may not require further thyroid nodule evaluation. The goal of this study was to determine the rate of deferrable thyroid nodule biopsies in patients with limited life expectancy. METHODS: We identified patients who underwent thyroid fine needle aspiration (FNA) between 2015 and 2018 at our institution. The primary outcome was the number of deferrable FNAs, defined as FNAs performed in patients who died within 2 years after biopsy. Secondary outcomes included cytologic Bethesda score, procedure costs, and final diagnosis on surgical pathology. Multivariable logistic and Cox proportional hazards regressions were used to evaluate factors associated with FNA in patients with limited life expectancy. RESULTS: A total of 2565 FNAs were performed. Most patients were female (79%), and 37 (1.5%) patients died within 2 years. Nonthyroid specialists were significantly more likely to order deferrable FNAs (odds ratio 4.13, P < .001). Of the patients who died within 2 years, most (78%) had a concomitant diagnosis of nonthyroid cancer, and 4 went on to have thyroid surgery (Bethesda scores: 3, 4, 4, and 6). Spending associated with deferrable FNAs and subsequent surgery totaled over $98 000. CONCLUSIONS: Overall, the rate of deferrable thyroid nodule biopsies was low. However, there is an opportunity to reduce low-value biopsies in patients with a concurrent nonthyroid cancer by partnering with oncology providers.

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.

The effect of Section 1557 of the Affordable Care Act on surgical outcomes in non-English primary language speakers.

BACKGROUND: In 2016, Section 1557 mandated use of qualified language interpreter services. We examined the effect of Section 1557 on surgical outcomes. METHODS: Utilizing the Healthcare Cost and Utilization Project State Inpatient Database (2013-2020), we performed a difference-in-differences analysis of adult surgical patients (Maryland, New Jersey). The exposure was implementation of Section 1557 (pre-period: 2013-2015; post-period: 2017-2020). The treatment group was non-English primary language speakers (n-EPL). The comparison group was English primary language speakers (EPL). Outcomes included length-of-stay, postoperative complications, mortality, discharge disposition, and readmissions. RESULTS: Among 2,298,584 patients, 198,385 (8.6%) were n-EPL. After implementation of Section 1557, n-EPL saw no difference in readmission rates but did experience significantly higher rates of mortality (+0.43%, p â€‹= â€‹0.049) and non-routine discharges (+1.81%, p â€‹= â€‹0.031) in Maryland, and higher rates of post-operative complications (+0.31%, p â€‹= â€‹0.001) in both states, compared to pre-Section 1557. CONCLUSIONS: Contrary to our hypothesis, Section 1557 did not improve surgical outcomes for n-EPL.

The use and costs of same-day surgery versus overnight admission for total thyroidectomy: A multi-state, all-payer analysis.

BACKGROUND: Outpatient thyroidectomy is increasingly favored, given evidence of safety and convenience for selected patients. However, the prevalence of same-day discharge is unclear. We aimed to evaluate temporal trends, hospital characteristics, and costs associated with same-day discharge after total thyroidectomy in an all-payer, multi-state cohort. METHODS: We included patients aged ≥18 years who underwent a total thyroidectomy (2013-2019) using Healthcare Cost and Utilization Project data. Admission type was defined as same-day, overnight, or inpatient based on length of stay. Same-day patients were propensity-score matched 1:1 with overnight patients. Hospital characteristics and costs were compared in the matched cohort. RESULTS: Among 86,187 patients who underwent total thyroidectomy, 16,743 (19.4%) cases were same-day, 59,778 (69.4%) were overnight, and 9,666 (11.2%) were inpatient. The proportion of patients who underwent same-day thyroidectomy increased from 14.8% to 20.8% over the study period (P < .001), whereas overnight admissions decreased from 72.9% to 68.8% (P < .001). In total, 9,571 same-day patients were matched to 9,571 overnight patients. Same-day patients had higher odds of treatment at a certified cancer center (odds ratio 1.77; 95% confidence interval 1.65-1.90), Accreditation Council for Graduate Medical Education-accredited teaching hospital (odds ratio 1.72; 95% confidence interval 1.61-1.85), and high-volume hospital (odds ratio 1.53; 95% confidence interval 1.42-1.65). Pairwise cost differences showed median savings of $974 (interquartile range -1,610 to 3,491) for same-day relative to overnight admission (P < .001). CONCLUSION: Although over two-thirds of patients are admitted overnight, same-day total thyroidectomy is increasingly performed. Same-day thyroidectomy may be a lower-cost option for selected patients, particularly in specialty centers with experience in thyroidectomy.

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.

Mortality Among Older Medical Patients at Flagship Hospitals and Their Affiliates.

BACKGROUND: We define a "flagship hospital" as the largest academic hospital within a hospital referral region and a "flagship system" as a system that contains a flagship hospital and its affiliates. It is not known if patients admitted to an affiliate hospital, and not to its main flagship hospital, have better outcomes than those admitted to a hospital outside the flagship system but within the same hospital referral region. OBJECTIVE: To compare mortality at flagship hospitals and their affiliates to matched control patients not in the flagship system but within the same hospital referral region. DESIGN: A matched cohort study PARTICIPANTS: The study used hospitalizations for common medical conditions between 2018-2019 among older patients age ≥ 66 years. We analyzed 118,321 matched pairs of Medicare patients admitted with pneumonia (N=57,775), heart failure (N=42,531), or acute myocardial infarction (N=18,015) in 35 flagship hospitals, 124 affiliates, and 793 control hospitals. MAIN MEASURES: 30-day (primary) and 90-day (secondary) all-cause mortality. KEY RESULTS: 30-day mortality was lower among patients in flagship systems versus control hospitals that are not part of the flagship system but within the same hospital referral region (difference= -0.62%, 95% CI [-0.88%, -0.37%], P<0.001). This difference was smaller in affiliates versus controls (-0.43%, [-0.75%, -0.11%], P=0.008) than in flagship hospitals versus controls (-1.02%, [-1.46%, -0.58%], P<0.001; difference-in-difference -0.59%, [-1.13%, -0.05%], P=0.033). Similar results were found for 90-day mortality. LIMITATIONS: The study used claims-based data. CONCLUSIONS: In aggregate, within a hospital referral region, patients treated at the flagship hospital, at affiliates of the flagship hospital, and in the flagship system as a whole, all had lower mortality rates than matched controls outside the flagship system. However, the mortality advantage was larger for flagship hospitals than for their affiliates.

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.
