[PMID: 38194046 PMCID: PMC10997543 DOI: 10.1245/s10434-023-14852-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 12/17/2023] [Indexed: 01/10/2024]
Abstract
INTRODUCTION We sought to define the individual contributions of patient characteristics (PCs), hospital characteristics (HCs), case volume (CV), and social determinants of health (SDoH) on in-hospital mortality (IHM) after complex cancer surgery. METHODS The California Department of Health Care Access and Information database identified patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PD), or proctectomy (PR) for a malignant diagnosis between 2010 and 2020. Multi-level multivariable regression was performed to assess the proportion of variance explained by PCs, HCs, CV and SDoH on IHM. RESULTS A total of 52,838 patients underwent cancer surgery (ES: n = 2,700, 5.1%; PN: n = 30,822, 58.3%; PD: n = 7530, 14.3%; PR: n = 11,786, 22.3%) across 294 hospitals. The IHM for the overall cohort was 1.7% and varied from 4.4% for ES to 0.8% for PR. On multivariable regression, PCs contributed the most to the variance in IHM (overall: 32.0%; ES: 21.6%; PN: 28.0%; PD: 20.3%; PR: 39.9%). Among the overall cohort, CV contributed 2.4%, HCs contributed 1.3%, and SDoH contributed 1.2% to the variation in IHM. CV was the second highest contributor to IHM among ES (5.3%), PN (5.3%), and PD (5.9%); however, HCs were a more important contributor among patients who underwent PR (8.0%). The unexplained variance in IHM was highest among ES (72.4%), followed by the PD (67.5%) and PN (64.6%) patient groups. CONCLUSIONS PCs are the greatest underlying contributor to variations in IHM following cancer surgery. These data highlight the need to focus on optimizing patients and exploring unexplained sources of IHM to improve quality of surgical care.

[PMID: 38634960 DOI: 10.1245/s10434-024-15278-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 03/25/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND The association of hospital market competition, financial costs, and quality of oncologic care has not been well-defined. This study sought to evaluate variations in patient outcomes and financial expenditures after complex cancer surgery across high- and low-competition markets. METHODS Medicare 100% Standard Analytic Files were used to identify patients with lung, esophageal, gastric, hepatopancreaticobiliary, or colorectal cancer who underwent surgical resection between 2018 and 2021. Data were merged with the annual hospital survey database, and the hospital market Herfindahl-Hirschman index was used to categorize hospitals into low- and high-concentration markets. Multi-level, multivariable regression models adjusting for patient characteristics (i.e., age, sex, comorbidities, and social vulnerability), year of procedure, and hospital factors (i.e., case volume, nurse-bed ratio, and teaching status) were used to assess the association between hospital market competition and outcomes. RESULTS Among 117,641 beneficiaries who underwent complex oncologic surgery, the mean age was 73.8 ± 6.1 years, and approximately one-half of the cohort was male (n = 56,243, 47.8%). Overall, 63.8% (n = 75,041) of the patients underwent care within a high-competition market. Notably, there was marked geographic variation relative to market competition. High versus low market-competition hospitals were more likely to be in high social vulnerability areas (35.1 vs 27.5%; p < 0.001), as well as care for racial/ethnic minority individuals (13.8 vs 7.7%; p < 0.001), and patients with more comorbidities (≥ 2 Elixhauser comorbidities: 63.1 vs 61.1%; p < 0.001). In the multivariable analysis, treatment at hospitals in high- versus low-competition markets was associated with lower odds of achieving a textbook outcome (odds ratio, 0.95; 95% confidence interval, 0.91-0.99; p = 0.009). Patients at high-competition hospitals had greater mean index hospitalization costs ($19,462.2 [16211.9] vs $18,844.7 [14994.7]) and 90-day post-discharge costs ($7807.8 [15431.3] vs $7332.8 [14038.2]) (both p < 0.001) than individuals at low-competition hospitals. CONCLUSIONS Hospital market competition was associated with poor achievement of an optimal postoperative outcome and greater hospitalization costs.

Association of Racial and Economic Privilege on Postoperative Outcomes Among Medicare Beneficiaries. J Surg Res 2024; 296:37-46. [PMID: 38215675 DOI: 10.1016/j.jss.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Revised: 11/15/2023] [Accepted: 12/17/2023] [Indexed: 01/14/2024]
Abstract
INTRODUCTION Social determinants of health can play an important role in patient health. Privilege is a right, benefit, advantage, or opportunity that can positively affect all social determinants of health. We sought to assess variations in the prevalence of privilege among patient populations and define the association of privilege on postoperative surgical outcomes. METHODS Medicare beneficiaries who underwent elective coronary artery bypass grafting, abdominal aortic aneurysm repair, total hip arthroplasty, total knee arthroplasty, colectomy, and lung resection were identified. The Index of Concentration of Extremes (ICE), a validated metric of both social spatial polarization and privilege was calculated and merged with county-level data obtained from the American Community Survey. Textbook outcome (TO) was defined as absence of postoperative complications, extended length of stay, 90-day mortality, and 90-day readmission. Multivariable regression analysis was performed to assess the relationship between ICE and TO. RESULTS Among 1,885,889 Medicare beneficiaries who met inclusion criteria, 655,980 (34.8%) individuals resided in areas with the highest privilege (i.e., White, high-income homogeneity), whereas 221,314 (11.7%) individuals resided in areas of the lowest privilege (i.e., Black, low-income homogeneity). The overall incidence of TO was 66.2% (n = 1,247,558). On multivariable regression, residence in the most advantaged neighbourhoods was associated with a lower chance of surgical complications (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.88-0.91), a prolonged length of stay (OR 0.81, 95% CI 0.79-82), 90-day readmission (OR 0.94, 95% CI 0.92-0.95), and 90-day mortality (OR 0.71, 95% CI 0.68-0.74) (all P < 0.001). Residence in the most privileged areas was associated with 19% increased odds of achieving TO (OR 1.19, 95% CI 1.18-1.21), as well as a 6% reduction in Medicare expenditures versus individuals in the least privileged counties (OR 0.94, 95% CI 0.94-0.94) (both P < 0.001). CONCLUSIONS Privilege, based on the ICE joint measure of racial/ethnic and economic spatial concentration, was strongly associated with the likelihood to achieve an "optimal" TO following surgery. As healthcare is a basic human right, privilege should not be associated with disparities in surgical care.

Association Between Historical Redlining and Access to High-Volume Hospitals Among Patients Undergoing Complex Cancer Surgery in California. Ann Surg Oncol 2024; 31:1477-1487. [PMID: 38082168 DOI: 10.1245/s10434-023-14679-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Accepted: 11/13/2023] [Indexed: 02/08/2024]
Abstract
BACKGROUND We sought to determine the impact of historical redlining on travel patterns and utilization of high-volume hospitals (HVHs) among patients undergoing complex cancer operations. METHODS The California Department of Health Care Access and Information database was utilized to identify patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PA), or proctectomy (PR) for cancer between 2010 and 2020. Patient ZIP codes were assigned Home Owners' Loan Corporation grades (A: 'Best'; B: 'Still Desirable'; C: 'Definitely Declining'; and D: 'Hazardous/Redlined'). A clustered multivariable regression was used to assess the likelihood of patients undergoing surgery at an HVH, bypassing the nearest HVH, and total real driving time and travel distance. RESULTS Among 14,944 patients undergoing high-risk cancer surgery (ES: 4.7%, n = 1216; PN: 57.8%, n = 8643; PD: 14.4%, n = 2154; PR: 23.1%, n = 3452), 782 (5.2%) individuals resided in the 'Best', whereas 3393 (22.7%) individuals resided in redlined areas. Median travel distance was 7.8 miles (interquartile range [IQR] 4.1-14.4) and travel time was 16.1 min (IQR 10.7-25.8). Overall, 10,763 (ES: 17.4%; PN: 76.0%; PA: 63.5%; PR: 78.4%) patients underwent surgery at an HVH. On multivariable regression, patients residing in redlined areas were less likely to undergo surgery at an HVH (odds ratio [OR] 0.67, 95% confidence interval [CI] 0.54-0.82) and were more likely to bypass the nearest hospital (OR 1.80, 95% CI 1.44-2.46). Notably, Medicaid insurance, minority status, limited English-language proficiency, and educational level mediated the disparities in access to HVH. CONCLUSION Surgical disparities in access to HVH among patients from historically redlined areas are largely mediated by social determinants such as insurance and minority status.

Abstract
BACKGROUND Malnutrition has been linked to the development of hepatopancreatobiliary (HPB) cancer. We sought to examine the association between food swamps and food deserts on surgical outcomes of patients with HPB cancer. METHODS Patients who underwent surgery for HPB cancer between 2014 and 2020 were identified from the Medicare Standard Analytic Files. Patient-level data were linked to the United States Department of Agriculture data on food swamps and deserts. Multivariable regression was performed to examine the association between the food environment and outcomes. RESULTS Among 53,426 patients, patients from the worse food environment were more likely to be Black, have a higher Charlson Comorbidity Index, and reside in areas with high social vulnerability. Following surgery, the overall incidence of textbook outcome (TO) was 41.6% (n = 22,220). Patients residing in the worse food environments less often achieved a TO versus individuals residing in the healthiest food environments (food swamp: 39.4% vs. 43.9%; food desert: 38.5% vs 42.2%; p < 0.05). On multivariable analysis, individuals residing in the poorest food environments were associated with lower odds of achieving TO compared with individuals living in healthiest food environments (food swamp: OR 0.83, 95%CI 0.75-0.92, food desert: OR 0.86, 95%CI 0.76-0.97; both p < 0.05). CONCLUSION The surrounding food environment of patients may serve as a modifiable socio-demographic risk factor that contributes to disparities in surgical outcomes of HPB cancer.

Association of Textbook Outcome and Hospital Volume with Long-Term Survival Following Resection for Hepatocellular Carcinoma: What Matters More? J Gastrointest Surg 2023; 27:2763-2770. [PMID: 37940807 DOI: 10.1007/s11605-023-05880-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Accepted: 10/28/2023] [Indexed: 11/10/2023]
Abstract
BACKGROUND Both textbook outcome (TO) and hospital volume have been identified as quality metrics following cancer surgery. We sought to examine whether TO or hospital volume is more important relative to long-term survival following surgical resection of hepatocellular carcinoma (HCC). METHODS Patients who underwent surgery for HCC between 2004 and 2018 were identified using the National Cancer Database. TO was defined as R0 margin resection, no extended length of stay, no 30-day readmissions, and no 90-day mortality. The impact of TO and hospital case volume on long-term survival was determined using multivariable Cox regression. RESULTS Among 24,895 patients who underwent HCC resection, 9.0% (n = 2,252), 79.5% (n = 19,787), and 11.5% (n = 2,856) of patients were operated on at low-, medium-, and high-volume hospitals, respectively. Treatment at high-volume hospitals and achievement of a post-operative TO were independently associated with improved 5-year overall survival (OS). Pairwise comparison demonstrated that patients treated at high-volume hospitals who did not achieve a TO still had a better 5-year OS versus individuals treated at low-volume hospitals who did achieve a TO (5-year OS, no TO vs. TO: low-volume hospitals, 26.5% vs. 48.6%; high volume hospitals: 62.6% vs. 74.9%, respectively; p < 0.001). Overall, resection of HCC at a high-volume hospital was independently associated with a 54% reduction in mortality. CONCLUSION Long-term survival following HCC resection was largely associated with hospital case volume rather than TO. The effect of TO on long-term outcomes was largely mediated by hospital case volume highlighting the importance of centralization of care for patients with HCC.
