Abstract

Background: Technical efficiency evaluates a hospital's economic performance and plays an important role in variations in quality of care and outcomes. The study objective was to examine the association between hospital efficiency and quality of care among fee-for-service Medicare beneficiaries with prostate cancer and to assess if race moderates this association.

Design: Retrospective study using Surveillance, Epidemiological, and End Results-Medicare (SEER-Medicare) data from 1998 to 2016 for prostate cancer patients aged ≥ 66. We computed hospital technical efficiency using a data envelopment analysis. Outcomes were emergency room visits, hospitalizations, cost, and mortality (all-cause and prostate cancer-specific). We used competing risk regression for survival, log-link GLM models for cost, and Poisson models for count data. The propensity score approach was used to minimize selection bias.

Results: The cohort consisted of 323,325 patients. Compared to higher efficiency hospitals (upper quartile), low hospital efficiency (i.e., lower quartile) was associated with a higher hazard of long-term mortality (Hazard ratio (HR) = 1.06, 95% CI = 1.05, 1.08) and long-term prostate cancer-specific mortality (HR = 1.14, 95% CI = 1.11, 1.17). Compared to higher efficiency levels, lower levels were associated with impaired emergency room visits, hospitalizations, and costs. A one unit increase in the efficiency score was associated with greater benefits for cost and mortality for African American and white patients. The benefit was larger for African American patients compared to white patients.

Conclusions: Increasing hospital efficiency may help improve outcomes among Medicare prostate cancer patients. Policies to redirect patients to hospitals with higher efficiency can enhance the quality of care and outcomes.

Keywords: health service use; hospital technical efficiency; mortality; prostate cancer; racial disparity.
