Abstract

OBJECTIVE:

Higher hospital surgical volumes have been associated with lower complication rates following total-hip replacement. The objective of this study was to identify the characteristics of patients who undergo total-hip replacement at high-volume hospitals and their differences from those who receive care at low-volume hospitals.

METHODS:

Discharge data from patients undergoing total hip replacement in California from 1995 to 2005 were analyzed. Hospitals were classified into 3 tiers of low, intermediate, or high surgical volume. The relationships between race/ethnicity and income to utilization of low-volume and high-volume hospitals were examined by creating logistic regression models that include patient covariates such as age, gender, and comorbidity.

RESULTS:

This study analyzed 138399 cases of primary total-hip replacements during the study period. Patients of Hispanic ethnicity, or black or Asian race had higher relative risk ratios for being treated at a low-volume center compared to white patients.

CONCLUSIONS:

There are disparities in the characteristics of patients receiving care at hospitals performing a high volume or low volume of total-hip replacements. Hispanic ethnicity, and black and Asian race were statistically significant predictors of utilization of a low-volume hospital.
