OBJECTIVE: To identify factors associated with utilization of low-volume hospitals for total hip replacement (THR) and to estimate differences in the distances that Medicare beneficiaries had to travel to reach low- or high-volume hospitals.
METHODS: We studied a population-based sample of 1,146 Medicare beneficiaries who underwent elective THR in 1995. Using multiple data sources including medical record review, Medicare claims data, 1990 Census data, and a patient survey, we examined factors independently associated with utilization of low-volume hospitals for elective THR. We estimated the magnitude of difference in distances for patients undergoing THR in low- and high-volume hospitals. We determined the distance between each patient's residence and the treating hospital using MapQuest.
RESULTS: Rural residency, low income, and low educational attainment, as well as belief in the importance of convenient location in the choice of hospital, were associated with higher utilization of low-volume hospitals. Rural and suburban patients who went to low-volume hospitals traveled much less than patients operated upon in high-volume centers.
CONCLUSION: Policies aimed at restricting THR to high-volume centers would differentially affect poor, less educated, and rural patients. Voluntary efforts to shift THR to high-volume centers should involve educating these patients and their referring physicians about differences in both short-term and longer-term outcomes between high- and low-volume centers.
