Has access to care changed in minority communities? A study of preventable hospitalizations over time in selected...

This study assesses the changes in access to care in minority communities by examining the association between preventable hospitalization rates and racial/ethnic composition of the community during 1995-2005. Using hospital discharge data from Healthcare Cost and Utilization Project State Inpatient Database of the Agency for Healthcare Research and Quality in 5 states and focusing on the nonelderly adults and elderly age groups, the study includes a multivariate cross-sectional design using preventable hospitalization rates by primary care service area as the outcome and racial/ethnic compositions of total hospital discharges by resident population in the primary care service area as the primary explanatory variables. The study indicates increases in barriers faced by minority adults in accessing primary care over time, with no similar evidence for the elderly subgroup.
