Racial Disparities in Health Service Utilization Among Medicare Fee-for-Service Beneficiaries Adjusting for Multiple...

To examine racial disparities in health services utilization in Hawaii among Medicare fee-for-service beneficiaries aged 65 years and above.

All-cause utilization of inpatient, outpatient, emergency, home health agency, and skilled nursing facility admissions were investigated using 2012 Medicare data. For each type of service, multivariable logistic regression model was used to investigate racial disparities adjusting for sociodemographic factors and multiple chronic conditions.

Of the 84,212 beneficiaries, 27.8% were White, 27.4% were Asian, 27.3% were Pacific Islanders; 70.3% had two or more chronic conditions and 10.5% had six or more. Compared with Whites, all racial groups experienced underutilization across all types of services. As the number of chronic conditions increased, the utilization of inpatient, home health care, and skilled nursing facility dramatically increased.

Disparities persist among Asians and Pacific Islanders who encounter the problem of underutilization of various health services compared with Whites.
