Medicaid, morbidity, and physician use

Area of Science:

• Health Services Research
• Medical Economics
• Public Health Policy

Background:

• Medical programs for low-income, high-need individuals face scrutiny over costs and physician service utilization.
• Understanding healthcare access and utilization patterns across different socioeconomic groups is crucial for effective policy.

Purpose of the Study:

• To compare the utilization of physician and preventive healthcare services among Medicaid recipients and other income groups in the Baltimore SMSA.
• To investigate the factors influencing higher healthcare service use by Medicaid beneficiaries, controlling for morbidity.

Main Methods:

• Conducted a household interview survey in the Baltimore SMSA to collect data on health services utilization.
• Compared service use patterns between Medicaid recipients and two other income groups, adjusting for morbidity levels.

Main Results:

• Medicaid recipients exhibited the highest morbidity and consequently higher physician service utilization across all morbidity categories.
• Medicaid recipients were more likely to have physician-initiated visits, return appointments, and receive injections.
• Even among the 'healthy' subgroup, Medicaid recipients used more preventive services, indicating higher demand.

Conclusions:

• Higher healthcare service use by Medicaid recipients is primarily explained by their greater morbidity and increased need/demand for both curative and preventive services.
• Current constraints on physician services disproportionately impact the use of preventive care among low-income individuals not covered by Medicaid in the Baltimore SMSA.
