Summary
Hospital outpatient service demand is influenced by the availability and cost of alternative care, including office-based physicians and inpatient services. Insurance coverage also plays a role.
Area of Science:
- Health Services Research
- Health Economics
Background:
- Hospital outpatient services are a key component of medical care delivery.
- Understanding factors influencing their demand is crucial for healthcare planning and policy.
Purpose of the Study:
- To identify factors driving demand for hospital outpatient services.
- To analyze the relationship between outpatient service volume and alternative care options (office-based physicians, inpatient services).
Main Methods:
- Utilized a merged national dataset with population, socioeconomic, health services, manpower, and cost information.
- Replicated previous research using updated, geographically specific data (1978 Health Service Area data).
- Extended research by estimating demand equations, differentiating between emergency room and other outpatient visits.
Main Results:
- Confirmed and expanded upon previous findings regarding outpatient service demand.
- Demonstrated a relationship between outpatient service volume and the availability and price of alternative care sources.
- Identified insurance coverage as another significant influencing factor.
Conclusions:
- Findings have implications for reforming hospital outpatient reimbursement policies.
- Results can inform strategies for cost containment within Medicaid and related healthcare sectors.
- The study underscores the interconnectedness of various healthcare service delivery components.
