Demand for general practitioner and internist services

D S Guzick

    Health Services Research

    Summary
    This summary is machine-generated.

    Healthcare seeking behavior differs between general practitioners and internists. As income or insurance coverage increases, patients may substitute internists for general practitioners, with lower price elasticity for internist services.

    Area of Science:

    • Health Economics
    • Medical Care Utilization
    • Econometrics

    Background:

    • Understanding the factors influencing patient choice between general practitioners and internists is crucial for healthcare resource allocation.
    • Previous research has not fully elucidated the distinct demand drivers for these two primary care specialties.

    Purpose of the Study:

    • To estimate demand equations for general practitioner and internist visits.
    • To identify differences in demand determinants and price elasticities between these two physician specialties.

    Main Methods:

    • Utilized 1970 CHAS-NORC survey data on health service utilization and expenditure.
    • Employed grouped regression analysis with group means due to a large proportion of zero visit observations.
    • Estimated demand equations for general practitioner and internist visits.

    Main Results:

    • Significant differences were found in the demand equations for general practitioner versus internist visits.
    • An apparent substitution effect was observed: internist use increased relative to general practitioner use with higher ability to pay (income/insurance).
    • Own-price elasticities were low for both, but lower for internists (0.02-0.1) than general practitioners (0.2-0.3).

    Conclusions:

    • Healthcare demand differs significantly between general practitioners and internists.
    • Increased ability to pay may lead patients to substitute internists for general practitioners.
    • Price sensitivity for internist services is notably lower than for general practitioners.
