Abstract: Potential excess use of health care services caused by insurance has been a major concern for almost every industrialized county. Moral hazard problems and fee-for-service payment methods are considered to be important factors for higher medical care utilization among those insured. Health care availability is another feature reportedly associated with health care use. Using the data from a National Health Interview Survey in Taiwan in 1990, this study examined differences in medical care utilization by beneficiaries under three major social insurance plans (i.e. Labor Insurance-LI, Government Employees' Insurance-GEI, and Farmers' Insurance-FI) which covered about half the population at that time. Logistic and Poisson regression models were applied to examine the effects of relevant factors on the probability and volume of physician visits. Results from the analyses revealed that (1) persons with different insurance plans had a similar higher probability of seeing a doctor than the uninsured, with the odds ratios ranged from 1.8 to 2.0. Also (2) the LI/FI participants consumed 60-73% more physician services than the uninsured, while the GEI enrollees utilized only 30% more physician services. Findings from our study concerning the access and use of physician services in different insurance plans provide some useful information for reforming a health care delivery system.
