Mode of payment as a predictor of health status, use of health services and preventive health behavior: a report from the Los Angeles Health Survey.
Several issues relevant to Health Maintenance Organizations (HMOs) were examined in this article using data collected from the Los Angeles Health Survey. No support was found for the hypothesis that HMOs disproportionately attract people in poorer health. In fact, HMO members actually reported lower rates of acute or occasional illness and disability than fee-for-service subscribers (FFS). HMO members also reported lower total family incomes and educational status than FFS subscribers and they were less likely to report having a regular doctor. Few differences were found between the two groups in reports of using health services and practicing preventive health behavior. However, HMO members were more likely to report a recent physical examination--but only after taking into account the fact that they were less likely to have a regular doctor. It has been shown that these findings are consistent with recent evidence, and serve to amplify serveral key findings reported in other studies.
