Health promotion and disease prevention in HMOs: a survey of newly established IPAs in New York City.

Independent Practice Associations (IPAs) are the fastest growing segment of the Health Maintenance Organization (HMO) industry, but little is known about their provision of health promotion and disease prevention to subscribers. To examine the extent to which IPA policies encourage health promotion and disease prevention, we interviewed medical directors and other senior administrators of six newly developing IPA-HMOs in New York City. We also reviewed promotional literature to assess how extensively health promotion and disease prevention were marketed to the potential subscriber. Although medical protocols for preventive screening exist in most IPAs, compliance with guidelines is left largely to the individual physician's judgment for implementation. IPA respondents suggested that their physician panels are oriented toward prevention, but there is uncertain evidence in this regard, and incentive payments could discourage referrals for screening. Health education programs are sporadic. Health promotion and disease prevention do not appear to be a high priority among six newly established IPAs in New York City. We recommend several steps that would encourage IPA-HMOs to increase their health promotion activities.
