Factors affecting physicians' choice to practice in a fee-for-service setting versus an individual practice association.

Individual Practice Associations (IPAs) must be able to recruit physicians from the community to compete in the future. This article reports the results of a study to assess the factors that influenced physicians in the Research Triangle area of North Carolina to join a primary care network type of IPA. Results indicate that physicians with lower incomes and fewer physician visits and those who were newly established in the community were more likely to join. Peers had a strong influence on their decisions, while Blue Cross/Blue Shield marketing representatives did not.
