Characteristics of dentists participating in capitation and Preferred Provider Organization dental plans.
BACKGROUND
In 1998, the American Dental Association Survey Center conducted a telephone and mail survey of U.S. dentists in private practice in an effort to determine the extent of dentists' participation in capitation and preferred provider organization, or PPO, dental plans and the characteristics of dentists who participate in those plans.


METHODS
An initial telephone screening survey of a random sample of 11,550 dentists in private practice was conducted to identify dentists who participated in PPO or capitation dental plans. Dentists who participated in either of these plan types then were asked to complete a mail survey on their plan participation.


RESULTS
The majority of dentists participating in either type of dental plan reported having never left a dental plan. Dentists who belonged to more than one PPO or capitation plan reported that a larger percentage of their patients were enrolled in these plans and that more of their practice's gross income came from the plans. Participation in PPO and capitation plans has had a positive impact on the practices of many of the responding dentists, particularly with regard to expanding their patient base.


CONCLUSIONS
The authors found that the majority of dentists participating in PPO dental plans found it to be a positive experience overall. Dentists participating in capitation plans were less satisfied; more than 50 percent of capitation plan participants reported some level of dissatisfaction with the plans. The majority of dentists participating in a PPO plan expected to renew participation when their current contract expired; a much smaller percentage (though still a majority) of responding capitation-plan participants indicated the same.


CONCLUSIONS
Responding dentists' overall indication of satisfaction with their current PPO plan participation probably indicates further growth for these dental plans. On the other hand, capitation plan participants seem much less satisfied with their plans. PPO plans, therefore, seem much more likely to be the type of plan that dentists will choose in the future.
