Managed care for preventive services: a review of policy options.

In summary, the managed care system we propose for preventive services is designed to limit the potential for overcare under FFS payment and for undercare under capitation and comprehensive fixed fees. It bases payment on the provision of a complete set of preventive services, thus limiting the tendency of physicians to provide only the relatively high-profit services, such as screening tests, while neglecting the lower-profit services, such as counseling. It also allows primary care providers to outsource selected services to lower-cost providers, such as laboratories, health educators, and counselors, and community-based health promotion programs, thus encouraging greater efficiency. In addition, the proposed system funds both primary and high-risk preventive case management to ensure that individuals receive preventive services appropriate to their age, sex, and risk factors. Finally, the proposed system monitors the use of preventive services, relying on physician reminders to stimulate the appropriate provision of preventive care and denying payment for unauthorized care. Existing research suggests that none of the individual strategies for managed care can be expected to achieve all of the goals of managing and promoting the appropriate use of preventive services as defined by the U.S. Preventive Services Task Force (1989). To be most effective, we conclude that the strategies need to be coordinated and integrated into the current health care delivery practices of HMOs, PPOs, and point-of-service plans. In addition, the strategies require additional provider training in preventive care. With this support, the proposed model has the potential to improve quality, control costs, and increase the appropriate use of preventive care. While many of the individual components of the proposed managed care model have been evaluated for preventive services, a great deal more research is needed to evaluate the effect of combining these elements into a coordinated and comprehensive approach to managing preventive care. Research is also needed on workable ways to invite people not currently receiving medical care into the health care system to receive preventive care. To inform policy development, the impact of the proposed managed care model--both on preventive services utilization for specific screening, immunization, and counseling services, and on total health care costs and patient health status outcomes--needs to be evaluated.
