This paper provides a description and analysis of the development, implementation, and continuing framework of practice for a model of comprehensive, coordinated maternal and child health programs in which traditional maternal and child health services are provided by a local county health department while family planning and related services are provided by a private non-profit agency. Clients' benefits of increased accessibility, continuity, and coordinated care are examined. It is noted that prenatal, child health, sexually transmitted disease, and nutrition services are integrated through formal and informal arrangements with the family planning provider. The paper discusses interstaff interaction, communication patterns, problem-resolution techniques, formal and informal linkage agreements, and cost efficiency. Included in the presentation are reactions from patients, staff, administration, and outside agencies routinely involved with both programs. The cumulative result of the model is a larger pool of cooperating health and allied professionals providing care and serving as resources for client and family. The cost efficient approach is shown to be a model for the community at large, demonstrating a potential for less fragmentation of the health care system to the consumer. The overall impact is the framework for larger community networking and the implementation of an effective client/family advocate system. (Author/NB)
