The author proposes a model of collaborative family-oriented health care and gives a brief history of its evolution and current status. The model rests upon the cooperation of health care providers from different disciplines-physicians, therapists, counselors, social workers, nurses-who provide more comprehensive care to patients and their families. Such care can be organized in a number of different ways, in different settings, and under different reimbursement schemes. Because it follows a broad biopsychosocial model of disease, it offers adherents of family systems medicine an opportunity to practice their skills in ways perhaps more consistent with their ideas than some existing models.The basic outlines of family systems medicine-its core theories, its perspective, its systemic and contextual insistence-have now been laid forth. The studies that validate its ideas have been accumulating for over 30 years, and while they might appear new in some circles, their overall coherence and strength is already a fait accompli. Yet something seems awry; the organization of health care which should reflect this systemic world view has not developed, and in fact lags behind the advances in theory. Far from being the swelling trend of the future, the collaborative model is now struggling for its life. Economic and political trends continue to reward the fragmentization and compartmentalization of health care, which is still provided along the lines of the old model: specialties and subspecialties; procedures, tests and operations.Almost all economic incentives in health care have been locked into biomedical modes of thinking about medical problems. The biomedical model of disease emphasizes pathological conditions, organ-system diseases, and disorders which appear caused by precise, known processes. It sticks narrowly to these confines. Today medicine has become a vast and complex money-making enterprise (16). Profits can be made and costs controlled mainly by fitting treatment into the traditional diagnostic categories. Relying upon diagnostic codes that are wedded to the biomedical model of disease, third party payers, in their effort to control costs, dictate the manner of payment for medical services and structure the way these services are conceptualized.
