Epidemiologic trends and costs of fragmentation.

The data that were reviewed in this article documented that in health systems, which manage behavioral health disorders independently from general medical disorders, the estimated 10% to 30% of patients with behavioral health service needs can expect (1) poor access or barriers to medical or mental health care; (2) when services are available, most provided will not meet minimum standards for expected outcome change; and (3) as a consequence of (1) and (2), medical and behavioral disorders will be more persistent with increased complications, will be associated with greater disability, and will lead to higher total health care and disability costs than will treatment of patients who do not have behavioral health disorders. This article proposes that these health system deficiencies will persist unless behavioral health services become an integral part of medical care (ie, integrated). By doing so, it creates a win-win situation for virtually all parties involved.
