Dear Linda, 

This paper is not really new but may help:

Prevalence, Severity, and Unmet Need for Treatment of Mental Disorders in the World Health Organization World Mental Health Surveys FREE

The WHO World Mental Health Survey Consortium

JAMA. 2004;291(21):2581-2590. doi:10.1001/jama.291.21.2581.

NextEra Energy Corporation (formerly FPL Group) has been integrating primary-care medicine with mental health services, nutrition services, fitness services, and health promotions for more than two decades.  The program manager, Andrew Scibelli, has gathered much data on the integration over the years including an exhaustive search for natural points-of-contact between those players and how those can be enhanced for better referrals, teamwork, communications, and shared resources.  He MAY have published some of that information, so you could search his name.  Here's a link to a general overview of the program:

Hello, Linda. A good reference I have found on integration is Alain C. Enthoven, PhD at the graduate school of business, Stanford University. His work focuses on the model of integrated service delivery at the primary levels to avoid fragmentation. Your question is an important one and the system of integration I believe is the important foundation element in ensuring that the service, mental health, or services are properly integrated with stakeholder and resource alignment. In other words, a coordinated and collaborative network that links providers across three areas, economic, noneconomic, and clinical (Enthoven, 2009).

Dear LInda,

Attached you'll find some of our work on somatic health in patients with severe mental illness and the cooperation between mental health and general practitioners.

Although it isn't new research, there is an interesting new report from the Blue Cross-Blue Shield Foundation in Massachusetts, USA.  It can be found at: http://bluecrossfoundation.org/publication/barriers-behavioral-and-physical-health-integration-massachusetts  and I am uploading it here.

The site states the following about the publication:

"The Blue Cross Blue Shield of Massachusetts Foundation is releasing a new report, Barriers to Behavioral and Physical Health Integration in Massachusetts. This report, prepared by Margaret Houy and Michael Bailit of Bailit Health Purchasing, LLC, provides a comprehensive review of the policy and regulatory barriers that impede behavioral health integration in Massachusetts and identifies potential options for addressing these barriers. This report is divided into three sections – licensing, privacy, and, reimbursement barriers – and was developed through a review of reports and other secondary sources, agency regulations and checklists, and interviews and a focus group with key stakeholders. Incorporating the input from the focus group, it concludes with a discussion of the top three priorities that, if addressed, would have the most significant impact on removing barriers to integration. This report is intended to serve as a resource summarizing key issues and potential opportunities for policymakers to improve the integration of physical and behavioral health care services."

Both of the authors are very experienced health services researchers and policy analysts.

Hello Linda, I hope this is useful to you. However, it is not recent. Best wishes!

After submitting my previous response, Linda, I thought of an interesting program that while not developed as research, per se, nonetheless has tracked its results.  It is about integration of child psychiatry support services with primary care services for children.  A description is attached; and the program remains active after many years now.
