Improving mental and physical health outcomes in general healthcare settings: a Gedenkschrift in honor of Wayne Katon, MD (1950-2015).

This special article pays tribute to Wayne Katon, MD (1950-2015) with a Gedenkschrift, or review, of his prolific academic career. Abstracts of all of Dr. Katon's Medline citations were reviewed to develop a narrative of his seminal epidemiological and interventional research findings. Specifically, we describe: (a) how Dr. Katon's clinical work and observational epidemiology and health services research informed and guided interventional studies; (b) the evolution of multidisciplinary interventional trials from primary care-based psychiatric consultation to primary care-based collaborative care for depression to multicondition collaborative care; and (c) how Dr. Katon's research has informed the work of other leading researchers in the field of psychosomatic medicine and helped develop a new generation of researchers at the interface of psychiatry and primary care. For more than three decades, Dr. Katon led a multidisciplinary research team that conducted seminal epidemiological studies and randomized trials and that influenced the thinking and research in the field of psychiatry in a number of areas: (a) the importance and impact of mental disorders presenting in primary care settings and (b) the organization of effective multidisciplinary care for primary care patients with common mental disorders and comorbid medical conditions. Dr. Katon's work revolutionized the care of psychiatric illnesses in primary care and other medical care settings to the benefit of countless patients worldwide.
