Professor Wayne Katon devoted much of his career to working out how outcomes could be improved for patients with depression seen in primary care. His answer, developed iteratively over a number of years, was ‘collaborative care’, the key element of which is a system of collaboration of a liaison psychiatrist with primary care doctors combined with monitoring of outcomes. This seminal development was first found to be effective in a trial published in 1995. Wayne subsequently worked with colleagues to deliver more trials of collaborative care including the large IMPACT trial for late life depression. He further developed collaborative care to provide integrated medical and psychiatric care, the value of which was established by the TEAM care trial published in 2010. This trial found that the integrated and active management of both medical (diabetes and heart disease) and psychiatric (major depression) disorders achieved not only better medical outcomes, but also a greater effect on depression than previous collaborative trials, showing the synergistic effect of integration. Collaborative care is now established as an effective approach to improving patient care internationally.
