Distribution of resources according to need is an important component in the delivery of mental healthcare services. The measure of visit frequency provides information on cost and a rough measure of resource use. This research atlas examines changes from 1992/93 to 1997/98 in provider source (physicians who provide mental healthcare) and the visit frequency of mental healthcare users.
In the five-year period, usage patterns remained fairly constant, with 63% of mental healthcare users receiving care from a general practitioner or family physician, 22% seeing a psychiatrist and 12% seeing both. Most significantly, services were delivered to a larger percentage of Ontario’s population by providers seeing more patients rather than through an increase in the relative number of providers.
