In the era of managed care, agencies that provide mental health care c
an cope with the increasing volume of patients and the increasing seve
rity of their conditions by having a variety of mental health professi
onals provide services. A model for determining workforce needs for ou
tpatient mental health clinics is described, The model was used with w
orkload data from three Veterans Affairs clinics to determine that two
psychiatrists and five or six: nonpsychiatrists should be able to eva
luate 400 new patients a year and provide ongoing care for 2,300 patie
nts a year in such settings. The method can be adapted to determine wo
rkforce needs for other outpatient clinical settings.
