The authors reviewed all 228 competency evaluations performed at the B
altimore VA Medical Center during a 10-year period. Between 1980 and 1
984 and 1985 and 1989, the rate of inpatients who had competency evalu
ations increased from 0.20% to 0.42%, and the average number of compet
ency evaluations per year doubled from 12 to 24.6. The percentage of a
ll psychiatric consultations which were for competency evaluation near
ly doubled, from 5% to 9.4%. The rate of competency evaluations was sl
ightly but not significantly higher for patients over age 65 than the
rate for younger patients (0.44% vs. 0.33%). However, older patients w
ere significantly more likely to be judged incompetent.
