The authors reviewed all 228 competency evaluations performed at the Baltimore VA Medical Center during a 10-year period. Between 1980 and 1984 and 1985 and 1989, the rate of inpatients who had competency evaluations increased from 0.20% to 0.42%, and the average number of competency evaluations per year doubled from 12 to 24.6. The percentage of all psychiatric consultations which were for competency evaluation nearly doubled from 5% to 9.4%. The rate of competency evaluations was slightly but not significantly higher for patients over age 65 than the rate for younger patients (0.44% vs. 0.33%). However, older patients were significantly more likely to be judged incompetent.
作者回顾了巴尔的摩退伍军人事务医疗中心在10年期间进行的所有228次能力评估。在1980年至1984年以及1985年至1989年期间，接受能力评估的住院患者比例从0.20%增至0.42%，每年能力评估的平均次数从12次翻倍至24.6次。所有用于能力评估的精神科会诊的比例几乎翻倍，从5%增至9.4%。65岁以上患者的能力评估率略高于年轻患者，但差异无统计学意义（0.44%对0.33%）。然而，老年患者被判定无行为能力的可能性显著更高。
