The author suggests that measuring utilization of benefits for nervous and mental disorders by using the percent of total benefits paid is imprecise because even small changes in the much larger portion of benefit payments that are attributable to nonpsychiatric services can make it appear that the level of psychiatric utilization has changed. His preferred measure is a calculation of covered charges attributable to psychiatric care per each person covered under the plan. The author illustrates his points by showing that, when properly calculated, psychiatric utilization under the Civilian Health and Medical Program of the Uniformed Services is much lower than that under many other plans.
作者认为，用支付的总福利百分比来衡量神经和精神障碍福利的利用率并不精确，因为在占比大得多的非精神科服务福利支付中，即使是很小的变化，也可能让人觉得精神科服务的利用率发生了变化。他更倾向的衡量方法是计算该计划下每个参保人可报销的精神科护理费用。作者通过举例说明，当计算正确时，统一服务部门的民用健康和医疗计划下的精神科服务利用率比许多其他计划要低得多。
