Ten prepaid group health plans across the country were surveyed as part of an effort to estimate the need for dermatologists in the United States. Although generalizing the experiences of prepaid group practices to the general population is at best an imprecise approach, the dramatic shortage suggested by the data cannot be completely ascribed to the method used. Whereas the average ratio in the surveyed plans was 2.8 dermatologists per 100,00 subscribers, there are only about 1.9 dermatologists providing patient care per 100,000 persons in the general population. The difference between prepaid plan subscribers and the general population in annual visits to dermatologists is even more dramatic: 193 per 1,000 subscribers compared to 84 per 1,000 population.
作为评估美国皮肤科医生需求工作的一部分，对全国十个预付费团体健康保险计划进行了调查。尽管将预付费团体医疗实践的经验推广到普通人群充其量是一种不精确的方法，但数据所显示的严重短缺不能完全归因于所使用的方法。在接受调查的计划中，平均比例是每10万名订阅者有2.8名皮肤科医生，而在普通人群中，每10万人中只有约1.9名皮肤科医生提供患者护理。预付费计划订阅者和普通人群在每年看皮肤科医生的次数上的差异甚至更大：每1000名订阅者中有193次就诊，而每1000名普通人群中只有84次就诊。
