Knowledge of the size of a practice population is an essential base for the evaluation of new forms of health care delivery and for epidemiologic research in primary care. Remuneration to providers in Ontario's Health Service Organization and Health Centre programs is partially based on the number of people listed on the patient roster as members of the practice. However, the accuracy of these rosters has never been determined. A mail and telephone survey was conducted to validate the roster in one such health center. A random sample of 1,065 households was contacted and a 78 percent response rate was obtained. The practice roster showed a population of 3,134. The age- and sex-adjusted estimate from the survey was 2,964 (+/- 262) individuals. The sensitivity, specificity, and accuracy of the roster were 0.90 or greater. It is concluded that this particular roster is a valid indicator of practice size, but caution is expressed about generalizing these results to other practices.
了解执业人群的规模是评估新型医疗服务提供形式以及开展初级保健流行病学研究的重要基础。安大略省卫生服务组织和健康中心项目向医疗服务提供者支付的薪酬部分基于患者名单上登记为执业成员的人数。然而，这些名单的准确性从未得到确定。在一个这样的健康中心进行了一项邮寄和电话调查，以验证名单。联系了1065户家庭的随机样本，获得了78%的回复率。执业名单显示人口为3134人。调查中年龄和性别调整后的估计数为2964人（±262人）。名单的敏感性、特异性和准确性均为0.90或更高。得出的结论是，这份特定的名单是执业规模的有效指标，但对将这些结果推广到其他执业情况表示谨慎。
