An urn model of Pólya-Eggenberger type is applied to the problem of measuring provider continuity in ambulatory care. The model is fitted to data from a Swedish community health care center, and predictions from the model are compared with observed counts from patients visit data. Two well known continuity of care measures, the COC and SECON indices, are shown to have a simple interpretation in terms of the model parameters, and their accuracy is discussed in the light of the urn model. Two further indices suggested in medical care literature are briefly discussed.
一个波利亚 - 埃根伯格类型的瓮模型被应用于测量门诊医疗中医疗服务提供者连续性的问题。该模型被拟合到瑞典社区医疗中心的数据上，并将模型的预测结果与患者就诊数据的观察计数进行比较。两种著名的医疗连续性测量指标，即COC和SECON指数，在模型参数方面具有简单的解释，并根据瓮模型讨论了它们的准确性。还简要讨论了医疗文献中提出的另外两个指数。
