In an empirical study using data from a health center in Sweden, correlation coefficients were computed among nine different measures of continuity of care, five of them visit-based and four individual-based. Generally, the correlations were high. This may be due, in part, to the similar behavior of the measures for people making few visits. The correlations were also quite high, however, when the sample was restricted to people with many visits. Several measures display a significant dependence on utilization level. The results suggest that, for general purposes, the measure COC should be preferred among the individual-based measures and fraction-of-care continuity among the visit-based measures. On grounds of flexibility and ease of interpretation, the authors recommend fraction-of-care measures.
在一项利用瑞典一家健康中心数据进行的实证研究中，计算了九种不同的连续性护理措施之间的相关系数，其中五种基于就诊，四种基于个体。总体而言，相关性较高。这可能部分归因于就诊次数少的人群中这些措施的相似行为。然而，当样本仅限于就诊次数多的人群时，相关性也相当高。几种措施显示出对利用水平的显著依赖性。结果表明，一般而言，在基于个体的措施中应首选COC措施，在基于就诊的措施中应首选护理连续性比例措施。基于灵活性和易于解释的理由，作者推荐护理比例措施。
