Specially obtained data for night visiting fees show a considerable increase in the number of claims made per general practitioner and per 1000 patients. There were also considerable variations between the 116 executive councils: in 1973-4 the range was from 3-8 to 17-0 per 1000 patients. To explain these variations, their relations with the local characteristics of family practice and of the population was explored using regression analysis. The factors most strongly associated with variations in implied visiting rates were found to be deputising services and the proportion of social class V in the population.
专门获取的夜间出诊费用数据显示，每位全科医生和每千名患者提出的索赔数量有显著增加。116个执行委员会之间也存在很大差异：在1973 - 1974年期间，每千名患者的索赔范围从3 - 8到17 - 0不等。为了解释这些差异，我们使用回归分析探讨了它们与家庭医疗的当地特征以及人口特征之间的关系。结果发现，与隐含出诊率变化最密切相关的因素是代理服务以及社会阶层V在人口中的比例。
