To investigate a method for obtaining immunisation information, and investigate the variation in immunisation coverage levels between practices.
The Wellington Area Health Board computer identified all children born in the first half of 1990 with a general practitioner in the Wellington district. The general practitioner provided the child's immunisation status, if still with the practice. The characteristics of the practice were tested for association with the immunisation coverage level.
The method identified approximately 80% of the target population. Most (97%) of the general practitioners agreed to provide immunisation information on the identified children. Immunisation information was obtained on 841 children, or about 65% of the total cohort. The percentage of the children fully immunised in each practice varied from 0% to 100%. An index of neediness of the children in the practice, was the only identified factor which explained variation between practices. Recall systems were neither necessary nor sufficient for obtaining high coverage in these practices.
The study method could form the basis of a system of gathering immunisation coverage information which assists general practitioners with immunisation recall.
研究获取免疫接种信息的方法，并调查各医疗机构之间免疫接种覆盖率的差异。
惠灵顿地区卫生局的计算机识别出1990年上半年在惠灵顿地区由全科医生接生的所有儿童。如果这些儿童仍在该医疗机构就诊，全科医生需提供其免疫接种状况。对医疗机构的特征进行检测，以确定其与免疫接种覆盖率之间的关联。
该方法识别出了约80%的目标人群。大多数（97%）全科医生同意提供所识别儿童的免疫接种信息。共获取了841名儿童的免疫接种信息，约占总队列的65%。各医疗机构中完全免疫接种儿童的比例从0%到100%不等。所识别出的唯一能解释各医疗机构之间差异的因素是该医疗机构中儿童的需求指数。在这些医疗机构中，召回系统对于实现高覆盖率既非必要也不充分。
该研究方法可为收集免疫接种覆盖率信息的系统奠定基础，有助于全科医生进行免疫接种召回。
