The FHSA patient registration index was used as a sampling frame for a population questionnaire survey. The main survey of 3,359 was preceded by a pilot study of 250. Ethical issues such as anonymity and release of data were addressed in order to obtain the approval of the ethical committee and LMC. The acceptability to GPs and the public of using FHSA Registration data was tested. The validity of the survey was indicated by the proportion of wrong addresses, the response rate and the representativeness of the sample and responders. Appropriate software is needed for selecting a random sample and producing address labels.
FHSA患者登记索引被用作人口问卷调查的抽样框架。在对3359人进行主要调查之前，先对250人进行了试点研究。为了获得伦理委员会和地方医疗委员会（LMC）的批准，解决了诸如匿名性和数据发布等伦理问题。测试了全科医生（GPs）和公众对使用FHSA登记数据的接受程度。错误地址的比例、回复率以及样本和回复者的代表性表明了调查的有效性。选择随机样本和制作地址标签需要合适的软件。
