Introduction

Case-control studies are a powerful epidemiological method for identifying risk factors for disease. They are generally complex to design and execute. However, the difficulties of conducting such studies have been substantially increased by concerns about confidentiality and access to medical records. These barriers could be deleterious to the public's health. In this article, we report some of the problems we faced in conducting a national case-control study of Creutzfeldt-Jakob disease.

Data protection in the United Kingdom

Advances in computer technology have given rise to fears about access to patients' records. The UK response was to supplement doctors' common law duty of confidentiality to their patients with the Data Protection Act 1998. Much debate has ensued about the extent to which medical research could be impeded, including issues surrounding informed consent, patient confidentiality, anonymisation, and access to data.1 2 The subsequent updating of guidance on confidentiality by various professional organisations has produced inconsistencies, adding to the confusion about . . .
