This article deals mainly with the secondary use of medical records in research; primary use may have been for a clinical trial or for medical treatment. Well known examples of successful secondary use of data are discovery of the links between antidepressants and suicide and between tranquilisers and road accidents.1 2 These insights are important, even if they are not conclusive and may need to be confirmed by specific studies or trials.
Explicit consent is needed for all aspects of clinical trials, including the retention of medical records, either as identifiable data or in anonymised form.3 Consent is usually for that trial only (this can go to extremes; see box 1). Difficulties can arise over re-use of data, either for new questions that arise within the study, or for questions that could be considered once the data have been gathered but were not anticipated at the outset when consent was gained. In terms of efficiency and consistency of results, it is preferable to re-use data rather than re-collect it. Projects should therefore allow participants to choose at the outset whether data (and possibly tissues) can be retained for future research in a secure and confidential form.
The two main legal instruments are the Data Protection Act 1998 (DPA98) and the common law of confidence (confidentiality), which are discussed in another article in this series.4 Essentially, consent is needed to use personal data in medical research unless the person is dead; the researchers are all healthcare professionals or equivalent; or the data do not identify the person.
