Assessing the quality of an epidemiological study equates to assessing whether the inferences drawn from it are warranted when account is taken of the methods, the representativeness of the study sample, and the nature of the population from which it is drawn. Bias, confounding, and chance can threaten the quality of an epidemiological study at all its phases. Nevertheless, their presence does not necessarily imply that a study should be disregarded. The reader must first balance any of these threats or missing information with their potential impact on the conclusions of the report.

Challenges to clinical management are a fact of professional life. Every doctor must expect to become embroiled in complaints and claims from time to time and be prepared to justify why they managed a particular case in the way that they did. Good medical practice is defensible practice, which depends upon staying within the limits of your own expertise, keeping up to date and conducting audit, ensuring your administration is effective and that patients are not allowed to slip through the net, that you communicate effectively with patients, their carers and colleagues, and that medical records recall all salient facts relating to the patient. If things go wrong, be open, investigate the facts, explain the situation fully to the patient, and do not be afraid to apologise.
