This edition of the journal includes, with an introduction and three commentaries, a recent joint statement from the British Medical Association, the Resuscitation Council (UK) and the Royal College of Nursing, on decisions relating to cardiopulmonary resuscitation (CPR).¹ The statement was produced in response both to a professional need to decide when attempting CPR is and is not ethically appropriate, or indeed lawful (especially in the light of incorporation of the European Convention on Human Rights into UK law), and also to public concern that such decisions have not always been made in concordance with the wishes of patients or people close to them. The guidelines it sets out reflect a broad consensus of current medicolegal views in the UK, include a variety of helpful and practical recommendations, and can be seen, in many respects, as a model of their kind. As a model of actual decision making however, they raise some problems. Model helps us understand the reality they represent by simplifying it, but in the process of simplification, aspects of the reality represented which do not fit in with the model may be left out or downplayed. Three such aspects identified by our commentators concern patient autonomy, quality of life judgments, and the role of families in decision making.
