Much of the poor attendance stems from invited patients failing to attend. Aim: To design a theoretically based intervention to improve attendance at cardiac rehabilitation. Methods: Our methods followed recommendations that have been developed from the Medical Research Council (MRC) framework for the design of complex interventions. We conducted three processes that progressed simultaneously: 1) literature review for evidence on epidemiology, behavioural theory, and efficacy of interventions; 2) expert meetings on behavioural theory and to select target points for intervention; and 3) development and theoretical modelling of the intervention. Result: Our final interventions were a theoretically worded invitation letter and leaflet based on the Theory of Planned Behaviour and the Common Sense Model of Illness, designed to: a) motivate patients through professional recommendation; b) provide simple information on the contents of cardiac rehabilitation emphasising ease for participants; c) reassure participants that the programme is tailored to their personal needs in a safe supervised environment; and d) reinforce the benefits of attending cardiac rehabilitation. Conclusion: A theoretically worded letter and leaflet could be an inexpensive intervention to improve attendance at cardiac rehabilitation. The letters and leaflets will now be evaluated in a randomised trial. © 2009 European Society of Cardiology. Published by Elsevier B.V. All rights reserved.
