Evaluation of a Decision Aid for Adult Cystic Fibrosis Patients Considering Bilateral Lung Transplantation
In 2006, the International Patient Decision Aids Collaboration (IPDAS) reached agreement on criteria for evaluation. Accordingly, the primary outcome is 'decision quality' 3 weeks after using the decision aid. Decision quality is defined as the extent to which a patient decision aid improves the match between the chosen option and the features that matter most to the informed patient. Measures include: a) patients' knowledge of essential facts [options, benefits, harms, and outcome probabilities]; and b. the congruence between the option chosen and patients' informed values regarding benefits and risks.
In the past twenty years lung transplantation has become the most widely accepted option of treating cystic fibrosis patients with severe lung disease. Lung transplantation can be a good experience for many patients, improving their quality of life and their survival. However there are potential risks of lung transplantation including infection, organ rejection and early death. Cystic fibrosis patients are often faced with making a choice of whether to be referred for lung transplantation when they are very sick and there is the immediate need to survive. Our group has developed a tool called a decision aid which we hope will assist the patient and family in making this choice. The decision aid guides the patient through a series of steps where they weigh the benefits and risks of being referred for lung transplantation and the benefits and risks of receiving 'usual care' without the option of referral.
