abstract
Although guidelines for treating stage IV non‐small cell lung cancer suggest that the patient’s values should be considered in decision‐making, there are no practical tools available to assist them with their decision‐making.ObjectiveTo develop and evaluate a decision aid that incorporates patient values.Design and sample(1) Before/after evaluation with patients referred to a regional cancer centre. (2) Mailed survey of thoracic surgeons and respirologists in Ontario.InterventionAn audio‐tape guided individuals to review a booklet describing stage IV non‐small cell lung cancer, its impact and possible coping strategies, treatment options, benefits and risks, and examples of the decision‐making of others. Patients then used a worksheet to consider and communicate personal issues involved in the choice, including: personal values using a ‘weigh‐scale’; questions; preferred role in decision‐making; and predisposition.Measures(1) Patient questionnaires eliciting knowledge, the decision, decisional conflict and acceptability of the decision aid. (2) Physician questionnaires eliciting attitudes toward the decision aid.Results(1) Twenty of 30 patients used the aid in decision‐making. Users thought that the aid was acceptable and significantly improved their knowledge about options and outcomes (P < 0.001), and reduced their decisional conflict (P < 0.001). (2) The majority of the 29 physicians who reviewed the decision aid found it acceptable, were comfortable providing it to patients and said that they were likely to use it.ConclusionThe decision aid is a useful and acceptable adjunct to personal counselling.
