The authors sought to develop and evaluate a training course on the theory and methods of seeking 'concordance' with patients who are using medications inappropriately. Eight general practitioners were recruited to a four-day interactive course including factual materials, attitudinal challenge, skills development and assessment. Participants enjoyed the course and thought they had learned from it. Knowledge and skills improved significantly and attitudes showed a non-significant shift. The study demonstrated that concordance-related skills can be taught and measured, suggesting that trials to assess the impact of such training on patient outcomes may be feasible and worthwhile.
