Randomized Controlled Trial
What difference does training make? A randomized trial with waiting-list control of general practitioners seeking advanced training in drug misuse.
To measure changes in knowledge, attitudes and clinical practice of general practitioners (GPs) enrolled to receive training in the management of drug misusers. ⋯ GPs seeking special training for the care of drug misusers are both positively disposed to this patient population and clinically active. Benefits unambiguously attributable to the course were modest. While a TR effect was observed, strict adherence to ITT analysis failed to identify significant benefits observed with the training provided. Randomisation and waiting-list controls design are insufficient as a research method for training evaluation studies if ITT analysis is used exclusively.
