Implementation of workplace-based assessment in general practice.

: Workplace-based assessment (WPBA) is widely accepted, but few studies have investigated implementation issues during general practice (GP) placements. This study explored possible barriers and identified key elements for successful implementation of a WPBA-programme in Danish GP specialist training. : Supervisors had attended a one-day course in WPBA and trainees had received a short introduction. Questionnaires on experiences with implementation of WPBA were distributed to 106 GP supervisors and 110 trainees after the rotation was finished. : The response rate was 61/96 (64%) for trainees and 67/94 (71%) for supervisors. Supervisors were generally more positive towards WPBA and saw fewer barriers than trainees. Lack of planning was most often reported as an impediment to WPBA. Supervisors did not identify trainees' uneasiness of being observed as a problem as often as trainees. A total of 34% of trainees reported uneasiness as an obstacle to WPBA. : It seems that the education of supervisors positively influenced supervisors' perception and use of WPBA. Adequate planning of WPBA may be just as big a problem as assigning the time. Further investigations on the impact of education on trainees' perception of WPBA are needed.
