Value and face validity of objective structured assessment of technical skills (OSATS) for work based assessment of surgical skills in obstetrics and gynaecology

Background: Changes in UK Junior Doctor working patterns, reduced training hours and increased patient expectations have resulted in less exposure of Juniors to surgical procedures. Validated methods of assessment are therefore required to assure the surgical competency of future Consultants. Objective Structured Assessment of Technical Skills (OSATS) forms are one possible tool. Aims: To investigate trainee and trainer perceptions of the value and validity of OSATS in the operating theatre. Method: OSATS forms and feedback questionnaires. Results: 38 trainees and 16 trainers provided feedback on the OSATS forms used during 60 procedures, returning 119 questionnaires in total. Value : 85% of trainee and 76% of trainer responses agreed/strongly agreed that OSATS would improve trainees' surgical skills. Face validity: 80% of trainee and 76% of trainer responses agreed/strongly agreed with OSATS ability to assess surgical skills. Application: 76% of trainee and trainer responses agreed/strongly agreed that OSATS should become part of the annual assessment process for trainees. Conclusions: Trainees and trainers perceive OSATS to be a valuable and valid tool for the objective assessment of surgical skills in the work place. More research is required to assess their criterion-related, content, construct and predictive validity as well as their reliability in the workplace.
