Composite reliability of workplace-based assessment of international medical graduates.

OBJECTIVE: The fitness to practise of international medical graduates (IMGs) is usually evaluated with standardised assessment tests. The performance rather than the competency of practising doctors should, however, be assessed, for which reason workplace-based assessment (WBA) has gained increasing attention. Our aim was to assess the composite reliability of WBA instruments for assessing IMGs. DESIGN AND SETTING: Between June 2010 and April 2015, 142 IMGs were assessed by 99 calibrated assessors; each was assessed in the workplace over 6 months. The IMGs completed 970 case-based discussions (CBDs), 1741 mini-clinical examination exercises (mini-CEX), and 1020 multi-source feedback (MSF) assessments. PARTICIPANTS: 103 male and 39 female candidates from 28 countries (Africa, Asia, Europe, South America, South Pacific) in urban and rural hospitals of the Hunter New England Health region. MAIN OUTCOME MEASURES: The composite reliability across the three WBA tools, expressed as the standard error of measurement (SEM). RESULTS: In our WBA program, a combination of five CBD and 12 mini-CEX assessments achieved an SEM of 0.33, greater than the threshold 0.26 of a scale point. Adding six MSF results to the assessment package reduced the SEM to 0.24, which is adequately precise. CONCLUSIONS: Combining data from different WBA assessment instruments achieves acceptable reliability for assessing IMGs, provided that the panel of WBA assessment types are carefully selected and the assessors are calibrated.

Composite reliability of workplace-based assessment for international medical graduates.

OBJECTIVE: The fitness to practise of international medical graduates (IMGs) is usually evaluated with standardised assessment tests. Practising doctors should, however, be assessed on their performance rather than their competency, for which reason workplace-based assessment (WBA) has gained increasing attention. Our aim was to assess the composite reliability of WBA instruments for assessing the performance of IMGs. DESIGN AND SETTING: Between June 2010 and April 2015, 142 IMGs were assessed by 99 calibrated assessors; each cohort was assessed at their workplace over 6 months. The IMGs completed 970 case-based discussions (CBDs), 1741 Mini-Clinical Examination Exercises (mini-CEX) and 1020 multisource feedback (MSF) sessions. PARTICIPANTS: 103 male and 39 female candidates based in urban and rural hospitals of the Hunter New England Health region, from 28 countries (Africa, Asia, Europe, South America, South Pacific). MAIN OUTCOME MEASURES: The reliability of the three WBA tools; the composite reliability of the tools as a group. RESULTS: The composite reliability of our WBA toolbox program was good: the composite reliability coefficient for five CBDs and 12 mini-CEX was 0.895 (standard error of measurement, 0.138). When the six MSF results were included, the composite reliability coefficient was 0.899 (standard error of measurement, 0.125). CONCLUSIONS: WBA is a reliable method for assessing IMGs when multiple tools and assessors are used over a period of time. This form of assessment meets the criteria for "good assessment" (reliability ≥ 0.8) and can be applied in other settings.
