The dialysis orders objective structured clinical examination (OSCE): a formative assessment for nephrology fellows.

ABSTRACT:

Background

Few quantitative nephrology-specific simulations assess fellow competency. We describe the development and initial validation of a formative objective structured clinical examination (OSCE) assessing fellow competence in ordering acute dialysis.

Methods

The three test scenarios were acute continuous renal replacement therapy, chronic dialysis initiation in moderate uremia and acute dialysis in end-stage renal disease-associated hyperkalemia. The test committee included five academic nephrologists and four clinically practicing nephrologists outside of academia. There were 49 test items (58 points). A passing score was 46/58 points. No item had median relevance less than 'important'. The content validity index was 0.91. Ninety-five percent of positive-point items were easy-medium difficulty. Preliminary validation was by 10 board-certified volunteers, not test committee members, a median of 3.5?years from graduation. The mean score was 49 [95% confidence interval (CI) 46-51], ??=?0.68 (95% CI 0.59-0.77), Cronbach's ??=?0.84.

Results

We subsequently administered the test to 25 fellows. The mean score was 44 (95% CI 43-45); 36% passed the test. Fellows scored significantly less than validators (P?ConclusionsThe OSCE may be used to formatively assess fellow proficiency in three common areas of acute dialysis practice. Further validation studies are in progress.
