Aim: The Cardiac Arrest Simulation Test (CASTest) assesses resuscitation knowledge and skills during a simulated cardiac arrest. The aim of this study is to validate an alternative scoring system for measuring individual candidate performance during research involving the CASTest. Methods: The performance of 537 participants was measured using the new scoring system. In addition, assessors assigned a global pass-fail decision. Differences in scores were compared between to global pass/ fail decisions, professional groups and those nominated to become instructors. Correlations between CASTest domain scores and overall score, multiple choice scores and other practical tests (airway test and initial assessment and resuscitation test) scores were measured. This provided opportunity to cross reference achievement in other areas of course assessment with this alternative scoring system. Results: 413 (76.9%) passed the CASTest and 124 (23.1%) failed. The total performance score was significantly higher in those that passed than in those that failed (median 77 vs 62.5, P<0.0001). There were no differences between professions. Senior staff performed slightly better than junior staff (median 74 and 72 respectively, P=0.01). Excellent participants (identified as having instructor potential) scored significantly higher than the other participants (median 94 and 72 respectively, P <0.0001). A strong correlation was demonstrated between domains in the CASTest (rho 0.72-0.82, P<0.01). Other assessment outcomes for the ALS course correlated poorly with CASTest scores (rho = 0.27-0.37, P<0.01). Conclusion: This new simple scoring system can be used to better characterise performance on the ALS course CASTest than the current binary pass-fail outcome.
