The effect of cognitive aid design on the perceived usability of critical event cognitive aids.
Critical events require that clinicians process information and make decisions quickly. To reduce mental workload during such events, cognitive aids have been developed. We have previously observed that designing such aids to facilitate discrete information transfer decreased time to information finding. However, whether clinicians perceive aids designed for discrete information transfer as more usable than step-by-step designs remains unclear. We hypothesized that experimental cognitive aids designed for discrete information transfer would be judged more usable than step-by-step Linear aids. ⋯ During simulated critical events, cognitive aids designed for discrete information transfer were considered more usable than step by step Linear aids. Specific themes governing usability were identified during mixed methods analysis. Further work is needed to optimize cognitive aid use among anesthesia clinicians.
