130 The National Emergency Department Overcrowding Scale and Perceived Staff Workload: Evidence for Construct Validity in a Pediatric Setting

Abstract

Our objective was to determine if there is a correlation between perceived staff workload and the National Emergency Department Overcrowding Scale (NEDOCS) in a pediatric ED (PED). Our primary outcome was the R squared, on univariate linear regression, between perceived workload measured by the raw sum of NASA Task Load Index (TLX) subscales and most recent hourly NEDOCS. Secondary outcomes included correlation between each TLX subscale and NEDOCS, correlation among specific staff roles, correlation between mean TLX responses for all staff in a given hour and most recent hourly NEDOCS, and the ROC AUC for the raw sum TLX categorical prediction of NEDOCS as “severely overcrowded” or not.
