Previous studies applied various reference standards and measures to validate five-level triage systems. They either created their own reference standard or used a combination of severity/resource measures.
ObjectiveTo examine whether peppy comments from attending physicians increased the workload of residents working in the emergency department (ED).MethodsWe conducted two parallel-group, assessor-blinded, randomized trials at the ED in a tertiary care hospital in western Japan. Twenty-five residents who examined either ambulatory (J(^o^)PAN-1 Trial) or transferred patients (J(^o^)PAN-2 Trial) in the ED on weekdays. Participants were randomly assigned to groups that either received a peppy message such as “Hope you have a quiet day!” (intervention group) or did not (control group) from the attending physicians. Both trials were conducted from June 2014 through March 2015. For each trial, residents rated the number of patients examined during and the busyness and difficulty of their shifts on a 5-point Likert scale.ResultsA total of 169 randomizations (intervention group, 81; control group, 88) were performed for the J(^o^)PAN-1 Trial, and 178 (intervention group, 85; control group, 93) for the J(^o^)PAN-2 Trial. In the J(^o^)PAN-1 trial, no differences were observed in the number of ambulatory patients examined during their shifts (5.5 and 5.7, respectively, p = 0.48), the busyness of their shifts (2.8 vs 2.8; p = 0.58), or the difficulty of their shifts (3.1 vs 3.1, p = 0.94). However, in the J(^o^)PAN-2 trial, although busyness (2.8 vs 2.7; p = 0.40) and difficulty (3.1 vs 3.2; p = 0.75) were similar between groups, the intervention group examined more transferred patients than the control group (4.4 vs 3.9; p = 0.01).ConclusionsPeppy comments from attending physicians had a minimal jinxing effect on the workload of residents working in the ED.Trial RegistrationUniversity Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR), UMIN000017193 and UMIN000017194.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
