ObjectiveHealth economic evaluations are used in decision-making regarding resource allocation and it is imperative that they are completed with rigor. The primary objectives were to describe the characteristics and assess the quality of economic evaluations published in emergency medicine journals.MethodsTwo reviewers independently searched 19 emergency medicine-specific journals via Medline and Embase from inception until March 3, 2022. Quality assessment was completed using the Quality of Health Economic Studies (QHES) tool, and the primary outcome was the QHES score out of 100. Additionally, we identified factors that may contribute to higher-quality publications.Results7260 unique articles yielded 48 economic evaluations that met inclusion criteria. Most studies were cost-utility analyses and of high quality, with a median QHES score of 84 (interquartile range, IQR: 72, 90). Studies based on mathematical models and those primarily designed as an economic evaluation were associated with higher quality scores. The most commonly missed QHES items were: (i) providing and justifying the perspective of the analysis, (ii) providing justification for the primary outcome, and (iii) selecting an outcome that was long enough to allow for relevant events to occur.ConclusionsThe majority of health economic evaluations in the emergency medicine literature are cost-utility analyses and are of high quality. Decision analytic models and studies primarily designed as economic analyses were positively correlated with higher quality. To improve study quality, future EM economic evaluations should justify the choice of the perspective of the analysis and the selection of the primary outcome.© 2023.
