Abstract

Introduction: Skin and soft tissue infections are important causes of outpatient visits to medical clinics or hospitals.This study aimed to review the literature for the accuracy of Clinical Resource Efficiency Support Team(CREST) guideline in management of cellulitis in emergency department. Methods: Studies that had evaluatedcellulitis patients using the CREST guideline were quarried in Scopus, Web of Science, and PubMed database,from 2005 to the end of 2020. The quality of the studies was evaluated using Scottish Intercollegiate GuidelineNetwork (SIGN) checklist for cohort studies. Pooled area under the receiver operating characteristic curve (AUROC)of CREST guideline regarding the rate of hospital staymore than 24 hours, rate of revisit, and appropriatenessof antimicrobial treatment in management of cellulitis in emergency department was evaluated. Results:Seven studies evaluating a total of 1640 adult cellulitis patients were finally entered to the study. In evaluation ofthe rate of the appropriate treatment versus over-treatment, the pooled AUROC was estimated to be 0.38 (95%confidence interval (CI): 0.06 – 0.82), indicating low accuracy (AUROC lower than 0.5) of guideline for antimicrobialchoice. CREST II patients had a significantly lower odds ratio (OR) of revisiting the Emergency Department,OR=0.21 (95% CI: 0.009 – 0.47). Pooled AUROC value of 0.86 (CI95%: 0.84 – 0.89) showed accuracy of the CRESTclassification in prediction of being hospitalized more or less than 24 hours. Conclusion: CREST classificationshows good accuracy in determining the duration of hospitalization or observation in ED but it could lead toinevitable over/under treatment with empirical antimicrobial agents © 2021.
