Abstract

Abstract: Background: Prior reports have suggested that the red blood cell distribution width (RDW) parameter could be measured as a prognostic indicator in pulmonary embolism (PE) patients, thereby helping to guide their care. However, no systematic analyses on this topic have been completed to date, and the exact relationship between RDW and PE remains to be fully clarified. We will therefore conduct a systematic literature review with the goal of defining the correlation between RDW and mortality in acute PE cases. Methods: The EMBASE, Web of Knowledge, PubMed, ClinicalTrials.gov, and Cochrane Library databases will be searched for all relevant studies published from inception through March 2021 using the following search strategy: ("red blood cell distribution width") AND ("pulmonary embolism"). Two authors will independently identify eligible studies and extract data. The Q and I 2 statistics will be used to judge heterogeneity among studies. Results: This study will establish the relative efficacy of RDW as a metric for predicting PE patient mortality. Conclusions: This study will offer a reliable, evidence-based foundation for the clinical utilization of RDW as a tool for gauging mortality risk in acute PE patients. Ethics and dissemination: As this is a protocol for a systematic review of previously published data, no ethical approval is required. Electronic dissemination of study results will be done through a peer-review publication or represented at a related conference.
