Methodology for Evidence Evaluation and Reporting of the NAEMSP Trauma Compendium Position Statements

BackgroundPosition statements from national organizations commonly vary in methodology for the evaluation of existing literature and the development of recommendations. Recent national recommendations have highlighted important components for evidence-based guidelines that can be feasibly incorporated in the creation of position statements and their resource documents. We describe the methodology developed to guide the creation of a compendium of 16 trauma-related position statements led by NAEMSP and partner organizations.MethodsEach position statement group developed trauma-related topic areas, primarily guided by the Population, Intervention, Comparison, and Outcome (PICO) framework. A structured literature search comprised of search terms aimed to identify relevant EMS and trauma-related scientific publications was performed for each topic area. Resource documents for each position statement included a description of the literature considered in forming recommendations, reported through evidence tables and a narrative description of the available literature. Where evidence was limited, consensus-based recommendations were developed using content experts and reviewed by the NAEMSP Standards and Clinical Practice Committee.ConclusionWe report a standardized methodology for literature review and development of recommendations as part of a compendium of trauma-related position statements from NAEMSP and partner organizations. This methodology can serve as a template for future position statements with ongoing refinement.
