Balancing feasibility and comprehensiveness: examining medications for reducing emergency hospital admissions

Emergency hospital admissions are common, with several interventions having been developed to reduce their rates. Bobrovitz et al. summarized the available body of evidence regarding pharmacologic therapies aimed at reducing emergency hospital admissions, and identified 28 medications for which high- or moderate-quality evidence supports their use, 11 of which were identified as being supported by current guideline recommendations. Additionally, the authors identified 28 medications supported by low- or very low-quality evidence, which can serve as targets for future research. The article by Bobrovitz et al. presents a good summary of the evidence, albeit with limitations in the search strategy that cannot guarantee the review as comprehensive. Despite this, the review has important implications for policymakers, guideline panels, researchers, clinicians, and funders since the identified medications can either be targets for quality improvement initiatives or for future research. Bobrovitz et al.’s review highlights the challenge that systematic reviewers face when balancing feasibility and comprehensiveness.
