Engineering Infection Controls to Reduce Indoor Transmission of Respiratory Infections

Le résumé fourni par la source

BACKGROUND: Engineering infection controls include a wide range of interventions used indoors to reduce occupants' exposure to respiratory pathogens. PURPOSE: To identify and describe primary studies evaluating the effects of engineering infection control interventions designed to reduce the spread of respiratory infections transmitted through indoor air. DATA SOURCES: MEDLINE, Embase, Global Health, Cochrane Central Register of Controlled Trials, CINAHL, Scopus, and Environmental Science Collection from database inception to 12 December 2023. STUDY SELECTION: English-language primary research articles evaluating engineering infection control interventions. DATA EXTRACTION: Publication information, population characteristics, intervention details, and all relevant outcomes were abstracted by a reviewer and verified by a second, senior reviewer. DATA SYNTHESIS: = 149). Harms, such as toxic byproducts, were rarely measured. LIMITATION: Exclusion of non-English-language publications and gray literature. CONCLUSION: There is substantial heterogeneity in the available evidence. Gaps in evidence include studies measuring efficacy outcomes that are highly relevant for human infection transmission or harms. Refinements in classification of interventions and outcomes could strengthen reporting of these evaluations. PRIMARY FUNDING SOURCE: National Institute for Occupational Safety and Health at the Centers for Disease Control and Prevention. (Registered on Open Science Framework [https://osf.io/5zmhd]).
