Digital health evidence for a global health investment
4,538 records. 1,330 screened. 193 studies included.
A global health research team needed the primary studies on digital decision-support tools, for clinical health workers and for patients, and their effect on the efficiency of service delivery in low- and middle-income countries. PICO Portal PLUS+ methodologists led title and abstract screening and full-text review in the team's own workspace; data extraction and risk of bias were done jointly with the research team.
Two reviewers screened the first 10 percent to calibrate against the criteria. Screening prioritization then ranked the remaining records, and screening stopped once estimated recall reached 95 percent. The 3,208 lowest-ranked records were reported as not screened, not as exclusions. Of 378 full texts assessed, 193 studies were included, with every exclusion coded by reason.
