Conditional cash transfers to improve health-focused outcomes: a global scoping review.

This scoping review assesses the use of conditional cash transfer (CCT) interventions – direct distribution of money to individuals conditional on their compliance to certain requirements – in randomised controlled trials, quasi-experimental studies and large community-based randomised trials with health-focused outcomes. Five databases were searched to identify 68 records published 2004–2021 from 25 countries (8 low- (32%), 5 lower middle- (20%), 6 upper middle- (24%) and 6 high-income (24%), according to the World Bank Categorisation (2017). Forty-six studies were unique (after excluding multiple publications on a single study). The most common outcomes assessed were infectious diseases (30%); maternal health (24%); vaccination rates (17%); and childhood developmental measures (17%). The number of participants receiving CCT in each study ranged from 47 to 5,788, with a median of 487 individuals. The number of total participants ranged from 72 to 14,000, with a median of 1,289 individuals. Fifteen percent of studies involved mobile CCT disbursement. More than a quarter of payments were greater than 50 USD (29%), and most payments were 20 USD or less (58%). Seventy-eight percent of unique full-length studies reported statistically significant CCT effects. Although CCTs remain controversial, a growing evidence base is emerging for their potential impact in specific health conditions. [ABSTRACT FROM AUTHOR]
