Input: We included ten papers reporting results from six intervention studies. Overall, design quality and analysis limited the risks of bias. Several CCT programmes provided strong evidence of a positive impact on the use of health services, nutritional status and health outcomes, respectively assessed by anthropometric measurements  and self-reported episodes of illness. It is hard to attribute these positive effects to the cash incentives specifically because other components may also contribute. Several studies provide evidence of positive impacts on the uptake of preventive services by children and pregnant women. We found no evidence about effects on health care expenditure. Conditional cash transfer programmes have been the subject of some well-designed evaluations, which strongly suggest that they could be an effective approach to improving access to preventive services. Their replicability under different conditions - particularly in more deprived settings - is still unclear because they depend on effective primary health care and mechanisms to disburse payments. Further rigorous evaluative research is needed, particularly where CCTs are being introduced in low income countries, for example in Sub-Saharan Africa or South Asia.
Output:

We found 29 papers on the impact of conditional cash transfers (CCT) on access to care and health outcomes. Of these, ten papers, reporting results from six studies, satisfied the inclusion criteria; four of these studies were randomised experiments. Despite a number of methodological weaknesses in some studies, overall the research evidence suggests that CCT schemes may result in a number of benefits to health for poor populations. Many conditional cash transfer programmes include a number of components, including incentivising attendance for health education, measurements of height and weight, immunisations and nutritional supplementation. Conditional cash transfer programmes appear to be an effective way to increase the uptake of preventive services and encourage some preventive behaviours. In some cases programmes have noted improvement of health outcomes, though it is unclear to which components this positive effect should be attributed.
