Results Data from 51 studies ( 15 more than previous review s ) and 22 cash transfer and voucher programmes  suggest that approaches tied to service use ( either via payment conditionalities or vouchers for selected services ) can increase use of antenatal care , use of a skilled attendant at birth and in the case of vouchers , postnatal care too .
The strongest evidence of positive effect was for conditional cash transfers and uptake of antenatal care , and for vouchers for maternity care services and birth with a skilled birth attendant .
However , effects appear to be shaped by a complex set of social and healthcare system barriers and facilitators .
There are few studies to indicate that programmes have led to improvements in quality of maternity care or maternal and newborn health outcomes .
Background Cash transfers and vouchers are forms of ‘ dem and -side financing ’ that have been widely used to promote maternal and newborn health in low- and middle-income countries during the last 15 years .
Mexico's conditional cash transfer programme increases cesarean section rates among the rural poor.
BACKGROUND Caesarean section rates are increasing in Mexico and Latin America . This study evaluates the impact of a large-scale , conditional cash transfer programme in Mexico on caesarean section rates . The programme provides cash transfers to participating low income , rural households in Mexico conditional on accepting health care and nutrition supplements . METHODS The primary analyses uses retrospective reports from 979 women in poor rural communities participating in an effectiveness study and r and omly assigned to incorporation into the programme in 1998 or 1999 across seven Mexican states . Using multivariate and instrumental variable analyses , we estimate the impact of the programme on caesarean sections and predict the adjusted mean rates by clinical setting . Programme participation is measured by beneficiary status , programme months and cash transfers . RESULTS More than two-thirds of poor rural women delivered in a health facility . Beneficiary status is associated with a 5.1 percentage point increase in caesarean rates ; this impact increases to 7.5 percentage points for beneficiaries enrolled in the programme for > or=6 months before delivery . Beneficiaries had significantly higher caesarean delivery rates in social security facilities ( 24.0 compared with 5.6 % among non-beneficiaries ) and in other government facilities ( 19.3 compared with 9.5 % ) . CONCLUSION The Oportunidades conditional cash transfer programme is associated with higher caesarean section rates in social security and government health facilities . This effect appears to be driven by the increases in disposable income from the cash transfer . These findings are relevant to other countries implementing conditional cash transfer programmes and health care requirements
