摘要：Objective To evaluate the effect of vouchers for maternity care in public health-care facilities on the utilization of maternal health-care services in Cambodia. Methods The study involved data from the 2010 Cambodian Demographic and Health Survey, which covered births between 2005 and 2010. The effect of voucher schemes, first implemented in 2007, on the utilization of maternal health- care services was quantified using a difference-in-differences method that compared changes in utilization in districts with voucher schemes with changes in districts without them. Findings Overall, voucher schemes were associated with an increase of 10.1 percentage points (pp) in the probability of delivery in a public health-care facility; among women from the poorest 40% of households, the increase was 15.6 pp. Vouchers were responsible for about one fifth of the increase observed in institutional deliveries in districts with schemes. Universal voucher schemes had a larger effect on the probability of delivery in a public facility than schemes targeting the poorest women. Both types of schemes increased the probability of receiving postnatal care, but the increase was significant only for non-poor women. Universal, but not targeted, voucher schemes significantly increased the probability of receiving antenatal care. Conclusion Voucher schemes increased deliveries in health centres and, to a lesser extent, improved antenatal and postnatal care. However, schemes that targeted poorer women did not appear to be efficient since these women were more likely than less poor women to be encouraged to give birth in a public health-care facility, even with universal voucher schemes. a Institute of Health Policy and Management, Erasmus University Rotterdam, PO Box 1738, 3000 DR Rotterdam, Netherlands. b Institute of Health Economics and Management, University of Lausanne, Lausanne, Switzerland. c Institute of Tropical Medicine, Antwerp, Belgium. d University of Macedonia, Thessaloniki, Greece.

To isolate the effect of vouchers on the utilization of maternal health care, it is important to control for other inter- ventions that could have an influence. Since 1999, various forms of perfor- mance-based financing have linked the funding of public health-care facilities in some operational districts to predefined targets, most of which involved the provision of maternal and child health services. 14 Health equity funds and a government fee waiver scheme com- pensate facilities, mostly hospitals, for exempting poor patients from the need to pay fees. 15 , 16 In addition, at the end of 2007, the government introduced the nationwide Midwife Incentive Scheme, which pays midwives 10 United States dollars (US$) for each live birth they at- tended in a referral hospital and US$ 15 for each delivery they attended in a health centre, on top of the fee charged to the patient. 13 , 17 Methods We used data from the 2010 Cambodian Demographic and Health Survey (DHS), a nationally representative sample of 18 754 women of reproductive age.

Health-care facility compensation i) The facility was paid according to posted user fees (i.e. US$ 7.50 for each delivery and US$ 0.25 for each antenatal or postnatal care visit); ii) in a few operational districts only, the facility was paid even if a referral was made to a hospital for delivery. i) The facility was paid US$ 10 per package of four antenatal care visits, delivery and one postnatal care visit; ii) the facility was paid even if a referral was made to a hospital for delivery.
