RESUMEN
WHAT IS KNOWN AND OBJECTIVE: Donor agencies provide most of the funds for HIV services in developing countries. Due to the global economic downturn, there has been a reduction in funding for HIV-related services in Nigeria. This study compared the willingness to pay (WTP)-willingness to accept (WTA) ratios for prevention of mother-to-child transmission (PMTCT) services to specialized clinical pharmacy services among patients of two Nigerian hospitals. METHODS: This was a cross-sectional survey using contingent valuation method at Ahmadu Bello University Teaching Hospital (ABUTH) and University of Nigeria Teaching Hospital (UNTH). WTP and WTA were elicited using an interviewer-administered questionnaire and a payment card. The responses to the WTP and WTA questions were reported as frequencies and percentages, while the amounts were determined as mean. All costs were obtained in Nigerian Naira (N360 = $1). RESULTS AND DISCUSSION: Of the 219 mothers who participated in the study, 172 (78.5%) had no health insurance. Primary prevention of HIV (PPV) had the highest "yes" WTP response of 152 (69.4%) and the highest mean WTP amount of N6067.20. It also had the least "no" WTA response of 162 (74.0%) and the least WTA amount of N232.09. Specialized clinical pharmacy service (SCPS) had the highest WTA/WTP ratio of 4.0826 in ABUTH and 9.3750 at UNTH. Its income effect was -3.0826. A 1% increase in income led to 0.0550 (95% CI: -0.3068 to 0.1968) decreased odds to pay for PPV. WHAT IS NEW AND CONCLUSION: Most patients assessed in this study were willing to pay for PPV than other services. Majority of them were also willing to forgo PMTCT Drugs Only. SCPS had the highest value for the patients, but they did not want to pay a high amount for it. Employment status, health insurance status, educational level and age were predictors of patients' WTP and WTA.
