Cost-effectiveness of integrated HIV prevention and family planning services for Zambian couples.

ABSTRACT

OBJECTIVE: To present the incremental cost from the payer's perspective and effectiveness of couples' family planning counseling (CFPC) with long-acting reversible contraception (LARC) access integrated with couples' voluntary HIV counseling and testing (CVCT) in Zambia. This integrated program is evaluated incremental to existing individual HIV counseling and testing and family planning services. DESIGN: Implementation and modelling. SETTING: Fifty-five government health facilities in Zambia. SUBJECTS: Patients in government health facilities. INTERVENTION Community health workers and personnel promoted and delivered integrated CVCT+CFPC from March 2013 to September 2015. MAIN OUTCOME MEASURES: We report financial costs of actual expenditures during integrated program implementation and outcomes of CVCT+CFPC uptake and LARC uptake. We model primary outcomes of cost-per- adult HIV infections averted by CVCT, unintended pregnancies averted by LARC, couple-years of protection against unintended pregnancy by LARC, and perinatal HIV infections averted by LARC. Costs and outcomes were discounted at 3% per year. RESULTS: Integrated program costs were $3 582 186 (2015 USD), 82 231 couples received CVCT+CFPC, and 56 409 women received LARC insertions. The program averted an estimated 7165 adult HIV infections at $384 per adult HIV infection averted over a 5-year time horizon. The program also averted 62 265 unintended pregnancies and was cost-saving for measures of cost-per-unintended pregnancy averted, cost-per-couple-year of protection against unintended pregnancy, and cost-per-perinatal HIV infection averted assuming 3 years of LARC use. CONCLUSION: Our intervention was cost-savings for CFPC outcomes and CVCT was effective and affordable in Zambia. Integrated couples-focused HIV and family planning was feasible, affordable, and leveraged HIV and unintended pregnancy prevention.
