Contraceptive Counseling Strategies for Women Living With Human Immunodeficiency Virus: The Role of Integrating Reproductive Health and Human Immunodeficiency Virus Services to Prevent Perinatal Transmission in Colombia

Objectives: This study aimed to evaluate the cost-effectiveness of 2 contraceptive counseling strategies in Colombia for women living with human immunodeficiency virus (HIV). The first integrates (1) reproductive health and HIV services (integrated model [IM]), and the second (2) offers these services separately (non-IM).Methods: Cost-effectiveness analysis from the third-party payer perspective (Colombian healthcare system). A decision analysis tree was used over a 24-month time horizon at a 3% discount rate, considering only direct costs. The outcome was the number of averted HIV perinatal transmission infections. We performed a discrete sensibility analysis and a probabilistic second-order sensitivity analysis with 10 000 iterations (Monte Carlo simulation).Results: Compared with the non-IM, the IM prevented 3% additional HIV perinatal transmission infections, with an incremental cost-effectiveness of US dollar 525 and the highest net monetary benefit at the proposed willingness to pay. In the probabilistic sensitivity analysis, we found a substantial amount of parameter uncertainty that challenges the evidence in favor of the cost-effectiveness of the IM strategy.Conclusions: This study opens the possibility of integrating reproductive health and HIV services for women living with HIV in Colombia. In addition, it raises the necessity to produce additional good quality local empirical evidence to inform better and support the estimation of the economic efficiency of such a model in the country.
