Universal Rapid Human Immunodeficiency Virus Screening at Delivery: A Cost-Effectiveness Analysis.

Objective: To determine the cost-effectiveness of universal maternal HIV screening at time of delivery to decrease mother-to-child transmission (MTCT), by comparing the cost and quality-adjusted life years (QALYs) of universal rapid HIV screening at time of delivery to two current standards of care for prenatal HIV screening in the United States. Study Design: We conducted a cost-effectiveness analysis to compare the cost and QALY of universal intrapartum rapid HIV screening with two current standards of care: (I) opt-out rapid HIV testing limited to patients without previous third-trimester screening and (II) opt-out rapid HIV testing limited to patients without any prenatal screening. We developed a decision-tree model and performed sensitivity analyses to estimate the impact of variances in QALY, estimated lifetime medical costs, HIV prevalence, and cumulative incidence. Results: The incremental cost-effectiveness ratio for universal screening was $7,973.45/QALY. The results remained robust to sensitivity analysis, except for annual cumulative incidence. In areas with an annual cumulative incidence rate of <0.02% for reproductive-age women, the incremental cost-effectiveness ratio for the expanded program would exceed $89,926.94/QALY, approaching the commonly applied cost-effectiveness thresholds ($100,000/QALY). Conclusions: Intrapartum universal rapid HIV screening to decrease MTCT appears cost-effective in populations with high HIV incidence in the United States.

Implementation of universal rapid human immunodeficiency virus screening on labor and delivery.

BACKGROUND: A case of mother to child transmission (MTCT) of HIV at a medical center in Washington, DC, resulted in the implementation of universal opt-out rapid testing of patients admitted for delivery. This article evaluates the policy's efficacy and implementation. METHODS: We evaluated the implementation using the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. RESULTS: We could not evaluate decrease in MTCT rate secondary to low sample size (n = 3324) and no true-positive results. Patients not tested (n = 458) were predominately secondary to physician omission (93.7%) and were more likely to be White (p < 0.01) and older (p < 0.01). There was a negative relationship with physician omission over time. CONCLUSION: The policy was successfully implemented with decreasing proportions of patients not tested. Earlier inclusion of testing into standard admission orders and nurse-based approach may have expedited adoption. Given the low incidence of new HIV diagnosis in labor, we were unable to assess decrease in MTCT.
