Universal HIV Screening at Postnatal Points of Care: Which Public Health Approach for Early Infant Diagnosis in Côte d'Ivoire?

BACKGROUND: Universal HIV pediatric screening offered at postnatal points of care (PPOC) is an entry point for early infant diagnosis (EID). We assessed the parents acceptability of this approach in Abidjan Cote dIvoire. METHODS: In this cross-sectional study trained counselors offered systematic HIV screening to all children aged 6-26 weeks attending PPOC in three community health centers with existing access to HAART during 2008 as well as their parents/caregivers. HIV-testing acceptability was measured for parents and children; rapid HIV tests were used for parents. Both parents consent was required according to the Ivorian Ethical Committee to perform a HIV test on HIV-exposed children. Free HIV care was offered to those who were diagnosed HIV-infected. FINDINGS: We provided 3013 HIV tests for infants and their 2986 mothers. While 1731 mothers (58%) accepted the principle of EID only 447 infants had formal parental consent 15%; 95% confidence interval (CI): [14%-16%]. Overall 1817 mothers (61%) accepted to test for HIV of whom 81 were HIV-infected (4.5%; 95% CI: [3.5%-5.4%]). Among the 81 HIV-exposed children 42 (52%) had provided parental consent and were tested: five were HIV-infected (11.9%; 95% CI: [2.1%-21.7%]). Only 46 fathers (2%) came to diagnose their child. Parental acceptance of EID was strongly correlated with prenatal self-reported HIV status: HIV-infected mothers were six times more likely to provide EID parental acceptance than mothers reporting unknown or negative prenatal HIV status (aOR: 5.9; 95% CI: [3.3-10.6] p = 0.0001). CONCLUSIONS: Although the principle of EID was moderately accepted by mothers fathers acceptance rate remained very low. Routine HIV screening of all infants was inefficient for EID at a community level in Abidjan in 2008. Our results suggest the need of focusing on increasing the PMTCT coverage involving fathers and tracing children issued from PMTCT programs in low HIV prevalence countries.
