Uptake of early infant diagnosis and factors associated with its timely completion among HIV exposed infants at Lira Regional Referral Hospital: a retrospective cohort study

BackgroundHIV exposed infants (HEIs) are at a higher risk of infant mortality compared to their counterparts who are not HIV exposed. Early Infant Diagnosis (EID) is the critical first step in reducing HIV-related infant mortality through prompt identification of HIV-infected infants and subsequent initiation of antiretroviral therapy. However, there is limited information on Uptake of EID and factors associated with its timely completion among HIV exposed infants. Therefore, this study aimed at determining the uptake of EID and factors associated with its timely completion among HIV exposed infants at Lira Regional Referral Hospital (LRRH). MethodsThe study was a retrospective cohort of 252 HEIs born in the period of 1st January 2021 to 31st December 2021 chosen through consecutive sampling. Data abstraction tools were used to collect data on uptake of 1st, 2nd, 3rd DNA-PCR and final rapid test from mother-baby pair files and EID register. The main outcome was Uptake of EID and classified as timely and untimely according to the PMTCT guideline. Data was analyzed using descriptive statistics and generalized estimating equations (GEE) with poisson family, log link and unstructured correlation structure. ResultsThe timely uptake of EID among HIV exposed infants at 4-6 weeks, 9 months, 6 weeks after cessation of breastfeeding and 18 months were 80.1% (95% CI:74.5-84.7), 84.2% (95% CI:79.0-88.3), 3.7% (95% CI:2.0-7.0) and 78.8% (95% CI:73.2-83.6) respectively. Having cotrimoxazole given was associated with timely completion of EID [aRR=2.974, 95% CI (1.45-6.10)] ConclusionUptake of EID among HEIs was sub-optimal, below the Ministry of Healths 90% target. Timely cotrimoxazole administration was associated with EID completion,
