Background
 Globally, only 34% of ART eligible children aged <15
years are receiving ART
 Without treatment, 1/3 of HIV-infected children will not
see their first birthday and almost 1/2 will die before 2
years of age
 In Lesotho
 37,000 children are living with HIV
 38% of eligible children are receiving ART
 Average ART initiation is 5 years of age
 Long turn-around-time (TAT) for early infant
diagnosis (EID) has been identified as a significant
challenge

UNAIDS, 2013
Objectives
1) To identify delays in the EID
process, from sample collection to
receipt of results by caregiver and
infant ART initiation in HIV infected
infants
2) To determine the 6-8 week HIV
infection rate among HIV exposed
infants who had an EID test done
Methods
 Retrospective review of all 6-8 week-old, HIV-exposed
infants who received an HIV test in selected sites in
2011; central lab records linked to facility records
 25 purposefully selected study sites:
 Included sites from both hospitals and health
centers and each of the three geographic zones
 Included 11 hard-to-reach sites with higher-thanaverage EID turnaround time
 TAT for EID was calculated using abstracted dates from
laboratory EID database and registers
 Geometric means (with 95% CI) for TAT were calculated
and compared by region using linear mixed models

Results return for HIV infected infants
• HIV positive EID results are distributed by
EGPAF through mobile 3-G internet to health
facilities ahead of paper based results.
• Once Health care workers are informed,
community workers track the infant before the
appointment date.
Conclusions
• Average TAT from specimen collection to caregiver
receipt of test results in the study facilities was
approximately 2 months.
• The longest delay occurred between specimen receipt
in the central laboratory and result receipt at the
district laboratory
• HIV infected infants had rapid ART initiation due to a
system of expedited notification of positive results to
caregivers and same-day treatment initiation
• Interventions to expedite result transfer back to
facilities and in-country testing would allow for faster
initiation of infants on life-saving treatment
