Pediatric Decentralization of ART in South Africa

The investigators will abstract clinical data from down-referral sites and from NHLS to determine whether children made it to their down-referral sites or whether children are in care at a different facility.

The investigators will attempt to contact and visit caregivers of children who are determined to be LTF from DNH or from down-referral sites. If located and after providing consent, caregivers will be administered a tracing questionnaire, or a verbal autopsy if their child has died.

For all children who started ART at DNH between 2004 and 2013, the investigators will abstract data on these children from the electronic medical system in South Africa called Tier.net.
