Summary of published evidence

Out-of-facility individual models vary according to where in the community the services are provided, as well as what services are delivered and by whom. They can be divided into three categories: fixed community points, mobile outreach ART delivery, and home delivery.

Fixed community points

Promising results have been found from fixed community points with evidence from the community drug distribution point (CDDP) model in Uganda and the community ART distribution points (PODI) in the Democratic Republic of the Congo (DRC). In Uganda, cross-sectional outcomes at study endpoint for clients initiating ART from 2004 to 2009 (median time on ART 5.7 years; IQR 4.1-7.2) in the CDDP model were 69% retention, 17% dead, 6% transferred out and 9% loss to follow up (LTFU). In CDDP clients, viral load suppression (<1,000 copies/mL) was 93% (median time on ART 7.0 years; IQR 5.0-8.0) (1). In a subsequent conference abstract, LTFU was reported as 16.5% in the facility arm and 4.28% in the CDDP arm (p<0.0001) (2). A costing comparison study costed the TASO model (including TASO run clinics for new initiations and the CDDP model for stable clients) at US$74 per visit and US$332 annual cost per client compared with a mobile ART delivery model utilising expert clients to dispense ART (US$45; US$404) and a facility based nurse-led model (US$38; US$257) in Uganda (3). In the DRC, a retrospective cohort analysis found LTFU and death amongst PODI participants of 2.2% and 0.1% (at 6 months), 4.8% and 0.2% (at 12 months) and 9% and 0.3% (at 24 months) with overall crude attrition of 5.66/100py with little variation over time (4).

Mobile outreach ART delivery

There is limited published evidence of utilizing mobile outreach services to distribute ART refills outside of the health facility. Two conference abstracts report on outcomes. In Swaziland, health facilities were offered a choice of three ART delivery models for implementation. One health centre and one clinic implemented an outreach service to support remote communities; one health centre chose to implement ART adherence clubs (ACs); and 12 clinics implemented community ART groups (CAGs). Twelve-month retention was 77% for the outreach service model (n=102), 96% in ACs (n=289) and 81% in CAGs (n=336) (5). In South Africa, comprehensive ART services (including ART refills) were provided by mobile outreach on South African-Zimbabwean border farms to vulnerable, highly mobile Zimbabwean migrant farm workers and their families (6). The intervention piloted a travel package, including a 3-month ART refill. Viral suppression was 91.2%, and of those clients who indicated planned travel to Zimbabwe, only 2% did not return within three months of their planned return date. 

Home delivery

There are two cluster randomized controlled trials from Kenya and Uganda reporting outcomes from home ART delivery models. In Uganda, there was no difference between the virological failure rates for home versus for facility care (rate ratio, RR, 1.04, 0.78-1.40; equivalence shown) (7). Mortality rates were also similar between the groups (0.95, 0.71-1.28). Health services and patient cost year were less for home delivery compared with facility refill (US$793 vs. $838 for health services and $18 vs. $54 for patient). In Kenya, no significant intervention-control differences were found with regard to detectable viral load, mean CD4 count, change in ART regimen, new opportunistic infections or pregnancy rates. Intervention clients made half as many clinic visits as did controls (8).
