Summaryobjectives To determine the proportion of patients returning to antiretroviral treatment (ART) and factors associated with their return in a resource-limited setting. We successfully traced 85%, of whom 30% had died. Of the 1580 patients found alive, 25% had transferred to another ART clinic, 21% had collected drugs from other sources, 11% had treatment gaps; 40% had stopped taking drugs, 1% had not started taking drugs despite collecting them and 2% refused to be interviewed. Of the 1158 LTFU patients who had not died, transferred out or declined to be interviewed, 89% promised to return to their ART clinic and 74% actually did. The probability of returning to the clinic was significantly associated with being women, aged over 39 at ART initiation and having either treatment gaps or uninterrupted therapy. The B2C project reduced the proportion of patients finally classified as LTFU by 59%.conclusion Early active follow-up of LTFU patients resulted in marked improvement in known patient outcomes and improved retention in the treatment programme.keywords antiretroviral therapy, loss to follow-up

BackgroundLoss to follow-up is a major challenge of antiretroviral treatment (ART) programs in sub-Saharan Africa. Our objective was to a) determine true outcomes of patients lost to follow-up (LTFU) and b) identify risk factors associated with successful tracing and deaths of patients LTFU from ART in a large public sector clinic in Lilongwe, Malawi.MethodsPatients who were more than 2 weeks late according to their last ART supply and who provided a phone number or address in Lilongwe were eligible for tracing. Their outcomes were updated and risk factors for successful tracing and death were examined.ResultsOf 1800 patients LTFU with consent for tracing, 724 (40%) were eligible and tracing was successful in 534 (74%): 285 (53%) were found to be alive and on ART; 32 (6%) had stopped ART; and 217 (41%) had died. Having a phone contact doubled tracing success (adjusted odds ratio, aOR = 2.1, 95% CI 1.4-3.0) and odds of identifying deaths [aOR = 1.8 (1.2-2.7)] in patients successfully traced. Mortality was higher when ART was fee-based at initiation (aOR = 2.3, 95% CI 1.1-4.7) and declined with follow-up time on ART. Limiting the analysis to patients living in Lilongwe did not change the main findings.ConclusionAscertainment of contact information is a prerequisite for tracing, which can reveal outcomes of a large proportion of patients LTFU. Having a phone contact number is critical for successful tracing, but further research should focus on understanding whether phone tracing is associated with any differential reporting of mortality or LTFU.

BackgroundIn 2012, alarmingly high rates of oral artemisinin monotherapy availability and use were detected along Eastern Myanmar, threatening efforts to halt the spread of artemisinin resistance in the Greater Mekong Subregion (GMS), and globally. The aim of this paper is to exemplify how the use of supply side evidence generated through the ACTwatch project shaped the artemisinin monotherapy replacement malaria (AMTR) project’s design and interventions to rapidly displace oral artemisinin monotherapy with subsidized, quality-assured ACT in the private sector.MethodsThe AMTR project was implemented as part of the Myanmar artemisinin resistance containment (MARC) framework along Eastern Myanmar. Guided by outlet survey and supply chain evidence, the project implemented a high-level subsidy, including negotiations with a main anti-malarial distributor, with the aim of squeezing oral artemisinin monotherapy out of the market through price competition and increased availability of quality-assured artemisinin-based combinations. This was complemented with a plethora of demand-creation activities targeting anti-malarial providers and consumers. Priority outlet types responsible for the distribution of oral artemisinin monotherapy were identified by the outlet survey, and this evidence was used to target the AMTR project’s supporting interventions.ConclusionsThe widespread availability and use of oral artemisinin monotherapy in Myanmar has been a serious threat to malaria control and elimination in the country and across the region. Practical anti-malarial market evidence was rapidly generated and used to inform private sector approaches to address these threats. The program design approach outlined in this paper is illustrative of the type of evidence generation and use that will be required to ensure effective containment of artemisinin drug resistance and progress toward regional and global malaria elimination goals.
