Gerry Douglas and colleagues describe the rationale and their experience with scaling up electronic health records in six antiretroviral treatment sites in Malawi.
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
Bacille Calmette-Guérin (BCG) vaccination induces a marked increase in the interferon (IFN)-gamma response to Mycobacterium tuberculosis purified protein derivative (Mtb PPD) in UK adolescents, but not in Malawian adolescents. We hypothesized that Mtb PPD-induced IFN-gamma after BCG vaccination would be similar in infants from these 2 countries. Infants were vaccinated with BCG during the first 3-13 weeks of life. Three months after BCG vaccination, 51 (100%) of 51 UK infants had an IFN-gamma response to Mtb PPD, compared to 41 (53%) of 78 of Malawian infants, in whom responses varied according to their season of birth. We conclude that population differences in immune responses after BCG vaccination are observed among infants, as well as among young adults.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
