AIDSTAR-One Case Study: Linking Resources for ART Adherence

  1. 1. AIDSTAR-One | CASE STUDY SERIES July 2012Linking Resources forAntiretroviral Therapy AdherenceThe Samastha Project in Karnataka, India A 10-year-old girl and several field workers are sitting in a room in the village of Kurugodu in the southwestern state of Karnataka, India. The girl looks happy and healthy. However, Courtesy of Herman Willems the small green booklet she carries shows that she is a child living with HIV. She is on antiretroviral therapy (ART) and outreach workers from Vimukthi, a nongovernmental organization (NGO) and partner in the Samastha project, have identified adherence problems. Because she accompanied her mother on a trip to a neighboring district and ran out of medication, the girl has missedMeeting of Samastha link workers,accredited social health activist, her ART drugs for a number of weeks. The outreach workers areand Vimukthi supervisors in Bellary talking to her and her guardian to help determine the best way toDistrict. get her back on treatment and avoid missing ART doses in the future. Her situation is not unusual: adhering to long-term HIV care and ART is challenging for all people living with HIV (PLHIV). It is especially so for PLHIV in rural villages such as those in Kurugodu, which is about three hours away from the nearest HIV care and ART center. Though the number of ART centers in Karnataka has increased dramatically over the past years, such problems as transport and incomplete information remain obstacles to care for PLHIV, and many are lost to follow-up (LFU) after diagnosis. Those who drop out of care will not receive the care or treatment for which they are eligible. And those who are on ART may have adherence problems or may default, rendering them more likely to transmit HIV or become ill.By Herman Willems Keeping PLHIV adherent to treatment was a key goal of Samastha, a five-year project that was launched in January 2007 with support from the U.S. President’s Emergency Plan for AIDS Relief through the U.S.AIDSTAR-OneJohn Snow, Inc.

TheSamastha database, which collected informationon all adherence assessments performed by linkworkers, showed that overall adherence was high:nearly all (95 percent) of over 24,000 PLHIV onART who participated in the project showed goodadherence (adherence greater than 95 percent).4Another 2.7 percent had some adherence problems(80 to 95 percent), while 2.3 percent had pooradherence (less than 80 percent adherence).When link workers found inconsistent compliancewith treatment, they provided extra counseling andhelped clients identify ways to improve adherence.Outreach workers’ home visits largely focused onretrieving PLHIV who were missing or LFU. Theydid so in villages that were not covered by linkworkers and in urban areas where no link workerscheme was implemented. While both link workersand outreach workers would respond to adherenceproblems that were identified at the facility level, linkworkers would provide more continuous supportthrough regular visits to homes of PLHIV.The female sex worker peer educators were a thirdtype of field worker that Samastha used. Their rolein adherence support was similar to that of theoutreach workers and link workers, but limited to the Figure 2.
