Clientele population/catchment area

The Chatsworth CRS, established in 2003, is located in Chatsworth, KwaZulu-Natal, a province in South Africa with the highest HIV prevalence. Chatsworth is an urban area south of Durban, approximately 14km south-west of the Durban city center. The CRS is located on the property of the RK Khan Hospital, which is a regional and district hospital. The CRS is easily accessible via public transportation including rail, bus and minibus taxis. The participants are recruited from urban and rural areas surrounding the Chatsworth Clinical Research Site.

How have you been able to get CARES clients

The main recruitment center is the RK Khan ARV clinic which is located adjacent to the Chatsworth Clinical Research Site, on the premises of R K Khan Hospital. Participants have also been referred to the community team due to knowledge being disseminated in the community regarding the study. Additionally, recruitment is from the support groups for people living with HIV.

Challenges encountered

Initially participants were concerned about potentially changing the treatment that they were stable on. However, with community education and information obtained from previous trials we were able address all queries and concerns. Another challenge was the recruitment from the RK Khan ARV clinic as many of the patients attending the clinic required specialized management and hence were not ideal candidates for the CARES trial. To overcome this, participants are recruited from alternate sources. The Hepatitis B Core Positivity Rate discovered during screening was higher than anticipated and hence resulted in a higher than expected screening to enrolment ratio.

Participants experience and how they have benefited

The participants have expressed that they have benefited from education and sensitization sessions conducted due to the CARES trial. They are pleased to learn that there are potential alternate methods of taking ARVS.

How participants perceive the new treatment

The participants have remarked that injectables are a good alternate to taking ARVs orally and especially assist with adherence to treatment. They feel it will motivate those participant who are not already on treatment.
