South Africa's HIV prevalence rate is estimated to be 5.7 million and at the end of2007 a total of 45845 HIV/AIDS adult patients were taking antiretroviral therapy (ART). The global incidence of HIV/AIDS has been slowly decreasing over the years but is still widespread. This disease is still more prevalent in sub-Saharan Africa than in other parts of the world, with more than 60% people living with HIV/AIDS. Highly active antiretroviral therapy (HAART), the treatment of choice, slows the progression of the human immunovirus but demands a high adherence rate in excess of 95%. Patients who are poorly informed about antiretrovirals (ARVs) and misunderstand medicine-taking instructions or experience unexpected side effects may interrupt therapy, predisposing them to the development of resistance. Such patients need information but, given the poor literacy skills prevalent in South Africa, written information is often not fully comprehended and is often written at too high a reading level. The objectives of this research project were to design, modify and evaluate HIV / AIDS patient education materials for low-literate isiXhosa speaking adults residing in Grahamstown and to examine their impact on the understanding of various aspects of the disease and its treatment. Pictograms illustrating common side effects of ARVs (e.g. stavudine, efavirenz, lamivudine), as well as various sources 'for purchasing nonprescription medicines, storage and medicine-taking instructions were designed and evaluated both qualitatively, using group discussions, and quantitatively through individual interviews where interpretation of the pictograms was assessed. These pictograms were incorporated in a patient information leaflet (PIL) which had been specifically designed for people with limited reading skills and was a simple document containing the minimum of essential text. A previously developed PIL was modified in collaboration with the target population and two versions were produced, one incorporating pictograms illustrating side effects, the other with none. Pictograms were used in both to illustrate other medicine-taking instructions. The PILs were tested objectively to assess the readability, format, content, and general design. They were translated into isiXhosa prior to being qualitatively and quantitatively evaluated in a low-literate isiXhosa speaking population. Understanding of the PILs was assessed by asking a series of questions about the PIL content. Participant opinion of the readability and appearance of the PIL was recorded. The relationship between PIL understanding and selected demographic variables was investigated. Findings from this study illustrated that well designed pictograms assist in the location of information in written leaflets and they may enhance understanding of the information. It was further demonstrated that education influences total understanding of PIL content thus emphasizing the need for tailor-written information in accordance with the education level of the target population. A desire to receive PILs incorporating pictograms was expressed by the majority of participants. Collaboration with the intended target population is essential to design culturally acceptable, easily interpreted pictograms and to produce user-friendly, easy-to-read, comprehensible patient education materials. The rigorous, iterative design, modification and testing process described in this study is one that should be adopted in producing all health-related education materials.
