Purpose In the era of antiretroviral treatment (ART), treatment of HIV has become more manageable, and most patients with HIV benefit from long-term therapy in Japan. The aim of this qualitative study was to examine the experiences of patients with HIV/AIDS receiving mid- and long-term care in Japan. Methods A qualitative study was performed using semi-structured interviews at an outpatient clinic of a university hospital in the Greater Tokyo area. A total of 31 Japanese patients with HIV who had been receiving treatment for at least a year were interviewed in Japanese. Data from these interviews were analyzed by ‘content analysis’ (Krippendorff, 1980). Results The data were organized into the following seven themes: “feelings toward diagnosis of HIV infection”
“perceptions and behavior after diagnosis of HIV”
“attitudes toward HIV therapy”
“fear and hope for the future”
“feelings toward professional support”
“life changes after HIV therapy”
and “struggles in relationships with others”. Conclusions Some participants accepted themselves as HIV-positive, some did not when they were diagnosis. This difference of reaction had effect on attitudes toward HIV therapy. But all participants continued mid- and long-treatments owing to feeling well and receiving support from professionals. Additionally, it found that patients were felt stigma of HIV-positive similarly to another Asian countries. Therefore, we should provide the entire Japanese society with knowledge about HIV/AIDS and be early and constant intervention by professional teams after being infected.
