Based on a philosophy of empowerment, we developed the HIV Treatment, Virtual Nursing Assistance and Education intervention to equip persons living with HIV for managing their daily antiretroviral therapies. In this article, we describe the project and the process of developing it, which was carried out in three phases: (1) development of the intervention's clinical content, (2) generation of a multimedia presentation, and (3) implementation of our Web application via computer interface. The HIV Treatment, Virtual Nursing Assistance and Education consists of four interactive sessions at the computer, animated by a virtual nurse that takes the individual through the learning process about the capabilities necessary for taking the treatment. This information and strategies provided by the virtual nurse are specifically adapted to the participant, according to the responses he/she supplies. The virtual intervention approach, still experimental, is intended to be complementary with the actual clinical follow-up and has been developed in the context of reorganizing services and of the scarcity of resources. While we anticipate direct positive outcomes among the HIV clientele, it is also highly probable that this virtual support application will have ramifications among different clienteles who must also contend with the daily challenges of their health conditions.
