Arms Assigned Interventions
Experimental: Situated Optimal Adherence Intervention
Situated Optimal Adherence Intervention: see 'Interventions' for more details.
Behavioral: Situated Optimal Adherence Intervention
Situated Optimal Adherence Intervention consists of 3 individual sessions (during consecutive medication pick-up visits to the clinic) -- patient-centered, non-judgmental, Motivational Interviewing- and theory-based, semi-structured, brief, candid conversations with a trained clinical care nurse using the Next Step Counseling approach. The intervention targets: accurate information about ART (mechanisms of HIV and antiretrovirals) and the development of mental imagery around it; promotion of perceived sense of ease and efficacy in working the ART regimen into the context of one's daily life and circumstances that may challenge drug use persistence; identification and refinement of skills that promote ease of adhering to one's ART regimen across the diverse and challenging contexts.
No Intervention: Adherence counseling, standard of care
Standard of care: Antiretroviral therapy adherence is discussed with patient (study participant) according to usual practice in the medical institution no special protocol followed.

Detailed Description:

Specific antiretroviral therapy (ART) can suppress HIV replication and consequently preserve the functioning of immune system. ART is a lifelong treatment with several different concomitantly administered oral medications. According to studies, low adherence to treatment is directly related to knowledge and beliefs about ART.

Studies have shown the success of different interventions increasing adherence to ART, but additional studies need to be carried out in order to determine the most effective components of the interventions and the methods most suitable considering the local context, that could be easily incorporated into the working routine of an medical institution (clinic) with limited extra resources.

Primary locations to implement activities directed at improving treatment adherence are medical institutions, i.e. the departments of infectious diseases where persons living with HIV/AIDS receive their ART.

The aim of the study is to conduct a small-scale intervention (randomised controlled) study implementing a brief adherence counseling targeting persons receiving ART.
