Brief Summary:

INTRODUCTION: Studies prove that the pharmaceutical care (PC) increases the adherence to the antiretroviral; thus, they increase the undetectable viral load. The viral load diminishes, and the prevalence of undetectable viral load increases, as the levels of adherence to the treatment increase, being in general necessary high adhesion to reach the effectiveness therapeutic. Increasing the adherence levels, it increases the surviving chances and quality of life and diminishes the transmission risks. Studies demonstrate that the self-effectiveness expectation to use the medication correctly is the main predictor of adherence, and that the more complex the therapeutic regimen is, and the perception of side effects, the smaller the adherence is, highlighting the importance of preventing, identifying and solving the problems during the treatment with antiretroviral, problems related to the medication (PRM) through the PC.

OBJECTIVES: To evaluate the effectiveness of the PC on the adherence of HIV-patients to the antiretroviral therapy, identify, prevent and solve PRMs during the treatment.

METHODOLOGY: One-side randomized clinical trail controlled by non-intervention in parallel. 332 patients randomized are included in the control and intervention groups (PC). Questionnaires will be applied: sociodemographic, adherence to the antiretroviral through self-report, smoke, BECK (depression), CAGE (problems related with alcohol consumption) of self-effectiveness, expectation of results and social support. Each 4 months measure of viral load and CD4 will be carried out. The ones from the PC group will receive a card with information about the medication and all the medicines will be identified by different colors. The follow-up will last one year according to the instructions of DADER program.

HIV HIV Infections Behavioral: pharmaceutical care Not Applicable

Detailed Description:

Election of the sample: 332 will be selected consecutively patients registered in the SAE-Pelotas

GENERAL OBJECTIVE To evaluate the effectiveness of Pharmaceutical Care on the adherence to the antiretroviral therapy in HIV- positive patients.

PRIMARY OBJECTIVE The relative risk for adherence to the antiretroviral treatment among HIV-positive patients who receive Pharmaceutical Care and the ones that do not receive Pharmaceutical Care is different of 1.

SECONDARY OBJECTIVE The relative risk for undetectable viral load among HIV-positive patients that receive Pharmaceutical Care and the ones that do not receive Pharmaceutical Care is different of 1.
