Levels of adherence to contemporary antiretroviral regimens and the likelihood of viral suppression: a cohort study in a Brazilian metropolis.

Levels of adherence to antiretroviral therapy (ART) can affect the likelihood of viral suppression differentially among ART regimens. In this prospective cohort conducted in Belo Horizonte, Brazil, we included 354 individuals who initiated ART containing tenofovir disoproxil fumarate/lamivudine/efavirenz in fixed-dose combination (TDF/3TC/EFV) or tenofovir disoproxil fumarate/lamivudine associated with dolutegravir (TDF/3TC + DTG). Viral suppression (viral load <50 copies/mL) was evaluated within six months of follow-up at different adherence levels and by therapeutic regimen.

Factors associated with high medication regimen complexity in primary care older adults in Brazil.

Purpose: Complex medication regimens are common among older adults and contribute to the occurrence of undesirable health outcomes. This study aims to investigate the factors associated with high medication regimen complexity in older people.

Methods: A cross-sectional study was conducted with older adults selected from two primary healthcare units.

Does switching from multiple to single-tablet regimen containing the same antiretroviral drugs improve adherence? A group-based trajectory modeling analysis.

Combination Antiretroviral Therapy (cART) in single-tablet regimens (STR) is a simplification strategy that can potentially improve medication adherence and clinical outcomes. We conducted a retrospective cohort study of 1206 patients using efavirenz, tenofovir and lamivudine in multiple-tablet regimen who switched to the STR containing the same active ingredients in a southeast metropolis in Brazil. We measured adherence using the proportion of days covered (PDC≥95%) and evaluated this outcome before and after the switch using paired non-parametric statistics.

New patient-reported outcome measure to assess perceived barriers to antiretroviral therapy adherence: the PEDIA scale.

This study sought to develop and evaluate a new patient-reported outcome measure to assess perceived barriers to antiretroviral therapy (ART) adherence. The Perceived Barriers to Antiretroviral Therapy Adherence (PEDIA) scale was developed based on individual interviews with patients. After pilot testing and assessing the evidence based on content analysis, the scale's revisions resulted in a 40-item version.

Comparison of the predictive performance of adherence measures for virologic failure detection in people living with HIV: a systematic review and pairwise meta-analysis.

A critical feature of an adherence assessment tool is its ability to predict virologic failure in people living with HIV (PLHIV). We, therefore, aimed to compare the predictive performance of commonly used adherence measures. We systematically searched MEDLINE, Embase and LILACS up to February 2018, to identify relevant observational studies comparing the effects of any two of the following adherence measurements on virologic outcomes: electronic monitoring, pill count, pharmacy refill, self-report and physician assessment.

Quality of life and associated characteristics: application of WHOQOL-BREF in the context of Primary Health Care.

This study aimed to identify the characteristics associated to quality of life (QOL) in users of four Basic Health Units (Unidades Básicas de Saúde, UBS) in Belo Horizonte, Minas Gerais. We conducted a cross-sectional study with 930 adult users enrolled in the selected UBS, using a questionnaire containing the WHOQOL-bref instrument and questions about sociodemographic characteristics, lifestyle and health conditions. Following descriptive analysis, we performed simple and multiple linear regression to evaluate the association between the exposure variables and the QOL domains.

An evaluation of elderly people's understanding of pharmacotherapy among those treated in the Primary Healthcare System in Belo Horizonte, Brazil.

There are a greater number of elderly people with diseases which has led to a greater use in medication and complexity in pharmacotherapy. The aim of this study was to understand the level of understanding on pharmacotherapy amongst the elderly and associated factors. An analytical transversal study was carried out in the Primary Health Care Units.

[Access to medicines for Alzheimer's disease provided by the Brazilian Unified National Health System in Minas Gerais State, Brazil].

This study evaluated barriers to access to treatment for Alzheimer's disease based on administrative cases involving cholinesterase inhibitors (ChEIs) and submitted to the Minas Gerais State Health Secretariat in Brazil in 2012 and 2013. Drawing on data from 165 randomly selected cases, the study addressed the following dimensions of access: geographic accessibility, accommodation, acceptability, availability, and affordability. The administrative processing to supply ChEIs took an average of 39 days and was influenced by characteristics of the path taken by the user.
