Monitoring Inequalities in the Health Workforce: The Case Study of Brazil 1991–2005

Introduction: Both the quantity and the distribution of health workers in a country are fundamental for assuring equitable access to health services. Using the case of Brazil, we measure changes in inequalities in the distribution of the health workforce and account for the sources of inequalities at sub-national level to identify whether policies have been effectiv

Perception of hypertensive patients about their non-adherence to the use of medication

This qualitative study aims to analyze the perception of patients with hypertension on their non-adherence to medication. 13 participants were interviewed, classified as non-adherent.The analysis was performed using the technique of thematic content analysis. Data points to contradictions in the approach of what is being adherent or not, the difficulty of adhering to the use of medication due to lifestyle habits, that forgetting is understood as a justification for non-compliance, and reinforces factors that hinder such practice, such as the use of many drugs, the presence of signs and symptoms and changes in daily routine. With complex conditions that involve non-adherence to treatment and the current context of the predominance of chronic diseases, it is essential to invest in innovative strategies of care for such people

Teste de Morisky-Green e Brief Medication Questionnaire para avaliar adesão a medicamentos

OBJETIVO: Analisar a confiabilidade e o desempenho da versão em português de instrumentos de avaliação da adesão ao tratamento anti-hipertensivo. MÉTODOS: Pacientes hipertensos atendidos de janeiro a setembro de 2010 em uma unidade de atenção primária em Porto Alegre, RS, foram selecionados aleatoriamente (n = 206). Na avaliação da adesão foram utilizadas versões em português do Teste de Morisky-Green (TMG) e do Brief Medication Questionnaire (BMQ). Foram analisados consistência interna, estabilidade temporal e desempenho com relação a três padrões-ouro: controle inadequado da pressão arterial (&gt; 140/90 mmHg); taxa insuficiente de retirada de medicação na farmácia da Unidade Básica de Saúde (< 80%); e a combinação de ambos. RESULTADOS: Dos pacientes avaliados, 97 utilizavam medicamentos dispensados somente pela farmácia da Unidade Básica de Saúde. Os testes apresentaram boa consistência interna: BMQ &#945; de Cronbach de 0,66 (IC95% 0,60;0,73) e o TMG 0,73 (IC95% 0,67;0,79). O desempenho do BMQ no domínio regime apresentou sensibilidade de 77%, especificidade de 58% e área sob a curva ROC de 0,70 (IC95% 0,55;0,86), e o TMG sensibilidade de 61%, especificidade de 36% e área sob a curva ROC de 0,46 (IC95% 0,30;0,62). A correlação entre o BMQ e o TMG foi de r = 0,28, p &gt; 0,001. A baixa adesão ao BMQ está associada a maiores níveis tensionais quando comparada com pacientes aderentes (148,4 [dp 20,1] vs 128,8 [dp 17,8], p < 0,001), mas não para o TMG. CONCLUSÕES: O BMQ apresentou melhor desempenho que o TMG, com maiores sensibilidade e especificidade. A avaliação da adesão pode auxiliar o clinico na discriminação entre uso inadequado da medicação e esquema terapêutico insuficiente.OBJETIVO: Analizar la confiabilidad y el desempeño de la versión en portugués de instrumentos de evaluación de la adherencia al tratamiento antihipertensivo.

METHODS: Hypertensive patients attending a primary healthcare unit in Porto Alegre, Southern Brazil, from January to September 2010, were randomly selected (n = 206). To evaluate adherence, Portuguese versions of the Morisky-Green test (MGT) and the Brief Medication Questionnaire (BMQ) were used. The analysis considered internal consistency, temporal stability and performance compared to three gold standards, which are: inadequate control of blood pressure (BP &gt; 140/90 mmHg); insufficient rate of medication acquisition at the institution's pharmacy

Task-Specific Effects of tDCS-Induced Cortical Excitability Changes on Cognitive and Motor Sequence Set Shifting Performance

In this study, we tested the effects of transcranial Direct Current Stimulation (tDCS) on two set shifting tasks. Set shifting ability is defined as the capacity to switch between mental sets or actions and requires the activation of a distributed neural network. Thirty healthy subjects (fifteen per site) received anodal, cathodal and sham stimulation of the dorsolateral prefrontal cortex (DLPFC) or the primary motor cortex (M1). We measured set shifting in both cognitive and motor tasks. The results show that both anodal and cathodal single session tDCS can modulate cognitive and motor tasks. However, an interaction was found between task and type of stimulation as anodal tDCS of DLPFC and M1 was found to increase performance in the cognitive task, while cathodal tDCS of DLPFC and M1 had the opposite effect on the motor task. Additionally, tDCS effects seem to be most evident on the speed of changing sets, rather than on reducing the number of errors or increasing the efficacy of irrelevant set filtering
