“…The higher the number of pills to be taken per day, the lower the chance that the patients studied would adhere to treatment. This result is consistent with that of the other study, 7 although it was not statistically significant. We also found similar results that suggest that side effects of the medication are the principal cause of non-adherence.…”

“…Only 37.6% of the patients had good BP control at the time of the study according to the standards used for BP lower than 140/90. 7 Upon comparing adherence to medication, defined by pill counts, among the risk and comorbidity factors in univariate analysis, the preponderant factor was the presence of side effects of medication that decreased adherence almost seven times when compared with the groups without side effects (Table 1). Another significant result was that the people who initiated the use of medication 2-5 years earlier had more than three times lower chance of adhering to the treatment when compared to the patients who began treatment 10-15 years ago.…”

“…However, this study presented a possible bias in selection by neither specifying whether the population studied was of hospital or primary care origin nor whether all patients accompanied in the public or private health-care system had the same chance of being selected for the study. 7 Despite being widely used in both clinical trial and community-care settings, the evidence of diagnostic performance of indirect methods of adherence to hypertension medication has been very scarce. The main goal of this study was to determine the sensitivity, specificity and predictive value of four indirect methods to measure adherence to medications in patients with HBP at a primary care centre.…”

High blood pressure (HBP) is one of the most important risk factors for morbidity and mortality in the world. Non-adherence to medication is associated with the lack of control of HBP. The objective of this study was to assess the validity of four indirect methods for measuring adherence to medication to control HBP in primary health care. A random sample of 120 hypertensive patients who were undergoing treatment for at least 2 months in a primary care unit in Florianó polis (Brazil) were included in the study. The independent variables were four indirect methods to measure adherence to medication: knowledge regarding the HBP medication, the blood pressure level, attitude regarding the medication intake (Morisky-Green test) and self-reported adherence. The classification of HBP was based on criteria established by the Brazilian Ministry of Health.The gold standard used for measuring adherence was the pill count. Logistic regression was used to estimate sensitivity (highest value of 88.2% for self-report), specificity (highest value of 70.7% for HBP control), positive predictive value (highest value of 46.4% for HBP control) and negative predictive value (highest value of 79.1% for Morisky-Green test) for each of the indirect methods. No indirect method of measuring adherence had a good positive predictive value for adherence, which was best predicted by patients' age and whether they managed to control HBP. The results also revealed low treatment adherence (31.2%) and low control of HBP (37.6%). Non-adherence was mainly associated with side effects of the treatment.

This study estimated adherence to anti-hypertensive medication using three indirect methods and their combinations in a cohort of patients with resistant hypertension in Rio de Janeiro, Brazil, 2005 IntroduçãoAs doenças cardiovasculares são a principal causa de mortalidade no Brasil e a hipertensão arterial está entre os seus principais fatores de risco 1 . A não-adesão ao tratamento medicamentoso é uma das principais causas das baixas taxas de controle da hipertensão 2 .A hipertensão arterial resistente é diagnosticada quando a pressão arterial de consultório é ≥ 140/90mmHg em pacientes em uso de três ou mais anti-hipertensivos em doses apropriadas, incluindo um diurético. A permanência prolongada desses níveis leva a lesões de órgãos-alvo e aumenta o risco de mortalidade por doenças cardiovasculares 3 .Dentre os vários fatores relacionados à ausên-cia de resposta ao tratamento anti-hipertensivo, a não-adesão à terapêutica apresenta-se como um dos maiores desafios, tanto para o diagnóstico da hipertensão arterial resistente quanto para o seu controle 4,5 . Hipertensos que interromperam o tratamento tiveram risco de infarto três vezes maior do que os que continuaram 5 . No Brasil, o impacto da não-adesão ao tratamento anti-hipertensivo pode ser avaliado pela importância dos acidentes vasculares encefálicos como causa de morte e, o adequado controle da hipertensão poderia reduzir esta mortalidade como ocorreu em outros países 6 .A baixa adesão é mais freqüente no nível primário de atenção do que entre pacientes de servi-NOTA RESEARCH NOTE

“…Blood pressure was measured three consecutive times for each patient, with a minimum interval of 3 minutes between measurements. We used the digital automatic device OMRON HEM -722C (Omron Healthcare Inc., Kyoto, Japan), validated by the protocols of the Association for the Advancement of Medical Instrumentation and those of the British Hypertension Society for international research Knowledge about the disease was assessed by 10 questions, with answers such as yes/no, standardized by Strelec et al 13 and used in national publications 8,14 . The knowledge was considered satisfactory for those patients who obtained scores ≥ 7, and unsatisfactory for those who obtained scores < 7 8 .…”

Abstract: Consciousness regarding the disease, the Morisky-Green test, and attendance to medical consultations did not influence blood pressure control.
