The Prevalence of Stages of Heart Failure in Primary Care: A Population-Based Study

BACKGROUND Planning strategies to prevent heart failure (HF) in developing countries require epidemiologic data in primary care. The purpose of this study was to estimate the prevalence of HF stages and their phenotypes, HF with preserved ejection fraction (HFPEF), and HF with reduced EF (HFREF) and to determine B-type natriuretic peptide (BNP) levels to identify HF in the adult population. METHODS AND RESULTS This is a cross-sectional study including 633 individuals, aged ≥45 years, who were randomly selected and registered in a primary care program of a medium-sized city in Brazil. All participants were underwent clinical evaluations, BNP measurements, electrocardiograms, and tissue Doppler echocardiography in a single day. The participants were classified as stage 0 (healthy, 11.7%), stage A (risk factors, 36.6%), stage B (structural abnormalities, 42.7%), or stage C (symptomatic HF, 9.3%). Among patients with HF, 59% presented with HFPEF and 41% presented with HFREF. The mean BNP levels were 20 pg/mL(-1) in stage 0, 20 pg/mL(-1) in stage A, 24 pg/mL(-1) in stage B, 93 pg/mL(-1) in HFPEF, and 266 pg/mL(-1) in HFREF. The cutoff BNP level with optimal sensitivity (92%) and specificity (91%) to identify HF was 42 pg/mL(-1). CONCLUSION The present study demonstrated a high prevalence of individuals at risk for HF and the predominance of HFPEF in a primary care setting. The clinical examination, along with BNP and tissue Doppler echocardiography, may facilitate early detection of stages A and B HF and allow implementation of interventions aimed at preventing progression to symptomatic HF.

Compliance with the Prescription of Antihypertensive Medications and Blood Pressure Control in Primary Care

Background: Hypertension is the most prevalent risk factor for cardiovascular disease, and its proper control can prevent the high morbidity and mortality associated with this disease. Objective: To assess the degree of compliance of antihypertensive prescriptions with the VI Brazilian Guidelines on Hypertension and the blood pressure control rate in primary care. Methods: Cross-sectional study conducted between August 2011 and November 2012, including 332 adults ≥ 45 years registered in the Family Doctor Program in Niteroi and selected randomly. The analysis included the prescribed antihypertensive classes, doses, and frequencies, as well as the blood pressure (BP) of the individuals. Results: The rate of prescription compliance was 80%. Diuretics were the most prescribed medications, and dual therapy was the most used treatment. The most common non-compliances were underdosing and underfrequencies. The BP goal in all cases was < 140/90 mmHg, except for diabetic patients, in whom the goal was set at < 130/80 mmHg. Control rates according to these goals were 44.9% and 38.6%, respectively. There was no correlation between prescription compliance and BP control. Conclusions: The degree of compliance was considered satisfactory. The achievement of the targets was consistent with national and international studies, suggesting that the family health model is effective in BP management, although it still needs improvement. Fundamento: A hipertensão arterial é o fator de risco mais prevalente para a doença cardiovascular e seu controle adequado pode prevenir a elevada morbi-mortalidade associada a esta doença. Objetivo: Avaliar o grau de conformidade das prescrições de anti-hipertensivos com as VI Diretrizes Brasileiras de Hipertensão e a taxa de controle pressórico na atenção básica. Métodos: Estudo transversal conduzido entre agosto de 2011 e novembro de 2012, incluindo 332 adultos ≥ 45 anos cadastrados no Programa Médico de Família de Niterói e selecionados aleatoriamente. Foram analisadas as classes de anti-hipertensivos prescritos, suas doses e frequências, bem como a pressão arterial (PA) dos indivíduos. Resultados: A taxa de conformidade das prescrições foi de 80%. Diuréticos foram as medicações mais prescritas e a terapia dupla foi o tratamento mais utilizado. As não conformidades mais comuns foram subdoses e subfrequências. A meta de PA para todos os casos foi < 140/90 mmHg, exceto para diabéticos, que foi < 130/80 mmHg. As taxas de controle de acordo com essas metas foram de 44,9% e 38,6%, respectivamente. Não houve correlação entre conformidade da prescrição e controle pressórico. Conclusões: O grau de conformidade foi considerado satisfatório. O alcance das metas foi compatível com estudos nacionais e internacionais, sugerindo que o modelo de saúde da família é efetivo no manejo da PA, embora ainda necessite aprimoramento.

Prevalence of Risk for Obstructive Sleep Apnea Syndrome and Association With Risk Factors in Primary Care

Background Obstructive sleep apnea syndrome (OSAS) is a chronic, progressive disease with high morbidity and mortality. It is underdiagnosed, especially among women. Objective To study the prevalence of high risk for OSAS globally and for the Berlin Questionnaire (BQ) categories, and to evaluate the reliability of the BQ use in the population studied. Methods Observational, cross-sectional study with individuals from the Niterói Family Doctor Program, randomly selected, aged between 45 and 99 years. The visits occurred between August/2011 and December/2012. Variables associated with each BQ category and with high risk for OSAS (global) were included in logistic regression models (p < 0.05). Results Of the total (616), 403 individuals (65.4%) reported snoring. The prevalence of high risk for OSA was 42.4%, being 49.7% for category I, 10.2% for category II and 77.6% for category III. Conclusion BQ showed an acceptable reliability after excluding the questions Has anyone noticed that you stop breathing during your sleep? and Have you ever dozed off or fallen asleep while driving?. This should be tested in further studies with samples mostly comprised of women and low educational level individuals. Given the burden of OSAS-related diseases and risks, studies should be conducted to validate new tools and to adapt BQ to better screen OSAS.

Evaluation of Quality of Life in Patients with and without Heart Failure in Primary Care

Background Heart failure (HF) is a major public health issue with implications on health-related quality of life (HRQL). Objective To compare HRQL, estimated by the Short-Form Health Survey (SF-36), in patients with and without HF in the community. Methods Cross-sectional study including 633 consecutive individuals aged 45 years or older, registered in primary care. The subjects were selected from a random sample representative of the population studied. They were divided into two groups: group I, HF patients (n = 59); and group II, patients without HF (n = 574). The HF group was divided into HF with preserved ejection fraction (HFpEF - n = 35) and HF with reduced ejection fraction (HFrEF - n = 24). Results Patients without HF had a mean SF-36 score significantly greater than those with HF (499.8 ± 139.1 vs 445.4 ± 123.8; p = 0.008). Functional capacity - ability and difficulty to perform common activities of everyday life - was significantly worse (p < 0.0001) in patients with HF independently of sex and age. There was no difference between HFpEF and HFrEF. Conclusion Patients with HF had low quality of life regardless of the syndrome presentation (HFpEF or HFrEF phenotype). Quality of life evaluation in primary care could help identify patients who would benefit from a proactive care program with more emphasis on multidisciplinary and social support.

Prevenção da úlcera de pressão na UTI: o cuidado sob a ótica do enfermeiro

This research deals with prevention of the pressure ulcers in Intensive Care Unit, in the optics of nursing care. Research questions: Which nursing cares are undertaken by ICU nurses for preventing the pressure ulcer? How nurses understand their assistance in the pressure ulcer prevention ? Objectives: to characterize the nursing care fulfilled for nurses in the ICU related to the prevention of pressure ulcer; to discuss what nurses think about their nursing assistance for preventing pressure ulcer and to analyze the approximation and distancing extent in speech by nurses concerning prevention of pressure ulcer. This is a qualitative, descriptive and explorative study joining 08 nurses, and adopting three moments: a sensibility dynamic, with individual production, group discussion and an individual semi-structured interview. Therefore this way, it was possible to realize what and how nurses think about their participation in the prevention and appearance of pressure ulcer context in the ICU; their conflicts facing the multiprofessional responses; and the human aspects – sensible and ethics – implicated on care. Keywords: nursing; nursing care; pressure ulcer.
