Efficacy of a Strategy for Implementing Guidelines for the Control of Cardiovascular Risk in Primary Healthcare

Background: A number of strategies exist for the implementation of clinical practice guides (CPGs). Aim: To assess the efficacy of implementing a cardiovascular risk CPG based on an educational method involving opinion leaders, and the habitual method of dissemination among primary healthcare teams. Design and Setting: Controlled, blinded, community intervention trial randomised by clusters. Methods: 21 primary healthcare centres were randomly assigned to either the intervention arm (n = 11) or the control arm (n = 10). The study subjects were patients aged ≥45 years assigned to the centres. The overall impact of the intervention was measured as the difference between the increase in the proportion of patients whose medical records showed the recording of all the variables necessary to calculate cardiovascular risk in both arms. Analyses were performed with Generalized Lineal Model on an intention-to-treat basis. Results: 917 subjects were included at the beginning of the trial (437 in the intervention arm and 480 in the control arm). 826 subjects were included in the final evaluation (436 in the intervention group and 390 in the control arm). At the end of the trial, the recording of the variables necessary for the calculation of the cardiovascular risk in the intervention group had increased more than in the control group (difference between increases 7.49% (95% CI 4.62 - 10.35)) after adjusting for confounding variables. Conclusions: Compared to the habitual method of dissemination, the implementation of this CPG using an educational method involving opinion leaders, improved the recording of the variables needed to calculate patients’ cardiovascular risk.Funding for the trial was provided by the Plan Nacional de Investigación Científica, Desarrollo e Innovación Tecnológica (I+D+I).

Riesgo cardiovascular en la población anciana española: escala de riesgo EPICARDIAN

[Abstract] Background and objectives: Cardiovascular risk estimation in people over 70 years of age is problematic. Most scores have been created based on cohorts of middle-aged people, with an underrepresentation of older adults. The predictive power of classical cardiovascular risk factors declines with age. The aim of this work is to develop a specific score for estimating cardiovascular risk among the elderly population in Spain. Methods: This work is a population-based cohort established in 1995. Setting: Three geographical areas of Spain (Madrid, Ávila, and Lugo). Participants: 3,729 people older than 64 years with no cardiovascular diseases (CVD) at baseline. Measurements: Suspected fatal and nonfatal CVD (both coronary heart disease and stroke) were investigated annually and confirmed using the WHO-MONICA criteria. All participants were followed-up on until occurrence of a first CVD event, until death, or until December 31, 2015. Results: Age was the strongest predictor of CVD at 10 years in both men and women. In men, variables associated with CVD were high blood pressure treatment (HR: 1.35; 95% CI: 1.067-1.710), diabetes (HR: 1.359; 95% CI: 0.997-1.852), and smoking (HR: 1.207; 95% CI: 0.945-1.541) and in women, the variables were smoking (HR: 1.881; 95% CI: 1.356-2.609) and diabetes (HR: 1.285; 95% CI: 0.967-1.707). Total cholesterol did not increase the risk of CVD in men or women. However, total cholesterol levels >200 mg/dL were inversely associated with 10-year risk of CVD in men and women. Conclusions: In elderly Spanish men, total CVD at 10 years is significantly increased by age, diabetes, and antihypertensive treatment and in elderly Spanish women by diabetes and smoking. Total cholesterol levels did not increase the risk of CVD, particularly in males.[Resumen] Antecedentes y objetivos. La estimación del riesgo cardiovascular en personas mayores de 70 años es problemática. La mayoría de las escalas se han creado basándose en cohortes de personas de mediana edad, con una representación insuficiente de los adultos de más edad. El poder predictivo de los factores de riesgo cardiovascular clásicos disminuye con la edad. El objetivo de este estudio es desarrollar una escala específica para estimar el riesgo cardiovascular de la población anciana española. Métodos. Este estudio se realizó en una cohorte poblacional establecida en 1995. Marco: tres zonas geográficas de España (Madrid, Ávila y Lugo). Participantes: 3.729 personas mayores de 64 años sin enfermedades cardiovasculares (ECV) al inicio del seguimiento. Mediciones: Se investigaron anualmente las sospechas de ECV mortal y no mortal (cardiopatía coronaria e ictus) y se confirmaron usando los criterios del proyecto MONICA de la OMS. Se siguió a todos los participantes hasta que apareció el primer episodio de ECV, hasta su muerte o hasta el 31 de diciembre de 2015. Resultados. La edad fue el factor predictivo más potente de ECV a los 10 años en ambos sexos. Las variables asociadas con ECV en los varones fueron el tratamiento de la hipertensión arterial (HR: 1,35; IC al 95%: 1,067−1,710), la diabetes (HR: 1,359; IC al 95%: 0,997−1,852) y el tabaquismo (HR: 1,207; IC al 95%: 0,945−1,541) y en las mujeres, el tabaquismo (HR: 1,881; IC al 95%: 1,356−2,609) y la diabetes (HR: 1,285; IC al 95%: 0,967−1,707). El colesterol-total no aumentó el riesgo de ECV, ni en varones ni en mujeres. Sin embargo, las concentraciones de colesterol total > 200 mg/dL se asociaron inversamente al riesgo de ECV a los 10 años, tanto en varones como en mujeres. Conclusiones. La ECV total a los 10 años aumenta significativamente en los varones españoles de edad avanzada con la edad, la diabetes y el tratamiento antihipertensivo y en las mujeres con la diabetes y el tabaquismo. Los niveles de colesterol total no aumentaron el riesgo de ECV, sobre todo en los varones.Instituto de Salud Carlos III; FIS 93/012Instituto de Salud Carlos III; FIS 96/1993Instituto de Salud Carlos III; FIS 02/0896Ministerio de Economía y Competitividad (España); PB/255-Co

Estudios descriptivos de parasuicido en urgencias psiquiátricas.

El parasuicidio supone un importante problema de salud pública, tanto por su elevada incidencia como por las importantes consecuencias a nivel médico y social. La forma habitual de abordar este problema es a través del estudio de las características del paciente parasuicida y del intento de suicidio. Nuestro estudio se compone de una muestra de 184 pacientes atendidos por parasuicidio. Se han valorado características sociodemográficas, clínicas y psicosociales del paciente, así como las características del parasuicidio, sus repercusiones médicas y el grado de intencionalidad suicida. El perfil del paciente fue el de una mujer soltera, de 36´7 años de media, que convive con otras personas y está en paro. Más de la mitad de la muestra estaba ya en tratamiento psiquiátrico, siendo el diagnóstico más frecuente el de trastorno de personalidad. El método más usado fue el de ingestión de psicofármacos, benzodiacepinas y antidepresivos fundamentalmente. El 20% requirió ingreso hospitalario y el 50% fue derivado al Centro de Salud Mental para seguimiento. Respecto a la intencionalidad, se hallaron 2 subgrupos con diferentes frecuencia, diagnóstico, pronóstico y tratamiento

Effect of oral nitrates on pulse pressure and arterial elasticity in patients aged over 65 years with refractory isolated systolic hypertension: study protocol for a randomized controlled trial

BACKGROUND: Isolated systolic hypertension is a highly prevalent disease among the elderly. The little available evidence on the efficacy of nitrates for treating the disease is based on small experimental studies. METHODS/DESIGN: We performed a multicenter, randomized, double-blind, phase III, placebo-controlled trial in 154 patients aged over 65 years with refractory isolated systolic hypertension. Patients were randomized to placebo or 40 mg/day of extended-release isosorbide mononitrate added to standard therapy and titrated to 60 mg/day at week 6 if blood pressure exceeded 140/90 mmHg.The primary objective was to assess the effect on clinical pulse pressure of extended-release isosorbide mononitrate added to standard therapy in patients aged over 65 years with refractory isolated systolic hypertension after 3 months of treatment.The secondary objectives were as follows: to quantify the effect of adding the study drug on central blood pressure and vascular compliance using the augmentation index and pulse wave velocity; to evaluate the safety profile by recording adverse effects (frequency, type, severity) and the percentage of patients who had to withdraw from the trial because of adverse events; to quantify the percentage of patients who reach a clinical systolic blood pressure <140 mmHg or <130 mmHg measured by ambulatory blood pressure monitoring; and to quantify the change in pulse pressure measured by ambulatory blood pressure monitoring. DISCUSSION: Few clinical trials have been carried out to test the effect of oral nitrates on isolated systolic hypertension, even though these agents seem to be effective. Treatment with extended-release isosorbide mononitrate could improve control of systolic blood pressure without severe side effects, thus helping to reduce the morbidity and mortality of the disease.

Development and validation of a risk stratification model for prediction of disability and hospitalisation in patients with heart failure: a study protocol

BACKGROUND: Chronic heart failure (CHF) reduces quality of life and causes hospitalisation and death. Identifying predictive factors of such events may help change the natural history of this condition. AIM: To develop and validate a stratification system for classifying patients with CHF, according to their degree of disability and need for hospitalisation due to any unscheduled cause, over a period of 1 year. METHODS AND ANALYSIS: Prospective, concurrent, cohort-type study in two towns in the Madrid autonomous region having a combined population of 1 32 851. The study will include patients aged over 18 years who meet the following diagnostic criteria: symptoms and typical signs of CHF (Framingham criteria) and left ventricular ejection fraction (EF)50%).Outcome variables will be(a) Disability, as measured by the WHO Disability Assessment Schedule V.2.0 Questionnaire, and (b) unscheduled hospitalisations. The estimated sample size is 557 patients, 371 for predictive model development (development cohort) and 186 for validation purposes (validation cohort). Predictive models of disability or hospitalisation will be constructed using logistic regression techniques. The resulting model(s) will be validated by estimating the probability of outcomes of interest for each individual included in the validation cohort. ETHICS AND DISSEMINATION: The study protocol has been approved by the Clinical Research Ethics Committee of La Princesa University Teaching Hospital (PI-705). All results will be published in a peer-reviewed journal and shared with the medical community at conferences and scientific meetings.This study was funded by Health Research Fund (Fondo de InvestigacionesSanitarias/FIS) grant no. PI 14/01677 and co-financed with European Regional Development Fund (ERDF) funds (Carlos III Institute of Health-Research Network for Chronic Diseases/ISCIII–REDISSEC Project).S
