Impact of implementing electronic clinical practice guidelines for the diagnosis, control and treatment of cardiovascular risk factors: A pre-post controlled study / Impacto de la implementación de las guías de práctica clínica electrónicas en el diagnóstico, control y tratamiento de los factores de riesgo cardiovascular: un estudio pre-post controlado

Objective: To evaluate the impact of computerized clinical practice guidelines on the management, diagnosis, treatment, control, and follow-up of the main cardiovascular risk factors: hypertension, hypercholesterolaemia, and type 2 diabetes mellitus. Design: Pre-post controlled study. Setting: Catalonia, autonomous community located in north-eastern Spain. Participants: Individuals aged 35-74 years assigned to general practitioners of the Catalan Health Institute. Intervention: The intervention group consisted of individuals whose general practitioners had accessed the computerized clinical practice guidelines at least twice a day, while the control group consisted of individuals whose general practitioner had never accessed the computerized clinical practice guidelines platform Main outcomes: The Chi-squared test was used to detect significant differences in the follow-up, control, and treatment variables for all three disorders (hypertension, hypercholesterolaemia, and type 2 diabetes mellitus) between individuals assigned to users and non-users of the computerized clinical practice guidelines, respectively. Results: A total of 189,067 patients were included in this study, with a mean age of 56 years (standard deviation 12), and 55.5% of whom were women. Significant differences were observed in hypertension management, treatment and control; type 2 diabetes mellitus management, treatment and diagnoses, and the management and control of hypercholesterolaemia in both sexes. Conclusions: Computerized clinical practice guidelines are an effective tool for the control and follow-up of patients diagnosed with hypertension, type 2 diabetes mellitus, and hypercholesterolaemia. The usefulness of computerized clinical practice guidelines to diagnose and adequately treat individuals with these disorders remains unclear (AU)

Ischemic aetiology, self-reported frailty, and gender with respect to cognitive impairment in chronic heart failure patients.

BACKGROUND: Decisive information on the parameters involved in cognitive impairment in patients with chronic heart failure is as yet lacking. Our aim was to determine the functional and psychosocial variables related with cognitive impairment using the mini-mental-state examination (MMSE) with age-and education-corrected scores. METHODS: A cohort study of chronic heart failure patients included in an integrated multidisciplinary hospital/primary care program. The MMSE (corrected for age and education in the Spanish population) was administered at enrolment in the program. Analyses were performed in 525 patients. Demographic and clinical variables were collected. Comprehensive assessment included depression (Yesavage), family function (family APGAR), social network (Duke), dependence (Barthel Index), frailty (Barber), and comorbidities. Univariate and multivariate logistic regression were performed to determine the predictors of cognitive impairment. RESULTS: Cognitive impairment affected 145 patients (27.6 %). Explanatory factors were gender (OR: 2.77 (1.75-4.39) p < 0.001), ischemic etiology (OR: 1.99 (1.25-3.17) p = 0.004), frailty (OR: 1.58 (0.99 to 2.50, p =0.050), albumin > 3.5 (OR: 0.59 (0.35-0.99) p = 0.048), and beta-blocker treatment (OR: 0.36 (0.17 to 0.76, p = 0.007)). No association was found between cognitive impairment and social support or family function. CONCLUSION: The observed prevalence of cognitive impairment using MMSE corrected scores was 27.6 %. A global approach in the management of these patients is needed, especially focusing on women and patients with frailty, low albumin levels, and ischemic aetiology heart failure.

Impact on clinical events and healthcare costs of adding telemedicine to multidisciplinary disease management programmes for heart failure: Results of a randomized controlled trial.

BACKGROUND: The role of telemedicine in the management of patients with chronic heart failure (HF) has not been fully elucidated. We hypothesized that multidisciplinary comprehensive HF care could achieve better results when it is delivered using telemedicine. METHODS AND RESULTS: In this study, 178 eligible patients with HF were randomized to either structured follow-up on the basis of face-to-face encounters (control group, 97 patients) or delivering health care using telemedicine (81 patients). Telemedicine included daily signs and symptoms based on telemonitoring and structured follow-up by means of video or audio-conference. The primary end-point was non-fatal HF events after six months of follow-up. The median age of the patients was 77 years, 41% were female, and 25% were frail patients. The hazard ratio for the primary end-point was 0.35 (95% confidence interval (CI), 0.20-0.59; p-value < 0.001) in favour of telemedicine. HF readmission (hazard ratio 0.39 (0.19-0.77); p-value=0.007) and cardiovascular readmission (hazard ratio 0.43 (0.23-0.80); p-value=0.008) were also reduced in the telemedicine group. Mortality was similar in both groups (telemedicine: 6.2% vs control: 12.4%, p-value > 0.05). The telemedicine group experienced a significant mean net reduction in direct hospital costs of €3546 per patient per six months of follow-up. CONCLUSIONS: Among patients managed in the setting of a comprehensive HF programme, the addition of telemedicine may result in better outcomes and reduction of costs.

Fiber intake and all-cause mortality in the Prevención con Dieta Mediterránea (PREDIMED) study.

BACKGROUND: Few observational studies have examined the effect of dietary fiber intake and fruit and vegetable consumption on total mortality and have reported inconsistent results. All of the studies have been conducted in the general population and typically used only a single assessment of diet. OBJECTIVE: We investigated the association of fiber intake and whole-grain, fruit, and vegetable consumption with all-cause mortality in a Mediterranean cohort of elderly adults at high cardiovascular disease (CVD) risk by using repeated measurements of dietary information and taking into account the effect of a dietary intervention. DESIGN: We followed up 7216 men (55-75 y old) and women (60-75 y old) at high CVD risk in the Prevención con Dieta Mediterránea (PREDIMED) trial for a mean of 5.9 y. Data were analyzed as an observational cohort. Participants were initially free of CVD. A 137-item validated food-frequency questionnaire administered by dietitians was repeated annually to assess dietary exposures (fiber, fruit, vegetable, and whole-grain intakes). Deaths were identified through the continuing medical care of participants and the National Death Index. An independent, blinded Event Adjudication Committee adjudicated causes of death. Cox regression models were used to estimate HRs of death during follow-up according to baseline dietary exposures and their yearly updated changes. RESULTS: In up to 8.7 y of follow-up, 425 participants died. Baseline fiber intake and fruit consumption were significantly associated with lower risk of death [HRs for the fifth compared with the first quintile: 0.63 (95% CI: 0.46, 0.86; P = 0.015) and 0.59 (95% CI: 0.42, 0.82; P = 0.004), respectively]. When the updated dietary information was considered, participants with fruit consumption >210 g/d had 41% lower risk of all-cause mortality (HR: 0.59; 95% CI: 0.44, 0.78). Associations were strongest for CVD mortality than other causes of death. CONCLUSION: Fiber and fruit intakes are associated with a reduction in total mortality. PREDIMED was registered at controlled-trials.com as ISRCTN35739639.

Prescription in patients with chronic heart failure and multimorbidity attended in primary care.

BACKGROUND: Multimorbidity and polypharmacy pose challenges to improving the quality of care. OBJECTIVES: To determine the association between prescription of recommended treatment in ambulatory patients with chronic heart failure and multiple comorbidities and hospitalisation events. DESIGN: A population-based retrospective cohort study in Catalonia (north-east Spain). PARTICIPANTS: We included 7173 newly registered patients with chronic heart failure (59% women; mean [SD] age 76.3 [10.7] years). Patients were selected from the electronic patient records of primary care practices and followed for three years. OUTCOME MEASURES: Prescription of angiotensin-converting enzyme inhibitors (ACEIs), angiotensin II receptor blockers (ARBs) and beta-blockers (BBs). RESULTS: Prescription of ACEI/ARBs in patients managed in primary care without a hospitalisation event during the follow-up rose from 50.8 to 83.5% for 0 and ≥4 comorbidities, respectively, and for ACEI/ARBs and BB from 13.1 to 30.6% for 0 and ≥4 comorbidities respectively. Patients with a hospitalisation event were treated more often (ACEI/ARBs or 1.47 [1.17 to 1.85]; ACEI/ARBs and BB or 1.41 [1.17 to 1.69]). Comorbid conditions receiving more treatment were hypertension (ACEI/ARBs or 3.75 [3.33 to 4.22]; ACEI/ARBs and BB or 1.40 [1.23 to 1.59]), diabetes mellitus (ACEI/ARBs or 1.79 [1.57 to 2.04]; ACEI/ARBs and BB or 1.33 [1.18 to 1.49]) and ischaemic heart disease (ACEI/ARBs or 1.25 [1.10 to 1.42]; ACEI/ARBs and BB or 3.01 [2.68 to 3.38]). CONCLUSION: Prescription of recommended treatment in patients with chronic heart failure increased as the number of comorbidities increased. Family physicians can provide equivalent care to more complex patients and those less complex, according to the number of comorbidities.

Supervivencia de pacientes ambulatorios con insuficiencia cardiaca crónica del área mediterránea. Un estudio de base poblacional / Survival in mediterranean ambulatory patients with chronic heart failure. A population-based study

Introducción y objetivos. La investigación realizada en pacientes ambulatorios con insuficiencia cardiaca crónica en el área mediterránea es escasa. Nuestro objetivo es describir las tendencias de supervivencia en nuestra población diana y la influencia de los factores pronósticos. Métodos. Llevamos a cabo un estudio de cohorte retrospectivo de base poblacional en Cataluña sobre 5.659 pacientes ambulatorios (el 60% de mujeres; media de edad, 77 ± 10 años) con insuficiencia cardiaca crónica incidente. Se seleccionó a los pacientes elegibles a partir de los registros electrónicos de historias clínicas de centros de atención primaria de 2005 y se realizó un seguimiento hasta 2007. Resultados. Durante el periodo de seguimiento, se produjo la muerte de 950 pacientes (16,8%). La supervivencia tras el inicio de la insuficiencia cardiaca crónica, al cabo de 1, 2 y 3 años, fue del 90, el 80 y el 69% respectivamente. No hubo diferencias significativas de supervivencia entre varones y mujeres (p = 0,13). El modelo de riesgos proporcionales de Cox confirmó un aumento del riesgo de muerte con el avance de la edad (razón de riesgos = 1,06; intervalo de confianza del 95%, 1,06-1,07), diabetes mellitus (razón de riesgos = 1,53; intervalo de confianza del 95%, 1,33-1,76), enfermedad renal crónica (razón de riesgos = 1,73; intervalo de confianza del 95%, 1,45-2,05) y cardiopatía isquémica (razón de riesgos = 1,18; intervalo de confianza del 95%, 1,02-1,36). La hipertensión (razón de riesgos = 0,73; intervalo de confianza del 95%, 0,64-0,84) tuvo un efecto protector. Conclusiones. Los programas de planificación de servicios y de prevención deben tener en cuenta las tasas de supervivencia relativamente elevadas que se observan en nuestra área y el efecto de los factores pronósticos que pueden ser útiles para identificar a los pacientes de alto riesgo (AU)

Introduction and objectives. Scarce research has been performed in ambulatory patients with chronic heart failure in the Mediterranean area. Our aim was to describe survival trends in our target population and the impact of prognostic factors. Methods. We carried out a population-based retrospective cohort study in Catalonia (north-east Spain) of 5659 ambulatory patients (60% women; mean age 77 [10] years) with incident chronic heart failure. Eligible patients were selected from the electronic patient records of primary care practices from 2005 and were followed-up until 2007. Results. During the follow-up period deaths occurred in 950 patients (16.8%). Survival after the onset of chronic heart failure at 1, 2, and 3 years was 90%, 80%, 69%, respectively. No significant differences in survival were found between men and women (P=.13). Cox proportional hazard modelling confirmed an increased risk of death with older age (hazard ratio=1.06; 95% confidence interval, 1.06-1.07), diabetes mellitus (hazard ratio=1.53; 95% confidence interval, 1.33-1.76), chronic kidney disease (hazard ratio=1.73; 95% confidence interval, 1.45-2.05), and ischemic heart disease (hazard ratio=1.18; 95% confidence interval, 1.02-1.36). Hypertension (hazard ratio=0.73; 95% confidence interval, 0.64-0.84) had a protective effect. Conclusions. Service planning and prevention programs should take into consideration the relatively high survival rates found in our area and the effect of prognostic factors that can help to identify high risk patients (AU)

Beta-blocker treatment of stable heart failure in primary care.

INTRODUCTION AND OBJECTIVES: Beta-blocker treatment of stable heart failure in primary care. The objective was to evaluate the feasibility and tolerability of uptitrating beta-blockers in patients with stable systolic heart failure seen in primary care. METHODS: Before and after intervention study. The study was conducted in two primary care centers in Barcelona, Spain. Consecutive samples of patients with systolic heart failure who had not received previous beta-blocker treatment were recruited between April 2004 and April 2006. Treatment was started with the lowest dose of bisoprolol or carvedilol and the dose was doubled every two weeks in the absence of contraindications. Patients were followed up for 6 months. RESULTS: The study included 88 patients (76.1% male, 23,9% female, mean age 64.88 years). Of these, 57.1% were treated with bisoprolol and 42.9% with carvedilol. Overall, 75.0% reached the target dose, 21.7% tolerated a dose lower than the target dose, and 3.3% had the beta-blocker withdrawn (due to bradycardia in 1.1%, syncope in 1.1%, and stroke in 1.1%). Adverse events were experienced by 70.4%, the majority of which (57.95%) were resolved without changing treatment. The most common were nausea (42.04%), asthenia (35.22%), and increased dyspnea (17.04%). There were significant improvements in functional class and ejection fraction. CONCLUSIONS: The majority of adverse events were mild. Treatment was withdrawn in only a few patients and most reached the recommended target dose. Appropriately trained primary care physicians can uptitrate beta-blockers in heart failure patients without undue concern.
