Study of the Quality of Medical Therapy and Adherence in Patients with Chronic Heart Failure (According to the COMPLIANCE Study)

Aim. Assess the medical therapy quality in patients with chronic heart failure (CHF) and patients' adherence to the treatment depending on the previous observation in a specialized medical center as part of an of an outpatient registry.Materials and methods. An analysis of the medical therapy quality in patients with CHF was carried out as part of the COMPLIANCE prospective observational study (NCT04262583). 72 patients with CHF verified according to the protocol were included in the study. The average age of the patients was 69.1±9.5 years (31% of women and 69% of men). Patients were divided into groups: those who first applied to a specialized department during the period of the study inclusion, or those who were previously observed in a specialized department. The general adherence assessment to medical therapy was carried out using the original questionnaire «The adherence scale of the National Society for Evidence-Based Pharmacotherapy» which was supplemented with questions to assess the actual adherence to specific medical drugs recommended for patients with CHF.Results. According to the results of the study, beta-blockers were prescribed to 70 (97.2%) patients. Angiotensin converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARBs) were recommended in 68 (94%) patients. Mineralocorticoid receptor antagonists were included in therapy in 6 out of 9 patients who were shown to be prescribed (66.6%). The choice of medical drugs within the group was not always adequate. For example, ACEi/ARBs with proven efficacy in patients with CHF were prescribed only in 72% of patients. Comparative analysis of adherence to medical therapy between patients of the selected groups demonstrated a higher adherence to the recommended therapy in patients who were previously observed in a specialized center.Conclusion. The medical therapy quality for patients with CHF doesn't always comply with current clinical guidelines. The choice of a medical drug within a group is not always adequate. Regular observation in a specialized center contributes to a higher adherence to the recommended therapy.

Abstract BackgroundAdherence to guideline-directed medical therapy (GDMT) remains low particularly in elderly despite several approaches. Previous studies showed that heart failure (HF) patients who receive pharmacist-involved multidisciplinary care may have better clinical outcomes. We evaluated patient characteristics and the practice of receiving individual GDMT in chronic HF patients who attended multidisciplinary clinics.MethodsA retrospective audit of data of chronic HF patients presenting to two multidisciplinary outpatient clinics at a tertiary hospital between March 2005 and January 2017 was performed. Data were obtained from two clinics, a Multidisciplinary Ambulatory Consulting Service (MACS) clinic which uses a pharmacist-involved model of multidisciplinary care, and a General Cardiology Heart Failure Service (GCHFS) clinic which does not have the active involvement of a pharmacist.ResultsHF with mid-range ejection fraction (HFmrEF) subjects resembled the HF with preserved ejection fraction (HFpEF) patients in terms of age, heart rate (HR), systolic blood pressure (SBP) and having higher prevalence of polypharmacy whereas resembled with the HF with reduced ejection fraction (HFrEF) for the proportion of male distribution and prevalence of ischemic heart disease (IHD). Both the clinics had similar prescribing rates of GDMT and achieved maximal tolerated doses of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARB) in HFrEF, but significantly higher prescription of ACEIs/ARBs (70.5% v. 56.2%) was found in HFpEF patients in the MACS clinic. There was significantly lower rates of β-blockers and mineralocorticoid receptor antagonists (MRAs) prescription in HFrEF and HFpEF patients in both clinics. Use of digoxin in chronic atrial fibrillation (AF) was significantly higher in HFrEF patients (82.5% v. 58.5%), but number of people anticoagulated in presence of AF and prescription of diuretics were significantly lowered in MACS clinic in HFpEF patients. Age, anemia, chronic renal failure, SBP, HR and comorbidities were the significant predictors in a multivariate binary logistic regression for the utilization of GDMT.ConclusionsOur study concludes that pharmacist is an important member of a multidisciplinary team in the management of chronic heart failure. The other roles of the pharmacist within a multidisciplinary team, including continuity of care, medication compliance and prevention of adverse reactions need further research.
