Assessment of Patient Knowledge, Awareness, and Adherence in Heart Failure in a Real-Life Setting: Insights from Data Acquired in Pharmacies

Background: Patient knowledge is crucial for managing and/or monitoring patients with heart failure (HF). However, “real-life” evidence of knowledge level and awareness in HF is yet to be explored. We assessed unselected HF patients’ knowledge and awareness in a pharmacy setting. Methods: One hundred eight HF patients (mean age [SD], 70 (12) years, 61% men) were studied in pharmacies in the north-east region of France in 2019. All patients were interviewed by their pharmacist to quantify their knowledge in HF, self-assessment of symptoms of congestion, as well as their adherence to HF treatment and guideline-recommended lifestyle. Results: Overall, 40% of patients had not consulted their cardiologist in the past 6 months, and 89% never underwent an HF education program. Regarding HF knowledge, nearly half were unsure whether they had HF (43.5%). Only half of the patients knew how to self-assess HF symptoms (57.4%), while a quarter (25%) were unsure of the purpose of HF medications. Conclusions: In patients with HF assessed in their pharmacies, a majority lacked fundamental knowledge regarding HF, such as self-assessment of congestion, possibly due to a minimal proportion of patients undergoing an HF education program. These results suggest that interventions led by pharmacies may help improve HF education coverage in patients who may have poor access to specialized care.
