Frailty, health literacy and self-care in patients admitted with acute heart failure.

BACKGROUND: There is limited knowledge from Norway on clinical characteristics, self-care and health literacy in patients admitted to hospital with acute heart failure. Our aim was to identify these factors in this group.

MATERIAL AND METHOD: We included patients admitted with acute heart failure over a period of six months (2022/2023) at Drammen Hospital and Vestfold Hospital Trust. Cardiac nurses collected information from the patients, including self-assessed knowledge on an ordinal scale from 0 (little knowledge) to 10 (good knowledge). Clinical frailty scores were calculated and data from the hospital records were recorded.

RESULTS: Of 136 patients with acute heart failure, 81 were included. Median age was 79 (range 35-95) years, 35 (43 %) were women. A total of 35 (43 %) had been admitted with heart failure exacerbation in the past year. The patients had a median of 5 (1-10) diagnoses, and the median score on the clinical frailty scale was 4 (1-7), corresponding to 'vulnerable'. A total of 63 (78 %) had been diagnosed with heart failure before admission to hospital. Of these, 13 (21 %) were unaware of the diagnosis, and their self-assessed knowledge was median 3 (25th and 75th percentile, 0-5) for management of heart failure, 2 (25th and 75th percentile, 0-5) for lifestyle interventions and 0 (25th and 75th percentile, 0-2) for heart medications. Altogether 42 out of 63 (67 %) weighed themselves weekly, 13 (21 %) measured their blood pressure, while 3 (5 %) had a self-care plan. Of 50 patients with left ventricle ejection fraction ≤ 40 %, 32 (64 %) were discharged with betablockers and angiotensin II receptor blockers or a combination drug with a neprilysin inhibitor, whereas 11 (22 %) were also prescribed SGLT2 inhibitors and mineralocorticoid receptor antagonists.

INTERPRETATION: The included patients were multimorbid and had a low level of self-care and health literacy. There is potential to optimise well-documented medicinal treatment.
