Public awareness of palliative care for heart failure in Japan: A cross-sectional study

Background

Palliative care (PC) benefits cancer patients and those with heart failure (HF), improving quality of life and symptom burden. Despite guidelines recommending the integration of PC into HF care, its use remains inadequate, partly due to insufficient public awareness. This study aimed to assess the public awareness of PC for HF in Japan and identify factors associated with awareness.

Methods

A cross-sectional online survey was conducted from March 6–13, 2023, using a panel operated by Intage Inc. (Tokyo, Japan), which has a pool of 3.78 million potential Japanese respondents. The survey included 51,790 participants, matched for sex, age, and region of residence. Participants were asked about their awareness of PC eligibility for HF, along with demographic information, history of hospitalization for sudden illness, outpatient visits, and health status in the previous 2 years. The χ² test and Cramer's V were used to analyze associations between awareness and variables, and multivariate logistic regression was used to estimate awareness predictors.

Results

In total, 91 % of participants were unaware of PC eligibility for HF. Age group, healthcare professional occupation, and history of hospitalization for acute myocardial infarction, acute HF, acute pulmonary embolism, and ruptured aortic aneurysm had weak to moderate associations with awareness. Multivariate analysis revealed that a history of hospitalization for sudden cardiovascular illness and being a healthcare professional were positively related to awareness, while age, female sex, and being married were associated with lower odds of awareness.

Conclusion

The low public awareness of PC for HF in Japan underscores the importance of increasing awareness of the eligibility of PC for HF, as well as cancer, to integrate PC into HF practice as basic care.
