The study program will provide an integrated interactive digital health application (LINE app on smartphones, incorporating information about biodata recording, health education, questionnaires, and online Q&A)

The rate of heart failure re-hospitalization

The KCCQ-12 is a validated health status measure for patients with HF. It contains four subdomains: Physical Limitation, Symptom Frequency, Quality of Life, and Social Limitations. Each subdomain provides an individual score from 0 to 100, with 0 denoting the worst and 100 the best possible health status. The mean of the four subdomain scores are presented as a summary score, with differences of 5 points or greater considered to be clinically important.

The EQ-5D-5L is a widely used health status measure with two parts. The first part evaluates health across five dimensions: MOBILITY, SELF-CARE, USUAL ACTIVITIES, PAIN/DISCOMFORT, and ANXIETY/DEPRESSION, each with five response levels. This generates a health state profile, which can be assigned a summary index score based on societal preference weights, or "utilities," for calculating QALYs in health economics. Scores range from less than 0 (death or worse) to 1 (full health), with higher scores indicating better health utility. The second part of the questionnaire is a visual analogue scale (VAS) where patients rate their perceived health from 0 (worst imaginable health) to 100 (best imaginable health).

The Functional Assessment of Chronic Illness Therapy - Spiritual Well-Being (FACIT-Sp-12) is a 12-item scale designed to measure spiritual well-being in individuals with chronic illnesses. Possible scores range from 0 to 48, with higher scores reflecting greater spiritual wellbeing.
