目的：心血管疾病（CVD）是21世紀重要的慢性健康問題，它同時為台灣及世界各地的經濟與生活習慣帶來了相當大挑戰，本研究為應用LINE@對CVD患者進行遠距健康照護之可行性與效益評估。方法：研究對象為經由SF-36（Short Form-36）問卷量表評估之心臟內科門診追蹤的出院病患，且依照其參與LINE@ 的意願分為實驗組（n = 26）與對照組（n =55）。結果：參與者平均年齡64.58 ± 11.02歲且男性佔65.43%；實驗組65歲以下佔61.50%，對照組佔45.50%；研究顯示年齡影響參與意願；同時，SF-36量表中的生理功能較佳者，使用LINE@意願較高（P ＜ 0.01）；肝功能輕度異常者意願也較高（P = 0.02）。結論：應用LINE@做為遠距健康照護工具以傳遞衛教訊息具有可行性。生理功能較佳者、或肝功能輕度上升者參與意願較高；而年長者使用意願較低，建議結合科技應用的遠距照護需考量高齡使用者介面設計。

Objectives: Cardiovascular disease (CVD) remains a significant chronic healthcare problem in this 21st century, with considerable associated economic and quality-of-life challenges worldwide and in Taiwan and worldwide. The aim of this study is was to determine the acceptability of telehealth care and whether or not telehealth care is helpful for CVD patients using the new communication application, LINE@. Methods: Consecutive post-discharge CVD patients were enrolled. All participants were evaluated by SF-36 questionnaire scale, and divided into two groups by their willingness. LINE @ system provided daily automatic reminders including blood pressure recording and health education information (n = 26) and the control group relied on self-management without reminders (n = 55). Results: The mean age was 64.58 ± 11.02 years and 65.43% were male. Age seems to affected the willingness to accept telehealth care;. subjects younger than 65 years in the experimental group were 61.50%, while only 45.50% in control group. The higher physical functioning scales were significantly associated with intention to use telehealth care system (P ＜ 0.01). On the other hand, subjects with mildly abnormal liver function were more willing to participate in LINE @ (P = 0.02). Conclusions: This pilot study demonstrated the feasibility of message reminders using LINE @ in post-discharge care. Patients who had the subjectively better physical function or mild elevation of GPT were more willing to join LINE@; while elderly subjects had lower motivation to join LINE @. There is substantial room for improvement for telehealth care, such as friendly designed user interfaces, especially for the elderly.
