The goal of this clinical trial is to learn if a structured tele-consultation program, delivered 3 times over 12 weeks, can improve (reverse) frailty in geriatric patients recently discharged from the hospital. The main questions it aims to answer are:
* Does structured tele-consultation covering physical exercise, nutrition, and home care education change health behavior in older adults after hospital discharge?
* Does this change in health behavior lead to improvement in frailty, as measured by Clinical Frailty Scale (CFS) score?
* Does this change in health behavior lead to improvement in frailty, as measured by decreased interleukin-6 (IL-6) and myostatin levels and increased albumin levels?
* Does this change in health behavior lead to improvement in frailty, as measured by increased hand grip strength?
Researchers will compare participants receiving structured tele-consultation (delivered 3 times over 12 weeks) to participants receiving usual care to see if tele-consultation leads to greater improvement in health behavior and frailty status.
Participants will:
* Undergo baseline assessment of CFS score, hand grip strength, and blood sampling for IL-6, albumin, and myostatin shortly after hospital discharge
* Be randomly assigned to receive either structured tele-consultation (3 sessions over 12 weeks, covering physical exercise, nutrition, and home care education) or usual care
* Undergo repeat assessment of health behavior, CFS score, hand grip strength, and the same blood markers at the end of the 12-week period
