The Short Physical Performance Battery is scored on a scale of 0-12, with a higher score indicating better physical function.

Evaluated by the Exercise Adherence Rating Scale (EARS)

The combined number of all-cause rehospitalizations and death 3 and 6 months after discharge.

Handgrip strength is measured in kilograms by a handgrip dynamometer.

The Fried criteria consists of 5 components: low physical activity, exhaustion, weakness, slowness, and unintentional weight loss. The presence of 3 or more Fried criteria indicates frailty, 1-2 criteria indicates pre-frailty, and 0 criteria indicates no frailty.

The EFT is scored 0 (least frail) to 5 (most frail) based on the following 4 items: pre-procedural anemia, hypoalbuminemia, lower-extremity muscle weakness defined as a time of >15 s or inability to complete five sit-to-stand repetitions without using arms. and cognitive impairment is defined as a score of <24 on the Mini-Mental State Examination (which is highly unlikely if the patient is able to correctly recall 3 out of 3 words after a distractive task and may obviate the need for further cognitive testing).

A Mini-Mental State Examination (MMSE) is a set of 11 questions that doctors and other healthcare professionals commonly use to check for cognitive impairment (problems with thinking, communication, understanding, and memory).

The EQ-5D-5L is a quality-of-life tool with 5 components designed to detect health utilities: mobility, usual activities, self-care, pain/discomfort, and anxiety/depression. All components are rated on a scale of 1-5 with higher scores indicating worse health status.

The Mini Nutritional Assessment (MNA) has recently been designed and validated to provide a single, rapid assessment of nutritional status in elderly patients in outpatient clinics, hospitals, and nursing homes. The MNA test is composed of simple measurements and brief questions that can be completed in about 10 min. The sum of the MNA score distinguishes between elderly patients with 1) adequate nutritional status, MNA > or = 24; 2) protein-calorie malnutrition, MNA < 17; 3) at risk of malnutrition, MNA between 17 and 23.5.

The Generalised Anxiety Disorder Assessment (GAD-7) is a seven-item instrument that is used to measure or assess the severity of generalised anxiety disorder (GAD). Each item asks the individual to rate the severity of his or her symptoms over the past two weeks. Response options include "not at all", "several days", "more than half the days" and "nearly every day".

The 15-item geriatric depression scale (GDS-15) is a short form of GDS and is used to screen, diagnose, and evaluate depression in elderly individuals.

The Pittsburgh Sleep Quality Index (PSQI) is a self-report questionnaire that assesses sleep quality over a 1-month time interval. The measure consists of 19 individual items, creating 7 components that produce one global score, and takes 5-10 minutes to complete.

The Duke Activity Status Index is a patient-reported estimate of functional capacity, maximal oxygen consumption (VO2 max), and maximum metabolic equivalent of tasks (METs).

Assess the economic impact of the intervention by comparing medical costs between two groups, inclusive of direct medical costs, direct non-medical costs, and the cost of rehabilitation therapy, relative to its associated changes in health outcomes.

Calculate BMI values by measuring the patient's height and weight. Weight should be in kilograms. Height should be in meters)

The unit of systolic and diastolic blood pressure should be 'mmHg'.

The data collector will measure the heart rate of the patient during each outpatient visit.

Data collectors obtain NYHA classification by reviewing medical records.

During the outpatient follow-up, the patient needs to report whether they have had the symptoms and signs in the past week: yes or no. If there are other symptoms, the patient needs to write them down in detail.

Data collectors obtain Left Ventricular Ejection Fraction (%) by reviewing medical records.

Data collectors obtain NT-proBNP and cTnT by reviewing medical records. The unit of NT-proBNP is 'pg/mL'. The unit of cTnT is 'ug/L'.

Data collectors obtain eGFR by reviewing medical records. The unit of eGFR is 'ml/min'.

Data collectors obtain TG, CHOL, LDL-C, and HDL-C by reviewing medical records. The unit of these biomarkers is 'mmol/L'.

Data collectors obtain RBC by reviewing medical records. The unit of RBC is '10^12/L'.

Data collectors obtain HGB by reviewing medical records. The unit of HGB is 'g/L'.

Data collectors obtain WBC by reviewing medical records. The unit of WBC is '10^9/L'.

Data collectors obtain PLT by reviewing medical records. The unit of PLT is '10^9/L'.

Data collectors obtain PT and APTT by reviewing medical records. The unit of PT and APTT is 's'.

The Lubben Social Network Scale-6 (LSNS-6) is a six-item, self-reported scale to assess social isolation in older adults by measuring perceived social support received by family and friends.
