According to the ongoing observational studies and the Chinese Medicine practice guideline for COVID-19 patients, the discharged patients with COVID-19 still exhibits certain clinical symptoms such as fatigue, poor appetite, short of breath, palpation, and poor sleep, which could be recognized as two main Patterns in Chinese Medicine, Qi Deficiency of Lung and Spleen and Qi & Yin Deficiency. Based on this, pulmonary rehabilitation to improve lung function upon discharged was proposed. Therefore, even patients with COVID-19 were discharged from hospitals, there are symptoms with significant clinical syndromes in Chinese Medicine perspectives. These symptoms, in terms of syndrome, which could link with the body constitutions, could be due to pre-COVID-19 infection, suffering from infection, or a consequence of post-infection.
This observational study is a rehabilitation programme to elucidate i) whether body constitution is linking with the infection of COVID-19; ii) whether TCM can help the recovery of discharged COVID-19 patients.
This is an observational multi-centered study that will be conducted in the government subsidized tri-partite CM out-patient clinics (Chinese Medicine Clinic cum Training and Research Centres, "CMCTRs").
The study contains two parts as follows:
Clinical CM Diagnostic Pattern & clinical characteristics assessments, lung function tests, quality of life and no. of western medical consultations will be assessed at each visit for 9 months. Both retrospective and prospective assessments will be done for those participants who have already joined the Rehabilitation Program in CMCTRs.
Sample Size: Estimated at 150 participants.
Treatment of the Rehabilitation Program in CMCTRs:
The treatment is based on individual Chinese Medicine syndrome and clinical symptoms based on the Chinese Medicine practice guideline for COVID-19 patients. Two main Chinese medicine syndromes for patients recovered from COVID-19 with the recommended prescriptions will be included in the Rehabilitation Program.
the participants will receive three months individualized-Chinese herbal medicine treatment in CMCTRs. After the three months treatment, they are free to either continue another three-month treatment or enter into the follow-up period. Each participant will be assessed every month during the treatment and three months after treatment as follow-up.

| Blood Pressure in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participant's blood pressure (Systolic/Diastolic) in mmHg will be recorded before and after 6MWT on each visit. | 9 months |
| Pulse in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participant's pulse (beats per minute) will be recorded before and after 6MWT on each visit. | 9 months |
| SpO2 in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participant's SpO2 (%) will be recorded before and after 6MWT on each visit. | 9 months |
| Distance Walked in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participant's distance walked (m) will be recorded during 6MWT on each visit. | 9 months |
| Number of Rests in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participant's number of rests (number) will be recorded during 6MWT on each visit. | 9 months |
| MRC Dyspnoea Scale in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participants' lung function will be assessed using MRC Dyspnoea Scale during 6MWT on each visit, for grading the effect of breathlessness on daily activities. This scale measures perceived respiratory disability and allows the patients to indicate the extent to which their breathlessness affects their mobility. The 1-5 grade scale is used alongside the questionnaire to establish the degree of breathlessness related to activity. | 9 months |
| Borg Scale of Perceived Exertion in 6-minute Walk Test (6MWT) | The six-minute walk test (6MWT) measures the distance the participant is able to walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes. The individual is allowed to self-pace and rest as needed as they traverse back and forth along a marked walkway. Participants' Borg Scale of Perceived Exertion ("Borg Score") will be recorded, by asking the participants to rate their exertion on the scale, taking into consideration feelings of physical stress and fatigue focusing on the whole feeling of exertion during 6MWT. Scoring used in Borg RPE: 6=No exertion 7-8=Extremely light 9-10=Very light 11-12=Light 13-14=Somewhat hard 15-16=Hard 17-18=Very hard 19=Extremely hard 20=Maximal exertion | 9 months |
| Peak Expiratory Flow (PEF) in Spirometry Assessment | Peak Expiratory Flow (PEF) in litres per second (L/S) is recorded in Spirometry Assessment on each visit to determine participants' lung functionality. Peak flow readings are higher when patients are well, and lower when the airways are constricted. | 9 months |
| Forced Expiratory Volume in 1 second (FEV1) in Spirometry Assessment | Forced expiratory volume in 1 second (FEV1) in Litres (L) is recorded in Spirometry Assessment on each visit to determine participants' lung functionality by assessing how much air the participants can force from their lungs in one second. Lower FEV-1 readings indicate more significant obstruction. | 9 months |
| Force Vital Capacity (FVC) in Spirometry Assessment | Force vital capacity (FVC) in Litres (L) is recorded in Spirometry Assessment on each visit to determine participants' lung functionality by assessing the largest amount of air that the participants can forcefully exhale after breathing in as deeply as they can. A lower than normal FVC reading indicates restricted breathing. | 9 months |
| FEV1/FVC ratio (%) in Spirometry Assessment | FEV1 and FVC recorded will be used to calculate the FEV1/FVC ratio (FEV1%) which is the ratio of FEV1 to FVC. In healthy adults this should be approximately 70-80% (declining with age). In obstructive diseases (asthma, COPD, chronic bronchitis, emphysema) FEV1 is diminished because of increased airway resistance to expiratory flow. FEV1% of the participants are recorded during each visit, to assess any increased airway resistance to expiratory flow. In restrictive diseases (such as pulmonary fibrosis) the FEV1 and FVC are both reduced proportionally and the value may be normal or even increased as a result of decreased lung compliance. | 9 months |
| Quality of Life (WHO-QOL BREF HK) | The World Health Organization Quality of Life Brief Assessment [WHOQOL-BREF (HK)] (Leung, K F; Tay, M., Cheng, S. S. W., Lin, 1997) was validated in Hong Kong and widely use in academia and clinicians since 1997. This is a 5-point Likert scale with a total of 28 Questions to identify the perceived QOL of the participants. There are four domains namely Physical Health, Psychological, Social and Environment domains with a maximum of 100. | 9 months |
