Description of intervention(s) / exposure
Pulmonary rehabilitation is a standard of care for patients with chronic obstructive pulmonary disease and other chronic lung diseases. The program duration totals 8 weeks, with 2 classes per week. Each class duration is 1 hour, overseen by a physiotherapist and respiratory physician who are fluent in Cantonese and Mandarin written and spoken language. Pulmonary rehabilitation involves exercises and education to improve lung function, symptoms and functional status. In details, the class program includes:
1st session: 15mins information, then 30 minutes of pulmonary rehabilitation exercises, followed with 15mins education on lifestyle changes to improve lung function
2nd visit onwards, measurement of blood pressure and oxygen levels before exercise. Followed by 45mins exercise, and then 15mins education. Modifications if needed on a case-to-case basis.
The class is performed as face-face at a rehabilitation gym, with group of no more than eight.
No physical informational/educational materials will be provided to participants, but participants will be provided information and weblink to Lung Foundation Australia (https://lungfoundation.com.au).
The exercises that are prescribed are: treadmill, bike, sit to stand + walk, step-ups, upper body dumbells/therabands, upper body cable machine. If the participant is unable to perform the exercise, it will be modified to suit their condition or limitations.
Participant attendance is taken every session. If there are any problems reported by participants, they will be referred back up to specialists for review.

Efficacy
Statistical methods / analysis
The intended sample size is 96 patients. This is above the current average literature figures. A Cochrane study of
the effects of pulmonary rehabilitation in patients with COPD examined 38 studies which reported 6 minute-walk test with a total of 1879 patients, approx. 49 patients per study, with a detected mean difference of 43m. We aim to detect a difference of 30m and the required sample size is 36 patients. This was derived from G*Power software (version 3.1.9.2) using paired t tests to detect the difference in means between 2 dependent means (matched pairs) with an alpha of 0.05, power 0.8, and standard deviation of results from previous retrospective data.

Summary
Brief summary
Pulmonary rehabilitation is a standard of care for patients with chronic obstructive pulmonary disease and other chronic lung diseases, including lung cancer. Language and cultural barriers prevent sufficient uptake of this treatment in particular subgroups. One large population in our region is the Chinese community. This study aims to demonstrate that a tailored Chinese language-specific pulmonary rehabilitation program will provide benefits to a significant population in our local region, and that this may influence funding and policy-making for respiratory interventions.

Who is it for?
You may be eligible for this study if you are aged 50 years and over, have a pulmonary disorder that may benefit from pulmonary rehabilitation, and have a level of English that is not proficient enough to partake in English-based classes.

Study details
All participants will take part in weekly 60 minutes classes for 8 weeks, overseen by a physiotherapist and respiratory physician who are fluent in Cantonese and Mandarin. Each class will involve exercises and education to improve lung function, symptoms, and functional status. Before starting the classes and after completion of the 8-week program, participants will have their lung function and physical function tested, as well as completing a questionnaire regarding quality of life relating to their respiratory disease.

It is hoped that this research may show that a Chinese language-specific pulmonary rehabilitation class can improve lung function and quality of life for individuals with lung disease from the Chinese community.
