Description of intervention(s) / exposure
Following provision of informed consent from the participants, participants will be required to complete a series of outcome measures which include a lung function test via a portable spirometry and a inspiratory muscle strength test via a Sniff Nasal Inspiratory Pressure (SNIP) machine. These outcome measures will be repeated once again at time of discharge from hospital post elective cardiac surgery to ascertain changes to the inspiratory muscle strength following cardiac surgery
Initial testing will occur at cardiothoracic preadmission clinic. Patients attend cardiothoracic preadmission clinic when their scheduled cardiac surgery is between 2 weeks to 1 month.
Duration of testing is approximately 5 minutes, time may vary depending on patients understanding the instructions

Postoperative pulmonary complications (PPCs), e.g. chest x-ray radiological report of atelectasis/consolidation, an unexplained white cell count exceeding 11.2 cells/mm3 or administration of respiratory antibiotics postoperatively, fever (oral temperature > 38 degrees) with no obvious non-pulmonary focus, positive signs of infection on sputum microbiology, production of purulent (yellow/green) sputum that was different from preoperative status, percutaneous oxygen saturation < 90% on room air diagnosis of pneumonia/chest infection by attending physician, readmission to the intensive care (ICU) or high-dependency unit (HDU) or a prolonged stay (>36 hours) in ICU or HDU due to respiratory problems.
A member of the research team will be screening through the participant’s medical history to ascertain the occurrence of PPCs. PPC is said to have occurred based on the presence of four or more of the examples provided.

Eligibility
Key inclusion criteria
To be eligible, participants are required to:
- Be over the age of 65 years
- Possess a score of six or less on the Rockwood Clinical Frailty Score (RCFS).
- Undergoing elective cardiac surgery via sternotomy.
Patients from non-English speaking backgrounds who require language assistance will be included to ensure the sample represents the population at SWSLHD. An interpreter or a family member nominated by the participant will assist in interpretations during the recruitment and throughout the study.

Statistical methods / analysis
An intention to treat analysis will be conducted for the purpose of this study. Changes in inspiratory muscle pressure between baseline and post-operative will be analysed descriptively. The rate of PPCs between the non-frail and frail groups will be analysed using the independent T-test. Repeated ANOVA will be used to analyse between group differences in MIP and spirometry results. All data analysis will be conducted using SPSS v26 (IBM) available through UNSW.

Summary
Brief summary
Older people are more likely to develop postoperative pulmonary complications (PPCs) after cardiac surgery due to the possible age-related decline in inspiratory muscle strength. We aim to investigate the impact of frailty on inspiratory. muscle strength amongst older people following elective cardiac surgeries. We also aim to investigate the impact of frailty on lung function and PPCs. The findings of the study may elucidate potential means to identify individuals who may be more at risk of PPCs following surgery and could assist in the development of tailored post-surgical management strategies.
