Description of intervention(s) / exposure
This study will assess the impact of fractional exhaled Nitric Oxide (FeNO) in people admitted to hospital with an acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) on 12-month readmission risk for AECOPD.
The FeNO will be measured once within 24 hours of admission using the NIOX VERO device.
Additional known and hypothesised confounders of hospital readmission will be measured once within 24 hours of admission including 1) patient demographics, 2) Spirometry using the EasyOne Spirometer, 3) Severity of COPD using the COPD Assessment Test, 4) breathlessness using the Modified MRC dyspnoea scale, 5) medical co-morbidities using the Charlson Comorbidity Index, 6) anxiety using the Hospital Anxiety and Depression scale and 7) laboratory evidence of allergy and with blood eosinophil level, IgE level and RAST f or dust mite, pollen, animal and mould mix.
These measurements will be administered in conjunction with a member of the study team (respiratory specialists or respiratory registrar or respiratory clinical nurse). Blood tests will be obtained from blood samples obtained at admission by emergency medicine staff as part of routine care. Any remaining blood tests will be additionally requested.

Outcomes
Primary outcome [1] 305684 0
Hospital readmission for COPD exacerbation - assessed by discharge summary with discharge diagnosis as "exacerbation of COPD". Sources of discharge summary will be the institution's electronic medical record or general practice records.
Timepoint [1] 305684 0
12 months post-discharge
Secondary outcome [1] 346167 0
Repeat exacerbation of COPD - determined by patient, carer or general practitioner self-report
Timepoint [1] 346167 0
12 months post-discharge. This outcome will be assessed at intervals of 6 weeks, 3 months, 6 months, 9 months and 12 months post-discharge (+/- 1 week).
Secondary outcome [2] 346168 0
Time to hospital readmission for COPD exacerbation determined by time in days from discharge to readmission based on available discharge summary documentation.
Timepoint [2] 346168 0
12 months post-discharge

Statistical methods / analysis
Predictors for the primary outcome (readmission for COPD exacerbation) will be identified by using a multivariate logistic regression model incorporating FeNO level and other known and suspected factors associated with COPD readmissions. Associations between FeNO and readmission will be presented as odds ratios. Systemic steroids can affect FeNO measurements. Therefore, outcomes will also be analysed by dose of systemic corticosteroid prior to FeNO measurement.

Predictors of the secondary outcomes (time to readmission for repeat exacerbation of COPD and time to repeat exacerbation) will be identified by using a Cox Proportional Hazards regression model or logistic regression model as appropriate incorporating FeNO level and other known and suspected factors associated with COPD readmissions. Associations between FeNO and readmission will be presented as hazard ratios (Cox Proportional Hazards model) or odds ratios (logistic regression model).
