Brief summary
This observational study aim to characterise patients admitted to hospital with an acute respiratory condition, or acute worsening of their chronic lung condition. This will enable identification of predictors of future risk, as well as develop potential interventions targets.
Detailed description
This will be an observational cohort study, recruiting patients who have been admitted to hospital with an acute respiratory condition. This can include exacerbation of an existing chronic lung disease such as asthma, COPD, interstitial lung disease, bronchiectasis and pleural disease, or contracting an acute illness including pulmonary embolism, pneumonia, or any other respiratory infection. The patients will be screened and recruited whilst still hospitalised and followed up for one year after discharge. The participants will undergo a baseline study visit while in hospital, with the option to have further follow up visits (up to three occasions) in the following year to assess clinical recovery. The participants will be offered the choice to undertake the follow up assessments via any of the following routes: * a telephone consultation or * a face to face visit either in the Biomedical Research Centre (BRC) or * during a research visit from another ethically approved study or * during routine clinical follow up organised by the hospital clinical team. The participants can choose not to attend any further follow up visits after discharge. Any planned clinical follow-up arranged by the hospital team will occur according to clinical needs. If the participant is re-admitted during the 12 months after enrolment, assessments identical to the baseline visit can be repeated. A final remote visit will be carried out at 12 months post-discharge (+/- 1 month) to collect data about health care utilisation (e.g. hospitalisation rate, length of stay in hospital, death rate, antibiotic/steroid prescriptions) from both primary and secondary healthcare records. The participants are not required to attend this final visit as data will be collected remotely.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 30 days mortality rate | 30 days | To calculate the percentage of mortality within 30 days from consent |
| Length of index hospital admission stay | Variable (up to 52 weeks) | To calculate the length of the index hospital stay |
| 30 days hospital re-admission rate | 30 days | To calculate the percentage of readmission due to the same acute respiratory illness within 30 days from consent |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time from consent to death (respiratory causes and all causes) | 52 weeks | To measure the time from consent to death within 52 weeks from consent. This will include both respiratory and all causes of mortality |
| Total number of hospital readmission due to same underlying chronic lung disease. | 52 weeks | To evaluate the number of hospital readmission episodes due to same underlying chronic lung disease over a 52 weeks period. |
| Total number of non-hospitalised exacerbations of underlying chronic lung disease | 52 weeks | To evaluate the number of non-hospitalised exacerbations of chronic lung disease e.g. asthma, Chronic Obstructive Pulmonary Diseases (COPD), etc. over 52 weeks |
Other
| Measure | Time frame | Description |
|---|---|---|
| Assessment of breathlessness using eMRC dyspnoea scale | 52 weeks | To evaluate the degree of breathlessness at baseline and following recovery from acute respiratory illness using Extended MRC dyspnoea scale(eMRC). eMRC dyspnoea scale ranges from 1 to 5b with higher score indicates worse outcomes. |
| Assessment of quality of Life/symptoms using St. George's Respiratory Questionnaire (SGRQ) | 52 weeks | St. George's Respiratory Questionnaire (SGRQ) is a disease-specific instrument designed to measure impact on overall health, daily life, and perceived well-being in patients with obstructive airways disease. Scores range from 0 to 100, with higher scores indicating more limitations. |
