| Study characteristics | ||
| Methods | Parallel randomised trial Study conducted between February 1998 and August 1999. |
|
| Participants | Setting: UK Patients with chronic obstructive airways disease Number recruited: hospital at home: 100, hospital: 50 |
|
| Interventions | Hospital at home Type of service: admission avoidance from A&E. Care provided by outreach specialist nurses and GP and community nurses if required. |
|
| Outcomes | Respiratory function, readmission, quality of life | |
| Notes | Few details on measure of quality of life Follow up: 2 weeks and 3 months Funding: North Mersey Community (NHS) Trust and University of Liverpool (UK) Conflicts of interest: none declared Ethical approval: district ethical committee This author contributed IPD for a previous update of this review (Shepperd 2016a). |

| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Ratio of 2:1 (hospital at home: hospital) |
| Allocation concealment (selection bias) | Low risk | Opaque, sealed envelopes |
| Baseline outcome measurements (selection bias) | Low risk | Baseline outcome measurements done prior to intervention for respiratory function; no relevant differences found |
| Baseline characteristics (selection bias) | Low risk | Baseline characteristics of the study and control groups are reported and are similar |
| Blinding of participants and personnel (performance bias) All outcomes | Low risk | Blinding of participants and personnel not possible Hospital readmission was a primary outcome, with decision to admit made by hospital staff |
| Blinding of outcome assessment (detection bias) Subjective outcomes | Unclear risk | A small group of participants completed the St George's Respiratory Questionnaire |
| Blinding of outcome assessment (detection bias) Objective outcomes | Low risk | Low risk for admission to hospital, changes in FEV1 score |
| Incomplete outcome data (attrition bias) All outcomes | Low risk | Loss to follow‐up: hospital at home: 7/100; hospital: 5/50 |
| Selective reporting (reporting bias) | Low risk | All outcomes reported (received trial data set) |
