Background and study aims
This study is looking at a new way of caring for people with a lung condition called COPD (Chronic Obstructive Pulmonary Disease). Instead of staying in hospital, some patients may be able to receive hospital-level care in their own homes through a service called a “virtual ward”. This is made possible by new digital technologies that allow doctors and nurses to monitor patients remotely and stay in touch with them. The aim is to see whether this approach can help free up hospital beds and improve patient experience, while still providing safe and effective care. The study will also look at how well the virtual ward programme works when it is introduced across the Birmingham and Solihull area.

Who can participate?
Patients with COPD who are referred through different parts of the healthcare system—such as their GP, hospital teams, or community health services—may be eligible to take part. Participation will depend on when their GP practice becomes part of the study.

What does the study involve?
If a patient is eligible, they may be offered care through the virtual ward programme. This means they will receive support and monitoring at home instead of staying in hospital. Clinical staff will stay in contact with them remotely using digital tools. The study will use information from routine healthcare records to understand how the programme affects patient care and outcomes. Patients do not need to do anything extra to take part.

What are the possible benefits and risks of participating?
Being cared for at home may be more comfortable and convenient for patients, and could help reduce time spent in hospital. The study will help researchers understand whether this approach is safe and effective. As with any healthcare service, there may be risks, such as needing to return to hospital if a patient’s condition worsens. All care will continue to be provided by trained clinical staff.

Where is the study run from?
University of Birmingham (UK)

When is the study starting and how long is it expected to run for?
October 2025 to March 2027.

Study information

Primary study designInterventional
Study designA pragmatic, stepped-wedge cluster randomized trial of a care pathway incorporating virtual ward care versus standard of care for COPD patients experiencing acute exacerbations. The clusters will be GP practices, which will be randomly allocated using a constrained randomization procedure.
Secondary study designStepped-wedge cluster randomized trial

Study acronymBRIDGE
Study objectivesThe objective of this project is to evaluate the effectiveness and implementation of the new service incorporating virtual wards (the intervention) versus the usual care system with no virtual ward care (the control) for patients with COPD experiencing an acute exacerbation.
The primary trial aims are:
1. [Implementation] To estimate the average difference in total inpatient bed days per 1,000 patient-months for patients with COPD in the intervention versus usual care.
2. [Effectiveness] To estimate the average difference in risk of readmission (to hospital or virtual ward) within 30 days in the intervention versus usual care pathways.
The primary implementation outcome captures changes to both volumes of referrals and the lengths of stay of those referrals and is critical for informative economic evaluation at the system level. The primary effectiveness aim considers the health outcomes of patients. If the intervention functions as desired then the intervention should be non-inferior to usual care for both of these outcomes. Any benefits of the intervention should then be evident in terms of cost-effectiveness, patient and clinician experience, and equity outcomes. The secondary trial aims are therefore:
3. To estimate the average difference, among those with an acute COPD exacerbation referred from clinics with access to a virtual ward system compared to standard of care, in:
a. [Effectiveness] Risk of mortality within 30 days;
b. [Effectiveness/Implementation] Outpatient primary care consultation rate;
c. [Implementation] The prescribing volume during an inpatient stay;
4. To estimate differences in effectiveness and implementation between key patient groups, particularly by socioeconomic status and ethnicity.

Health condition(s) or problem(s) studiedChronic obstructive pulmonary disease (COPD)
InterventionNew service incorporating virtual wards (the intervention) versus the usual care system with no virtual ward care (the control) for patients with COPD experiencing an acute exacerbation.

This is virtual ward system that is going to be rolled out to COPD patients in the Birmingham area regardless of whether this study goes ahead. All GP practices in the study area (n=178) will serve as the clusters, which will be randomised to one of eleven trial sequences that will serve as the basis to expand eligibility to the intervention to patients in a random, staggered order between December 2025 and April 2027.
The random roll out order will be generated using covariate constrained randomisation scheme run by an independent statistician and then implemented by the service provider who will determine eligibility at the point of patient referral.
Intervention typeOther
Primary outcome measure(s)

1. Total inpatient bed days per 1,000 patient-months for patients with COPD is measured using routine care data collected retrospectively at baseline and throughout the study period
2. Readmission to inpatient care either in hospital or virtual ward within 30 days is measured using routine care data collected retrospectively at baseline and within 30 days post-discharge

Key secondary outcome measure(s)

1. Risk of mortality within 30 days of a hospital admission is measured using routine care data collected retrospectively at baseline and within 30 days post-admission
2. Outpatient primary care consultations per 100 patient-months for patients with COPD is measured using routine care data collected retrospectively at baseline and throughout the study period
3. Number of antibiotic prescriptions per patient per week admitted to hospital or virtual ward is measured using routine care data collected retrospectively at baseline and throughout the study period

Key inclusion criteriaAll patients on the COPD register for each GP in the catchment area for the data analysis will be included in the study. The intervention is being rolled out in all GPs in BCHC so there are no other inclusion criteria.
Key exclusion criteriaThere are no exclusion criteria for either clusters or individuals. However, we provide a mechanism for patients to withdraw access to their data on request.
