3. The current evidence base for virtual wards supported by virtual ward platform technologies is limited in both quantity and quality. Although the models described in the literature broadly align with the NHSScotland definition of a virtual ward, no two studies evaluated the same service delivery model. There was considerable variation across studies in virtual ward service design, components, and the type and intensity of monitoring provided. This heterogeneity makes it difficult to attribute outcomes to specific elements of the service model, particularly the contribution of the virtual ward platform technologies themselves. Interpretation of the evidence is further complicated by inconsistent terminology, most notably the interchangeable use of the terms ‘virtual ward’ and ‘hospital at home’.
4. Most of the studies focused on outcomes such as hospital admissions, readmissions, length of stay and mortality. Clear or consistent patient selection criteria are lacking. The studies primarily involved patients with respiratory or other acute conditions, limiting generalisability. While the limited evidence suggests that outcomes for patients managed in virtual wards appear comparable to those for patients managed in hospital wards, the specific added value of virtual ward platform technologies remains unclear. This reflects the fact that studies generally assessed whole models of service delivery, making it difficult to isolate the effects of the platforms from other components of care.
5. A comprehensive systematic review of 69 studies (describing 63 interventions) found low certainty evidence indicating no difference in hospital readmission rates between patients receiving technology-enabled care at home and those receiving inpatient hospital care.1 Similarly, limited mortality data suggested no difference in survival. The review stated that it remains unclear whether virtual ward platforms offer additional benefits compared with telephone or video conferencing within home-based care models.
6. The National Institute for Health and Care Excellence (NICE) guidance published in 2023 on virtual ward platform technologies for people with acute respiratory infections was based on 19 studies encompassing 6,129 people. Sixteen studies were case series and 17 were on people with COVID-19.2
NICE concluded that there was no significant difference in outcomes (including length of stay, admissions, readmissions and escalation of care) between patients monitored on virtual wards compared with hospital wards. Mortality rates were low and there was no indication of safety concerns. NICE noted that the evidence base was limited by a lack of robust, comparative data from the United Kingdom (UK), and generalisability of the findings was constrained because of study heterogeneity and a predominant focus on people with COVID-19.
7. We identified six additional primary studies published since the NICE guidance and the systematic review (ranging in size from 46 participants to over 3,000).3-8 Five were observational studies and one was a mixed‑methods evaluation. The studies varied in size and quality and only two included a comparison group. Two studies included a clinically mixed patient population. The participants in the remaining studies were people with acute heart failure, atrial fibrillation, post‑surgical patients or people with COVID‑19. Reported outcomes included hospital readmissions, mortality, length of stay and escalation of care. Although the methodological limitations of these studies mean that firm conclusions cannot be drawn, their findings are broadly consistent with the secondary evidence, suggesting that outcomes for people monitored on virtual wards may be comparable to those for people monitored in hospital wards.
8. NHS Borders piloted a virtual ward for patients with respiratory disease from January to March 2024. The ward supported 50 people over a 10‑week period. Patients were monitored remotely using wearable devices and a clinical dashboard, with daily virtual reviews. Despite some implementation challenges (for example, a reliance of locum staff and limited operating hours), feedback from patients and staff was positive. An estimated 236 hospital bed days were avoided and 84% of patients reported feeling safe and well supported at home.
