Abstract
Introduction
Increasing prevalence of people living with frailty is a key challenge to healthcare providers. One solution may be virtual wards (VWs). Our research sought to: examine different frailty VW models; and determine how, why and under what circumstances VWs may work effectively. During our early research, NHS England (NHSE) started roll-out of short-term VWs intended to treat acute patients with frailty crises at home instead of hospital. We expected our work to inform NHSE policy, especially how to ‘do’ VWs better.
Methods
We conducted a rapid realist review of frailty VWs, searching published and grey literature for evidence on multidisciplinary VWs based in the UK, using a literature-based definition of VWs. Information on how and why VWs might ‘work’ was extracted and synthesised iteratively into context-mechanism-outcome configurations (CMOCs). Throughout we engaged closely with clinicians and patient/public contributors. The iterative nature of the realist review led to emerging understanding.
Results
From 28 documents, we identified two VW models: longer-term, proactive care wards admitting patients at high risk of a frailty crisis; and short-term reactive care wards for people experiencing a frailty crisis. Using evidence from both models, we generated 12 CMOCs, under three themes. First, building blocks for effective VW operation (e.g. common standards agreements, information sharing, a multidisciplinary team planning patient care remotely). Second, how the VW delivers the frailty pathway (e.g. patient selection, assessment, proactive care). Third, Patient/Caregiver empowerment. Mechanisms included motivating professionals (e.g. a ‘team-of-teams’); buy-in; building relationships: professionals, patients and caregivers. VWs should be set within frailty management guidance, and a whole-system approach to care is needed. For sustainability of VWs, proactive care for people at high risk of a frailty crisis should be provided.
Conclusions
This review has implications for optimal implementation and sustainability of frailty VWs, through proactive care and a whole system approach.
