A 2-Year Retrospective Clinical Evaluation of a Novel Virtual Ward Model.

Objective: The Wrightington, Wigan, and Leigh NHS Teaching Hospitals Foundation Trust (WWL) developed a novel virtual ward (VW) service that integrated with community and primary care, supported healthcare throughout a patient's journey, and had a clinical workflow that could step-up or step-down care as needed. We described their VW and evaluated clinical outcomes, adherence, safety, and patient satisfaction.

Methods: Retrospective, single-center study of patients admitted to the WWL VW service from January 14, 2022 to January 31, 2024. Clinical data collected by WWL in their database for patients admitted to the VW, were matched to data captured automatically by the Current Health (CH) platform linked to the CH remote monitoring kits assigned to patients on the VW. The CH kits enabled the VW care at WWL and included a wearable device for continuous vital signs monitoring, a blood pressure cuff, and tablet. Evaluation metrics included clinical scope, clinical outcomes, adherence, safety, and patient satisfaction.

Results: There were 1835 admissions and a 93% match rate between the clinical and CH databases. About 38% of referrals were step-up (31% ambulatory care and 7% primary care) and 62% of referrals were step-down (100% inpatients). Most specialty referrals were from thoracic and acute medicine (77%). The median length of stay on the VW was 8 days [IQR 5-13], 209 (12%) admissions were escalated to the hospital, 179 (11%) escalated to the emergency department out of hours, and 29 (2%) signposted to urgent medical services. Adherence to the wearable device was 92%. There were 38 minor safety incidents (typically hypersensitivity reactions or administrative errors) and 17 expected deaths. About 94% of admissions rated the VW experience as "excellent" or "good." Results were similar between step-up and step-down referrals.

Conclusion: We have shown the VW service yielded acceptable clinical outcomes, was safe with no serious adverse events or negative impact on mortality rate. Patient adherence to the technology and satisfaction with the VW service were high. The VW service was innovative in its acceptance of a broad range of patients, expanding services beyond respiratory medicine, and in developing a step-up pathway, preventing some patients from ever taking up an acute bed in the hospital.
