Technology-enabled virtual wards the future of healthcare

With an elective care backlog in excess of 7 million [1], record high workforce shortages [2] and decaying estates, our healthcare system is close to breaking point. Numerous tools have been deployed to try and combat these problems, but they continue to fall short of the mark. Not all hope is lost though. Driven by the global Covid-19 pandemic, we have seen a flurry of new techniques and solutions enter the market, promising to solve our problems and redefine healthcare nationally. One of these tools, Virtual Wards, has established such a strong base of supporting evidence that they can no longer be ignored. But are they the answer to our prayers? When deployed in a technology-enabled manner, following a structured implementation plan, they just might be.

In response to rising demand and in preparation for winter, NHS England (NHSE), Health Education England (HEE) and NHS Digital (NHSD) are collaborating to support ICSs in adopting Virtual Wards. Outlined in a two-year funded transformation program, the ambition is to have 40-50 Virtual Ward beds available in each Trust across the UK (24,000 beds in total). This is to be delivered in a tight time frame, with all Trusts required to meet the capacity target by December 2023.

With NHSE putting their faith in Virtual Wards, so too should we. But what is a Virtual Ward? What kind of benefits can they deliver and how can we ensure that our Virtual Ward is actually successful?

About Virtual Wards

Virtual Wards aren’t new, with the first examples deployed over 15 years ago [3]. At their core, they aim to move patients out of hospitals and into homes, whilst still delivering an acute level of care. Despite being used across the UK (and globally), their model of care remains largely unchanged, with little innovation or improvement seen in the space. That is, until now.

Many Virtual Wards currently in use are ‘traditional’ in their approach, with the care delivery model underpinned by telehealth services and routine home visits. This approach requires significant clinical time investment, proliferating systemic workforce problems and, in some cases, functioning to hinder the service rather than help it.

There is, however, a ‘non-traditional’ Virtual Ward model, one that uses state of the art remote monitoring technology to deliver acute level care to patients [cite]. These models are defined as ‘Technology-enabled Virtual Wards’, delivering quality care without the same workforce demand as traditional models.

Technology-enabled Virtual Wards

The NHS defines a technology-enabled Virtual Ward (TEVW) as ‘the management of patients via a digital platform’. A broad definition which could be used to describe any number of solutions currently on the market. It is also, a misleading one, as beyond the shared use of technology, there is very few similarities between the different solutions. App only, monitoring + app and telehealth platforms can all be considered as technology enabled Virtual Wards, but each has a unique set of benefits and delivers care in a novel way.

Although telehealth and app only solutions have their place, providers should be focused on deploying Virtual Wards that utilise hospital grade remote monitoring technology. These Virtual Wards are the new frontier of digital health, delivering a broader suite of benefits, to a greater patient cohort, than any other solution [4].

For the remainder of the article, when we refer to a TEVW, we refer specifically to one that is using hospital grade, remote monitoring technology.

Benefits of Technology-Enabled Virtual Wards

Not all TEVWs are built the same, with maximum (in terms of both breadth and depth) benefits only observed in those that integrate remote monitoring in patient care pathways. But what are these benefits? Where, how and by who will they be felt? To understand the potential impact of TEVW, we have conducted benefits modelling using leading technology within the Virtual ward space, Masimo SafetyNet as an example, to explore the following areas:

  • Average Length of Stay
  • Workforce efficiency
  • Readmission rate & admission avoidance
  • Backlog reduction
  • Release of acute bed capacity

Our analysis models the potential positive impacts that an average sized Trust (778 beds) could achieve by adopting a TEVW. This is not the only potential application though. With appropriate tailoring, TEVWs can be applied to any use case, with the technology being used globally to support the care of patients suffering from any number of conditions from cancer to heart failure.

In the context of the acute emergency and orthopaedics cases, we understand there to be two main applications for a TEVW respectively: avoiding admission and expediting discharge. The benefits of TEVWs will be discussed in the context of these primary applications.

1) Avoiding admission

TEVWs offer providers a way to avoid unnecessary admissions and re-admissions to the acute setting, instead delivering care to patients in the home environment. Acute patients, such as emergency department attendees, can be admitted to the Virtual Ward, rather than the physical ward, preventing the occupation of an acute bed.

Our benefits modelling indicates that for an average sized Trust of c.760 beds, up to 7,000 bed days could be released through readmission avoidance of acute emergency patients [5,6,7,8]. This would save an estimated £3 million in avoidable readmission costs [7,9] and release 63 hours of clinical resource back to patient facing activities [10]. In addition to financial and capacity benefits, research has shown that patients have a greater perceived quality of care and sense of empowerment when treated through a TEVW model [11].

In the context of acute emergency cases:

2) Early discharge

TEVWs enable postprocedural remote monitoring and encourage early discharge, releasing both clinical and bed capacity [12,13].

Wearable sensors alert clinicians to changes in a patient’s condition, in real-time, helping the remote management team to intervene sooner and ensuring patients receive the same quality of care within the Virtual Ward [12,13]. This functionality brings the home environment in line with the acute environment and provides clinicians with the confidence they need in order to discharge more acutely unwell individuals, earlier. 1/3 patients stay in hospital beyond the necessary point of care, the ability of TEVWs to reduce length of stay will be critical in reducing this number and expediting discharge. You can read more about this in our D2A technology article here.

Reducing length of stay will release clinical and bed capacity, allowing critically ill patients to be treated with fewer delays and removing a key bottleneck in care delivery. In the case of primary hip and knee procedures, the ambition is that technology enabled Virtual Wards will reduce length of stay by up to 3 days. This could release an estimated 900 bed days which could be utilised to addressing the current backlog for orthopaedic procedures.

In the context of orthopaedics patients:

Reduce length of stay

Implementing technology-enabled Virtual Wards 

The potential benefit of technology enabled Virtual Wards is clear and as a result NHSE calling for their rapid adoption [14,15]. However, without firm guidance on how to implement these solutions effectively, they may fail to deliver expected benefits and jeopardise patient care [16].

Learnings from previous Virtual Ward implementations have been distilled into a set of critical success factors which must be considered if the TEVW is to be delivered effectively. Sourcing the right solution, defining a clear objective, mapping the commercials and understanding the use case are all pivotal in achieving success. Steps to address these factors are outlined as part of our comprehensive Virtual Ward implementation guide.

Akeso’s methodology is based on Masimo SafetyNet which you can find here.

Sourcing the right solution, and partnering with the right provider, are essential in ensuring the Virtual ward is both clinically compliant and highly effective. Several providers claim to meet these criteria, but with only a few functioning examples of TEVWs locally, it is difficult to assess the validity of these statements. route of sourcing an effective, complaint TEVW is utilise the Sparks Dynamic Purchasing System (DPS) framework. Spark DPS categorises leading technology providers across a variety of sectors based on their capabilities and offerings. We have summarised these providers, and what they offer (based on the DPS framework), below.

Figure 1 – Summary of key technology-enabled Virtual Ward providers
Figure 1 – Summary of key technology-enabled Virtual Ward providers on the Spark DPS framework.

When considering which TEVW supplier to use, it is important to consider future TEVW applications, beyond the current target. Many providers have Virtual Wards up and running, supplied by different organisations. This can lead to problems with integration, consistency and quality for both patients and clinicians. The aim should be to procure a single solution that is scalable and adaptable to all areas of your service. Masimo SafetyNet is a robust example of a TEVW solution that holds this capability.

The Future

We currently have a discharge problem in the NHS, with patients waiting up to 9 months to be sent home [cite]. Virtual Wards will support expedited discharge, reducing Length of Stay back toward national targets. Read more about it in our Discharge to Assess (D2A) technology enablement article ‘Turning homes into hospitals’.

Although current benefits are obvious, we should begin to think about what role TEVWs might play in the future of healthcare. Using the clinical information TEVWs provide, we could look to begin moving the discharge threshold, allowing higher acuity patients to be treated in an at home environment. Doing so would extend the benefits of Virtual Wards, beyond what current models (including our own) predict.

The vision for technology
Figure 2 – The vision for technology enabled Virtual Wards

But the future of Virtual Wards doesn’t just lie in moving the discharge threshold. Traditionally, Virtual Wards were deployed to prevent patient admission- the opposite end of the care pathway to the current discharge focus. We believe technology-enabled Virtual Wards could eventually be deployed across every stage of the patient care journey, not just the bookends, supporting a movement toward personalised medicine and redefining care pathways completely. There is evidence of this globally already, with Virtual Wards across Australasia supporting entire cancer care pathways [17].

Future applications of technology-enabled Virtual Wards
Figure 3 – Potential future applications of technology-enabled Virtual Wards, across the entire patient care pathway.

It is important to keep these opportunities top of mind as we deal with our current issues, continuing to innovate and adapt during a time of immense pressure. Doing so will ensure that solutions implemented can flex and change as our needs do, remaining relevant long into the future.

Transforming homes into hospitals

D2A pathways and associated practices are key tools in expediting patient discharge, relieving pressure on the acute environment and improving patient flow [1,2]. Although effective on their own, by applying technology in new and innovative ways, these pathways can be further enhanced to generate further benefits.  

Supporting technology is best viewed as ‘catalysts’ for D2A pathways. When implemented effectively, they can amplify the benefits of discharge to assess such as: improved patient experience, faster discharge, and the release of capacity for other clinical need.

The role of technology enablement in D2A

The number of D2A enabling technologies is increasing continually, catalysed by the global Covid-19 pandemic. Solutions such as “Virtual Wards” and various health apps provide cost-effective ways of delivering care to more patients in a resource efficient manner [3,4].  With so many technologies, solutions, and providers now on the market, the space has become confusing. An understanding of what the technologies do, what benefits they may generate, and how they support more efficient discharge is not easily come by.

In order to help, we have clustered the current propositions into three main types: ‘alternative models of care’, ‘care management tools’ and ‘service augmenters’ which are explained below. Each of these enhances one or more of the D2A pathways as defined in our previous articles.

Extended models of care to include a patients’ home

Technology solutions labelled as ‘alternative models of care’ seek to fundamentally redefine the patient care pathway. Key solutions in this space include Virtual Wards and Telehealth Services, effectively turning our homes into hospitals.

Technology-enabled Virtual Wards are pioneering, demonstrating the ability to move patients out of the acute environment whilst maintaining the same quality of care [5]. In Masimo’s SafetyNet solution, for example, this is enabled by remote monitoring, allowing real-time assessment of patient “vital signs” and automated alerts when patients conditions begin to deteriorate [6]. When implemented effectively, these solutions can reduce length of stay and release clinical capacity.

Homes into hospitals

Care management and enhanced communication between professionals

The second suite of D2A enabling technologies aim to consolidate the care management process, presenting a complete view of the end-to-end process. Patient discharge is managed by multidisciplinary teams, each uniquely involved in the movement of the patient out of the acute environment and their continued care in the community. Historically, communication between these groups has been limited, delaying discharge, and causing continuity issues in care delivery.

Innovative technology platforms such as ‘Hospital to Home’ [7] provide consolidated views of both the discharge process and the overall patient care pathway, in a way that fosters collaboration between clinical stakeholders. In the context of D2A, these platforms can enable faster, more consistent discharge practices, supporting clinicians to understand discharge stages, who needs to be involved and what needs to happen when.

Accessing national capacity as and when it is needed

Driven by the growing workforce shortage across the NHSE, several 3rd party clinical service providers have been established over the past few years. These providers offer access to clinicians, via telehealth platforms, to support with rate-limiting tasks such as triage. diagnostic and outpatient assessments. In doing so they expand a provider’s workforce, reducing bottlenecks and delays.

These services can diffuse pressure, such as during Winter, to mitigate against seasonal variation for the period when it’s needed. Virtual Lucy [8] and Medefer [9] are industry leading providers of these services, not only demonstrating the ability to reduce discharge delays but also preventing patients from unnecessary admission to acute services in the first place.

Ensuring the solution is successful

The implementation and management of digital transformations is rarely done well, but there are steps that can be taken to improve the chance of success. Each technology implementation is different, with unique challenges and success metrics. There are, however, key success factors, common to all implementations regardless of technology type or use. The programme objective, intended use case and commercial viability are all essential to consider if the technology implementation is to achieve success.

Programme objective

A single objective should be defined to drive progress and foster alignment across the delivery team. 

Often, we see large programmes of work undertaken as a knee jerk reaction to changing pressures across our health landscape, resulting in ‘solutions’ that are naïve of the problem they attempt to solve [10].

Providers must be proactive in defining their programme objective, setting a clear goal before work commences. It should be easily understood and clearly linked to actions that support its realisation. Having a single, clearly defined objective (for example, enhanced patient experience) will align stakeholders, keep the project on course and ensure positive outcomes are achieved.

The clarity of this objective will then lead to Key Performance Indicators (KPIs – such as a relevant PROM, percentage of patients in an acute site beyond their point of need, and patients supported at home) which can be used to assess the success of the solution.

Intended use case

Technology should be aligned to where it is needed most. 

Discharge processes differ significantly, not just between providers but between clinical pathways. It is unlikely, therefore, that there will be a ‘one size fits all’ technology solution across providers; adaptation is always required to tailor the needs of each unique situation. Many providers fail to consider this, deploying generalised rather than tailored solutions. Providers should focus on strategic deployment models, delivering technology solutions to highest need or highest-pressure pathways first, and then expanding these solutions across lower priority / lower risk pathways over time.

In defining the use case for the D2A enabling technology, an understanding of the underlying population should be developed. Demographic factors such as ethnicity, gender and comorbidity are known to influence the efficacy of healthcare interventions. Understanding these factors will support delivery of tailored, technology-enabled, discharge solutions.

Commercial viability

The commercial viability of the technology should be defined early in the project lifecycle. 

The balance between costs and benefits (as captured in KPIs) underpins the commercial viability of a technology solution. Through defining a clear objective and understanding the intended use case, the benefits of a technology solution can be easily understood. The financial implications (both ongoing and upfront) of the technology should be modelled to support an equal understanding of associated costs.

Aside from Virtual Wards, which have £450 million in backing, there is no ring-fenced funding available for D2A enabling technologies. A formal business case will be required to secure funding for initial set up and continued use of these technologies. To complete the NHSE business case in full, clear definition of costs, benefits, and ROI time horizons will be required. Importantly, financial benefits must be shown to outweigh costs, with a robust evidence base established to support this conclusion.

What’s next

Having understood the D2A enabling technology landscape, and how to ensure these tools work to support you, the task of delivery comes next.  This is where all the value is generated. The final article in our series will focus on setting up delivery programmes to succeed, demystifying the process by establishing the key elements for success.

Technology-enabled Virtual Wards

How hospital grade remote monitoring technology can enable the delivery of high-impact patient outcomes.

Technology-enabled Virtual Wards have arrived, are you ready?

The NHS must establish 24,000 Virtual Ward beds by December 2023 to support a targeted increase of 30% in elective care procedures by 2025. The delivery of effective ‘in-hospital’ patient care depends on reliable communication, monitoring, and alerts. Maintaining this level of care efficiently and effectively in a Virtual Ward, outside of the hospital, requires reliable, trusted, proven and privacy-compliant solutions for timely detection, prevention, and treatment. Masimo SafetyNet® is a Digital Health platform from Masimo, whose innovative monitoring products have been in use across the NHS for over 15 years, with a proven track record of success.
