COVID-19: An introduction to digital health resources for clinicians and researchers

Moving to an online service

Researchers who are looking into how to transition their face-to-face service into an online version should look at the NHS Digital's Digital Inclusion Guide or the similar digital exclusion/widening participation literature. Beyond the technical issues, it is an acknowledged fact that these transitions may result in particular groups being excluded from services – typically patients who are not technology users, or in itinerant population groups. Alternatively, the opposite can also occur, whereby a new set of service users can access care, particularly those who are physically immobile or reluctant to engage with clinicians in person, pregnant mothers or those with childcare responsibilities. Patients who are not technologically enabled will not necessarily be excluded from services, but rather staff may have to consider ways to support them, or encourage their carers/family to support activities. For example, a carer can book in a video consultation for a patient. 

A second point to consider is that new technology necessitates new workflows in care pathways. This often means new roles for reception staff and others in the triage process. If possible, co-producing and iteratively refining these processes with colleagues is the best way to get them to work. Peer learning is also important, and it would be advisable to identify staff members with expertise in digital health who can teach/provide leadership.

The exclusion issue can have effects beyond those with low levels of digital literacy, who typically can struggle to access services. For example, research in Cornwall from the EPIC project shows that when trying to provide digital services for care homes, not all homes had good internet access. Slow speeds made video-calls impossible for some. Furthermore, care homes that did have internet connections may not have them throughout the building but typically only in communal areas.

While there is a current and pressing need for digital healthcare, it not always possible to offer services due to these sorts of pragmatic limitations. The first step in trying to transition any service to an online version is to assess what implementation issues might arise, who might be excluded as a result, and what can be done to mitigate these issues. For example, not all NHS-issued computers have webcams, meaning that if a member of staff wanted to conduct a video consultation they would have to provide their own (although the NHS is working hard to provide all with webcams). Staff should also identify the essential features required for their intervention (e.g. internet connection or webcam) and not worry about over complicating the solution. Choosing a complex process will frequently result in user dissatisfaction or disengagement; it is much easier to click on a link to start a video conference than it is to download and install software.

Solutions do not have to be overly technical in nature, and often simple implementation issues are the ones that prevent effective roll- out. Staff should have a mind-set of Quality Improvement, whereby the technology is facilitating staff to support patients, rather than being the central focus.

If you feel that you might be slower delivering an online consultation, spend more time familiarising yourself with the patient's record or issue the patient forms to complete before the call to obtain basic clinical information. In short, some of the limitations of digital services can be mitigated with small amounts of planning, and scaffolding.

Evaluation

NICE, whose evidence framework for digital technologies remains the gold standard for determining how effective a digital product is, published several papers detailing what they consider the most effective evidence base for this type of service. Campbell et al (2018) analysed five years of submissions to the medical devices technology assessment panel, looking at which types of evidence were submitted and the outcome of the device being accepted by the panel (i.e. commissioned). They found no significant relationship between RCTs and devices being accepted. Instead, it seems the panel prefers a spread of evidence, namely smaller studies in specific areas such as usability, economic analysis and implementation. In short, if looking for an evidence base for a technologically-enabled intervention, RCTs are less useful than economic, patient and practitioner usability, and implementation studies.

However, the existing literature on digital health comes with the caveat that most of it was not conducted with COVID-19 patient groups in mind. Rather, studies looked at healthier patient cohorts, in non-pandemic settings, not all of which are in the UK.

To this end, there are a number of sources for learning about evaluation for digital health services; perhaps the most comprehensive introduction is Public Health England's Evaluating Digital Health Products series of online guides. Also useful can be:

• NHS Digital's Assessment Questions which helps you understand what developers have to do to get into the NHS App Library.
• NHSx Digital Data and Technology Standards.
• For a specifically Primary care focus, you might consider the NHSE's Using Online Consultations in Primary Care Implementation Toolkit.

Researchers also might consider the guidance produced by Trisha Greenhalgh about video consultation. The paper includes a useful decision-making tool for how and when to use remote triage in primary care. Some NHS organisations have moved away from providers like Zoom for security reasons and are utilising Microsoft Teams for video conferences work instead.

Further educational material can be found on Health Education England’s COVID online training packages, with specific sections on primary and secondary care.

Data Security

Data security will be a consideration for staff whose research involves switching to online surveys. Institutions typically require researchers to use an agreed platform for data collection and processing. For example, to use an account with a private company like SurveyMonkey may require the researcher to get a copy of a data processing agreement. Trusts are likely to have similar concerns.

UK-focused Implementation Literature

There is not much literature that would give clinician or researchers specific instructions about how to transition your face-to-face service to an online version in the UK. In addition, none of the studies were conducted in a pandemic, so the findings will need to be adapted. Suggested reading includes Clouder et al. (2006), Greenhalgh et al. (2018), Greenhalgh (2018), Varsi C et al. (2019), Abimbola et al. (2019), Schimmer et al. (2019), Greenhalgh et al. (2020). There is a wider set of literature concerning the transition to online delivery of medical education. However, large sections are not relevant to the current situation. Further to this the NIHR’s Research Design Service (NW) have produced a collection of COVID-relevant research methodologies, largely aimed trials work.

Centre for Health Technology

The University of Plymouth's Centre for Health Technology digital health testbed is a project between Kernow Heath CIC (a network of 59 GP practices) and digital health researchers at the University. Kernow Health CIC offers a service to digital health providers connecting them to practices in Cornwall to review and evaluate different products, known as the Digital Health Testbed. University of Plymouth academic staff provide service evaluation, protocol and research expertise. We evaluate products against the most up-to-date NICE framework for digital health, providing real world, independently conducted evaluations of digital health products.

The Centre’s staff have been engaging with senior commissioning figures in the local trusts to provide examples of health tech companies to deliver services, as well offering potential evaluations for these new products in light of the COVID-19 situation. We continue to work with a lead-generation company in London to identify additional, established international companies in the Nordics, Israel, Spain and Italy that might have potentially useful digital products for the NHS during this time of crisis.
