Advantages and limitations of virtual online consultations in a NHS acute trust: the VOCAL mixed-methods study

Background

There is much enthusiasm from clinicians, industry and the government to utilise digital technologies and introduce alternatives to face-to-face consultations.

Objective(s)

To define good practice and inform digital technology implementation in relation to remote consultations via Skype™ (Microsoft Corporation, Redmond, WA, USA) and similar technologies.

Design

Multilevel mixed-methods study of remote video consultations (micro level) embedded in an organisational case study (meso level), taking account of the national context and wider influences (macro level).

Setting

Three contrasting clinical settings (Diabetes, Antenatal Diabetes and Cancer Surgery) in a NHS acute trust.

Data collection and analysis

Macro level – interviews with 12 national-level stakeholders combined with document analysis. Meso level – longitudinal organisational ethnography comprising over 300 hours of observations, 24 staff interviews and analysis of 16 documents. Micro level – 30 video-recorded remote consultations; 17 matched audio-recorded face-to-face consultations. Interview and ethnographic data were analysed thematically and theorised using strong structuration theory. Consultations were transcribed verbatim and analysed using the Roter interaction analysis system (RIAS), producing descriptive statistics on different kinds of talk and interaction.

Results

Policy-makers viewed remote video consultations as a way of delivering health care efficiently in the context of rising rates of chronic illness and growing demand for services. However, the reality of establishing such services in a busy and financially stretched NHS acute trust proved to be far more complex and expensive than anticipated. Embedding new models of care took much time and many resources, and required multiple workarounds. Considerable ongoing effort was needed to adapt and align structures, processes and people within clinics and across the organisation. For practical and safety reasons, virtual consultations were not appropriate for every patient or every consultation. By the end of this study, between 2% and 20% of all consultations were being undertaken remotely in participating clinics. Technical challenges in setting up such consultations were typically minor, but potentially prohibitive. When clinical, technical and practical preconditions were met, virtual consultations appeared to be safe and were popular with both patients and staff. Compared with face-to-face consultations, virtual consultations were very slightly shorter, patients did slightly more talking and both parties sometimes needed to make explicit things that typically remained implicit in a traditional encounter. Virtual consultations appeared to work better when the clinician and the patient knew and trusted each other. Some clinicians used Skype adaptively to support ad hoc clinician-initiated and spontaneous patient-initiated encounters. Other clinicians chose not to use the new service model at all.

Conclusions

Virtual consultations appear to be safe, effective and convenient for patients who are preselected by their clinicians as ‘suitable’, but such patients represent a small fraction of clinic workloads. There are complex challenges to embedding virtual consultation services within routine practice in the NHS. Roll-out (across the organisation) and scale-up (to other organisations) are likely to require considerable support.

Limitations

The focus on a single NHS organisation raises questions about the transferability of findings, especially quantitative data on likely uptake rates.

Future research

Further studies on the micro-analysis of virtual consultations and on the spread and scale-up of virtual consulting services are planned.

Real-World Implementation of Video Outpatient Consultations at Macro, Meso, and Micro Levels: Mixed-Method Study

Background

There is much interest in virtual consultations using video technology. Randomized controlled trials have shown video consultations to be acceptable, safe, and effective in selected conditions and circumstances. However, this model has rarely been mainstreamed and sustained in real-world settings.

Objective

The study sought to (1) define good practice and inform implementation of video outpatient consultations and (2) generate transferable knowledge about challenges to scaling up and routinizing this service model.

Methods

A multilevel, mixed-method study of Skype video consultations (micro level) was embedded in an organizational case study (meso level), taking account of national context and wider influences (macro level). The study followed the introduction of video outpatient consultations in three clinical services (diabetes, diabetes antenatal, and cancer surgery) in a National Health Service trust (covering three hospitals) in London, United Kingdom. Data sources included 36 national-level stakeholders (exploratory and semistructured interviews), longitudinal organizational ethnography (300 hours of observations; 24 staff interviews), 30 videotaped remote consultations, 17 audiotaped face-to-face consultations, and national and local documents. Qualitative data, analyzed using sociotechnical change theories, addressed staff and patient experience and organizational and system drivers. Quantitative data, analyzed via descriptive statistics, included uptake of video consultations by staff and patients and microcategorization of different kinds of talk (using the Roter interaction analysis system).

Results

When clinical, technical, and practical preconditions were met, video consultations appeared safe and were popular with some patients and staff. Compared with face-to-face consultations for similar conditions, video consultations were very slightly shorter, patients did slightly more talking, and both parties sometimes needed to make explicit things that typically remained implicit in a traditional encounter. Video consultations appeared to work better when the clinician and patient already knew and trusted each other. Some clinicians used Skype adaptively to respond to patient requests for ad hoc encounters in a way that appeared to strengthen supported self-management. The reality of establishing video outpatient services in a busy and financially stretched acute hospital setting proved more complex and time-consuming than originally anticipated. By the end of this study, between 2% and 22% of consultations were being undertaken remotely by participating clinicians. In the remainder, clinicians chose not to participate, or video consultations were considered impractical, technically unachievable, or clinically inadvisable. Technical challenges were typically minor but potentially prohibitive.

Conclusions

Video outpatient consultations appear safe, effective, and convenient for patients in situations where participating clinicians judge them clinically appropriate, but such situations are a fraction of the overall clinic workload. As with other technological innovations, some clinicians will adopt readily, whereas others will need incentives and support. There are complex challenges to embedding video consultation services within routine practice in organizations that are hesitant to change, especially in times of austerity.
