Study exposes the risks of virtual consultations with doctors

‘Telemedicine’ is less diagnostically accurate than in-person consultations and could increase health inequalities and barriers to accessing appropriate care, a study of rheumatology patients and clinicians has found.

The study, led by the University of Cambridge in collaboration with experts at the Universities of Birmingham and East Anglia, found that there are inherent risks and benefits of telemedicine, particularly for patients with complex, serious or unpredictable conditions.

In the study, researchers examined the pitfalls and benefits of telemedicine for patients with chronic diseases.

Between April and July 2021, 1,340 patients and 111 clinicians completed online surveys. The team also conducted in-depth interviews with 31 patients and 29 clinicians. The majority of patients were from the UK (96 per cent) and had inflammatory arthritis (32 per cent) or lupus (32 per cent).

A key finding was that the vast majority of respondents, 86 per cent of patients and 93 per cent of clinicians, felt that telemedicine was worse than face-to-face consultations for accuracy of assessment, with some reporting misdiagnoses.

The team found several other major disadvantages and risks associated with telemedicine, with 90 per cent of clinicians and 69 per cent of patients saying telemedicine made it more difficult for patients and clinicians to build a trusting medical relationship, although if both parties had previously established a trusting relationship, this made it easier to continue trusting each other.

Clinicians highlighted the importance of a quick response to ‘flaring’ patients with a rapidly worsening condition, but only about half of patients were confident that they would receive a quick response to an urgent request for medical advice within 24-48 hours from their GP or hospital team.

Many patients were grateful for prompt responses despite the challenges facing clinicians, but others reported still struggling to get through administrative systems to receive any kind of response or appointment.

There was concern that telemedicine increased the potential for inequalities in treatment. Certain groups of patients were perceived to be at a substantial disadvantage.

These included those with undiagnosed or more complex conditions, for whom English was not a first language or who had hearing, cognitive or speech difficulties, and patients experiencing socio-economic disadvantage or mental health difficulties.

More than 60 per cent of clinicians and patients found telemedicine more convenient than face-to face consultations, pointing to benefits that included Covid-19 safety, no travelling and reduced waiting times as benefits.

This was particularly relevant for those in employment and for those who wanted quick check-ins, prescriptions or administrative queries along with those who struggled to get to appointments.

However, some respondents, particularly clinicians, raised concerns that telemedicine may be over-used by the NHS and hospital management as a cost and time-saving measure, rather being than in patients’ best interests.

Clinicians, only three per cent of whom felt telemedicine overall was better than face-to-face, and patients had rarely been consulted as to their preferences. Clinicians felt the NHS and managers wanted a higher proportion of appointments to be telemedicine than their own preferences.

Melanie Sloan, lead author from the Primary Care Unit at the University of Cambridge, said: “The pandemic has had a major impact on the ability of healthcare professionals to see their patients face-to-face, and this has led to a significant increase in the number of telemedicine consultations.

“While these are undeniably safer in terms of Covid-19 risk, there had been little research previously on the impact on patient care, particularly for more complex conditions.

“Our research exposes the inherent risks and benefits of telemedicine for patients with complex conditions, which may have important implications for patients who have other serious or unpredictable long-term conditions.

“As the NHS develops a telemedicine strategy, we hope there will be a thorough assessment of the clinical and psychological risks and steps taken to mitigate those risks, as well as action to address the possibility of worsening existing health inequalities for those less likely to be able to benefit from remote consultations.”

The research team concluded that telemedicine’s acceptability and safety can be improved by training for clinicians, offering patients more choice, careful selection of which patients to offer telemedicine to, and further consultation with clinicians and patients on its use.
