Britain’s industry regulator has emphasized the need for updated regulations governing AI technologies used within the NHS and other healthcare environments. The Medicines and Healthcare Products Regulatory Agency (MHRA), responsible for overseeing medical devices and the licensing of treatments in the UK, has released a set of 44 recommendations aimed at modernizing its regulatory framework in response to the growing integration of AI in healthcare.
Lawrence Tallon, chief of the MHRA, spoke to the BBC about how AI is poised to become a routine part of NHS healthcare delivery. He stated, “What I would expect is that patients will… increasingly see AI as part of the way that normal NHS healthcare is delivered,” while stressing the importance of maintaining patient trust and confidence throughout this transition. The MHRA’s report, informed by contributions from over 12,000 patients and clinicians, advises on continuous monitoring of AI products and ensuring their removal if performance declines. Other suggestions include giving patients clear rights to be informed when AI influences their care, empowering regulators to penalize developers whose products fail standards, and introducing an AI “L plate” system to allow cautious piloting of new models under professional supervision.
Tallon highlighted that current medical device regulations were designed originally with traditional products in mind, such as hip replacements or stethoscopes. While these guidelines suffice for simple AI applications like identifying known symptoms on scans, they fall short for more sophisticated AI systems that evolve post-approval. “Unlike most of the medical products we’re used to regulating, these products continue to change after the point of authorization,” he explained, referring to how AI systems adapt and learn over time through new data. He also noted the regulatory challenge is shared internationally, stating, “I don’t think at this moment in time we can point to a single country, a single regulatory framework, and say that they have absolutely cracked it.”
One current application of AI in UK healthcare is the use of AI-powered note-taking assistants, known as scribes, which 40% of general practitioners reportedly use to document consultations. However, research from the University of Edinburgh revealed that some patients might withhold sensitive information if they are aware that AI processes their conversations. GP and report commissioner Professor Henrietta Hughes shared that while many patients are comfortable with AI involvement during consultations, some prefer to opt out, saying, “Some say, ‘I don’t want to talk to a robot,’ and that is also fine.” She acknowledged that AI scribes are prone to errors but emphasized that it is the clinicians’ responsibility to review and correct the notes. Though AI presently assists primarily with administrative tasks and symptom identification under expert supervision, experts are optimistic about its broader potential, with ophthalmologist Professor Alastair Denniston considering AI a groundbreaking advancement comparable to antibiotics or MRI technology. Despite this enthusiasm, concerns remain about AI potentially making incorrect decisions due to biases in training data or misinformation from AI chatbots
