A tragic case of a paracetamol overdose has sparked a crucial conversation about the role of prescribing system alerts in patient safety. The potential consequences of disabling these alerts are now under scrutiny, as they may have contributed to a preventable death.
NHS England has suggested that the death of Paula Doreen Hughes, a 55-year-old patient, could have been avoided if certain decision-support alerts were not disabled in the hospital's prescribing system. Hughes suffered a fatal overdose of paracetamol due to a medication error, as reported by Liliane Field, the assistant coroner for Inner South London, in a prevention of future deaths report (PFD) published in December 2025.
But here's where it gets controversial: both NHS England and the Royal Pharmaceutical Society (RPS) emphasized that while these alerts are crucial safety features, they should not replace the professional responsibility of clinicians. They argue that frequent alerts can lead to 'alert fatigue', desensitizing users and increasing the risk of overlooking critical warnings.
The PFD was sent to various organizations, including Lewisham and Greenwich NHS Trust, who responded swiftly and commendably by introducing measures to prevent such incidents in the future. They implemented changes in their electronic prescribing system to eliminate concurrent prescriptions of paracetamol-containing drugs and reduce therapeutic excesses based on weight.
NHS England acknowledged that their electronic prescribing systems can alert clinicians about potential overdoses, but in this case, it is assumed that the alert feature was not enabled. They stated, "Had this feature been enabled, there is a reasonable likelihood that the error would have been prevented."
And this is the part most people miss: NHS England's self-assessment toolkit, 'ePrescribing Risk and Safety Evaluation' (ePRaSE), includes therapeutic duplication as a theme to test the effectiveness of e-prescribing systems. They plan to prioritize this incident in the review of scenarios for the next release in 2026.
IT system suppliers, Oracle and Cerner, confirmed that their system offers alert notifications to protect against paracetamol overdosing. However, they emphasized that it is up to NHS trusts to decide whether and how to enable these features.
The RPS, in their response to the coroner's report, suggested that national oversight is needed to coordinate work with secondary care system suppliers to build alerts and warnings for unacceptable medication duplication. They stressed that electronic systems do not replace the personal responsibility and accountability of healthcare professionals.
A spokesperson for Lewisham and Greenwich NHS Trust expressed their condolences and noted the findings from the PFD, committing to taking steps to prevent such incidents in the future. Their response is available online, outlining the trust's commitment to patient safety.
This case highlights the delicate balance between utilizing technology to enhance patient safety and ensuring that clinicians remain vigilant and accountable. It raises important questions: Should we rely more on technology to prevent errors, or is human oversight and judgment still paramount? What measures can be taken to ensure that alert systems are utilized effectively without causing alert fatigue?
