Around 127,450 patient referrals for specialist National Health Service (NHS) hospital care disappeared from an electronic booking system in England between February and July this year, an official safety watchdog has found.
A report by Health Services Safety Investigations (HSSIB) revealed that thousands of patients awaiting specialist care, clinical guidance or medical advice vanished from the NHS e-Referral system (e-RS) before hospitals looked at their cases. As a result, those patients may have been left waiting at home for appointments and treatment that never arrived.
Doctors described the flaw in the electronic system as "dangerous" and warned that some patients will have seen their health worsen considerably during the wait. Dr Dean Eggitt, a senior general practitioner (GP) in Doncaster, South Yorkshire, told the Daily Mail: "This will contribute to patients feeling even more unwell, or possibly even death if they're not seen when they need to be."
How the 180-day referral rule works
The e-RS is the digital platform used by GPs and other primary care professionals across England to refer patients to hospital specialists for further investigation. Within the NHS structure in England, family doctors serve as the main gateway to secondary care, meaning patients typically rely on an electronic GP referral to see a hospital consultant or undergo specialist diagnostic tests.
According to the HSSIB report, 12.4 million referrals and requests for specialist advice were submitted through the system between February and July. During that same six-month period, more than 1.3 million entries were automatically removed after sitting in the system for more than 180 days.
NHS England stated that most of those 1.3 million removed records had likely already been reviewed or processed by hospital staff. However, the watchdog found that around 127,450 of the deleted entries were new referrals that hospitals may never have examined, leaving those patients likely waiting to hear about an appointment.
Rising waiting lists and system pressure
The technology contains a built-in 180-day rule that automatically deletes referrals after six months if no action has been taken. Health officials introduced this mechanism in 2004 to prevent a backlog of unprocessed referrals, at a time when hospital waiting lists were far shorter than they are today.
Concerns have grown over mounting pressure on the digital platform, with the number of referrals rising by around 40 per cent between 2019 and 2025. Currently, almost 7.4 million people are awaiting routine hospital care in England, including more than 113,000 patients who have waited more than a year.
The HSSIB, an independent statutory body that investigates patient safety risks across England's health service, said this excess demand has increased the risk of patients "dropping off" the electronic system. Investigators noted that the problem only came to light after GPs raised concerns that their patients had not heard from the specialist services to which they had been referred.
Previous referral failures and patient harm
Although the watchdog found no evidence of direct harm to patients, it could not rule out that some patients' medical conditions worsened while they waited. Because of those delays, affected individuals may have needed more aggressive treatment than if specialists had seen them sooner.
The investigation also uncovered several similar incidents dating back years. One case in 2018 involved 72 referrals vanishing from the system, while another in 2019 saw more than 1,000 patients "potentially" drop off a hospital waiting list. Between 2023 and 2024, health staff had to reinstate another 1,000 patients after their records "disappeared".
Rachel Power, chief executive of the Patients Association, an independent healthcare charity that campaigns for patient rights in the United Kingdom, said patients regularly feel "forgotten by the NHS". "The public should not have to worry that the NHS will lose track of them," she continued. "Managing referrals is too often treated as an admin task, but it is part of patients' clinical care and when it fails, people can come to real harm."
NHS England updates referral guidance
NHS England, the executive body that oversees the day-to-day operations of the health service in England, told the HSSIB that the e-RS was not designed for the volume of referrals it now receives. It said it would update official guidance on the risks of the 180-day rule and share the revised instructions with local healthcare providers.
"But no one should ever wait 180 days for their referral to be processed in any circumstance," the health service added in a statement.
"NHS guidance is clear that e-Referral services should not be used to manage waiting lists and we are working with NHS trusts to ensure they identify patients who are waiting the longest and take appropriate action to get them the care they need."
