Doctors have received millions of pounds in payment for patients who have moved practice, died or been forced to leave the country, according to a new report.

A one-year review by the Audit Commission identified more than 95,000 patients who needed removing from GP lists in England and Wales.

They included almost 30,000 patients who had moved to another practice (31 per cent of the total), more than 32,000 who had died years before (34 per cent) and almost 10,000 failed asylum seekers (10 per cent).

Nearly 20,000 patients (21 per cent) were also removed from lists after investigators found high numbers of people registered at the same property.

While it would not be unusual for 50 patients to be registered at a nursing home, 20 patients registered in one house would suggest inaccurate GP lists, they said.

Of those patients who had died but were still on GP lists at the time of the review in 2009-10, 157 died before 1980.

They included one patient whose GP continued to be paid for their care for around 40 years despite the fact they died in 1969.

A further 335 patients had been on lists for up to 30 years despite dying between 1980 and 1990, while another 429 had died between 1990 and 2000.

Inaccurate GP lists can mean some practices receive more than their fair share of funding, while others miss out.

When patients move to another practice, failing to remove them from an existing list can also mean two GPs being paid for one patient’s care.

GP practices are paid £64.59 for each patient on their list. Today’s report said the removal of more than 95,000 “ghost patients” meant the NHS had been able to save more than £6.1m in one year.

Following the review - known as the National Duplicate Registration Initiative exercise - the medical records of almost 30,000 patients were transferred from patients’ former GP to their current one.

It is the job of primary care trusts in England and local health boards in Wales to keep an up-to-date list of patients.

Overall, the 95,000 patients represent around 0.16 per cent of the population.

Andy McKeon, managing director of health at the Audit Commission, said: “The NHS and GPs generally manage patient lists well - at any one time there are some 58 million records and many movements on and off lists.

“However, the NDRI, and active follow-up locally of duplicates and other anomalies, has resulted in £6.1m annual savings.

“It is disappointing that some areas did not rigorously follow-up the information provided by NDRI, which would have resulted in more savings.”
