The latest release of the NHS online appointments system, Choose and Book 4.0, went live over the weekend after a delay to its original launch date.
NHS told Computerworld UK that the system, which is part of the £12.4 billion Connecting for Health programme, went live following an announcement late on Friday that it would be switched on at the weekend.
Choose and Book 4.0 was originally due to go live in mid-April, but the NHS decided to delay its launch after a problem with the original system meant hundreds of patients received the wrong appointment details.
In a statement, the NHS said: “The issue, affecting a relatively small number of patient bookings, which led to the postponement of Release 4.0, has been resolved.”
An automated system has now been put in place “to quickly identify any further recurrence” of the error, it added, saying that there was “no evidence” to suggest patient safety had been compromised.
On the new version of the system, patients can choose to be referred to hospitals across the country.
Last week the government announced that expenditure on the system had nearly hit £100 million and additional service costs had overtaken core expenditure. But it said the programme was "within the budget for the original business case".
