A hospital trust had 2,000 patients wait more than a year for elective treatment, HSJ can reveal.
From September 2014 to April this year Barts Health Trust in London saw thousands of patients who had waited 52 weeks.
The large trust had stopped reporting its waiting times performance during this period and HSJ last week reported a probe ordered into performance on elective waiting times was not completed.
A spokesman last week confirmed that harm reviews were being carried out into the 2,000 cases but so far no patients were found to have died or come to severe or moderate harm “as a result of late treatment”.
The trust also assessed whether harm had come to another group of patients, those considered particularly high risk. It would not say what the result of these assessments had been, saying a report would come to the board when the trust had cleared its remaining long waiters.
The previous record for highest number of patients waiting more than a year for treatment was held by Barking. Havering and Redbridge University Hospitals Trust which revealed 1,015 in 2016.
In the latest waiting times data, for April, the trust had 36 patients waiting more than a year for treatment, part of a national total of 2,767.
Commissioners can impose a £5,000 fine for each patient waiting more than a year, which would have left Barts open to a potential £10m penalty had it been reporting its data.
In 2015, the trust commissioned a report from investigatory firm Verita into why its action plan to improve elective performance in early 2014 had not worked.
But this week it said it did get replies from former employees, but that the staff contacted had disagreed with the report.
A spokesman said in a statement: “The detailed findings of the review were disputed by a number of individuals during the initial efforts to secure right of reply.”
In the first half of 2015 the trust saw the resignations of the chief executive, chair, chief nurse, medical director and finance director.
The trust spokesman added: “It is no secret that there was a significant turnover of senior staff during this period and that there were major challenges for the trust to overcome regarding quality of care, performance and finance.
”In light of this the trust leadership, having received the recommendations from the review, decided to prioritise fixing the issues at hand based on the recommendations rather than spending the significant additional time and resource necessary in order to finalise the detail within the review.”
He said the trust would not share the draft report.
