PERFORMANCE: Whipps Cross University Hospital Trust last month began an investigation into a computer system failure that resulted in more than 100 blood tests not being processed.

The trust’s August board papers note that delays were found with tests for three patients, which prompted an investigation that discovered a total of 108 patients had been affected.

A switch from a manual to a computerised system was identified as the cause. The north east London trust reported it would contact the affected patients and their GPs, as well as setting up a helpline.

A report on serious incidents at the hospital said: “Until all the tests are completed we will not know the full outcome of this incident. The system failure and governance assurance processes are being investigated fully.”

The report also highlighted the case of a surgical swab being left inside an ear, nose and throat patient in July. The report said: “The patient coughed up a blue gauze swab approximately three hours after surgery.

“The ENT team was informed and the patient was monitored closely. The patient was discharged three days later, not having suffered any ill effects.”
