A computer problem affecting thousands of hospital patients has not led to anyone coming to harm, the NHS said.
Last September, East & North Hertfordshire NHS Trust found 14,600 patients may have been discharged, mainly in Stevenage, without medical notes being sent to them or their GP.
The notes of a “statistically significant sample” of data were analysed, the trust said.
A spokesman said: “The data showed no harm to patients.”
East and North Hertfordshire NHS Trust runs:
The Lister Hospital in Stevenage the new QEII Hospital in Welwyn Garden City Hertford County Hospital Mount Vernon Cancer Centre, Northwood
The patient record system, Lorenzo, was introduced at The Lister in September 2017 and the Trust earlier said most people affected were in-patients there.
Discharge summaries are sent to GPs and
