The 16 trusts forced to retest thousands of patients

The full list of 16 trusts which are retesting tens of thousands of patients who may have been wrongly diagnosed with diabetes can be revealed by HSJ.

Concerns about over-diagnosis first emerged last year, linked to problems with a device used to monitor glucose levels. But NHS England has so far declined to identify all the trusts involved.

Now, HSJ  has checked accreditation certifications to confirm which trusts use the Premier Hb9210 HbA1c analyser, manufactured by Trinity Biotech, and can reveal the full list for the first time.

They include several trusts not previously linked with the issue in public: Calderdale and Huddersfield Foundation Trust; Mid and South Essex FT; Airedale Hospitals; University Hospital Bristol and Weston FT; Stockport FT and Hull University Teaching Hospital Trust.

They join nine others who are publicly known to have been impacted following HSJ’s coverage last year, or information posted online. These are Norfolk and Norwich University Hospitals FT; South Tees Hospitals FT; York and Scarborough FT; West Hertfordshire Teaching Hospitals Trust; Maidstone and Tunbridge Wells Trust; Barking, Redbridge and Havering University Hospitals Trust; Chesterfield Royal Hospital FT; and County Durham and Darlington FT.

The Medicines and Healthcare products Regulatory Agency said in a notice in July it had received reports of a positive bias in results which have resulted in patients being incorrectly diagnosed as pre-diabetic. It said the manufacturer would update its instructions to clarify frequency of preventative maintenance required.
