The lead clinician for the National Diabetes Inpatient Audit, Dr Gerry Rayman said the purpose of the audit is to "drive improvements in care for inpatients with diabetes". He added:
I am pleased to see there has been some progress on problems highlighted in previous years' reports, for instance around insulin prescribing.
But staffing levels remain low, and it is of grave concern that some patients are developing DKA, which is a potentially life-threatening complication in hospital. This is due to their needs being neglected and should simply never happen.
Bridget Turner, director of policy and care improvement at Diabetes UK, said that "even a single" case of ketoacidosis developing in hospital is "unacceptable" as it suggests insulin "has been withheld from that person for some time".
The fact that this is regularly happening raises serious questions about the ability of hospitals to provide even the most basic level of diabetes care.
In every aspect of hospital diabetes care that this report shines a light on, the picture that emerges is profoundly disturbing.
Medication errors are being made with alarming regularity, large numbers of people are not getting foot checks that we know can help prevent amputation, while one in 10 people's blood glucose level is dropping dangerously low during their hospital stay.
Put together, this adds up to a situation where in too many cases hospitals are doing people with diabetes more harm than good.
