Thousands of hospital patients suffering from diabetes are at risk of potentially fatal low blood-sugar levels after medication blunders by doctors.
According to the report, hospitals in England and Wales made 3,700 medication errors in a week.
If this one-in-three level of mistakes - which can lead to dangerously high blood-glucose levels - continued for a year, it could affect 208,000 patients, the Daily Express reported.
During a seven-day period, patients with blunders suffered more than double the number of severe hypoglycemic - or hypo - episodes com- pared to those treated accurately.
Hypos occur when blood-glucose levels drop severely low - and if left untreated can lead to seizures, coma or death.
"It is unacceptable for any person in hospital to receive inade- quate care," Barbara Young, chief executive of Diabetes UK, said.
"Urgent action is needed to make sure that general ward staff are competent in treating in-patients."
The National Diabetes Inpatient Audit analyzed data for 19,400 patients over seven days last October.
Results revealed that 32.4 per cent of patients in England had experienced at least one medication error during the previous seven days - down from 36.6 per cent the previous year.
The audit also found that 68 patients developed diabetic ketoacidosis, which can be fatal if not detected. This occurs when blood-glucose levels are consistently high, indicating insulin treatment was not given for a significant period.
"The majority of hospital doctors and ward nurses still do not have basic training in insulin management and glucose control," Audit lead clinician Dr Gerry Rayman said.Medicine management has improved since 2010 but there are still too many errors. We will continue to work with clinicians to reduce these," The Health Department said.
