People with diabetes account for 15% of inpatients in England, according to an audit published by NHS Diabetes. Analysing clinical data of over 12,000 inpatients with diabetes from 206 hospitals as well as nearly 5,000 patient questionnaires, the ‘National Diabetes Inpatient Audit (NaDIA) 2010 (England)’ also found that at the time of the audit people with diabetes had been in hospital for an average of eight days, approximately three days longer than all inpatients. Nearly all (86.7%) were admitted as an emergency.
The audit also discovered that over one third (37.1%) of inpatients with diabetes experienced at least one medication error, a quarter (26.0%) of their charts had prescription errors and a fifth (20.0%) had one or more medication management errors. Insulin overdoses can result in potentially fatal hypoglycaemic episodes (‘hypos’) and insufficient insulin can lead to diabetic ketoacidosis (DKA) which, if left untreated, can also prove fatal.
The audit found that patients with medication errors had twice the rate of severe hypoglycaemia (18.1 vs 7.9%). Of further concern, whilst in hospital 44 people (0.4%) developed DKA and 266 (2.4%) had hypoglycaemia severe enough to require injectable treatment.
