METHODS • An audit of patients on three general medical wards in a mid-sized NZ hospital, to identify patients administered steroids, on six randomly selected days over a six-week period between June and July, 2015. • A self-administered questionnaire administered to doctors and nurses working on the three medical wards during the study period. RESULTS • Of the 397 patients audited, steroids were administered to 64 (16%) patients, including 38 (59%) patients administered high dose steroids (≥ 40mg prednisone or equivalent). • Only 11 (17%) patients administered steroids had their blood glucose levels (BGLs) monitored. • All patients with type 2 diabetes (n=8) administered steroids were monitored compared with only 5% of patients (n=3) without diagnosed diabetes (p<0.001). • Six (55%) patients had elevated BGLs. Data on hyperglycaemic management of patients administered steroids was limited due to the low number of patients who underwent BGL monitoring. • For the survey, a combined response rate of 63% was achieved, 71% for doctors (n=15) and 60% for nurses (n=45), The most common barriers for detecting and managing steroid-induced hyperglycaemia were the lack of clinical guidelines and insufficient knowledge of insulins. • All 15 doctors (100%) and 37 nurses (82%) reported the provision of a guideline would improve the detection and management of steroid-induced hyperglycaemia. RECOMMENDATIONS • All patients administered steroids should undergo BGL monitoring regardless of their diabetes status. Clinical guideline development and improved knowledge of insulins to treat steroid-induced hyperglycaemia may improve its detection and management.
