Effect of online diabetes training for hospitalists on inpatient glycaemia

Aim An online diabetes course for medical residents led to lower patient blood glucose, but also increased hypoglycaemia despite improved trainee confidence and knowledge. Based on these findings, we determined whether an optimized educational intervention delivered to hospitalists (corresponding to an Acute Physician or Specialist in Acute Hospital Medicine in the UK) improved inpatient glycaemia without concomitant hypoglycaemia.

Methods All 22 hospitalists at an academic medical centre were asked to participate in an online curriculum on the management of inpatient dysglycaemia in autumn 2009 and a refresher course in spring 2010.

Results All hospitalists completed the initial intervention. Median event blood glucose decreased from 9.3 mmol/l (168 mg/dl) pre-intervention to 7.8 mmol/l (141 mg/dl) post-intervention and 8.5 mmol/l (153 mg/dl) post-refresher (P <0.001 for both). Hospitalizations categorized as hyperglycaemia decreased from 83.3 to 55.6% (P = 0.014), with a trend towards euglycaemia (10-28.9%, P = 0.08) and no change in hypoglycaemia. Hyperglycaemic patient-days decreased from 72.0 to 57.3% (P = 0.004), with greater target glycaemia (27.3-39.4%, P = 0.016) and no change in hypoglycaemia.

Conclusions An optimized online educational intervention delivered to hospitalists yielded significant improvements in inpatient glycaemia without increased hypoglycaemia.
