Introduction

Patients with diabetes are hospitalised more frequently than those without. Hyperglycaemia is associated with increased adverse outcomes and length of stay (LOS). Insulin is among the top 5 high-risk medications used in hospitals.

Objectives

To compare: (i) Diabetes prevalence at a Sydney Teaching Hospital between 2013, 2014 and 2016.      (ii) Inpatient diabetes management to plan service delivery. 

Methods

We conducted 3 single-day point prevalence surveys of all inpatient records in November 2013, 2014 and 2016. Twelve teams completed an 18-item survey on all admitted patients (n=394 2013, n=381 2014, n=368 2016). Diabetes diagnosis was ascertained if: (i) diabetes documented in medical record; or (ii) patient prescribed diabetes medication/s; or (iii) fasting glucose ≥7mmol/L; or (iv) random glucose ≥11.1mmol/L; or (v) HbA1c ≥6.5%.

Results

Diabetes prevalence was 20-25%. In 2016, highest prevalence was found in Heart/Lung Transplant (59%) and Heart Failure (50%). As outlined in the Table, the majority were male and had type 2 diabetes. Half received subcutaneous insulin during admission and many experienced at least one insulin prescription/administration error. In the 7-days preceding the survey, hyperglycaemia occurred on >10 occasions in one quarter of patients and hypoglycaemia occurred on ≥ 1 occasion in 11-13% of patients. Of the diabetes patients who met referral criteria, only half-to-two-thirds were referred.

Conclusions

One-quarter of hospital patients have diabetes. Half are treated with insulin during admission. Insulin errors are common. Diabetes inpatient teams are underutilised.
