Objective: Glucose is measured on hospital admission as an emergency as elevated glucose is associated with an eight-fold risk of dying in hospital. This study reports on admission plasma glucose by ethnicity in people without prior diabetes.

Research Design and Methods: A clinical audit CARMS-12031 of electronic patient records for 113,097 admissions to hospital over 1 year from April 2014 to March 2015 identified 43,201 emergency admissions with glucose unavailable for 11,274 (26%). Of 5,867 admissions with prior diabetes coding, 5,523 (94%) had glucose recorded. First attendances were analyzed for emergency admissions with no record of diabetes.

Results: Of these 18,965 people admitted, 75% were White Europeans WE who were older than South Asians SA 12%, unknown/other ethnic groups U 9%, and Afro-Caribbeans AC 4%. 1,003 people admitted as an emergency had glucose in ‘diabetes range’ (≥11.1mmol/L) and 3,042 in ‘at risk’ range (7.8 to 11.0mmol/L). More SA 8% had glucose in diabetes range than WE 5% and also than U 5%; there were significantly more WE 17% in ‘at risk’ range than U 14% or AC 11%. Higher glucose was observed in SA and U men than women, p = 0.005 and p = 0.018, respectively.

Conclusions: Protocols should target people requiring additional HbA1c testingto diagnose undiagnosed diabetes on hospital admission especially younger SA and AC individuals, and outline appropriate clinical intervention.
