Background and Aim: Approximately 1500 people attend the Beacon Health Check Department annually involving a panel of blood tests being screened. Our aim was to compare what percentage of this asymptomatic population have diabetes or were pre-diabetic and what percentage of these were undiagnosed and therefore untreated conditions.

Methodology: This audit was a retrospective review of data collected from patients attending the Beacon Hospital Health Check Department during 2019. The data was applied for through the Beacon Hospital IT Department in excel format and screened by location. Void samples were excluded. In the case of HbA1c values, patients found to be in pre-diabetic or diabetic ranges as per WHO guidelines (43-47 and >48 mmol/mol) (Auto-analyser: Architect ci8200) had their Health check discharge letters retrieved to determine if the condition was a new or known diagnosis.

Results: • 1577 were examined, 14 had HbA1c values in the pre-diabetic range (0.89%).

• 13 patients had HbA1c values in the diabetic range (0.82%)

• 3 of 14 patients in the pre-diabetic range were known, 11 were newly diagnosed (0.70%).

• 7 of 13 patients found to be in the diabetic range were known, 6 were new diagnoses (0.38%)

• Our age range included patients from 19 to 86-years-old with a mean of 48+/- SD. 10

• Age 45+ only results: 996 patients total with 3 newly diagnosed diabetics (0.30%).

Conclusion: • Data on undiagnosed prevalence of diabetes is scarce. According to our literature review, prevalence over the age of 45+ is 3.5%.

• Our overall results were substantially lower than this with 0.38% receiving new diabetic diagnoses.

• Excluding results outside of the age range documented in our literature review failed to correct for the variation in the data.

• With an observed frequency less than 1% being newly diagnosed with diabetes, these findings were lower than expected given the prevalence in the community.
