Objectives:
Literature from stroke and cardiac hospital admissions demonstrate a higher prevalence of undiagnosed type 2 diabetes compared with the general population. Fewer diabetes screening studies exist in the general medicine population, none of which have been based in Canada. Our primary objective in this study was to determine the prevalence of probable undiagnosed diabetes (glycated hemoglobin [A1C]≥6.5%) in hospitalized medicine patients. Secondary objectives were to identify the prevalence of undiagnosed dysglycemia (A1C≥6.0%) and the subsequent management of emergent cases.
Methods:
In this prospective cohort study, adult patients admitted to internal medicine at a tertiary hospital in Ontario were screened for diabetes using an A1C test over a 3-month period. Baseline demographics and outcomes were compared using t tests, chi-square tests and Fisher's exact tests for normoglycemia, undiagnosed dysglycemia and probable undiagnosed diabetes. A regression analysis was performed to identify any relationships between various cardiovascular-related risk factors and A1C.
Results:
A total of 53 adult patients were enrolled. The prevalence of probable undiagnosed diabetes and undiagnosed dysglycemia was 7.5% (n=4) and 30.2% (n=16), respectively. Implementation of diabetes management strategies and/or documentation of the finding occurred in 4 of 16 patients. Regression analysis showed no relationship between either cardiovascular-related risk factors or admission glucose with A1C.
Conclusions:
A broader screening approach may capture previously undiagnosed cases of diabetes that do not belong to traditionally at-risk populations. Future studies should focus on identifying risk factors for undiagnosed dysglycemia in hospitalized patients, including ethnicity and barriers to community access, so that appropriate screening programs can be developed.
