Call to screen stroke victims for type 2 diabetes
A call to screen stroke victims for type 2 diabetes has been issued off the back of new research.
Diabetes has already been known to be an established risk factor for stroke and could be associated with poorer outcomes after a person has experienced one, according to a new study.
However, a research team wanted to determine the prevalence of diabetes among those who had experienced acute stroke through a meta‐analysis; the association between diabetes and outcomes after ischemic and hemorrhagic stroke and to review the value of glycated hemoglobin and admission glucose‐based tests in predicting stroke outcomes.
Searches were carried out to find studies relating to diabetes and inpatient stroke populations who had been published between January 2004 and April 2017.
A meta‐analysis of the prevalence of diabetes from included studies was undertaken. A narrative review on the associations of diabetes and different diagnostic methods on stroke outcomes was carried out.
A total of 66 eligible articles met inclusion criteria. A meta‐analysis of 39 studies estimated the prevalence of diabetes to be 28 per cent (95 per cent confidence interval 26–31). The rate was higher in ischemic (33 per cent, 95 per cent confidence interval 28–38) compared with hemorrhagic stroke (26 per cent, 95 per cent confidence interval 19–33) inpatients.
Most, but not all, studies found that acute hyperglycemia and diabetes were associated with poorer outcomes after ischemic or hemorrhagic strokes: including higher mortality, poorer neurological and functional outcomes, longer hospital stay, higher readmission rates, and stroke recurrence. Diagnostic methods for establishing diagnosis were heterogeneous between the reviewed studies.
The researchers concluded: “Approximately one‐third of all stroke patients have diabetes. Uniform methods to screen for diabetes after stroke are required to identify individuals with diabetes to design interventions aimed at reducing poor outcomes in this high‐risk population.”
