Abstract W P154: Increase in the Rate of Comorbid Diabetes in Stroke Hospitalizations From 1998 to 2011: The National Inpatient Sample
Due to the obesity epidemic in the US Population, there has been a related increase in type 2 diabetes. We sought to examine the trend within patients hospitalized due to stroke in a representative population.
Methods: Using data from 1998 through 2011 from the National Inpatient Sample (NIS), we aimed to see the trends in diabetes for patients hospitalized with a primary discharge diagnosis of stroke (SAH (ICD code 430), ICH (ICD codes 431 and 432.9) and Ischemic (ICD codes 433x1, 434.11and 434.91). Secondary ICD codes were used to define diabetes. Hospitalizations used in this analysis included patients aged 20 years and over at date of admission.
Results: For the 14 years examined, there were a total of 1,360,839 records with primary diagnosis of stroke, distributed as; 5.4% SAH, 15% ICH, and 79.6% Ischemic. The sample was 46% male; and 29% had diabetes (93% type 2). The rate of diabetes for each stroke subtype was: 12.2% SAH, 22.2% of ICH, and 31.5% of Ischemic. The proportion of stroke discharges with diabetes showed a significant increase with time, with a year over year increase in 12 of the 13 periods, from 26.5 in 1998 to 30.0 in 2011.
Conclusions: The proportion of patients hospitalized for stroke who had comorbid diabetes continue to increase year over year, with almost one third of patients hospitalized for Ischemic stroke also having diabetes in 2011. This suggests that control of diabetes, and associated reduction of obesity may lead to reduction of stroke in the US.
