Abstract T P376: Trends in Hospitalization for Non Traumatic Pediatric Stroke from 1997 to 2009: The Kids’ Inpatient Database
Introduction: Pediatric stroke is known to be a small proportion of all strokes seen in the US. There has been little recent publication of temporal trends in hospitalization rates due to stroke in children. The Kids’ Inpatient Database (KID) is a sample of pediatric discharges available from community non-rehabilitation hospitals collected every 3 years (2,521 hospitals in 1997 to 4,121 hospitals in 2009, the most recent year in this study).
Methods: Using data on children less than 19 years of age from KID for the years 1997, 2000, 2003, 2006, and 2009, we wanted to examine whether rates and costs of stroke related hospitalizations have changed over time. Only the primary discharge diagnosis was considered for hospitalizations due to stroke. Hospitalizations having a secondary diagnosis of traumatic brain injury and those with a secondary diagnosis of in-hospital birth were excluded. Stroke was defined for this study as ICD-9 codes of 430.xx, and 431.xx (hemorrhage); and 433.xx, 434.xx, and 436 (ischemic, IS). SAS® survey software was used to determine the appropriate weighted variances and estimates, due to the KID sampling scheme. Trends in rates over time were assessed using the Cochran-Armitage test.
Results: For the five years sampled between 1997 and 2009, there were 8841 estimated hospitalizations with a primary diagnosis of stroke, out of 13,643,666 total estimated hospitalizations. Estimates for pediatric hospitalizations due to hemorrhage increased from 28/100,000 to 31/100,000 (p<.01) between 1997 and 2009. For IS, the hospitalization rate increased from 30/100,000 to 37/100,000 (P<.001). Combined rates increased from 59/100,000 to 68/100,000 (p<.0001). The average total charge for a hospitalization due to hemorrhage increased from $66,800 in 1997 to $149,000 in 2009. Charge for an IS hospitalization increased from $28,000 in 1997, to $75,600 in 2009. All charges are expressed in 2009 dollars.
Conclusion: Cost per pediatric hospitalization with a primary diagnosis of stroke more than doubled between 1997 and 2009. There was an increase of 15% in the rate of pediatric hospitalizations with diagnosis of stroke in the same time period. Whether this change is due to changes in coding, or an increase in stroke incidence needs to be investigated further.
