Injury Related Hospitalizations in Wisconsin, 1994-1999
Wayne Bigelow, Director Wisconsin CODES Project Ctr. For Health Systems Research & Analysis UW-Madison May 4, 2001
Methods
• Presentation can be found at: www.chsra.wisc.edu/codes • Wisconsin Hospital discharge data for 1994-1999 was used. • Discharges with an E-Code which did not relate to “adverse therapeutic drug effects” or to misadventures associated with a hospital stay were included in the data.
Methods 2
• Discharges with an E-Code were selected for inclusion in the analysis. • However, discharges for which the E-Code indicated hospitalizaton due to “adverse therapeutic drug effects” or to adverse effects associated with a hospital stay or other medical care were excluded from the analysis. • Classification details for cause of injury can be found in: “Recommended Framework for Presenting Injury Mortality Data” in MMWR, August 29, 1997 (46:RR14; 1-30) or on the internet at: www.cdc.gov/epo/mmwr/preview/mmwrhtml/00049162.htm
Goal
• To determine the scope and cost of injury related hospitalizaitons in Wisconsin. • To look at the distribution of specific causes of injuries and “intent underlying injuries”. • To evaluate both the source of injury related hospital admissions and the discharge status of such admissions. • To evaluate demographic (sex & age) differences in cause of injury and underlying intent of injury.
