  1. The Barell Body Region by Nature of Injury Diagnosis Matrix Aharonson-Daniel L Presenting the work of the late Vita Barell in conjunction with Avitzour M, Boyko V, Ziv A, Heruti R, Abargel A, ISRAEL Mackenzie E, Fingerhut L, USA And many dear friends from the ICE on Injury The Center for Trauma and Emergency Medicine Research, Gertner Institute for Epidemiology and Health Policy Research, Israel

  2. What is the Matrix? The Matrix is a tool for classifying injury ICD-9-CM codes by body region and nature of injury. It is useful for standardized retrieval of injury cases for epidemiological, clinical and management oriented analyses.

  3. Matrix objectives • To simplify the process of classifying injuries • To provide a standard format for reports • To serve as a standard for casemix comparison • To characterize the patterns of injury

  4. Motivation for building the matrix ICD 9-CM CODES 800-995 Sorted bynature of injury Detecting injuries bybody region requires collating codes across chapters

  5. Motivation for building the matrix ICD 9-CM CODES 800-995 nature of injury body region

  6. The Matrix structure Nature of injury Body Region ICD-9-CM injury codes

  7. Nature of injury (Columns) are based on Sequenceof codes in ICD-9-CM codebook 12 Nature of Injury Columns Fractures, dislocations, sprains & strains, internal, open wounds, amputations, blood vessels, contusions/superficial, crush, burn, nerves unspecified

  8. Body Region (Rows) are based on : Anatomic subgroups High Incidence Variability in Outcome Difference in health care utilization 3 standard levels of detail 5 rows 10 rows 36 rows

  11. Example Fractures Internal Blood Vessels Head 800.4 Skull fracture 850 Concussion Spinal Cord 860 Flail chest Chest 824 Fractured ankle Lower extremity Jack – skull # Jill - concussion John – Flail chest Peter - # ankle

  12. Summary Report Number % Head (50) 2 0 (0) Spinal Cord 1 (25) Chest 1 (25) Lower extremity 4 Total N 100

  13. Summary report in practice

  14. Using report for comparisons

  15. Forthcoming developments Collaboration with CDC NCIPC, academic and other Neurological organizations about the structure and interpretation of Severity of TBI rows Develop standard methods for summarizing multiple injuries Translate into ICD-10

  16. Thanks for your attention A handout of the matrix is available The matrix is also on the net at: www.cdc.gov/nchs/projects/barellmatrix.htm
