Injury severity score, resource use, and outcome for trauma patients within a Japanese administrative database.

摘要: BACKGROUND:: Injury Severity Score (ISS) is commonly used in prediction models and risk adjustment for mortality. However, few studies have assessed the relationship of ISS to outcomes such as resource use. To test utility investigation quality trauma care, we evaluated impact on utilization METHODS:: Of 1,895,249 cases from a Japanese administrative database 2006, 13,627 patients with were analyzed. Variables included demographics, ISS, number locations injured organs, comorbidities, diagnostic therapeutic procedures recorded during hospitalization, hospital type. Dependent variables length stay (LOS), total charges (TC), initial 48-hour TC, high outliers LOS or Multivariate analyses measure ISS. RESULTS:: 1 9 was most frequent (85.5%) blunt injury occurred 93.7% patients. With increasing mortality rate rose 27.2% at >/=36. higher >/=36 whereas TC 25 35. After controlling study variables, rehabilitation strongly associated LOS, outliers. 35 affected most, while ventilation most. "Abdomen, pelvic organs" more outcomes. CONCLUSIONS:: Specific organs may be estimate use monitoring care. integrate efficient system variations input among hospitals should investigated. Language: en
