Introduction: This study was conducted to examine the characteristics of intentional fall injuries and the factors associated with their prognosis., Methods: The study included 8992 patients with unintentional falls from a height (nonintentional group) and 144 patients with intentional falls from a height (intentional group). General and clinical characteristics were compared between the 2 groups. Intentional fall cases were divided into severe and nonsevere groups, and the factors associated with severe injury were evaluated by comparing these groups., Results: The most common age group was younger than 14 years in the nonintentional group and between 30 and 44 years old in the intentional group. For the nonintentional group, 65% of the patients were male, and 48% were male in the intentional group. Fall heights of more than 4 m were most common in the intentional group. Discharge was the most common result in the nonintentional group; however, death before arrival at the emergency department (ED) or during ED treatment occurred in 54.9% of patients in the intentional group. In the severe injury group within the intentional group, patients were older, and the height of the fall was higher. Factors associated with severe injury in the intentional group included being a high school graduate rather than a college graduate and greater fall height., Conclusion: The risk of severe injury increased with fall height in the intentional group, and a high school level of education rather than a college level of education was associated with more severe injury., (Copyright © 2014 Elsevier Inc.

Objective: The purpose of this study was to assess the ability of the International Classification of Diseases-based Injury Severity Score (ICISS) to detect preventable deaths, and to compare the performance of trauma care facilities., Methods: For 2 years, from 1997 to 1998, 131 trauma deaths and 1,087 blunt trauma inpatients from 6 emergency medical centers (EMCs) in Korea were reviewed. Trauma deaths were reviewed and the preventability of those deaths was judged by two professional panels. For both trauma deaths and trauma inpatients, the survival probability of each trauma patient was assessed using the ICISS full model. The degree of agreement in the preventability of trauma death between survival probability on the basis of the ICISS and judgment rendered by professional panels was determined, and the correlation between the W-score and the preventable death rate in each EMC was also assessed., Results: The overall agreement rate between ICISS survival probability and preventable deaths judged by professional panels was 66.4% (kappa statistic, 0.36), and the positive predictive value of the ICISS in detecting preventable trauma deaths was 54.1% and the negative predictive value was 84.8%. The Spearman correlation coefficient between the W-score and the preventable death rate by each EMC was -0.77 (p = 0.07)., Conclusion: The degree of agreement in the preventability of trauma death derived from the ICISS with a professional judgment on preventability was similar to that derived from the Trauma and Injury Severity Score. The W-scores of EMCs correlated well with their preventable death rates, with marginal statistical significance. This study has demonstrated that the ICISS is useful in detecting preventable deaths and in comparing the performance of trauma care facilities.
