Summary:After a fall, the distance fallen is sometimes used to predict the injury severity. We aimed to examine how distance fallen performs as a predictor of major injury. A cohort of trauma victims attending our emergency department after having fallen from a height was identified retrospectively, and data were collected regarding the fall and injuries sustained. Performance of threshold heights, ranging from 2 meters (6.6 feet) to 10 meters (32.8 feet), as a diagnostic test for major injury was assessed. Height fallen performed poorly over the range of thresholds used. At low thresholds, sensitivity was inadequate to rule out major trauma, whereas the low prevalence meant that, despite impressive specificity at higher thresholds, positive predictive value was poor. At the optimal threshold of 5 meters (16.4 feet), the positive predictive value was 0.17 and sensitivity was 0.33. Height of fall is a poor predictor of major injury.
