title: Trauma caused by falling objects at construction sites.
abstract: BACKGROUND
  Workplace-related injuries carry a significant health care challenge. The state of Qatar is developing rapidly, with much construction and an expanding industrial work force. This study aimed to assess the incidence and social impact of work-related injuries requiring hospitalization caused by falling objects at the construction sites.
  
  
  METHODS
  We performed a prospective study for all admissions, which resulted from falling objects between January 2008 and June 2010 at the only trauma center in the state of Qatar. Data were analyzed, and outcomes were described (mortality, length of hospital stay, and safety measures).
  
  
  RESULTS
  Of the total injured patients (N = 4,302) admitted between January 2008 and June 2010, 185 (4%) had injuries caused purely by falling objects. Patients' mean age was 29 years, and 97% of the patients were men. All injuries occurred at construction sites. Most patients (86%) were brought by ambulance, and the reminder was brought by private vehicles. After initial evaluation and resuscitation, 120 patients (65%) were found to have a single-system injury, and 65 (35%) had multisystem injury. Operative interventions were required in 50% of the patients. Mean length of hospital stay varied from 6.5 days for single-system injuries to 19 days for multisystem injuries. Safety devices were used in 32 patients (17.3%). All of the 16 mortality cases (8.6%) were reported in multiple injuries.
  
  
  CONCLUSIONS
  Traumatic injury caused by falling object represents a significant problem in a rapidly developing country. Many of these injuries could be prevented by following established safety guidelines.
