Fall-related traumatic brain injury deaths and hospitalizations among older adults--United States, 2005.

PROBLEM: Among older adults, both unintentional falls and traumatic brain injuries (TBI) result in significant morbidity and mortality; however, only limited national data on fall-related TBI are available. METHOD: To examine the relationship between older adult falls and TBI deaths and hospitalizations, CDC analyzed 2005 data from the National Center for Health Statistics' National Vital Statistics System and the Agency for Healthcare Research and Quality's Nationwide Inpatient Sample. RESULTS: In 2005, among adults>or=65 years, there were 7946 fall-related TBI deaths and an estimated 56,423 hospitalizations for nonfatal fall-related TBI in the United States. Fall-related TBI accounted for 50.3% of unintentional fall deaths and 8.0% of nonfatal fall-related hospitalizations. SUMMARY: These findings underscore the need for greater dissemination and implementation of evidence-based fall prevention interventions.

Epidemiology of cervical spine injury victims.

STUDY OBJECTIVE: We sought to characterize demographics and injury patterns among patients undergoing emergency department cervical spine radiography for blunt traumatic injury. METHODS: All patients with blunt trauma undergoing cervical spine radiography at 21 centers were enrolled in this prospective, observational study. Patients' date of birth, age, sex, and ethnicity were noted before cervical spine radiography. RESULTS: Demographic factors associated with cervical spine injury, present in 818 of 33,922 patients, included the following: age of 65 years or older (relative risk [RR] 2.09; 95% confidence interval [CI] 1.77 to 2.59); "other" ethnicity (RR 1.79, 95% CI 1.46 to 2.19); male sex (RR 1.72, 95% CI 1.48 to 2.00); and white ethnicity (RR 1.50, 95% CI 1.31 to 1.72). Hispanic ethnicity (RR 0.64, 95% CI 0.51 to 0.79), female sex (RR 0.58, 95% CI 0.50 to 0.67), black ethnicity (RR 0.55, 95% CI 0.45 to 0.66), and age of less than 18 years (RR 0.39, 95% CI 0.27 to 0.55) were associated with reduced risk of cervical spine injury. CONCLUSION: Among patients undergoing ED cervical spine radiography, cervical spine injury is more common among the elderly, male subjects, and patients of white or "other" ethnicity. Because cervical spine injury occurs in patients in all demographic categories, however, this information cannot be used to select individual patients who should or should not undergo imaging.
