Gender Difference in Fall among Adults Treated in Emergency Departments and Outpatient Clinics

Feifei Wei and Amy L. Hester

Background: This study examined the impact of gender on age-related increase for falls and injurious falls resulting in head injuries/fractures among adults, using data from both emergency department and clinic visits. We also estimated the percentages of falls treated in points of entry outside of emergency departments.

Methods: The study population consisted of 259,611 adults seen at emergency department, inpatient, and/or outpatient facilities between January, 2007 and June, 2012 at a US medical center. Rates of falls and injurious falls with head injuries/fractures were calculated by age and gender.

Results: After using both emergency department and clinic visit data, medically consulted falls and injurious falls resulting in head injuries/fractures increased with age for females aged ≥ 18 years. For males, these rates declined, reached the lowest point at age of 65-74, and then increased again. Thirty-nine percent of females and 63% of males treated their falls in clinics, instead of emergency departments.

Conclusion: Gender disparity of medically consulted falls and related injuries exits among adults. Age and gender targeted fall injury prevention interventions need further development. Significant numbers of fall-related injuries were treated at clinics; future research is needed to determine whether fall injury surveillance should be expanded to include outpatient clinics.
