BackgroundThe purpose of this study was to identify the incidence of upper extremity injuries presenting to emergency departments (EDs) nationally.MethodsThe Nationwide Emergency Department Sample (NEDS) database was queried using International Classification of Diseases, Ninth Revision (ICD-9) codes specific for hand/wrist injuries to identify national estimates of ED visits. The incidence, mean age, gender, payer mix, hospital type, location (metropolitan vs nonmetropolitan), and geographic region were recorded.ResultsIn total, 2 791 257 patients with upper extremity injuries and infections were treated at an ED in 2010. In total, 7.4% resulted in hospital admission; 57% of patients were male. Most common age group affected was 18 to 44 years (44%), followed by those less than 17 years (24%) and 45 to 64 years (21%). The 3 most common injury classifications were soft tissue contusions (37%), fractures (27%), and infections (17%). Thirty-seven percent of patients had private insurance, 21% had Medicaid, 19% were uninsured, 13% Medicare, and 10% other. In total, 63% of visits were seen in nonteaching EDs, 80% were seen in metropolitan cities, and 65% of visits were seen at non-trauma-designated hospitals. Geographically, 37% of visits were in the South, 25% Midwest, 20% Northeast, and 18% in the West.ConclusionsSoft tissue contusion was the most frequent diagnosis. More than half of the patients were male, while the majority of patients were under the age of 44. Ninety-three percent of patients did not require hospital admission. Half had private insurance and the two-thirds of these patients were seen at nonteaching facilities.
