BackgroundDistal radius fractures are among the most common orthopaedic injuries and are managed both surgically and non-surgically. To date, no study has examined the role hospital teaching status plays in the rates of surgical intervention. MethodsThe Nationwide Inpatient Sample (NIS) was queried for years 2003–2014. Patients with a distal radius fracture were identified using International Classification for Disease, Ninth Revision (ICD-9) disease codes. Surgical intervention was determined using ICD-9 procedure codes. Exclusion criteria were patients younger than age 18, polytrauma, open fractures, records with missing data, and records where the primary procedure was something other than open reduction of a radius or ulna fracture, closed reduction of a radius or ulna fracture, or blank. Chi-squared tests were run for demographic and socioeconomic data to identify significant variables. Significant variables were then included alongside hospital teaching status in a binomial logistic regression model. Significance was defined as P < 0.05. ResultsA weighted total of 98,831 patients were included in the study. Of those, 45,234 (45.8 %) were treated at teaching hospitals. Patients in teaching hospitals were more likely to be younger, male, non-white, and non-Medicare insured than non-teaching hospitals. Injuries were treated surgically in 64.6 % of total cases. Surgical intervention was more common in teaching hospitals than non-teaching hospitals (69.1 % vs. 60.8 %, P < 0.01). After controlling for demographic and socioeconomic factors, patients at teaching hospitals were 31 % more likely to undergo surgical treatment than those at non-teaching hospitals. Other factors that were independently predictive of surgical treatment were age, race, and insurance type. ConclusionIn the setting of distal radius fractures, teaching hospitals have higher rates of surgical intervention than non-teaching hospitals. These results suggest that the involvement of medical trainees may play a role in the surgical decision-making process.
