Abstract

Purpose: To estimate the rate of surgical treatment of paediatric proximal humerus fractures over time utilizing a large, publicly available national database.

Methods: The Healthcare Cost and Utilization Project Kids' Inpatient Database was evaluated between the years 2000 and 2012. Proximal humerus fractures were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9 CM) diagnosis codes. ICD-9 CM procedure codes were used to identify patients who received surgical treatment. Univariable and multivariable logistic regression were used to determine variables associated with greater proportions of surgical treatment. All statistical analyses were performed utilizing SAS statistical software v.9.4. Statistical significance was set at p < 0.05.

Results: A total of 7520 proximal humerus fracture admissions were identified; 3247 (43.2%) were treated surgically. The percentage of patients receiving surgery increased from 39.3% in 2000 to 46.4% in 2012 (p < 0.001). After adjustment for potential confounders, increased age, increased ICD-9 derived injury severity scores (ICISS) and more recent year were associated with an increased proportion of patients receiving surgical treatment (p < 0.001). Medicaid payer status (p < 0.001) and admission to a children's hospital (p = 0.045) were associated with a lower proportion of surgical treatment.

Conclusion: The rate of operative treatment of paediatric proximal humerus fractures increased over time between 2000 and 2012. Increased surgical rates were independently associated with older age, increased ICISS, treatment at a non-children's hospital and non-Medicaid insurance status. Further study is needed to provide evidence to support improved outcomes after operative treatment of paediatric proximal humerus fractures.
