36Background: To identify 1) factors that are associated with a near miss or safety incident (NMSI) in patients undergoing radiation therapy; 2) the most common root causes of NMSIs and their relationship with incident severity. Methods: We retrospectively studied NMSIs filed between October 2014 and April 2016. We extracted patient-, treatment-, and disease-specific data from patients with a NMSI (n=200; incident group) and a similar group of control patients (n=200) matched in time, without a NMSI. A root cause was determined for each incident. A univariate analysis was performed to determine which patient-, disease-, and treatment-specific factors were different between the incident and control groups. Next, multivariate logistic regression was used to determine the significant factors contributing to NMSIs. Multivariate logistic regression was used to determine the most common root causes of NMSIs and their relationship with incident severity. A p value of 0.05 was used to test the statistical signifi...
