BackgroundStudies have assessed the type of diagnostic imaging used in the treatment of appendicitis in children. Few studies investigated racial/ethnic and insurance disparities in imaging modalities used in pediatric patients diagnosed with appendicitis. Our study seeks to determine whether race/ethnicity and insurance status are associated with imaging modality chosen for pediatric patients diagnosed with appendicitis in the emergency department.MethodsThis was a retrospective cohort study utilizing data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2019. We included children <18 years old with a ICD-9-CM and ICD-10-CM diagnosis of appendicitis. Exposures were patient race/ethnicity and insurance status. Outcome of interest was imaging modality. We conducted adjusted survey logistic regression to evaluate the patient characteristics and receipt each of the imaging modalities among those with a diagnosis of appendicitis.ResultsOf 308,140,115 emergency department (ED) visits, 1,126,865 (0.37%) had a diagnosis of appendicitis. Overall, male patients were more likely to receive CAT scan in comparison to female children (OR=2.52, 95% CI= 1.16-5.49). Additionally, Hispanic children who had significantly greater odds of obtaining ultrasound (OR= 4.56, 95% CI=1.09-19.12). Hispanic children were also less likely to receive x-ray (OR= 0.31, 95% CI=0.11-0.89) or computed tomography (CT) scans (OR= 0.23, 95% CI=0.07-0.76). Children diagnosed with appendicitis who had insurance other than private, Medicare, Medicaid, or self-pay were significantly more likely to receive x-ray studies (OR=4.39, 95% CI= 1.23-15.69).Conclusions And Global Health ImplicationsThis study demonstrated the presence of racial/ethnic and insurance status disparities in the imaging modality chosen to assist in diagnosing appendicitis in pediatric patients.Published by Elsevier Inc.
