IntroductionThe US-Mexico border is medically underserved. Recent political changes may render this population even more vulnerable. We hypothesized that children on the border present with high rates of perforated appendicitis due to socioeconomic barriers.MethodsA prospective survey was administered to children presenting with appendicitis in El Paso, Texas. Primary outcomes were rate of perforation and reason for diagnostic delay. We evaluated the association between demographics, potential barriers to care, risk of perforation and risk of misdiagnosis using logistic regression. p < 0.05 was considered significant.Results98 patients participated from October 2016 to February 2017. 96 patients (98%) were Hispanic and 81 (82%) had Medicaid or were uninsured. 11 patients (11%) resided in Mexico or Guatemala. Patients were less likely to receive a CT and more likely to receive an ultrasound if they presented to a freestanding children's hospital (p = 0.01). 37 patients (38%) presented with perforation, of which 19 (52%) were the result of practitioner misdiagnosis. Patients who presented to a freestanding children's hospital were less likely to be misdiagnosed than patients presenting to other facilities (p = 0.05). Children who underwent surgery in a freestanding children's hospital had the shortest length of stay after adjusting for perforation status and potential confounders (p < 0.01).ConclusionChildren with low socioeconomic status did not have difficulty accessing care on the USA-Mexico border, but they were commonly misdiagnosed. Children were less likely to receive a CT, more likely to be correctly diagnosed and length of stay was shorter when patients presented to a freestanding children's hospital.
