OBJECTIVES: Acute appendicitis is common in the pediatric population and is difficult to diagnose in adolescent females. The validated Pediatric Appendicitis Score (PAS) has unclear utility in female adolescents. The purpose of this study is to determine the sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of the PAS for female adolescents compared to all other patients. METHODS: This study examined a retrospective observational cohort of patients ages 3 to 21 years in a pediatric emergency department with prospectively assigned PAS from an existing database. We compared the sensitivity, specificity, PPV, and NPV of the PAS for acute appendicitis among female adolescent patients (13 to 21 years) and all other patients. RESULTS: Of the 1,228 patients enrolled, 901 (73.4%) had a complete PAS. Among the 901 patients, 249 (27.6%) had pathology-proven appendicitis, 494 (54.8%) were female, and 272 (30.2%) were adolescent females. At a cutoff of ≥8, the PAS showed a specificity of 89% for adolescent females and 78% for all other patients (p < 0.001), although the specificities did not differ at a cutoff of ≥7. At both cutoffs, the PPVs were poor in both groups. At a cutoff of ≥3, the PAS showed similar sensitivities in both groups. At a cutoff of <3, the NPVs did not significantly differ between groups. CONCLUSION: At a cutoff of ≥8 (although not ≥7), the PAS demonstrated a higher specificity among female adolescents compared to all other patients. The PPV for both cutoffs in both groups were poor. At a cutoff of ≥3, sensitivities were equivalent. The NPV for a cutoff of <3 was acceptable but similar in both groups. While sensitivities were similar to previously reported, specificities in both groups were lower. This highlights the need for further investigation of the PAS's performance in specific subpopulations.
