PARC Score is the Most Promising Pediatric Appendicitis Risk Stratification Tool * Validation of Pediatric Appendicitis Risk Calculator (PARC) study in children 5-18 years old, <96 hours of abdominal pain with suspected appendicitis in pediatric EDs compared to Pediatric Appendicitis Score (PAS) found PARC to be more accurate at predicting appendicitis * 50% of patients were risk stratified into "low" or "very low" risk (safe for discharge with watchful waiting) or "high" risk (immediate surgical consult with option of no imaging) * Also validated in community ED setting in multicenter prospective observational study of >2000 patients * Items in the PARC score include: sex, age, fever, duration of pain, migration of pain to RLQ, maximum tenderness in RLQ, guarding, pain with cough/hop/walk, WBC, absolute neutrophil count * An online calculator is necessary to calculate this score * Limitations of the PARC score are that it has yet to be compared to physician gestalt, requires blood work which may not be necessary, still requires an implementation study, and about half the patients will still require further workup in the ED Expand to view reference list * Kharbanda AB, Vazquez-benitez G, Ballard DW, et al.
