Purpose: This study examined the risk factors of a delayed diagnosis of acute appendicitis in children undergoing an appendectomy.
Methods: This retrospective study involved children aged below 18 years, who underwent an appendectomy. After dividing them into a delayed diagnosis group and nondelayed diagnosis group according to the time interval between the initial hospital visit and final diagnosis, the risk factors of delayed diagnosis were identified using logistic regression analysis.
Results: Among 712 patients, 105 patients (14.7%) were classified in the delayed diagnosis group; 92 patients (12.9%) were diagnosed using ultrasonography (US), and both US and computed tomography were performed in 38 patients (5.3%). More patients in the delayed diagnosis group underwent US (P=0.03). Spring season and prior local clinic visit were significantly associated with a delayed diagnosis. Fever and diarrhea were more common in the delayed diagnosis group (fever: odds ratio [OR], 1.37; 95% confidence interval [CI], 1.05?1.81; diarrhea: OR, 1.94; 95% CI, 1.08?3.46; P<0.05). These patients showed symptoms for a longer duration (OR, 2.59; 95% CI, 1.78?3.78; P<0.05), and the admission course (OR, 1.26; 95% CI, 1.11?1.44; P<0.05) and C-reactive protein (CRP) levels (OR, 1.47; 95% CI, 1.19?1.82; P<0.05) were associated with the delayed diagnosis.
Conclusion: To decrease the rate of delayed diagnoses of acute appendicitis, symptoms such as fever and diarrhea, seasonal variations, admission course, and CRP levels should be considered and children with a longer duration of symptoms should be closely monitored.
