Abstract
PURPOSE: To propose a new scoring system to predict foreign body aspiration (FBA) in children. METHODS: Children who underwent bronchoscopy for FBA were evaluated for age, sex, history of aspiration, physical examination, radiological findings and results of bronchoscopy retrospectively. A new proposed FBA scoring including statements about history, physical and radiological findings were applied to all patients to define a total score. The results of each statement and total FBA score were compared according to bronchoscopy findings. The sensitivity and specificity of FBA score and cut-off values of total FBA score to predict positive cases were evaluated. RESULTS: Totally 720 patients with a male to female ratio of 227:133 were included. FBA was noted in 52.1% (n=375) of cases. When the scoring system compared with the existence of foreign body (FB), the patient history had no statistical significance to predict positive cases (p>0.05). The existence of FB was significantly associated with physical examination, radiological findings and total FBA score (p<0.001). The revised scoring system without history parameters had range of total scores 0 to 5. The total scores were obtained by sum of physical findings and radiological parameters and the cut-off value of 2 had the highest diagnostic performance with sensitivity and specificity of 77.9% and 74.8% to predict FBA in children. CONCLUSION: Our results suggest that the proposed scoring system can be utilized to predict FBA in children. The total score higher than 2 is predictive for FBA. Although, physical and radiologic findings are strong parameters for positive bronchoscopy, the history of FBA has no diagnostic utility. LEVEL OF EVIDENCE: Level III (retrospective comparative study) STUDY TYPE: Diagnostic study.
