Predictive value of clinico-radiological variables in the management of suspected foreign body aspiration in children: A ten-year retrospective cohort study
Abstract
Background Definite history is not always present in children with foreign body aspiration (FBA), hence necessitating a high index of suspicion. Objective To assess the predictive value of clinico-radiological variables among children presenting with features of suspected FBA and to document their course in a tertiary care teaching hospital. Materials and Methods In this retrospective observational study, we included children aged below 15 years presenting with clinical features of suspected FBA. Data was obtained from case records. Multivariable binary logistic regression analysis (MVA) was performed to determine statistically significant predictors of FBA, and Weighted Risk Scores (WRS) were calculated to determine the significance of the model. Results Of the 296 children included in the study and having undergone bronchoscopy, 84.5% were toddlers; 269 (90.87%) had a foreign body (FB) removed. Organic material was commonly found with 64.3% being peanut and right main bronchus, the commonest lodging site (50.6%). Of the 54 (18%) children with symptomatic but unwitnessed FBA, 45 (83.3%) had a FB retrieved. Choking with sudden onset cough, stridor, unilateral decreased breath sounds, abnormal chest radiograph, unilateral hyperinflation and mediastinal shift correlated with FBA (P 2 showed good power of discrimination with sensitivity, specificity and AUC of 60.2%, 77.8% and 0.704%, respectively. Conclusions The proposed predictive value-based scoring system enhances accuracy in decision-making regarding bronchoscopy in children with suspected FBA.
