Foreign body aspiration score (FOBAS)-a prospectively validated algorithm for the management and prediction of foreign body aspiration in children. Eur J Pediatr 2024; 183:815-825. [PMID: 38017338 DOI: 10.1007/s00431-023-05347-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 11/19/2023] [Accepted: 11/20/2023] [Indexed: 11/30/2023]
Abstract
Foreign body aspiration (FBA) is a common cause of pediatric morbidity, but a standardized protocol to guide decision-making about bronchoscopy is lacking. We aimed to validate a new Foreign body aspiration score (FOBAS) for the pediatric emergency department (ED). Patients aged 0-18 years referred to the ED for suspected FBA were prospectively enrolled. FOBAS was calculated according to clinical features of a choking episode, sudden cough, exposure to nuts, absence of fever and rhinitis, stridor, and unilateral auscultatory and radiological findings. FBA risk was evaluated based on the total score (low, 1-3; moderate, 4-6; high, 7-10). Low-risk children were discharged from the ED and followed clinically. Moderate-risk children were hospitalized and evaluated by a pediatric pulmonologist, and high-risk children were referred directly for therapeutic bronchoscopy. Among the 100 enrolled children (59% males; median age 20 [interquartile range 11-39] months), a foreign body was diagnosed in 1/49 (2%), 14/41 (34.1%), and 9/10 (90%) with low, moderate, and high FOBAS, respectively (P < .001). Logistic regression indicated a higher risk for FBA with higher scores. The odds ratio for each additional point was 2.75 (95% confidence interval 1.78-4.24), and FOBAS showed a high predictive value for FBA (area under the curve 0.89). FOBAS implementation significantly reduced the rate of negative bronchoscopies, from 67.4% annually during 2016-2019 to 50% in 2020 (P = .042). CONCLUSION FOBAS reliably predicts FBA in cases of suspected FBA and improves management and in-hospital decision-making. WHAT IS KNOWN • Foreign body aspiration is a major cause of pediatric morbidity and mortality. • Currently, there is no unified protocol for children referred to the emergency department for suspected FBA, therefore, a well-defined algorithm is needed to improve the decision-making process. WHAT IS NEW • The pediatric Foreign body aspiration score (FOBAS) is a new, prospectively validated clinical score that shows high sensitivity and specificity for the presence of FBA in children. • FOBAS reduces unnecessary admissions and invasive procedures and leads to better clinical outcomes.

Abstract
OBJECTIVES The aim of this study is to identify the most common and important features within the presenting history, clinical examination and chest radiograph that are associated with foreign body (FB) aspiration in the paediatric population, to support rationalised decision making in regards to proceeding with diagnostic bronchoscopy. METHODS A retrospective notes review was conducted of 70 patients over a 12-year period at our tertiary referral centre. Their presenting history, clinical and radiographic signs were documented and univariate logistic regression model used to calculate odds ratios. RESULTS The main features identified within our cohort with a positive FB finding at bronchoscopy were history of a cough (OR 5.1, p = 0.008) and radiographic evidence of hyperinflation or air trapping (OR 7.1, p = 0.016). Zero patients with a FB presented with only a positive history in the absence of other clinical or radiological signs. History of a witnessed choking episode neither increased or decreased the likelihood of as aspirated FB (OR 1, p = 0.967). CONCLUSIONS We have identified two principal features, as described above, which are associated with paediatric FB aspiration. Reliance on a positive clinical history alone, but specifically the history of a witnessed choking episode, did not support the presence of a FB and other associated signs need to be considered in deciding to proceed to bronchoscopy.

Abstract
BACKGROUND This article evaluates the effect of coronavirus disease 2019 (COVID-19) pandemic on clinical course and management of cases that underwent bronchoscopy for suspected foreign body aspiration (FBA) in children. METHODS The patients who underwent bronchoscopy with a presumptive diagnosis of FBA between July 2018 and December 2021 were evaluated for demographic features, clinical findings, management details, and outcomes. Patients were divided in two groups: before pandemic (group A) and during pandemic (group B). RESULTS In total 79 cases with a median age of 5 years (4-5) in group A (n = 47) and 3 years (2-3) in group B (n = 32) were included (p < 0.05). The witnessed aspiration was significantly higher in group B (90.6%) when compared to group A (53%) (p < 0.05). Admission time was less than 48 hours in 30 cases (64%) in group A and 23 cases (72%) in group B (p = 0.002). The intervention time was less than 24 hours in 30 cases (64%) in group A, 9 cases (28%) in group B (p = 0.002). Bronchoscopy was performed after COVID-19 polymerase chain reaction (PCR) testing in all cases in group B. The positive FBA rate was 38% (n = 18) in group A, and 59% (n = 19) in group B (p = 0.067). CONCLUSION During pandemics, bronchoscopy for FBA was performed in younger infants than before pandemic and witnessed aspiration was significantly more common in that period. The differences in age groups and symptoms may be explained by spending more time at home during pandemics. Waiting for the PCR test results causes delays in the intervention. However, this delay did not cause any respiratory distress.

Evaluation of Foreign body aspiration score (FOBAS) in children- A retrospective cohort study. Eur J Pediatr 2023; 182:4205-4212. [PMID: 37450025 DOI: 10.1007/s00431-023-05095-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 06/22/2023] [Accepted: 07/03/2023] [Indexed: 07/18/2023]
Abstract
Foreign Body Aspiration (FBA) is a common medical emergency among young children, but the evaluation and management of a suspected FBA case can vary across physicians and centers. We aimed to identify which clinical, laboratory, and radiological findings can predict FBA in children and to evaluate a clinical score to improve FBA prediction. This is a retrospective cohort study of patients aged 0-18 years admitted to Soroka University Medical Center between 2010 and 2020 with suspected FBA. All patients underwent flexible bronchoscopy and were divided into positive and negative FBA groups. A newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, was evaluated for its predictability. The study included 412 children (median age 21 months, 56.8% females), of whom 154 (37.4%) had FBA and 258 (62.6%) did not. Multivariate regression analysis showed exposure to nuts/seeds, unilateral wheezing or decreased breath sounds, stridor, and suggestive findings on chest X-ray were significant risk factors for FBA (OR [95%CI] -1.994[1.290-3.082], 1.487[1.206-1.832], 1.883 [1.011-3.509] and 2.386[1.917-2.970], respectively). However, a choking episode, acute cough, and absence of fever and rhinorrhea did not predict FBA. FOBAS showed an increased risk of FBA for each additional point of the score, with an odds ratio of 1.572 (95% CI-1.389-1.799). Conclusion: FOBAS is a good predictor for the presence of FBA in children. Once prospectively validated, FOBAS could aid in decision-making at the emergency department, enabling more standardized care, reducing unnecessary procedures, and leading to better clinical outcomes. What is Known: • The evaluation and management of a child with suspected foreign body aspiration (FBA) vary across physicians and centers, without a consensus regarding the indications and criteria for performing bronchoscopy. • Flexible bronchoscopy is the standard procedure for the diagnosis and sometimes treatment of FBA in children, but it may hold potential complications. What is New: • We propose a newly developed foreign body aspiration score (FOBAS), based on medical history, physical examination, and chest X-ray findings, for the prediction of FBA in children at the emergency department. • The FOBAS is a good predictor of FBA in children. The score enables more standardized care and may reduce unnecessary procedures.

Abstract
Chest X-ray (CXR) is an important tool in the assessment of children with suspected foreign body aspiration (FBA), although it can falsely be interpreted as normal in one-third of the cases. The aim of this study is to evaluate the positive predictive value of CXR in children hospitalized with suspected FBA, when interpreted by three disciplines: pediatric pulmonology, pediatric radiology, and pediatric residents. This is a retrospective study that included children aged 0-18 years, admitted with suspected FBA, between 2009 and 2020 in one tertiary center. All patients underwent CXR and a flexible/rigid bronchoscopy for the definitive diagnosis of FBA, up to 1 week apart. Two physicians from each discipline interpreted the CXR, independently. Intra-raters' and inter-raters' agreements were assessed. Sensitivity, specificity, and area under the curve (AUC) were calculated for each discipline. Four hundred seventy-three children were included in the study, 175 (37%) with FBA and 298 (63%) without FBA on flexible/rigid bronchoscopy. The most common radiological findings, as interpreted by a pediatric pulmonologist, were unilateral hyperinflation (47%), radiopaque FB (37.6%), lobar atelectasis (10.3%), unilateral hyperinflation with atelectasis (3.4%), and lobar consolidation (1.7%). Intra-raters' agreement ranged from 0.744 (p < 0.001) among pediatric pulmonologists to 0.326 (p < 0.001) among pediatric radiologists. AUC for predicting FBA based on a CXR was 0.81, 0.77, and 0.7 when interpreted by pediatric pulmonologists, pediatric residents, and radiologists, respectively (p < 0.001). CONCLUSIONS CXR has a high positive predictive value and independently predicts FBA in children; however, normal CXR should not rule out FBA. Predictability is variable among different disciplines. WHAT IS KNOWN • Chest X-ray is an important tool in the assessment of children with suspected foreign body aspiration (FBA). • Chest X-ray can be interpreted as normal in one-third of the cases. WHAT IS NEW • Chest X-ray independently predicts FBA in children, with a high positive predictive value. • The ability of chest x-ray to predict FBA in children differs between pediatric residents, pediatric radiologists, and pediatric pulmonologists.

Abstract
OBJECTIVES Foreign body aspiration (FBA) has a wide clinical spectrum, patients may be asymptomatic or present with cardiopulmonary arrest. Radiological imaging methods are used in addition to history and physical examination findings for certain diagnosis. Lung ultrasonography (LUS), whose usage area is increasing year by year, can be included in these. This study aimed to investigate ultrasonography findings in FBA and hypothesized that LUS may have a standard place in FBA diagnosis. METHODS Patients who administered to the pediatric emergency department between August 2019-August 2021, considered according to the clinical findings and physical examination possible FBA, and who undergone rigid bronchoscopy by pediatric surgery were included in the study. RESULTS Thirty-two patients were included in the study. According to the results of bronchoscopy, FBA was detected in 25 patients. The most common finding in radiography was hyperinflation on one side, while LUS findings were confluent-B lines in eight patients, barcode-sign in five patients, pleural line abnormalities in two patients, and pleural consolidation in two patients. CONCLUSION This study is the first study aiming to evaluate LUS findings in FBA to the best of our knowledge. The B-lines, barcode sign, pleural line abnormalities and consolidation are seen findings in LUS of the patients with FBA. Although it is far from replacing chest radiography in these patients, it is possible to say that it has an equivalent value with chest radiography.

Abstract
To assess the different types of management of pediatric foreign body aspirations in order to help define guidelines, depending on clinical presentation. A national survey in France was emailed to all 30 university-affiliated departments of otolaryngology-head and neck surgery and pediatric pulmonologists in France. Data concerning the center and the experience of each participant were collected in order to define an "senior expert" group with experience of extracting more than 10 foreign bodies and a "junior/non-expert" group. Both groups answered questions concerning five clinical cases of foreign body aspiration of different severities. Ninety-eight participants answered this survey (75 otolaryngologists and 23 pulmonologists), representing 28 of the 30 university-affiliated departments in France with a completion rate of 89%. Responses of the senior expert group were similar for clear-cut situations, such as an asymptomatic child with a low probability of foreign body aspiration and for a symptomatic child with respiratory distress. However, for intermediate situations, management varied significantly according to the physician when considering clinical, radiological, and surgical management. In comparison to the senior expert group, the junior non-expert group seemed more precautious in the management of foreign body aspiration for intermediate cases, in particular, concerning the time at which extraction was performed. Conclusion: The management of foreign body aspiration depends on the physician's experience and the center's habits. In order to optimize patient care for foreign body aspiration, we suggested a management algorithm based on the senior expert group responses. What is Known: • Foreign body aspirations (FBA) are dreaded by pediatricians, pediatric otolaryngologists, and pulmonologists particularly because of the potential fatal outcome. • However, consensus concerning their management is not clearly defined in the literature. What is New: • This study is the first to evaluate the management of foreign body aspirations (FBA) from the clinical assessment by the emergency medicine physician to the extraction of the foreign body. • A management algorithm was designed and secondarily validated by the SE group to help to emergency medicine physician and specialist to manage FBA.

Abstract
BACKGROUND Airway foreign body can be a life-threatening issue in pediatric and adult patients, and the majority of these patients will first present to the emergency department. OBJECTIVE This article provides a narrative review of the diagnosis and management of airway foreign bodies for the emergency clinician. DISCUSSION Foreign bodies in the upper and lower airways are potentially life threatening. This affects all age groups but is more common in pediatric patients. A history of a witnessed ingestion or aspiration event should raise the clinical suspicion for an aspirated foreign body. Patients with upper-airway foreign bodies are more likely to present in respiratory distress when compared with lower-airway foreign bodies, which often present with more subtle signs. Stridor, drooling, and wheezing suggest respiratory distress, but the presenting clinical picture is often unclear and may only include a cough. Immediate intervention is required in the patient with hemodynamic instability or respiratory distress. Airway management including laryngoscopy, fiberoptic bronchoscopy, and cricothyrotomy may be needed in these patients, with the emphasis on removing the obstructing foreign body and securing the airway. Specialist consultation can assist in retrieving the foreign body and managing the airway. If the patient is stable, imaging and specialist consultation for potential operating room intervention should be considered. CONCLUSIONS An understanding of the presentation, evaluation, and management of the patient with an airway foreign body is essential for emergency clinicians.

Abstract
INTRODUCTION A simple algorithm for bronchoscopy was prepared in very young children. METHODS The patients aged 0-5 years who were applied with bronchoscopy because of suspected foreign body aspiration (FBA) analysed. RESULTS Evaluations were made of 89 patients, as 55 (61.7%) in the FBA (+) group and 34 (38.3%) in the FBA (-) group. FBA was determined most in the 1-2 years age group (28 patients, 50.9%, p = 0.04) due to organic hard foodstuffs (94.5%, p < 0.001). The parameters found to be significant were witnessing the event (OR 12.133, 95% CI 3.147-46.774, p < 0.001) and not obtaining unilateral respiratory sounds (OR 7.556, 95% CI 2.681-21.292, p < 0.001). The most significant diagnostic finding was the determination of unilateral hyperventilation on X-ray (OR 16.730, 95% CI 4.541-61.632, p < 0.001). The operating time and length of stay in hospital was significantly shorter in the FBA (-) patients (p < 0.001). CONCLUSION The presence of a witness, not obtaining unilateral respiratory sounds, and unilateral hyperventilation seen on X-ray are indications for bronchoscopy. In FBA (-) patients applied with bronchoscopy, the complication rate associated with the procedure is low, and the operating time and length of stay in hospital are short.

Development and Validation of a Scoring System for Assessment of Clinical Failure after Pediatric Robot-Assisted Laparoscopic Extravesical Ureteral Reimplantation: A Multi-Center Study. J Clin Med 2022; 11:jcm11051327. [PMID: 35268417 PMCID: PMC8910908 DOI: 10.3390/jcm11051327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 02/17/2022] [Accepted: 02/25/2022] [Indexed: 02/04/2023] Open
Abstract
We aimed to develop and validate a scoring system as an objective assessment tool for predicting clinical failure after pediatric robotic extravesical ureteral reimplantation. Data for this multi-institutional retrospective cohort was obtained from two tertiary referral hospitals. We defined clinical failure as incomplete radiographic resolution or post-operative febrile UTI. Patients were stratified into low, intermediate, and high-risk groups according to the score. External validation was performed using the model projected to the external validation cohort. An amount of 115 renal units in the development cohort and 46 renal units in the validation cohort were analyzed. The prediction score was calculated with weighted points to each variable according to their regression coefficient as age (year) + BMI + BBD times 10 + VUR grade times 7 + console time (h) + hospital stay times 6. The C-index of our scoring system was 0.850 and 0.770 in the development and validation cohorts, respectively. Clinical failure was significantly different among risk groups: 0% (low-risk), 3.3% (intermediate-risk), and 22.2% (high-risk) (p = 0.004) in the development cohort. A novel scoring system using multiple pre- and intra-operative variables provides a prediction of children at risk of failure after robotic extravesical ureteral reimplantation.

Foreign Body Aspiration in Children-Diagnostic Clues through a Clinical Case. Pediatr Rep 2022; 14:81-85.

Abstract
Foreign body aspiration is common in the pediatric age group, especially in males. Despite the high frequency of this potentially life-threatening event, it is not always easy to recognize it given the high variability of the clinical presentation and the potential of "pauci-symptomatic" inhalation. Moreover, a variable latency of the onset of symptoms since the moment of aspiration may be possible determining difficulties in the identification of the inhalation on an anamnestic basis. We describe the case of a 19-month-old boy who accessed the emergency room initially for a head trauma. The clinical evaluation, however, revealed an unexplained serious respiratory distress needing tracheal intubation. After our evaluation, we hypothesized that the severe respiratory distress determined an altered state of consciousness with following head trauma. The radiological findings raised the suspicion of foreign body aspiration for the presence of an atelectasis of the entire left lung. The computed tomography showed an abrupt interruption of the main bronchus at 12 mm from the hull. The following bronchoscopy identified an almond of 2 cm. We will review the literature to underline the diagnostic issues behind foreign body aspiration in children by highlighting the diagnostic clues that are helpful for emergency clinicians in the management of this condition.

Abstract
Chronic cough is a common symptom of many underlying respiratory and non-respiratory disorders and may be associated with less serious causes, such as gastroesophageal reflux and nasal diseases. Chronic cough in children differs from that in adults with respect to its etiologies and management since it can indicate a symptom of an underlying disease in children. Guidelines for managing chronic cough in children are based on recording the history, followed by physical examination, chest radiography, and spirometry. Thus, taking accurate respiratory history for coughing helps delineate the pathophysiological basis of the cause of chronic cough. Detailed history taking enhances the evaluation and treatment, and facilitates a tailored diagnostic identification of likely diagnoses. While studies have described evidence-based red flags in children with chronic cough, the value of skilled physicians regarding history taking has received less attention for the best patient care. In the present article, we outline the major questions comprising a detailed history taking for chronic cough in children.

Front Pediatr 2021; 9:694211. [PMID: 34722414 PMCID: PMC8555661 DOI: 10.3389/fped.2021.694211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 09/20/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Foreign body aspiration (FBA) in children is a common emergency that can easily be missed, leading to delays in treatment. Few large cohort studies have focused on errors in diagnostic assessment. The main purpose of this study was to analyze factors contributing to the initial misdiagnosis of FBA in children. Methods: We retrospectively reviewed the charts of 226 children diagnosed with FBA at the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University from January 2018 to November 2020. Cases were divided into two groups according to whether or not patients were initially misdiagnosed. The clinical characteristics of the two groups were then compared. The Diagnosis Error Evaluation and Research (DEER) taxonomy tool was applied to cases with initial misdiagnosis. Results: Of the 226 included children with a final diagnosis of FBA, 153 (67.7%) were boys. Ninety percent of patients were under 3 years old. More than half (61.9%) of the children were referred from primary institutions, and 38.1% visited tertiary hospitals directly. A total of 80 (35.4%) patients were initially misdiagnosed. More than half of misdiagnosed children received an alternative diagnosis of bronchiolitis (51.3%), the most common alternative diagnosis. Test failures (i.e., errors in test ordering, test performance, and clinician processing) were primarily responsible for the majority of initial diagnostic errors (76.3%), followed by failure or delay in eliciting critical case history information (20.0%). Characteristics significantly associated with initial misdiagnosis were: presentation over 24 h (OR 9.2, 95% CI 4.8-17.5), being referred from primary institutions (OR 8.8, 4.1-19.0), no witnessed aspiration crisis (OR 7.8, 3.0-20.3), (4) atypical signs or symptoms (OR 3.2, 1.8-5.7), foreign body not visible on CT (OR 36.2, 2.1-636.8), foreign body located in secondary bronchi (OR 4.8, 1.3-17.2), organic foreign body (OR 6.2, 1.4-27.2), and history of recurrent respiratory infections (OR 2.7, 1.4-5.3). Children with misdiagnosis tended to have a longer time from symptom onset to the definitive diagnosis of FBA (P < 0.001). Conclusions: More than one-third of children with FBA were missed at first presentation. Errors in diagnostic testing and history taking were the main reasons leading to initial misdiagnosis.

A new scoring system and clinical algorithm for the management of suspected foreign body aspiration in children: a retrospective cohort study. Ital J Pediatr 2021; 47:194. [PMID: 34583774 PMCID: PMC8480080 DOI: 10.1186/s13052-021-01147-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 09/04/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Cases of foreign body aspiration in children may be encountered in emergency departments. A suggestive history is important in diagnosing aspirated foreign body owing to the difficulty in making a diagnosis on the basis of an abnormal physical examination or chest radiography alone. The aim of this study was to examine the sensitivity and specificity of the presenting symptoms, physical examination, and radiologic findings as predictors of foreign body aspiration in children. In addition, a feasible simple algorithm with a scoring system was generated to indicate bronchoscopic investigation. METHODS In a retrospective cohort, medical records of patients aged less than 16 years with suspected foreign body aspiration who underwent flexible or rigid bronchoscopy were included. Data including age, sex, symptoms, physical examination findings, radiological features, nature and location of the foreign body, and outcome of the bronchoscopy were collected, and multivariable binary logistic regression analysis was employed for prediction of foreign body aspiration. RESULTS A total of 203 children were included, and the model showed excellent discrimination power for positive foreign body aspiration (area under the curve = 0.911) with an accuracy, sensitivity, and specificity of 86.2, 90.6, and 76.6%, respectively. The total weighted risk score at a cut-off > 2 showed a significant good power of discrimination (area under the curve = 0.879), with a sensitivity of 79.9% and specificity of 84.4%. Accordingly, a clinical algorithm was recommended. CONCLUSIONS The proposed scoring system and clinical algorithm might help in decision making with regard to the need and type of bronchoscopy in children presenting with potential foreign body aspiration. However, further prospective multicenter studies should be conducted to validate this scoring system.

Abstract
Purpose Foreign body aspiration (FBA) is a frequent cause of childhood morbidity and mortality. Diagnosis of FBA is challenging in the absence of a witnessed aspiration event. The aim of this study was to determine the accuracy of presenting symptoms as well as physical and radiologic findings as predictors of FBA in children. Thus, indications for bronchoscopy could be determined in such cases. Methods This retrospective cohort study was conducted in the ENT department, Kafr-elsheikh University Hospital. The medical records of patients younger than 16 years old who underwent rigid bronchoscopy for suspected FBA were included. Data including age, gender, symptoms, physical examination findings, radiological features, nature and location of foreign body, and outcome of the bronchoscopy were collected. Results This study included 130 patients, 105 (80.8%) patients were positive for the presence of a foreign body in their airways. Foreign bodies were most frequently (43.8%) lodged in the right main bronchus, and nuts (66.7%), were the most commonly retrieved. Multivariate regression analysis identified the presence of suggestive signs or symptoms as independent predictors of FBA on rigid bronchoscopy. Conclusion Objective finding of clinical signs eg unilateral wheezes on chest examination in the presence of symptoms such as a sudden cough, dyspnea, and hoarseness could predict FBA and help physicians in deciding bronchoscopy.

Abstract
Importance Although various clinical prediction models (CPMs) have been described for diagnosing pediatric foreign body aspiration (FBA), to our knowledge, there is still no consensus regarding indications for bronchoscopy, the criterion standard for identifying airway foreign bodies. Objective To evaluate currently available CPMs for diagnosing FBA in children. Data Sources Performed in Ovid MEDLINE, Ovid Embase, PubMed, Web of Science, and CINAHL database with citation searching of retrieved studies. Study Selection Prediction model derivation and validation studies for diagnosing FBA in children were included. Exclusion criteria included adult studies; studies that included variables that were not available in routine clinical practice and outcomes for FBA were not separate or extractable. Data Extraction and Synthesis We followed the Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies and the Prediction Model Risk of Bias Assessment Tool framework. Data were pooled using a random-effects model. Main Outcomes and Measures The primary outcome was the diagnosis of FBA as confirmed by bronchoscopy. Characteristics of CPMs and individual predictors were evaluated. The final model presentation with available measures of performance was provided by narrative synthesis. A meta-analysis of individual predictor variables and prediction models was performed. Results After screening 4233 articles, 7 studies (0.2%; 1577 patients) were included in the final analysis. There were 6 model derivation studies and 1 validation study. Air trapping (odds ratio [OR], 8.3; 95% CI, 4.4-15.5), unilateral reduced air entry (OR, 4.8; 95% CI, 3.5-6.5), witnessed choking (OR, 3.1; 95% CI, 1.0-9.6), wheezing (OR, 2.5; 95% CI, 1.2-5.2), and suspicious findings suggestive of FBA on radiography (OR, 18.5; 95% CI, 5.0-67.7) were the most commonly used predictor variables. Model performance varied, with discrimination scores (C statistic) ranging from 0.74 to 0.88. The pooled weighted C statistic score of all models was 0.86 (95% CI, 0.80-0.92). All studies were deemed to be at high risk of bias, with overfitting of models and lack of validation as the most pertinent concerns. Conclusions and Relevance This systematic review and meta-analysis suggests that existing CPMs for FBA in children are at a high risk of bias and have not been adequately validated. No current models can be recommended to guide clinical decision-making. Future CPM studies that adhere to recognized standards for development and validation are required.
