Pediatric Esophageal Foreign Bodies: The Role of Socioeconomic Status in Ingestion Patterns.

OBJECTIVE: Pediatric esophageal foreign bodies (EFBs) are common and can result in serious complications. Little is known about the influence of socioeconomic status (SES) on EFB ingestion in children. The goal was to study SES as a risk factor for dangerous foreign body ingestion and in-hospital complications in children. METHODS: This was a retrospective cohort study of children presenting to a tertiary care pediatric hospital with an esophageal foreign body from 2010 to 2021. SES was assessed for each patient by linking their postal code to the Ontario Marginalization Index to determine a quintile score across four dimensions of deprivation: residential instability, material deprivation, dependency, and ethnic concentration. Dangerous EFBs were defined as magnets, batteries, sharp objects, or bones. In-hospital complications included: intensive care unit admission, prolonged length of stay, and postoperative sequelae. RESULTS: A total of 680 patients were included. Dangerous EFB ingestion was higher for children with increased residential instability (odds ratio [OR], 2.1; 95% confidence interval [CI], 1.2-3.6) and increased material deprivation (OR, 2.2; CI, 1.9-2.8), which was similarly true for odds of complications. Odds of dangerous EFB ingestion were higher in older children (OR, 1.1; CI, 1.0-1.1) and odds of complications were higher in children with comorbidities (OR, 1.1; CI, 1.0-1.3). CONCLUSION: Higher levels of housing instability and material deprivation are associated with dangerous EFB ingestion and complications related to EFB ingestion. These findings emphasize the role that SES plays on child health outcomes and the need for initiatives to mitigate these disparities. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:2945-2953, 2024.

The global, regional, and national burden of foreign bodies from 1990 to 2019: a systematic analysis of the global burden of disease study 2019.

BACKGROUND: Foreign bodies (FBs) are a common emergency in medical institutions, that can occur in any area and among people of any age, which are common public health problems. Understanding the epidemiological characteristics of FBs is crucial for their prevention and control. The purpose of this study was to analyze the epidemiological characteristics of FBs worldwide through the data from the Global Burden of Disease Study 2019 (GBD 2019). METHODS: We obtained data from the GBD 2019, which is an important public database to understand the disease burden of FBs. Joinpoint was used to analyze temporal trends in the incidence and death trends of FBs, which is widely used to study the long-term temporal trend of the burden of diseases. SaTScan was used to detect spatial-temporal clusters of pulmonary aspiration and foreign body in the airway (PAFBA), which is based on a Poisson model, scanning the number of people and diseases in the study area to obtain the spatial-temporal clusters of diseases. RESULTS: Globally, the age-standardized incidence rate (ASIR) and the age-standardized death rate (ASDR) of FBs in 2019 were 869.23/100,000 (679.92/100,000-1120.69/100,000) and 1.55/100,000 (1.41/100,000-1.67/100,000), respectively. The ASIR and ASDR showed downtrends with average annual percent changes (AAPCs) of -0.31% and - 1.47% from 1990 to 2019. Of note, the ASIR showed an uptrend during 2010-2019, especially in high, high-middle, and middle SDI regions. Stratified analysis by age group showed that ASIR increased in each age group in recent years. From 1990 to 2019, the ASDR in the over-70 age group showed an uptrend worldwide, especially in high and high-middle SDI regions. In different types of FBs, the ASDR of PAFBA was the highest. The death burden of PAFBA was mainly clustered in 82 countries during 1993-2007, such as Canada, Cuba, and Mexico. CONCLUSION: The most important goal is to improve public awareness and emergency knowledge of FBs through publicity methods, such as the internet or offline activities, and to improve laws and regulations. Additionally, different age groups need different targeted measures, such as strengthening the care of children, caring for elderly individuals, improving necessary monitoring programs and reporting systems, conducting effective hazard assessments, and publicity and education activities.

Patient characteristics, outcomes and hospital-level healthcare costs of foreign body ingestion from an Australian, non-prison referral centre.

OBJECTIVE: Foreign body ingestion (FBI) occurs infrequently but can be associated with rare risks including perforation. There is limited understanding of the impact of adult FBI in Australia. We aim to evaluate patient characteristics, outcomes and hospital costs of FBI. DESIGN: A retrospective cohort study of patients with FBI was performed at a non-prison referral centre in Melbourne, Australia. International Classification of Disease-10 coding identified patients with gastrointestinal FBI over financial years 2018-2021. Exclusion criteria were food bolus, medication foreign body, object in anus or rectum, or non-ingestion. Criteria for 'emergent' classification were oesophagus, size >6 cm, disc batteries, airway compromise, peritonitis, sepsis and/or suspected viscus perforation. RESULTS: Thirty-two admissions attributed to 26 patients were included. The median age was 36 years (IQR: 27-56), 58% were male and 35% had a prior psychiatric or autism spectrum disorder. There were no deaths, perforations or surgery. Gastroscopy was performed in 16 admissions and 1 was scheduled following discharge. Rat-tooth forceps were used in 31% and an overtube was used in 3 cases. The median time from presentation to gastroscopy was 673 minutes (IQR: 380-1013). Management was adherent to European Society of Gastrointestinal Endoscopy guidelines in 81%. After excluding admissions with FBI as a secondary diagnosis, median admission cost was $A1989 (IQR: $A643-$A4976) and total admission costs over the 3 years was $A84 448. CONCLUSION: FBI in an Australian, non-prison referral centre is infrequent, can often be safely managed expectantly, and has limited impact on healthcare utilisation. Early, outpatient endoscopy could be considered for non-urgent cases, which may reduce costs while maintaining safety.

Risk Reduction Strategy to Decrease Incidence of Retained Surgical Items.

BACKGROUND: Retained surgical items (RSIs) are rare but serious events associated with significant morbidity and costs. We assessed the effectiveness of radiofrequency (RF) detection technology and Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) in reducing the incidence of RSIs. STUDY DESIGN: All RSIs reported to the New York Patient Occurrence Reporting and Tracking System at five large urban teaching hospitals from 2007 to 2017 were analyzed. In 2012, TeamSTEPPS training was provided to all perioperative staff at each site, and use of RF detection became required in all procedures. The incidence of events before and after the interventions were compared using odds ratios. RESULTS: A total of 997,237 operative procedures were analyzed. After the interventions, the incidence of RSIs decreased from 11.66 to 5.80 events per 100,000 operations (odds ratio [OR] [95% CI] = 0.50 [0.32 to 0.78]). The frequency of RSIs involving RF-detectable items decreased from 5.21 to 1.35 events per 100,000 operations (OR [95% CI] = 0.26 [0.11 to 0.60]). The difference in RSIs involving non-RF-detectable surgical items was not statistically significant. CONCLUSIONS: The incidence of RSIs was significantly lower during the time period after implementing RF detection technology and after TeamSTEPPS training, primarily driven by a decrease in retained RF-detectable items. RF detection technology may be worth pursuing for hospitals looking to decrease RSI frequency. The benefit of TeamSTEPPS training alone may not result in a reduction of RSIs.

Rectal foreign body removal: increasing incidence and cost to the NHS.

INTRODUCTION: Insertion of foreign objects into the rectum is a well-described phenomenon and not an uncommon referral to the general surgeon on call. Although usually not life-threatening, there can be consequences following migration of the object or perforation of the large bowel. This study looks at the incidence of removal of foreign objects from the rectum over the last decade and the financial burden it presents to the NHS. METHODS: Hospital Episode Statistics for 2010-2019 were used to calculate the number of rectal foreign bodies that required removal in hospital. Data for age groups and genders have been compared. RESULTS: A total of 3,500 rectal foreign bodies were removed over the course of 9 years. Males accounted for 85.1% of rectal foreign bodies whilst 14.9% were females. This equates to 348 bed-days per annum. Admission peaks were observed in the second and fifth decades of life. CONCLUSION: This study shows that the incidence of rectal foreign bodies is higher in men and has been increasing over the period studied. Most foreign bodies can be removed trans-anally with the use of anaesthesia, with only a small proportion of patients requiring hospital stay over 24 hours (mean length of stay = 24 hours). Nearly 400 rectal foreign body removals are performed each year with an annual cost of £338,819, illustrating the effect this has on NHS resources.

Epidemiology of genitourinary foreign bodies in the united states emergency room setting and its association with mental health disorders.

The epidemiology of genitourinary foreign bodies (GUFB) has been mainly described through case reports and small series. The aim of this study is to investigate the epidemiologic, medical, and socioeconomic factors associated with GUFB, along with the resultant costs of care in emergency departments (EDs) nationwide. ED visits with the primary diagnosis of a GUFB between 2010 and 2014 were abstracted from the Nationwide Emergency Department Sample database. Between 2010 and 2014, a weighted estimate of 102,333 visits to the ED with GUFB were recorded in the US, representing a national incidence of 7.6 ED visits per 100,000 persons. Of these visits, 4.7% resulted in admission and males were more likely to be admitted (24.8% vs. 2.1%, p < 0.01). A third of patients had low income, 30% had no medical insurance, and a third of patients had Medicaid. Urethra/bladder and penile foreign bodies had a significant association with mental health disorders (35.6%). Vulvar/vaginal foreign bodies had a lower prevalence of mental health disorders (6.1%). Costs of managing patients in the ED averaged $3769. More importantly, penile or urethra/bladder foreign bodies incurred a higher cost ($30,071). This is the largest population-based study investigating the epidemiology of GUFB. GUFB are more common in young women and the majority of them are vulvar/vaginal. Urethral and bladder foreign bodies occurred in older male patients and are associated with longer hospital stays and costs. Over one third of male patients with urethra/bladder had significant mental health disorders.

The Effect of Radiofrequency Technology on Time Spent Searching for Surgical Sponges and Associated Costs.

Retained surgical items (eg, sponges, instruments) remain the most frequently reported sentinel events. The primary strategy for preventing retained sponges is the sponge count. Reconciling sponge counts is time consuming and can extend the duration of operative and other invasive procedures. The primary objective of this observational study was to evaluate the effect of a radiofrequency (RF) surgical-sponge detection system on time spent searching for surgical sponges. The study included 27,637 procedures during nine months before and after implementing an RF surgical-sponge detection system. After implementation of the system, time spent searching for sponges was reduced by 79.58%, the percentage of unreconciled counts was reduced by 71.28%, and time spent using radiography to rule out a retained sponge was reduced by 46.31%. This resulted in a reduction of costs. These findings should be used as part of a comprehensive cost analysis of alternative methods when evaluating RF sponge detection technology.

Button battery exposures in Australian children: a prospective observational study highlighting the role of poisons information centres.

CONTEXT: Button battery ingestion is a worldwide problem, with evidence of increasing harms and deaths in recent decades. Australian Poisons Information Centre (PIC) experience includes cases of treatment delay due to lack of healthcare professional recognition of risks, and/or lack of local resources. This study aims to characterise Australian button battery exposures, focusing on exposure circumstances, and preventable health system shortcomings. METHODS: A prospective observational study of button battery exposure calls to New South Wales PIC, November 2015-May 2017, using a follow-up survey to obtain outcome data and additional details. Survey data was combined with nationwide PIC data over the same period. RESULTS: Australian PICs were consulted on 578 exposures over the 19-month study period, including 506 paediatric cases. The median (IQR) age for the paediatric cases was 23 months (14-36 months). Where the source was identified, batteries came from toys in 26% of cases, with hearing aids, watches, and remote controls being other common sources. Children in outer regional, remote and very remote areas were overrepresented, and 15 cases were referred to a different hospital due to X-ray facilities being unavailable at their nearest hospital. We identified inconsistent triage from a range of first responders, and knowledge gaps regarding button battery dangers amongst some healthcare professionals. DISCUSSION: Button battery exposures are a common call to Australian PICs. This study highlights a potential role of education campaigns, professional guidelines, and child-resistant battery compartments in toys and household devices. PICs calling ahead to ensure X-ray availability/diversion to a different hospital likely reduced delays for this time-critical exposure. CONCLUSIONS: Button battery exposures continue to be a problem in Australia. Data collected by PICs can provide useful information for public health and product safety initiatives. A PIC-led protocol to direct initial medical management of button battery exposures could reduce delays and improve outcomes.

Patient Co-Morbidity and Functional Status Influence the Occurrence of Hospital Acquired Conditions More Strongly than Hospital Factors.

BACKGROUND: Never events (NE) and hospital-acquired conditions (HAC) are used by Medicare/Medicaid Services to define hospital performance measures that dictate payments/penalties. Pre-op patient comorbidity may significantly influence HAC development. METHODS: We studied 8,118,615 patients from the NIS database (2002-2012) who underwent upper/lower gastrointestinal and/or hepatopancreatobiliary procedures. Multivariate analysis, using logistic regression, was used to identify HAC and NE risk factors. RESULTS: A total of 63,762 (0.8%) HAC events and 1645 (0.02%) NE were reported. A total of 99.9% of NE were retained foreign body. Most frequent HAC were: pressure ulcer stage III/IV (36.7%), poor glycemic control (26.9%), vascular catheter-associated infection (20.3%), and catheter-associated urinary tract infection (13.7%). Factors correlating with HAC included: open surgical approach (AOR: 1.25, P < 0.01), high-risk patients with significant comorbidity [severe loss function pre-op (AOR: 6.65, P < 0.01), diabetes with complications (AOR: 2.40, P < 0.01), paraplegia (AOR: 3.14, P < 0.01), metastatic cancer (AOR: 1.30, P < 0.01), age > 70 (AOR: 1.09, P < 0.01)], hospital factors [small vs. large (AOR: 1.07, P < 0.01), non-teaching vs teaching (AOR: 1.10, P < 0.01), private profit vs. non-profit/governmental (AOR: 1.20, P < 0.01)], severe preoperative mortality risk (AOR: 3.48, P < 0.01), and non-elective admission (AOR: 1.38, P < 0.01). HAC were associated with increased: hospitalization length (21 vs 7 days, P < 0.01), hospital charges ($164,803 vs $54,858, P < 0.01), and mortality (8 vs 3%, AOR: 1.14, P < 0.01). CONCLUSION: HAC incidence was highest among patients with severe comorbid conditions. While small, non-teaching, and for-profit hospitals had increased HAC, the strongest HAC risks were non-modifiable patient factors (preoperative loss function, diabetes, paraplegia, advanced age, etc.). This data questions the validity of using HAC as hospital performance measures, since hospitals caring for these complex patients would be unduly penalized. CMS should consider patient comorbidity as a crucial factor influencing HAC development.

Hospital-acquired conditions after surgery for gynecologic cancer - An analysis of 82,304 patients.

OBJECTIVE: To evaluate the hospital-acquired condition (HAC) following oophorectomy and/or hysterectomy for gynecologic cancer patients based on clinical outcomes and costs. MATERIALS AND METHODS: Data were obtained from the Nationwide Inpatient Sample from 2005 to 2011. Chi-squared and Wilcoxon rank sum two-sample tests and multivariate logistic regression model were used for statistical analysis. RESULTS: Of 82,304 women (median age: 60 years, range: 1-101), 49,386 (60.0%) had endometrial, 23,510 (28.6%) had ovarian, and 9408 (11.4%) had cervical cancers. Of 135 HAC events, these involved catheter-associated urinary tract infections (n = 47), vascular catheter-associated infection (n = 41), foreign object retained after surgery (n = 19), pressure ulcers (n = 16), manifestation of poor glycemic control (n = 10), and air embolism (n = 2). Older patients (≥60 years) experienced more HACs relative to younger (0.23% vs. 0.09%; OR = 2.13, 95% CI: 1.30-3.50; p = 0.003), and patients with Medicaid experienced more HACs compared to those with private insurance (0.35% vs. 0.10%; OR = 3.09, 95% CI: 1.70-5.62; p < 0.001). Laparoscopic surgeries were associated with less HACs compared to open surgeries (0.05% vs. 0.19%; OR = 0.41, 95% CI: 0.19-0.90; p = 0.03). Length of hospitalization and hospital charges were greater for those with HACs, (12 days vs. 3 days; p < 0.001; $89,324 vs. $31,107; p < 0.001), respectively. CONCLUSION: The odds of hospital-acquired conditions were higher in older patients, open surgery, Medicaid insured with higher associated hospital charges.

A Socio-Technical Exploration for Reducing & Mitigating the Risk of Retained Foreign Objects.

A Retained Foreign Object (RFO) is a fairly infrequent but serious adverse event. An accurate rate of RFOs is difficult to establish due to underreporting but it has been estimated that incidences range between 1/1000 and 1/19,000 procedures. The cost of a RFO incident may be substantial and three-fold: (i) the cost to the patient of physical and/or psychological harm; (ii) the reputational cost to an institution and/or healthcare provider; and (iii) the financial cost to the taxpayer in the event of a legal claim. This Health Research Board-funded project aims to analyse and understand the problem of RFOs in surgical and maternity settings in Ireland and develop hospital-specific foreign object management processes and implementation roadmaps. This project will deploy an integrated evidence-based assessment methodology for social-technical modelling (Supply, Context, Organising, Process & Effects/ SCOPE Analysis Cube) and bow tie methodologies that focuses on managing the risks in effectively implementing and sustaining change. It comprises a multi-phase research approach that involves active and ongoing collaboration with clinical and other healthcare staff through each phase of the research. The specific objective of this paper is to present the methodological approach and outline the potential to produce generalisable results which could be applied to other health-related issues.

Geographic health disparities in the Los Angeles pediatric esophageal foreign body population.

OBJECTIVE: To assess geographical sociodemographic differences in the pediatric esophageal foreign body population of Los Angeles. METHODS: We retrospectively reviewed the medical records of 128 consecutive pediatric patients at Children's Hospital Los Angeles (CHLA) from 2014 to 2017 with a diagnosis of a retained foreign body in the esophagus removed by rigid or flexible esophagoscopy. Sociodemographic information including zip code of residence was extracted and analyzed with Chi-square, Fisher's exact test, and multivariable logistic regression. RESULTS: The average age of patients with a retained esophageal foreign body in this study was 2.5 years old, 52.3% were male, 91.4% had no past medical history, 53.1% were Hispanic, 82.0% had public health insurance, and 63.3% were transfers from an outside hospital. The most common foreign body removed was a coin. There were no significant differences in gender, race, type of health insurance, or income between patients that lived within 10 miles of CHLA versus farther than 10 miles. On multivariable analysis, zip codes with a high volume of esophageal foreign bodies were more likely to be lower income neighborhoods. Gender, race, type of health insurance, and distance from CHLA were not risk factors for zip codes with a high volume of esophageal foreign bodies. CONCLUSION: Geographic areas in the greater Los Angeles community with a high volume of retained esophageal foreign bodies requiring endoscopic removal at our institution are associated with lower income neighborhoods. Further studies should be performed to better understand health disparities within the U.S. pediatric esophageal foreign body population.

Esophageal lesions following button-battery ingestion in children: Analysis of causes and proposals for preventive measures.

OBJECTIVES: To study recent cases of esophageal injury due to button-battery ingestion in children presenting in pediatric ENT emergency departments of the Paris area of France (Île-de-France region), in order to propose appropriate preventive measures. MATERIAL AND METHOD: A retrospective descriptive single-center study included all children under 15 years of age, presenting in pediatric ENT emergency departments between January 2008 and April 2014 for button-battery ingestion with esophageal impaction requiring emergency removal. RESULTS: Twenty-two boys and 4 girls, with a median age of 25 months, were included. Twenty-five of the 26 batteries had diameters of 20mm or more. Median esophageal impaction time was 7 hours 30 minutes (range, 2 to 72 hours). The complications rate was 23%. Mean hospital stay cost was €38,751 (range, €5130-119,737). The origin of the battery was known in 23 of the 26 cases: remote control without screw-secured compartment (42.3%), open battery pack (15.4%), children's toy (15.3%), camera (7.7%), watch (1 case) and hearing aid without screw-secured compartment (1 case). CONCLUSION: Esophageal lesions due to ingestion of button-batteries in children are almost always due to batteries larger than 20mm in diameter, mostly from devices with a poorly protected compartment, or batteries that are not individually packaged. These lesions cause serious complications in a quarter of cases and their management entails high health costs. Legislation requiring screw-secured compartments and individual blisters for batteries could have prevented 69.2% of the ingestions.

The public health resource utilization impact of airway foreign bodies in children.

OBJECTIVE: Quantify the resource utilization associated with airway foreign bodies in children in the United States using a national database and report observed trends over time. STUDY TYPE: Cross-sectional analysis of national inpatient database with weighted estimates. DATA SOURCE: The KID database (2000-2009). METHODS: ICD-9-DM codes for foreign body aspiration were used to identify patients to be included for investigation. Admission rates and charges were aggregated and compared among geographic region, location, and teaching hospital status. These factors were then also trended over time. RESULTS: From 2000 to 2009, airway foreign body diagnoses in children accounted for an estimated 4000 to 5000 admissions, resulting in a mean admission rate of 6.6 per 10,000 pediatric patients annually. Charges related to airway foreign bodies in children rose from a total of $93 million to $486 million in the observed period. There is an increasing trend over time of total charges per patient. Charges appear to be higher in urban locations and teaching hospitals. CONCLUSIONS: The public health and economic burden of pediatric airway foreign bodies appears to be rising. Further investigation may be helpful to examine factors that may be contributing to increasing charges and creating strategies to improve cost effectiveness, as well as why there seems to be increased resource utilization in urban locations and teaching hospitals.

Nasal foreign bodies in children in a pediatric hospital in Senegal: A three-year assessment.

OBJECTIVES: Nasal foreign bodies (NFB) constitute a common domestic accident in children. The objectives of the present study were to report the particularities of NFBs in children presenting at a pediatric hospital in Senegal, and to describe our therapeutic attitude. MATERIAL AND METHODS: A retrospective descriptive study included all under-15 year-olds presenting with NFB in the ENT department of the National Children's Hospital Center of Diamniadio, Senegal, between January 1, 2013 and December 31, 2015. Study variables comprised: age, gender, provenance, presenting symptoms, time to consultation, type of NFB, extraction method, and complications. RESULTS: 58 NFB cases were retrieved. Mean age was 3years 4months; 93% of patients were under 5 years old. There was female predominance of 53.45%: i.e., sex-ratio, 0.87. Location was in the right cavity in 43 patients (74.1%). The presenting symptom was purulent rhinorrhea in 51.7% of cases. Time to consultation was within 24hours in 17.24% of cases. NFB type was firstly foam rubber (29.3%), followed by grain (20.7%). Extraction was performed in consultation in 84.5% of cases and in the operating room in 15.5%. Morbidity was 22.41%: 17.24% epistaxis and 5.17% nasal infection. CONCLUSION: NFBs constitute a common domestic accident in under-5 year-olds. The rural Senegalese context shows delay in consultation.

Reasons for Apical Surgery Treatment in an Underserved New York City Population.

Endodontic retreatment often involves remaking restorations. The total cost may steer the treatment towards surgery. The aim of this study was to retrospectively record the reasons for performing apical surgery in an economically deprived patient population. The clinical reasons (59%) for apical surgery were most common, but the nonclinical (financial) reasons (41%) emerged as a major cause. The finding that 41% of the apicoectomies were performed because of nonclinical constraints is a high figure and may not reflect the situation generally. Still, economic factors potentially play a major role in the selection of surgical versus nonsurgical endodontic retreatment.

Assessing the Epidemiological Data and Management Methods of Body Packers Admitted to a Referral Center in Iran.

The incidence of smuggling and transporting illegal substances by internal concealment, also known as body packing, is on the rise. The clinical approach to such patients has been changed significantly over the past 2 decades. However, despite a recorded increase in body packing in general, there are controversies in the management of these patients. We aimed to gather data regarding the demographic characteristics, treatment, and outcome of body packers, which were that referred to Loghman Hakim Hospital, Tehran, Iran.The data of all body packers admitted to Loghman Hakim Hospital during 2010 to 2014 were evaluated retrospectively. Data regarding the demographic characteristics of the patients, findings of clinical imaging, treatment, and outcome were recorded.In this study, 175 individuals with a mean age of 31 ±â€Š10 years were assessed. The most common concealed substances were crack (37%), crystal (17%), opium (13%), and heroin (6%). According to the results of surgery and imaging (abdominal radiography or computed tomography), the most common place for concealment was stomach in 33.3% and 12% of cases, respectively. Imaging findings were normal in 18% of the individuals. Forty-eight (27%) patients underwent surgery. The main indications for surgery were clinical manifestations of toxicity (79%) and obstruction of the gastro-intestinal tract (17%). The most common surgical techniques were laparotomy and gastrotomy (50%). The mean duration of hospitalization was 3.8 ±â€Š4 days. The mortality rate was 3%.Conservative treatment of body packers seems to be the best treatment method. Careful monitoring of the patients for possible signs and symptoms of intoxication and gastro-intestinal obstruction is strongly recommended.

Comparing models for quantitative risk assessment: an application to the European Registry of foreign body injuries in children.

Risk Assessment is the systematic study of decisions subject to uncertain consequences. An increasing interest has been focused on modeling techniques like Bayesian Networks since their capability of (1) combining in the probabilistic framework different type of evidence including both expert judgments and objective data; (2) overturning previous beliefs in the light of the new information being received and (3) making predictions even with incomplete data. In this work, we proposed a comparison among Bayesian Networks and other classical Quantitative Risk Assessment techniques such as Neural Networks, Classification Trees, Random Forests and Logistic Regression models. Hybrid approaches, combining both Classification Trees and Bayesian Networks, were also considered. Among Bayesian Networks, a clear distinction between purely data-driven approach and combination of expert knowledge with objective data is made. The aim of this paper consists in evaluating among this models which best can be applied, in the framework of Quantitative Risk Assessment, to assess the safety of children who are exposed to the risk of inhalation/insertion/aspiration of consumer products. The issue of preventing injuries in children is of paramount importance, in particular where product design is involved: quantifying the risk associated to product characteristics can be of great usefulness in addressing the product safety design regulation. Data of the European Registry of Foreign Bodies Injuries formed the starting evidence for risk assessment. Results showed that Bayesian Networks appeared to have both the ease of interpretability and accuracy in making prediction, even if simpler models like logistic regression still performed well.

Surgical management and morbidity of pediatric magnet ingestions.

BACKGROUND: Foreign body ingestion remains a common reason for emergency room visits and operative interventions in the pediatric population. Rare earth magnet ingestion represents a low percentage of all foreign bodies swallowed by children; however, magnets swallowed in multiplicity can result in severe injuries. MATERIALS AND METHODS: Pediatric surgeons with membership in the Surgical Section of the American Academy of Pediatrics were surveyed to determine the magnitude and consequences of magnet ingestions in the pediatric population. RESULTS: About 100 (16%) participant responses reported on 99 magnet ingestions. The median age at ingestion was 3.7 y, and the majority of ingestions (71%) occurred after year 2010. Thirty-two children underwent endoscopy with successful removal in 70% of cases, and multiple magnets were found in 65% of these patients. Seventy-three children required either laparotomy (51) or laparoscopy (22) for magnet removal, and 90% of these children were discovered to have ingested more than one magnet. In addition, 17% of the children were found to have at least one perforation or fistula, and 34% of the children had multiple perforations or fistulae. Nine children required long-term care for their injuries including repeat endoscopies. One child died after hemorrhage from an esophago-aortic fistula. CONCLUSIONS: These results demonstrated the increasing need for magnet regulations and public awareness to prevent potentially serious complications.
