Aerodigestive Programs Enhance Outcomes in Pediatric Patients

Assessment of risk factors for adverse events in analgosedation for pediatric endoscopy: A 10-year retrospective analysis

OBJECTIVES

Data regarding the occurrence of complications specifically during pediatric anesthesia for endoscopic procedures is limited. By evaluating such data, factors could be identified to assure proper staffing and preparation to minimize adverse events and improve patient safety during flexible endoscopy.

METHODS

This retrospective cohort study included children undergoing anesthesia for gastroscopy, colonoscopy, bronchoscopy, or combined endoscopic procedures over 10-year period. The primary study aim was to evaluate the incidence of complications and identify risk factors for adverse events.

RESULTS

Overall, 2064 endoscopic procedures including 1356 gastroscopies (65.7%), 93 colonoscopies (4.5%), 235 bronchoscopies (11.4%), and 380 combined procedures (18.4%) were performed. Of the 1613 patients, 151 (7.3%) patients exhibited an adverse event, with respiratory complications being the most common (65 [3.1%]). Combination of gastrointestinal endoscopies did not lead to an increased adverse event rate (gastroscopy: 5.5%, colonoscopy: 3.2%). Diagnostic endoscopy as compared to interventional had a lower rate. If bronchoscopy was performed, the rate was similar to that of bronchoscopy alone (19.5% vs. 20.4%). Age < 5.8 years or body weight less than 20 kg, bronchoscopy, American Society of Anesthesiologists status ≥ 2 or pre-existing anesthesia-relevant diseases, and urgency of the procedure were independent risk factors for adverse events. For each risk factor, the risk for events increased 2.1-fold [1.8-2.4].

CONCLUSIONS

This study identifies multiple factors that increase the rate of adverse events associated anesthesia-based endoscopy. Combined gastrointestinal procedures did not increase the risk for adverse events while combination of bronchoscopy to gastrointestinal endoscopy showed a similar risk as bronchoscopy alone.

Global State of the Art and Science of Childhood Dysphagia: Similarities and Disparities in Burden

Feeding/swallowing and airway protection are complex functions, essential for survival, and continue to evolve throughout the lifetime. Medical and surgical advances across the globe have improved the long-term survival of medically complex children at the cost of increasing comorbidities, including dysfunctional swallowing (dysphagia). Dysphagia is prominent in children with histories of preterm birth, neurologic and neuromuscular diagnoses, developmental delays, and aerodigestive disorders; and is associated with medical, health, and neurodevelopmental problems; and long-term socioeconomic, caregiver, health system, and social burdens. Despite these survival and population trends, data on global prevalence of childhood dysphagia and associated burdens are limited, and practice variations are common. This article reviews current global population and resource-dependent influences on current trends for children with dysphagia, disparities in the availability and access to specialized multidisciplinary care, and potential impacts on burdens. A patient example will illustrate some questions to be considered and decision-making options in relation to age and development, availability and accessibility to resources, as well as diverse cultures and family values. Precise recognition of feeding/swallowing disorders and follow-up intervention are enhanced by awareness and knowledge of global disparities in resources. Initiatives are needed, which address geographic and economic barriers to providing optimal care to children with dysphagia.

Assessment of families' experience with care integration within an aerodigestive program

OBJECTIVES

The objective of this study was to assess if enrollment in a pediatric multidisciplinary aerodigestive program significantly impacted families' experiences with care integration.

METHODS

A previously validated 48-question Pediatric Integrated Care Survey (PICS) was administered in a cross-sectional manner to both new (new-ADC) and established (est-ADC) patients presenting for an outpatient Aerodigestive Center visit at Boston Children's Hospital. Survey results were grouped into the following five care coordination domains: (1) access to care, (2) care goal creation/planning, (3) family impact, (4) communication with health care providers, and (5) team functioning. Families were asked to rate their care integration experiences in the prior 12 months using yes/no and Likert-based questions. Comparisons were analyzed using logistic regression. Factor analysis was also performed.

RESULTS

Ninety patient families were surveyed: 54 (60%) est-ADC patients and 36 (40%) new-ADC patients. Est-ADC patients reported higher levels of experience with team functioning, provider awareness of prior testing, provider communication, and access to alternative methods of communication. Self-identified non-White patients reported lower satisfaction in team functioning and provider understanding of their child's long-term care plan. No significant differences in care integration experiences before and after the onset of the coronavirus pandemic were seen.

CONCLUSIONS

Patients enrolled in aerodigestive centers experienced improved care integration, most significantly in provider communication and team functioning. Despite these improvements, self-identified non-White families reported a lower care integration experience.

Association of Discharge Location Following Pediatric Tracheostomy with Social Determinants of Health: A National Analysis

OBJECTIVE

To evaluate the breakdown of discharge locations among pediatric tracheostomy patients and determine the impact of demographic variables and social determinants of health.

STUDY DESIGN

Retrospective review of the 2016 and 2019 Healthcare Cost and Utilization Project Kids' Inpatient Database (HCUP KID).

SETTING

A total of 4000 United States community hospitals, defined as short-term, non-Federal, general, and specialty hospitals.

METHODS

ICD-10-PCS, ICD-10 CM codes, and HCUP data elements were selected for patients and variables of interest. Bivariate comparisons were performed using Rao-Scott Chi-square tests; significance levels in post hoc pairwise testing were adjusted using Bonferroni adjustment. Multinomial generalized logistic regression models were used to determine the average annual odds ratio (OR) of 3 dispositions at discharge relative to discharge home for self-care.

RESULTS

Patients aged 11-17, patients from large metropolitan areas, and patients of "Other" race have an increased odds of discharge to a short- or long-term care facility (all P < .001). Weekend admissions, nonelective admissions, patients in Northeast hospitals, and patients at urban nonteaching hospitals are also more likely to be discharged to a short- or long-term care facility (all P < .001). Mean and median total costs of admission were $424,387 and $243,479, respectively, with a median total charge of $854,499.

CONCLUSION

Among pediatric tracheostomy patients, demographic factors that affect discharge disposition include age, community type, and race, and significant hospital factors include day and type of admission, geographic region, and hospital type. Hospitalizations are associated with high overall costs and charges to the patient, which are increasing over time.

Recent Advances in the Genetic Pathogenesis, Diagnosis, and Management of Esophageal Atresia and Tracheoesophageal Fistula: A Review

Infants born with esophageal atresia and tracheoesophageal fistula, a complex congenital malformation occurring in 1/2500-4000 live births, may suffer threats to their cardiac, respiratory, and digestive health in addition to anomalies that may exist in the genitourinary and musculoskeletal systems. Optimal care for these patients throughout their lives is best achieved through a coordinated, multidisciplinary approach that our health care system is not always well-equipped to provide. This review, though not exhaustive, highlights the components of care that pertain to initial surgical reconstruction and subsequent diagnosis and management of the complications that are most frequently encountered. Authors from among the many specialties involved in the care of these patients summarize the current best practice with attention to the most recent advances. Assessment and improvement of quality of life and transition to adult specialists as children grow to adulthood is also reviewed.

Anesthesia for laryngotracheal reconstruction in children: A narrative review

Laryngotracheal stenosis, congenital or acquired, is a common cause of pediatric airway obstruction. Acquired subglottic stenosis frequently results from prolonged neonatal intubation. The clinical presentation of subglottic stenosis is variable, ranging from biphasic stridor and frequent upper respiratory infections to acute airway compromise. Optimal patient care requires clinical coordination within a multidisciplinary subspecialty team. Medical management includes optimizing respiratory status, gastroesophageal reflux, speech, feeding, nutrition therapies, and providing psychosocial support. If surgical intervention is required, the otolaryngologist, anesthesiologist, and perioperative team must collaborate closely to ensure successful operative outcomes. This narrative review of laryngotracheal stenosis will discuss the pathophysiology, clinical evaluation, medical management, and surgical interventions, and focus on the perioperative anesthetic considerations for children undergoing laryngotracheal reconstruction.

Characterization of combined endoscopies and aerodigestive care: An analysis of utilization and financial feasibility

BACKGROUND

Aerodigestive care is one model of multi-disciplinary care, which is a valuable tool for both providers and patients. Aerodigestive care models are associated with improved outcomes, reduced anesthesia exposure, reduction in hospital admissions, and fewer days of missed work or school. This is the first study to explore national usage and cost trends in combined endoscopy utilization to identify gaps in care and the potential for financial resource optimization.

METHODS

Data from the Healthcare Cost and Utilization Project (HCUP) Kid's Inpatient Sample (KID) was used from 2016 and 2019. Diagnoses and procedures were identified using ICD-10 codes, for patients with hospital length of stay less than 1 day. Demographic data were identified, and survey-weighted means and proportions were computed. Bivariate comparisons were made using Rao Scott Chi-Square tests. National estimates of charges were computed with discharge weights, developed using the American Hospital Association (AHA) universe.

KEY RESULTS

White, high-income patients, and those at urban teaching hospitals received the greatest proportion of combined endoscopic procedures. The cost/charges associated with combined endoscopies are less than for separate gastrointestinal (GI) or airway only endoscopies combined. However, combined procedures comprise a smaller share of national aggregate cost.

CONCLUSIONS

National utilization trends highlight racial and socioeconomic disparities and suggest differences in access based on hospital characteristics, despite the reduced cost/charges of the combined procedure. For patients with a need for combined aerodigestive procedures, there appears to be a cost-savings opportunity to increase efforts for combined procedures at the level of the clinician or hospital.

A multicenter study analyzing the impact of pre-existing comorbidities on laryngotracheal reconstruction (LTR) outcomes

INTRODUCTION

Comorbidities such as chronic lung disease and gastroesophageal reflux (GERD), prematurity, and numerous other conditions may impact the success of LTR. Single-center studies are limited in terms of patient numbers and may be underpowered.

OBJECTIVES

To analyze the impact of specific comorbidities on the operation-specific and overall surgical success of LTR in a large multicenter cohort and validate a predictive model for surgical success.

METHODS

A large retrospective multicenter 10-year review was undertaken to validate the data of a previous single-center study (Wertz et al. Laryngoscope 2020) which identified specific predictive comorbidities which impacted LTR outcomes. A Monte Carlo simulation based on the previous data set suggested that 300-400 cases would be needed to optimize the statistical power of a Bayesian model developed from the single-center data to predict surgical success. An IRB-approved data-sharing agreement was executed for 4 large U.S.

CENTERS

A virtual REDCap® data entry form inquired about patient characteristics that best predicted surgical success in the single-center model. These included demographics, surgical approaches, cardiac, airway, genetic, endocrine, musculoskeletal, gastrointestinal, and pulmonary comorbidities; details of the surgical procedures, and results of esophagogastroduodenoscopy (EGD), esophageal pH/impedance and flexible bronchoscopy with bronchioalveolar lavage (BAL) were included. Surgical success defined as successful decannulation or resolution of airway symptoms was recorded as single surgery success and overall success following open surgical revision surgery. Multivariate Bayesian analysis, logistical regression, and Kaplan-Meier analysis were performed.

RESULTS

542 patients were identified, including 165 from the single-center study and an additional 377 patients from the multicenter group. The median age was 36 months at the time of the most recent surgery. 70.9% of the LTRs were double-staged procedures. The overall success rate was 86.4% and operation-specific success rate was 69.2%. The specific comorbidities and aerodigestive test results that impacted success based on univariate analysis included staging, bronchiectasis, pulmonary hypertension, GERD, ASD, PDA, grade of stenosis, advanced levels of stenosis, Trisomy 21, MRSA, prior open surgery at another hospital, and gross appearance on EGD. Bayesian model averaging with backward selection was used to validate and refine a predictive model for surgical success with favorable receiver operating curve characteristics - AUC values of 0.827 for single surgery success and 0.797 for overall success.

DISCUSSION

With over 500 patients reviewed, this was the largest multicenter study of LTR to date, which elucidated the impact of comorbidities on success with LTR and was able to improve upon the predictive modeling based on single-center data. Patient factors are most critical in the outcome of LTR. Stage and levels of stenosis, as well as pulmonary and GI conditions most strongly impact the likelihood of success. Future prospective case-control studies will be performed to further optimize the current model for outcome prediction and patient management.

The follow up of complex infants in an aerodigestive clinic

The current available literature evaluating pediatric multidisciplinary aerodigestive programs for the management of aerodigestive disorders in infants was reviewed. Multidisciplinary aerodigestive programs have emerged to provide coordinated and comprehensive care for the growing population of children with aerodigestive conditions, including complex airway, pulmonary, gastrointestinal, and feeding disorders, which are prevalent among infants discharged from the neonatal intensive care unit (NICU). The team approach central to aerodigestive clinics offers a comprehensive diagnostic workup and unified management plan through consolidated interdisciplinary clinics, combined endoscopic procedures, and regular team discussions, leading to improved resource utilization and health care outcomes. We review common conditions presenting in the NICU that benefit from the aerodigestive model of care, including esophageal atresia, prematurity, bronchopulmonary dysplasia with or without tracheostomy or ventilator dependence, and dysphagia.

Aerodigestive clinic reduces emergency department and primary care utilization and increases access to ancillary and specialty care

OBJECTIVE

The study aimed to evaluate the effect of the aerodigestive clinic (ADC) on healthcare utilization.

STUDY DESIGN

Retrospective quality improvement project; before and after.

SETTING

The ADC at Tripler Army Medical Center (TAMC) in Honolulu, HI.

METHODS

We retrospectively analyzed the electronic medical records of children ≤17 years old seen in the ADC at TAMC between April 2015 and June 2019. The number of emergency department (ED), primary care (PC), specialty care (SC), ancillary care (AC), and teleconsult (TC) encounters were tallied before and after one year of the initial intake visit.

RESULTS

A total of 261 children were included during the study period. Comparing visits before aerodigestive evaluation to after aerodigestive evaluation, the total number of visits before and after were similar with significant changes in the distribution of encounters. The total number of ED (-38%) and PC (-40%) visits decreased significantly (p < 0.001 for both). The total number of other visits were found to have non-significant increases. PC visits accounted for nearly one-third (31%) of all visits prior to the initial ADC visit, but only 19% of visits after. PC visits decreased for all age groups. ED visits decreased by nearly half (-48.1%) for ages 1-17, but there was no change for <1-year olds.

CONCLUSION

There is a statistically significant reduction in the number of emergency department and primary care visits for patients seen in a multidisciplinary ADC. The distribution of visits differed strongly among age groups. These findings emphasize the positive impact that the multidisciplinary clinic has on healthcare utilization for pediatric aerodigestive patients.

Risk factors for return visits in children discharged with tracheostomy

STUDY OBJECTIVES

To determine associations between demographic and clinical characteristics and rate of unplanned returns to system (RTS) in pediatric patients discharged with tracheostomy.

METHODS

Medical records were examined for pediatric patients discharged after tracheostomy placement between January 1, 2011 and December 31, 2015. Exclusion criteria included death or decannulation prior to discharge and lack of follow-up through 180 days post-discharge. Readmissions were grouped by time interval after discharge (within 30 days or within 31-180 days). Chi-squared analysis and Fisher's Exact Test were utilized to determine associations between patient characteristics, rate and frequency of RTS, and type of admission (Emergency Department [ED] or inpatient [IP]).

RESULTS

One hundred twenty-one patients were eligible for the study, and 80 (66.1 %) had an unanticipated RTS during the follow-up period. Patients with early RTS had a higher total number of RTS. Patients with two or more RTS were more likely to be younger, while patients with five or more RTS were more likely to have greater organ system involvement and cardiovascular (CV) disease in particular. Patients presenting with GI diagnoses were more likely to be discharged from the ED. The rate of RTS remained constant throughout the time period examined.

CONCLUSION

Pediatric patients discharged with tracheostomy are medically complex and at high risk of RTS, especially for respiratory and GI problems. This risk does not decrease after the initial post-discharge period and long-term follow-up is warranted. Younger patients and patients with history of early RTS are at highest risk for repeat RTS and should be identified for closer outpatient care.

Multidisciplinary aerodigestive program at a children's hospital: A protocol for a prospective observational study

BACKGROUND

Children with complex chronic multisystemic diseases frequently require care from multiple pediatric subspecialists. The aerodigestive program is a multidisciplinary program that diagnoses and treats pediatric patients with complex multi-systematic problems affecting airway, breathing, feeding, swallowing, or growth. The aim of this study is to present the protocol of the aerodigestive program of a children's hospital.

METHODS AND DESIGN

This study is a prospective study to evaluate and compare the overall improvement of patients' objective and subjective conditions before and after the AeroDigestive Team (ADT) program. Among children from 1 month to 18 years of age, patients with complex problems of the airway, breathing, feeding, swallowing, or growth meeting at least two parameters of the inclusion criteria were enrolled. The overall process included referral based on the inclusion criteria, enrollment of ADT program with informed consents, interview and questionnaire for assessing patients' medical condition, prescheduling appointment, multi-specialists' evaluation, monthly team meetings, wrap-up discussion with the patients and family, therapeutic intervention, and follow-up at 6 months with the assessment of outcome measures. The outcome was evaluated objectively and subjectively. The objective outcome measure was divided into surgical or medical intervention, assessment of changes in medical condition, and follow-up study. Both caregiver interviews and questionnaires using a scoring system were used as subjective outcome measures before and after the ADT program. Children were scheduled to be followed-up at 6 months after the interventions or ADT meeting.

DISCUSSION

The aerodigestive program is expected to provide comprehensive and multidisciplinary management of children with complex airway and digestive tract disorders.

Assessing Pediatric Feeding Disorders by Domain in Complex Aerodigestive Patients

Objective: Pediatric feeding disorder (PFD) is defined as impaired oral intake, associated with dysfunction in at least one of four domains: medical, nutritional, feeding skill, and/or psychosocial. The pediatric aerodigestive patient presents with conditions impacting airway, breathing, feeding, swallowing, or growth. The objective of the study was to determine the prevalence of PFD and dysfunctional domain, in the aerodigestive patient presenting to a tertiary aerodigestive clinic.

Methods: Twenty-five charts from patients enrolled in Mayo Clinic Children’s Center Aerodigestive Program were retrospectively reviewed for documentation of dysfunction within the four feeding disorder domains. Results from the aerodigestive triple scope, functional endoscopic evaluation of swallow (FEES), and videofluoroscopic swallow study (VFSS) were recorded. Height and weight z-scores were compared between the initial assessment and 6-12 months later.

Results: Median age was 20 months (range 2-81 months). Of the patients, 100% (n = 25) had dysfunction in at least one PFD domain. The domain identified most frequently was medical dysfunction (96%; n = 24). Feeding dysfunction was observed in 76% (n = 19). Psychosocial dysfunction was observed in 76% (n = 19). Nutritional dysfunction was observed in 60% (n = 15). Dysfunction in three or greater domains was seen in 80% (n = 20). Weight z-score increased in 76% (n = 19) of patients 6 to 12 months after the initial aerodigestive evaluation.

Conclusion: Aerodigestive patients frequently have PFD and utilizing the consensus definition of PFD at intake may enhance clinical assessment and therapeutic evaluation, and provide a framework to measure outcomes in this heterogeneous patient population.

Development of a Multidisciplinary Aerodigestive Program: An Institutional Experience

We share our experience on the implementation of a multidisciplinary aerodigestive program comprising an aerodigestive team (ADT) so as to evaluate its feasibility. We performed a retrospective chart review of the patients discussed at the monthly ADT meetings and analyzed the data. A total of 98 children were referred to the ADT during the study period. The number of cases increased steadily from 3.5 cases per month in 2019 to 8.5 cases per month in 2020. The median age of patients was 34.5 months, and 55% were male. Among the chronic comorbidities, neurologic disease was the most common (85%), followed by respiratory (36%) and cardiac (13%) disorders. The common reasons for consultation were suspected aspiration (56%), respiratory difficulty (44%), drooling/stertor (30%), regurgitation/vomiting (18%), and feeding/swallowing difficulty (17%). Following discussions, 58 patients received active interventions, including fundoplication, gastrostomy, laryngomicrosurgery, tracheostomy, and primary dilatation of the airway. According to the questionnaire of the caregiver, the majority agreed that the main symptoms and quality of life of patients had improved (88%), reducing the burden on caregivers (77%). Aerodigestive programs may provide comprehensive and multidisciplinary management for children with complex airway and digestive tract disorders.

Working as a team in airway surgery: History, present and perspectives

Teamwork is one of the most important trend in modern medicine. Airway team were created in many places to respond in a multidisciplinary and coordinated way to challenging clinical problems which were beyond the possibility of an individual management. In this chapter, we illustrate the historical steps leading to the development of an airway team in a pediatric referral hospital, describe the present teamwork activity defining the key points for the creation of a team and discussing different organization models; finally we delineate possible future directions for the airway teams in the globalized world.

Impact of Pre-operative Multidisciplinary Evaluation on Laryngotracheal Reconstruction Outcomes

OBJECTIVE/HYPOTHESIS

Determine if diagnostic findings from pre-operative multidisciplinary evaluations are associated with single surgery or overall success rates in pediatric laryngotracheal reconstruction (LTR).

STUDY DESIGN

Retrospective cohort.

METHODS

Retrospective cohort study of patients undergoing LTR at a tertiary care children's hospital between January 01, 2008 and December 31, 2017. Success is defined as decannulation rate if tracheostomy present, and resolution of symptoms if tracheostomy not present. Cohorts compared were those who did and did not receive pulmonary and gastrointestinal preoperative testing. Multivariate, logistic regression, and Kaplan Meier analyses performed.

RESULTS

About 165 children were included in the study. Median age was 3 years at the time of surgery; 73% of LTRs were double-stage procedures. Single surgery and overall success rates were 75% and 87%, respectively. After adjusting for severity of stenosis and surgical approach, performing esophagogastroduodenoscopy (EGD) and normal gross appearance on EGD were associated with increased single surgery (P = .01, .005) and overall success (P = .005, .0003). Performing pH probe and normal EGD biopsy results was associated with increased overall success (P = .03, .007). Asthma and musculoskeletal comorbidities, postoperative complications, and need for postoperative balloon dilation were associated with decreased success. No other comorbidities evaluated impacted success.

CONCLUSIONS

Aerodigestive comorbidities are common in children undergoing LTR, and preoperative multidisciplinary workup often results in changes in management. After adjusting for grade and level of stenosis and staged approach, performing EGD and pH/impedance probe as well as normal gross and microscopic EGD findings was independently associated with increased LTR surgical success.

Multidisciplinary approach to paediatric aerodigestive disorders: A single-centre longitudinal observational study

AIM

Aerodigestive clinics (ADCs) are multidisciplinary programmes for the care of children with complex congenital or acquired conditions affecting breathing, swallowing and growth. Our objective was to describe the demographic, clinical, etiological and investigational profile of children attending the inaugural ADC at a tertiary paediatric centre in Queensland.

METHODS

Children referred to the ADC at Queensland Children's Hospital from August 2018 to December 2019 were included. Data on clinical, growth and lung function parameters, bronchoscopy and upper gastrointestinal endoscopy findings, thoracic imaging and comorbidities were retrospectively analysed.

RESULTS

Fifty-six children (median (range) age 4 years (3 months-15 years); 18 female) attended the ADC during this 17-month period. Forty-six (82%) children had previous oesophageal atresia with tracheo-oesophageal fistula; 43 of these were type C. Previous isolated oesophageal atresia, congenital diaphragmatic hernia and congenital pulmonary malformation were the underlying disorder in three (5%) children each, with one child having a repaired laryngeal cleft. Vertebral Anal Tracheo Esophageal Renal Limb anomalies (VACTERL)/Vertebral Anal Tracheo Esophageal renal anomalies (VATER) association was seen in 21 (38%) children. Growth was adequate (median weight and body mass index z-score -0.63 and -0.48, respectively). Thirty-four (61%) children reported ongoing wet cough, with 12 (21%) requiring previous hospital admission for lower respiratory tract infection. Fourteen (25%) had bronchiectasis on computed tomography chest and 33 (59%) had clinical tracheomalacia, apparent on bronchoscopic examination in 21 patients. Dysphagia was reported in 15 (27%) children, 11 (20%) were gastrostomy feed-dependent and 5 (9%) had biopsy-proven eosinophilic oesophagitis.

CONCLUSION

High proportion of children attending the ADC have ongoing respiratory symptoms resulting in chronic pulmonary suppuration and bronchiectasis. Potential benefits of this model of care need to be studied prospectively to better understand the outcomes.
