Risk Assessment and Early Mobilization Pathway Following Pediatric Tracheostomy: A Pilot Study.

OBJECTIVES/HYPOTHESIS: To confirm the standard of care pertaining to postoperative mobilization practices following initial tracheostomy, to establish face validity of novel early mobilization tools, and to conduct a safety and feasibility pilot study. STUDY DESIGN: Multi-institutional survey and prospective cohort study. METHODS: Experts at our tertiary-care children's hospital developed an Early Pediatric Mobility Pathway for tracheostomy patients utilizing a novel risk-assessment tool. Surveys were distributed to professional colleagues in similar children's hospitals to establish face validity and incorporate respondent feedback. Additional surveys were disseminated to tertiary-care children's hospitals across the country to establish the current standard of care, and a pilot study was conducted. RESULTS: Seventy-seven percent of respondents from tertiary hospitals across the country confirmed the standard of care to defer mobilization until the first trach change. Greater than 83% of the respondents used to establish face validity of the tools agreed with the clinical components and scoring structure. The safety and feasibility of early mobilization prior to initial trach change was confirmed with a pilot of 10 pediatric patients without any adverse events. CONCLUSIONS: Mobilization of pediatric patients prior to initial trach change is feasible and can be safe when risk factors are assessed by a multidisciplinary team.

Competency-Based Assessment Tool for Pediatric Esophagoscopy: International Modified Delphi Consensus.

OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric esophagoscopy with foreign body removal. STUDY DESIGN: Blinded modified Delphi consensus process. SETTING: Tertiary care center. METHODS: A list of 25 potential items was sent via the Research Electronic Data Capture database to 66 expert surgeons who perform pediatric esophagoscopy. In the first round, items were rated as "keep" or "remove" and comments were incorporated. In the second round, experts rated the importance of each item on a seven-point Likert scale. Consensus was determined with a goal of 7 to 25 final items. RESULTS: The response rate was 38/64 (59.4%) in the first round and returned questionnaires were 100% complete. Experts wanted to "keep" all items and 172 comments were incorporated. Twenty-four task-specific and 7 previously-validated global rating items were distributed in the second round, and the response rate was 53/64 (82.8%) with questionnaires returned 97.5% complete. Of the task-specific items, 9 reached consensus, 7 were near consensus, and 8 did not achieve consensus. For global rating items that were previously validated, 6 reached consensus and 1 was near consensus. CONCLUSIONS: It is possible to reach consensus about the important steps involved in rigid esophagoscopy with foreign body removal using a modified Delphi consensus technique. These items can now be considered when evaluating trainees during this procedure. This tool may allow trainees to focus on important steps of the procedure and help training programs standardize how trainees are evaluated. LEVEL OF EVIDENCE: 5. Laryngoscope, 131:1168-1174, 2021.

Competency-Based Assessment Tool for Pediatric Tracheotomy: International Modified Delphi Consensus.

OBJECTIVES/HYPOTHESIS: Create a competency-based assessment tool for pediatric tracheotomy. STUDY DESIGN: Blinded, modified, Delphi consensus process. METHODS: Using the REDCap database, a list of 31 potential items was circulated to 65 expert surgeons who perform pediatric tracheotomy. In the first round, items were rated as "keep" or "remove," and comments were incorporated. In the second round, experts were asked to rate the importance of each item on a seven-point Likert scale. Consensus criteria were determined a priori with a goal of 7 to 25 final items. RESULTS: The first round achieved a response rate of 39/65 (60.0%), and returned questionnaires were 99.5% complete. All items were rated as "keep," and 137 comments were incorporated. In the second round, 30 task-specific and seven previously validated global rating items were distributed, and the response rate was 44/65 (67.7%), with returned questionnaires being 99.3% complete. Of the Task-Specific Items, 13 reached consensus, 10 were near consensus, and 7 did not achieve consensus. For the 7 previously validated global rating items, 5 reached consensus and two were near consensus. CONCLUSIONS: It is feasible to reach consensus on the important steps involved in pediatric tracheotomy using a modified Delphi consensus process. These items can now be considered to create a competency-based assessment tool for pediatric tracheotomy. Such a tool will hopefully allow trainees to focus on the important aspects of this procedure and help teaching programs standardize how they evaluate trainees during this procedure.

Application-Based Translaryngeal Ultrasound for the Assessment of Vocal Fold Mobility in Children.

OBJECTIVE: To compare the evaluation of vocal fold mobility between flexible nasal laryngoscopy (FNL) and a handheld application-based translaryngeal ultrasound (TLUS) platform. STUDY DESIGN: Prospective analysis included patients with unknown vocal fold mobility status who underwent FNL and TLUS. SETTING: Tertiary referral center. SUBJECTS AND METHODS: TLUS was performed on 23 consecutive children (<18 years old) presenting for laryngoscopy due to unknown vocal fold mobility status. After the recording of three 10-second TLUS videos as well as FNL, the study was divided into 2 parts: parental assessment of laryngeal ultrasound at the time of patient evaluation and random practitioner assessment of ultrasound videos. RESULTS: We describe 23 patients who underwent TLUS and FNL. Ten patients (43.5%) had normal vocal fold function bilaterally, and 13 (56.5%) had either left or right vocal fold immobility. Family members and physicians correctly identified the presence and laterality of impaired vocal fold mobility in 22 of 23 cases (κ = 0.96). The sensitivity, specificity, positive predictive value, and negative predictive value of FLUS in diagnosing vocal fold immobility were 92.3%, 100%, 100%, and 90.9%, respectively. Random practitioners accurately identified the presence and laterality of vocal fold immobility under all circumstances. CONCLUSION: A handheld application-based ultrasound platform is both sensitive and specific in its ability to identify vocal fold motion impairment. Portable handheld TLUS has the potential to serve as a validated screening examination, even by inexperienced providers, and in specific cases may obviate the need for an invasive transnasal laryngoscopy.

Assessment of airway abnormalities in patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals.

BACKGROUND: Children with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals (TOF/MAPCAs) are at risk for post-operative respiratory complications after undergoing unifocalisation surgery. Thus, we assessed and further defined the incidence of airway abnormalities in our series of over 500 children with TOF/MAPCAs as determined by direct laryngoscopy, chest computed tomography (CT), and/or bronchoscopy. METHODS: The medical records of all patients with TOF/MAPCAs who underwent unifocalisation or pulmonary artery reconstruction surgery from March, 2002 to June, 2018 were reviewed. Anaesthesia records, peri-operative bronchoscopy, and/or chest CT reports were reviewed to assess for diagnoses of abnormal or difficult airway. Associations between chromosomal anomalies and airway abnormalities - difficult anaesthetic airway, bronchoscopy, and/or CT findings - were defined. RESULTS: Of the 564 patients with TOF/MAPCAs who underwent unifocalisation or pulmonary artery reconstruction surgery at our institution, 211 (37%) had a documented chromosome 22q11 microdeletion and 28 (5%) had a difficult airway/intubation reported at the time of surgery. Chest CT and/or peri-operative bronchoscopy were performed in 234 (41%) of these patients. Abnormalities related to malacia or compression were common. In total 35 patients had both CT and bronchoscopy within 3 months of each other, with concordant findings in 32 (91%) and partially concordant findings in the other 3. CONCLUSION: This is the largest series of detailed airway findings (direct laryngoscopy, CT, and bronchoscopy) in TOF/MAPCAS patients. Although these findings are specific to an at-risk population for airway abnormalities, they support the utility of CT and /or bronchoscopy in detecting airway abnormalities in patients with TOF/MAPCAs.
