RESUMO

Background: Many children undergo allogeneic hematopoietic stem cell transplantation (HSCT) for the treatment of malignant and nonmalignant conditions. Unfortunately, pulmonary complications occur frequently post-HSCT, with bronchiolitis obliterans syndrome (BOS) being the most common noninfectious pulmonary complication. Current international guidelines contain conflicting recommendations regarding post-HSCT surveillance for BOS, and a recent NIH workshop highlighted the need for a standardized approach to post-HSCT monitoring. As such, this guideline provides an evidence-based approach to detection of post-HSCT BOS in children. Methods: A multinational, multidisciplinary panel of experts identified six questions regarding surveillance for, and evaluation of, post-HSCT BOS in children. A systematic review of the literature was undertaken to answer each question. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to rate the quality of evidence and the strength of recommendations. Results: The panel members considered the strength of each recommendation and evaluated the benefits and risks of applying the intervention. In formulating the recommendations, the panel considered patient and caregiver values, the cost of care, and feasibility. Recommendations addressing the role of screening pulmonary function testing and diagnostic tests in children with suspected post-HSCT BOS were made. Following a Delphi process, new diagnostic criteria for pediatric post-HSCT BOS were also proposed. Conclusions: This document provides an evidence-based approach to the detection of post-HSCT BOS in children while also highlighting considerations for the implementation of each recommendation. Further, the document describes important areas for future research.

RESUMO

OBJECTIVE: To assess the efficacy of interarytenoid injection augmentation (IAIA) and the ability of IAIA to predict response to interarytenoid suture augmentation (IASA) based on diet advancement on video fluoroscopic swallow studies (VFSS). METHODS: Retrospective cohort analysis of patients with persistent pharyngeal dysphagia at a tertiary children's hospital with VFSS pre- and post-IAIA were included between March 2011 and June 2019. RESULTS: Median age of the 229 patients was 2.2 years (5.8 months-19 years). Interarytenoid mucosal height (IAMH) was found to be above the false vocal folds in 112 patients (53.4%) and at true vocal folds in 10 (4.9%) patients. On VFSS post-IAIA, 95 (41.5%) patients were successfully advanced in recommended diet consistency, 115 (50.2%) were stable, and 19 (8.3%) needed thicker consistency. Paired t-tests on pre- and post-operative consistency scores showed significant improvement, p-value of <0.0001, 95% confidence interval (CI; 0.50-0.85). Poisson regression found no covariates with significant association with improvement on IAIA. For IASA patients, 35/60 (58.3%) improved on post-op VFSS. Paired t-tests on pre- and post-operative consistency scores showed significant improvement, p-value of <0.0001, 95% CI (0.63-1.33). Positive predictive value for IAIA predicting response to IASA was 77% with positive likelihood ratio of 2.3. The response to IAIA versus no response to IAIA likelihood ratios were found to have a statistically significant difference (p < 0.05). CONCLUSIONS: Our study suggests IAIA yields objective improvement in swallow function on VFSS in nearly half of our patients and may be a reliable diagnostic tool to predict response to IASA in patients with persistent pharyngeal dysphagia with or without a laryngeal cleft.

RESUMO

OBJECTIVE: Suprastomal collapse and granulation are common sequelae of pediatric tracheostomy. We present the first measure of suprastomal obstructive pathology, the Seattle Suprastomal Safety Score (5S), an instrument with 2 domains: collapse and granulation. STUDY DESIGN: Cross-sectional repeated testing survey. SETTING: Electronic survey. METHODS: A library of images was assembled from still pictures of the suprastomal area in 50 patients who previously underwent trachea-bronchoscopy at a quaternary children's hospital. Five pediatric otolaryngologists and 2 pediatric pulmonologists reviewed the images in random, blinded fashion and provided 5S scores. Participants repeated this process 2 to 4 weeks later. Interrater agreement was calculated with an intraclass correlation coefficient (ICC) with a 2-way random-effects model and Fleiss's κ. Intrarater agreement was measured with an ICC using a 2-way mixed-effects model as well as with test-retest correlations using Spearman rank coefficient. All measures were performed separately on collapse and granulation domains. RESULTS: ICC for interrater agreement was 0.88 (95% CI, 0.82-0.93) for collapse and 0.97 (95% CI, 0.96-0.98) for granulation, indicating almost perfect agreement. Fleiss's κ demonstrated moderate agreement for collapse and almost perfect agreement for granulation. ICC for intrarater agreement was 0.95 (95% CI, 0.93-0.97) and 0.99 (95% CI, 0.98-0.99) for collapse and granulation, respectively, indicating almost perfect agreement. Spearman rank correlation for test-retest demonstrated substantial agreement for collapse and almost perfect agreement for granulation. CONCLUSION: The 5S demonstrates excellent interrater and intrarater agreement, making it highly reliable as a novel measure of suprastomal collapse and granulation in tracheostomy-dependent pediatric patients.

RESUMO

BACKGROUND: Hematopoietic Stem Cell Transplant (HSCT) is an established treatment for malignant and non-malignant conditions and pulmonary disease is a leading cause of late term morbidity and mortality. Accurate and early detection of pulmonary complications is a critical step in improving long term outcomes. Existing guidelines for surveillance of pulmonary complications post-HSCT contain conflicting recommendations. AIM: To determine the breadth of current practice in monitoring for pulmonary complications of pediatric HSCT. METHODS: An institutional review board approved, online, anonymous multiple-choice survey was distributed to HSCT and pulmonary physicians from the United States of America and Australasia using the REDcap platform. The survey was developed by members of the American Thoracic Society Working Group on Complications of Childhood Cancer, and was designed to assess patient management and service design. RESULTS: A total of 40 (34.8%) responses were received. The majority (62.5%) were pulmonologists, and 82.5% were from the United States of America. In all, 67.5% reported having a protocol for monitoring pulmonary complications and 50.0% reported adhering "well" or "very well" to protocols. Pulmonary function tests (PFTs) most commonly involved spirometry and diffusion capacity for carbon monoxide. The frequency of PFTs varied depending on time post-HSCT and presence of complications. In all, 55.0% reported a set threshold for a clinically significant change in PFT. CONCLUSIONS: These results illustrate current variation in surveillance for pulmonary complications of pediatric HSCT. The results of this survey will inform development of future guidelines for monitoring of pulmonary complications after pediatric HSCT.

RESUMO

OBJECTIVES/HYPOTHESIS: The Seattle Children's Hospital implemented the Trach Safe Initiative to improve airway safety in tracheostomy-dependent children (TDC). A key tenet of this initiative is surveillance endoscopy. The objectives of this study were to describe the prevalence of abnormal airway changes in TDC, identify risk factors for these changes, and describe the frequency of airway interventions. STUDY DESIGN: Retrospective case series. METHODS: This is a review of children 0 to 21 years old who underwent tracheostomy and surveillance endoscopy from February 1, 2014 to January 1, 2019. Descriptive statistics were used to report the prevalence of abnormal airway changes and interventions following tracheostomy. Pearson χ2 tests and logistic regression were used to identify risk factors for the development of abnormal changes. RESULTS: There were 127 children identified. The median time from tracheostomy to initial surveillance endoscopy was 1.6 months (interquartile range = 1.3-2.4 months). At initial endoscopy, 86.6% of patients had at least one abnormal airway finding. The most common findings were subglottic edema/stenosis (57.3%), glottic edema (37.3%), and suprastomal granulation tissue (31.8%). Prematurity and a history of failed extubations were significantly associated with abnormal findings on endoscopy (odds ratio [OR] = 7.2, P = .01 and OR = 4.1, P = .03, respectively). Of those with abnormal findings, 32.7% underwent an intervention to improve airway patency and safety. The most common interventions performed were suprastomal granuloma excision (44.4%), steroid injection (22.2%), and balloon dilation of the glottis or subglottis (19.4%). CONCLUSIONS: The prevalence of early abnormal airway changes in TDC is high, particularly in young children with a history of prematurity and failed extubation.

RESUMO

OBJECTIVE: To describe the Trach Safe Initiative and assess its impact on unanticipated tracheostomy-related mortality in outpatient tracheostomy-dependent children (TDC). METHODS: An interdisciplinary team including parents and providers designed the initiative with quality improvement methods. Three practice changes were prioritized: (1) surveillance airway endoscopy prior to hospital discharge from tracheostomy placement, (2) education for community-based nurses on TDC-focused emergency airway management, and (3) routine assessment of airway events for TDC in clinic. The primary outcome was annual unanticipated mortality after hospital discharge from tracheostomy placement before and after the initiative. RESULTS: In the 5 years before and after the initiative, 131 children and 155 children underwent tracheostomy placement, respectively. At the end of the study period, the institution sustained Trach Safe practices: (1) surveillance bronchoscopies increased from 104 to 429 bronchoscopies, (2) the course trained 209 community-based nurses, and (3) the survey was used in 488 home ventilator clinic visits to identify near-miss airway events. Prior to the initiative, 9 deaths were unanticipated. After Trach Safe implementation, 1 death was unanticipated. Control chart analysis demonstrates significant special-cause variation in reduced unanticipated mortality. DISCUSSION: We describe a system shift in reduced unanticipated mortality for TDC through 3 major practice changes of the Trach Safe Initiative. IMPLICATION FOR PRACTICE: Death in a child with a tracheostomy tube at home may represent modifiable tracheostomy-related airway events. Using Trach Safe practices, we address multiple facets to improve safety of TDC out of the hospital.
