Pediatric tracheostomy speaking valves: A multidisciplinary protocol leads to earlier initial trials.

Early speaking valve application in children with tracheostomies is encouraged for language development. Whether an institutional multidisciplinary protocol impacts the patient population and timelines for which a speaking valve is trialed has not been studied. This retrospective study compared speaking valve trials performed at a pediatric quaternary hospital over a 12-year period. Timelines (time between tracheostomy insertion, speech-language pathologist (SLP) consultation, speaking valve order, and trial) and patient characteristics (demographics, tracheostomy classification, and feeding status) were collected. Medians (IQRs) compared timelines before and after a protocol was instituted and compared the timelines between tracheostomy classifications. Median time between tracheostomy insertion and SLP consultation did not change: before protocol-1.8 (7.7) months and after protocol-1.8 (2.4) months. Time between tracheostomy insertion and speaking valve trial decreased: before protocol-34.1 (40.5) months and after protocol-12.9 (8.4) months. Time between tracheostomy insertion and trial was not different between tracheostomy classifications: upper airway obstruction-16.0 (27.1) months, complex medical condition-36.3 (45.8) months, and invasive ventilation-17.5 (22.3) months. An institutional multidisciplinary protocol decreases the time between tracheostomy insertion and speaking valve trial, regardless of the reason the tracheostomy is needed in the pediatric population.

Chronic tracheostomy care of ventilator-dependent and -independent children: Clinical practice patterns of pediatric respirologists in a publicly funded (Canadian) healthcare system.

OBJECTIVES: To describe the current clinical practice patterns of Canadian pediatric respirologists at pediatric tertiary care institutions regarding chronic tracheostomy tube care and management of home invasive ventilation. METHODS: A pediatric respirologist/pediatrician with expertise in tracheostomy tube care and home ventilation was identified at each Canadian pediatric tertiary care center to complete a 59-item survey of multiple choice and short answer questions. Domains assessed included tracheostomy tube care, caregiver competency and home monitoring, speaking valves, medical management of tracheostomy complications, decannulation, and long-term follow-up. RESULTS: The response rate was 100% (17/17) with all Canadian tertiary care pediatric centers represented and heterogeneity of practice was observed in all domains assessed. For example, though most centers employ Bivona™ (17/17) and Shiley™ (15/17) tracheostomy tubes, variability was observed around tube change, re-use, and cleaning practices. Most centers require two trained caregivers (14/17) and recommend 24/7 eyes on care and oxygen saturation monitoring. Discharge with an emergency tracheostomy kit was universal (17/17). Considerable heterogeneity was observed in the timing and use of speaking valves and speech-language assessment. Inhaled anti-pseudomonal antibiotics are employed by most centers (16/17) though the indication, agent, and protocol varied by center. Though decannulation practices varied considerably, the requirement of upper airway patency was universally required to proceed with decannulation (17/17) independent of ongoing ventilatory support requirements. CONCLUSION: Considerable variability in pediatric tracheostomy tube care practice exists across Canada. These results will serve as a starting point to standardize and evaluate tracheostomy tube care nationally.

Feasibility of split night polysomnography in children to diagnose and treat sleep related breathing disorders.

STUDY OBJECTIVES: The gold standard test for diagnosis of sleep related breathing disorders (SRBD) in children is diagnostic polysomnography (PSG). This is often followed by a titration PSG to identify optimal non-invasive ventilation (NIV) pressures. Access to pediatric PSG is limited, resulting in delays to diagnosis and initiation of treatment. Split-night PSGs (snPSG) combine a diagnostic and titration PSG into a single night study. Although described in adults, the pediatric literature on this topic is sparse. The objective of this study was to describe a large cohort of children who utilized snPSG to diagnose SRBD and initiate NIV. METHODS: This multi-center study analyzed clinical and PSG data from children with SRBD who had initiated NIV following a snPSG. Data from diagnostic and titration portions of the snPSG were analyzed separately. RESULTS: The study included 165 children who initiated NIV following a snPSG. The majority of children (61.8%) were initiated on NIV for upper airway obstruction. The population included children with medical complexity, including those with central nervous system disorders (17.0%), musculoskeletal/neuromuscular disorders (12.1%), and cardiac disorders (1.2%). Moderate to severe SRBD was present in 87.2% of children with a median apnea-hypopnea index (AHI) of 16.6 events/hour (IQR: 8.2, 38.2). The median AHI was reduced on treatment to 7.6 events/hour (IQR: 3.3, 17.1), with fewer subjects meeting criteria for severe SRBD. CONCLUSIONS: snPSG is technically feasible in children, facilitating the diagnosis of SRBD and initiation of NIV, even in those with high medical complexity.

Primary Care Pathway for Childhood Asthma: Protocol for a Randomized Cluster-Controlled Trial.

BACKGROUND: Asthma is the most common chronic condition in children. For many, the disease is inadequately controlled, which can burden the lives of children and their families as well as the health care system. Improved use of the best available scientific evidence by primary care practitioners could reduce the need for hospital care and improve quality of life and asthma control, thereby reducing overall costs to society and families. OBJECTIVE: The Primary Care Pathway for Childhood Asthma aims to improve the management of children with asthma by (1) providing primary care practitioners with an electronic guide (a clinical pathway) incorporated into the patient's electronic medical record, and (2) providing train-the-trainer education to chronic disease management health professionals to promote the provision of asthma education in primary care. METHODS: The research will utilize a pragmatic cluster-controlled design, quantitative and qualitative research methodologies, and economic evaluation to assess the implementation of a pathway and education intervention in primary care. The intervention will be analyzed for effectiveness, and if the results are positive, a strategy will be developed to implement delivery to all primary care practices in Alberta. RESULTS: The research has been successfully funded and ethics approvals have been obtained. Practice recruitment began fall 2015, and we expect all study-related activities to be concluded by March 2018. CONCLUSIONS: The proposed pathway and education intervention has the potential to improve pediatric asthma management in Alberta. The intervention is anticipated to result in better quality of care for equal or lesser cost.

Surgical versus nonsurgical interventions to relieve upper airway obstruction in children with Pierre Robin sequence.

BACKGROUND: Newborns with Pierre Robin sequence (PRS) often experience chronic intermittent hypoxemia/hypoventilation associated with airway obstruction. The heterogeneity of the severity of upper airway obstruction makes management a challenge; the optimal intervention in individual cases is not clear. OBJECTIVE: To investigate the prevalence of surgical/nonsurgical interventions for PRS at two children's hospitals. Patient characteristics and outcomes were examined. METHODS: The present retrospective chart review identified 139 patients with PRS born between 2000 and 2010. Demographic information, mode of airway management, associated anomalies and syndromes, polysomnography results, length of intensive care unit and hospital stay, complications and deaths were extracted. RESULTS: Interventions included prone positioning (alone [61%]), tongue-lip adhesion (45%), nasopharyngeal intubation (28%), continuous positive airway pressure (20%), tracheostomy (19%) and mandibular distraction osteogenesis (5%). Tracheostomies were more prevalent in syndromic patients (P=0.03). Patients who underwent tracheostomy had a lower birth weight (P=0.03) compared with newborns with other interventions. Patients who underwent surgical interventions had longer intensive care unit stays (P<0.001). No intervention was associated with a statistically significant likelihood of requiring a subsequent intervention. Thirty percent of patients underwent polysomnography, with a higher proportion of these using continuous positive airway pressure (n=15) (P<0.01). CONCLUSIONS: In the present descriptive study, patients with syndromic PRS or low birth weight underwent early intervention, which included a tracheostomy. Objective measures of airway obstruction were underutilized. Decision making regarding evaluation and management of upper airway obstruction in this population remains clinician and resource dependent. Reporting data obtained from a large cohort of PRS patients is important to compare experiences and motivate future studies investigating this complex condition.

Congenital central hypoventilation syndrome; safety of early transition to non-invasive ventilation.

Congenital central hypoventilation syndrome (CCHS) is a rare disorder of autonomic dysregulation, characterized by alveolar hypoventilation especially during sleep. As a result, lifelong ventilatory assistance is necessary in these patients. Many infants and children initially require positive pressure ventilation via tracheostomy for support. Associated complications and psychosocial pressure may prompt early transition to non-invasive ventilation. We present the details of a patient with CCHS who successfully transitioned from tracheostomy to bilevel positive airway pressure ventilation at an early age of 3 years.

Influenza vaccination among household contacts of children with cystic fibrosis and healthy children.

BACKGROUND: It is recommended that household contacts of children with cystic fibrosis and household contacts of children <2 years of age receive annual influenza vaccinations. There is little information documenting whether this recommendation is being followed. METHODS: A 20-question survey was distributed to caregivers of children with cystic fibrosis and to caregivers of healthy children <17 years of age seen in a Saskatoon (Saskatchewan) tertiary care centre. Survey questions addressed the influenza vaccination status of the child and household contacts. Respondents were also asked to rate the influence of various factors on the decision to vaccinate, using a 5-point Likert scale. RESULTS: Reported vaccination rates were 21%, 25% and 7% among household contacts of children with cystic fibrosis, children <2 years of age and children ≥2 years of age, respectively. Advice from their physician, belief that they were too healthy, and inconvenient times and locations of vaccination centres were significant influences when compared among the three groups. Other main deterrents to vaccination were belief that the vaccine does not prevent influenza and belief that its side effects are greater than its benefits. CONCLUSION: By understanding motivators and barriers to vaccination among household contacts of children with cystic fibrosis, effective strategies may be implemented to improve vaccination coverage against influenza. Strong recommendations by clinicians and improved access to vaccination centres are essential components in improving influenza vaccination coverage.

HISTORIQUE: Il est recommandé d'administrer annuellement le vaccin contre l'influenza aux contacts familiaux d'enfants ayant la fibrose kystique et d'enfants de moins de deux ans. Peu d'information étaye le respect de cette recommandation. MÉTHODOLOGIE: Un sondage de 20 questions a été distribué aux personnes qui s'occupent d'enfants ayant la fibrose kystique et d'enfants en santé de moins de 17 ans vus dans un centre de soins tertiaires de Saskatoon, en Saskatchewan. Les questions du sondage portaient sur le statut de vaccination contre l'influenza de l'enfant et des contacts familiaux. Les répondants ont également été invités à classer l'influence de divers facteurs sur la décision de vacciner, selon l'échelle de cinq points de Likert. RÉSULTATS: Les taux de vaccination déclarés s'élevaient à 21 %, 25 % et 7 % chez les contacts familiaux d'enfants atteints de la fibrose kystique, les enfants de moins de deux ans et les enfants de deux ans et plus, respectivement. Les conseils du médecin, la conviction qu'ils étaient en trop bonne santé, de même que les heures d'ouverture et le lieu peu pratiques des centres de vaccination étaient des influences importantes au sein des trois groupes. Les autres principaux freins à la vaccination étaient la conviction que le vaccin ne prévient pas l'influenza et la conviction que ses effets secondaires sont plus importants que ses avantages. CONCLUSION: Si on comprend les sources de motivation et les obstacles à la vaccination des contacts familiaux d'enfants atteints de la fibrose kystique, on pourra peut-être adopter des stratégies efficaces pour améliorer la couverture vaccinale contre l'influenza. Des recom-mandations convaincues de la part des cliniciens et un meilleur accès aux centres de vaccination sont des éléments essentiels à une amélioration de la couverture vaccinale.
