Paediatric home ventilatory support: the Auckland experience

Invasive versus non-invasive paediatric home mechanical ventilation: review of the international evolution over the past 24 years

BACKGROUND

Home mechanical ventilation (HMV) is the treatment for chronic hypercapnic alveolar hypoventilation. The proportion and evolution of paediatric invasive (IMV) and non-invasive (NIV) HMV across the world is unknown, as well as the disorders and age of children using HMV.

METHODS

Search of Medline/PubMed for publications of paediatric surveys on HMV from 2000 to 2023.

RESULTS

Data from 32 international reports, representing 8815 children (59% boys) using HMV, were analysed. A substantial number of children had neuromuscular disorders (NMD; 37%), followed by cardiorespiratory (Cardio-Resp; 16%), central nervous system (CNS; 16%), upper airway (UA; 13%), other disorders (Others; 10%), central hypoventilation (4%), thoracic (3%) and genetic/congenital disorders (Gen/Cong; 1%). Mean age±SD (range) at HMV initiation was 6.7±3.7 (0.5-14.7) years. Age distribution was bimodal, with two peaks around 1-2 and 14-15 years. The number and proportion of children using NIV was significantly greater than that of children using IMV (n=6362 vs 2453, p=0.03; 72% vs 28%, p=0.048), with wide variations among countries, studies and disorders. NIV was used preferentially in the preponderance of children affected by UA, Gen/Cong, Thoracic, NMD and Cardio-Resp disorders. Children with NMD still receiving primary invasive HMV were mainly type I spinal muscular atrophy (SMA). Mean age±SD at initiation of IMV and NIV was 3.3±3.3 and 8.2±4.4 years (p<0.01), respectively. The rate of children receiving additional daytime HMV was higher with IMV as compared with NIV (69% vs 10%, p<0.001). The evolution of paediatric HMV over the last two decades consists of a growing number of children using HMV, in parallel to an increasing use of NIV in recent years (2020-2023). There is no clear trend in the profile of children over time (age at HMV). However, an increasing number of patients requiring HMV were observed in the Gen/Cong, CNS and Others groups. Finally, the estimated prevalence of paediatric HMV was calculated at 7.4/100 000 children.

CONCLUSIONS

Patients with NMD represent the largest group of children using HMV. NIV is increasingly favoured in recent years, but IMV is still a prevalent intervention in young children, particularly in countries indicating less experience with NIV.

Finnish children who needed long-term home respiratory support had severe sleep-disordered breathing and complex medical backgrounds

AIM

No studies have described long-term paediatric home respiratory support in Nordic countries. We examined the clinical characteristics and long-term outcomes of paediatric patients who received continuous positive airway pressure, non-invasive-positive-pressure ventilation and invasive ventilation from a multidisciplinary home respiratory support team.

METHODS

Retrospective tertiary-level data were collected between 1 January 2010 and 31 December 2020 in Tampere University Hospital. These comprised patient demographics, treatment course and polysomnography-confirmed sleep-disordered breathing (SDB).

RESULTS

There were 93 patients (63.4% boys). The median age at treatment initiation was 8.4 (range 0.11-16.9) years. The patients had: neuromuscular disease (16.1%), central nervous system disease (14.0%), developmental disabilities and congenital syndrome (29.0%), lung-airway conditions (11.8%), craniofacial syndrome (15.1%) and severe obesity (14.0%). More than two-thirds had severe SDB (66.7%) and the most common one was obstructive sleep apnoea in 66.7%. We found that 92.5% received long-term therapy for more than 3 months and the mean treatment duration was 3.3 ± 2.7 years. A non-invasive mask interface was used in 94.7% of cases and 5.3% needed tracheostomy ventilation. More than a quarter (26.7%) achieved disease resolution during the study period.

CONCLUSION

Most children who needed long-term home respiratory support had complex conditions and severe, persistent SDB.

Going home: Clinician perspectives on decision-making in paediatric home mechanical ventilation

AIM

Despite a recent increase in the use of ventilators in the home setting for children with chronic respiratory failure, there is currently no unified approach for clinical decision-making for children requiring long-term mechanical ventilation. The purpose of this study is to understand the clinician's perspective on decision-making around home ventilation for children, and how home-based care contributes to successful outcomes in this population.

METHODS

We recruited physicians and home ventilation nurses with at least 2 years' experience working in an Australian paediatric tertiary home ventilation service using professional networks and snowball sampling. Semi-structured interviews were conducted by two researchers between February 2019 and June 2020. Interviews were audio-recorded, transcribed, and analysed using inductive content analysis.

RESULTS

Twenty-five individuals participated (17 physicians and 8 home ventilation nurses). Participants viewed themselves as impartial medical advocates in the decision-making process, believing the decision to initiate or cease ventilation belonged to the child's family. While participants held the child's quality of life as the cornerstone of decision-making, quality of life was subjective and family specific.

CONCLUSION

These findings provide insight into how clinicians working with children with chronic respiratory insufficiency approach the decision to introduce home-based ventilation. By understanding their role, strategies can be developed to assist them, leading to better outcomes for patients and families. Further research is needed to compare the perspectives of clinicians with the experience of ventilator-assisted children and families in Australia.

Trigger performance of five pediatric home ventilators and one ICU ventilator depending on circuit type and system leak in a physical model of the lung

BACKGROUND

The population of children with chronic respiratory failure requiring long-term mechanical ventilation in the home has grown worldwide. The optimal choice from an increasing number of home ventilators commercialized for children is often challenging for the attending physicians. The aim of the present study was to compare the trigger performance of five pediatric bilevel home ventilators and one intensive care unit ventilator depending on circuit type and system leak.

METHODS

The trigger performances of the ventilators were compared in combination with all compatible circuits using a physical model of the lung with increasing system leak. The flow generator simulated the patient's breathing effort with flow rates of 2.7-6.4 L/min at a frequency of 30 breaths/min. All ventilators were set to deliver 16 cmH₂ O inspiratory pressure support and 4 cmH₂ O positive end-expiratory pressure.

RESULTS

Trigger thresholds varied from 1.5 to 8 L/min, the pressure rise time to 90% of the maximum from 140 to 385 ms and the trigger work from 0.5 to 6.6 mbar · s. All devices had very short trigger delays below 40 ms. The leak compensation depended on the circuit type. The internal diameter of the circuit had no relevant impact on the trigger performance or the leak compensation.

CONCLUSION

We observed considerable differences in the triggering performance of the evaluated home ventilators depending on leak size and type of circuit. Therefore, an optimal combination of device and circuit should consider the patient's age and condition and the probability of system leak.

Pediatric Average Volume Assured Pressure Support

Average volume assured pressure support (AVAPS) is a modality of non-invasive ventilation that enables the machine to deliver a pre-set tidal volume by adjusting the inspiratory pressure support within a set range. Data on its use in the pediatric population are limited to case reports and single centre case series. This article reviews paediatric data on use of AVAPS and highlights the need for validation to help develop specific guidelines on use of AVAPS in children.

ERS Statement on pediatric long term noninvasive respiratory support

Long term noninvasive respiratory support, comprising continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV), in children is expanding worldwide, with increasing complexities of children being considered for this type of ventilator support and expanding indications such as palliative care. There have been improvements in equipment and interfaces. Despite growing experience, there are still gaps in a significant number of areas: there is a lack of validated criteria for CPAP/NIV initiation, optimal follow-up and monitoring; weaning and long term benefits have not been evaluated. Therapeutic education of the caregivers and the patient is of paramount importance, as well as continuous support and assistance, in order to achieve optimal adherence. The preservation or improvement of the quality of life of the patient and caregivers should be a concern for all children treated with long term CPAP/NIV. As NIV is a highly specialised treatment, patients are usually managed by an experienced pediatric multidisciplinary team. This Statement written by experts in the field of pediatric long term CPAP/NIV aims to emphasize on the most recent scientific input and should open up to new perspectives and research areas.

Using continuous nasal airway pressure in infants with craniofacial malformations

Obstructive sleep apnea (OSA) is common in infants and children with craniofacial malformations. Continuous positive airway pressure (CPAP) represents an effective noninvasive treatment for severe upper airway obstruction in these children, reducing the need of surgery or a tracheostomy. The decision to start CPAP should be discussed by a multidisciplinary team in order to decide the optimal individualized treatment strategy. CPAP initiation depends on patients' clinical characteristics and local practices, with an increase tendency towards an outpatient program. Follow-up and monitoring strategy varies among centers but benefits from the analysis of built-in software data in order to assess objective adherence and breathing parameters, reducing the need of in-hospital sleep studies. The possibility to wean CPAP should be periodically checked after surgical treatment or when spontaneous resolution is suspected. Finally, these infants with craniofacial malformations should have a long term follow up because of the risk of OSA recurrence over time.

Tough transitions: Family caregiver experiences with a pediatric long-term ventilation discharge pathway

OBJECTIVES

Discharging a child home on long-term ventilation (LTV) via tracheostomy is complex and involves multiple healthcare providers across healthcare sectors. To date, there has been a paucity of data with respect to the experiences of families transitioning a child home on LTV. Our objective was to explore the perceptions of family caregivers (FCs) who have completed a newly developed LTV discharge pathway as they transitioned home.

METHODS

We conducted 11 semi-structured interviews with FCs. Interviews focused on FC's experience with the training process, perception of competency from a knowledge and skill perspective, and opportunities for improvement. Interviews were audiotaped, transcribed verbatim, coded, and analyzed using an inductive thematic analysis approach.

RESULTS

Eight mothers and three fathers of ten children participated. Six primary themes were identified: (1) making an informed decision, (2) transitioning to rehabilitation, (3) building capacity for self-care, (4) coordinating case management, (5) readying for discharge home, and (6) experiencing home care.

CONCLUSION

Overall, FCs felt that the preparation and transition support obtained through the application of a standardized LTV discharge pathway allowed successful attainment of new knowledge and skills necessary to care for their child with LTV at home.

Risk factors for first nonscheduled hospital admissions of pediatric patients on home mechanical ventilation

OBJECTIVES

The number of children on home mechanical ventilation (HMV) has increased. Understanding the reasons for nonscheduled hospital admissions during HMV is critical. This study aims to investigate the risk factors of first nonscheduled hospital admissions of pediatric patients on HMV.

METHODS

A retrospective analysis of patients on HMV between May 1, 2014 and October 1, 2020 was performed. Patients' demographic characteristics, duration of the education of the primary caregiver; time of first nonscheduled visit; and type of HMV (noninvasive mechanical ventilation [NIV] or invasive mechanical ventilation [IMV]) were analyzed. The reasons for first nonscheduled hospital visits were categorized as respiratory problems and other reasons.

RESULTS

Of 97 patients, 41 were female (42.3%), and 70 (72%) were on IMV. The median age was 23 months (IQR, 10-91). Twenty-nine patients (30%), were admitted to hospital before scheduled visit with a mean duration of 18.1 ± 11.6 days; of them, 14 (48.2%) admitted because of respiratory problems. IMV increases the risk of first nonscheduled visit compared to NIV (OR, 16.3; 95% CI, 2.1-127.4; p = .008). If a caregiver spends less than 14 days in hospital for education, risk of nonscheduled visits increases (OR, 4.0; 95% CI, 1.5-11.2; p = .007).

CONCLUSION

A minimum 14 days seems to be necessary for education of the caregivers of the patients with HMV to reduce the number of nonscheduled visits, which is a burden for both patients and healthcare system.

Ventilatory support at home for children: A joint position paper from the Thoracic Society of Australia and New Zealand/Australasian Sleep Association

The goal of this position paper on ventilatory support at home for children is to provide expert consensus from Australia and New Zealand on optimal care for children requiring ventilatory support at home, both non-invasive and invasive. It was compiled by members of the Thoracic Society of Australia and New Zealand (TSANZ) and the Australasian Sleep Association (ASA). This document provides recommendations to support the development of improved services for Australian and New Zealand children who require long-term ventilatory support. Issues relevant to providers of equipment and areas of research need are highlighted.

A narrative review of the experience and decision-making for children on home mechanical ventilation

Technological advances in mechanical ventilation have made home care possible for children requiring long-term ventilation. However, there are ethical and logistical challenges to transitioning home. The aim of this narrative review is to identify the experiences of the children and their families and the decision-making process to embark on home mechanical ventilation. A systematic review of the literature using Medline and OVID databases was conducted. Children <18 years requiring non-invasive ventilation or tracheostomy with ventilation or continuous positive pressure ventilation were included. The initial search yielded 1351 results, 1017 after duplications were removed and 111 after abstracts were reviewed. After applying inclusion and exclusion criteria to full text analysis, 48 references were analysed. The children and families described home ventilation as facilitating better health and functional status. However, they concurrently described social isolation, stigma, financial stress and loss of independence. The decision-making process to embark on home ventilation needs more research.

Average volume-assured pressure support vs conventional bilevel pressure support in pediatric nocturnal hypoventilation: a case series

STUDY OBJECTIVES

Average volume-assured pressure support (AVAPS) is a modality of noninvasive ventilation that provides a targeted tidal volume by automatically adjusting the inspiratory pressure support within a set range. Pediatric studies evaluating the efficacy of AVAPS in treating nocturnal hypoventilation are confined to case reports. The aim of this study was to compare AVAPS to conventional bilevel positive airway pressure (BPAP) support in improving hypercarbia in a cohort of pediatric patients with nocturnal hypoventilation.

METHODS

Retrospective review of patient records at an established tertiary pediatric sleep laboratory over a 6-year period. Ventilatory and sleep study parameters from AVAPS and conventional BPAP titration studies were compared. AVAPS was used only if hypoventilation was not controlled using conventional BPAP. Inspiratory pressures, tidal volumes, and adherence were downloaded on final titrated ventilatory settings. Comparisons were made using paired t test.

RESULTS

A total of 19 patients (11 boys, 8 girls; median age 10.5 years, range 1 to 20 years) were identified. Diagnoses included neuromuscular disease (n = 9), obstructive hypoventilation (n = 5), parenchymal lung disease (n = 4), and congenital central hypoventilation syndrome (n = 2). AVAPS demonstrated significant improvement in peak (P = .009) and mean (P = .001). Transcutaneous CO₂ parameters compared to conventional bilevel. Oxygenation on AVAPS showed positive trend but did not reach statistical significance. AVAPS delivered higher tidal volumes (P = .04) using similar pressures. There was no statistically significant difference in obstructive apnea-hypopnea index, respiratory arousal index, sleep efficiency, and adherence between AVAPS and conventional BPAP.

CONCLUSIONS

AVAPS was an effective alternative to conventional BPAP in improving hypercarbia in our selective cohort of pediatric patients. Prospective, longitudinal studies are needed to evaluate the benefits of AVAPS feature in the pediatric population.

Predictors of longitudinal outcomes for children using long-term noninvasive ventilation

BACKGROUND

Noninvasive ventilation (NIV) is a first-line therapy for sleep-related breathing disorders and chronic respiratory insufficiency. Evidence about predictors that may impact long-term NIV outcomes, however, is scarce. The aim of this study is to determine demographic, clinical, and technology-related predictors of long-term NIV outcomes.

METHODS

A 10-year multicentred retrospective review of children started on long-term continuous or bilevel positive airway pressure (CPAP or BPAP) in Alberta. Demographic, technology-related, and longitudinal clinical data were collected. Long-term outcomes examined included ongoing NIV use, discontinuation due to improvement in underlying conditions, switch to invasive mechanical ventilation (IMV) or death, patient/family therapy declination, transfer of services, and hospital admissions.

RESULTS

A total of 622 children were included. Both younger age and CPAP use predicted higher likelihood for NIV discontinuation due to improvement in underlying conditions (p < .05 and p < .01). Children with upper airway disorders or bronchopulmonary dysplasia were less likely to continue NIV (p < .05), while presence of central nervous system disorders had a higher likelihood of hospitalizations (p < .01). The presence of obesity/metabolic syndrome and early NIV-associated complications predicted higher risk for NIV declination (p < .05). Children with more comorbidities or use of additional therapies required more hospitalizations (p < .05 and p < .01) and the latter also predicted higher risk for being switched to IMV or death (p < .001).

CONCLUSIONS

Demographic, clinical data, and NIV type impact long-term NIV outcomes and need to be considered during initial discussions about therapy expectations with families. Knowledge of factors that may impact long-term NIV outcomes might help to better monitor at-risk patients and minimize adverse outcomes.

Health-related quality of life and developmental outcome of children on home mechanical ventilation in a developing country: A cross-sectional study

BACKGROUND

Provision of home mechanical ventilation (HMV) to children with chronic respiratory insufficiency enhances growth and quality of life. The hypothesis was that health-related quality of life (HRQoL) and the development of these children were poorer than in healthy children.

OBJECTIVES

To determine the HRQoL and developmental outcome of children on HMV.

METHODS

This cross-sectional study used the TNO-AZL Preschool children's Quality Of Life (TAPQOL; <5 years old) and Health Utilities Index (HUI) 2/3 (≥5 years old) to assess the quality of life and the Schedule of Growing Skills-II to assess development. Instruments were used on children currently or previously on HMV (≥3 months) and compared with age and sex-matched controls.

RESULTS

Sixty-five patients and 130 controls were recruited. Patients' median (interquartile range) age was 3.12 (1.65, 5.81) years. Patients had significantly lower TAPQOL scores in the domains of lung, liveliness, positive mood, social functioning, motor functioning, and communication, and lower HUI 2/3 scores in hearing, sensation, pain, speech, mobility, ambulatory, dexterity, and self-care domains. The developmental outcome of patients was poorer in all domains. However, patients had fewer behavioral problems. Those with respiratory tract disease and without comorbidities had better HRQoL and developmental scores. Having a parent as the primary caregiver was associated with better speech and language skills.

CONCLUSIONS

HRQoL and the developmental outcome are lower in children on HMV compared to controls. Children with respiratory tract disease and without comorbidities have a better outcome. Parents play a crucial role in the acquisition of speech.

Long-Term Non-invasive Ventilation in Children: Current Use, Indications, and Contraindications

This review focuses on the delivery of non-invasive ventilation-i.e., intermittent positive-pressure ventilation-in children lasting more than 3 months. Several recent reviews have brought to light a dramatic escalation in the use of long-term non-invasive ventilation in children over the last 30 years. This is due both to the growing number of children receiving care for complex and severe diseases necessitating respiratory support and to the availability of LT-NIV equipment that can be used at home. While significant gaps in availability persist for smaller children and especially infants, home LT-NIV for children with chronic respiratory insufficiency has improved their quality of life and decreased the overall cost of care. While long-term NIV is usually delivered during sleep, it can also be delivered 24 h a day in selected patients. Close collaboration between the hospital complex-care team, the home LT-NIV program, and family caregivers is of the utmost importance for successful home LT-NIV. Long-term NIV is indicated for respiratory disorders responsible for chronic alveolar hypoventilation, with the aim to increase life expectancy and maximize quality of life. LT-NIV is considered for conditions that affect respiratory-muscle performance (alterations in central respiratory drive or neuromuscular function) and/or impose an excessive respiratory load (airway obstruction, lung disease, or chest-wall anomalies). Relative contraindications for LT-NIV include the inability of the local medical infrastructure to support home LT-NIV and poor motivation or inability of the patient/caregivers to cooperate or understand recommendations. Anatomic abnormalities that interfere with interface fitting, inability to protect the lower airways due to excessive airway secretions and/or severely impaired swallowing, or failure of LT-NIV to support respiration can lead to considering invasive ventilation via tracheostomy. Of note, providing home LT-NIV during the COVID 19 pandemic has become more challenging. This is due both to the disruption of medical systems and the fear of contaminating care providers and family with aerosols generated by a patient positive for SARS-CoV-2 during NIV. Delay in initiating LT-NIV, decreased frequency of home visits by the home ventilation program, and decreased availability of polysomnography and oximetry/transcutaneous PCO2 monitoring are observed. Teleconsultations and telemonitoring are being developed to mitigate these challenges.

Liberation and mortality outcomes in pediatric long-term ventilation: A qualitative systematic review

OBJECTIVE

To provide a systematic review of liberation from positive pressure ventilation and mortality of children with chronic respiratory failure who used long-term invasive and noninvasive ventilation (LTV).

METHODS

Papers published from 1980 to 2018 were identified using Pubmed MEDLINE, Ovid MEDLINE, Embase, and Cochrane databases. Search results were limited to English-language papers with (a) patients less than 22 years at initiation, (b) patients who used invasive ventilation (IV) via tracheostomy or noninvasive ventilation (NIV), and (c) data on mortality or liberation from LTV. Data were presented using descriptive statistics; changes in outcomes over time were explored using linear regression. Follow-up variability, cohort heterogeneity, and insufficient data precluded combining data to estimate incidences or rates.

RESULTS

One hundred and thirty papers with 12 704 patients were included. The median number of patients was 37 (interquartile range [IQR] 17-74, range 6-3802). Twenty-five percent of patients were initiated on IV; 75% on NIV. The maximum follow-up ranged from 0.5 to 31.8 years (median 8.8 years). The median proportion of patients liberated in these papers was 3% (IQR 0%-21%). The median proportion of mortality was 18% (IQR 8%-27%). Proportions of liberation and mortality did not significantly change over time. Progression of underlying disease (44%), respiratory illness (19%), and LTV accident (11%) were the most common causes of death.

CONCLUSIONS

These papers collectively show most patients survive for many years using LTV; in many subgroups, death is a more common outcome than liberation. However, the limitations of these papers preclude robust prognostication.

Non-invasive Ventilation and CPAP Failure in Children and Indications for Invasive Ventilation

Non-invasive ventilation (NIV) and continuous positive airway pressure (CPAP) are effective treatments for children with severe sleep disordered breathing (SBD). However, some patients may present too severe SDB that do not respond to NIV/CPAP or insufficient compliance to treatment. A careful revaluation of the interface and of ventilator settings should be performed before considering alternative treatments. In patients with obstructive sleep apnea (OSA), alternatives to CPAP/NIV rely on the underlying disease. Ear-nose-throat (ENT) surgery such as adeno-tonsillectomy (AT), turbinectomy or supraglottoplasty represent an effective treatment in selected patients before starting CPAP/NIV and should be reconsidered in case of CPAP failure. Rapid maxillary expansion (RME) is restricted to children with OSA and a narrow palate who have little adenotonsillar tissue, or for those with residual OSA after AT. Weight loss is the first line therapy for obese children with OSA before starting CPAP and should remain a priority in the long-term. Selected patients may benefit from maxillo-facial surgery such as mandibular distraction osteogenesis (MDO) or from neurosurgery procedures like fronto-facial monobloc advancement. Nasopharyngeal airway (NPA) or high flow nasal cannula (HFNC) may constitute efficient alternatives to CPAP in selected patients. Hypoglossal nerve stimulation has been proposed in children with Down syndrome not tolerant to CPAP. Ultimately, tracheostomy represents the unique alternative in case of failure of all the above-mentioned treatments. All these treatments require a multidisciplinary approach with a personalized treatment tailored on the different diseases and sites of obstruction. In patients with neuromuscular, neurological or lung disorders, non-invasive management in case of NIV failure is more challenging. Diaphragmatic pacing has been proposed for some patients with central congenital hypoventilation syndrome (CCHS) or neurological disorders, however its experience in children is limited. Finally, invasive ventilation via tracheotomy represents again the ultimate alternative for children with severe disease and little or no ventilatory autonomy. However, ethical considerations weighting the efficacy against the burden of this treatment should be discussed before choosing this last option.

Pediatric Home Mechanical Ventilation in Korea: the Present Situation and Future Strategy

BACKGROUND

The number of children using home mechanical ventilation (HMV) has increased markedly in Europe and North America, but little is known about the situation in Korea. We described the clinical characteristics of children using HMV and investigated the current situation of HMV utilization in children.

METHODS

Data on HMV prescriptions in year 2016 for children under the age of 19 was retrieved from the National Health Insurance Service for nationwide information. For more detailed information, data from year 2016 to 2018 was also retrieved from a tertiary center, Severance Children's Hospital.

RESULTS

Nationwide, 416 children were prescribed with HMV in 2016, with an estimated prevalence of 4.4 per 100,000 children, of which 64.2% were male and mean age was 6-year-old. The estimated number of patients using invasive ventilators via tracheostomy was 202 (49%). Neuromuscular diseases were the most frequent cause (217; 52%), followed by central nervous system diseases (142; 34%), and cardiopulmonary diseases (57; 14%). In the tertiary center, a total of 62 children were prescribed with HMV (19 [31%] with non-invasive ventilation; 43 [69%] with invasive ventilation]. The number of children with HMV increased from 11 in 2016 to 29 in 2018. The mean age for initiation of HMV was 3.1 years and male patients comprised 65%. The most frequent diagnostic reason for HMV was central nervous system diseases (68%), followed by cardiopulmonary diseases (19%) and neuromuscular diseases (13%). Five patients died during the study period and five patients weaned from HMV.

CONCLUSION

This study provides insights on the present situation of HMV utilization in Korean children.

Longitudinal changes in clinical characteristics and outcomes for children using long-term non-invasive ventilation

Objectives

To describe longitudinal trends in long-term non-invasive ventilation (NIV) use in children including changes in clinical characteristics, NIV technology, and outcomes.

Methods

This was a multicenter retrospective cohort of all children started on long-term NIV from 2005 to 2014. All children 0 to 18 years who used NIV continuously for at least 3 months were included. Measures and main outcomes were: 1) Number of children starting NIV; 2) primary medical condition; 3) medical complexity defined by number of comorbidities, surgeries and additional technologies; 4) severity of sleep disordered breathing measured by diagnostic polysomnography; 5) NIV technology and use; 6) reasons for NIV discontinuation including mortality. Data were divided into equal time periods for analysis.

Results

A total of 622 children were included in the study. Median age at NIV initiation was 7.8 years (range 0–18 years). NIV incidence and prevalence increased five and three-fold over the 10-year period. More children with neurological and cardio-respiratory conditions started NIV over time, from 13% (95%CI, 8%-20%) and 6% (95%CI, 3%-10%) respectively in 2005–2008 to 23% (95%CI, 18%-28%) and 9% (95%CI, 6%-14%, p = 0.008) in 2011–2014. Medical complexity and severity of the sleep-disordered breathing did not change over time. Overall, survival was 95%; mortality rates, however, rose from 3.4 cases (95% CI, 0.5–24.3) to 142.1 (95% CI 80.7–250.3, p<0.001) per 1000 children-years between 2005–2008 and 2011–2014. Mortality rates differed by diagnostic category, with higher rates in children with neurological and cardio-respiratory conditions.

Conclusions

As demonstrated in other centers, there was a significant increase in NIV prevalence and incidence rate. There was no increase in medical complexity or severity of the breathing abnormalities of children receiving long-term NIV over time. The mortality rate increased over time, maybe attributable to increased use of NIV for children with neurological and cardio-respiratory conditions.

Caregiver knowledge and skills to safely care for pediatric tracheostomy ventilation at home

OBJECTIVE

Caregivers of children using home mechanical ventilation (HMV) via tracheostomy require appropriate knowledge and skills. Existing training curricula are locally developed and content variable. We sought to develop a competency checklist to inform initial training and subsequent assessment of knowledge and skills of family caregivers.

METHODS

We used a 2-step process. Candidate items were generated by synthesis of a scoping review, existing checklists, with additional items suggested by an eight member inter-professional group representing pediatric HMV programs across Canada. Following removal of duplicate items, we conducted a three-round Delphi to gain consensus on items for the KidsVent Checklist.

RESULTS

The scoping review and checklists from five HMV programs identified 18 domains and 172 items; one additional domain and 83 additional items were identified by our expert group who also classified domains as mandatory or optional. We recruited 95 clinicians representing 12 Canadian paediatric HMV programs to participate in Delphi round 1 (response rate 72%; 84%, and 100% for subsequent rounds). Importance rating of the 255 items reduced them to 246 items. In the final checklist, the 19 domains comprised 14 mandatory (189 mandatory items) and 5 optional domains (57 optional items).

CONCLUSIONS

We have developed the KidsVent checklist using rigorous consensus building methods, informed by participants with diverse geographic and inter-professional representation. This checklist represents knowledge and skills required to safely care for children using tracheostomy ventilation at home. Further study is required to explore the impact of this checklist on outcomes of this growing group of technology-dependent children.

Quality of life in home-ventilated children and their families

HMV (home mechanical ventilation) in children has increased over the last years. The aim of the study was to assess perceived quality of life (QOL) of these children and their families as well as the problems they face in their daily life.We performed a multicentric cross-sectional study using a semi-structured interview about the impact of HMV on families and an evaluation questionnaire about perceived QOL by the patient and their families (pediatric quality of life questionnaire (PedsQL4.0)). We studied 41 subjects (mean age 8.2 years). Global scores in PedsQL questionnaire for subjects (median 61.4), and their parents (median 52.2) were below those of healthy children. 24.4% received medical follow-up at home and 71.8% attended school. Mothers were the main caregivers (75.6%), 48.8% of which were fully dedicated to the care of their child. 71.1% consider economic and healthcare resources insufficient. All families were satisfied with the care they provide to their children, even though it was considered emotionally overwhelming (65.9%). Marital conflict and neglect of siblings appeared in 42.1 and 36% of families, respectively.

CONCLUSIONS

Perceived QOL by children with HMV and their families is lower than that of healthy children. Parents are happy to care for their children at home, even though it negatively affects family life. What is Known: • The use of home mechanical ventilation (HMV) in children has increased over the last years. • Normal family functioning is usually disrupted by HMV. What is New: • The aim of HMV is to provide a lifestyle similar to that of healthy children, but perceived quality of life by these patients and their parents is low. • Most of the families caring for children on HMV agree that support and resources provided by national health institutions is insufficient.

Long term continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) in children: Initiation criteria in real life

INTRODUCTION

Long term noninvasive continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) are increasingly used in children but limited information is available on the criteria and conditions leading to the initiation of these treatments. The aim of the study is to describe the objective overnight respiratory parameters and clinical situations that led to the initiation of CPAP/NIV in a pediatric NIV unit.

MATERIAL AND METHODS

Retrospective analysis of the data of all the children discharged on home CPAP/NIV over a 1 year period.

RESULTS

Seventy-six patients were started on CPAP (n = 64) or NIV (n = 12). CPAP/NIV was initiated because of CPAP/NIV weaning failure (Acute group) in 15 patients. None of these patients had an overnight gas exchange or sleep study before CPAP/NIV initiation. In 18 patients, CPAP/NIV was initiated on abnormal nocturnal gas exchange alone (Subacute group). These patients had a median of three of the following five overnight gas exchange abnormalities: minimal pulse oximetry (SpO2 ) <90%, maximal transcutaneous carbon dioxide (PtcCO2 ) >50 mmHg, time spent with SpO2 <90% or PtcCO2 >50 mmHg ≥2% of recording time, oxygen desaturation index >1.4/hr. In the last 43 patients, CPAP/NIV was initiated after an abnormal sleep study (Chronic group) on a mean of four of the aforementioned criteria and an apnea-hypopnea index >10/hr.

CONCLUSION

In clinical practice, CPAP/NIV was initiated in an acute, subacute and chronic setting with most patients having an association of several abnormal gas exchange or sleep study parameters. Future studies should evaluate the effectiveness and benefits of CPAP/NIV according to the clinical situation and initiation criteria.

Parental Perceptions of Quality of Life in Children on Long-Term Ventilation at Home as Compared to Enterostomy Tubes

Objective

Health related quality of life (HRQL) of children using medical technology at home is largely unknown. Our aim was to examine the HRQL in children on long-term ventilation at home (LTHV) in comparison to a cohort using an enterostomy tube.

Study Design

Participants were divided into three groups: 1) LTHV without an enterostomy tube (LTHV cohort); 2) Enterostomy tube (GT cohort); 3) LTHV with an enterostomy tube (LTHV+GT cohort). Caregivers of children ≥ 5 years and followed at SickKids, Toronto, Canada, completed three questionnaires: Health Utilities Index 2/3 (HUI2/3), Caregiver Priorities Caregiver Health Index (CPCHILD), and the Paediatric Quality of Life Inventory (PedsQL). The primary outcome was the difference in utility (HUI2/3) scores between the cohorts.

Results

One hundred and nineteen children were enrolled; 47 in the LTHV cohort, 44 in the GT cohort, and 28 in the LTHV+GT cohort. In univariate analysis, HUI2 mean (SE) scores were lowest for the GT cohort, 0.4 (0.04) followed by the LTHV+GT, 0.42 (0.05) and then the LTHV cohort, 0.7 (0.04), p = 0.001. A similar trend was seen for the HUI3 mean (SE) scores: GT cohort, 0.1 (0.06), followed by the LTHV +GT cohort, 0.2 (0.08) and then the LTHV cohort, 0.5 (0.06), p = 0.0001. Technology cohort, nursing hours and the severity of health care needs predicted HRQL as measured by the HUI2/3.

Conclusion

The HRQL of these children is low. Children on LTHV had higher HRQL than children using enterostomy tubes. Further work is needed to identify modifiable factors that can improve HRQL.

How long does it take to initiate a child on long-term invasive ventilation? Results from a Canadian pediatric home ventilation program

OBJECTIVE

To assess the length of stay required to initiate long-term invasive ventilation at the authors' institution, which would inform future interventional strategies to streamline the in-hospital stay for these families.

METHODS

A retrospective chart review of children initiated on invasive long-term ventilation via tracheostomy at the authors' acute care centre between January 2005 and December 2013 was performed.

RESULTS

Thirty-five children were initiated on long-term invasive ventilation via tracheostomy at the acute care hospital; 19 (54%) were male. The median age at time of admission was 0.52 years (interquartile range [IQR] 0.06 to 9.58 years) . Musculoskeletal disease (n=11 [31%]) was the most common reason for tracheostomy insertion. Two children died during the hospital admission. Fifteen children were discharged home directly from the acute care hospital and 18 were moved to the rehabilitation hospital. Six are current inpatients of the rehabilitation centre and were never discharged home. Combining the length of stay at the acute care and rehabilitation hospitals for the entire cohort, the median length of stay was 162.0 days (IQR 98.0 to 275.0 days) and 97.0 days (IQR 69.0 to 210.0 days), respectively, from the time of tracheostomy insertion.

CONCLUSIONS

The median length of stay from the initiation of invasive long-term ventilation to discharge home from the rehabilitation hospital was somewhat long compared with other ventilation programs worldwide. Additionally, approximately 20% of the cohort never transitioned home. There is a timely need to benchmark across the country and internationally, to identify and implement strategies for cohesive, coordinated care for these children to decrease overall length of stay.

A comparison of invasive and noninvasive ventilation in children less than 1 year of age: A long-term follow-up study

BACKGROUND

We report on the long-term survival of children initiated on invasive and noninvasive positive pressure ventilation (NiPPV) before the age of 1 to assess the safety and efficacy of long-term ventilation at home.

METHODS

A chart review was performed of children initiated on long-term home mechanical ventilation (LTHV) before the age of 1 year, at The Hospital for Sick Children (SickKids), Canada, between January 1991 and April 2014.

RESULTS

We report on 51 children. Twenty-five children (49%) received NiPPV and 26 (51%) received invasive mechanical ventilation via tracheostomy (IMV). There was one NiPPV initiation between 1991 and 2001, the rest were in subsequent years. Most children had a "musculoskeletal disorder" in the NiPPV cohort, n = 14 (56%) and a "central nervous system" disorder in the IMV cohort, n = 13 (50%). The pCO2 improved with the initiation of NiPPV, P = < 0.0001. Of the 25 subjects initiated on NiPPV, eight (32%) are currently being followed as compared to 22 (84%) in the IMV cohort. Seven (28%) of the NiPPV group were weaned off ventilation as compared to three (11.5%) in the IMV cohort. There were two NiPPV treatment failures. There were more deaths in the NiPPV cohort: eight (32%) versus two (7.6%) in the IMV cohort. Four of the deaths in the NiPPV cohort were in children in whom a palliative approach was taken. None were due to NiPPV technical failure.

CONCLUSIONS

Based on this long-term follow-up study, NiPPV use in infants appears to be a viable long-term ventilation strategy.

Long-term non-invasive ventilation therapies in children: a scoping review protocol

INTRODUCTION

Non-invasive ventilation (NIV) in children has become an increasingly common modality of breathing support where pressure support is delivered through a mask interface or less commonly through other non-invasive interfaces. At this time, NIV is considered a first-line option for ventilatory support of chronic respiratory insufficiency associated with a range of respiratory and sleep disorders. Previous reviews on the effectiveness, complications and adherence to NIV treatment have lacked systematic methods. The purpose of this scoping review is to provide an overview of the evidence for the use of long-term NIV in children.

METHODS AND ANALYSIS

We will use previously established scoping methodology. Ten electronic databases will be searched to identify studies in children using NIV for longer than 3 months outside an intensive care setting. Grey literature search will include conference proceedings, thesis and dissertations, unpublished trials, reports from regulatory agencies and manufacturers. Two reviewers will independently screen titles and abstracts for inclusion, followed by full-text screening of potentially relevant articles to determine final inclusion. Data synthesis will be performed at three levels: (1) an analysis of the number, publication type, publication year, and country of publication of the studies; (2) a summary of the study designs, outcomes measures used; (3) a thematic analysis of included studies by subgroups.

ETHICS AND DISSEMINATION

This study will provide a wide and rigorous overview of the evidence on the use of long-term NIV in children and provide critical information for healthcare professionals and policymakers to better care for this group of children. We will disseminate our findings through conference proceedings and publications, and evaluate the results for further systematic reviews and meta-analyses.

Long-term ventilation in children: ten years later

INTRODUCTION

Home mechanical ventilation (HMV) represents a treatment option for patients with chronic respiratory failure and has changed prognosis and survival of many disorders in children. The aim of this study was to characterize a group of children on long-term mechanical ventilation (LTMV) for a period longer than 10 years.

METHODS

A retrospective analysis was carried out including patients on LTMV for more than 10 years (LTMV-10) in a tertiary pediatric hospital.

STATISTICAL ANALYSIS

PASW Statistics 18(®).

RESULTS

Thirty-one children (61% female) belong to the LTMV-10 group. Median age at the beginning of ventilatory support was 3 years (birth to 13 years). Main indications for assisted ventilation were neuromuscular disease (n=12, 39%), metabolic disease (n=7, 23%) and central hypoventilation (n=6, 19%). Volume ventilation was used in 2 children, and positive pressure ventilation in the others, mainly bilevel positive airway pressure (n=25, 81%). Invasive ventilation via tracheostomy was used since the beginning in four cases, and subsequently in two other children. The mean time of ventilatory support was 146 months and the maximum was 219 months. Respiratory morbidity was the most frequent cause of hospitalization and the annual rate of such episodes was 0.17 per child. Global mortality rate was 19%.

CONCLUSIONS

HMV programs provide necessary and safe assistance for children with severe chronic respiratory failure. As shown in our series, it is possible to be kept on this respiratory support modality for long periods with good compliance and a small number of hospitalizations.

Pediatric long-term home mechanical ventilation: twenty years of follow-up from one Canadian center

BACKGROUND

Canadian longitudinal data from a pediatric domiciliary long-term mechanical ventilation (LTMV) program is lacking.

OBJECTIVE

Our aim was to report on the clinical characteristics and trends of children followed in one of Canada's pediatric home ventilation programs over the past 20 years.

METHODS

A retrospective chart review was conducted on patients receiving long-term domociliary mechanical ventilation between January 1, 1991 and December 31, 2011 in a single center. Domiciliary long-term mechanical ventilation was defined as the daily use of invasive mechanical ventilation (IMV) or noninvasive positive pressure ventilation (NiPPV) for at least 3 months, in the users' home or in a long-term residential facility.

RESULTS

Between 1991 and 2011, a total of 379 children were identified (313 [83%] with noninvasive ventilation). The median age at initiation was 9.6 years (interquartile range [IQR] 2.9-13.9), the median duration of ventilation was 2.2 years (IQR 0.8-4.9) and 53% were male. Ninety-nine percent of children were cared for at home. The reason for ventilation was "musculoskeletal" in origin for the majority of children. The number of children receiving long-term mechanical ventilation at home increased from 2 in 1991 to 156 children as of December 2011. There was a twofold increase in the number of invasive ventilation initiations in the second 10 years, n = 45 (2001-2011) as compared to the first 10 years, n = 21 (1991-2000). However, there was more than a fivefold increase in the number of noninvasive initiations in the first 10 years, n = 50 (1991-2000) as compared to the second 10 years, n = 263 (2001-2011). The largest growth was in the 13-18 years age group. There were 55 (15%) mortalities over the study period.

CONCLUSIONS

In summary, our 20-year retrospective study has shown that there has been an exponential growth in the number of children receiving domiciliary LTMV with the majority of children having favorable outcomes. Our study represents a step towards developing a Canadian registry to design and implement programmatic change for this medically complex population to ensure best practice for these children as well as their families.

Outcomes of children treated with tracheostomy and positive-pressure ventilation at home

BACKGROUND

Long-term outcomes for children who survive on tracheostomy and positive-pressure ventilation (TPPV) at home are not well known.

METHODS

A retrospective review of 20 years of clinical data at a single institution was performed. Outcome measures included 5-year survival, decannulation rate, and neurocognition.

RESULTS

A total of 91 children were categorized under neuromotor dysfunction (52%), chronic lung disease (29%), and congenital anomalies (20%). The 5-year survival rates for these categories were 89% (95% confidence interval [CI] = 80%-99%), 76% (95% CI = 57%-100%), and 94% (95% CI = 83%-100%), respectively. Overall, the 5-year decannulation rate was 25% (95% CI = 14%-35%), with children with chronic lung disease having the highest rate (51%). It was found that 14% were extremely delayed in neurocognition.

CONCLUSION

Most children on TPPV at home survive beyond 5 years, and a significant number are decannulated. Primary care physicians and communities should be prepared to accommodate the increasing number of children on TPPV at home.

Thirty years of home mechanical ventilation in children: escalating need for pediatric intensive care beds

Purpose

To describe trends in pediatric home mechanical ventilation (HMV) and their impact on the use of pediatric intensive care unit (PICU) beds.

Methods

Review of all children who had started HMV in a single center for HMV.

Results

Between 1979 and 2009, HMV was started in 197 patients [100 (51 %) with invasive and 97 with noninvasive ventilation], with a median age of 14.7 (range 0.5–17.9) years. Most patients (77 %) were males with a neuromuscular disorder (66 %). The number of children receiving HMV increased from 8 in the 1979–1988 period to 122 in the 1999–2008 period. This increase occurred foremost in patients aged 0–5 years and was accompanied by a sharp rise in the use of PICU beds. In 150 patients (76 %), HMV was initiated on an ICU with a total of 12,440 admission days, of which 10,385 days (83 %) could be attributed to 67 patients who started non-electively with invasive HMV. Of the latter, 52 patients had been admitted to a PICU with a total of 9,335 admission days. At the end of the study, 134 patients (68 %) were still being ventilated, 43 patients (22 %) had died, 11 patients (6 %) were weaned from HMV, 4 patients (2 %) did not want to continue HMV and 5 patients (3 %) were lost to follow-up.

Conclusions

Over time, there was an impressive increase in the application of HMV in children. This increase was most obvious in the youngest age group with invasive HMV, and these children had very long stays in the PICU.

Increasing prevalence of domiciliary ventilation: changes in service demand and provision in the South West of the UK

We examine the incidence and prevalence of domiciliary ventilation in the South West region of the UK, assess trends over 15 years, and describe patient outcome. We conducted a retrospective review of all patients below 18 years receiving domiciliary ventilation in the South West region of the UK between January 1994 and August 2009. Children who received long-term ventilation solely in hospital were excluded from the study. Information was obtained from a locally held database, medical notes, and hospital administration systems. One hundred-six patients were identified. Prevalence has increased since 1994 from 0.2 to 6.7 per 100,000 children. The incidence of both invasive and non-invasive ventilations has increased with a trend towards more non-invasive therapy. The commonest underlying disorders were airway pathology (37 patients), neuromuscular disease (34 patients), and central congenital hypoventilation disorder (17 patients). Sixty-seven patients had significant co-morbidities. Of 38 non-current patients, 19 were transferred to adult ventilation services, 11 died, and 6 were successfully weaned from ventilatory support. In conclusion, there has been a 30-fold increase in the prevalence of paediatric domiciliary ventilation, in the South West region of the UK, since 1994. Co-morbidities are common. Very few children discontinue long-term ventilation, and increasing numbers of ventilated children are transferred to adult services.

Long-term home ventilation of children in Italy: a national survey

BACKGROUND

Improved technology, as well as professional and parental awareness, enable many ventilator-dependent children to live at home. However, the profile of this growing population, the quality and adequacy of home care, and patients' needs still require thorough assessment.

OBJECTIVES

To define the characteristics of Italian children receiving long-term home mechanical ventilation (HMV) in Italy.

METHODS

A detailed questionnaire was sent to 302 National Health Service hospitals potentially involved in the care of HVM in children (aged <17 years). Information was collected on patient characteristics, type of ventilation, and home respiratory care.

RESULTS

A total of 362 HMV children was identified. The prevalence was 4.2 per 100,000 (95% CI: 3.8-4.6), median age was 8 years (interquartile range 4-14), median age at starting mechanical ventilation was 4 years (1-11), and 56% were male. The most frequent diagnostic categories were neuromuscular disorders (49%), lung and upper respiratory tract diseases (18%), hypoxic (ischemic) encephalopathy (13%), and abnormal ventilation control (12%). Medical professionals with nurses (for 62% of children) and physiotherapists (20%) participated in the patients' discharge from hospital, though parents were the primary care giver, and in 47% of cases, the sole care giver. Invasive ventilation was used in 41% and was significantly related to young age, southern regional residence, longer time spent under mechanical ventilation, neuromuscular disorders, or hypoxic (ischemic) encephalopathy.

CONCLUSIONS

Care and technical assistance of long-term HMV children need assessment, planning, and resources. A wide variability in pattern of HMV was found throughout Italy. An Italian national ventilation program, as well as a national registry, could be useful in improving the care of these often critically ill children.

A home respiratory support programme for children by parents and layperson carers

AIM

To describe a respiratory support programme for children at home by parents and layperson carers.

METHODS

Analysis of records of children with long-term mechanical respiratory support at home.

RESULTS

From 1979 to 2008 the programme managed 168 children (median age 7 years, range 3 weeks-19 years) with obstructive sleep apnoea (55, 32%), neuromuscular conditions (42, 25%), tracheo-bronchomalacia (23, 14%), kyphoscoliosis-cerebral palsy (20, 12%), acquired central hypoventilation (8, 5%), congenital central hypoventilation (7, 4%), chronic lung disease or pulmonary hypoplasia (8, 5%), traumatic quadriplegia (3, 2%) and tumour-related quadriplegia (2, 1%). One hundred and sixty-one (96%) were discharged: 73 (46%) remain in the programme; 27 (16%) transferred to adult services, 25 (15%) recovered and 36 (23%) died. Principal modes of therapy were mask continuous positive airway pressure (CPAP) 35%, mask bilevel positive airway pressure 30%, tracheostomy CPAP 20%, tracheostomy mechanical ventilation 8%, phrenic nerve pacing 3%, negative pressure chamber ventilation 2% and nasal tube CPAP 2%. Two unexpected deaths occurred at home: one from accidental tracheostomy decannulation and another unrelated to respiratory support. Average time in the programme was 3.3 years. Parents of 69 children were provided with trained carers. Successful discharge resulted from early recognition of potential to discharge, parental training, recruitment and training of carers, purchase of equipment and secure funding. Seven children were not discharged, two of whom died in the hospital and five are subject to discharge planning.

CONCLUSION

Respiratory support of children at home by trained parents and layperson carers is safe and efficient. All modes of respiratory support may be used.

Treatment alternatives for sleep-disordered breathing in the pediatric population

PURPOSE FOR REVIEW: Childhood sleep-disordered breathing (SDB) is associated with a myriad of health problems that underscore the need for early diagnosis and treatment. Children with SDB present with behavior problems, deficits of general intelligence, learning and memory deficits, evidence of brain neuronal injury, increased cardiovascular risk, and poor quality of life. Children are in a rapid state of cognitive development; therefore, alterations of health and brain function associated with SDB could permanently alter a child's social and economic potential, especially if the disorder is not recognized early in life or is treated inadequately.

RECENT FINDINGS

There is evidence that the majority of the problems associated with SDB improve with treatment. Treatment strategies are now being aimed at mechanisms underlying the disorder. There are multiple treatment options available to children; some are novel, with pending treatments on the horizon that may replace age-old therapies such as adenotonsillectomy or nasal positive pressure.

SUMMARY

It is imperative that healthcare workers actively seek out signs and symptoms of SDB in patients to improve early detection and treatment for prevention of long-term morbidity.

Hospital discharge of the high-risk neonate

This policy statement updates the guidelines on discharge of the high-risk neonate first published by the American Academy of Pediatrics in 1998. As with the earlier document, this statement is based, insofar as possible, on published, scientifically derived information. This updated statement incorporates new knowledge about risks and medical care of the high-risk neonate, the timing of discharge, and planning for care after discharge. It also refers to other American Academy of Pediatrics publications that are relevant to these issues. This statement draws on the previous classification of high-risk infants into 4 categories: (1) the preterm infant; (2) the infant with special health care needs or dependence on technology; (3) the infant at risk because of family issues; and (4) the infant with anticipated early death. The issues of deciding when discharge is appropriate, defining the specific needs for follow-up care, and the process of detailed discharge planning are addressed as they apply in general to all 4 categories; in addition, special attention is directed to the particular issues presented by the 4 individual categories. Recommendations are given to aid in deciding when discharge is appropriate and to ensure that all necessary care will be available and well coordinated after discharge. The need for individualized planning and physician judgment is emphasized.

Sleep studies frequently lead to changes in respiratory support in children

AIM

International guidelines recommend that children who are managed at home with mechanical respiratory support (RS) should have sleep studies performed every 6-12 months. This recommendation is based on expert opinion, with little evidence to support it. No studies have been undertaken to examine the utility of sleep studies in children on RS.

METHODS

A retrospective review of sleep studies performed over a 12-month period was undertaken at a New Zealand paediatric sleep medicine referral centre, to determine changes made to RS following sleep studies.

RESULTS

Sixty-one sleep studies were performed for assessment of RS in 45 children (27 boys; median age 8.3 years; range 0.4-18.6 years). Twenty-nine (64%) children were on continuous positive airway pressure, 14 (31%) on bi-level non-invasive ventilation, and two (4%) on tracheostomy ventilation. A change was made to RS settings after 66% of studies. No clinical parameters predicted which children would require a change in settings.

CONCLUSIONS

Although sleep studies are expensive and time-consuming, follow-up studies of children on RS provide important information for optimising management into the long term.
