Respiratory Care Considerations for Children with Medical Complexity

Paediatric sleep diagnostics in the 21st century: the era of "sleep-omics"?

Paediatric sleep diagnostics is performed using complex multichannel tests in specialised centres, limiting access and availability and resulting in delayed diagnosis and management. Such investigations are often challenging due to patient size (prematurity), tolerability, and compliance with "gold standard" equipment. Children with sensory/behavioural issues, at increased risk of sleep disordered breathing (SDB), often find standard diagnostic equipment difficult.SDB can have implications for a child both in terms of physical health and neurocognitive development. Potential sequelae of untreated SDB includes failure to thrive, cardiopulmonary disease, impaired learning and behavioural issues. Prompt and accurate diagnosis of SDB is important to facilitate early intervention and improve outcomes.The current gold-standard diagnostic test for SDB is polysomnography (PSG), which is expensive, requiring the interpretation of a highly specialised physiologist. PSG is not feasible in low-income countries or outwith specialist sleep centres. During the coronavirus disease 2019 pandemic, efforts were made to improve remote monitoring and diagnostics in paediatric sleep medicine, resulting in a paradigm shift in SDB technology with a focus on automated diagnosis harnessing artificial intelligence (AI). AI enables interrogation of large datasets, setting the scene for an era of "sleep-omics", characterising the endotypic and phenotypic bedrock of SDB by drawing on genetic, lifestyle and demographic information. The National Institute for Health and Care Excellence recently announced a programme for the development of automated home-testing devices for SDB. Scorer-independent scalable diagnostic approaches for paediatric SDB have potential to improve diagnostic accuracy, accessibility and patient tolerability; reduce health inequalities; and yield downstream economic and environmental benefits.

Post-acute day and night non-invasive respiratory intervention use and outcome: A brief report

OBJECTIVE

This study aimed to describe daytime and nighttime use and outcome of non-invasive respiratory intervention (NIRI) for infants born prematurely and for children with medical complexity (CMC) during a post-acute care hospital (PACH) admission.

METHODS

Thirty-eight initial PACH admissions (October 2018 through September 2020) for premature infants (< 1 year; n = 19) and CMC (> 1 year; n = 19) requiring NIRI during the day and/or at night were retrospectively examined. Measures included: 1) daytime and nighttime NIRI use by type (supplemental oxygen therapy via low-flow nasal cannula or positive airway pressure [PAP] via high-flow nasal cannula, continuous positive airway pressure, or biphasic positive airway pressure at admission and discharge) and 2) daytime and nighttime NIRI outcome-reduction, increase, or no change from admission to discharge.

RESULTS

For the total sample (n = 38), daytime vs nighttime NIRI use was significantly different (p < 0.001). At both admission and discharge, supplemental oxygen was the most common NIRI during the day, while PAP was most common at night. From admission to discharge, seven (18%) infants and children had a positive change (reduced NIRI) during the day, while nine (24%) had a positive change at night. At discharge, 11/38 (29%) infants and children required no daytime NIRI, while 4/38 (11%) required no day or night NIRI.

CONCLUSION

NIRI use differs between day and night at PACH admission and discharge for CMC. Reductions in NIRI were achieved during the day and at night from PACH admission to discharge for both infants born prematurely and for children with varied congenital, neurological, or cardiac diagnoses.

Polysomnography in hospitalized children: Characteristics and clinical practice at a single tertiary care center

BACKGROUND

Polysomnography (PSG) is the gold standard for the diagnosis of pediatric sleep-disordered breathing (SDB). However, the literature characterizing the indications for inpatient PSGs and the impact on clinical decision-making is limited.

OBJECTIVE

To determine the indications, results, and outcomes for children undergoing inpatient PSGs at our institution.

METHODS

We performed a retrospective review of children aged 0-18 years who underwent inpatient diagnostic PSGs between July 2018 and July 2021 at SickKids, Toronto, Canada. Baseline characteristics, indications, and management were reviewed and characterized by descriptive statistics.

RESULTS

Eighty-eight inpatient PSGs were performed in 75 children (male 62.7%). Median (interquartile range) age and body mass index z-score were 1.5 (0.2, 10.8) years and 0.27 (-1.58, 2.66), respectively. The most common indication for inpatient PSG was initiation and titration of ventilation (n = 34/75, 45.3%). Of the 75 children, 48 (64%) had multiple complex chronic conditions (CCCs). Sixty children (80%) underwent a baseline PSG for either the entire night or a portion of the night. Of these studies, 54 (90%) had clinically significant SDB of which isolated obstructive sleep apnea (OSA; 17/60, 28.3%) was the most common. The following management was undertaken for the 54 patients with SDB; respiratory technology (88.9%), surgical intervention (31.5%), positional therapy (1.9%), intranasal steroids (3.7%), and no further intervention (5.6%), respectively.

CONCLUSIONS

Our study highlights that inpatient PSG was an important diagnostic tool resulting in directed medical and surgical management. Future multicenter studies are needed to compare indications for inpatient PSGs across institutions to develop evidence-based clinical practice guidelines.

Examining the Role of Sublingual Atropine for the Treatment of Sialorrhea in Patients with Neurodevelopmental Disabilities: A Retrospective Review

Sialorrhea is common in children with neurodevelopmental disabilities (NDD) and is reported in >40% of children with cerebral palsy (CP). It causes a range of complications, including significant respiratory morbidity. This single-center retrospective chart review aims to document sublingual atropine (SLA) utilization to guide further study in establishing its role in secretion management for children with NDD. A chart review was completed for patients with NDD ≤ 22 years of age treated with SLA at a free-standing children's hospital between 1 January 2016 and 1 June 2021. Descriptive statistics were generated to summarize findings. In total, 190 patients were identified, of which 178 met inclusion criteria. The average starting dose for SLA was 1.5 mg/day, or 0.09 mg/kg/day when adjusted for patient weight. Eighty-nine (50%) patients were prescribed SLA first line for secretion management while 85 (48%) patients tried glycopyrrolate prior to SLA. SLA was used after salivary Botox, ablation, and/or surgery in 16 (9%) patients. This study investigates SLA as a potential pharmacologic agent to treat sialorrhea in children with NDD. We identify a range of prescribing patterns regarding dosing, schedule, and place in therapy, highlighting the need for further evidence to support and guide its safe and efficacious use.

Exploring the experience of family caregivers of children with medical complexity during COVID-19: a qualitative study

BACKGROUND AND OBJECTIVES

Children with medical complexity have been disproportionately impacted by the COVID-19 pandemic and the associated changes in healthcare delivery. The primary objective of this study was to gain a thorough understanding of the lived experiences of family caregivers of children with medical complexity during the pandemic.

METHODS

We conducted semi-structured interviews with family caregivers of children with medical complexity from a tertiary pediatric hospital. Interview questions focused on the aspects of caregiving for children with medical complexity, impact on caregiver mental and physical well-being, changes to daily life secondary to the pandemic, and experiences receiving care in the healthcare system. Interviews were conducted until thematic saturation was achieved. Interviews were audio recorded, deidentified, transcribed verbatim, coded and analyzed using content analysis.

RESULTS

Twelve semi-structured interviews were conducted. The interviews revealed three major themes and several associated subthemes: (1) experiences with the healthcare system amid the pandemic (lack of access to healthcare services and increased hospital restrictions, negative clinical interactions and communication breakdowns, virtual care use); (2) common challenges during the pandemic (financial strain, balancing multiple roles, inadequate homecare nursing); and (3) the pandemic's impact on family caregiver well-being (mental toll, physical toll).

CONCLUSIONS

Family caregivers of children with medical complexity experienced mental and physical burden due to the intense nature of their caregiving responsibilities that were exacerbated during the pandemic. Our results highlight key priorities for the development of effective interventions to support family caregivers and their children.

Long-Term Ventilation in Children with Medical Complexity: A Challenging Issue

Children with medical complexity (CMCs) represent a subgroup of children who may have congenital or acquired multisystemic disease. CMCs are frequently predisposed to respiratory problems and often require long-term mechanical ventilation (LTMV). The indications for LTMV in CMCs are increasing, but gathering evidence about indications, titration, and monitoring is currently the most difficult challenge due to the absence of validated data. The aim of this review was to examine the clinical indications and ethical considerations for the initiation, continuation, or withdrawal of LTMV among CMCs. The decision to initiate long-term ventilation should always be based on clinical and ethical considerations and should be shared with the parents.

Respiratory Care of Big Data Communication to Prevent Respiratory Tract Infection Nursing Analysis of Patients with Heart Failure

Heart failure is the final stage of the development of heart disease, with a high mortality and disability rate. It poses a serious threat to human health and brings tremendous pressure to human society. Preventing respiratory infections in patients with heart failure is also the first priority of care. This article is aimed at studying the nursing analysis of respiratory tract care based on big data exchanges to prevent respiratory tract infections in patients with heart failure. This article uses benchmark and sample collection. Studies have shown that for Pseudomonas aeruginosa, its resistance to ampicillin, amoxicillin/clavulanic acid, cefazolin, cefuroxime, ceftriaxone, cefotaxime, and cefoxitin has reached more than 80%. It is also suitable for piperacillin, ticarcillin/clavulanic acid, piperacillin/tazobactam, cefepime, aztreonam, gentamicin, tobramycin, ciprofloxacin, and levofloxacin. The resistance rate of stars is within 10%-30%. These antibiotics are effective and can be used for clinical treatment. The drug resistance rates of ceftazidime, imipenem, meropenem, and amikacin were all lower than 10%, and the drug resistance rates of ceftazidime and imipenem were much lower than those reported in the 2016 literature. These antibiotics have become the most effective drugs for the treatment of Pseudomonas aeruginosa infections. Basically, good communication of respiratory care data is realized, thereby preventing respiratory care analysis of patients with heart failure.

Caring for Children With Medical Complexity in the Early COVID-19 Pandemic in an Ambulatory Primary Care Setting

BACKGROUND

Children with medical complexity (CMC) have multiple chronic conditions and require a high level of coordinated healthcare. The risk of COVID-19 among CMC is unclear.

OBJECTIVES

We aim to identify and describe the prevalence and experience of COVID-19 among CMC and their caregivers during the initial weeks of the COVID-19 pandemic in the NY metropolitan area.

METHODS

We performed a cross-sectional study of children enrolled in a structured clinical program for CMC at a large urban, academic general pediatrics practice in NY.

RESULTS

In our patient population (n = 132), 16 patients had a known exposure with parents being the most common exposure in 37.5% (n = 6). Two patients were hospitalized for COVID-19 while the remainder of the confirmed or suspected COVID-19 cases were managed as an outpatient.

CONCLUSIONS

Common sources of COVID-19 exposure were family members and home care providers. Almost all of our patients experienced interruption of medical care including missed therapies and visits.

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.

Respiratory concerns in children with medical complexity

Children with medical complexity (CMC) are a diverse group of children affected by a spectrum of chronic disorders and physiologic abnormalities. Due to their underlying disorders, they disproportionately experience respiratory comorbidities and complications. Respiratory-related complications that arise in this population often begin subtly and progress over time and can result in lung injury, respiratory insufficiency, and eventual chronic respiratory failure. CMC make up a substantial proportion of pediatric hospitalizations and healthcare expenditures, with respiratory-related illness being one of the leading causes of admission. It is, therefore, important for the practitioner caring for these children to have knowledge of the common respiratory concerns in this population as well as prevention and management strategies. This review will describe the most common respiratory concerns in CMC and will provide an overview of diagnosis and management.

Shared decision making for children with chronic respiratory failure-It takes a village and a process

BACKGROUND AND OBJECTIVES

Shared decision making (SDM) before nonurgent tracheostomy in a child with chronic respiratory failure (CRF) is often recommended, but has proven challenging to implement in practice. We hypothesize that utilization of the microsystem model for analysis of the complex ecosystem in which SDM occurs will yield insights that enable formation of a reproducible, measurable SDM process.

METHODS

Retrospective chart review of a case series of children with CRF in whom a SDM process was pursued. The process included a palliative care consult, a validated decision aid and 12 key questions designed to elucidate information integral to an informed decision. Investigators reviewed a single hospital admission for each child, focusing on the 3 core elements of a medical microsystem-the patient, the providers, and information.

RESULTS

Twenty-nine patients who met inclusion criteria ranged in age from 0 to 19.5 years (median 1.7) and remained in the hospital from 10 to 316 days (median 38). Patients were medically complex with multiple and varied respiratory diagnoses, multiple and varied comorbidities, and varying psychosocial environments. 14/29 children received tracheostomies. Each child encountered a mean of 6.2 medical specialties, 1.9 surgical specialties and 8.5 nonphysician led services. Answers to 12 key questions were not documented systematically and often not found in the electronic medical record.

CONCLUSION

A unique SDM microsystem is formed around each child but not optimally utilized. Explicit recognition of these microsystems would enable team formation and an SDM process comprised of measurable steps and communication patterns.

The utility of paired upper and lower respiratory tract sampling for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing in patients with artificial airways

Early in the coronavirus disease 2019 (COVID-19) pandemic, the CDC recommended collection of a lower respiratory tract (LRT) specimen for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) testing in addition to the routinely recommended upper respiratory tract (URT) testing in mechanically ventilated patients. Significant operational challenges were noted at our institution using this approach. In this report, we describe our experience with routine collection of paired URT and LRT sample testing. Our results revealed a high concordance between the 2 sources, and that all children tested for SARS-CoV-2 were appropriately diagnosed with URT testing alone. There was no added benefit to LRT testing. Based on these findings, our institutional approach was therefore adjusted to sample the URT alone for most patients, with LRT sampling reserved for patients with ongoing clinical suspicion for SARS-CoV-2 after a negative URT test.

Volume-assured pressure support mode for noninvasive ventilation: can it improve overnight adherence in children with neuromuscular disease?

Purpose

Volume-assured pressure support in noninvasive ventilation (VAPS-NIV) is a newer mode providing automatic pressure support adjustment to ensure a constant alveolar ventilation. Previous studies have shown that NIV effectiveness depends on patient adherence and tolerance. The aim of this study was to determine the adherence and efficacy of VAPS-NIV compared to spontaneous-time (S/T) mode in pediatric patients with neuromuscular disease (NMD).

Methods

This was a prospective observational study. Children with NMD who utilized NIV at home for ≥ 3 months were recruited from the Long-term ventilation clinic at The Hospital for Sick Children, Toronto, Canada, from July 1, 2015, to July 1, 2019. Baseline characteristics, date of initiation of NIV, and pulmonary function tests were recorded. Polysomnogram (PSG) data and adherence were recorded and analyzed comparing VAPS and S/T modes.

Results

Twenty children with NMD (17 male, 85%) were enrolled. The mean (SD) age at initiation of NIV was 11.6 ± 4.6 years. The median (IQR) duration of ventilation was 1.36 (0.80–2.98) years. The mean average daily usage and the median daily usage for VAPS mode and S/T mode were 8.4 ± 1.6 versus 7.2 ± 2.5 h (p = 0.012) and 8.6 ± 1.4 versus 7.8 ± 2.1 h (p = 0.022), respectively. There was no difference in sleep architecture, gas exchange, or parent proxy report of NIV tolerance between S/T and VAPS modes.

Conclusion

VAPS was associated with an improvement in adherence to therapy in children with NMD compared to S/T mode. Longitudinal studies are required to evaluate long-term clinical outcomes using VAPS mode in children with NMD.

Children dependent on respiratory support: A 10-year review from one pediatric postacute care hospital

OBJECTIVE

Pediatric postacute care hospitals (PACH) provide long-term care for children with medical complexity including children dependent on respiratory support. Descriptions of PACH respiratory care populations and outcomes, however, remain under-reported. Our aim was to describe demographics, respiratory outcome, and longitudinal trend of children with respiratory support admitted to a single PACH in the United States.

METHODS

Using electronic records from 2009 to 2018, data were examined for all children dependent on respiratory support. Children were identified for inclusion using respiratory level of care classifications (type of support) as outlined in hospital policy. Outcome was defined as change in level from first admission to final discharge. Number of admissions by level and year during the study timeframe were analyzed.

RESULTS

There were 1423 admissions for 767 children requiring respiratory support during the study timeframe. Children with higher respiratory classification level (eg, mechanical ventilation) at initial admission had more admissions to PACH (P < .001) and longer length of stays (P < .001). From first admission to final discharge, there was a significant change (reduction) in respiratory level (z = -4.588, P < .001). An increase in the overall number of admissions for children with respiratory support during the study timeframe was noted, with the largest increase for children requiring the highest level of support.

CONCLUSION

There has been a consistent increase in the number of children requiring respiratory support at admission to PACH. Reduction in respiratory support with postacute care occurs but children admitted with a higher level of support stay longer and experience multiple admissions.

Parental Conflict, Regret, and Short-term Impact on Quality of Life in Tracheostomy Decision-Making

OBJECTIVES

The prevalence of tracheostomy-dependence in critically ill children is increasing in the United States. We do not know the impact of this decision on parental outcomes. We aimed to determine the prevalence of decisional conflict and regret and explore the impact on quality of life among parents considering tracheostomy placement for their child.

SUBJECTS

Parents facing tracheostomy decision for their child.

DESIGN

Prospective, mixed-methods longitudinal study.

SETTING

PICU, cardiac ICU, and neonatal ICU of a single quaternary medical center.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Parents completed a decisional conflict survey at the time of tracheostomy decision and decisional regret and quality of life surveys at 2 weeks and 3 months after the decision regarding tracheostomy placement was made. We enrolled 39 parents, of which 25 completed surveys at all three time points. Thirty-five of 39 (89.7%) reported at least some decisional conflict, most commonly from feeling uninformed and pressured to make a decision. At 2 weeks, 13 of 25 parents (52%) reported regret, which increased to 18 of 25 participants (72%) at 3 months. Regret stemmed from feeling uninformed, ill-chosen timing of placement, and perceptions of inadequate medical care. At 2 weeks, the quality of life score was in the mid-range, 78.8 (SD 13.8) and decreased to 75.5 (SD 14.2) at 3 months. Quality of life was impacted by the overwhelming medical care and complexity of caring for a child with a tracheostomy, financial burden, and effect on parent's psychosocial health.

CONCLUSIONS

The decision to pursue tracheostomy among parents of critically ill children is fraught with conflict with worsening regret and quality of life over time. Strategies to reduce contributing factors may improve parental outcomes after this life-changing decision.

Respiratory Diagnostic Tools in Neuromuscular Disease

Children with neuromuscular disease (NMD) are at risk of acquiring respiratory complications. Both clinical assessments and respiratory diagnostic tests are important to optimize the respiratory health and care of such children. The following respiratory diagnostic tools and their utility for evaluating children with NMD are discussed in this article: lung function testing (spirometry and lung volumes), peak cough flow (PCF), respiratory muscle strength testing, oximetry, capnography, and polysomnography.
