Hospital admissions in children with cerebral palsy: a data linkage study

Respiratory admissions and impact of COVID-19 lockdowns for children with severe cerebral palsy

AIM

To explore factors contributing to the burden of respiratory admissions in children with severe cerebral palsy (CP) by comparing admissions to a single tertiary paediatric hospital before, during, and after the period of social restrictions implemented to reduce transmission of COVID-19 (lockdown period).

METHOD

For this observational study, three severe CP cohorts (pre-lockdown, lockdown, post-lockdown) were identified from a state-wide cerebral palsy register and linked to patient-level clinical and demographic data. Medical records were manually searched to identify respiratory hospitalizations. Frequency and details of admissions were compared across the three 2-year periods.

RESULTS

During the lockdown period, there were 24 hospitalizations for respiratory illness per 100 children compared to 37 and 47 in the pre-lockdown and post-lockdown periods (p < 0.001). Respiratory viruses (excluding picornaviruses) were detected in only 7% of lockdown admissions compared to 24% pre-lockdown and 30% post-lockdown. Sputum sampling was performed in 34% of admissions with gram-positive bacteria cultured in 6% admissions and gram-negative bacteria only in 18%.

INTERPRETATION

The study findings highlight an important dynamic contribution of viral infections to respiratory illnesses in children with severe CP and the potential to improve outcomes with personalized approaches based on defining individual factors predisposing to recurrent respiratory admissions.

Outpatient Management of Clinical Comorbidities in Children With Cerebral Palsy in Low- and Middle-Income Countries

BACKGROUND

Cerebral palsy (CP) is the most common physical disability of childhood. Its prevalence in low-and middle-income countries (LMICs) is over 3/1000 live births, about double the 1.6/1000 in high income countries (HICs). Multimorbidity is highly prevalent in CP. In LMICs, there are higher rates of prevalence, severity, comorbidities and mortality in children with CP. The evidence base for the recommendations in CP emanates overwhelmingly from studies conducted in HICs. Research conducted in LMICs settings, involving local clinicians, considering local context and investigating local solutions are urgently needed.

METHODS

This scoping review aimed to identify and synthesise current evidence on management of clinical comorbidities in children with CP in LMICs. The Joanna Briggs Institute guidelines were followed for the data extraction and analysis phases. The following questions guided the scoping review: What are the main clinical comorbidities in children with CP? What are the gold standards for diagnosis and treatment of these comorbidities? What options do we have to diagnose and treat these comorbidities in LMICs when gold standards are not available?

RESULTS

A total of 22 188 citations were identified by our search strategy, with 21 380 remaining after the removal of 808 duplicates. After screening titles and abstracts, 1918 citations progressed to full text review. A total of 194 articles met the eligibility criteria and were included in the review. The guiding questions of the review were answered for the following morbidities: respiratory impairments, dysphagia and aspiration, gastroesophageal reflux disease, drooling, obstructive sleep apnea syndrome, malnutrition, constipation, epilepsy, sleep disorders, spasticity, dystonia, pain, hip disorders, scoliosis and osteoporosis.

CONCLUSION

This article highlights the need for interventions adapted to the realities of LMICs. Empowering paediatricians and healthcare professionals in LMICs is crucial for early diagnosis and proactive interventions. Specific guidelines for LMICs can better guide professionals in managing these complex conditions.

The relationship between pneumonia and dental visits in patients with cerebral palsy: A nationwide registry-based cohort study in Taiwan

Background/purpose

In general, improving oral health can reduce the risk of pneumonia. The purpose of this retrospective cohort study was to investigate the risk of pneumonia between cerebral palsy (CP) cohort and non-CP cohort as well as the association of pneumonia with the number of dental visits in CP patients in Taiwan.

Materials and methods

We identified 10,544 patients who were diagnosed with CP between 2010 and 2019 from the Taiwan National Health Insurance Research Database. 63,264 individuals who had never been diagnosed with CP were captured and matched in a 6:1 ratio. Cox proportional hazard regression analysis was adopted to assess the hazard ratio (HR) of pneumonia between CP cohort and non-CP cohort.

Results

Our findings demonstrated that CP cohort had 2.619-fold risk for pneumonia as compared with non-CP cohort after adjustment (95 % CI = 2.574-2.813, P < 0.0001). Cox regression analysis indicated that the CP group had significantly higher incidence risk of pneumonia (log rank P < 0.0001). Higher risks of pneumonia in CP patients were associated with younger age, and lower urbanization level. Some comorbidities as well as history of pneumonia had the higher aHR for pneumonia within 180 days prior to index date. In addition, there was a positive association with the more than two dental visits for the decrease 0.887-fold incidence of pneumonia in CP-cohort as compared with no dental visit (95 % CI: 0.799-0.984).

Conclusion

Taken together, CP patients had a higher risk of pneumonia. Dental visits are beneficial for preventing the risk of pneumonia in CP patients. The patients with CP should receive regular dental checkup.

The management of Pseudomonas aeruginosa respiratory infection in children with cerebral palsy: A narrative review

Children with cerebral palsy have increased respiratory morbidity and mortality. Infection with Pseudomonas aeruginosa (PA) is associated with poorer outcomes, yet there are no formal guidelines to inform treatment of respiratory infection in children with cerebral palsy. This review explores the existing literature regarding management of PA-infection in children with cerebral palsy, with the aim of synthesising clinical recommendations and identifying gaps in current understanding. Medline (Ovid), PubMed and Embase were searched using keywords. Full-text articles involving the paediatric population and antimicrobial therapy were included. There was no limit on date of publication. Four retrospective case series were identified. Respiratory microbiology, in samples collected from a range of sites along the respiratory tract, was reported in three studies. Patients who received PA-specific antibiotics clinically improved. Two studies suggest that the use of suppressive inhaled anti-pseudomonal therapy may improve respiratory morbidity in the chronic setting. There is minimal evidence to guide management of PA respiratory infection in children with cerebral palsy. Children with cerebral palsy are at risk of developing bronchiectasis, so in the absence of high-quality evidence, management should be informed by extrapolating from the non-cystic fibrosis bronchiectasis guidelines. Further research examining surveillance and management of PA-infection in this population is required given that early intervention may prevent irreversible lung damage.

Outpatient encounters, continuity of care, and unplanned hospital care for children and young people with cerebral palsy

AIM

To describe the relationships between outpatient encounters, continuity of care, and unplanned hospital care in children/young people with cerebral palsy (CP).

METHOD

In this population-based data-linkage cohort study we included children/young people with CP identified in the New South Wales/Australian Capital Territory CP Register (birth years 1994-2018). We measured the frequency of outpatient encounters and unplanned hospital care, defined as presentations to emergency departments and/or urgent hospital admissions (2015-2020). Continuity of outpatient care was measured using the Usual Provider of Care Index (UPCI).

RESULTS

Of 3267 children/young people with CP, most (n = 2738, 83.8%, 57.6% male) had one or more outpatient encounters (123 463 total encounters, median six outpatient encounters per year during childhood). High UPCI was more common in children/young people with mild CP (Gross Motor Function Classification System levels I-III, with no epilepsy or no intellectual disability), residing in metropolitan and areas of least socioeconomic disadvantage. Low UPCI was associated with four or more emergency department presentations (adjusted odds ratio [aOR] 2.34; 95% confidence interval [CI] 1.71-3.19) and one or more urgent hospital admissions (aOR 2.02; 95% CI 1.57-2.61).

INTERPRETATION

Children/young people with CP require frequent outpatient services. Improving continuity of care, particularly for those residing in regional/remote areas, may decrease need for unplanned hospital care.

WHAT THIS PAPER ADDS

Many children with cerebral palsy use multiple and frequent outpatient services. Better continuity of care is associated with living in metropolitan and less socioeconomically disadvantaged areas. Outpatient service utilization reduces at the time of transition to adult services. High outpatient utilization is associated with unplanned hospital care. Decreased continuity of care is associated with unplanned hospital care.

Antibiotics for the treatment of lower respiratory tract infections in children with neurodisability: Systematic review

AIM

Determine the optimal antibiotic choice for lower respiratory tract infection (LRTI) in children with neurodisability.

METHODS

Embase, Ovid Emcare and MEDLINE were searched for studies from inception to January 2023. All studies, except case reports, focusing on the antibiotic treatment of LRTI in children, with neurodisabilities were included. Outcomes included length of stay, intensive care admission and mortality.

RESULTS

Nine studies met the inclusion criteria (5115 patients). All the studies were of low quality. The shortest length of stay was with anaerobic and gram-positive cover. Five studies used anaerobic, gram-positive and gram-negative cover (e.g., amoxicillin-clavulanic acid), which was frequently adequate. In one large study, it was better than gram-positive and gram-negative cover alone (e.g. ceftriaxone). Those unresponsive or more unwell at presentation improved faster on Pseudomonas aeruginosa cover (e.g., piperacillin-tazobactam).

CONCLUSION

In this context, anaerobic, gram-positive and gram-negative cover is just as effective as P. aeruginosa cover, supporting empiric treatment with amoxicillin-clavulanic acid. If there is a failure to improve, broadening to include P. aeruginosa could be considered. This is consistent with a consensus statement on the treatment of LRTI in children with neurodisability. An accepted definition for what constitutes LRTI in this cohort is required before designing prospective randomised trials.

Planned and unplanned hospital admissions and health-related school absence rates in children with neurodisability: Protocol for a population-based study using linked education and hospital data from England

Background

Neurodisability describes a broad set of conditions affecting the brain and nervous system which result in functional limitations. Children with neurodisability have more hospital admissions than their peers without neurodisability and higher rates of school absence. However, longitudinal evidence comparing rates of hospital admission and school absence in children with neurodisability to peers without neurodisability throughout school is limited, as is understanding about whether differences are greatest for planned care (e.g., scheduled appointments) or unplanned care. This study will describe rates of planned and unplanned hospital admissions and school absence due to illness and medical reasons throughout primary school (Reception to Year 6, ages 4 to 11 in England) for children with neurodisability and all other children, using linked individual-level health and education data.

Methods

We will use the ECHILD (Education and Child Insights from Linked Data) database, which links educational and health records across England. We will define a primary school cohort of children who were born in National Health Service-funded hospitals in England between 1 st September 2003 and 31 st August 2008, and who were enrolled in Reception (age 4/5) at state-funded schools. We will use hospital admissions records to identify children who have recorded indicators of neurodisability from birth up to the end of primary school (Year 6, age 10/11).

Results

We will describe rates of planned and unplanned hospital admissions and health-related school absence for three groups of children: those with a neurodisability indicator first recorded before beginning primary school, those with neurodisability first recorded during primary school, and those without a record of neurodisability before end of primary school.

Conclusions

We will further explore whether differences between these group vary across primary school years and by socioeconomic and demographic characteristics.

The cost of respiratory hospitalizations in children with cerebral palsy

AIM

To establish the burden of respiratory illness in cerebral palsy (CP) on the Western Australian health care system by quantifying the costs of respiratory hospitalizations in children with CP, compared with non-respiratory hospitalizations.

METHOD

A 2-year (2014-2015) retrospective study using linked hospital data (excluding emergency department visits), in a population of children with CP in Western Australia aged 18 years and under (median age at hospitalization 7 years; interquartile range 5-12 years).

RESULTS

In 671 individuals (57% male) there were 726 emergency hospitalizations, and 1631 elective hospitalizations. Although there were more elective hospitalizations, emergency hospitalizations were associated with longer stays in hospital, and more days in an intensive care unit, resulting in a higher total cost of emergency hospitalizations than elective hospitalizations (total costs: emergency AU$7 748 718 vs elective AU$6 738 187). 'Respiratory' was the leading cause of emergency hospitalizations, contributing to 36% of all emergency admission costs. For a group of high-cost inpatient users (top 5% of individuals with the highest total inpatient costs) the most common reason for hospitalization was 'respiratory'. Where non-respiratory admissions were complicated by an additional respiratory diagnosis, length of stay was greater.

INTERPRETATION

Respiratory hospitalizations in CP are a significant driver of health care costs. In the paediatric group, they are a burden for a subgroup of children with CP.

WHAT THIS PAPER ADDS

Respiratory illness is the most costly area for unplanned, emergency hospitalizations for children and young people with cerebral palsy. The top 5% of individuals with the highest total inpatient costs account for a disproportionate amount of health care costs.

Can RESPiratory hospital Admissions in children with cerebral palsy be reduced? A feasibility randomised Controlled Trial pilot study protocol (RESP-ACT)

INTRODUCTION

The most common cause of morbidity and mortality in children with severe cerebral palsy (CP) is respiratory disease. BREATHE-CP (Better REspiratory and Airway Treatment and HEalth in Cerebral Palsy) is a multidisciplinary research team who have conducted research on the risk factors associated with CP respiratory disease, a systematic review on management and a Delphi study on the development of a consensus for the prevention and management of respiratory disease in CP. These strategies have not been investigated; therefore, it is not known if implementation is feasible, if they improve patient outcomes or if they are acceptable for families.

METHODS AND ANALYSIS

Mixed-method feasibility pilot randomised controlled trial with economic analysis. Twenty children with CP aged 0-12 years who are at risk of respiratory disease will be followed up for 1 year. All children will receive baseline assessments for comparison. The control group will receive usual care from their treating teams. The intervention group will receive comprehensive assessments from physiotherapy, speech pathology and respiratory medicine. An individualised investigation and treatment plan will then be made. Participants in both groups will complete fortnightly patient-reported outcome surveys to assess symptoms and health service use. Analysis will include assessments of acceptability through qualitative interviews, implementation by ability to recruit, randomise and retain, practicality including costs of intervention and hospitalisation, and explore efficacy through quality-of-life surveys and decreased health service use for respiratory-related symptoms.

ETHICS AND DISSEMINATION

Ethics and governance approvals have been obtained through Child and Adolescent Health Service Human Research Ethics Committee. At completion, this study will lead to the design of the definitive protocol to test intervention efficacy that maximises recruitment, retention and adherence to interventions.

Supplementary Respiratory Therapy Improves Pulmonary Function in Pediatric Patients with Cerebral Palsy: A Systematic Review and Meta-Analysis

BACKGROUND

Despite medical advances, individuals with cerebral palsy (CP) face significant respiratory challenges, leading to heightened hospitalization rates and early mortality among this population. We hypothesize that integrating supplementary respiratory therapy into standard rehabilitation will result in significant improvements in pulmonary function, enhanced respiratory muscle strength, and an overall increase in the quality of life among pediatric patients with CP.

METHODS

A systematic search of literature across five databases was conducted, and random-effects meta-analyses were performed to assess the impact of supplementary respiratory therapy on (a) pulmonary function: forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FVC/FEV1 ratio, peak expiratory flow (PEF), and (b) respiratory muscle strength: maximal inspiratory and expiratory pressure (MIP, MEP), and (c) quality of life. Certainty of evidence was determined by the GRADE assessment.

RESULTS

Analysis of data from 11 eligible randomized controlled trials revealed clinically meaningful changes in pulmonary function. We found a relevant mean difference (MD) in absolute PEF of 0.50 L/s (95% confidence interval (CI): 0.19; 0.82 p = 0.0107). The certainty of the evidence ranged from moderate to high.

CONCLUSIONS

This study presents current evidence on the impact of various supplementary respiratory therapies for CP patients classified under gross motor function classification level I-IV, demonstrating clinically meaningful improvements in pulmonary function and respiratory muscle strength. These improvements suggest the potential for an enhanced quality of life. Our findings hold the promise of serving as a foundational reference for potential revisions to conventional rehabilitation care, incorporating supplementary respiratory therapy.

Adaptive Intervention to Prevent Respiratory Illness in Cerebral Palsy: Protocol for a Feasibility Pilot Randomized Controlled Trial

BACKGROUND

This study will pilot-test an innovative just-in-time adaptive intervention to reduce severe respiratory illness among children with severe cerebral palsy (CP). Our intervention program, Respiratory Exacerbation-Plans for Action and Care Transitions (RE-PACT), delivers timely customized action planning and rapid clinical response when hospitalization risk is elevated.

OBJECTIVE

This study aims to establish RE-PACT's feasibility, acceptability, and fidelity in up to 90 children with severe CP. An additional aim is to preliminarily estimate RE-PACT's effect size.

METHODS

The study will recruit up to 90 caregivers of children with severe CP aged 0 to 17 years who are cared for by a respiratory specialist or are receiving daily respiratory treatments. Participants will be recruited from pediatric complex care programs at the University of Wisconsin-Madison (UW) and the University of California, Los Angeles (UCLA). Study participants will be randomly assigned to receive usual care through the complex care clinical program at UW or UCLA or the study intervention, RE-PACT. The intervention involves action planning, rapid clinical response to prevent and manage respiratory illness, and weekly SMS text messaging surveillance of caregiver confidence for their child to avoid hospitalization. RE-PACT will be run through 3 successively larger 6-month trial waves, allowing ongoing protocol refinement according to prespecified definitions of success for measures of feasibility, acceptability, and fidelity. The feasibility measures include recruitment and intervention time. The acceptability measures include recruitment and completion rates as well as intervention satisfaction. The fidelity measures include observed versus expected rates of intervention and data collection activities. The primary clinical outcome is a severe respiratory illness, defined as a respiratory diagnosis requiring hospitalization. The secondary clinical outcomes include hospital days and emergency department visits, systemic steroid courses, systemic antibiotic courses, and death from severe respiratory illness.

RESULTS

The recruitment of the first wave began on April 27, 2022. To date, we have enrolled 30 (33%) out of 90 participants, as projected. The final wave of recruitment will end by October 31, 2023, and the final participant will complete the study by April 30, 2024. We will start analyzing the complete responses by April 30, 2024, and the publication of results is expected at the end of 2024.

CONCLUSIONS

This pilot intervention, using adaptive just-in-time strategies, represents a novel approach to reducing the incidence of significant respiratory illness for children with severe CP. This protocol may be helpful to other researchers and health care providers caring for patients at high risk for acute severe illness exacerbations.

Impact of COVID-19 on clinical practice of UK-based speech and language therapists working with school-aged children with neurodisability and oropharyngeal dysphagia: A survey

BACKGROUND

The COVID-19 pandemic and response changed clinical service delivery and practice for speech and language therapists (SLTs) in the United Kingdom. SLTs work with children with neurodisability regarding both difficulties with their communication and eating and drinking skills (oropharyngeal dysphagia). This survey aimed to specifically explore the impact of the COVID-19 pandemic on SLT practice for school-aged children with dysphagia.

METHODS

UK-based SLTs working with school-aged children with neurodisability and oropharyngeal dysphagia were recruited to share their perceptions on the impact of COVID-19 on practice. Four questions focusing on COVID-19 impact were part of a larger online survey exploring SLT clinical practice regarding mealtime management of children with neurodisability and oropharyngeal dysphagia, which included demographic information, service delivery, assessment and intervention practices. COVID-19 impact questions were a mixture of multiple choice and free text responses. The survey was disseminated using professional networks and social media, between 14 May and 30 July 2021. Data were analysed using descriptive statistics and qualitative content analysis.

RESULTS

One hundred and two participants answered at least one of the four COVID-19 questions. Eighty-two per cent of SLTs either agreed or strongly agreed that COVID-19 impacted on service delivery to children and families. Negative impacts on service delivery included school absences/closures, home visiting restrictions, families declining input and/or having barriers to telehealth use and the impact of mask wearing on interactions. Positive impacts included increased telehealth access and skills, increased contact with families and focus on children's eating and drinking function within the home environment. Participants aimed to maintain the increased contact with families alongside a hybrid service delivery approach of in-person and virtual appointments.

CONCLUSIONS

This survey provides novel information capturing SLT practice change across two waves of COVID-19 and return to in-person practice for UK children with neurodisability.

Barriers to and facilitators of a just-in-time adaptive intervention for respiratory illness in cerebral palsy: a qualitative study

OBJECTIVE

To understand caregiver, healthcare professional and national expert perspectives on implementation of a just-in-time adaptive intervention, RE-PACT (Respiratory Exacerbation-Plans for Action and Care Transitions) to prevent respiratory crises in severe cerebral palsy.

DESIGN

Qualitative research study.

SETTING

Paediatric complex care programmes at two academic medical institutions.

PARTICIPANTS

A total of n=4 focus groups were conducted with caregivers of children with severe cerebral palsy and chronic respiratory illness, n=4 with healthcare professionals, and n=1 with national experts.

METHODS

Participants viewed a video summarising RE-PACT, which includes action planning, mobile health surveillance of parent confidence to avoid hospitalisation and rapid clinical response at times of low confidence. Moderated discussion elicited challenges and benefits of RE-PACT's design, and inductive thematic analysis elicited implementation barriers and facilitators.

RESULTS

Of the 19 caregivers recruited, nearly half reported at least one hospitalisation for their child in the prior year. Healthcare professionals and national experts (n=26) included physicians, nurses, respiratory therapists, social workers and researchers. Four overarching themes and their barriers/facilitators emphasised the importance of design and interpersonal relationships balanced against health system infrastructure constraints. Intervention usefulness in crisis scenarios relies on designing action plans for intuitiveness and accuracy, and mobile health surveillance tools for integration into daily life. Trust, knowledge, empathy and adequate clinician capacity are essential components of clinical responder-caregiver relationships.

CONCLUSIONS

RE-PACT's identified barriers are addressable. Just-in-time adaptive interventions for cerebral palsy appear well-suited to address families' need to tailor intervention content to levels of experience, preference and competing demands.

Risk Factors for Mortality in Patients With Cerebral Palsy: A Systematic Review and Meta-Analysis

Cerebral palsy (CP) is a developmental and physical disorder with different degrees of severity. Since CP manifests itself in early childhood, numerous research studies have concentrated on children with CP. Patients with CP encounter different severity of motor impairments attributed to the damage or disturbance to the fetal or infant developing brain, which begins in early childhood and persists through adulthood. Patients with CP are more prone to mortality compared to the general population. This systematic review and meta-analysis aimed to assess the risk factors that predict and influence mortality in patients with CP. Systematic search for studies assessing the risk factors for mortality in CP patients that were conducted from 2000 to 2023 in Google Scholar, PubMed, and Cochrane Library was performed. R-One Group Proportion was used for statistical analysis and Newcastle-Ottawa Quality Assessment Scale (NOS) for quality appraisal. Of the 1791 total database searches, nine studies were included. Based on the NOS tool for quality appraisal, seven studies were of moderate quality, and two studies were rated as of high quality. The risk factors included pneumonia and other respiratory infections, neurological disorders, circulatory diseases, gastrointestinal infections, and accidents. Pneumonia (OR = 0.40, 95% CI = 0.31 - 0.51), neurological disorders (OR = 0.11, 95% CI = 0.08 - 0.16), respiratory infections (OR = 0.36, 95% CI = 0.31 - 0.51), cardiovascular and circulatory diseases (OR = 0.11, 95% CI = 0.04 - 0.27), gastrointestinal and metabolic causes (OR = 0.12, 95% CI = 0.06 - 0.22), and accidents (OR = 0.05, 95% CI = 0.04 - 0.07) were the risk factors assessed. It was concluded that multiple factors predict the risk of mortality in patients with CP. Pneumonia and other respiratory infections are associated with a high risk of mortality. Cardiovascular and circulatory diseases, gastrointestinal and metabolic disorders, and accidents are strongly linked to mortality in CP patients.

Understanding and managing respiratory infections in children and young adults with neurological impairment

INTRODUCTION

Patients with neurocognitive impairment (NI) have multiple medical needs, with respiratory problems leading to an important reduction in quality of life and life expectancy. We aimed to explain that the origin of chronic respiratory symptoms in patients with NI is multifactorial.

AREAS COVERED

In people with NI there is a high prevalence of swallowing dysfunction and hypersalivation inducing aspiration; cough efficacy is decreased resulting in chronic lung infection; sleep-disordered breathing is frequent and muscle mass is abnormal due to malnutrition. Technical investigations are not always specific and sensitive enough to better diagnose the causes of the respiratory symptoms; moreover, they can sometimes be difficult to perform in this vulnerable patient population. We provide a clinical pathway to adopt to identify, prevent, and treat respiratory complications in children and young adults with NI. A holistic approach in discussion with all care providers and the parents is highly recommended.

EXPERT OPINION

The care for people with NI and chronic respiratory problems is challenging. The interplay between several causative factors may be difficult to entangle. Well-performed clinical research in this field is largely missing and should be encouraged. Only then, evidence-based clinical care will become possible for this vulnerable patient group.

Epilepsy in children with cerebral palsy: a data linkage study

AIM

To compare the prevalence of epilepsy in children with cerebral palsy (CP) to peer controls and their differences in healthcare utilization.

METHOD

The Quebec CP registry was linked to the provincial administrative health database. Two CP cohorts were identified from the registry (n=302, 168 males, 1y 2mo-14y) and administrative data (n=370, 221 males, 2y 2mo-14y). A control cohort (n=6040, 3340 males, 10-14y) was matched by age, sex, and region to the CP registry cohort. Administrative data algorithms were used to define epilepsy cases. Data on hospitalizations and emergency department presentations were obtained.

RESULTS

Using the most sensitive epilepsy definition, prevalence was 42.05% in the CP registry, 43.24% in the CP administrative data, and 1.39% in controls. Prevalence rose with increasing Gross Motor Function Classification System level. Children with CP and epilepsy had increased number and length of hospitalizations and emergency department presentations compared to children with CP or epilepsy alone. Epilepsy accounted for approximately 5% of emergency department presentations and 10% of hospitalizations in children with epilepsy, with and without CP.

INTERPRETATION

Children with CP have an increased risk of epilepsy compared to their peers. Children with CP and coexisting epilepsy represent a unique subset with complex developmental disability and increased healthcare service utilization.

The Economic Burden and Determinant Factors of Parents/Caregivers of Children with Cerebral Palsy in Malaysia: A Mixed Methods Study

The economic burden is a major concern for parents/caregivers of children with cerebral palsy (CP). This study used the sequential explanatory mixed-method approach to explorethe economic burden on parents/caregivers with a CP child in Malaysia and the factors associated with the economic burden. The study period spanned April 2020 and December 2020. A total of 106 questionnaire respondents were selected for the quantitative part, and 15 were interviewed to obtain qualitative input. A retrospective costing analysis was conducted based on the cost data obtained from the questionnaire. The majority of the children were GrossMotor Function Classification System (GMFCS) Level 5 (71%), quadriplegic (63%), and aged >4 years (90%). The estimated annual median total economic burden on the parents/caregivers per child in 2020 was RM52,540.00 (~USD12,515.03), with indirect cost being the greatest cost (RM28,800.00, ~USD6860.16), followed by developmental cost (RM16,200.00, ~USD3858.84), direct healthcare cost (RM4540.00, ~USD1081.43) and direct non-healthcare cost (RM3000.00, ~USD714.60). The annual household income was identified as a significant determinant factor (p=0.019, 95% CI: 0.04, 0.40) of the economic burden. The participants’ responses during the in-depth interview in the qualitative part of the study supported the premise that socioeconomic factors play a substantial role in determining the total economic burden. Our findings may aid local policymakers when planning the greater provision of support to the affected families in the future, especially for the parents/caregivers of children with CP, who are facing socioeconomic challenges.

Determinants of hospital-based health service utilisation in cerebral palsy: a systematic review

OBJECTIVE

To systematically review and synthesize evidence of determinants associated with hospital-based health service utilisation among individuals with cerebral palsy (CP).

DATA SOURCES

Electronic databases MEDLINE, Embase, APA Psycinfo were searched from January 2000 to April 2020.

STUDY SELECTION

Observational studies were included that described people with CP, reported quantitative measures of hospital-based health service utilisation (inpatient, outpatient, emergency department), and based in high-income countries. We excluded studies that included only subsets of people with CP, or those that only reported therapy service utilisation.

DATA EXTRACTION

After initial screen, two reviewers reviewed full texts for inclusion and performed data extraction and risk of bias assessment using the Newcastle Ottawa scale. Determinants of health service utilisation were identified and categorised using the Andersen Behavioural Model.

DATA SYNTHESIS

Seventeen studies met inclusion criteria. Study quality was high. Twenty-six determinants were reported across eight Andersen Model characteristics. Individual predisposing factors such as sex showed no difference in health service utilisation; inpatient admissions decreased with increasing age during childhood and was lower in adults. Increased health service utilisation was associated with "individual need" including severe gross motor disability, epilepsy, developmental/ intellectual disability and gastrostomy-use across inpatient, outpatient and emergency department settings. There was little information reported on socio-demographic and health system contextual determinants.

CONCLUSIONS

CP health service utilisation was associated with age, severity and comorbidities. Improved understanding of determinants of health service utilisation can support health service access for people with CP.

Estimating the economic impacts of percutaneous coronary intervention in Australia: a registry-based cost burden study

OBJECTIVES

In this study, we sought to evaluate the costs of percutaneous coronary intervention (PCI) across a variety of indications in Victoria, Australia, using a direct per-person approach, as well as to identify key cost drivers.

DESIGN

A cost-burden study of PCI in Victoria was conducted from the Australian healthcare system perspective.

SETTING

A linked dataset of patients admitted to public hospitals for PCI in Victoria was drawn from the Victorian Cardiac Outcomes Registry (VCOR) and the Victorian Admitted Episodes Dataset. Generalised linear regression modelling was used to evaluate key cost drivers. From 2014 to 2017, 20 345 consecutive PCIs undertaken in Victorian public hospitals were captured in VCOR.

PRIMARY OUTCOME MEASURES

Direct healthcare costs attributed to PCI, estimated using a casemix funding method.

RESULTS

Key cost drivers identified in the cost model included procedural complexity, patient length of stay and vascular access site. Although the total procedural cost increased from $A55 569 740 in 2014 to $A72 179 656 in 2017, mean procedural costs remained stable over time ($A12 521 in 2014 to $A12 185 in 2017) after adjustment for confounding factors. Mean procedural costs were also stable across patient indications for PCI ($A9872 for unstable angina to $A15 930 for ST-elevation myocardial infarction) after adjustment for confounding factors.

CONCLUSIONS

The overall cost burden attributed to PCIs in Victoria is rising over time. However, despite increasing procedural complexity, mean procedural costs remained stable over time which may be, in part, attributed to changes in clinical practice.

Impact of Rehabilitation Intensity on 3-Year Mortality among Children with Moderate to Severe Cerebral Palsy: A Population-Based Cohort Study

Though numerous studies demonstrated the positive effect of rehabilitation on cerebral palsy (CP) children, there was no literature addressing the role of rehabilitation on mortality among children with CP. Therefore, we aimed to evaluate the impact of rehabilitation intensity on mortality among children with moderate to severe CP. This retrospective cohort study was conducted by National Health Insurance Research Database in Taiwan. Children (<12 years) with newly diagnosed moderate to severe CP between 1 January 2000 and 31 December 2013 were included. All patients were followed up for 3 years after CP diagnosis or death or until 31 December 2013. The intensity of rehabilitation therapy within 6 months after CP diagnosis was categorized into <6 times and ≥6 times. The Cox proportional hazard analysis was used to determine the association between rehabilitation intensity and all-cause mortality after adjusting age, sex, other demographic factors and comorbidities. Among 3936 severe CP children, 164 (4.2%) died during the 3-year follow-up period. The mortality rate was higher among patients receiving rehabilitation < 6 times within 6 months than those ≥6 times within 6 months after adjusting demographic profile and comorbidities (adjust HR (aHR): 1.96, 95% CI 1.33–2.89, p < 0.001). We found that patients who were younger (aHR: 0.84, 95% CI 0.76–0.92, p < 0.001), who were receiving inpatient care more than twice in 1 year before their CP diagnosis (aHR: 2.88; 95% CI: 1.96–4.23; p < 0.001), and who have pneumonia (aHR: 1.41, 95% CI 1.00–1.96, p = 0.047), epilepsy (aHR: 1.41, 95% CI: 1.02–1.95, p = 0.039) and dysphagia (aHR: 1.55, 95% CI: 1.06–2.26, p = 0.024) have higher risk of mortality. Rehabilitation ≥ 6 times within 6 months has a potentially positive impact on pediatric CP survival. Besides having a younger age, being hospitalized more than twice within a year before diagnosis and having pneumonia, epilepsy and dysphagia were modifiable risk factors in clinical practice for these children.

Effectiveness of the manual diaphragmatic stretching technique on respiratory function in cerebral palsy: A randomised controlled trial

BACKGROUND

Respiratory failure resulting from diaphragmatic muscle weakness is a major cause of long-term hospitalization in children with cerebral palsy (CP). Manual diaphragmatic stretching technique (MDST) can be directly applied to stretch diaphragmatic muscle and has been reported to improve respiratory function in patients with asthma and COPD. However, there have been no studies among CP. This study aimed to examine the effects of a six-week MDST course on respiratory function among CP.

METHODS

Fifty-three children with spastic CP were randomly assigned to experimental (n = 27) and control (n = 26) groups. The experimental group received MDST on non-consecutive days, three days per week for six weeks alongside standard physiotherapy (SDPT), while the control group received only SDPT. The outcome variables were diaphragmatic mobility, pulmonary function and chest wall expansion.

RESULTS

MDST significantly improved diaphragmatic mobility on both sides of the body, with a between-group difference of 0.97 cm (95% CI 0.55-1.39 cm, p < 0.001) for the right side and 0.82 cm (95% CI 0.35-1.29 cm, p = 0.001) for the left side. MDST significantly improved chest wall expansion at the xiphoid process and umbilical levels, with between-group differences of 0.57 cm (95% CI 0.12-1.20 cm, p = 0.013) and 0.87 cm (95% CI 0.31-1.43 cm, p = 0.003), respectively. There was no significant difference in pulmonary function testing between the groups.

CONCLUSION

MDST could significantly improve diaphragmatic mobility, and lower and abdominal chest wall expansion, among children with CP. Therefore, MDST could be considered as an additional technique for physiotherapy programmes, to improve diaphragmatic function in spastic CP.

Patterns of Health Service Use Among Young People With Cerebral Palsy in England

Background: Although the provision of healthcare for people with cerebral palsy (CP) is typically focussed on childhood, many people with CP require access to services periodically throughout their life. Few studies have examined patterns of health service use among young people with CP in England. Understanding patterns of use may inform future service development.

Objective: To describe patterns of visits to rehabilitation and medical professionals among ambulatory young people with CP living in England, and identify factors associated with service use.

Methods: Sixty-two young people with CP aged 10–19 years [mean (SD) age 13.7 (2.5) years] in Gross Motor Function Classification System (GMFCS) levels I-III reported visits to a range of health professionals, hospital admissions and visits to the emergency department over a median duration of 34 weeks (min–max: 12–34 weeks). Negative binomial models were used to examine factors associated with number of visits.

Results: Physiotherapists were the most commonly used professional, with 67.7% of participants visiting a physiotherapist at least once, followed by dentists (66.1%), general practitioners (48.4%), occupational therapists (40.3%) and orthopaedic surgeons (40.3%). Physiotherapists were also the most frequently visited professional with a total of 473 visits (13.3 visits per person-year). Speech and language therapists (5.0 visits per person-year), occupational therapists (4.5 visits per person-year) and nurses (4.3 per person-year) were the next most frequently visited professionals. Age, GMFCS level, and speech impairment were associated with rate of visits to a physiotherapist.

Conclusions: The proportion of young people who visited medical and rehabilitation professionals during the study period varied considerably depending on the profession. Generally, the proportion of young people using services was low. In the context of limited resources, data on service use in combination with data on unmet need, may support the reorganisation of services to maximise benefits to young people with CP.

Prevention and management of respiratory disease in young people with cerebral palsy: consensus statement

Respiratory illness is the leading cause of mortality in children with cerebral palsy (CP). Although risk factors for developing chronic respiratory illness have been identified, comprehensive clinical care recommendations for the prevention and management of respiratory illness do not currently exist. We invited over 200 clinicians and researchers from multiple disciplines with expertise in the management of respiratory illness in children with CP to develop care recommendations using a modified Delphi method on the basis of the RAND Corporation-University of California Los Angeles Appropriateness Method. These recommendations are intended for use by the wide range of practitioners who care for individuals living with CP. They provide a framework for recognizing multifactorial primary and secondary potentially modifiable risk factors and for providing coordinated multidisciplinary care. We describe the methods used to generate the consensus recommendations, and the overall perspective on assessment, prevention, and treatment of respiratory illness in children with CP. WHAT THIS PAPER ADDS: The first consensus statement for preventing and managing respiratory disease in cerebral palsy (CP). Risk factors for respiratory disease in CP should be identified early. Individuals with CP at risk of respiratory disease require regular assessment of risk factors. Effective partnerships between multidisciplinary teams, individuals with CP, and families are essential. Treatment of respiratory disease in individuals with CP must be proactive.

Healthcare use by children and young adults with cerebral palsy

AIM

To link routinely collected health data to a cerebral palsy (CP) register in order to enable analysis of healthcare use by severity of CP.

METHOD

The Northern Ireland Cerebral Palsy Register was linked to hospital data. Data for those on the CP register born between 1st January 1981 and 31st December 2009 and alive in 2004 were extracted, forming a CP cohort (n=1684; 57% males, 43% females; aged 0-24y). Frequencies of healthcare events, and the reasons for them, were reported according to CP severity and compared with those without CP who had had at least one hospital attendance in Northern Ireland within the study period.

RESULTS

Cases of CP represented 0.3% of the Northern Ireland population aged 0 to 24 years but accounted for 1.6% of hospital admissions and 1.6% of outpatient appointments. They had higher rates of elective admissions and multi-day hospital stays than the general population. Respiratory conditions were the most common reason for emergency admissions. Those with most severe CP were 10 times more likely to be admitted, and four times more likely to attend outpatients, than those with mild CP.

INTERPRETATION

Linkage between a register and routinely collected healthcare data provided a confirmed cohort of cases of CP that was sufficiently detailed to analyse healthcare use by disease severity.

Experiences and Needs of Parents Caring for Children with Cerebral Palsy: A Systematic Review

OBJECTIVE

Caregiver burden of parents of children with disabilities is negatively associated with parental quality of life and psychosocial well-being and has been identified as a public health concern. Reviews have consolidated the experiences of these parents, but little is understood about the unique challenges faced by parents of children with cerebral palsy (CP). We aim to conduct an in-depth synthesis of the experiences and needs of parents of children with CP to better support them.

METHODS

Six electronic databases were searched systematically for qualitative research, and a thematic synthesis was performed.

RESULTS

Seventeen studies from 1988 to 2019 encapsulating the experiences of 226 parents were included in this review. Four themes and 11 subthemes were identified: (1) self: the caregiver-parent trajectory (coming to terms with the fact, physical and emotional demands, and a nice outlet), (2) family: maintaining the family unit (juggling multiple children and parenting as a co-occupation), (3) society: social repercussions (facing public discrimination, rejection by extended family, and loss of freedom), and (4) parents' wish list (open communication and caring attitudes, funding and health care accessibility, social integration, and inclusivity). Apart from emotional adaptation and physical childcare difficulty, parents indicated a need for more information on health care services, funding, better attitudes and empathy from health care providers, properly trained educators, disability-friendly fixtures, and more public awareness.

CONCLUSION

The findings in this review provide insight into the true experiences and needs of parents caring for children with CP and will aid clinicians in the development of family-centered care pathways for these patients.

Hospitalizations in School-Aged Children with Cerebral Palsy and Population-Based Controls

OBJECTIVE

To compare hospitalizations among children with cerebral palsy (CP) and healthy controls and to identify factors associated with hospitalizations in children with CP.

METHODS

This retrospective cohort study linked data from a provincial CP Registry and administrative health databases. The CP cohort was comprised of children born from 1999 to 2002. Age, sex, and region-matched controls were identified from administrative health databases. Mean differences, relative risk (RR), and 95% confidence intervals (CIs) were calculated.

RESULTS

A total of 301 children with CP were linked to administrative health data and matched to 6040 controls. Mean hospitalizations per child during the study period were higher in children with CP compared to controls (raw mean difference (RMD) 5.0 95% CI 4.7 to 5.2) with longer length of stay (RMD 2.8 95% CI 1.8 to 3.8) and number of diagnoses per hospitalization (RMD 1.6 95% CI 1.4 to 1.8). Increased risk of hospitalization was observed in non-ambulant children with CP (RR 1.12 95% CI 1.01 to 1.22) compared to ambulant children and among those with spastic tri/quadriplegic CP compared to other CP subtypes (RR 1.15, 95% CI 1.05 to 1.27). Feeding difficulties (RR 1.20 95% CI 1.13 to 1.27), cortical visual (RR 1.22 95% CI 1.13 to 1.32), cognitive (RR 1.16 95% CI 1.04 to 1.30), and communication impairment (RR 1.26 95% CI 1.10 to 1.44) were associated with increased hospitalizations.

CONCLUSIONS

Children with CP face more frequent, longer hospital stays than peers, especially those with a more severe CP profile. Coordinated interdisciplinary care is needed in school-aged children with CP and medical complexity.

Profile of hospital admissions for adults with cerebral palsy: a retrospective cohort study

AIM

To retrospectively profile acute hospital admissions for a defined cohort of adults with cerebral palsy (CP).

METHOD

Five years of health service data were interrogated to identify acute health service use by adults with CP. Admission types were described, admission reasons categorized using International Classification of Diseases, 10th Revision codes, and length of stay (LOS) calculated. Any differences between paediatric and adult subsets were explored.

RESULTS

Individuals with CP constituted 2922 admissions. Of these, 850 (29%) were adult admissions. There were significant differences between admission reasons for paediatric and adult cohorts, with adults predominantly seeking hospital admission for emergency rather than planned care (emergency reason: adults 62.1%, paediatrics 25.2%; p<0.001). The median adult admission LOS was longer than that of children (p<0.001). The primary diagnosis admission reason in the adult data set was respiratory illness (20%) followed closely by gastrostomy dysfunction (19%).

INTERPRETATION

Adults with CP predominantly access acute hospital services for emergency health care. A high frequency of admissions is associated with respiratory illness and gastrostomy dysfunction in adults with CP. What this paper adds Adults with cerebral palsy (CP) access acute inpatient services for emergency health care. Hospital admissions are predominantly because of respiratory illness and gastrostomy dysfunction. Admission length of stay is longer for adults than children. Many adults with CP require hospitalization more than once a year.

Evaluation and Management of Respiratory Illness in Children With Cerebral Palsy

Cerebral palsy (CP) is the most common cause of disability in childhood. Respiratory illness is the most common cause of mortality, morbidity, and poor quality of life in the most severely affected children. Respiratory illness is caused by multiple and combined factors. This review describes these factors and discusses assessments and treatments. Oropharyngeal dysphagia causes pulmonary aspiration of food, drink, and saliva. Speech pathology assessments evaluate safety and adequacy of nutritional intake. Management is holistic and may include dental care, and interventions to improve nutritional intake, and ease, and efficiency of feeding. Behavioral, medical, and surgical approaches to drooling aim to reduce salivary aspiration. Gastrointestinal dysfunction, leading to aspiration from reflux, should be assessed objectively, and may be managed by lifestyle changes, medications, or surgical interventions. The motor disorder that defines cerebral palsy may impair fitness, breathing mechanics, effective coughing, and cause scoliosis in individuals with severe impairments; therefore, interventions should maximize physical, musculoskeletal functions. Airway clearance techniques help to clear secretions. Upper airway obstruction may be treated with medications and/or surgery. Malnutrition leads to poor general health and susceptibility to infection, and improved nutritional intake may improve not only respiratory health but also constipation, gastroesophageal reflux, and participation in activities. There is some evidence that children with CP carry pathogenic bacteria. Prophylactic antibiotics may be considered for children with recurrent exacerbations. Uncontrolled seizures place children with CP at risk of respiratory illness by increasing their risk of salivary aspiration; therefore optimal control of epilepsy may reduce respiratory illness. Respiratory illnesses in children with CP are sometimes diagnosed as asthma; a short trial of asthma medications may be considered, but should be discontinued if ineffective. Overall, management of respiratory illness in children with CP is complex and needs well-coordinated multidisciplinary teams who communicate clearly with families. Regular immunizations, including annual influenza vaccination, should be encouraged, as well as good oral hygiene. Treatments should aim to improve quality of life for children and families and reduce burden of care for carers.

Hospital admissions in children with developmental disabilities from ethnic minority backgrounds

AIM

To compare hospital admission patterns after the first year of life in Australian children with developmental disabilities and children with no known disability, according to maternal country of birth and Indigenous status.

METHOD

This was a retrospective cohort study using linked data across health, disability, and hospital admission databases. The study investigated 656 174 children born in Western Australia between 1983 and 2008 with a total of 1 091 834 records of hospital admissions.

RESULTS

Children with no known disability born to Indigenous mothers had the highest rate of hospital admissions compared to children of non-Indigenous mothers. Children of foreign-born mothers from low-income countries had the highest rate of hospital admissions if disability was present. Children with cerebral palsy (CP) with or without associated intellectual disability had the highest rate of hospital admissions among children with developmental disability, especially if mothers were foreign-born.

INTERPRETATION

Children with CP and intellectual disability, particularly from minority backgrounds (Indigenous Australian and foreign-born mothers), were at higher risk of being admitted to hospital after the first year of life.

WHAT THIS PAPER ADDS

Hospital admissions in Australian children with and without disabilities differ according to maternal country of birth. Hospital admission rates in children without a developmental disability were greatest for Australian-born Indigenous children. Disabled Australian-born children of foreign-born mothers from low-income countries had the highest hospital admission rates. Hospital admission risk was greatest for Australian-born children with cerebral palsy, especially if mothers were foreign-born.

Prevalence, trends, and correlates of malnutrition among hospitalized children with cerebral palsy

AIM

This cross-sectional study characterized the prevalence, trends, sociodemographic factors, and clinical factors that are associated with a coded diagnosis of malnutrition (CDM) among hospitalized children with cerebral palsy (CP) in the USA.

METHOD

We used data from the 2002 to 2015 National Inpatient Sample database and restricted the analysis to hospitalized children with CP between 2 and 17 years of age. International Classification of Diseases, Ninth Edition, Clinical Modification diagnosis codes for CP, malnutrition, and comorbidities associated with CP were used to characterize hospitalizations for this population. Logistic regression models were conducted to identify the sociodemographic factors and comorbidities associated with a diagnosis of malnutrition.

RESULTS

The average documented rate of CDM among hospitalized children with CP was 7.9% and nearly doubled during the study period. The model suggests that younger age, non-white ethnicity, lower income, and non-private insurance/payer status were associated with increased odds of documented malnutrition. Concomitant inpatient diagnoses of epilepsy, dysphagia, scoliosis, reflux, and constipation were associated with higher rates of CDM.

INTERPRETATION

The rate of CDM in hospitalized patients with CP is well under the estimated clinical prevalence of 30% to 40%. Multiple sociodemographic, hospital, and clinical factors are associated with higher rates of CDM.

WHAT THIS PAPER ADDS

The documented rate of malnutrition in hospitalized children with cerebral palsy (CP) averaged 7.9% yearly. For hospitalized children with CP, documentation of malnutrition nearly doubled between 2002 and 2015. Economically disadvantaged and minority ethnic groups had a greater likelihood of malnutrition documentation. Inpatient malnutrition documentation was more likely with some comorbidities indicative of greater impairments. Gastrointestinal disorders increased the likelihood of an inpatient-documented diagnosis of malnutrition.

Effects of salivary gland botulinum Toxin-A on drooling and respiratory morbidity in children with neurological dysfunction

OBJECTIVE

To describe the effects of salivary gland Botulinum Toxin-A (SG BoNT-A) on children with drooling due to neurological dysfunction.

METHODS

This was a 3½-year prospective observational case series design of children referred for SG BoNT-A injections at a pediatric hospital (2010-2014). Outcomes were parent-reported severity, frequency, impact of drooling, and respiratory morbidity; and, from hospital records, number of respiratory hospital admissions.

RESULTS

Out of 17 children treated, complete data were available for 15 (including 8 boys) aged 3-14 years (Mean = 9.9 years; SD = 3.4), with a combined total of 71 injections. Most had cerebral palsy (n = 11), classified as Level V (n = 10) or IV (n = 1) on the Gross Motor Function Classification Scale (GMFCS). In almost all instances, parents reported reductions in severity, frequency, and impact of drooling, and parent-reported respiratory morbidity. Among those with posterior drooling (n = 12), most children (n = 10) did not have advanced respiratory disease. A trend towards reduced respiratory-related hospital admissions was observed during SG BoNT-A treatment periods.

CONCLUSION

SG BoNT-A can improve severity, frequency, and impact of drooling. It can also reduce respiratory-related hospital admissions in children with posterior drooling without advanced respiratory disease. For children with advanced respiratory disease, it may reduce severity and impact of drooling.

Interventions for management of respiratory disease in young people with cerebral palsy: A systematic review

BACKGROUND

Respiratory disease is a leading cause of hospitalizations and deaths in young people with cerebral palsy (CP). It is insidious and multifactorial. Clinical management can be complex. This systematic review describes effects of interventions for the prevention and management of respiratory disease in young people with CP.

METHODS

Nine databases (Cochrane, CINAHL, Embase, EMCare, MEDLINE, PEDro, OpenGrey, ScienceDirect, and SpeechBITE) were searched. Eligibility criteria were as follows: the population included at least 50% individuals with CP aged under 26 years, the intervention was for chronic respiratory illness, the outcomes were any measurable indicators of respiratory health or morbidity; the study design could be any original study reporting effects of an intervention on measurable outcomes, and the study was published January 1998 or later. The American Academy for Cerebral Palsy and Developmental Medicine methodology guided study appraisal and synthesis. The review was registered with PROSPERO (reference number CRD42018086314).

RESULTS

The search yielded 3,347 papers; 37 papers (reporting 34 studies) of these met the eligibility criteria. They included 582 participants with CP (ranging from 1 to 77 across studies) with ages from 5 months to 25 years. Interventions were diverse and included: airway clearance techniques, exercise, positioning, mealtime management, salivary management, upper airway interventions, antibiotics, gastro-intestinal interventions, and spinal surgery. There were no interventions aimed at prevention of respiratory disease in this population. Research designs were classified as Levels 2 (n = 3), 3 (n = 2), 4 (n = 25), and 5 (n = 4).

CONCLUSIONS

Evidence for most respiratory interventions for young people with CP is absent or weak. No controlled trials demonstrated significant effects on respiratory morbidity, owing to their scarcity, weak designs, and inadequate power. There is an urgent need for well-designed prospective controlled studies investigating prevention and management of respiratory disease in young people with CP.

Identifying cerebral palsy from routinely-collected data in England and Wales

Purpose: An observational study using routinely-collected health care data to describe the extent to which children and young people (CYP) with cerebral palsy (CP) can be identified and the prevalence of CP can be estimated.

Patients and methods: Routinely-collected anonymized data, for CYP (aged 0–25 years old between 1 January 2004 and 31 December 2014) were analyzed in two linked datasets, from England and Wales respectively. Datasets included National Health Service; General Practitioner (GP), inpatients, outpatients, and national mortality records. CP was identified using ICD-10 codes G80.0–G83.3 and equivalent Read v2 codes. Ascertainment rates of CP were identified for each data source and compared between countries. Frequency and consistency of coding were investigated, and prevalence of CP estimated.

Results: A total of 7,113 and 5,218 CYP with CP were identified in the English and Welsh datasets respectively. Whilst the majority of CYP with CP would be expected to attend their GP, 65.3% (4,646/7,113) of English and 65.1% (3,396/5,218) of Welsh cases were ascertained from GP datasets. Further cases were identified solely in inpatient datasets (2,410 in England, 1,813 in Wales). Few cases were coded for CP within outpatient datasets. Four character codes that specified CP type were rarely used; one in five health care records were coded both with G80 codes (explicitly CP) and with G81–83 codes (other paralytic syndromes) or equivalent Read codes. Estimated period prevalence of CYP with CP was 2.5–3.4 per 1,000 in England and 2.4–3.2 per 1,000 in Wales.

Conclusion: In England and Wales, coding of CP in routine data is infrequent, inconsistent, non-specific, and difficult to isolate from conditions with similar physical signs. Yet the prevalence estimates of CP were similar to those reported elsewhere. To optimize case recognition we recommend improved coding quality and the use of both primary and secondary care datasets as a minimum.

Survival and mortality in cerebral palsy: observations to the sixth decade from a data linkage study of a total population register and National Death Index

Background

Likely duration of survival of children described as having cerebral palsy is of considerable interest to individuals with cerebral palsy, their families, carers, health professionals, health economists and insurers. The aim of this paper is to describe patterns of survival and mortality to the sixth decade in a geographically defined population of people with cerebral palsy stratified according to the clinical description of their impairments in early childhood.

Methods

Identifiers of persons born in Western Australia 1956–2011, registered with cerebral palsy on the Western Australian Register of Developmental Anomalies and surviving at least 12 months, were linked to the Australian National Death Index in December 2014. Patterns of mortality were investigated using survival analysis methods.

Results

Of 3185 eligible persons, 436 (13.7%) had died. Of that sample the 22% with the mildest impairment had survival patterns similar to the general population. Mortality increased with increasing severity of impairment. Of 349 (75%) with available cause of death data, 58.6% were attributed to respiratory causes, including 171 (49%) to pneumonia at a mean age of 14.6 (sd 13.4) years of which 77 (45%) were attributed to aspiration.

For the most severely impaired, early childhood mortality increased in succeeding decades of birth cohorts from 1950s to 1990 with 20% dying by 4 years of age in the 1981–1990 birth cohort; it then decreased for subsequent birth cohorts, 20% mortality not being attained until 15 years of age. However by 20 years of age mortality of the most severely impaired born in the 1991–2000 birth cohort exceeded that of all other birth cohorts.

Remaining life expectancies by age to 50 years have been estimated for two strata with more severe impairments.

Conclusion

For 22% of individuals with cerebral palsy with mild impairment survival to 58 years is similar to that of the general population. Since 1990 mortality for those with severe cerebral palsy in Western Australia has tended to shift from childhood to early adulthood.

Longitudinal trajectories and reference centiles for the impact of health conditions on daily activities of children with cerebral palsy

AIM

First, to describe the impact of health conditions on daily activities over time in children with cerebral palsy (CP) and to create age-specific reference centiles. Second, to determine the amount of change typical over a 1-year period, across Gross Motor Function Classification System (GMFCS) levels.

METHOD

A prospective, cohort design, with five assessments over 2 years, involved 708 children with a confirmed diagnosis of CP participating in the On Track Study (396 males, 312 females; mean age 6y [SD 2y 7mo]; range 18mo-12y at first assessment; 32.1% in GMFCS level I, 22.7% in GMFCS level II, 11.2% in GMFCS level III, 18.2% in GMFCS level IV, 15.7% in GMFCS level V). The impact of health conditions on daily activities was assessed using the Child Health Conditions Questionnaire. Data were analyzed using mixed-effects models and quantile regression.

RESULTS

Linear longitudinal trajectories describe the relatively stable impact of health conditions over time for each functional level for children aged 2 years to 12 years, with the lowest scores (least impact) in GMFCS level I and the highest scores (highest impact) in GMFCS level V. Centiles were created for children in each GMFCS level. A system to interpret the magnitude of change over time in centiles was developed.

INTERPRETATION

Longitudinal trajectories of co-occurring health conditions assist with understanding children's prognoses. Centiles assist in understanding a child's experience relative to children in similar GMFCS levels. Guidelines are provided to determine if children are progressing 'as expected', 'better than expected' or 'more poorly than expected' in regard to the impact of health conditions on daily activities.

WHAT THIS PAPER ADDS

For children with cerebral palsy, the mean impact of health conditions on daily activities is relatively stable. Significant intraindividual and interindividual variability for the impact of health conditions exists, which complicates prognosis. Centiles enable interpretation of the impact of health conditions relative to Gross Motor Function Classification System level.

Predicting respiratory hospital admissions in young people with cerebral palsy

OBJECTIVE

To determine the early predictors of respiratory hospital admissions in young people with cerebral palsy (CP).

DESIGN

A 3-year prospective cohort study using linked data.

PATIENTS

Children and young people with CP, aged 1 to 26 years.

MAIN OUTCOME MEASURES

Self-reported and carer-reported respiratory symptoms were linked to respiratory hospital admissions (as defined by the International Statistical Classification of Diseases and Related Health Problems 10th Revision codes) during the following 3 years.

RESULTS

482 participants (including 289 males) were recruited. They were aged 1 to 26 years (mean 10 years, 10 months; SD 5 years, 11 months) at the commencement of the study, and represented all Gross Motor Function Classification Scale (GMFCS) levels. During the 3-year period, 55 (11.4%) participants had a total of 186 respiratory hospital admissions, and spent a total of 1475 days in hospital. Statistically significant risk factors for subsequent respiratory hospital admissions over 3 years in univariate analyses were GMFCS level V, at least one respiratory hospital admission in the year preceding the survey, oropharyngeal dysphagia, seizures, frequent respiratory symptoms, gastro-oesophageal reflux disease, at least two courses of antibiotics in the year preceding the survey, mealtime respiratory symptoms and nightly snoring.

CONCLUSIONS

Most risk factors for respiratory hospital admissions are potentially modifiable. Early identification of oropharyngeal dysphagia and the management of seizures may help prevent serious respiratory illness. One respiratory hospital admission should trigger further evaluation and management to prevent subsequent respiratory illness.

Systematic review of the economic impact of cerebral palsy

BACKGROUND

Cerebral palsy (CP) and its associated conditions can pose a significant economic burden on families, the health care system and the general economy. The boundary for inclusion of costs in research can vary substantially across studies.

AIMS

To summarize the evidence for burden of disease for CP including the impacts on the health system, the community and carers.

METHODS

Literature was identified from Ovid Medline, Embase, CINHAL, PsyInfo, Econlit, Health Economic Evaluation Database (HEED) and NHS Economic Evaluation Database (NHS EED) in the Cochrane Library. The search was restricted to articles published in English between 1970 and April 2016. All costs were converted to $USD 2016 price.

RESULTS

Twenty-two articles were included. Studies varied from snapshot cost descriptions to more complex lifetime estimates, from prevalence-based to incidence-based studies, and from inclusion to exclusion of non-medical costs. There was a strong positive relationship between CP severity and expenditure. Significant costs were incurred by families and the welfare system to facilitate school and community engagement.

CONCLUSION

Facilitating participation for people with CP involves substantial expense. The size, nature and distribution of the economic burden emphasises the importance of finding effective strategies to reduce the risk and severity of CP, together with how it is financed.

Educational outcomes for children with cerebral palsy: a linked data cohort study

AIM

To identify a cohort of children with cerebral palsy (CP) from hospital data; determine the proportion that participated in standardized educational testing and attained a score within the normal range; and describe the relationship between test results and motor symptoms.

METHOD

This population-based retrospective cohort study used data from New South Wales, Australia. We linked hospital data for children younger than 16 years of age admitted between 1st July 2000 and 31st March 2014 to education data from 2009 to 2014. Hospital diagnosis codes were used to identify a cohort of children with CP (n=3944) and describe their motor symptoms. Educational outcomes in the CP cohort were compared with those among children without CP.

RESULTS

Of those with educational data (n=1770), 46% were exempt from reading assessment because of intellectual or functional disability, 7% were absent or withdrawn from testing and 47% participated in testing. About 30% of all children with educational data had test scores in the normal range. The proportion was greatest among those with hemiplegia (>40%) and lowest among those with tetraplegia (<10%).

INTERPRETATION

One-third of children with CP participated in standardized testing and achieved a result in the normal range. The proportions were lower in children with more severe motor symptoms.

WHAT THIS PAPER ADDS

From 2009 to 2014, most Australian children with cerebral palsy (CP) attended a mainstream school. The rate of disability-related exemption from standardized educational testing was almost 50%. Thirty per cent of children with CP achieved educational scores in the normal range.

Exploring quality of life of children with cerebral palsy and intellectual disability: What are the important domains of life?

BACKGROUND

Although it is estimated that half of all children with cerebral palsy also have comorbid intellectual disability, the domains of quality of life (QOL) important for these children are not well understood. The aim of this study was to identify important domains of QOL for these children and adolescents.

METHODS

Due to the children's communication impairments, qualitative semi-structured interviews were conducted with 18 parents. The children (9 males) had a median age of 12 (range 7 to 17) years at interview and nearly two thirds were classified as Gross Motor Function Classification System IV or V. A grounded theory approach was used to identify domains of QOL.

RESULTS

The 11 domains identified as important to QOL were physical health, body comfort, behaviour and emotion, communication, predictability and routine, movement and physical activity, nature and outdoors, variety of activity, independence and autonomy, social connectedness, and access to services.

CONCLUSIONS

The domains of QOL that emerged from this study will be useful for professionals who support children with cerebral palsy and their families. They will also be important for developing a QOL instrument essential for informing the development of interventions and their monitoring and evaluation.

Do children with neurological disabilities use more inpatient resources: an observational study

Background

Advances in healthcare have improved the survival of children with neurological disabilities (ND). Studies in the US have shown that children with ND use a substantial proportion of resources in children’s hospitals, however, little research has been conducted in the UK. We aimed to test the hypothesis that children with neurological disabilities use more inpatient resources than children without neurological disabilities, and to quantify any significant differences in resource use.

Methods

A retrospective observational study was conducted, looking at the number of hospital admissions, total inpatient days and the reason for admissions for paediatric inpatients from January 1st to March 31st 2015. Inpatients were assigned into one of three groups: children without ND, children with one ND, and children with more than one ND.

Results

The sample population included 942 inpatients (mean age 6y 6mo). Children with at least one ND accounted for 15.3% of the inpatients, 17.7% of total hospital inpatient admission episodes, and 27.8% of the total inpatients days. Neurological disability had a statistically significant effect on total hospital admissions (p < 0.001). Neurological disability also had a statistically significant effect on total inpatient days (p < 0.001). Neurological disability increased the length of inpatient stay across medicine, specialties, and surgery.

Conclusions

Children with ND had more frequent hospital admission episode and longer inpatient stays. We identified a smaller group within this population, with arguably more complex neurological disabilities, children with more than one ND. This group had the highest number of admissions and longest inpatient stays. More frequent hospital admissions and longer inpatient stays may place children with ND at greater risk of the adverse effects of hospitalisations. We recommend further investigations looking at each the effects of the different categories of ND on inpatient resource use, and repeat of this study at a national level and over a longer period of time.
