Epidemiology of gastrostomy insertion for children and adolescents with intellectual disability

Growth patterns in individuals with CDKL5 deficiency disorder

AIM

To compare growth in individuals with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder with population norms and to investigate the effect of gastrostomy on growth.

METHOD

The longitudinal study included 353 individuals from the International CDKL5 Disorder Database with any anthropometric measurement in baseline and/or follow-up questionnaires. The British 1990 growth reference was used to determine the age- and sex-standardized z-score. Repeated cross-sectional data were fitted using a Gaussian linear regression model with generalized estimating equations.

RESULTS

All growth parameters were below the general population norm (mean z-scores: weight -0.97, height -0.65, body mass index [BMI] -0.81, head circumference -2.12). The disparity was particularly pronounced for all anthropometric measurements after 4 years of age except for BMI. Moreover, individuals with gastrostomy placement were shown to have a larger decrease than those without.

INTERPRETATION

In addition to weight, height, and BMI, head circumference was also compromised in this disorder. Microcephaly could be considered a helpful diagnostic feature, especially in adults. Any benefit of gastrostomy on weight and BMI was mainly seen in the early years.

Recurrent Intensive Care Episodes and Mortality Among Children With Severe Neurologic Impairment

Importance

Children requiring care in a pediatric intensive care unit (PICU) are known to have increased risk of subsequent mortality. Children with severe neurologic impairment (SNI)-who carry neurologic or genetic diagnoses with functional impairments and medical complexity-are frequently admitted to PICUs. Although recurrent PICU critical illness episodes (PICU-CIEs) are assumed to indicate a poor prognosis, the association between recurrent PICU-CIEs and mortality in this patient population is poorly understood.

Objective

To assess the association between number of recent PICU-CIEs and survival among children with severe neurologic impairment.

Design, Setting, and Participants

This population-based retrospective cohort study used health administrative data from April 1, 2002, to March 31, 2020, on 4774 children born between 2002 and 2019 with an SNI diagnosis code in an Ontario, Canada, hospital record before 16 years of age and a first PICU-CIE from 2002 to 2019. Data were analyzed from November 2021 to June 2023.

Exposure

Pediatric intensive care unit critical illness episodes (excluding brief postoperative PICU admissions).

Main Outcome and Measures

One-year survival conditioned on the number and severity (length of stay >15 days or use of invasive mechanical ventilation) of PICU-CIEs in the preceding year.

Results

In Ontario, 4774 children with SNI (mean [SD] age, 2.1 [3.6] months; 2636 [55.2%] <1 year of age; 2613 boys [54.7%]) were discharged alive between 2002 and 2019 after their first PICU-CIE. Ten-year survival after the initial episode was 81% (95% CI, 79%-82%) for children younger than 1 year of age and 84% (95% CI, 82%-86%) for children 1 year of age or older; the age-stratified curves converged by 15 years after the initial episode at 79% survival (95% CI, 78%-81% for children <1 year and 95% CI, 75%-84% for children ≥1 year). Adjusted for age category and demographic factors, the presence of nonneurologic complex chronic conditions (adjusted hazard ratio [AHR], 1.70 [95% CI, 1.43-2.02]) and medical technology assistance (AHR, 2.32 [95% CI, 1.92-2.81]) were associated with increased mortality. Conditional 1-year mortality was less than 20% regardless of number or severity of recent PICU-CIEs. Among children with high-risk PICU-CIEs, 1-year conditional survival decreased from 90% (95% CI, 89%-91%) after the first PICU-CIE to 81% (95% CI, 77%-86%) after the fourth PICU-CIE.

Conclusions and Relevance

This cohort study of children with SNI demonstrated a modest dose-dependent association between PICU-CIEs and short-term mortality. These data did not support the conventional wisdom that recurrent PICU admissions are associated with subsequent high mortality risk.

A Co-Designed Online Education Resource on Gastrostomy Feeding for Parents and Caregivers to Support Clinical Care

OBJECTIVE

Children with complex needs and severe disability may undergo gastrostomy insertion to support feeding difficulties. Parent education programs are critical components of clinical care pathways but there is little information on parent-reported educational needs. This study describes the collaborative process that yielded a resource to assist parents considering gastrostomy tube placement for their children, and the evaluation of the resource.

METHODS

A qualitative descriptive study was conducted to identify parent needs for gastrostomy education. Based on these data and codesigning with parents with a child with gastrostomy tube, an online resource comprising video and written materials was developed. Twenty parents then evaluated its suitability for parent learning.

RESULTS

Data describing parent needs were coded into categories which represented the gastrostomy "journey"-Decision Making, Hospital Stay and Living with Gastrostomy. Called Nourish , the gastrostomy training resource comprised 19 videos and 18 accompanying worksheets. Twenty parent caregivers rated it highly for its support for learning, confidence building, and planning.

CONCLUSION

The process that created Nourish generated a useful resource for parents considering or managing gastrostomy tube feedings for their child. Positive feedback suggests that this approach could be a valuable adjunct to clinical care.

Rate of paediatric gastrostomy insertion in England and relationship to epidemiology of cerebral palsy

Background and objectives

Gastrostomy tubes are commonly used to provide an alternative route for enteral nutrition. Most of the gastrostomies are inserted in children with cerebral palsy. Previous studies have shown an increase in insertion rate, however, epidemiological studies reveal a stasis in prevalence of cerebral palsy. We aimed to provide an up-to-date rate of gastrostomy insertion in children in England over a 20-year period and systematically review the prevalence of cerebral palsy to ascertain an epidemiological explanation for insertion trends.

Methods

Retrospective search of Hospital Episode Statistic, a database held diagnosis and procedural code from all England National Health Service hospitals from 2000 to 2021 using International Classification of Disease-10 and Office of Population Censuses and Survey's Classification-4. England Office for National Statistics data were used for population census. MEDLINE and EMBASE were systematically searched for epidemiology of cerebral palsy.

Results

There were 23 079 gastrostomies inserted in children <15 years in England (2000-2021) leading to a frequency of 12.4 insertions per 100 000 children per year and 1383 gastrostomy insertions in 15-18 years age group (6 per 100 000). The overall gastrostomy insertion rate in children <15 years has increased from 3.7 procedures per 100 000 in 2000 to 18.3 per 100 000 in 2017. Prevalence of cerebral palsy remained stable (1.5-3.3 per 1000 birth) since 1985.

Conclusions

There was a significant increase in the rate of gastrostomy insertion in children in England during most of the last 20 years not explained by a stable prevalence of cerebral palsy.

Comparison of Home-Blenderized Formula and Commercial Enteral Formulas for Gastrostomy Tube-Fed Children: A Retrospective, Prospective Cohort Study

Background Blenderized gastrostomy tube feedings (BGTFs) consist of pureed table foods and liquids that are administered as enteral tube feedings. Compared to commercial enteral formulas (CEFs), BGTF has been shown to have fewer side effects. Despite these results, apprehensions have been raised about microbial contamination, nutritional deficiencies or surplus, risk of gastrostomy tube (GT) blockages, and lack of consistency in clinical outcomes. The goal of this retrospective, prospective, 18-month-long study is to report the clinical and nutritional outcomes of GT-dependent pediatric patients who attended a multidisciplinary feeding clinic. Methodology After Institutional Review Board (IRB) approval and consent were obtained, 25 children who were receiving tube feeding via G were enrolled in a retrospective, prospective, observational, cohort study from August 2019 to February 2021. A multidisciplinary team was formed, and multivariate logistic regression was performed comparing subjects on BGTF versus CEF, per os diet versus nil per os, CEF versus homemade blenderized tube feeding (HBTF) versus blenderized tube feeding (BTF), and how they compared at the beginning and end of the study. Results The mean age of the patients was 4.4 years (SD ±2.2). Gastroesophageal reflux disease (GERD) and short bowel syndrome (SBS) were the most common comorbid gastrointestinal (GI) conditions. Of the 25 patients enrolled in the study, seven were initially on BGTF, while 14 ended the study on BGTF. There were no statistically significant differences in malnutrition status, feeding intolerance, emergency room visits, hospitalizations, and GT blockages between all different comparison groups when comparing between the CEF versus HBTF versus commercial blenderized tube feeding (CBTF) groups. Of the patients who were in the BGTF group, there was a resolution of vitamin A deficiency, vitamin D deficiency, and anemia (n = 1). In total, two patients had resolved vitamin deficiencies, namely, vitamins A and D. Conclusions When comparing BGTF and CEF, there was no statistically significant difference in outcomes. This study suggests that BGTF is at least equivalent to CEF in clinical outcomes, meaning BGTF should be considered standard nutrition for GT-dependent patients.

A Comparison Between the Complications of Laparoscopic and Open Gastrostomy Tube Insertions: A Single-Center Study From Riyadh, Saudi Arabia

Background and objective Gastrostomy is a procedure that involves placing a feeding tube through the abdominal wall into the stomach to provide nutritional support. There are several modes of gastrostomy tube insertion including laparoscopic-assisted gastrostomy (LAG), percutaneous endoscopic gastrostomy (PEG), and open gastrostomy (OG) procedure, among others. Although it is a widely performed procedure, limited data is available regarding gastrostomy in Saudi Arabia, specifically among the pediatric population. This study aimed to shed more light on different aspects of surgical gastrostomy procedures among pediatric patients at the King Abdullah Specialist Children's Hospital (KASCH) in Riyadh, Saudi Arabia. The main objective of our study was to report the indications and complications of both LAG and OG insertions in the pediatric population. Methods A retrospective cross-sectional study was conducted at KASCH to analyze the different parameters related to LAG and OG insertions, and to evaluate for any association between these modes of insertion and their complications. Pertinent data on children from birth to 14 years of age were collected through consecutive sampling using a chart review. A total of 107 pediatric patients who underwent the procedure from 2016 to 2020 were evaluated. Results Demographically, the majority (58%) of gastrostomies were performed in infants (less than a year old). Additionally, our study showed a significantly increased association between LAG and complications such as discharge, (27.12%), skin manifestations (27.12%), and bleeding (10.17%) when compared to OG. Conclusion Based on our findings, LAG showed less favorable outcomes in contrast to OG. Further studies should be conducted to validate our findings and ensure consistent results and outcomes among different methods of gastrostomy tube insertion.

Gastrostomy and congenital anomalies: a European population-based study

OBJECTIVE

To report and compare the proportion of children with and without congenital anomalies undergoing gastrostomy for tube feeding in their first 5 years.

METHODS

A European, population-based data-linkage cohort study (EUROlinkCAT). Children up to 5 years of age registered in nine EUROCAT registries (national and regional) in six countries and children without congenital anomalies (reference children) living in the same geographical areas were included. Data on hospitalisation and surgical procedures for all children were obtained by electronic linkage to hospital databases.

RESULTS

The study included 91 504 EUROCAT children and 1 960 272 reference children. Overall, 1200 (1.3%, 95% CI 1.2% to 1.6%) EUROCAT children and 374 (0.016%, 95% CI 0.009% to 0.026%) reference children had a surgical code for gastrostomy within the first 5 years of life. There were geographical variations across Europe with higher rates in Northern Europe compared with Southern Europe. Around one in four children with Cornelia de Lange syndrome and Wolf-Hirschhorn syndrome had a gastrostomy. Among children with structural anomalies, those with oesophageal atresia had the highest proportion of gastrostomy (15.9%).

CONCLUSIONS

This study including almost 2 million reference children in Europe found that only 0.016% of these children had a surgery code for gastrostomy before age 5 years. The children with congenital anomalies were on average 80 times more likely to need a gastrostomy before age 5 years than children without congenital anomalies. More than two-thirds of gastrostomy procedures performed within the first 5 years of life were in children with congenital anomalies.

Numbers, characteristics, and medical complexity of children with life-limiting conditions reaching age of transition to adult care in England: a repeated cross-sectional study [version 1; peer review: 2 approved]

Background

The number of children with life-limiting conditions in England is known to be increasing, which has been attributed in part to increased survival times. Consequently, more of these young people will reach ages at which they start transitioning to adult healthcare (14-19 years). However, no research exists that quantifies the number of young people with life-limiting conditions in England reaching transition ages or their medical complexity, both essential data for good service planning.

Methods

National hospital data in England (Hospital Episode Statistics) from NHS Digital were used to identify the number of young people aged 14-19 years from 2012/13 to 2018/19 with life-limiting conditions diagnosed in childhood. The data were assessed for indicators of medical complexity: number of conditions, number of main specialties of consultants involved, number of hospital admissions and Accident & Emergency Department visits, length of stay, bed days and technology dependence (gastrostomies, tracheostomies). Overlap between measures of complexity was assessed.

Results

The number of young people with life-limiting conditions has increased rapidly over the study period, from 20363 in 2012/13 to 34307 in 2018/19. There was evidence for increased complexity regarding the number of conditions and number of distinct main specialties of consultants involved in care, but limited evidence of increases in average healthcare use per person or increased technology dependence. The increasing size of the group meant that healthcare use increased overall. There was limited overlap between measures of medical complexity.

Conclusions

The number of young people with life-limiting conditions reaching ages at which transition to adult healthcare should take place is increasing rapidly. Healthcare providers will need to allocate resources to deal with increasing healthcare demands and greater complexity. The transition to adult healthcare must be managed well to limit impacts on healthcare resource use and improve experiences for young people and their families.

Outcomes for gastrostomy-fed children and their parents: qualitative findings from the 'Your Tube' study

AIM

To identify child and parent outcomes relevant to having a gastrostomy, and to specify outcomes believed to be particularly salient to type of diet (formula vs blended food).

METHOD

Twenty parents, two children (both 12y), and 41 professionals (dietitians [n=10]; nurses [n=12]; paediatricians [n=12]; speech and language therapists [n=7)]) were recruited. Parents and children were interviewed; professionals participated in focus groups. Children (2-18y) represented included those on formula (n=11), blended-food (n=7), and mixed (n=2) diets. All had been tube-fed for at least 6 months. Neurological, genetic, and metabolic conditions were represented.

RESULTS

Participants identified a range of children's outcomes relevant to a gastrostomy, including physical health, gastrointestinal symptoms, sleep, and time spent feeding. The children described experiences of exclusion caused by being tube-fed. Time, sleep, and emotional health were regarded as most salient to understanding parents' gastrostomy outcomes. Participants believed type of diet would most likely effect gastrointestinal symptoms, time spent feeding, sleep, and physical health.

INTERPRETATION

Findings indicate a number of refinements to, and allow further specification of, the current 'initial' core outcome set for tube-fed children. Findings also have implications for choice of outcomes measures. Further qualitative research with children and young people is needed. What this paper adds Sleep is a key outcome for children and parents. Gastrointestinal symptoms and physical health were regarded as outcomes most likely to be affected by type of diet. Well-being and participation were identified as key distal outcomes. Gastrostomies are complex interventions. Further specification of the core outcome set is possible.

Point Prevalence of Gastrostomy in a Paediatric Population

OBJECTIVE

The aim of the study was to determine the prevalence of gastrostomy in a paediatric population.

METHODS

A population-based cross-sectional point prevalence study of paediatric gastrostomy was performed. Patients included were ages 0 to 19 years, living within 3 inner-city London boroughs; Southwark, Lambeth, and Lewisham. Patients were identified as having a gastrostomy in situ via Home Enteral Nutrition (HEN) and community nursing databases. Electronic healthcare records were scrutinised to confirm current use of a gastrostomy. The main outcome measures were the point prevalence of gastrostomy in the paediatric population (gastrostomies/100,000 children), primary diagnosis, indication underlying gastrostomy insertion, and age at insertion.

RESULTS

The total population studied was 946,709, of whom 213,920 were of age 0 to 19 years. Of these, 179 had a gastrostomy in situ giving a point prevalence for gastrostomy in the paediatric population of 83.7 (95% confidence interval [CI]: 71.4-96.0)/100,000 children. This varied between age groups: 0 to 4 years: 79.6 (57.3-102.0)/100,000, 5 to 9 years: 116.3 (88.7-143.9)/100,000, 10 to 14: years 87.9 (61.9-113.9)/100,000 and 15 to 19: years 41.4 (22.1-60.1)/100,000. The most common primary diagnoses were neurological disorders (57.1%), and structural abnormalities (16.2%). Unsafe swallow was the most common indication (61%), followed by nutritional or fluid supplementation (28.6%), and behavioural reasons (8.7%). The majority (85.1%) of gastrostomies were inserted under the age of 2 years.

CONCLUSIONS

This is the first UK population-based study of paediatric gastrostomy, identifying a point prevalence of 84/100,000 children. The peak prevalence is in children ages 5 to 9 years. Gastrostomy insertion after a child reaches school age is uncommon.

Outcomes and Safety of Blenderized Tube Feedings in Pediatric Patients: A Single Center's Experience

INTRODUCTION

Recently, significant interest from families and healthcare providers has arisen to use blenderized tube feedings (BTF). Although many institutions are providing this nutritional option, literature documenting outcomes and safety is lacking.

METHODS

A retrospective chart review was performed on pediatric patients receiving BTF at Rutgers-Robert Wood Johnson University Hospital between January 2013 and April 2017. Demographic data and dietary information before and after BTF were collected. Reasons for diet initiation, symptoms, and anthropometrics were recorded. Adverse events and outcomes were assessed through physician documentation and relevant medication changes.

RESULTS

Thirty-five patients (24 boys) received BTF. Age at initiation of BTF ranged from 1 to 19 years (mean 8.3 +/- 5.8 [SD] years). Length of follow-up ranged from 1 to 45 months (mean 15 +/- 12.2 months). The most common reason for starting BTF was gastroesophageal reflux disease (GERD) (N = 32). Almost all patients were on medications for GERD, constipation, or gastrointestinal dysmotility before starting BTF (N = 33). Majority of patients had improvement in relevant symptoms (N = 20); 13 of 33 patients on gastrointestinal medications were able to wean or stop medication(s). BMI z scores did not differ before and after BTF initiation (P = 0.558). No serious life-threatening adverse events were found.

CONCLUSIONS

Our data suggest that BTF is a safe dietary intervention that may improve gastrointestinal symptoms in pediatric patients. Further prospective studies are needed to compare safety and efficacy of BTF and commercial formulas in pediatric patients.

Survival of children and adolescents with intellectual disability following gastrostomy insertion

BACKGROUND

Positive health outcomes have been observed following gastrostomy insertion in children with intellectual disability, which is being increasingly used at younger ages to improve nutritional intake. This study investigated the effect of gastrostomy insertion on survival of children with severe intellectual disability.

METHODS

We used linked disability and health data of children and adolescents who were born in Western Australia between 1983 and 2009 to compare survival of individuals with severe intellectual disability by exposure to gastrostomy status. For those born in 2000-2009, we employed propensity score matching to adjust for confounding by indication. Effect of gastrostomy insertion on survival was compared by pertinent health and sociodemographic risk factors.

RESULTS

Compared with children born in the 1980s-1990s, probability of survival following first gastrostomy insertion for those born in 2000-2009 was higher (2 years: 94% vs. 83%). Mortality risk was higher in cases than that in their matched controls (hazard ratio 2.9, 95% confidence interval 1.1, 7.3). The relative risk of mortality (gastrostomy vs. non-gastrostomy) may have differed by sex, birthweight and time at first gastrostomy insertion. Respiratory conditions were a common immediate or underlying cause of death among all children, particularly among those undergoing gastrostomy insertion.

CONCLUSIONS

Whilst gastrostomy insertion was associated with lower survival rates than children without gastrostomy, survival improved with time, and gastrostomy afforded some protection for the more vulnerable groups, and earlier use appears beneficial to survival. Specific clinical data that may be used to prioritise the need for gastrostomy insertion may be responsible for the survival differences observed.

Risk of Hospitalizations Following Gastrostomy in Children with Intellectual Disability

OBJECTIVE

To examine the frequency of hospital admissions before and after gastrostomy insertion in children with severe intellectual disability.

STUDY DESIGN

We conducted a retrospective cohort study using linked health administrative and disability data from Western Australia (WA) and New South Wales (NSW). Children born between 1983 and 2009 in WA and 2002 and 2010 in NSW who had a gastrostomy insertion performed (n = 673 [WA, n = 325; NSW, n = 348]) by the end of 2014 (WA) and 2015 (NSW) were included. Conditional Poisson regression models were used to evaluate the age-adjusted effect of gastrostomy insertion on acute hospitalizations for all-cause, acute lower respiratory tract infections (LRTI), and epilepsy admissions.

RESULTS

The incidence of all-cause hospitalizations declined at 5 years after procedure (WA cohort 1983-2009: incidence rate ratio, 0.70 [95% CI, 0.60-0.80]; WA and NSW cohort 2002-2010: incidence rate ratio, 0.63 [95% CI, 0.45-0.86]). Admissions for acute LRTI increased in the WA cohort and remained similar in the combined cohort. Admissions for epilepsy decreased 4 years after gastrostomy in the WA cohort and were generally lower in the combined cohort. Fundoplication seemed to decrease the relative incidence of acute LRTI admissions in the combined cohort.

CONCLUSIONS

Gastrostomy was associated with health benefits including reduced all-cause and epilepsy hospitalizations, but was not protective against acute LRTI. These decreases in hospitalizations may reflect improved delivery of nutrition and medications.

Data Linkage: Canadian and Australian Perspectives on a Valuable Methodology for Intellectual and Developmental Disability Research

Data linkage holds great promise for generating new information about people with intellectual and developmental disabilities (IDD) as a population, yet few centers have developed the infrastructure to utilize this methodology. Two examples, from Canada and Australia, describe their efforts in building data linkage capabilities, and how linked databases can be used to identify persons with IDD and used for population-based research. The value of data linkage is illustrated through new estimates of prevalence of IDD; health service utilization patterns; associations with sociodemographic characteristics, and with physical and mental health conditions (e.g., chronic diseases, injury, fertility, and depression); and findings on equity in medical treatments. Examples are provided of findings used for governmental policy and program planning.
