Population level administrative data evidence of visits to the emergency department by youth with intellectual/developmental disabilities in BC, Canada.

INTRODUCTION: The literature indicates that youth with intellectual/developmental disabilities (IDD) have poor health and that access to health services decreases as they transition from pediatric to adult services. At the same time their use of emergency department services increases. The objective of this study was to compare use of emergency department services by youth with IDD to youth without IDD, with particular emphasis on the transition period from pediatric to adult health care services. METHODS: This research used a population level administrative health data base for the province of British Columbia Canada for 2010-2019 to examine the use of emergency departments by youth with IDD (N = 20,591) compared to a population group of youth without IDD (N = 1,293,791). Using the ten years of data, odds ratios for visits to the emergency department were calculated adjusting for sex, income and geographical area within the Province. In addition, difference-in-differences analyses were calculated for age matched subsets of the two cohorts. RESULTS: Over the ten year period, 40.60% of youth with IDD visited an emergency department at least once, compared to 29.10% of youth without IDD. Youth with IDD had an odds ratio of visiting an emergency department 1.697 (1.649, 1.747) times that of youth without IDD. However, when odds were adjusted for a diagnosis of either psychotic illness or anxiety/depression, the odds for youth with IDD visiting emergency compared to youth without IDD were reduced to 1.063 (1.031, 1.096). Use of emergency services increased as youth aged. Type of IDD also affected use of emergency services. Youth with Fetal Alcohol Syndrome had the greatest odds of using emergency services compared to youth with other types of IDD. DISCUSSION: The findings from this study indicate that youth with IDD have higher odds of using emergency services than youth without IDD although these increased odds appear to be largely driven by mental illness. In addition, use of emergency services increases as the youth age and transition from pediatric to adult health services. Better treatment of mental health issues within this population may reduce their use of emergency services.

The Use of Medically Required Dental Services by Youth with Intellectual/Developmental Disabilities in British Columbia, Canada.

INTRODUCTION: The literature indicates that youth with intellectual/developmental disabilities (IDD), such as Down syndrome or autism, have poor oral health. A number of factors influence their oral health, including the use of medically required dental treatments. METHODS: This paper describes the first use of population-level administrative health data to examine the use of medically required dental services by youth with IDD compared with youth without IDD in Canada. RESULTS: Youth with IDD had 4-9 times the odds of a medically required dental treatment compared with youth without IDD. Odds varied with age and type of IDD. CONCLUSIONS: Youth with IDD used medically required dental services to a greater extent than youth without IDD. Use of medically required dental treatments by youth with IDD declined with age; this may indicate greater difficulty accessing services when youth transition from pediatric to adult services. These findings provide baseline information on the use of medically required dental treatments and can contribute to future assessments of dental services for youth with IDD.

Population Level Mental Health Diagnoses for Youth with Intellectual/Developmental Disabilities Compared to Youth without Intellectual/Developmental Disabilities.

There is evidence in the literature that youth with intellectual/developmental disabilities (IDD) experience mental health issues to a greater extent compared to youth without IDD. In addition, transition from pediatric to adult services may be a period of increased anxiety and mental health problems for these youth. This study used a retrospective cohort design using population level administrative health data to compare mental health diagnoses between youth with IDD and youth without IDD; particularly examining the period when youth transition from pediatric health services to adult health services. In addition, this study compared the mental health of youth with various types of IDD (Down syndrome, autism, fetal alcohol syndrome and other rarer diagnoses). Results showed that at the population level youth with IDD have greater odds of anxiety/depression or psychotic illness than youth without IDD. Adjusted odds of anxiety/depression or psychotic illness also varied with age, income level, sex, and type of IDD. Youth with fetal alcohol syndrome had the greatest odds of both anxiety/depression and a psychotic illness. Odds of anxiety/depression increased from age 15-19 years old. Odds of a psychotic illness increased from age 15 to age 24 years old.

Prescriptions for Antipsychotics: Youth with Intellectual/Developmental Disabilities Compared to Youth without Intellectual/Developmental Disabilities.

PURPOSE: The purpose of this study was to compare antipsychotic use by youth with intellectual/developmental disabilities to youth without IDD as they transitioned from pediatric to adult health care services. In addition, antipsychotic use was compared between youth with different types of IDD (autism, Fetal Alcohol Syndrome, Down syndrome and 'other'). METHODS: Population level administrative health data was used to compare the dispensing of antipsychotics for youth aged 15 to 24 years with and without IDD, between 2010 and 2019. Because antipsychotics are associated with metabolic syndrome and type 2 diabetes, we also examined the dispensing data for metformin. In addition, we examined dispensed antipsychotics between different types of IDD. For both dispensing of antipsychotics and metformin, we used multi-variable logistic regression to derive adjusted odds ratios. RESULTS: There were 20,591 youth with IDD and 1,293,791 youth without IDD. Youth with IDD had significantly higher odds of being dispensed an antipsychotic (7.13 (6.82, 7.44)), even when a diagnosis of a psychotic illness was included in the regression. Higher odds were found in all age groups. Youth with IDD also had significantly higher odds of being dispensed metformin (3.739 (3.323, 4.208)) compared to youth without IDD. Youth with autism, FAS and 'other' types of IDD diagnoses all had higher odds of being dispensed an antipsychotic compared to youth with Down syndrome. CONCLUSION: Compared to youth without IDD, youth with IDD were more frequently dispensed antipsychotics and metformin. These findings have important implications for the health of youth with IDD.

Population-level use of gynecological health services by female youth with intellectual/developmental disabilities in British Columbia Canada.

BACKGROUND: There is evidence that female youth with intellectual/developmental disabilities (IDD) experience poorer gynecological care compared to female youth without disabilities. OBJECTIVE: The objective of this study was to obtain baseline data on visits to a health care provider for a gynecological issue for females with IDD and compare that information to the experiences of female youth without IDD. METHODS: This study is a retrospective cohort study using population-level administrative health data from 2010 to 2019 for females aged 15-24 years, with and without IDD. RESULTS: 6452 female youth with IDD and 637,627 female youth without IDD were identified in the data. Over the ten-year period, 53.77% of youth with IDD and 53.68% of youth without IDD had a visit to a physician for a gynecological issue. However, as females with IDD aged, the number of people seeing a physician for a gynecological issue decreased. In the group aged 20-24 years, 15.25% of females with IDD and 24.47% of females without IDD (p < 0.0001) had a Pap test done at any time; 25.94% of females with IDD had a visit for contraception management and 28.38% of females (p < 0.0001) without IDD had a visit for contraception management. Gynecological care also varied by type of IDD. CONCLUSIONS: Females with IDD had a similar number of visits for a gynecological issue as female youth without IDD. However, the reasons for visits and the age at which visits occurred differed between youth with and without IDD. As females with IDD transition into adulthood, gynecological care must be maintained and improved.

Mental health outcomes among parents of a child who has a developmental disability: Comparing different types of developmental disability.

BACKGROUND: There is very little information on the effects of different types of developmental disability on the mental health of parents of children who have a DD. OBJECTIVE: This paper compared the mental health of parents of children with Autism Spectrum Disorder (ASD), Down syndrome, Fetal Alcohol Syndrome (FAS) and other types of DD. METHODS: A cross-sectional design was used to examine population-level administrative health data for mental health outcomes in cohorts of fathers and mothers of children with four different types of a DD. As well as type of DD, additional variables were examined, these included: sex of the parent, age of the parent at birth of the child with the DD, income, sex of the child with the DD, number of children in the family and place of residence. RESULTS: For both fathers and mothers odds of a diagnosis of depression or another mental health problem were associated with type of DD. Parents of children with FAS experienced the greatest odds of a depression or other mental health diagnosis. Odds of a diagnosis for fathers were associated with low income. Odds of a diagnosis for mothers were associated with the sex of the child with the DD. CONCLUSIONS: These findings are important for understanding families which include a child with a DD, as a guide for future research, and for developing effective programs and services for these parents.

Using administrative data to examine variables affecting the mental health of siblings of children who have a developmental disability.

BACKGROUND: There is evidence that siblings of children with a developmental disability (DD) experience poorer mental health outcomes and increased stress compared to siblings of non-disabled children. The variables which contribute to this are unclear. AIMS: This study was designed to examine population-level and individual variables associated with differences in mental health outcomes among siblings of children who have a variety of developmental disabilities. METHODS: Population-level administrative health data covering 1985-2014 for the province of British Columbia, Canada were used to develop a cohort of over 45,000 children who have a sibling with a DD. Individual-level, demographic and health care services variables were used in logistic regression to assess their relationship to diagnoses of depression or other mental health problems. OUTCOMES: Odds of a diagnosis of depression or a mental health problem other than depression were associated with sex of the non-disabled sibling, sex of the child with the developmental disability, type of disability, birth order and income. CONCLUSIONS: Type of developmental disability, and characteristics of the non-disabled sibling and their family are associated with mental health outcomes of siblings of children with a DD.

Mental health of parents of children with a developmental disability in British Columbia, Canada.

BACKGROUND: There is evidence in the literature that parents of children who have a developmental disability experience an increased risk of mental health problems. METHODS: This study used population-level administrative data from the Ministry of Health, British Columbia, Canada, to assess the mental health of parents of children who have a developmental disability compared with the mental health of parents of children who do not have a developmental disability. Population-level and individual explanatory variables available in the data were included in the models. RESULTS: At a population level, the study found strong evidence that parents of children who have a developmental disability experience higher odds of depression or other mental health diagnoses compared with parents of children who do not have a developmental disability. Age of the parent at birth of the child, income and location of healthcare services were all associated with outcomes. CONCLUSION: Parents of children who have a developmental disability may be in need of programmes and services that support their mental health.

A population-level study of the mental health of siblings of children who have a developmental disability.

This study used population level administrative data for health service utilization from the Ministry of Health, British Columbia, Canada to assess the mental health of siblings of children who have a developmental disability. At a population level, the study found strong evidence that siblings of children who have a developmental disability experience higher odds of a depression or other mental health diagnosis compared to siblings of children who do not have a developmental disability. In addition, there was evidence that in families with a child with a developmental disability, siblings who are diagnosed with depression or another mental health problem use physician and/or hospital services for these conditions to a greater extent than siblings who are diagnosed with depression or a mental health problem but do not have a family member with a developmental disability. Evidence of increased depression and mental health problems existed across all income levels, indicating that other stressors may have an impact. These findings suggest that siblings of children who have a developmental disability are a vulnerable group in need of programs and services that support their mental health.
