Article Synopsis
  • Cancer significantly impacts individuals with intellectual or developmental disabilities (IDD), but there is limited research on their survival rates compared to those without IDD.
  • A study in Ontario examined breast, colorectal, and lung cancer outcomes from 2007 to 2019, finding that people with IDD had much worse survival rates.
  • The results showed that cancer patients with IDD had over twice the risk of dying from all causes and from cancer itself compared to those without IDD, highlighting the need for targeted interventions to address these survival disparities.

Introduction: Emerging evidence suggests adults with intellectual and/or developmental disabilities (IDD) may be at risk of inequities in cancer experiences and outcomes. Individuals with IDD may experience multiple barriers that could worsen outcomes and experience. These barriers may be connected to features of IDD or the healthcare system overall.

Background: Access to high-quality primary care has been identified as a pressing need for adults with intellectual and developmental disabilities (IDD). Adults with IDD live with complex physical and mental health conditions, use health services differently than the general population and continue to face challenges when accessing health services. Interprofessional primary care teams offer comprehensive and coordinated approaches to primary care delivery and are well-positioned to address the needs of adults with IDD and other vulnerable populations.

Background: Study of frailty in adults with intellectual and developmental disabilities (IDD) is relatively new. To build the body of literature, an international consensus statement on how to support adults with IDD as they become frail was developed based on fictional cases. This study examined the face validity and applicability of the consensus statement to real-world care planning.

Article Synopsis
  • Administrative data has been commonly used in research to identify cases of Autism Spectrum Disorder (ASD), but prior studies lacked robust clinical validation.
  • A study involving nearly 8,670 children in British Columbia tested the accuracy of 11 algorithms for determining ASD status using linked health data, with clinical assessments as the gold standard.
  • The findings revealed that while some algorithms had high positive predictive values, they were still inadequate for reliably distinguishing ASD from other developmental disorders, highlighting a need for better validation studies in this area.

Introduction: There is increasing attention on the cancer burden for adults with intellectual and developmental disabilities (IDD). Emerging evidence suggests there are differences in cancer experiences and outcomes for individuals living with IDD, from risk through survivorship. These differences may be attributed to features of the IDD, such as cognitive deficits and communication, as well as social determinants of health-like lower education levels and ableism.

Objectives: To examine the impact of the dissemination of guidelines to physicians and of a population-level health communication intervention on the percentage of adults with intellectual and developmental disabilities (IDD) receiving preventive care through primary care.

Methods: Noninstitutionalized adults with IDD in the province of Ontario, Canada, aged 40 to 64 years were matched to Ontarians without such disabilities each fiscal year (FY) from 2003 to 2016. Health administrative data were used to create a composite measure of receipt of recommended preventive primary care.

Background: Frailty is an established predictor of admission into long-term care (LTC) and mortality in the elderly population. Assessment of frailty among adults with intellectual and developmental disabilities (IDD) using a generic frailty marker may not be as predictive, as some lifelong disabilities associated with IDD may be interpreted as a sign of frailty. This study set out to determine if adding the Home Care-Intellectual and Developmental Disabilities Frailty Index (HC-IDD Frailty Index), developed for use in home care users with IDD, to a basic list of predictors (age, sex, rural status, and the Johns Hopkins Frailty Marker) increases the ability to predict admission to long-term care or death within one year.

In the absence of complete public surveillance data, estimating the prevalence and needs of sub-groups of heterogeneous populations is nonetheless critical to properly inform health and social services planning and policy. We thus introduce market segmentation as an innovative tool for health and social services planners and policy makers. Segmentation is a process whereby broad populations are categorized into sub-groups with common characteristics and needs.
