Health and Health Care Outcomes
What is the issue?
Previous work from H-CARDD has shown that Ontario adults with developmental disabilities have poorer physical and mental health and use more health care services than other adults. Specific subgroups, such as younger or older adults, or adults with additional mental health or addiction issues, have unique health concerns. However, our work to date has tended to operate in silos. This means that we don’t often look at patterns across groups and health outcomes, and therefore solutions cannot be integrated across perspectives and settings.
How is H-CARDD helping?
This project takes an integrated, cross-sectoral approach to study five concerning health and health care outcomes:
- 30-day repeat emergency department visits
- 30-day repeat hospitalizations
- alternative level of care days in hospital
- long-term care stays
- premature mortality
We followed a cohort of nearly 65,000 Ontarian adults with developmental disabilities, who were between 19 and 65 years of age in 2010, for a six-year period between April 2010 and March 2016. We compared this cohort to a group of adults without developmental disabilities and examined these outcomes by age, sex and neighbourhood income, as well as by the type of developmental disability they had.
Our main finding is that adults with developmental disabilities were disadvantaged for every outcome examined compared to adults without developmental disabilities. The report below illustrates these health care patterns by different subgroups and by Ontario region. With these results in hand, H-CARDD will continue to work together with scientists, clinicians, advocates and policy-makers to design and implement integrated solutions that can bridge silos of care between hospital and community, and between various sectors supporting this population.
