Aim 4: Health System Research
Widening ONDRI’s lens of research
As the population ages, the number of people living with neurodegenerative disease, stroke and dementia is expected to dramatically rise in Ontario and throughout the world.
The goal of Aim 4 is to analyze Ontario health system records, to inform healthcare policy and planning for the people living with the diseases studied by ONDRI.

Broad health system perspective examining real world data
ONDRI’s Aim 4 is led by expert researchers from ICES (formerly the Institute for Clinical Evaluative Sciences), an independent not-for-profit research institute funded by the Ontario Ministry of Health.
ICES provides expertise in health services research to inform policy makers and stakeholders. Under Ontario’s privacy legislation, ICES is permitted to collect & store health data for health research purposes. Examples of such data include hospitalizations, emergency department visits, drugs dispensed under the provincial formulary for those age 65+.
Varied research topics
Aim 4 researchers use anonymized ICES health data to better understand how people living with neurodegenerative diseases, stroke and dementia use publicly funded health services, on a provincial scale. Aim 4’s work helps inform health system policy and resource planning.
Aim 4 research is focused in four areas:
- Health system use and cost of neurodegenerative disease, stroke and dementia
- The burden of other, co-occurring health conditions amongst people living with neurodegenerative disease, stroke and dementia
- Patterns of drug therapy in people living with neurodegenerative disease, stroke and dementia
- Securely linking existing Ontario health data to varied data sources (e.g. electronic medical records)
The impact of Aim 4 research on the health system
Aim 4 researchers have published findings in diverse areas, with many more studies planned.
Publications to date include:
- Sex differences in patterns of potentially inappropriate medication use at nursing home admission among people with dementia
- Trajectories of health care use among people living with dementia
- Role of drugs used in other diseases as potential treatments for Parkinson’s disease
- Sex differences in care needs for stroke survivors who are admitted to nursing homes
