Informal Caregiving: Health System Cost Implications

Area of Science:

• Health Economics
• Public Health
• Gerontology

Background:

• Informal caregiving is often viewed as a cost-saving measure for healthcare systems.
• However, caregiving can negatively affect caregiver health, potentially increasing their healthcare utilization and costs.
• This study investigates the net economic impact of informal caregiving on healthcare expenditures.

Purpose of the Study:

• To examine the impact of informal caregiving on the costs of publicly funded healthcare services in Ontario, Canada.
• To compare the healthcare costs of informal caregivers with those of non-caregivers.

Main Methods:

• Utilized data from the 2008/09 Canadian Community Health Survey-Healthy Aging Supplement, linked to administrative health databases.
• Employed a difference-in-differences design to analyze changes in total healthcare costs 1-2 years before and after the caregiving start date.
• Generalized Linear Models were used to estimate total healthcare costs.

Main Results:

• The study included 4275 participants (1265 caregivers, 3010 non-caregivers).
• While healthcare utilization increased over time for both groups, the increase was less pronounced for caregivers.
• Adjusted total healthcare costs for caregivers were 11.32% lower than for non-caregivers two years post-caregiving onset.

Conclusions:

• Findings suggest that informal caregiving may lead to reduced public healthcare costs.
• Highlights a critical gap in data collection and caregiver identification within policy and research.
• Emphasizes the need for longitudinal research on caregivers' objective health outcomes.
