RESUMEN
The Canadian Institutes of Health Research - Institute of Health Services and Policy Research's (IHSPR's) Strategic Plan 2021-2026: Accelerate Health Care System Transformation through Research to Achieve the Quadruple Aim and Health Equity for All (CIHR IHSPR 2021) outlines the Institute's key priority areas for investment and activity over the next five years. IHSPR used an evidence-informed strategic planning process that was pan-Canadian in scope and designed to elicit the health services and policy research priorities of decision makers, providers, researchers, patients, communities and the public. This paper outlines IHSPR's four key strategic priorities for supporting and optimizing research in transforming Canada's healthcare delivery systems over the next five years.
