The package of health system resilience indicators serves as a dedicated resource to measure and monitor health system resilience in routine operations as well as in the context of disruptive shocks and stressors. This work addresses an identified gap in measurement and monitoring of health system resilience. It complements the Health Systems Resilience Toolkit and supports implementation of the recommendations in WHO’s position paper on building health system resilience for UHC and health security. The package aims to support countries to progressively build their capacities to measure, monitor and build health system resilience from national to subnational levels covering health facilities and other service delivery platforms. It emphasizes an integrated approach to health system strengthening underpinned by essential public health functions, encompassing health emergency preparedness. It includes: - guidance on how to utilize and adapt the health system resilience indicators, including a step-by-step guide - a suite of recommended health system resilience indicators with technical specifications - supplementary indicators of relevance to health system resilience The primary target audience for this package is national and subnational health authorities (including planners and managers) and service providers, as well as local, regional, and global technical organizations and partners working on health system strengthening, including WHO, United Nations country teams, donors, nongovernment organizations, development and humanitarian agencies, and other health-related technical agencies.
