ICAR tools are used to systematically assess a health care facility’s IPC practices and guide quality improvement activities (e.g., by addressing identified gaps). CDC’s Infection Control Assessment and Response Toolkit is intended to help assess IPC practices in acute care, long-term care, and outpatient settings. The tool includes a series of modules that individuals performing the assessment may use depending on the focus of the assessment. Modules can be selected based on allotted time, facility-specific concerns, or applicability to an organism of concern.
