Methods to assess the reliability of the interRAI Acute Care: a framework to guide clinimetric testing. Part II

The interRAI Acute Care is a comprehensive geriatric assessment tool that provides a holistic picture of complex and frail hospitalized older persons. It is designed to support holistic care planning and to transfer patient data across settings. Its usefulness in clinical decision making depends on the extent to which clinicians can rely on the patient data as accurate and meaningful indicators of patients functioning. But its multidimensional character implies challenges for clinimetric testing as some of the traditional analyses techniques cannot be unconditionally applied. The objective was to present an overview of methods to examine the reliability of the interRAI Acute Care. For each line of evidence, examples of hypotheses and research questions are listed.
