Final answer:
Readmissions can be found in HEDIS tools through the readmission rate measure.
Step-by-step explanation:
Readmissions can be found in HEDIS tools in the context of healthcare quality measurement and reporting. HEDIS (Healthcare Effectiveness Data and Information Set) is a set of performance measures developed by the National Committee for Quality Assurance (NCQA) to assess the quality of healthcare provided by health plans. One of the measures in HEDIS is the readmission rate, which measures the percentage of patients who are readmitted to the hospital within a certain timeframe after an initial hospitalization.
