Final answer:
Measurement of variation in health care and its application to quality improvement requires identifying what needs to be measured, understanding true variation versus artifact or statistical error, and establishing a standard for comparison.
Step-by-step explanation:
The subject of this question is Health. Measurement of variation in health care and its application to quality improvement requires the identification and articulation of several factors.
Firstly, it is important to determine what is to be measured. This involves identifying the specific health care outcomes or processes that need to be evaluated.
Secondly, it is crucial to understand the concept of true variation versus artifact or statistical error. This means distinguishing between genuine differences in health outcomes and any errors or anomalies that may occur due to measurement or statistical methods.
Lastly, it is necessary to establish the standard against which the measured outcomes or processes will be compared. This refers to a benchmark or reference point that helps assess the quality and effectiveness of health care.
