Unwarranted Clinical Variation Resources

Clinical variation occurs across all disciplines and practices and arises for a range of reasons including: complexity of a patient's illness; burden of illness in different populations; local innovations; administrative variation such as inconsistent coding; and 'local' explanations such as workforce issues.

Unwarranted Clinical Variation (UCV) is defined as "variation that cannot be explained by the condition or the preference of the patient; it is variation that can only be explained by differences in health system performance" (ACSQSH).
