Mean Abnormal Result Rate

Mean Abnormal Result Rate: Proof of Concept of a New Metric for Benchmarking Selectivity in Laboratory Test Ordering.

OBJECTIVES There is a need to develop and validate new metrics to access the appropriateness of laboratory test requests. METHODS The mean abnormal result rate (MARR) is a proposed measure of ordering selectivity, the premise being that higher mean abnormal rates represent more selective test ordering. As a validation of this metric, we compared the abnormal rate of lab tests with the number ...

Is abnormal adrenergic activation associated with abnormal Heart Rate Recovery?

BACKGROUND Heart Rate Recovery (HRR) reflects the capacity of the cardiovascular system to reverse the vagal withdrawal caused by exercise. Scintigraphy with metaiodobenzylguanidine (I(123) MIBG) evaluates innervation and cardiac adrenergic activation. The association of these two methods is not well established. OBJECTIVE To evaluate the association between HRR and washout rate (WO) of I(123...
