Sources of Delays

•A: Tests not ordered or results no posted.

Sources of Delays

• A: Tests not ordered or results no posted were greatest cause of delays.

So let’s study why the tests are not being ordered or posted, right?

But… are all the tests necessary?


New Aim:

To reduce the number of preoperative tests performed so that only those which are important to the medical

mgmt of adult surgical pt during pre-op period are ordered.

Changes Identified


Changes Identified

• The perception was that anesthesiologists sometimes delay surgical cases in order to conduct further patient testing, with the results that surgeons have learned to order various tests simply as a precaution against such delays. The upshot is unnecessary testing.

Develop disease and surgical procedural

testing guidelines for:

-laboratory testing, -electrocardiography

-chest radiography

Cycles of Change• Guidelines developed• Dr. Higgins educated the

surgeons on the guidelines• Test ordering patterns were

monitored• Quarterly reports sent to

surgeons and to the specialty • Results amount to approximately

$200,000 annual cost savings.
