Avoiding Unnecessary Updates

Graph reduction underlies most implementations of lazy functional languages, allowing separate computations to share results when sub-terms are evaluated. Once a term is evaluated, the node of the graph representing the computation is updated with the value of the term. However , in many cases, no other computation requires this value, so the update is unnecessary. In this paper we take some st...

Reducing unnecessary inpatient laboratory testing in a teaching hospital.

After an inpatient phlebotomy-laboratory test request audit for 2 general inpatient wards identified 5 tests commonly ordered on a recurring basis, a multidisciplinary committee developed a proposal to minimize unnecessary phlebotomies and laboratory tests by reconfiguring the electronic order function to limit phlebotomy-laboratory test requests to occur singly or to recur within one 24-hour w...

Repeat testing of critical laboratory test results.

To the Editor.—Recent literature has explored the value of repeat testing of alert or critical laboratory test results, as illustrated in the article by Toll et al. Using a large data set for selected tests, that article makes the point that repeat testing is rarely of value. All too often, laboratories retest results that are considered ‘‘critical’’ because of a purely emotional desire to avoi...
