Evaluating STAT Testing Alternatives by Calculating Annual Laboratory Costs: The Calculating Annual Laboratory Costs Model (CALC) (Part 1)

Evaluating STAT Testing Alternatives by Calculating Annual Laboratory Costs: The Calculating Annual Laboratory Costs Model (CALC) (Part 1)To identify which of two or more testing configurations is most cost-effective, laboratory managers need an all-encompassing assessment tool. The Calculating Annual Laboratory Costs (CALC) technique has been developed to provide a method for comparing costs of identical testing services from alternative testing configurations. cialis professional 20 mg The process of comparing the costs using the CALC technique involves the following:
Define the Settings
Identify the site locations and/or equipment configurations, the tests which are to be offered, and the number of samples expected to be processed. If one alternative offers more tests or processes more samples than the other, use only the costs attributable to those tests provided by both configurations.
There are several reasons that may prompt this comparison. A hospital may expand the number of beds by building a new intensive care unit, thus increasing the overall testing load beyond the capabilities of the central laboratory. To meet this expanded need, alternative configurations, either a stat lab or bedside testing, could be considered. There are other situations wherein new testing configurations may be considered simply to reduce turnaround times.
In the example shown (Table 1), the cost of providing testing to an intensive care unit with a new stat lab is compared with the cost of providing testing with an automated bedside analyzer. It is assumed that 50 test profiles will be performed each day, including Po2, Pco2, pH, K+, Ca+ +, Na+, and hematocrit.
