More and more in this day and age, the laboratory is encouraged to reduce costs and streamline operations by using available resources in the most effective and efficient manner possible. One of the areas of the lab that is increasingly becoming a problem when it comes to cost reduction is the send out area. Since most labs can now perform the vast majority of their testing on automated chemistry and hematology analyzers, tests that must be performed at reference laboratories are increasingly esoteric, manual, and/or molecular diagnostic tests. And those tests are expensive.
As an example, my own lab sent out about 10 chromosomal microarray (CMA) tests in 2008; that number increased to 400 CMA tests in 2011 and is on track to be 865 in 2013. At $1400.00 each, the cost to the lab increased from $14,000 to $1.2 million over that time period. And that’s just one relatively inexpensive molecular diagnostic test. Some of the gene sequencing tests can run between $5000, and $10,000 per test.
Labs are trying a multitude of different schemes in order to try to curb these send out test costs. One method that is fairly effective is to have a “gatekeeper” – a person or persons who review and must approve every test that leaves the lab that costs over a pre-set amount. This particular method is probably one of the best for controlling send out costs, but it requires time and commitment on the part of the gatekeeper, and a willingness to interact with physicians who have ordered the tests that may be less than happy than someone is questioning their order.
Another method used for send out cost control is to include some indication of the cost of the test in the computer system. When the test is ordered, the ordering provider is aware of the exact cost of the test. Some institutions are using a dollar sign system to implement this. For example “$” may mean that a test costs under $50 and “$$$$$” may indicate a test costing over $5000, with other levels in between these two.
A third method is to have a lab “formulary.” Any test found in the formulary can be ordered with no problems. Tests that are not included in the formulary must be approved by the lab before being ordered and sent out.
Whatever method a laboratory uses, it is clear that some means of regulating the rising send out costs is going to be necessary for all labs. Until molecular diagnostic tests become automated and routine, they will continue to be expensive.
