They determined that:
80.2% of blue tubes were wasted
49.5% of red tubes were wasted
9.8% of mint green tubes were wasted
86.9% of dark green tubes were wasted
12.4% of purple tubes were wasted
The total annual cost of the tubes and the cost to dispose these tubes as a biohazard was around $8.1K.If you weigh this cost against the pros of utilizing the rainbow the cost was actually pretty small. The average cost of LWOBS is estimated to be around $2,000 per patient. Jenney Mead
Regarding the collection of extra samples, the only problem I have with it is that the specimens are sometimes left at the bedside, and sometimes without any type of labeling, date/time of collection, etc. (I know...this NEVER happens at your institution) This is a problem on so many levels, e.g. sample mix-ups, improper storage, etc.Just my two cents...
This study analyzes extra blood tube usage over 6 years at the University of Iowa Hospitals and Clinics to examine how often extra tubes were used for add-on orders.
