| http://www.w3.org/ns/prov#value | - We talk about spending money on ???unnecessary testing???, but in most cases this is just unnecessary use of a fixed capital piece of equipment (ie a CT scanner), with very little additional real dollar cost; the scanner is already paid for and the tech is already at work, so while there is a bill generated for the CT, it doesn???t cost the hospital any more to do the study.
