We cannot justify the considerable additional cost of making such single-use syringes generally available on prescription to all insulin-dependent diabetics.
In part, this is due to the current lower price of single-use hemodialyzers, but it also reflects our inclusion of additional costs (heparinized saline, rental and construction costs).
Since hemodialyzers are generally used only once and discarded after each treatment (single-use dialysis), 10% of an outpatient hemodialysis program's budget is often spent on hemodialyzers.
We do provide estimates, however, of the cost-savings that could be achieved for single-use programs that are currently using highflux dialyzers.
In fact, no previous prospective clinical trials or economic evaluations have examined the health and resource implications of hemodialyzer reuse when compared with single-use dialysis.
We might describe such a pair of functions as a pair of 'single-use isomorphisms'.
For this reason single-use configuration systems, which do not clearly separate configuration knowledge from the configuration program are doomed to failure.
The evaluations showed that while technologies need to be adapted, a single-use technology had little chance of large-scale adoption.
