Looking again at what CMS is saying, they make it very clear that even where revised scheduling (of PM) is permitted, it the interval - not the procedure itself - which may be adjusted.

That is (and I quote):- "alternative equipment maintenance methods are not permitted".

And that:- "hospitals must continue to follow the manufacturer's recommended techniques for maintaining equipment, even if the hospitals alter the frequency of maintenance activities".

But OK ... PM intervals for "non-critical" [definition required] equipment may be varied (lengthened, presumably), just as long as such a change is supported (justified) by "evidence".

What form does this "evidence" take I wonder? think

That is:- how do we satisfy the Managers, the Bean Counters, Lawyers and Miscellaneous Suits ... et al (and anyone else who routinely stands in the way of progress in general)?

Meanwhile, here is some more on EBM (Evidence-Based Maintenance) (.pdf). smile
