This is what CMS says:-

Quote:
If a hospital is adjusting non-critical equipment maintenance frequencies to be below those recommended by the manufacturer, such adjustments must be based upon a systematic, evidence-based assessment. The hospital must document the assessment for all equipment with less frequent maintenance than what the manufacturer recommends, including the selected maintenance stategy that led to the lower adjusted frequency, and supporting evidence. The evidence must provide support that the frequency adjustment will not adversely affect patient or staff health and safety. The assessment of whether it is appropriate to use a maintenance strategy that results in less frequent maintenance than what the manufacturer recommends must be performed by qualified personnel. In the case of medical equipment, a clinical or biomedical technician or engineer should be considered qualified.

Straight away I can see that we need to agree on what is meant by "adversely affect"! think
