It has been difficult over the years to apply common planning models for staffing, that is, case mix, patient acuity, relative value unit, and patient days. For clinical engineering, it does not matter whether the facility is running at capacity or if units are slow and surgeries are down. Certainly, a low census makes it easier to perform preventive maintenance inspections. It became very important to begin to utilize the data that we have painstakingly tracked, at least via computer, for the last 2 decades. What we have come to realize is that in our early days, late 1970's early 1980's, the clinical engineering staff was managing 300 pieces of equipment and flashing forward to today where 1500 to 1700 pieces are the mark of efficiency. Equipment is more reliable; built-in, self-test routines are abundant, and exception testing is the standard practice. Our work is solely based on equipment count, scheduled preventive maintenance load, and expected service. More specifically, our data reflects the true hands-on staff accountability.
