The utility rate medical equipment is an essential parameter for deciding the number of clinical units required for central control. But some articles in the past have defined optimum utility rates as 70%, give or take, obviously lower than actual figures from the clinical sites. Therefore, those figures failed to represent the reality of clinical fields well known for shortages of medical equipment. The discrepancies are caused by an underestimated influence of low utility rates of medical equipment in off-season.This time, the authors have discovered that it is possible to quantify the shortages of equipment correctly by calculating hourly utility rates. In addition, the authors have succeeded in establishing the hourly utility rate as a parameter for deciding the optimum number of units with an observation of the way the hourly utility rates may shift over the passage of time.The authors hope that a new kind of medical equipment control software will become available sometime in the future so that the utility rate is displayed on an hourly basis in the form of a graph.
