(2) Calculated by the number of times the instrument is used
S = (X1 + X2 + X3 + ...... + Xn)/Tn
The formula in the X1......Xn represents the number of times the instrument is used in a month (or a week). Tn represents time. (month or week) S represents the average number of instrument use.
Utilization rate = average number of times the equipment is used/approved number of times the instrument × 100%
(3) Estimation of the total effectiveness of the equipment
The total effectiveness of the equipment system of a hospital or department can be expressed by the following company
W = H/Q?S
W is the total effectiveness of the need to be sought, the total number of Q is the range of the instrument, H is the number of instruments in use, and S is the number of instruments in use. the number of instruments in use, S is the average utilization rate of the system instruments.
From the above formula, the greater the value of W, the greater the effectiveness of the equipment, the better the management. If the Q value increases, that is, by adding equipment alone, the W value is unlikely to increase, sometimes on the contrary, may shrink. So the use of this indicator, reflecting the utilization of real equipment utilization rate is high, indicating that the equipment management and utilization is good.
