The second column of the Table 7 shows the overall performance of the
medical diagnostic laboratory units. We have identified efficient units
in gray. The results show that three units are efficient and 22 units
are inefficient. Also, the average efficiency of the reception unit, the
sampling unit, the test unit and the results test unit are 0.80, 0.93,
0.97 and 0.90, respectively. The average efficiency scores show that the
decrease of the reception unit’s efficiency results in a decrease of the
efficiency of each laboratory. Therefore, by decreasing the number of
admitted patients as the intermediate values of the reception unit and
the sampling unit, the efficiency of the reception unit decreases. In
order to prevent the performance decrease of laboratories, laboratories
should increase patients to the use of their laboratory services through
appropriate management strategies. The performance ranking of 25 Labs is
rated in Table 8 as follows:
