ARE RETROSPECTIVE PEER-REVIEW TRANSFUSION MONITORING SYSTEMS EFFECTIVE IN REDUCING RED-BLOOD-CELL UTILIZATION

Objective.-This research used a study-control group design and examine d data collected from five hospitals to evaluate the effectiveness of retrospective peer-review systems on reducing utilization of red blood cells (RBCs). Design.-The effects of retrospective peer-review system s were studied in three parts: (1) trends of RBC utilization were comp ared by the slopes of linear regression lines that assessed the effect of time on RBC utilization among four study hospitals and one control hospital, (2) diagnosis-specific RBC utilization was compared between the control hospital and one matched study hospital, and (3) the effe ct of the retrospective review system of one study hospital was assess ed by linear regression using data accumulated 1 year before and 2 yea rs after implementation of the program. Results.-Three study hospitals showed no significant changes in RBC utilization during the 10-month study period. One study hospital and the control hospital demonstrated trends of reduced RBC use with negative slopes of regression lines; h owever, there was no difference in the degree of the two slopes, and t he diagnosis-specific RBC utilization was not lower at the study hospi tal than at the control hospital. Furthermore, implementation of the r etrospective peer-review system at one study hospital demonstrated no effect on RBC utilization.Conclusions.-We conclude that the retrospect ive peer-review systems implemented at these four hospitals had no eff ect on reducing red blood cell utilization.
