The sustained impact of a group and screen and maximum surgical blood ordering schedule policy on the transfusion practice in gynaecology and obstetrics.
A retrospective study was carried out to examine the durability of the impact of Group and Screen (GS) and Maximum Surgical Blood Ordering Schedule (MSBOS) policy on transfusion practices. The study involved the Gynaecology and Obstetrics wards of the three Aberdeen teaching hospitals, all of which are supplied with blood and services by the transfusion laboratory of Aberdeen and North East of Scotland Blood Transfusion Service. The transfusion laboratory and hospital records were examined and analysed for all transfusion events in Gynaecology and Obstetrics during the three periods of 6 months immediately before, immediately after and 2 1/2-3 years following the introduction of a GS and MSBOS policy in November 1986. The number of units of blood crossmatched and units transfused decreased consistently and progressively to half the pre-GS and MSBOS level in both Gynaecology wards and Obstetrics wards during the study periods. This reduction was not associated with a decrease in the clinical workload. However, the crossmatched/transfused ratio (CTR) showed an immediate but transient improvement (3.6 to 2.2 to 3.4) and only partial and delayed improvement (10.1 to 9.6 to 7.7) with regard to blood use in the Gynaecology wards and the Obstetrics wards (respectively) during the three periods of 6 months indicated above. We conclude that the introduction of a GS and MSBOS policy can have a significant and sustained impact in reducing unnecessary blood ordering. The CTR may not be as sensitive an indicator of the effect of the introduction of GS and MSBOS as the total blood usage and a more detailed examination of blood use is necessary to assess performance and long-term impact.
