Is routine preoperative crossmatching of blood necessary for elective surgery?
Routine preoperative crossmatching is unnecessary for the majority of elective surgeries, and a 'group and screen' policy is recommended to reduce excessive blood ordering.
Juma et al. (1990) conducted an observational in Elective surgery. Blood ordering routines was evaluated on Need for preoperative crossmatching of blood (transfusion index > 0.5). Current blood ordering routines for elective surgery resulted in excessive over-ordering for 77% of operations, with only 23% of procedures actually needing preoperative crossmatching.
