It seems everyone has a problem with incomplete transfusion slips. We have set our target at <2.0%. Last year our average was 5% incomplete. As of now we are 4.6%. It is a difficult task to manage. The nurses are required to take vitals 15 minutes prior transfusion, 15 minutes after transfusion started, and every half-hour until transfusion is completed. They document pre, 15 mins, and post on our Blood Bank transfusion slips.
