United Blood Services V. Quintana

In Quintana v. United Blood Services, 811 P.2d 424 (Colo. App. 1991), the court of appeals reversed a judgment entered on a jury verdict for the defendant, United Blood Services (UBS), in a negligence action brought by the plaintiffs, Mrs. Susie Quintana and her husband, Chris Quintana. The Quintanas claimed that UBS, a blood bank, was negligent in supplying a hospital with plasma contaminated with the Acquired Immune Deficiency Syndrome (AIDS) virus and that, as a result of UBS's negligence, the contaminated plasma was given to Mrs. Quintana during surgery and that she subsequently became infected with AIDS. The court of appeals held that the trial court erred in construing section 13-22-104, 6A C.R.S. (1987), as imposing a professional standard of care on a blood bank in acquiring, preparing, and transferring human blood or its components for transfusion into a human being and that the trial court, in its evidentiary rulings and jury instructions, also erred by applying the professional standard of care in a manner that rendered UBS's compliance with the professional standard the equivalent of conclusive proof of reasonable care. In place of the professional standard of care applied by the trial court, the court of appeals reasoned that UBS's conduct "should be measured against what a reasonable and prudent blood bank would or should have done under the same or similar circumstances" and that, under that standard of ordinary care, compliance with governmental regulations and industrial customs and practices would merely constitute evidence of reasonable care and would not be conclusive proof on that issue. 811 P.2d at 431. We granted certiorari to review  the decision of the court of appeals. We conclude, as did the court of appeals, that the Quintanas must be granted a new trial, but we do so for reasons different from those relied upon by the court of appeals.
