BOSTON – Even the most vigilant hospitals experience problems with blood storage and delivery on the patient floor, particularly in pediatric units, investigators cautioned.
A review of patient safety incidents that occurred surrounding more than 1 million transfusions in U.S. hospitals showed that pediatric transfusions were associated with a higher rate of safety problems compared with adult transfusions, with errors differing by age group.
“We just looked at units transfused [and] incidents that occurred during product administration and we found that the highest incident in the pediatric population is that the protocol is not being followed, and the highest incident in the adult population is that the transfusion is not performed, in error, at all,” said Sarah Vossoughi, MD, of Columbia University and New York–Presbyterian Hospital, New York.
In both settings, the investigators observed problems with product storage on the patient floor. “It’s very common for blood banks to find platelets in the refrigerator. It doesn’t matter how old you are or what type of hospital you’re at – everyone’s putting platelets in the fridge,” she said in an interview at AABB 2018, the annual meeting of the organization formerly known as the American Association of Blood Banks.
Dr. Vossoughi and her colleagues in New York and at the University of Vermont in Burlington noted that the National Patient Safety Foundation, now a part of the, declared preventable medical harm to be a public health crisis. In a paper published in the in 2016, researchers estimated that medical errors were the third leading cause of death in the United States, accounting for more than 250,000 fatalities annually.
Dr. Vossoughi also pointed to a study suggesting that the incidence of nonlethal medical errors may be 10- to 20-fold higher than the number of fatal errors ().
To evaluate patient safety events related to blood transfusions, Dr. Vossoughi and her colleagues drew data on events reported by three children’s hospitals and 29 adult hospitals to either the AABB Center for Patient Safety or the medical center’s own adverse event reporting system from January 2010 through September 2017.
They identified a total of 1,806 reports associated with approximately 1,088.884 transfusions. Of these reports, 249 were associated with 99,064 pediatric transfusions, and 1,577 were reported in association with 989,820 adult transfusions.
In all, 31% of the pediatric events were failure to follow the transfusion protocol.
“In a lot of the pediatric hospitals, it’s kind of like the Wild West. People say, ‘well I know it’s the hospital policy, but this child is special, so I’m going to do it this way, this time.’ That seems to be a culture in pediatrics, whereas on the adult side [clinicians] seem to be much less likely to just deviate from the protocol,” Dr. Vossoughi said.
Among adults, 43% of the errors were “transfusion not performed,” which may occur because of a bungled patient hand-off during a shift change, or when a patient is being moved from one unit to another.
“The next day, they’ll check the patient’s CBC and realize that the patient didn’t respond to the infusion that it turned out they never got, and then the product will be found on the floor, expired,” Dr. Vossoughi said.
In all, 20% of pediatric errors and 24% of adult errors were associated with incorrect storage of blood products on the patient floor.
The information they presented could help inpatient blood management programs target education and interventions to providers who commit similar errors.
“If you know that a particular provider group has problems following the protocol, maybe you can make the protocol a little simpler to follow, or make the checklist less cumbersome, and then maybe they’ll follow them more often,” she said.
The study was supported by the AABB Center for Patient Safety and University of Vermont Medical Center. The authors reported no conflicts of interest.
