New rays on blood safety

March 2017—The language of blood banking experts, as they talk about irradiators, transfers easily to a car dealership. How reliable are the newer models? Are you willing to replace it every 10 years or so? Do you keep running it until it dies? What parts are likely to burn out? What will repairs run? And then the word “terrorism” pops up.

Blood bank: On guard against daratumumab interference

October 2016—As fans of spycraft know, offensive counterintelligence can include an arsenal of strategies: initiating a diversion, sowing confusion, creating false identities—anything that makes another party believe something that isn’t true. If the cancer treatment drug daratumumab were capable of deceptive intent, it might be accused of all those ploys when it comes to interfering with blood transfusion crossmatching. The reason: For patients receiving daratumumab, marketed as Darzalex by Janssen Pharmaceuticals, antibody testing for transfusion is subject to erratic false-positives, often leaving transfusion services confused, uncertain, and on hold.

26 ‘hot seat’ cases in new transfusion medicine text

February 2016—Transfusion Medicine in the Hot Seat: A Case-Based Primer is a new book from CAP Press, due to be released next month. The editor, Karen Quillen, MD, MPH, and her five contributors wrote 26 cases grouped into three sections: Antibodies, Blood Components, and Complications.

Mislabeling, wrong-blood-in-tube errors rare but there

November 2015—Blood is thicker than water, the saying goes. And thanks to a recent Q‑Probes, the rates of mislabeled specimens submitted for ABO blood typing and of wrong-blood-in-tube errors are now as clear as water. The mislabeling rate hasn’t changed much since a similar Q‑Probes study was performed in 2007. The 2015 Q‑Probes, “Blood Bank Safety Practices,” reviewed 41,333 specimens and found that 306, or 0.74 percent, were mislabeled. The previous study looked at 112,112 specimens, of which 1,258, or 1.12 percent, were mislabeled.

Next step in blood use program: end-of-life transfusion

October 2015—To improve blood usage in 2011, Advocate Health Care in Illinois launched a systemwide blood management program, “7 is the new 10.” Within two years of its implementation, there was a notable decrease in annual red cell usage from 64,178 to 41,000 red cell units, with overall savings of $10 million.

Groups urge phase-in of RHD genotyping

October 2015—It may not be quite like boxing frogs or herding cats. But gaining broad consensus on a laboratory medicine practice can be difficult, especially where multiple organizations must agree. A new joint statement on RHD genotyping by the CAP and the AABB, plus four other organizations, shows that such consensus is possible, however, even where it involves a laboratory medicine practice in place for more than 50 years—especially when advances in molecular testing are offering a solution to a problem.

Massive transfusion: a question of timing, detail, a golden ratio

December 2014—Here it was, the kind of massive postpartum hemorrhage case for which the team at Duke University Medical Center had spent months preparing. The multidisciplinary group had agreed on which laboratory tests would be done in such a case, determined which blood products would be delivered, and decided which members of the OB team would be sent racing to retrieve the potentially life-saving package.

AABB ramps up donor screening to help stem TRALI

October 2014—When it comes to the blood supply, the tradeoffs between safety and availability are a tightrope that blood centers walk with extreme care. For several years now, TRALI (transfusion-related acute lung injury) has topped the list of causes of transfusion-related mortality in the U.S. Defined as acute lung injury that occurs during or within six hours of transfusion of a blood product, TRALI is fatal to six to 10 percent of the patients it strikes.

For safety and savings, lab takes on transfusions

July 2014—Hospitals are under fire to cut costs, and more often than not that means layoffs, forgoing new equipment, and watching from the sidelines as the medical literature touts advances that could help patients now—if only institutions could afford to implement them.

Tuning in to hypotensive transfusion reactions

April 2014—Most pathologists are trained to think of hypotensive transfusion reactions as rare events, and for the most part they are. But one pathologist’s experience suggests these reactions may be underreported, and perhaps on the rise. Greater recognition of these events could provide valuable information and help improve patient outcomes. “People often report these reactions as possibly related to transfusions, but the challenge to the pathologist is that the transfusion reaction workups are negative, for the most part. So they’re in a quandary as to whether the drop in blood pressure was because of the transfusion or other causes,” says Richard M. Scanlan, MD, clinical professor, vice chair of laboratory medicine, and director of the transfusion medicine service at Oregon Health and Science University (OHSU).
