US blood banks experiencing biggest shortage in a decade

The pandemic has caused many supply-chain bottlenecks in everyday life, but few are as critical as the United States’ ever-shrinking blood banks. For the American Red Cross, which supplies about 40% of the nation’s blood, and other nonprofit blood centers, the problem lies mostly at the top of the chain: the diminishing number of healthy donors.

“This is the biggest challenge that I’ve seen in my 30 years in the business,” Chris Hrouda, president of biomedical services at the American Red Cross, said Thursday.

Donations of blood typically decline at this time of year, when holiday parties, wintry weather, seasonal illnesses, travel, and school and college breaks lead to lower donor turnout. But Hrouda said this month’s national supply had dipped to levels that the Red Cross has not seen in 10 years.

“We simply like to keep three days of inventory,” he said. “We’re struggling to keep one day.” Blood takes up to three days to be tested and prepared for patients.

Remote work, blood drive cancellations, and the limits that colleges and businesses have placed on the number of people allowed in public spaces have all reduced donor turnout.

Compounding the problem, the Red Cross, like many employers, is struggling to attract and retain employees amid the pandemic.

The critical shortage leaves hospitals to more carefully allocate the precious resource. “We have not had to delay any cases yet, but we are very mindful” of what our blood supply is, said Dr. Jennifer Andrews, medical director of the Vanderbilt University Medical Center blood bank in Nashville, Tennessee.

Vanderbilt, the only level-one trauma center in its region, has recalibrated the transfusions it uses to rescue patients — by using fewer red blood cells — to ensure that there is enough for all.

Other hospitals have altered treatment for some patients or canceled some patient surgeries, Red Cross officials said.
