No one should die from a blood transfusion. So why did it happen at MD Anderson, the nation’s top cancer hospital?

 

By Mike Hixenbaugh, NBC News.

In early December, a nurse at the University of Texas MD Anderson Cancer Center gave a 23-year-old leukemia patient a blood transfusion that, unbeknownst to the medical staff, had become contaminated with bacteria.

The patient’s blood pressure soon plummeted, but there’s no evidence anyone at the nation’s top-ranked cancer hospital was actively monitoring her vital signs in the crucial moments during and after the procedure, a federal investigation found. She died a little more than a day later.

The potentially preventable death drew a harsh rebuke from the Centers for Medicare and Medicaid Services, whose subsequent investigation, made public Monday, uncovered systemic safety lapses at the hospital. Nurses were not properly monitoring patients’ vital signs while administering blood transfusions, not only in the case of the patient who died, but also in 18 out of 33 other cases examined, the investigation found.

Since receiving the federal report this month, the hospital’s leaders have made changes to improve training for nurses and require hourly checks on patients during transfusions.

“We are unwavering in our commitment to our patients, not only in their battle against cancer, but to provide the safest, highest quality environment to receive their care,” Rosanna Morris, the hospital’s chief operating officer, said in an interview Tuesday. “This event only helps to make us even better.”

But the death raised a question that has confounded patient safety advocates: Given all the advancements in technology and safety protocols over the past three decades, how can such errors still happen at even the most prestigious hospitals?

Fatal blood transfusions are so rare and so preventable that they are counted among a class of medical mistakes that experts say should never happen. Included on the list of so-called never events: Leaving medical equipment inside a patient after surgery. Operating on the wrong patient or on the wrong body part. Giving patients contaminated drugs.

Such egregious errors can seem shocking to the general public, said Dr. Peter Pronovost, a leading hospital safety expert and the chief clinical transformation officer at University Hospitals in Cleveland.

Blood transfusions are considered a poster child for how hospitals can improve outcomes and prevent errors, Pronovost said. Every day across the country, tens of thousands of people receive donated platelets, plasma or red blood cells to combat disease or replace blood lost during surgery. In the vast majority of cases, the procedure is lifesaving.

“It’s risky,” Pronovost said, “yet also incredibly safe.”

Of 17 million blood transfusions in 2017, 37 patients died as a direct result, according to the Food and Drug Administration. Most died of allergic reactions or other complications, but in five cases the patients received platelets contaminated with bacteria, and in seven cases patients were given the wrong blood type.

Transfusion deaths have become rarer over the past two decades with the advent of bar-coding technology, which ensures patients always receive the right type of blood, and with the implementation of strict protocols to catch adverse reactions before patients become gravely ill.

But those safeguards only work if hospitals make them a priority, said Erica Mobley, director of operations at the Leapfrog Group, which grades hospitals based on safety. She said too many hospitals still fail to do so, prioritizing volume over quality and leaving patients vulnerable.

“In many cases, when these horrible mistakes occur in hospitals, it’s a system error,” Mobley said. “Humans are inevitably going to make errors, but there should be systems in place to prevent those mistakes from leading to harm.”

Experts say it’s important to track a patient’s temperature, blood pressure and pulse during a transfusion, which allows the medical staff to identify adverse reactions early and, in most cases, stop the procedure before a patient is seriously harmed. That failed to happen in the MD Anderson case.

News of the death shocked some hospital safety experts, given MD Anderson’s reputation as one of the nation’s best cancer centers. The hospital draws patients from across the world every year to its gleaming facilities in Houston. The death came two months after one of the hospital’s top researchers was awarded the Nobel Prize in Medicine for his work in developing a revolutionary treatment that harnesses the immune system to attack cancer cells.

“These deficiencies have been determined to be of such a serious nature as to substantially limit your hospital’s capacity to render adequate care,” the Centers for Medicare and Medicaid Services wrote in a June 3 letter to Dr. Peter Pisters, MD Anderson’s president.

In interviews with regulators, many of MD Anderson’s nurses did not seem to realize they were supposed to regularly monitor patients while giving them blood, explaining that they checked the patients once shortly after the transfusion began and once afterward. That left vital signs of several patients unchecked for hours at a time.

One nurse explained that patients were trained to detect signs of adverse reactions, and that it was their responsibility to notify nurses if something seemed to be going wrong: “We educate the patients about the transfusion,” the unidentified nurse said, according to the report. “Patients know to call.”

MD Anderson staff also had routinely failed to inform patients about potential risks associated with transfusions, in several cases relying on informed consent documents that patients had signed months or even years earlier, according to the report.

The hospital submitted a plan of correction this month that pledged changes to training and patient checks. In addition, the hospital announced it was launching a first-of-its kind command center to continuously track the vital signs of every patient receiving a transfusion at the hospital.

“As a learning organization, we’re truly welcoming and embracing this as an opportunity to not only better some of our existing policies and procedures, but also to enhance our work and create new best practices,” Morris, the hospital’s chief operating officer, said.

A separate government inspection found deficiencies at the MD Anderson lab that processes blood used in transfusions, according to another letter sent to the hospital this month. That report has not yet been made public, and it’s not clear whether hospital technicians could or should have detected the bacteria-infected blood that led to the woman’s death.

The Food and Drug Administration requires labs to screen blood platelets for bacteria contamination prior to transfusions, but experts say the methods are not foolproof.

“Technology works a lot of the time, 76 to 80 percent of the time can detect if a blood product is contaminated, but there are no systems that we are aware of today that work 100 percent of the time,” Morris said.

Other problems are more easily prevented. The same week that the patient died at MD Anderson, a 75-year-old woman was given a transfusion with the wrong type of blood at Baylor St. Luke’s Medical Center, a hospital across the street that’s long been regarded as one of the nation’s best for heart surgery.

In that case, medical staff had drawn blood from an emergency room patient but failed to discard the sample after that patient was sent home. The vial was left in the hospital room when staff brought in the 75-year-old, who had been rushed to St. Luke’s by ambulance. When a doctor ordered a transfusion for her, staff mistakenly sent the tube containing the prior patient’s blood sample, placing a new label over the original.

The patient died the next day after going into cardiac arrest.

The mistake that killed her followed a pattern of blood labeling errors at the Houston hospital, according to an inspection report released in February.

“These are really basic errors that I didn’t really think happened that often anymore,” Dr. Ashish Jha, who directs Harvard University’s Global Health Institute, said at the time.

In the wake of the mistake, the hospital’s board of directors fired three top executives and promised to implement sweeping reforms, which are now ongoing.

“It is our responsibility to learn from these mistakes, and we take this responsibility very seriously,” the hospital’s president, Doug Lawson, wrote in an open letter two months after the death. “An incident like this should never happen.”

CORRECTION (June 26, 2019, 12:36 p.m. ET): An earlier version of this article misstated the month that MD Anderson received a federal report on problems with blood transfusions at the hospital. MD Anderson received the report and sent a response in June, not in May.
