FDA Tightens Safety Rules for Radiation Therapy Machines

The Food and Drug Administration has canceled its policy of giving rubber-stamp approval to marketing of powerful new radiation therapy equipment like linear accelerators. From now on, the manufacturer of the machine is going to have to prove the equipment has proper safety checks to prevent dangerous overdoses of radiation to patients.

The New York Times ran a series in January 2010 that exposed some horrific tragedies that occurred, particularly when hospitals rushed into operation new and complicated equipment without thorough safety checks and training of technicians. The series also showed that the equipment often lacked simple fail-safe devices such as a way of preventing the machine from delivering a walloping overdose of radiation even if one had been inadvertently programmed by a technician.

But since the FDA only has power over manufacturers and not over hospitals themselves, it still will be possible for poorly trained technicians to cause errors that hurt patients by either delivering overdoses or underdoses of radiation.

In a follow-up article, the New York Times' Walt Bogdanich quotes Dr. Howard I. Amols, chief of clinical physics at Memorial Sloan-Kettering Cancer Center in New York, as saying the more serious problems stem from shortcomings in staffing, personnel competency and hospital quality assurance programs:

“I’d also caution that however commendable tougher standards for premarket approval of software may be, its not clear that F.D.A. has the expertise to police this,” Dr. Amols said. “In fact, I’m not sure anybody does. That’s one of the big problems with software. It comes down to a qualified user recognizing that something is amiss.”

While the government regulators are getting their act together, my advice for patients is to always make sure you get radiation therapy at only a leading center that has been doing it for a long time. Make sure the center employs licensed, certified technicians to operate the therapy machines. Don't be dazzled by the new smell and clean look of a spanking-new therapy center. That could be a sign that people aren't well trained yet to keep you safe.

FDA Has New Initiative on Excessive Radiation to Patients

The scandal about injuries to cancer patients from malpractice in radiation therapy has had one beneficial side effect: the Food and Drug Administration is gaining urgency and attention for its new initiative to reduce unnecessary radiation in diagnostic imaging of patients.

Here is a link to the FDA's White Paper on its steps to make sure patients get only the dosage of radiation needed, at the right time and in the right way.

One part of the project is to make it easy for patients to keep track of how much radiation they've had, because accumulated dosing is what causes long-term injuries. The FDA says it is working

to develop and disseminate a patient medical imaging record card.26 FDA will make this card available on our website. While ultimately the best way of tracking a patient’s history of radiation exposure will be to incorporate it into that patient’s paper or electronic medical record, a personal record card will give patients and their caregivers a means, in the short term, of tracking their own medical imaging histories and sharing this information with their physicians. This will help facilitate critical discussions between patients and providers about the best available clinical options.

Better Care with the Tried and True, or the Seduction of the New?

Time and again in U.S. health care, new technologies are hurried into wide use with little testing, scant training of their human operators, and lack of solid evidence that newer really is better. After the flush of optimism has faded, billions of dollars later, we learn how to judiciously use the new equipment, but only after patients have been hurt or killed by the rush to the new.

The latest example is the deployment of new radiation therapy machines on cancer patients with operators who are not properly trained or credentialed and equipment that has not been tested or calibrated. The New York Times' recent investigative series on the subject prompted one knowledgeable reader, Dr. Joseph Imperato, medical director of the Center for Advanced Radiation Medicine at Lake Forest (Ill.) Hospital. to write this:

To the Editor:

As a radiation oncologist practicing for 25 years, I believe that there is a crucial part of the story of radiation mishaps that has not been mentioned: the “nuclear arms race,” in which people want the newest technologies, without stopping to think about who is operating them.

In the past, academic medical centers were typically the first to obtain and use new technologies. The equipment would be thoroughly vetted and reported on in peer review articles before being accepted and used by the smaller community hospitals.

Now the reverse is true. Small community hospitals often far outpace academic medical centers. One example is the proliferation of proton centers run by for-profit companies. Often the staff has limited knowledge and experience with this extraordinarily complex equipment. And new technologies are often assumed by the public to be better, even though there is often little firm clinical data to support that.

As we struggle as a country to come to grips with health care costs, this is one area where there is great opportunity for savings. Clinical reviews can prevent the proliferation of needlessly expensive technology. What the public must come to grips with is that “new” is not automatically “better.”

See the Times' letters section for more.

In my book, "The Life You Save," I have several chapters that speak to this issue, particularly with new drugs. What patients need to understand is that whatever the technology, the early years of use are in essence a continuation of the testing phase. If you are comfortable with being a guinea pig, that's fine, but very often you can get better, safer care with the tried and true. And if the new technology looks enticing, go with an operator who has the most experience using it, because practice does make perfect.

Preventing Malpractice in Radiation Therapy

What can cancer patients do to protect themselves from malpractice in radiation therapy? This urgent question arises from a lengthy series of investigative reports in the New York Times. The articles exposed serious patient injuries that stem from therapists who are overwhelmed and inexperienced, lax regulation and indifference by hospital administrators.

A key part of the problem is that technological sophistication has outrun the ability of the humans running the radiation machines to monitor the safety of the radiation beams they train on patients' bodies.

Another issue is that no central agency is responsible for inspecting the machines and credentialing the people who run them. Depending on the type of radiation involved, the Food and Drug Administration, the Nuclear Regulatory Commission and various state health agencies could have jurisdiction. Or worse, each could claim that someone else has the jurisdiction, and the patient can slip through the cracks.

There is one simple way that patients can take some measure of self-protection. That is to make sure that the radiation therapy center treating you has significant experience, in years not months, with the specific machine being used on you. Too often, hospital administrators buy a fancy new machine, advertise it heavily in glossy brochures, but don't take the time to make sure the machine is properly calibrated and that the medical physicists who operate the machine are fully trained.

You should also ask if the machine treating you has been inspected recently by an independent agency. One federally funded inspection and testing service is the Radiological Physics Center, operated out of MD Anderson Hospital in Houston. It does inspections for any radiation center that wants to receive federal funding for clinical trials. The Center found in 2008 that nearly three in ten hospitals it inspected failed to accurately irradiate a test dummy using IMRT technology.

The Times also found rampant problems with fake credentials among medical physicists, who are in charge of making sure patients get the right dose of radiation. The American Board of Radiology certifies medical physicists in one of three sub-specialties. You can check if a physicist is certified at the umbrella website for all medical board certifications, the American Board of Medical Specialties. Click here to go to the login page to search for a medical physicist's certification. The same page will let you search for whether a doctor is board-certified in any of the ABMS specialties or sub-specialties.

Also, the American Board of Medical Physics runs some certification programs. Its website has lists of diplomates but lacks any searchable database of qualified physicists. So the ABMS website is a better choice.

I recommend that patients ask questions to find out the qualifications of the persons running your radiation treatment program. If they lack certification, why take a chance?

I discuss the certification issue in detail in my book, "The Life You Save: Nine Steps to Finding the Best Medical Care -- and Avoiding the Worst." Many of the most egregious cases of malpractice that I have prosecuted for victims' families have involved doctors who lacked basic board certifications.

Malpractice in Radiation Therapy: Hideous Injuries from Lack of Simple Checklists

More evidence of the urgent need for "checklists" to protect patient safety in complex medical treatments comes with a long article in the New York Times about terrible injuries from malpractice episodes during radiation therapy. Yet readers have to dive deep into the article to find this key point.

Scott Jerome-Parks suffered terrible radiation burns to his neck, and lingered for two years in agony before dying, because he received a seven-fold overdose in the radiation that was supposed to treat his tongue cancer, on three separate occasions. Why did it happen? The hospital, St. Vincent's in New York, blamed a confluence of tragic coincidences. But I reached a different conclusion, as I wrote in a blog post to the Times' "Well" blog:

Deep in this tragic article is the following paragraph that exposes the reforms that are needed before medical care can become safe for all patients:

"It was customary — though not mandatory — that the physicist would run a test before the first treatment to make sure that the computer had been programmed correctly. Yet that was not done until after the third overdose."

So there you have it. If the physicist had been required to run the test -- better yet, if the equipment had been set so that it wouldn't work until the final test had been run -- Scott Jerome-Parks would not have suffered the hideous injuries so eloquently described in the article.

Medicine needs to adopt standard and mandatory - not merely "customary" -- checklist routines to ensure the safety of patients. This is the thesis of Atul Gawande's new book, "The Checklist Manifesto," and I have a chapter on how patients can enforce checklist protocols before surgery in my own book, "The Life You Save: Nine Steps to Finding the Best Medical Care -- and Avoiding the Worst."

Many medical commenters on the New York Times "Well" blog defensively say, "We're only human," to excuse these kinds of errors. Yes! That's exactly the point of the checklist. It recognizes that we're all only human and that when we are deploying potentially deadly treatments, a final check and double-check is needed, every time, before pressing the button.

The Times also found that the manufacturer of the software that ran the linear accelerator, which delivered the radiation, did not have in place until after the injury a simple "fail-safe" mechanism to prevent the kind of error that occurred.

The entire article by the brilliant reporter, Walt Bogdanich, is worth reading. Here is the Times' own summary of the article:

The Times found that while this new technology allows doctors to more accurately attack tumors and reduce certain mistakes, its complexity has created new avenues for error — through software flaws, faulty programming, poor safety procedures or inadequate staffing and training. When those errors occur, they can be crippling.

I also recommend that readers interested in patient safety issues go through some of the NYT "Well" blog posts on this article.
