FDA to Review Safety of Electroshock Devices Print E-mail
Monday, 24 January 2011

"Despite ongoing controversy, there has never been a large-scale, prospective study of the cognitive effects of electroconvulsive therapy (ECT)." Dr. Harold Sackeim, et al, 2007.

The classification of Electroshock  machines will be the focus of an FDA advisory committee hearing this Thursday and Frida, Jan. 26 & 27.

As noted by The New York Times (below) the hearing has reignited a contentious 50 year + debate about ECT's safety and efficacy.

In 1979, the FDA designated ECT devices as Class III, recognizing that its use posed serious risks--including permanent amnesia and brain damage. Despite the risks, FDA has allowed ECT devices to be used on patients--without requiring manufacturers to conduct safety tests, and without establishing any standards for the application of electric current to their brain. What's more, patients are not informed about the risks--so they have been unwitting human subjects of a vast uncontrolled experiment.

Once again, the powerful psychiatric lobby will join Electroshock device manufacturers in their effort to reclassify ECT machines from Class III, to Class II (benign risk)--in order to thwart a requirement for tests to determine whether ECT devices are safe for human application. 

The catalyst for this hearing is a Government Accountability Office recommendation in 2009 that high risk medical devices--such as electroshock machines, pacemaker electrodes, implanted blood access devices that had not undergone a stringent approval process-- should undergo proper safety tests, or--if deemed appropriate--should be reclassified as medium or low risk.     

The ECT literature is almost entirely corrupted by conflicts of interest--those who claim that ECT is "safe and effective" are the authors of self-serving, biased reports.

ECT proponents have indisputable financial stakes that collide with patients' best interest.
 
Device manufacturers have steadfastly refused all these years to put their machines to rigorous safety tests and ECT practitioners--who also have a financial stake in the ECT business, including close financial ties to ECT manufacturers. Practitioners have been applying varrying electric currents to the brains of patients without adhering to any standards of practice.
 
Indeed, the findings of the first large, prospective, federally funded study conducted by ECT’s most prominent researcher,  Dr. Harold Sackeim and colleagues at Columbia University, confirms its harm-producing results. Cognitive Effects of Electroconvulsive Therapy in Community Setting, Neuropsychopharmacology, 32:244-254 (2007):
This study provides the first evidence in a large, prospective sample that the adverse cognitive effects can persist for an extended period, and that they characterize routine treatment with ECT in community settings.
The study confirmed ECT-induced long-term memory loss and other cognitive problems--especially for women, who are the majority of persons who undergo ECT--and the study confirmed that electroshock methods, including electrode placement and electric voltage, varied widely among practitioners.
“It’s all trial and error — it’s all experimental," said Vera Hassner Sharav, president of the Alliance for Human Research Protection, an advocacy group in New York. "All the years it’s been controversial and there have not been clinical trials. Why not?”  

ECT practitioners operate in an unregulated, Devil-May-Care culture--psychiatry has the dubious distinction of disregarding the harm its "treatments" cause patients. 

Proponents of ECT proponents--i.e., device manufacturers, practitioners and organized psychiatry--dismissively deride patient testimonies, as if their first-hand experience isn't valid.  But in reallity, the most compelling testimony in opposition to ECT is the testimony of the eye witnesses--the patients whose memory and cognitive function has been damaged.

The Times also cites a very recent critical study, The Effectiveness of Electroconvulsive Therapy: Literature Review by John Read (New Zealand) and Richard Bentall (the UK) (both clinical psychologists with many years experience of working with severely distressed patients) published in the peer reviewed journal, Epidemiologia e Psichiatria SocialeThey reviewed "all relevant studies over 60 years" and found:
"only very minimal evidence for improvement during the treatment period and no evidence for improvement afterward....no evidence that ECT prevents suicide."
"strong evidence" for "persistent and, for some, permanent brain dysfunction." They concluded that "the cost-benefit analysis for ECT is so poor that its use cannot be scientifically justified."
They further stated, "The continued use of ECT therefore represents a failure to introduce the ideals of evidence-based medicine into psychiatry."
For the FDA to consider reclassifying ECT devices to Class II--the FDA would have to assert that ECT's safety can be assured by specified safeguards which would include the mandatory maintenance of records on the devices, labeling, performance standards or practice guidelines for use, and post-market surveillance such as patient registries.

F.D.A. Is Studying the Risk of Electroshock Devices

Federal regulators are weighing whether to downgrade the risk classification of electroshock devices, reinforcing what many psychiatrists consider a deepening acceptance of electroshock in modern therapy.

The procedure has had a resurgence in recent years. And an estimated 100,000 Americans — two-thirds of them women — undergo the treatment for major depression and other illnesses each year. Patients, anesthetized, receive a jolt of electricity from electrodes for several seconds, inducing a brain seizure and convulsions of up to a minute.

The American Psychiatric Association and other leading specialists are recommending that the Food and Drug Administration downgrade the devices to a medium-risk category from high risk, a move that will be reviewed by an agency advisory panel in Gaithersburg, Md., this week.

To some extent, the review has renewed the debate over electroshock. In 1990, F.D.A. staff proposed declaring the devices safe for major depression, but never took final action amid an uproar by opponents.

If the F.D.A. downgrades the devices to a medium-risk category, the equipment could be promoted and sold without new testing. Such a downgrade would place the devices in the same risk category as syringes and surgical drills.

If the F.D.A. leaves the devices in the high-risk category, however, manufacturers may, depending on the agency, have to withdraw them from the market.

The F.D.A. could require safety and effectiveness tests that have not previously been done. By regulating the devices, the F.D.A. is indirectly regulating the procedure.

The agency could make a formal decision later this year. The F.D.A. usually, but not always, follows recommendations of its advisory panels.

Supporters, including mainstream psychiatrists, say the treatment is much safer than it once was and could pass a rigorous F.D.A. review. But they assert that the device manufacturers cannot afford those tests.

“These tend to be mom-and-pop operations,” said Dr. Matthew V. Rudorfer, a psychiatrist and top specialist at the National Institute of Mental Health. “So I think the dilemma might be that undergoing new expensive clinical trials might be too expensive.”

Opponents, including some groups of former patients, maintain that electroshock can cause memory loss and brain damage that outweigh its short-term benefits.

“It’s all trial and error — it’s all experimental,” said Vera Hassner Sharav, president of the Alliance for Human Research Protection, an advocacy group in New York. “All the years it’s been controversial and there have not been clinical trials. Why not?”

Only two manufacturers, Somatics L.L.C. of Lake Bluff, Ill., and the Mecta Corporation of Lake Oswego, Ore., make the devices in the United States. The F.D.A. has asked them to submit all safety and effectiveness information as part of an agency review to be released before the advisory committee meeting beginning on Thursday.

Dr. Richard Abrams, who founded Somatics in 1983 with Dr. Conrad M. Swartz, and has written a textbook on electroshock, wrote the F.D.A. to say that none of his patients in more than 10,000 sessions over three decades had reported prolonged memory loss.

Dr. Swartz, who, like Dr. Abrams, is a retired psychiatry professor, said in an e-mail that any cognitive side effects from Somatics’ latest device “are distinctly less than they had been.” But he said Somatics could not afford an in-depth safety study that the F.D.A. could require if it left the devices in the high-risk category. That could cost millions of dollars.

“There is not nearly enough money in this industry to begin to pay for clinical trials that would be substantially larger than those already in the medical scientific literature,” Dr. Swartz wrote.

Mecta would not comment. “We always get negative press,” said a woman who answered the telephone at the company’s headquarters and did not give her name. “Too bad, because it’s good equipment.”

Somatics and Mecta each have annual revenue exceeding $1 million, according to Dun & Bradstreet. Dr. Swartz, asked about the revenue figure, said Somatics, like Mecta, was a private company. Their Web sites do not list prices or sales figures.

More than 1,000 hospitals and outpatient clinics in the United States use the two companies’ devices, according to Dr. Charles H. Kellner, a leading researcher, professor and chief of geriatric psychiatry at Mount Sinai School of Medicine in New York.

“It’s a treatment for the most severe form of depression,” Dr. Kellner said. “It can really be life-saving.”

The F.D.A. review was recommended by the Government Accountability Office in 2009 as part of an examination of the regulatory status of electroshock and about 20 other less controversial medical devices, like pacemaker electrodes and implanted blood access devices for hemodialysis. They were grandfathered into F.D.A. regulations when the agency was given more authority over medical devices in 1976.

The G.A.O. said those devices should go through the stringent approval process for high-risk devices or be reclassified as medium or low risk. A medium-risk designation could include adding controls like performance standards and patient registries.

The treatment costs $1,000 to $2,500 a session, and typically involves three sessions a week for two to four weeks, Dr. Kellner said. The fee includes the services of a psychiatrist and anesthesiologist. The equipment itself costs about $15,000 and may last years.

Patients are given short-term full anesthesia, a powerful muscle relaxant to prevent pain and subdue convulsions, and a mouth guard. The electrical current causes a grand mal seizure with convulsions usually lasting less than a minute, doctors say. Five to 10 minutes later, the patient awakens and can usually go home within two hours.

A federally financed study in 2007 found long-term memory loss and other cognitive problems, especially for female patients, from the treatment at seven New York facilities. The study, of 347 patients, was the first such large-scale study of side effects, despite what its authors called “over 50 years of clinical use and ongoing controversy.” The study also said methods and voltage varied widely among practitioners.

Dr. Rudorfer, associate director of treatment research in a division of the National Institute of Mental Health, says modern electroconvulsive therapy, or E.C.T., as its supporters prefer to call it, is much better than earlier practices, like those portrayed in “One Flew Over the Cuckoo’s Nest.”

“As surprising as it might seem, it never went away,” Dr. Rudorfer said of the treatment. “The field has had ample opportunity to get rid of E.C.T. and it’s still with us because it seems to occupy a small but important niche in treatment.”

But Dr. Rudorfer and other scientists still do not know just how the treatment or brain seizures act to improve moods. “We’re still looking,” he said. “It’s been very difficult to tease out the ‘active ingredient’ from among the many changes in the brain that accompany having, and stopping, the therapeutic seizure activity.”

Patients appear to have mixed views, judging from comments to the F.D.A. and electroshock-related Web sites. Some say it saved their lives, some say they suffered too much memory loss, and some say both.

In addition to its use in cases of severe depression, the treatment is used in some cases where speed is essential, like psychosis or suicidal behavior, for catatonia and in elderly patients who take so many other drugs that they cannot safely add a powerful psychiatric drug.

Dr. James H. Scully Jr., medical director and chief executive of the American Psychiatric Association, wrote the F.D.A. recently to say the treatment was “extremely effective and safe.” It provides relief some 80 percent of the time, he wrote. Dr. Scully and the psychiatry association also say there is no evidence it causes brain damage.

A task force is updating the association’s 2001 recommendations on the treatment. Its report is at least a year away.

“People use it because it works,” said Dr. Laura J. Fochtmann, a member of the task force, professor and director of the Electroconvulsive Therapy Service at Stony Brook University Medical Center, Long Island.

“These disorders can be extremely life-threatening, and when it works, it can be dramatically effective,” she said.

Opponents of electroshock include some patient advocacy groups, but the opponents, clearly, are outnumbered among physicians.

Dr. Peter R. Breggin, author of more than a dozen books including one about electroshock and a consultant in personal injury cases involving drugs and the therapy, says he is the only American psychiatrist he knows who opposes the treatment.

“It’s a big money-maker,” he said. “I would say if anything it’s been on the increase because there’s a market that’s been exploited, that is the elderly depressed women on Medicare. The reason for that is they’re covered, and there’s no one to protect them. What commonly stops shock treatment is a family member saying ‘over my dead body.’ ”

Depressed older people, Dr. Breggin said, can be helped more by a pet or conversation.

Last year, two psychology professors, John Read of the University of Auckland, New Zealand, and Richard Bentall of Bangor University, Wales, criticized electroshock after reviewing studies comparing it with simulated treatment. Their findings were published in Epidemiologia e Psichiatria Sociale, a peer-reviewed European psychiatric journal. “The cost-benefit analysis is so poor that its use cannot be scientifically justified,” Dr. Read wrote in an e-mail.

John Breeding, a psychologist and member of the Coalition for Abolition of Electroshock in Texas, said that state had banned electroshock for youths under 16 and required second opinions for treating the elderly, giving it the strictest rules in the nation.

“It’s a very strong treatment for despair and hopelessness,” he said. “It’s a temporary blunting of your feelings, so you feel better for a while, then you feel worse, and now you’ve got the memory loss and brain damage.”

The effectiveness of electroconvulsive therapy:  literature review

JOHN READ and RICHARD BENTALL
SUMMARY. Aim – To review the literature on the efficacy of electroconvulsive therapy [ECT], with a particular focus on
depression, its primary target group. Methods – PsycINFO, Medline, previous reviews and meta-analyses were searched in an
attempt to identify all studies comparing ECT with simulated-ECT [SECT]. Results – These placebo controlled studies show minimal
support for effectiveness with either depression or ‘schizophrenia’ during the course of treatment (i.e. only for some patients,
on some measures, sometimes perceived only by psychiatrists but not by other raters), and no evidence, for either diagnostic group,
of any benefits beyond the treatment period. There are no placebo-controlled studies evaluating the hypothesis that ECT prevents
suicide, and no robust evidence from other kinds of studies to support the hypothesis. Conclusions – Given the strong evidence
(summarised here) of persistent and, for some, permanent brain dysfunction, primarily evidenced in the form of retrograde and
anterograde amnesia, and the evidence of a slight but significant increased risk of death, the cost-benefit analysis for ECT is so
poor that its use cannot be scientifically justified.
