A paper published in the February issue of Health Affairs — discussed at length in an article in the New York Times — contains the sort of blunt, plain-spoken language you seldom read in academic journals. The authors, who include some of the most prominent neuroscientists and ethicists in the world, warn that manufacturers are misusing the FDA’s humanitarian device exemption to promote deep brain stimulation as a “treatment” for obsessive compulsive disorder (OCD).
In fact, they make clear that deep brain stimulation is very much an experimental procedure. Research is still at an early stage, and the risks to patients are not well defined. When suffering is severe and no other treatment has provided relief, there is value in making available an intervention like deep brain stimulation. But misleading or biased information, no matter where it comes from, certainly undermines patients’ ability to calculate benefits and risks.
To enable deep brain stimulation, a surgeon must first implant electrodes in the brain and connect them to a pair of small electrical generators underneath the collarbone. Deep brain stimulation uses electricity to affect how brain signals are transmitted in particular areas of the brain. The image to the left, from the National Institute of Mental Health, shows how deep brain stimulation depends on the implantation of pulse generators below the collarbone and electrodes in the brain.
Specific concerns are raised by the article in Health Affairs (and in our own article on this topic last year in the Harvard Mental Health Letter). Read more »
The recurring narrative among health reformers is that hospitals that provide more care raise health costs, but don’t necessarily improve quality. This has lead to a backlash against so-called “aggressive” hospitals and doctors, with upcoming financial penalties to match. But the situation, as always, appears to be more nuanced than that.
In her column in the New York Times, Dr. Pauline Chen looks at one subset of patients who actually may benefit from aggressive care: Those who suffer surgical complications. The study,
found no difference in the rate of complications for aggressive and nonaggressive hospitals. But when they looked at all the patients who had complications and examined their outcomes, the researchers found that regardless of the urgency of their operations, those patients who were cared for at more aggressive hospitals were significantly more likely to survive their complications than those who had their operations at less aggressive hospitals.
In addition, the investigators found that characteristics associated with intensity of care treated surgical complications better:
… a hospital’s failure or success in treating surgical complications correlated consistently with factors that also characterized intensity of care — general expenditures, intensive care unit use and the total days of hospitalization — they found that benefits of this more aggressive care extended well beyond the time of the operation.
I constantly remind readers of this blog that more medicine isn’t necessarily better. The counter-intuitive findings from the Dartmouth Atlas study have been instructive in convincing patients that they are, in many cases, overtreated. Read more »

If you’ve been watching Jeopardy! over the past couple days, you probably know that IBM’s highly-advanced artificial intelligence software, Watson, has been competing against Jeopardy!’s most successful contestants (and as of Tuesday night, took a commanding lead over the humans, despite having some trouble with United States geography).
Besides the amazing ability to power through “Daily Doubles” and answer random trivia in the form of a question, IBM researchers believe that Watson could revolutionize the healthcare industry. From diagnostics to informatics, Watson could quickly search through medical records, clinical documents, and research information for precise answers that would benefit both doctors and patients.
Check out the video below to see physicians explain how Watson’s technology could transform medicine.
Also watch the TED.com webcast of Dr. David Ferrucci (Principal Investigator of the DeepQA/Watson project at IBM), Dr. Herbert Chase (Professor of Clinical Medicine at Columbia University School of Physicians and Surgeons), and others discussing the Jeopardy! challenge and the impact the technology behind Watson could have on society.
Bioadhesives are a reasonable alternative to sutures for repair of perineal lacerations sustained during childbirth, according to a poster presentation at last week’s annual meeting of the Society for Maternal-Fetal Medicine.
Researchers at the Hadassah Hebrew University Medical Center in Jerusalem randomized women with first degree perineal tears to either 2-octyl cyanoacrylate (Dermabond) adhesive glue or suture for wound closure. While healing and incisional pain was similar, women who received the adhesive closure were more satisfied than those who were sutured.
In Portugal, bioadhesives have been studied for closure of the top skin layer of an episiotomy repair, and found to shorten the duration of the procedure with similar outcomes to suture in terms of pain, healing, and infection.
Biologic adhesives are chemically related to Super Glue, which is ethyl-cyanoacrylate. Midwives have been using Super Glue for perineal wound repair for some time, according to Anne Frye, who has authored a book on wound closure for midwives, and who gives instructions for its use in repair of perineal lacerations. Apparently Super Glue was also used by the military during Vietnam for wound closure.
A PubMed search on Dermabond finds multiple studies of its use, from plastic surgery to mastectomy, surgical wound closure, retinal surgery, lung and gastric leak closure, and even on esophageal varices. RL Bates mentions Dermabond as an option to repair skin tears in elderly patients. This stuff is turning into the duct tape of the medical profession.
It’s important to remember that adhesives are only for superficial skin closure, as use in deeper layers can cause irritation and burning of tissues. Side effects of their use include irritation and allergic reactions and of course wound infections, and pain can always occur no matter how one closes a wound.
Less than one in three primary care practices offer all 10 recommended adult vaccines, citing a variety of financial and logistical reasons.
Researchers sponsored by the Centers for Disease Control and Prevention sampled 993 family physicians and 997 general internists. Of the respondents, 27 percent (31 percent of family practitioners and 20 percent of internists) stocked all 10. Results appear in the Feb. 17 issue of the journal Vaccine.
The 10 vaccines were hepatitis A; hepatitis B; human papillomavirus vaccine (HPV); combined measles, mumps, and rubella (MMR); meningococcal conjugate vaccine (MCV4); pneumococcal polysaccharide (PPSV23); tetanus diphtheria (Td); combined tetanus, diphtheria, and pertussis (Tdap); varicella; and zoster.
Of the responding practices, two percent plan to stop vaccine purchases, 12 percent plan to increase them and the rest had no plans to change their vaccination stocking habits. But physicians who identified themselves as their respective practices’ decision makers for stocking vaccines were more likely to decrease the number of different vaccines stocked for adults (11 percent vs. three percent; P=.0001).
The National Vaccine Advisory Committee, a group that advises the various federal agencies involved in vaccines and immunizations, arrived at even bleaker figures in 2009, reported the April 2009 issue of ACP Internist. For example, 62 percent of decision makers in practices said they had delayed purchase of a vaccine at some time in the prior three years due to financial concerns. And in the prior year, 16 percent of practice decision makers had seriously considered stopping vaccinations for privately-insured patients due to the cost and reimbursement issues. Read more »

It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
