The short answer, in my opinion, is yes.
The long answer is slightly more nuanced. As it turns out, studies suggest that one’s relative risk of death is increased in teaching hospitals by about 4-12% in July. That likely represents a small, but significant uptick in avoidable errors. It has been very difficult to quantify and document error rates related to inexperience. Intuitively we all know that professionals get better at what they do with time and practice… but how bad are doctors when they start out? Probably not equally so… and just as time is the best teacher, it is also the best weeder. Young doctors with book smarts but no clinical acumen may drop out of clinical medicine after a short course of doctoring. But before they do, they may take care of you or your loved ones.
It has been argued that young trainees “don’t practice in a vacuum” but are monitored by senior physicians, pharmacists, and nurses and therefore errors are unlikely. While I agree that this oversight is necessary and worthwhile, it is ultimately insufficient. Let me provide an illustrative example.
When I was a new intern I was assigned to a patient with curious eyelids. He was a mildly obese, middle aged man with a beard who spoke in hushed tones. What struck me the most was that he had voluminous upper eyelids. They were so strange that I couldn’t stop staring at them. He didn’t have any hives or red blotches on his skin, and his eyeballs were clear and white. There was no pus or discharge of any kind. I was so perplexed that I began to search through his medical record for answers before I embarrassed myself by asking for a consult. After many hours of digging, I discovered the smoking gun.
Apparently, he had been given repeat boluses of 1 Liter of IV normal saline by dutiful interns and residents who had not communicated with one another about who would write the order. So they all did. This man was so fluid overloaded that his eyes were literally bugging out of his head. No one had noticed the edema because of his size, and because (thank God) his heart and kidneys were young and healthy enough to handle the load without going into outright failure. Also, normal saline is such an innocuous medication that it didn’t flag any concerns by the nurses (who were also rotating through the service and busy swatting the more obvious mistakes being made by the fresh crop of interns).
If this poor patient had congestive heart failure or kidney disease, he could have been killed by well-meaning, diligent interns with salt water. Fortunately for him, he made a full recovery – and because there was technically “no harm done” I don’t even think this case was discussed in M&M (morbidity and mortality) conference, and I also doubt that anyone was reprimanded. Sounds crazy, but there are bigger fish to fry in July.
So my point is this: rookie mistakes are not always tracked, documented, addressed, or perhaps even noted. But they are real. They are scary. And they are lurking at every teaching hospital in this country. We must all remain on high alert – and question everything. Because even eyelids offer important clues, and water can kill.
If you or a loved one insist on falling ill in July, I recommend finding a hospital with a culture of carefulness or bring a patient advocate with you.

People's Choice Winning Idea: NephroZip
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 and had the courage to tackle the problem head-on. Three years ago, Avik Som organized “Problem Day” at his medical school (Washington University School of Medicine in St. Louis, MO) and invited his professors to an unrestricted “open mic” venting session.
Representatives from the departments of surgery, medicine, pediatrics and neurology attended. They described their frustrations and day-to-day struggles with the students for 3 hours straight. After decades of service to suffering patients, it was the first time that anyone had asked them to share their own stories.
And borne out of this collective catharsis was IDEA Labs (a 501c3 ) – a student-driven movement to tackle clinician problems with fresh ideas and the energy of youth. I attended the third annual “DemoDay” (also known as “Solution Day”) presentations in St. Louis this week and was amazed by the breadth and depth of the student solutions to specific clinical problems. From plastic ties to hasten renal surgical procedures to energy efficiency units for hospital HVAC systems – the ideas spanned many technical knowledge domains, and investors in the audience paid rapt attention.
This year’s first-place winning idea was the Cystoview adaptor. Bladder scopes (or cystoscopes) represent a surprising 0.5% of Medicare’s total annual expenditures. Yet they still rely on old analogue technology and their images are difficult to share and transfer. The Cystoview device converts any cystocscope from analogue to digital, and images can be uploaded anywhere – from a desktop computer to a smart phone. Once collected, digital images can be mapped and reconstructed into a 3-D bladder scan so that surgeons can plan to more effective tumor resections. In addition, having the cystoscopes go wireless reduces the risk of infection associated with cords dragging across surgical fields.
IDEA Labs is unusual for several reasons. First, it was designed as a joint venture between professional schools at Washington University – Avik Som wanted to draw talent from Engineering, Business, Law, and Sciences to create multi-disciplinary student teams. The cross-pollination of student ideas can lead to some especially creative solutions.
Second, students retain 100% of the intellectual property associated with their solutions. So whether they design a specialized lumbar puncture chair, digital cystoscopy device, wheelchair storage mechanism, or new blood test for cancer, they are responsible for pitching their idea to angel investors and creating a business plan that will bring their ideas to market.
Third, IDEA Labs is student-driven, and therefore agile and independent from the administrative and political hurdles that can slow down innovation at academic medical centers.
Last year IDEA Labs students raised $300K in venture capital funding for their ideas. This year, they raised $1.5M. They are also actively franchising their student innovation model to other schools across the country.
Ramin Lalezari is a second year medical student and Director of Recruitment for IDEA Labs’ Executive Board. He is also an American Resident Project fellow (an organization that seeks out promising young medical students and residents and supports their writing talent – they also sponsored DemoDay this year). I got the chance to catch up with him at DemoDay. He described how he got involved with the project as a first year student, and worked with a team of engineers to design a system that detected pre-syncope in hospitalized patients, reducing the risk of possible falls.
“When I heard that medicine lags 50 years behind technology, I was horrified. Why do we still have pagers and fax machines?” huffed Lalezari. “We must do better. Students themselves will drive technology and innovation. We are going to build a network of incubators across the U.S., using telemedicine when appropriate. If a student in Los Angeles is passionate about solving a urology problem with engineers in St. Louis, then we will facilitate it. The student project manager pitches his idea, and students nationwide can sign up to help. Some of these design ideas are going to change the face of medicine. That’s our end game.”
I asked Lalezari if IDEA Labs would draw students away from practicing clinical medicine.
“There is no doubt that these projects require a time commitment. A few teams have disbanded due to the overwhelming burden of studying for exams. So some are quitting IDEA Labs. On the other hand, I’ve heard of some students who become so invested in their ideas that they talk about making a career out of it.”
“Are other medical schools developing their own IDEA Labs model for entrepreneurship?” I asked.
“There are 24-hr ‘hackathon’ models out there, and senior design projects that are formalized courses. IDEA Labs projects are 9 months long, with mentor-guided progress reports every 2 months. Most schools foster entrepreneurship from the top down – administrators and professors drive the ideas and the schools retain the intellectual property. I think that the bottom up approach resonates much more strongly with students.”
IDEA Labs may have turned the long-entrenched apprenticeship model of healthcare innovation on its head. No longer are students vying for the honor of supporting the design ideas of senior physicians in unpaid or underpaid internships. They are identifying problems and solving them in teams of peers without the hierarchy imposed by academic-driven projects. They have leveled the playing field and stand to gain a lot more from their hard work than ever before.
Although medicine may still be a dinosaur when it comes to technology adoption and innovation, the IDEA Labs students are replacing the soloist T. Rexes with team-working Raptors. And that represents a true leap forward in the evolution of healthcare.
***Demo Day was sponsored by The American Resident Project and J&J Innovation. For more information about how to get your school involved with IDEA Labs, please contact firstname.lastname@example.org.

Wear and tear on the knee joints creates pain for up to 40% of Americans over age 45. There are plenty of over-the-counter (OTC) and prescription (Rx) osteoarthritis treatments available, but how effective are they relative to one another? A new meta-analysis published by the Annals of Internal Medicine may shed some light on this important question. After 3 months of the following treatments, here is how they compared to one another in terms of power to reduce pain, starting with strongest first:
#1. Knee injection with gel (Rx hyaluronic acid)
#2. Knee injection with steroid (Rx corticosteroid)
#3. Diclofenac (Voltaren – Rx oral NSAID)
#4. Ibuprofen (Motrin – OTC oral NSAID)
#5. Naproxen (Alleve – OTC oral NSAID)
#6. Celecoxib (Celebrex – Rx NSAID)
#7. Knee injection with saline solution (placebo injection)
#8. Acetaminophen (Tylenol – OTC Synthetic nonopiate derivative of p-aminophenol)
#9. Oral placebo (Sugar Pill)
I found this rank order list interesting for a few reasons. First of all, acetaminophen and celecoxib appear to be less effective than I had believed. Second, placebos may be demonstrably more effective the more invasive they are (injecting saline into the knee works better than acetaminophen, and significantly better than sugar pills). Third, injection of a cushion gel fluid is surprisingly effective, especially since its mechanism of action has little to do with direct reduction of inflammation (the cornerstone of most arthritis therapies). Perhaps mechanical treatments for pain have been underutilized? And finally, first line therapy with acetaminophen is not clinically superior to placebo.
There are several caveats to this information, of course. First of all, arthritis pain treatments must be customized to the individual and their unique tolerances and risk profiles. Mild pain need not be treated with medicines that carry higher risks (such as joint infection or gastrointestinal bleeding), and advanced arthritis sufferers may benefit from “jumping the line” and starting with stronger medicines. The study is limited in that treatments were only compared over a 3 month trial period, and we cannot be certain that the patient populations were substantially similar as the comparative effectiveness was calculated.
That being said, this study will influence my practice. I will likely lean towards recommending more effective therapies with my future patients, including careful consideration of injections and diclofenac for moderate to severe OA, and ibuprofen/naproxen for mild to moderate OA, while shying away from celecoxib and acetaminophen altogether. And as we already know, glucosamine and chondroitin have been convincingly shown to be no better than placebo, so save your money on those pills. The racket is expected to blossom into a $20 billion dollar industry by 2020 if we don’t curb our appetite for expensive placebos.
In conclusion, the elephant in the room is that weight loss and exercise are still the very best treatments for knee osteoarthritis. Check out the American Academy of Orthopedic Surgery’s recent list of evidence-based recommendations for the treatment of knee arthritis for more information about the full spectrum of treatment options.

A Cost Effective Fitness Band
In a new study published in the Annals of Internal Medicine, researchers found that overweight and obese patients who used a popular smart phone app (MyFitnessPal) did not lose significant weight after a 6 month trial period. The randomized controlled trial is the first of its kind to demonstrate that well-liked mobile apps may be ineffective for most users.
Two hundred and twelve racially diverse (73% female) patients treated at two UCLA primary care clinics were enrolled in the study. All indicated that they were interested in losing weight and 79% who completed the study indicated that they were “somewhat” or “completely” satisfied with the app, while 92% reported that they’d recommend it to a friend.
Unfortunately, as pleased as the subjects were with the app, there was no statistically significant difference in weight loss between the intervention and control groups. On average, the MyFitnessPal users lost 0.66 lbs in 6 months.
The authors note:
“Most participants rarely used the app after the first month of the study… Given these results it may not be worth a clinician’s time to prescribe MyFitnessPal to every overweight patient with a smart phone… Our analysis did not show any demographic covariates to be important predictors of app use.”
This study serves as a reminder that “popular” and “effective” do not always go hand-in-hand when it comes to weight loss interventions. While mHealth apps are expected to earn $26 billion by 2017, one is left to wonder if this money will be well spent or if we’ll all be “somewhat to completely satisfied” with the apps without anything medically significant to show for it?

I have spent many blog hours bemoaning the inadequate communication going on in hospitals today. Thanks to authors of a new study published in the New England Journal of Medicine, I have more objective data for my ranting. A prospective intervention study conducted at 9 academic children’s hospitals (and involving 10,740 patients over 18 months) revealed that requiring resident physicians to adopt a formal “hand off” process at shift change resulted in a 30% reduction of medical errors.
What was the intervention exactly? Details are available via mail order from the folks at Boston Children’s Hospital. It may take me a few weeks to get my hands on the curriculum (which was supported by a grant from the Department of Health and Human Services). I’m not sure how complex the new handoff initiative is in practice (or if it’s something that could be replicated without government-approved formality) but one thing is certain: disciplined physician communication saves lives.
I myself (without a grant from HHS or a NEJM study to back my assertions – ahem) proposed a set of comprehensive communication practices that can help to reduce medical errors in the hospital. My list involves more than peer hand-offs, but also nursing communication, EMR documentation strategies, and reliance on pharmacists for medication reconciliation and review. It is more than just an information exchange protocol for shift-changes, it is a lifestyle choice.
I applaud the I-PASS Handoff Study for its rigorous, evidence-based approach to implementing communication interventions among pediatric residents in children’s hospitals. I am stunned by how effective this one intervention has been – but a part of me is saddened that we practically had to mandate the obvious before it got done. What will it take for physicians to adopt safer communications strategies for inpatient care? I’m guessing that for many of us, it will involve enrollment in a workshop with hospital administration-driven requirements for participation.
For others of us – regular communication with staff, patients, and peers already defines our medical practice. But because (apparently?) we are not in the majority, we’ll just carry on our instinctual carefulness and wait for the rest to catch up. At least now we know that there is a path forward regarding improving communication skills and transfer of patient information. If we have to force doctors to look up from their iPhones and sit around a table and speak to one another – then so be it. The process may improve our lives while it saves those of our patients.
