iPhone App Offers Sufficient CT Image Resolution To Diagnose Strokes Remotely

cuqf1gz9.jpg Researchers from the University of Calgary have shown that doctors can make a stroke diagnosis using an iPhone application just as accurately (and faster) than they can on a traditional computer. In a study recently published by Journal of Medical Internet Research, two neuro-radiologists looked at 120 consecutive noncontrast computed tomography (NCCT) scans and 70 computed tomography angiogram (CTA) head scans. One used a diagnostic workstation and the other using Calgary Scientific‘s ResolutionMD Mobile app. The study results showed that using the ResolutionMD app is between 94%-100% accurate in diagnosing acute stroke, compared to a medical workstation.

In addition to accurately diagnosing a stroke, the app was also praised for its ability to handle a large number of images seamlessly and to detect subtle, but potentially critical findings in CT scans. Moreover, the mobile nature of the app gives doctors the ability to analyze and diagnose strokes from practically anywhere. Read more »

Why We Need Both Primary Care Physicians And Sub-Specialists

An article in the March 24 NEJM called Specialization, Subspecialization, and Subsubspecialization in Internal Medicine might have some heads shaking: Isn’t there a shortage of primary care physicians? The sounding-board piece considers the recent decision of the American Board of Internal Medicine to issue certificates in two new fields: (1) hospice and palliative care and (2) advanced heart failure and plans in-the-works for official credentialing in other, relatively narrow fields like addiction and obesity.

The essay caught my attention because I do think it’s true that we need more well-trained specialists, as much as we need capable general physicians. Ultimately both are essential for delivery of high-quality care, and both are essential for reducing health care errors and costs.

Primary care physicians are invaluable. It’s these doctors who most-often establish rapport with patients over long periods of time, who earn their trust and, in case they should become very ill, hold their confidence on important decisions — like when and where to see a specialist and whether or not to seek more, or less, aggressive care. A well-educated, thoughtful family doctor or internist typically handles most common conditions: prophylactic care including vaccinations, weight management, high blood pressure, diabetes, straightforward infections – like bacterial pneumonia or UTIs, gout and other routine sorts of problems.

Medical Apps Allow Doctors To Monitor ICU Patients Remotely

We have reported in the past on AirStrip, a smartphone and iPad app that allows a mobile doctor to monitor the vital signs of patients in an obstetric ward or an ICU. The reverse, where a fixed doctor monitors multiple remote patients is now entering the mainstream and already making a difference in many patients’ lives.

In a compelling anecdote recently reported in Computerworld, a man experienced cardiac arrest while shopping and was taken to a nearby community hospital. An intensivist, monitoring from an eICU miles away, was immediately consulted. The remote doctor guided the treating physicians as they initiated unfamiliar hypothermia therapy to preserve the brain, and continued to follow the patient remotely throughout his 10 day ICU stay.  Happily, the patient had a good outcome and is quoted in the article as an enthusiastic proponent of eICUs.

How Experienced Is The Radiologist Who Reads Your Mammogram?

There’s a new study out on mammography with important implications for breast cancer screening. The main result is that when radiologists review more mammograms per year, the rate of false positives declines.

The stated purpose of the research*, published in the journal Radiology, was to see how radiologists’ interpretive volume — essentially the number of mammograms read per year — affects their performance in breast cancer screening. The investigators collected data from six registries participating in the NCI’s Breast Cancer Surveillance Consortium, involving 120 radiologists who interpreted 783,965 screening mammograms from 2002 to 2006. So it was a big study, at least in terms of the number of images and outcomes assessed.

First — and before reaching any conclusions — the variance among seasoned radiologists’ everyday experience reading mammograms is striking. From the paper:

…We studied 120 radiologists with a median age of 54 years (range, 37–74 years); most worked full time (75%), had 20 or more years of experience (53%), and had no fellowship training in breast imaging (92%). Time spent in breast imaging varied, with 26% of radiologists working less than 20% and 33% working 80%–100% of their time in breast imaging. Most (61%) interpreted 1000–2999 mammograms annually, with 9% interpreting 5000 or more mammograms.

So they’re looking at a diverse bunch of radiologists reading mammograms, as young as 37 and as old as 74, most with no extra training in the subspecialty. The fraction of work effort spent on breast imaging –presumably mammography, sonos and MRIs — ranged from a quarter of the group (26 percent) who spend less than a fifth of their time on it and a third (33 percent) who spend almost all of their time on breast imaging studies.

The Physician Exodus: When Doctors Leave Hospitals Behind

My partners and I have long struggled with the lack of specialty back-up at our hospital. Semi-rural hospitals, out of the way facilities, just can’t always attract specialists. So, we’re happy to have cardiologists every night, but understand that we only have an ENT every third night. We’re thankful to have neurologists, even if they don’t admit anyone. We’re glad to have radiologists, even if they don’t read plain films after 5PM on weekdays.

Still, I continue to scratch my head about why only three of seven community pediatricians take call, such that family physicians have to admit their patients. I was bumfuzzled that our neurologists were previously going to require us to use telemedicine for stroke evaluation when their offices were close by the hospital. (In the same year they were called in roughly three times per neurologist for urgent stroke evaluation.) That problem was resolved, thank goodness.

Now, I find that the problem has returned and grown. We will, very soon, have no ophthalmologist on call, despite the fact that we have three in the community and that they are contacted with remarkable rarity to deal with on-call emergencies. Soon, we will have no neurologist on the weekend. And the pediatric problem remains.

Of course, I’m using my local experience to highlight something that isn’t a local problem at all. It’s a national problem. All over America, specialists are relinquishing their hospital priveleges and staying in the office. Proceduralists are opening surgery centers that are free from the burdens of indigent care. Primary care physicians are allowing hospitalists to do all of their admissions.

In the process, not only are patients losing out, but referral centers are being absolutely overwhelmed. The cities and counties that lie around teaching hospitals are sending steady streams of patients, since they have fewer and fewer specialists. Those referral and teaching centers want patients, but they can’t take all of the non-paying patients, all of the complicated, or even all of the mundane patients with no local coverage. Those facilities, for all their shiny billboards and “center of excellence” marketing, will collapse. Read more »
