The Changing Paradigm of VTE Care

The EMBER Project is having a good day. Despite the cold and snow on our first day of spring, it’s also the first of what I hope will be many new broadcasts using the Google+ platform.  I’m excited about the potential of adapting this tool for medical education. In an era of specialty care, disease entities intersect with multiple disciplines, and optimal care often requires a collaborative approach.

Venous Thromboembolism is one of those diseases that crosses most specialty boundaries. I was lucky enough to get Dr Akhilesh Sista to talk about the changing paradigm of VTE management, and to answer my questions about novel oral anticoagulants, endovascular interventions for post-thrombotic syndrome, and who needs a hematology referral. There are lots of great pearls in this talk. You can view it from the Youtube link above or here on the Event page which will give you the show note links to other great bundled educational material.

The EMBER Project reflects my interest in technology’s ability to enhance the culture of learning and expand our conception of a community of medical educators. Blogs, podcasts, and other social media platforms continue to break down traditional institutional and geographic boundaries, and Google broadcast is another tool that’s especially suited for multi-disciplinary discussions on common disease entities when a team-based approach that does away with traditional specialty care boundaries just makes sense. I’m optimistic we are working towards a time when there is no “upstairs care” or “downstairs care” only good care everywhere.

I hope you enjoy this first broadcast. Please forgive any technical flaws as I work out some of the kinks. Thanks again to Dr. Sista for being such a good sport!


Surgical Airway Summary

tumblr_m4shyetv9g1r3fh2ko1_500_large

Our online walkabout on the emergency surgical airway is coming to an end. I hope you’ve found this helpful, I know I enjoyed doing it. The emergent cricothyroidotomy presents many educational challenges. It is a high stakes, low-frequency procedure performed in the stressful failed airway situation, where time is not on your side.

Preparing yourself for this scenario requires several key technical and non-technical skills outlined in summary here:

  • A working knowledge of airway anatomy and the confidence to quickly identify important anatomical landmarks.
  • Familiarity with the necessary procedural skills – ideally practiced and reviewed in cadaver as well as sim labs so that the muscle memory is there when you need it.
  • Situational awareness: a term that encompasses the logistical, emotional and psychological skills necessary to take appropriate and effective action. In this case it is defined by how effectively you can identify the failed airway and move through the failed airway algorithm in order to put scalpel to skin. It includes the recognition of normalcy bias and focus lock and the danger of repetitive attempts at laryngoscopy to the hypoxic patient,

This exercise is not a substitute for good clinical training, rather it is designed to highlight key concepts by drawing together disparate online resources into a coherent and educational narrative. As the name EMBER Project (EM Bundles & Education Research) suggests, our goal is to provide bundles of educational material and to discover innovative ways to bring it to you. This time. the entire bundle of resources presented over the last couple of weeks, along with commentary and opinions from other physicians and experts will be up on the EMBER Project’s Facebook page and on Storify today for review – and for future reference. Please join the conversation and add your insight. Until then, may the airway be ever in your favor!

Who are the stewards of healthcare?

Economist-Healthcare-Spending-Waste-Chart

I met a father yesterday in our ED who didn’t want antibiotics for his child’s otitis media.  He had read that a wait and see approach with appropriate analgesia might be a better option, and I was reminded that better stewardship of our healthcare is everyone’s concern.  It made me so happy to see a parent making such an informed choice, rather than thinking to myself (as I sometimes do) about how bad my Press Gainey score was going to be for being “the idiot doctor who didn’t want to give my child antibiotics for an ear infection”.

Our healthcare system is like recycling, carbon emissions or government spending: everyone agrees we should do more with less and be better stewards in theory, but when it comes to practice it’s always someone else’s problem. Is it because the system is so large we don’t feel that our actions matter, or do we feel entitled to use the resources we have, even if they offer no clear benefit to our patients? I don’t know the answer to this, but I do know that I still do unnecessary tests everyday in the emergency department.  Some are because of my concerns over missing disease in low risk patients, some are because I’m following “standard of care” or “best practice” based on poor evidence, some are because specialists want them or won’t admit or see the patient without them, sometimes its the end of my shift and it’s the path of least resistance.

The list of why unnecessary testing occurs is long and the vigilance required to stay on course and do what I think is right for each individual patient and the healthcare system as a whole is enormous.  In fact I would say a large percentage of my education time and practice is devoted to this one task.  The difficulty is in finding the support and resources to continue the process of informed and judicious use of medical resources against the onslaught of demands made by an avaricious, RVU/procedure driven, and risk averse healthcare industry.

The New York Times posted on a great resource for both patients and doctors that I believe is worth mentioning.  It is a list of the most commonly overused tests in seventeen different medical specialities.  Emergency Medicine is not one of the specialties listed (although it should be), however there are many emergency department relevant tests listed among the various specialty lists. I find this resource particularly helpful in stemming the tide of what other specialists ask of me in my Emergency Department (like PPI for GI bleed or pre-op echoes in cardiac patients) and in making decisions for why I’m admitting a patient.  If my major reason is an expedited workup with one of these unnecessary tests then perhaps I will think twice.

For example here are the top five recommended DON’Ts from the American College of Radiology:

1. Don’t do imaging for uncomplicated headache.

Imaging headache patients absent specific risk factors for structural disease is not likely to change management or improve outcome. Those patients with a significant likelihood of structural disease requiring immediate attention are detected by clinical screens that have been validated in many settings. Many studies and clinical practice guidelines concur. Also, incidental findings lead to additional medical procedures and expense that do not improve patient well-being.

2. Don’t image for suspected pulmonary embolism (PE) without moderate or high pre-test probability.

While deep vein thrombosis (DVT) and PE are relatively common clinically, they are rare in the absence of elevated blood d-Dimer levels and certain specific risk factors. Imaging, particularly computed tomography (CT) pulmonary angiography, is a rapid, accurate and widely available test, but has limited value in patients who are very unlikely, based on serum and clinical criteria, to have significant value. Imaging is helpful to confirm or exclude PE only for such patients, not for patients with low pre-test probability of PE.

3. Avoid admission or preoperative chest x-rays for ambulatory patients with unremarkable history and physical exam.

Performing routine admission or preoperative chest x-rays is not recommended for ambulatory patients without specific reasons suggested by the history and/or physical examination findings. Only 2 percent of such images lead to a change in management. Obtaining a chest radiograph is reasonable if acute cardiopulmonary disease is suspected or there is a history of chronic stable cardiopulmonary disease in a patient older than age 70 who has not had chest radiography within six months.

4. Don’t do computed tomography (CT) for the evaluation of suspected appendicitis in children until after ultrasound has been considered as an option.

Although CT is accurate in the evaluation of suspected appendicitis in the pediatric population, ultrasound is nearly as good in experienced hands. Since ultrasound will reduce radiation exposure, ultrasound is the preferred initial consideration for imaging examination in children. If the results of the ultrasound exam are equivocal, it may be followed by CT. This approach is cost-effective, reduces potential radiation risks and has excellent accuracy, with reported sensitivity and specificity of 94 percent.

5. Don’t recommend follow-up imaging for clinically inconsequential adnexal cysts.

Simple cysts and hemorrhagic cysts in women of reproductive age are almost always physiologic. Small simple cysts in postmenopausal women are common, and clinically inconsequential. Ovarian cancer, while typically cystic, does not arise from these benign-appearing cysts. After a good quality ultrasound in women of reproductive age, don’t recommend follow-up for a classic corpus luteum or simple cyst <5 cm in greatest diameter. Use 1 cm as a threshold for simple cysts in postmenopausal women.

The other seventeen lists are just as good and have a great deal of information relevant to our daily practice.  Of course no list trumps clinical judgement.  The environment we work in, the prevalence of a certain disease in our community, the quality of our tests, and our testing threshold should ultimately determine what we order and what we don’t, but having the support of other specialty societies to NOT do tests is a welcome resource. Along with sites like The NNT and EMLITofNOTE it is another tool to continue improving our daily practice.

Case Reports from the ED

The EMBER Project.002

Note the subtle venous congestion and edema of the right hand and wrist in this patient with an upper extremity deep venous thrombosis (Paget-Schroetter Disease),

Here is a slightly different twist on Virchow’s triad, and one that I had not seen before until yesterday:  a spontaneous upper extremity DVT (Paget Schroetter Disease) in an otherwise healthy person with no risk factors.  It’s uncommon, but not a complete zebra.  The pathophysiology and subsequent management also differs from your traditional DVT, so I thought it was worthwhile to highlight some of the features that make it unique.

Postcards from the ED

Upper Extremity Hematoma

I was going to use this post to talk about potential spaces in the body until I made the mistake of mentioning it to a surgical friend of mine (yes, I have them) who got all upset that I was really talking about a compartment and not a potential space (apparently I’ve been inappropriately mixing anatomical spaces my entire career). While the definition of a compartment versus a potential space is still debated hotly among anatomy nerds (yes I called you a nerd), for an EP there’s nothing like a dramatic case to remind you that not all potential spaces (or compartments or whatever, hey will you relax please?) are created equal.The elderly and morbidly obese often have a lot more “potential” to extravasate into these spaces.

In the case pictured here, a minor fall in a small woman with abundant loose adipose tissue in her arms led to substantial blood loss before spontaneously rupturing through the skin. She arrived to the ED in class III hemorrhagic shock.

So I guess if you want to be clear about it, old people on Coumadin have a lot of “potential” to bleed copiously into what seem like rather small compartments.  Okay there, does that make you happy?  I know it does.

If you would like to review the difference between a compartment and a potential space here is a mind-numbing review for you. Anatomical spaces: a review. Newell RL. Anatomy Unit, School of Biosciences, Cardiff University, UK. Newell@cardiff.ac.uk

Evernote Meet Google

 

Maybe it’s a hold-over from my childhood days, but September is the month of organization.  You know, the ritual purchasing of three-ring binders, pencil holders, graph paper, all with the hope and optimism that this year things will stay organized.  Inevitably by the end of the year you’re digging around your overstuffed backpack for that piece of paper with the homework assignment on it.

Now instead of three-ring binders I hoard information online: downloading, tagging, and clipping, all in the vain hope that it will stay organized for some future use. And why not.  I spend a lot of time reading and searching online for emergency medicine information for my particular learning needs. Unfortunately, most of it collects digital dust on my hard drive or cloud – the junk drawers of the digital age.

So here is a great new tool that is actually getting me to use the information I’ve already collected.  Evernote meet Google.  Evernote now allows you to simultaneously search Google and your Evernote folder on any web browser.  Want to review subtle ECG findings suggestive of STEMI?  Type STEMI into Google and it gets you 1,700,000 hits, but now it also gives me 3 notes from my Evernote account.  Since I’ve already clipped these to my account the likelihood that they are valuable to me at the moment I want it is high.

Sure enough clicking on the Evernote icon shows me I have an article from Amal Mattu about high risk ECGs, a review of subtle STEMI patterns by Dr Smith from his ECG blog, and a link to another good online ECG education site.

Wow, my preselected information side by side with the power of Google, all at my fingertips on a web browser.  Finally, I’m ready for school (can I redo fifth grade please)?
