Diminishing Returns: The "MIC Creep" Dilemma with Vancomycin


Accuracy

Valid for practice

True to literature

Overall quality


Please peer-review this blog post by clicking on the stars above.

The story of vancomycin all started when a missionary from Boreno sent a sample of dirt to a friend at Eli Lilly. The compound isolated had activity against most gram positive organisms. In fact, it got its name from the word 'vanquish.' Vancomycin was FDA-approved in 1958. [1]

Vancomycin is still a powerful tool against gram positive organisms, but there are some important learning points for using it properly in the critically ill ED patient.


First, a little history...

The original minimum inhibitory concentration (MIC) cutoff for S. aureus susceptibility was  4 mcg/mL. This was decreased to  2 mcg/mL in 2007 despite the emergence of vancomycin intermediate S. aureus (VISA). [2] Remember, MIC is the lowest concentration of an antimicrobial that will inhibit the visible growth of a microorganism after overnight incubation (thanks Wikipedia). MICs can vary based on testing method utilized (by 1-2 fold).

What is MIC Creep?

Over time it seems the MIC needed for vancomycin to eradicate MRSA is increasing, as evidenced by increasing vancomycin MIC distribution in S. aureus isolates. [3] 



What's the problem?
Patients are dying from bacteremias even with MICs  2 mcg/mL that appear as 'susceptible' on institutional reporting tools. This is scary!
  • Vancomycin MIC of 2 mcg/mL was an independent predictor of mortality. [4]
  • MIC break point  1.5 mcg/mL was associated with an increased probability of vancomycin treatment failure. [5]
These two findings were verified by a systematic review/meta-analysis. [6] The authors also found that vancomycin treatment failures and mortality for MRSA infections occurred regardless of source of infection or MIC testing methodology!

What it all means
Although in the ED we often don't have access to the patient's susceptibility data, make sure to look at previous records from your institution or the transferring institution. Just because the culture report says 'S' (for susceptible), the MIC may be between 1.5 and 2 mcg/mL.
  • For bacteremias/endocarditis: if the S. aureus MIC  1.5 mcg/mL, don't use vancomycin!
  • For all other MRSA infections: if the S. aureus MIC  2 mcg/mL, don't use vancomycin!
Proper Vancomycin Dosing in the ED [7]
  • Stop using a default dose of 1 gm for all patients. Vancomycin is dosed based on total body weight.
  • An initial dose of 15-20 mg/kg should be started in the ED. For critically ill patients, loading doses (25-30 mg/kg) can be considered.
  • The initial dose should not be adjusted down based on renal function (we can adjust the dosing interval later).
Thanks to Emily Heil, PharmD, BCPS for providing much of the information for this post.

Mentorship: Who benefits?


Mentorship is one of the professional relationships that fascinates me the most. We've all had those people in our lives that help us advance our careers, gain more insight to our practice, guide us to a more work/life balance. Some might call these people mentors, while other call them coaches or guides. Even after completion of training or schooling, people make use of these coaches/mentors as is the case in sports or medicine. For example Atul Gawande writes how a mentor helped him improve his practice as a surgeon years after completing his training.

This relationship is very complex, but at the same time vital for a successful career. In its complexities we must find what makes it functional and nonfunctional in order to benefit from this interaction. When this relationship is successful there are four winners:
  • The mentee
  • The mentor
  • The institution to which they belong
  • Patients 
Mentees and mentors end up with better career satisfaction, career advancement, and better pay, but the relationship has to “click” in order for it to work. The institutions can benefit from improved morale, enhanced productivity, external recognition, and more. When these relationships become dysfunction, and it’s not remedied, it can be harmful to the parties involved. The study below published this past November in Academic Medicine, explores the characteristics that make these relationships a success or or a failure.

 


Fifty-four faculty members from different career streams were interviewed via telephone. Although this qualitative study has its limitations, it contains salient points that are worth considering in this complex relationship.

Characteristics
of an
effective MENTOR
Altruistic
Honest
Trustworthy
Active listener
Previous mentorship experience
Enriched network
Accessibility
Understands the potential and limitations of the mentee
Helps promote the mentee’s career


Characteristics 
of an 
effective MENTEE
Open to feedback
Active listener
Respectful to mentor’s input and time
Responsible
Pays attention to timeline
Takes responsibility for “driving the relationship”
Prepared for meetings



Actions 
of 
effective mentors
Act as guides rather than supervisors
  • Offers: advice, advocacy, network, goal setting, opportunities, how to navigate the system
Provides emotional support focusing on work/life balance
Warn mentee of potential pitfalls
Protects mentee from harsh interactions
Helps mentee have a clear vision of the career path and how interrelates with their personal and social life




Characteristics
of a successful 
mentor-mentee
relationship
Reciprocity
Mutual respect
Clear expectations
Personal connection
Shared values



Characteristics
and consequences
of a
failed mentorship
Poor communication
  • Lack of open communication
Lack of commitment
  • Lack of time or waning interest over time
Personality differences
  • Different personalities have different ways of approaching the world
Perceived (or real) competition
  • How much credit does the mentee get as opposed to the mentor?
  • When working together, it is important for the mentor to step back and let the mentee have the spotlight.
Conflicts of interest
  • The mentor should not be in a position of authority over the mentee
Mentor’s lack of experience
  • Lack of knowledge to provide advice



Tactics
for a successful
mentoring relationship
Start in the mentor’s office (a safe environment)
Establish a communication network (“reiterate and review”)
  • May use a checklist to address: career, education, administration, and personal issues
Schedule regular appointments

When the mentor-mentee relationship did not work, participants still felt that these were good life lessons. Interestingly, people in more junior positions found it more difficult to approach more senior members about the failed relationship because of the potential for bad career repercussions. Two useful podcast from the Get-It-Done Guy:


Since this is a vital process which takes part under institutions, it is being looked at more closely these days. This is a great study and gives a lot of insight into quite an interesting relationship. Although I had participated in mentorships, I was not aware or mindful of all of the characteristics mentioned here. One should be cognizant on how to continually improve the relationship. Rather than waiting until the relationship ends poorly, it is important to have a mechanism to leave the relationship under amicable terms. I hope this post motivates you to become a mentor or gives you some important points to consider when searching for that mentor or coach.

SimWars: A "warring tigers" competition

SimWars

You’ve seen this word on the agenda at the most recent Emergency Medicine conference that you attended. It sounded interesting... but you ended up going to a happy hour and missed out on the event. And so you are left with the burning question, what is SimWars?

I have now heard Dr. Haru Okuda (Director of VA SIMLEARN) introduce SimWars a few times at the start of competitions at conferences. He usually has a photo of two cute little kittens with great big sweet eyes juxtaposed with a photo of two warring tigers fighting each other. He uses this comedic relief to illustrate the difference between a standard simulation session and SimWars competition. 

A hilarious video that playfully shows the competitive nature of the competition can be seen in this clip for the upcoming Social Medical and Critical Care (SMACC) Conference in Sydney on March 11-13, 2013.  


The History of SimWars
Creators, Drs. Andy Godwin (EM Chair of Univ of Florida-Jacksonville), Haru Okuda and Scott Weingart (Mt. Sinai-NY and Emcrit.org) originally developed SimWars in response to an observed lack of urgency in response to simulated cases used in education. They watched their residents wait for the inevitable bomb to drop before actively managing the patient and thought perhaps they could build some healthy stress into the scenarios. 

In addition to providing an avenue for large group education at local, national and international conferences, SimWars allows a unique opportunity to observe the differences in how different training programs address similar situations. SimWars is also a way to showcase the utility of simulation training to more “sim-naïve” educators. It’s definitely an exciting introduction to those new to simulation.



SimWars presence at major meetings
SimWars were held at the recent SAEM, ACEP, International Meeting on Simulation in Healthcare (IMSH), and the Canadian Simulation Summit conferences. This allowed the demonstration of interdisciplinary teamwork and communication, which was the focus of such events as IMSH and the Canadian Simulation Summit. Dr. Lisa Jacobson (University of Florida-Jacksonville) has joined the SimWars team and coordinates much of the ground work.


Personal perspective
I have participated myself as a confederate and case writer.  Confederates, or “actors,” play an important role. We often are the source of important information, whether it be subtle exam findings or significant history, but just as in actual care environments, these details may be difficult to glean amidst obstructive/entertaining personalities or surrounding chaos. It is the confederates’ role to provide a balance between chaos and flow, helping to move the case quickly forward to adhere to the short time periods necessary for a competition. 

Case writing is also a fun challenge. We get to brainstorm all the possible ways a team may respond to the case and how to create manageable barriers for them to overcome. You don’t want the case to be too easy, nor do you want the case to be impossible. Most importantly there should be specific educational goals. Watch out for those twists!



Bottom line
Ultimately, I have found SimWars  to be an unique educational platform, which balances the entertaining and the challenging. There are plenty of opportunities to learn and educate, whether you are a judge, a sim team member, confederate, or case writer.

Join me at the next SimWars competition in Orlando, FL at the IMSH Simulation conference (Jan 26-30, 2013)!

Special thanks to Dr. Lisa Jacobson for her help and contribution to this blog write up.

New Years Resolution: More teachable moments please


The worst thing about busy shifts is that I never learn anything.

My junior resident and I were contemplating the many difficulties of residency, especially when working at a busy urban ED where patients are plenty, but teaching during shifts may be harder to come by. We discussed the importance of coming up with at least one learning point or clinical question during each shift, and making a point of following through and reading up on it after.  (That shift we both learned about fat emboli s/p extremity fracture.)

But even with self-initiated learning adventures, I think that it is important that faculty and senior residents take the lead and actively work to ensure that learning occurs for every resident and every medical student during every shift, throughout all years of residency. Some educators actually say that something can be taught on just about every case seen with a resident if approached correctly.


2013 New Years Resolution:  
Create 1 teachable moment, for every resident and every medical student, during every shift!

Wait! 
Dont get overwhelmed with that resolution. 
It is completely do-able!

What is a teachable moment, and how to teach for that moment?  First off, a teachable moment is exactly that, A TEACHABLE MOMENT! Not hour, not lecture, not thesis statement. But, by allowing the thought of the teaching to overwhelm the teacher, we create mountains and mental barriers. How often have we felt that it was too exhausting to explain to the junior the intricacy of the discriminate zone of beta-hcgs regarding work up of ectopic pregnancies, especially with a wait time over 6 hours?

I remember one attending that I worked with who would actually write down a checklist of three items for every patient that I would present to him. This checklist was not a To-Do list, but instead was solely dedicated to three learning points that he wanted me to have for each patient that I presented to him. We all know about the checklist manifesto for getting tasked completed why not a checklist manifesto for teaching points?

I asked a few experts via Twitter for their thoughts on teachable moments.



Dr. Mallemat (@CriticalCareNow) and Dr. Gharahbaghian (@Sonospot) mentioned that bedside ultrasound is a great opportunity to not only teach about pathology, but also anatomy!  Which means it is perfect for teaching the medical student at the beginner level, and all the way up to senior resident at expert level.  

@TheSGEM felt that ALL moments were teachable moments.  

@BobStuntz stated that the key is to limit the teaching moment to 1 pearl or point only.  Think back to when you learned about that topic. Was there a learning point or pearl that stuck out for you?  If so, focus on that point during your short discussion.

There is a caveat to all of this dont forget that we all are in a constant state of learning, even if we dont appear to be so. A senior resident once told me  it was particularly difficult to learn anything during shifts because attendings were so willing to defer to her judgment. This is a great amount of responsibility, but always remember that as doctors, there is always room for more.

Lets resolve to bring more learning and teaching on! 

Happy New Year!

P-video: How to remember the GCS scoring

New video series: P-Videos by Dr. Jeremy Faust



Welcome to the blog Dr. Jeremy Faust, who is currently an emergency medicine resident from Mount Sinai Hospital and Elmhurst Hospital Center. He's a frequent contributor to ACEP News, a proud proponent of Free Open Access Medical Education (#FOAMed), and a classical musician and producer. We extremely lucky to have Jeremy join our ALiEM blog team.

What are P-Videos?
Paucis Videos (paucis means "few" or "brief" in Latin) are short video-based educational pearls for the practicing physician with a focus on Emergency Medicine and Critical Care. The videos are meant to be extremely short so that they can be easily referred to at any time. These videos build upon concept of brevity with the Paucis Verbis ("in a few words" in Latin) cards, which provide condensed nuggets of clinical information on a 4x6 inch index card.

The P-videos take it up a notch by covering such items as:
  • Medical mnemonics
  • Instructional videos
  • "Tricks of the trade"
  • Rapid-fire journal reviews
Enjoy and please suggest topics and provide us with your feedback!

Tweet Pearls of the Week 12/7 to 12/14

To debrief or not?


Learners have limited time. Residents have work hours restrictions, practicing physicians have work / life demands, and the list goes on. Time is valuable. Therefore, educational interventions must be hard-hitting, effective, and worthwhile.

We discussed previously "What is debriefing?" Debriefing is a facilitated discussion and reflection about objectives previously chosen by the educator. Dr. Ernest Wang (NorthShore Center for Simulation and Innovation) states that it's about getting learners to that “aha!” moment.


According to Fanning and Gaba [1], deciding when to debrief is twofold:
  1. Do participants lack a sense of closure? 
  2. Can we derive useful insights through a discussion of the experience? 
Therefore, we debrief to give participants a conclusion to their learning experience, a manner by which to derive conclusions. We also debrief to provide insights as a group that may not be possible to derive as individuals.

Dr. Roger Greenaway is a UK PhD who specializes in training organizations on the benefits of active and experiential learning.  His website has published a list of 10 reasons on why to review (aka debrief).  These are some of the important points:
  • Getting unstuck: Debriefing helps the learner to progress in the cycle of learning and development. 
  • Opening new perspectives: Learners can understand complexities in medical management and realize that there is more than one right answer. 
  • Developing observational awareness: We all want to become thoughtful and observant physicians able to gather subtle patient clues and condense medical information quickly. Debriefing helps to point out missed clues.
Think of debriefing as a way of accelerating knowledge acquisition and takes learners to the next level. So it is definitely hard hitting!

This is the second of several blog posts on debriefing. Future write ups will discuss the evidence behind debriefing, debriefing techniques, and where to get formal training in debriefing.

Teaching internationally: More than just a language barrier


I recently traveled to San Salvador to help teach a pediatric and adult ultrasound course. The course was well received and it was wonderful traveling around San Salvador.

I wanted to share some of our experiences, and discuss some challenges to educating internationally. More importantly, I want to engage you, the readers to share some of your experiences when educating internationally as well.

The language
The first challenge and major road block was attempting to lecture in a foreign language. Although I studied Spanish for many years, I was definitely rusty. While I learned the history of the Argentinian Dirty War in school, I never mastered vocabulary sufficient to discuss the physics of ultrasound. We translated the majority of the presentations into Spanish by using the aid of colleagues who were from El Salvador and Google translator. Imagine how difficult this would be for languages that are not based on the Roman alphabet or if there were no native language speaking colleagues to assist. Even with that, there were still some funny hiccups.

Delivering presentations
Creating the presentations is half the battle. Delivering the presentation is even more daunting.

We all know that good lecturers don’t read off of their slides.  They can ad-lib, interact with the crowd, and make adjustments as necessary.  This becomes more difficult in another language.  No one wants to deliver a bad presentation simply because it is in another language.  Or worse, give a bizarre answer to a question because of translation issues.  I definitely practiced my presentations more than I would usually.  The butterflies in my belly before presenting were palpable!


AV equipment
A major challenge was ensuring that the AV equipment worked properly.  Although traveling with 5 other EM physicians in my group, none of us remembered to bring a dongle to connect our laptops with the AV equipment in the hospital.  Luckily, we were able to find a store and could buy the necessary missing equipment.  However, you may not always be so lucky when traveling internationally to be near an urban center.  It is important to be organized to try to limit as much AV malfunction as possible.  Remain flexible and know that there may be some level of malfunction and be prepared to address it.  Having a backup plan such as hard copies of the lecture could be life (and reputation) saving.

Ultrasound equipment
Finally there is the challenge of traveling with the portable ultrasounds internationally.
  • Customs doesn’t always know what a portable ultrasound machine is. Plus, it takes coordination to organize carry-on luggage as the ultrasound, check in your suitcase, and manage your souvenirs-- all without incurring additional travels charges.
  • Don’t forget how heavy the ultrasound machines can be on your back!  
  • Ultrasound machines are expensive. We always knew their locations to avoid losing them.
Ethical question
There was the ethical dilemma of using our high tech portable ultrasound donated by companies for international education versus using the machines that the hospitals already had.  Our equipment was definitely more advanced, but what purpose does it serve to not teach familiarity to what is available?  This is a thought that definitely can be pondered upon and argued over.


Lessons I learned:
  •  Practice, practice, and practice again when delivering a presentation that is not in your primary language
  •   Think about AV equipment - consider backups
  •   Ultrasound machines are heavy and costly
  •   Always consider sustainability
Please share any lessons you may have learned while traveling and educating internationally!

Is the 6-12-12 adenosine approach always correct?


The ACLS-recommended dosing strategy of 6 mg, 12 mg, and 12 mg for adenosine may not be appropriate in every situation. There are a few instances when lower or higher dosing should be considered.

Caveat: All recommendations are data-based, but many factors affect successful conversion of paroxysmal supraventricular tachycardia (PSVT) including proper line placement and administration technique.


Option 1: Starting at higher dose
Caffeine is an adenosine blocker and can interfere with the successful reversion of PSVT. In fact, ingestion of caffeine less than 4 hours before a 6-mg adenosine bolus significantly reduced its effectiveness in the treatment of PSVT. An increased initial adenosine dose may be indicated for these patients.

Remember that theophylline may require higher dosing as well, because it is similar to caffeine (another methylxanthine), but is not prescribed much in the U.S. anymore.

Recommended dosing strategy [1]:
  • 1st dose: 12 mg (instead of 6)
  • 2nd/3rd doses: 18 mg (instead of 12)

Option 2: Starting at lower dose
Every so often a patient arrives in PSVT with their only IV access being through a hemodialysis port. The initial adenosine dose should be reduced if administered through a central line. Remember a central line delivers the adenosine right where you need it. This recommendation is supported by the 2010 ACLS guidelines. Cases of prolonged bradycardia and severe side effects have been reported after full-dose adenosine through a central line.

Also consider lower doses in patients concomitantly taking carbamazepine or dipyridamole or in those with a transplanted heart.

Recommended dosing strategy [2, 3, 4]:
  • 1st dose: 3 mg (instead of 6)
  • 2nd/3rd doses: 6 mg (instead of 12)

The secret to patient presentations



So there’s a patient, and umm...  they are in the hallway, they came to the ED today for breathing problems, I mean dyspnea.  They also don’t speak any English.  So, uh the respiratory rate is normal, and they had a blood clot, er... I mean PE, in the past, but not on coumadin anymore.  Shoot, I forgot to tell you my exam...they had pitting edema for 3 months.  By the way, the labs came back on that other anemic patient in the other hallway, and they are really anemic...

Sounds familiar? Perhaps a medical student or intern-level presentation of a patient in the ED?  Imagine working in a hectic ED while listening to this chaotic presentation. 

What's the secret to presenting patients?

We, as attendings or senior residents, often assume that increasing knowledge will lead to improved presentations, and so focus on broadening their medical knowledge. That's only part of the solution.

What's the other part? Polishing the trainee's public speaking skills.  This is just like recommending to a lecturer that to improve their lectures, they should develop public speaking skills. In this case, the lecturer (trainee) is lecturing to an audience of one (attending).

Think of presentations as mini-impromptu speeches.  

Important qualities in public speaking:
  • Lack of fillers (um, so, uh, really, like)
  • Knowledge of content
  • Brevity
  • Organized structure
  • Eye contact
  • Subject matter of pertinence to the audience
  • Practice (go over the presentation in your head once before giving it)
As a senior resident or attending taking patient presentations, imagine a presentation that is succinct (less than 1-2 minutes), where the trainee avoids filler words, with an organized history, physical, assessment, and plan.  Imagine a presentation that does not deviate but remains true to the topic and tells a coherent story.  This type of presentation would almost be like a gentle relief in an over-stimulated ED environment.

Just as how you probably would not interrupt a good public speaker in the middle of his/her speech,  you should hold your questions until the end of their presentation. Remember this, and try to allow the trainees to finish speaking.  It may help them to keep their train of thought and structure.

For the senior resident or attending:
  • I challenge you to consider these aspects of public speaking the next time you listen to a patient presentation from a student or resident. See if you can make recommendations to improve his/her presentation style as well as the content.
For the trainee:
  • Work on being a better public speaker. 
  • As a side note, I was a part of Toastmasters International which is a nonprofit public speaking organization while in college.  Although I am no longer with the organization, I credit them with significantly improving my confidence and public speaking skills in both prepared and impromptu styles. Plus it was a lot of fun!  This is definitely something to consider if you are looking for a way to improve your public speaking skills.

Andragogy: How adults learn best

 


Andragogy refers to learning strategies which help adults to learn more effectively. It is a term that was first used by Alexander Kapp in 1833 and later expanded by Malcolm Knowles to fit the needs of adult education. The concept is contrasted with pedagogy in which the child is lead through the learning process by the teacher. In andragogy most of the learning is self-directed and the teacher is a facilitator in the learning process. 


Pedagogy is more content-oriented. 
Andragogy is more process-oriented.

This is essential in medical education due to the fact that by the time we reach medical school we are less receptive to teacher-centered education and are already in a phase where learning is more independent. Although I had already come across this concept a while ago, this concept was covered in an educator's conference put together by Rob Rogers, MD (@EM_Educator). I followed this conference via twitter and Livestream in mid-November and it was great. (Link to blog and tweets from the conference.)



Knowles identified six characteristics that motivate adult learners (1)

Need to KnowAdults need to know the reason for learning something
FoundationExperience (including error) provides the basis for learning activities
Self-ConceptAdults need to be responsible for their decisions on education; involvement in the planning and evaluation of their instruction
ReadinessAdults are most interested in learning subjects having immediate relevance to their work and/or personal lives
OrientationAdult learning is problem-centered rather than content-oriented
MotivationAdults respond better to internal versus external motivators

I think this concept should help us to become more effective educators because it provides a better look into the mind of the adult learner. It really shows that we are not satisfied when we are given a simple answer such as “because I said so” - an answer that might work with children.


Here are a few examples where you can find andragogy in medical school and residency:

  • Problem Based Learning (PBL): A group of trainees gather together to solve clinical problems. 
  • Clinical Problem Solving: This makes learning more relevant to real life experiences.
  • Trainees have different backgrounds and they bring these experiences with them to a learning group and facilitate learning.
  • When the trainee looks up information without being prompted by the trainer it shows the learner is self-reliant. 




A comparison of the assumptions of pedagogy and andragogy following Knowles (Jarvis 1985: 51) (Adapted from table)



Pedagogy
Andragogy
LearnerDependent. Teacher directs what, when, how a subject is learned and tests that it has been learned.Moves towards independence.
Self-directing.Teacher encourages and nurtures this movement.
Learner’s experience Of little worth. Hence teaching methods are didactic.A rich resource for learning. Hence teaching methods include discussion, problem-solving etc.
Readiness to learnPeople learn what society expects them to. So that the curriculum is standardized.People learn what they need to know, so that learning programmes organised around life application.
Orientation to learningAcquisition of subject matter. Curriculum organized by subjects.Learning experiences should be based around experiences,since people are performance centred in their learning.

Of course this concept is not without its criticisms and even Knowles recognized that this concept can also apply to children. It is clear that when we reach adulthood we should move to a more learner-oriented system and move away from teacher-oriented system. In the end during our training the learning process is a team project where the exchange of information can be interchanged between the trainer and the trainee. After training it is still our responsibility to become independent effective learners and stay up to date with the medical literature. If these concepts are applied effectively during our training the process will help us to become more effective long life learners. 


I would love to read your comments on this topic. Are you a content-oriented, a process-oriented, or both type of learner?
