Trick of The Trade: Peritonsillar Abscess Drainage 2.0

Back in September of 2009 Michelle shared valuable Tricks of The Trade regarding drainage of PTA.

Today we revisit the topic and add two more tricks to avoid hitting "big red" a.k.a. the internal carotid artery.


Numero Uno: don't go in blind!

Ultrasound is a great adjunct in the diagnosis and treatment of skin and soft tissue infections. For PTA, after local anesthesia of the pharynx, the endocavitary probe a.k.a. transvaginal probe can be used to view the size and relationship of the abscess in question and the internal carotid artery.



Numero Dos: use a rubber bumper

In order to access the deep narrow cavity of the mouth without obscuring your many recommend a 3.5 inch 18-G spinal needle. An alternative to trimming the plastic sheath of the needle is to replace it all together with a rubber bumper- the top of a lavander-top-tube.

Women in Academic EM video

As a joint project between Clerkship Directors in EM (CDEM) and the Academy for Women in Academic EM (AWAEM), there is a great 11 minute video about life in academic EM. For more information, check out AWAEM's website.



This video was filmed and edited by my friend Dr. Ernie Wang (Northshore University/ University of Chicago), who also edited the video on "Diversity in EM" in 2007. This video was a joint project between CDEM and the SAEM Diversity Interest Group.

Article Review: Evaluating students using RIME method


How do evaluate medical students and residents, who are rotating through your Emergency Department? Do you have a structured framework for assessing their competencies?

Have you heard of the RIME method of evaluating learners on their clinical rotation? Dr. Lou Pangaro (Vice Chair for Educational Programs in the Dept of Medicine at the Uniformed Services University) published a landmark article in 1999 on his simple yet effective approach in evaluating medical students and residents. I had the pleasure of briefly meeting Dr. Pangaro when he gave CDEM's keynote speech in 2008.

As faculty evaluating students, we are constantly inundated with various evaluation forms and complex assessment tools. To optimize inter-rater reliability amongst evaluators, the key is to keep the evaluation simple, short, and concrete. In short - KISS - Keep It Simple Stupid.

RIME sets itself apart from other evaluation tools by standardizing the vocabulary so that we are talking about the same thing. It proposes a developmental model for novice through advanced learners. It represents a system which assesses the learner's skills, knowledge, and attitudes, based on observed behavior.

In a nutshell, a medical student's performance is classified into one of 4 categories:

1. Reporter
  • Reliability gathers accurate history and performs physical examination
  • Has basic medical knowledge
  • Adequately communicates findings
  • Average interpersonal skills with patients
2. Interpreter
  • Able to prioritize problem list based on patient complaint
  • Generates differential diagnosis list
  • Interprets data (labs, EKG, imaging) to adjust differential diagnosis list
  • Engages more as active provider for patient
3. Manager
  • Tailors plan to patient's circumstance and presentation
  • Demonstrates high-level interpersonal skills
  • Starts to educate patients about disease process and clinical course
  • Demonstrates more medical knowledge and advanced judgment in patient management plan
  • Proposes reasonable treatment plans while incorporating patient preferences
  • More adept at procedural skills
4. Educator
  • Performs at high-level in managing multiple patients
  • Practices self-directed learning
  • Able to share knowledge with others (junior residents and medical students)
  • Supervises junior trainees
  • Knowledgeable of current medical evidence

Personally, I believe that the RIME structure should correlate with particular training levels as follows:
  • Reporter - goal for medical student in first clinical year
  • Interpreter - goal for medical student in final clinical year and for PGY-1 resident
  • Manager - goal for PGY-2 resident
  • Educator - goal for PGY-3+ resident
The RIME method of evaluation demonstrated high reliability and validity when implemented in an internal medical clerkship.

Paucis Verbis card: Ascites assessment with paracentesis


A paracentesis procedure is often performed in the Emergency Department to rule a patient out for spontaneous bacterial peritonitis (SBP).
  • Do you check coagulation studies before performing the procedure?
  • How comfortable do you feel that the patient has SBP with an ascites WBC > 500 cells/microliter or ascites PMN > 250 cells/microliter?
This installment of the Paucis Verbis (In a Few Words) e-card series provides an evidence-based review of the literature on topics related to the paracentesis procedure. Especially helpful is the pooled data of likelihood ratios. Like most everything in medicine, a lab test should be used in conjunction with your pretest probability in clinical decision making, and LR's help with with this.

Feel free to download this card and print on a 4'' x 6'' index card.

Blog's one year anniversary


The blog is already one year old! What started initially as a little educational experiment has now evolved into a potentially long-term endeavor. It was initially built as a sort of personal journal of what I've learned and read about in the field of academic emergency medicine and educational technologies. Now I've it focuses on academics, clinical emergency medicine (Paucis Verbis cards), faculty and resident development, and technologies.

Here are some statistics over the past 12 months:
  • 36,085 visitors from 4,713 cities
  • Recently about 100-180 visits per day
Looking back, the most popular posts based on number of hits:

Trick of the Trade: Finding the subtle pneumothorax


Can you see the pneumothorax?

Small pneumothoraces can be difficult to detect on chest xrays. Overlying ribs, other bony structures, and soft tissue can obscure subtle findings. For a patient at risk for a small pneumothorax, you can use your digital radiology PACS system to improve your ability to spot them.

Trick of the Trade: Invert digital image of chest film

Standard digital radiography systems allow the user to manipulate images on the screen. Specifically there is an “invert image” icon.

By clicking on the button, black images appear white, and white images appear black. Using this Invert feature, bones, soft tissue, and vascular markings will be black, and lung parenchyma will be white. The pleural line of a pneumothorax, now a dark line on a white background with this inverted setting, is often better visualized using this technique.

Check out the inverted image of the CXR showing a subtle right-sided pneumothorax (just inferior to the orange arrows). If only all xrays had these arrows...

Hot off the press: Journal of Graduate Medical Education

In 2009, ACGME has launched a new journal focused on graduate medical education, called the Journal of Graduate Medical Education (JGME). For those of you with education manuscripts in need of a "home", consider this peer-reviewed journal. It publishes quarterly.

Thus far there have only been 3 issues out. Click on the links for a list of contents.

Right now if you go to the above links, it seems that all PDF articles are free for downloading.

Article Review: Impact of family presence in a code

Family presence in the ED resuscitation of a dying patient is a controversial topic. Some surveys suggest that families favor this practice and would repeat it again in a similar situation.

An article in Critical Care Medicine examines the impact of family presence on the ED personnel's actions, rather than the impact on the families themselves. Second and third-year EM residents were randomized into paired teams in simulation exercises. All resuscitations involved a cardiac arrest patient. Each team was exposed to one of three types of resuscitation groups:
  1. No family witness
  2. Non-obstructive family witness (quiet person) - quiet crying and conversation with social worker
  3. Overtly grieving family witness - loud crying, attempts to hug patient during resuscitation
Outcome measures:
  1. Length of resuscitation attempt
  2. Time to critical events (eg. intubation)
  3. Recognition of potential drug administration error
Results
  • n = 60 residents
  • The timed outcomes were compared across the 3 groups using a one-way analysis of variance.
  • There was no difference across the 3 groups when comparing # of minutes to CPR, to intubate the patient, and to making a death pronouncement.
  • "Overt reaction witness" group: Residents took longer to deliver the first defibrillation shock than the other 2 groups. Also residents delivered fewer shocks overall than other 2 groups.
Bottom line
Mortality improves with PROMPT defibrillation for ventricular fibrillation patients. Delays contribute to worse outcome. This study suggests that overtly-grieving family witnesses during the resuscitation may negatively impact process outcomes of the actual resuscitation.

Of course because this study was conducted on residents (not attendings) and on a human simulation (not on actual patients), more studies need to confirm these preliminary findings.

Paucis Verbis card: Appendicitis - ACEP Clinical Policy


Appendicitis is a common presentation in the Emergency Department. Dilemmas arise when deciding whether to image patients with equivocal symptoms and WBC lab results. Given the risk of ionizing radiation with CT scans, we should ideally minimize the number of CT scans ordered in these patients without mistakenly sending patients home with an early appendicitis. A perforated appendix places the patient at risk for bowel obstruction, infertility (in women), and sepsis.

Where does the American College of Emergency Physicians (ACEP) stand on the critical issues surrounding the evaluation of appendicitis?

This installment of the Paucis Verbis (In a Few Words) e-card series reviews the ACEP Clinical Policy on Appendicitis. In the end, the policy conjures up more questions than answers, but a comprehensive presentation of the literature to date and helpful risk-stratification data are provided.

I'm curious, what protocol do you use for your CT scans for ruling out appendicitis? What combinations of PO, IV, and PR contrast do you use, if any? At our site, we use PO and IV contrast.

Hot off the press: Adobe Captivate available for Macs!

Adobe Captivate, an industry-standard e-presentation software, is now available for the Macintosh! Although I have not personally used it, I have watched some instructional videos and a live demo of it today. Impressive capabilities to design polished presentations with video, audio, quizzes, and user-triggered buttons.

It costs a steep $800 for the software, but costs only $299 if you have an academic discount. You can also download a free trial for 30 days from the Adobe site.

Here's a glimpse at what Captivate can do - a cool cooking instructional module.

Anyone use this software? Any thoughts?

Trick of the Trade: Double staple gun

How do you approach the repair of scalp lacerations in a child? What factors are you considering?
  • Is the wound suspicious for child abuse?
  • Procedural sedation versus local anesthesia of the wound
  • Staples versus hair apposition technique (HAT trick) for wound closure
This trick of the trade pearl addresses the stapling technique for scalp laceration repair. Perhaps the child's hair is too short for the HAT trick.

Many scalp lacerations in pediatrics presenting to the Emergency Department can be repaired with two staples. If you've ever stapled an awake child's scalp laceration, you probably have experienced a significant delay after placing the first staple. No matter how well you attempt to anesthetize the scalp locally, the patient still likely experiences some discomfort. In general scalps are difficulty to completely anesthetize. Both pain and anxiety make it difficult to calm and immobilize the child before placing that second staple.

Trick: Double Staple Gun Technique
For patients with a small scalp laceration only requiring 2 staples, I recruit an assistant with a second staple gun. We both line up the staple guns along the scalp laceration (see photo). After we agree on the positioning, we angle the staple guns directly perpendicular with the scalp.

"3 - 2 - 1 - GO"

Both staple guns are fired simultaneously to yield a completely closed scalp laceration. While it is a less efficient use of equipment, you can tell the patient (and the family) that the procedure is over. No need to chase the patient around the room for the second staple.

Sketchcasting on What Drives Us

I recently came across a new means of online teaching and information delivery called sketchcasting. The premise isn't new. It combines a podcast (someone speaking) with visuals (images). In sketchcasting, the images are instead someone drawing on a virtual whiteboard in real-time to convey information.

I recently found a sketchcast with stop-motion and speed-up effects, which really made the presentation dynamic and super-engaging. This sketchcast by Dan Pink (Author of "Drive: The Surprising Truth About What Motivates Us") was created by the Royal Society for the Arts, Manufactures and Commerce (RSA).




Are you as amazed as I was with the sketchcasting approach to teaching (and the creator's incredible drawing skills)? This sketchcast nicely summarizes what drives many of us to pursue academics. We are looking for:
  • Autonomy - We get to work on innovative projects with relative autonomy.
  • Mastery - We get the opportunity to get better at what we do and teach medical students/residents what we know.
  • Purpose - We get the chance to improve the health of patients and help mold the physicians of tomorrow.

Article Review: Revised EM Clerkship Curriculum

Last year, I was fortunate to be involved in a 1-year consensus group building exercise in revising the 2006 EM Clerkship Curriculum. Led by my friend Dr. David Manthey (Wake Forest), members of the Clerkship Directors in Emergency Medicine (CDEM) debated and went through seemingly an infinite number of drafts of the updated curriculum.

The final manuscript was just published in Academic Emergency Medicine this month.

What we came up with was the 2010 EM Clerkship Syllabus. Four goals were addressed:
  1. Refining the objectives based on the ACGME core competencies
  2. Restructuring and refining the knowledge content
  3. Writing objectives for the procedures syllabus
  4. Identifying areas of the LCME guidelines which are addressed by the syllabus
What I'd like to highlight is #2:
Restructuring the EM clerkship's knowledge content

A major goal of the revised curriculum was to allow for an EM clerkship director to more easily cover the core content material of EM within a 4-week period. This was difficult to accomplish with the overly comprehensive original curriculum from 2006.

Basically, knowledge content was categorized into three areas:
  1. Fundamental set of emergent patient presentations
  2. Set of specific disease entities, unique to EM
  3. Procedural skills
Emergent Patient Presentations
We eliminated redundant topics and content that would likely be covered in other core clerkship rotations. This resulted in 10 emergent patient presentations that all EM students should be familiar with:
  • Abdominal pain
  • Altered mental status
  • Cardiac arrest
  • Chest pain
  • Gastrointestinal bleeding
  • Headache
  • Poisoning
  • Respiratory distress
  • Shock
  • Trauma


Specific disease entities include:
1. Cardiovascular
  • Abdominal aortic aneurysm
  • Acute coronary syndrome
  • Acute heart failure
  • Aortic dissection
  • DVT / pulmonary embolism
2. Endocrine / Electrolyte
  • Hyperglycemia
  • Hyperkalemia
  • Hypoglycemia
  • Thyroid storm
3. Environmental
  • Burns / smoke inhalation
  • Envenomation
  • Heat illness
  • Hypothermia
  • Near drowning
4. Gastrointestinal
  • Appendicitis
  • Biliary disease
  • Bowel obstruction
  • Massive GI bleed
  • Mesenteric ischemia
  • Perforated viscous
5. Genito-urinary
  • Ectopic pregnancy
  • PID / TOA
  • Testicular / ovarian torsion
6. Neurologic
  • Acute stroke
  • Intracranial hemorrhage
  • Meningitis
  • Status epilepticus
7. Pulmonary
  • Asthma
  • COPD
  • Pneumonia
  • Pneumothorax
8. Psychiatric
  • Agitated patient
  • Suicidal thought/ideation
9. Sepsis


Basic Understanding of Procedural Skills
Note that for basic procedures, students need to demonstrate basic skill competency. For more advanced skills (joint relocation, endotracheal intubation, FAST ultrasonography in trauma), students need to demonstrate a basic understanding of the skill.
  • Peripheral Access
  • Airway Management
  • Arrhythmia Management
  • NG tube placement
  • Foley catheterization
  • Dislocations and Splinting
  • Incision and Drainage
  • Trauma Management
  • Wound Care
For more specifics, download the article and the 3 online supplements which detail the entire EM clerkship curriculum.

Hot off the press
Preliminary online "chapters" of the emergent patient presentations and specific disease entities, which follow this 2010 EM clerkship syllabus template, can be found on CDEM's curriculum website: www.cdemcurriculum.org. This site may become the free, go-to online textbook for EM clerkship students. This site will also eventually host my online DIEM (Digital Instruction in Emergency Medicine) cases, which were indirectly referenced in this article as adjunctive "online interactive learning modules".

Paucis Verbis card: Septic Arthritis


In the workup of monoarticular arthritis, the question that emergency physicians constantly struggle over is whether the patient has a nongonococcal septic arthritis. This joint infection alarmingly damages and erodes cartilage within only a few days.

This installment of the Paucis Verbis (In a Few Words) e-card series reviews the JAMA Rational Clinical Examination article which asks "Does this patient have septic arthritis?" Pooled sensitivities and likelihood ratios were calculated. These statistics are always helpful when trying to figure out the patients probability of having a septic joint.

Trick of the Trade: Finding the femoral vein by V-technique


I rarely access the femoral vein for central venous catheterization... except in medical or trauma resuscitations. Oftentimes in these resuscitations, there are too many people near the IJ or subclavian vein site. People are intubating, performing CPR, trying to get peripheral vein access, etc.

The patient's femoral veins are relatively accessible areas. Use the ultrasound if it is readily available to you and is easy to maneuver between providers to reach the patient. For me, the ultrasound machine is often too large and unwieldy to wedge between providers.

Choosing a font


When speaking to a graphic designer or graphic artist, I found that font selection is a major decision in any product. Once I innocently asked, "What's your favorite font?" The answer started with "Well it depends..." One hour later, I still didn't have an answer.

Article Review: Conceptual Model on Learner Reflection


Reflective journals and electronic portfolios are becoming increasingly popular within undergraduate and graduate medical education. I'm starting to be a believer in this learning approach, which teaches learners about professional development and life-long learning principles. Academic Medicine just published a great qualitative paper proposing a conceptual model for reflection.

What is "reflection"?
In an Medical Teacher article by Sandars, the author defines reflection broadly as:

"a metacognitive process that occurs before, during and after situations with the purpose of developing greater understanding of both the self and the situation so that future encounters with the situation are informed from previous encounters."

SAEM 2010 (June 2-6, 2010)


The Society of Academic Emergency Medicine's (SAEM) annual meeting starts this week. Instead of my regular posts, I thought I'd try using the Twitter widget to post real-time, first-hand accounts and photos from the conference.

Managing Twitter accounts - Hootsuite


Do any of you have a Twitter account? Do you have MULTIPLE Twitter accounts? As a quick, social media format, Twitter has allowed us to learn of everything in the world as it happens in real-time. This includes Gary Coleman's death, oil spills, natural disasters, ongoing conference events, and updates from the CDC.
