A 61-year-old F presents to the ED from the orthopedic clinic with acute right knee pain. She endorses that while a physical exam was being performed, she had sudden onset knee pain. Denies any trauma to the knee, radiation of pain, numbness, tingling, or swelling. The above knee radiographs were obtained (Images courtesy of John Kiel, DO).
In 2018, the American College of Physicians (ACEP) released a Clinical Policy with management recommendations for patients presenting to the emergency department (ED) with concern for non-ST-elevation myocardial infarction (NSTEMI). Dr. Jason Woods hosted an episode of the ACEP E-QUAL Network podcast highlighting key aspects of the new policy. Dr. Woods was joined by lead writer Dr. Christian Tomaszewski from the University of California San Diego, and Dr. Michael Ross, Director of the Chest Pain Center at Emory University. Below are show notes reviewing the recommendations and the process involved in creating the clinical policy.
The National Guideline Clearinghouse (NGC), a public resource initiative of the Agency for Healthcare Research and Quality (AHRQ), provides rules and frameworks for evidence-based clinical practice guidelines. ACEP refers to clinical practice guidelines in Emergency Medicine (EM) as policies to denote the more prescriptive design process.
Development of the 2018 ACEP NSTEMI Clinical Policy was a 2-year “labor of love.” Writers, methodologies, and committee members were required to be free from both financial and intellectual conflict of interest.
The clinical policy is a result of a systematic review and critical analysis of available medical literature. Clinical studies were graded on robustness, design, and class of evidence according to the ACEP policy development process which includes internal and external review.
Recommendations were categorized as reflecting high clinical certainty (Level A), moderate clinical certainty (Level B), or mixed clinical certainty (Level C) due to the heterogeneity of results, unclear effect magnitude, bias, among other factors.
Four critical questions were decided by consensus methods to address the evaluation and management of adult patients presenting to the ED with concern for NSTEMI.
1) If ST-elevation myocardial infarction is excluded, can a combination of bedside and laboratory evaluation in the ED identify patients at low risk for major adverse cardiac events (MACE)?
Level B recommendation: History, ECG, Age, Risk Factors, Troponin (HEART) score < 3 can be used as a clinical prediction tool for a 30-day MACE miss rate between 0-2%.
Level C recommendation: Thrombolysis in Myocardial Infarction (TIMI) score can be used to predict risk of 30-day MACE.
2) Can repeat Troponin testing in the ED be used to identify patients at low risk for MACE?
Level C recommendations:
3) In patients who have been ruled out for acute coronary syndromes (ACS), does advanced cardiac provocative testing prior to discharge from the ED reduce MACE?
Level B recommendation: Do not routinely use advanced cardiac testing in low-risk patients who have been ruled out for ACS to further reduce 30-day MACE.
Level C recommendation: Arrange follow-up in 1-2 weeks for low-risk patients in whom ACS has been ruled out. If unable to arrange follow-up, consider observation and advanced testing prior to discharge.
4) Should patients with NSTEMI receive antiplatelet therapy in addition to aspirin in the ED?
Level C recommendation: P2Y12 inhibitors and glycoprotein IIb/IIIa inhibitors can be given in the ED or delayed until cardiac catheterization.
The 2018 ACEP Clinical Policy for NSTEMI was written for the evaluation of patients with suspicion for ACS who presented with chest pain. It does not apply to those presentations of ACS that are considered atypical in nature.

Building on already increasing interest in telehealth, the COVID-19 pandemic accelerated the development and implementation of telemedicine services in a variety of clinical settings. In 2018, Dr. Jason Woods hosted an episode of the ACEP E-QUAL Network podcast highlighting the creation of an electronic intensive care unit (eICU) through Emory Healthcare. In this episode, Dr. Tim Buchman and Critical Care Nurse Cheryl Hiddelson share their innovative approach to delivering critical care services via telehealth. We present highlights from this discussion below.
The eICU allows for critical care oversight, without having to be on site. It provides comprehensive monitoring and data analysis and online audio or video support for patients and families. Utilizing advanced information technology (IT) platforms and approaching with a business strategy, telehealth allows for innovative ways to provide critical care services remotely.
The US population is aging, with the number of Americans age 65 or older increasing steadily. Demand for critical care services increases with age. The availability of critical care physicians is limited in large areas of the US. Similarly, as more nurses are reaching retirement than those entering the workforce, critical care providers are becoming hard to come by. Recruiting and maintaining critical care providers is only one part of the issue, with staffing on nights, weekends, and holidays creating a constant challenge. Telehealth poses a contemporary solution to the scarcity of healthcare providers.
The eICU is akin to airline control towers. There is 24/7 coverage by nursing and physician staff, overseeing more than a hundred beds. Various screens facilitate a “sentry” role in which surveillance monitoring algorithms allow staff to detect problems possibly even before the bedside staff. The eICU integrates bedside monitor data with additional system-wide data to create different views of what is occurring in the unit being monitored. Staff can track discharge readiness and filter lists by system or condition.
Camera sessions allow for bi-directional communication with patients and families, but also for just-in-time-training with staff as well as consultation with specialists.
The Emory eICU was able to realize decreased mortality, decreased transfer rates, decreased length of stay, and an increase in patient experience metrics for the hospitals it covered compared to other local facilities. Analysis of costs suggested savings of thousands of dollars per patient and increased revenue for small community hospitals that could retain and increase their daily census of critical care patients.
There may be a role in applying telehealth data monitoring to emergency department waiting rooms in an attempt to identify patients at high risk for sudden deterioration or decompensation.

A major development in curbing the opioid epidemic is the introduction of the medication buprenorphine to address opioid addiction. Being able to prescribe this medication, however, requires a special DEA-X Waiver in the United States. Dr. Alister Martin, the Founder of the Get Waivered initiative, is working to reduce the barriers for clinicians to obtain the training and paperwork necessary to obtain this waiver. Dr. Michelle Lin talks with Dr. Martin on this podcast about the backstory of the Get Waivered program, the lowered barriers to obtaining training, and some sneak peaks on what is new on the launching pad for his program.
Interesting fact: Medical students can participate in the free DEA-X waiver training now. The certificate of completion has no expiration date and can be submitted, when eligible for this waiver license.

A 33-year-old male presents with intermittent blurry vision and left eye pain for 3 months, and a left-sided orbital headache for 1 day. He reports getting punched in the left side of the head during an altercation a few months ago. The eye pain is worse with ocular movements and is associated with bilateral conjunctival injection and white/green discharge from the left eye.
The patient was seen at another emergency department 3 months prior for the same symptoms. He was then found to have left-sided proptosis, visual acuity 20/60 in the left eye, no fluorescein uptake, and a normal fundoscopic exam. The patient was instructed to follow up with ophthalmology but did not. The patient denies fevers, chills, dizziness, nausea, vomiting, and abdominal pain.
A 38-year-old male presents 8 days after being stung in the left foot while surfing. He reports the sudden onset of sharp pain while walking in the ocean. He was seen initially in the emergency department. The puncture wound on his left foot was anesthetized, explored, and irrigated. No X-ray was obtained, no foreign body was discovered, and he was discharged home.
Two days ago, he noticed worsening heat, itchiness, swelling, and skin changes (red bumps and patches extending from the foot up to the lower calf) in his left foot. His current pain is rated 3/10 and localized to the left foot. The patient is able to walk and bear weight. He has been taking ibuprofen for pain control and is not taking antibiotics. He denies fevers, but reports fatigue and feels more cold than usual.
13-year-old M presents to the ED with acute left knee pain that occurred about 2 hours prior to arrival while playing football. No direct trauma. Reports two audible “pops” followed by knee instability. Radiograph as pictured (Image 1. Plain film of the left knee. Image courtesy of John Kiel, DO).
Patellar subluxation. This patient likely had a spontaneous dislocation and relocation (the two “pops”). There is a very small avulsion fracture noted along the lateral femoral condyle.
It is very important to complete a full neurovascular exam. As well as performing a thorough musculoskeletal exam, assessing the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), lateral cruciate ligament (LCL), medial cruciate ligament (MCL), and patella. View the ALiEM 2 minute knee examination.
If there is an abnormal neurovascular exam or unstable knee examination, pursue further workup such as a CT scan. As an outpatient, further imaging that can be considered is an MRI knee. See below for images from this case.

This is one of the few times a knee immobilizer is appropriate. However, close follow-up with sports medicine or orthopedics should be stressed as atrophy and contractions can occur if the patient remains in the knee immobilizer for an extended duration. Provide crutches and ask the patient to be non-weight bearing. Anti-inflammatories as needed are appropriate and encourage icing and movement.
An urgent follow-up is needed with sports medicine or orthopedics for further evaluation [3]. In the case of this patient who already had an MRI, he will typically require chondroplasty of the patella and MFPL reconstruction as an outpatient. Post-operatively, he will undergo standard physical therapy with an emphasis on range of motion and quadriceps strengthening.
