Rotation 5 – Rotation Reflection

My Emergency Medicine experience at Metropolitan was one I cannot forget. I thoroughly enjoyed the variety of cases that came into the ED daily. One moment you may be seeing an undomiciled patient who simply checked into the ED to gain a meal and a bed, and the next moment the “emergency” phone will ring and all the staff is alerted to prepare to receive a patient who is an epileptic that was found unresponsive. There was never a dull moment. 

One memorable patient I will carry with me is an unidentified man who was found unresponsive in his car. His initial rhythm was asystole, and CPR was started on the field. ROSC was obtained prior to arrival in the ED, but he lost his pulse again upon arrival to the trauma bay. We resumed CPR, and eventually brought him back. However, the patient had fixed and dilated pupils, which led us to believe he was brain dead. This case was tragic in many ways. For almost an hour, we did not know the identity of this man. He did not have any source of identification on him, nor were we able to have any way to reach out to his loved ones. Eventually, his family did find their way to the hospital, and visited him in the ICU. In his CT scan, he was found to have a severe SAH; then we had learned that overnight he had gone into cardiac arrest again and was unable to be revived. Another aspect that broke my heart was wondering what was going on in the patient’s final moments before he lost consciousness. Was his status deterioration quick? Did he have any idea his health was under threat? Was he in pain? What did he have planned for the night? It saddened me to think he was alone and dying, and that we may never get answers to these questions. 

This rotation had similarities and differences with my other rotations. There were the patients who came in with common complaints which I have come across prior. For example, those with lower back musculoskeletal pain commonly seen in my Family Medicine rotation; those with a possible fracture as seen in Ambulatory Medicine; and vaginal bleeding in pregnant women as seen in my OBGYN rotation. It was great to see some overlap in the types of cases, which I believe help me better practice my history taking in them. What differed from my other rotations was the severity of cases that may arrive in the ED. The complaints that are more acute and stressful to the patient, end up being seen in this specialty. For example, someone with a small laceration on the arm may walk into Ambulatory care, but if that laceration was extremely deep, with unstoppable bleeding, and the patient experienced a loss of movement or sensation, they would most likely elect to go to an ED. 

Working in this ED showed a different way of managing patients. I was used to how Family Medicine worked to find out all of patients’ problems and addressed them. However, I learned that this was not the goal in emergency medicine. We need to rule out life-threatening/altering and limb-threatening differentials. After that, patients were cleared and sent home with referrals to follow up with outpatient specialties. For example, there was a young patient who came in with anemia and lower abdominal pain. A stool guiac was performed on the patient, which turned out positive. I was amazed that since the patient was not in any distress, did not have any comorbidities, and her vital signs were stable, she was simply discharged and instructed to follow up another day with GI. It was shocking to me, since after hearing about positive guaiacs in school, I felt pressured to find out the source of the bleeding. 

Prior to this rotation, I had my sights on working in surgery. However, after this rotation, emergency medicine was making its way up to the top 3 of my list. I hope that my preceptor and colleagues saw that I was enthusiastic to learn about this specialty. The work environment was exciting, and the staff added even more to the experience with their love of medicine. At first I was anxious about the rotation, since I could not predict the next patient and scenario that would walk through the door. I was nervous that patients coming to the ED “on the worst day of their life” would not want to talk to students, let alone get procedures done by students (ie: IV, foleys, head staples); however, I was pleasantly surprised by most of the interactions I had. After introducing myself as a student working in their medical team, most of the patients were happy to be seen and willing to work with us.

Rotation 5 – Site Evaluation

My Emergency Medicine site evaluation was held with me and two classmates. On the first day, I presented my H&P on a patient who came in with pain that radiated from his back, to his general abdomen, and then to his epigastric region; with associated nausea and vomiting. It was an interesting case because we initially sent the patient home with a vague diagnosis of musculoskeletal pain with gastritis. The patient had returned a few days later, complaining of more severe pain, and was finally diagnosed with an H. pylori infection and bleeding duodenal ulcer. When looking back on the original visit, he did have an elevated WBC count and anemia that was not directly addressed. On the second site evaluation, there was a case presented by my classmate regarding a patient who had initially visited the ED complaining with abdominal pain and hematuria, and was diagnosed with a UTI. Two weeks later, he had returned to the hospital after his family and friends informed him that he was looking jaundiced. A CT scan was performed, which revealed cancer at the head of the pancreas. 

These were unfortunate stories of missed diagnoses in medicine. However, they reminded me of an EM podcast I listened to. It had described that not all abdominal pain complaints will be diagnosed within the first visit, and that subsequent visits with progressing symptoms often lead to the final diagnosis. I think it also taught the lesson that us, as providers, need to not only be good at diagnosing “horses”, but also look out for the “zebras”.

Rotation 5 – Journal Article

In patients presenting to the emergency department with skin and soft tissue infections what is the diagnostic accuracy of point-of-care ultrasonography for the diagnosis of abscess compared to the current standard of care? A systematic review and meta-analysis

During my Emergency Medicine rotation, I had seen the treatment of an abscess that had formed in the upper inner thigh of a young diabetic patient. The affected area already had a cavity from which it drained, but there was still a tender and hard surrounding area. The resident I worked with was having difficulty figuring out the extent of the abscess and breaking up any loculations. I could not help but to wonder if there was an easier way to visualize the presence of the abscess underneath. I came across an article titled “In patients presenting to the emergency department with skin and soft tissue infections what is the diagnostic accuracy of point-of-care ultrasonography for the diagnosis of abscess compared to the current standard of care?”. 

This article was a systematic review and meta-analysis. The objective was to determine the accuracy of POCUS in diagnosing abscesses in patients with skin and soft tissue infections, and the setting was held in emergency departments. PubMed, Medline, Embase and Cochrane databases were searched, and 8 articles met the inclusion criteria, and were selected. A total of 747 subjects were included, 3 from adult ED and 5 from pediatric ED. The quality of these articles were rated good to excellent, according to QUADAS (Quality Assessment of Diagnostic Accuracy Studies) tool. They articles included in this study had their estimated sensitivity and specificity values plotted on a graph.It was estimated that POCUS had a 96.2% sensitivity and 82.9% specificity in diagnosing abscesses. There was a positive likelihood ratio of 5.63, and negative likelihood ratio of 0.05. Five studies had looked into whether POCUS findings impacted management of patients, in terms of whether or not to perform drainage. In pediatric patients, the rate of change ranged between 14-27%; while in adult patients, it was between 17-56%.

The findings showed that POCUS was a good tool to use in Emergency Medicine to identify the presence of abscesses. It also is helpful to influence the direction of management for these patients.
