In 2014, the CDC reported that UTI antibiotic treatment was avoidable at least 39% of the time. Why? Over-diagnosis and treatment results from the fact that asymptomatic bacteriuria is very common in all age groups, urine cultures are frequently ordered without an appropriate indication, and urinalysis results are often misinterpreted. Think of the last time you prescribed antibiotics to a patient for suspected UTI – what convinced you that they had a UTI? Was it their story? Their exam? Or was it the urine dip results the nurse handed to you before you saw them? Does a patient’s indwelling catheter distort the urinalysis? How many WBCs/hpf is enough WBCs to call it a UTI? Can culture results be trusted if there are epithelial cells in the specimen? Can a “dirty” urine in an obtunded elderly patient help guide management?...
EM Cases - A Balanced View on recent EM Literature with Joel Yaphe
Being an optimist, I'm constantly searching for EM literature that will change my practice in a positive way and ultimately improve the care that I deliver. The past year was filled with promising papers, some of which received a lot of attention. I'm not the only one who is biased towards craving a positive paper - so are the researchers, the journal editors and the public. We all want our field to mightily move forward!
Enter Dr. Joel Yaphe. An EM Residency Program Director at University of Toronto and an ED doc who I admire for his balanced, sensible and practical approach to appraising the literature. In this episode Dr. Yaphe, at University of Toronto's Update in EM Conference - Whistler, leads us through a few key articles from the past year including the REVERT trial to convert SVT, medical expulsive therapy for urolithiasis, steroids in anaphylaxis, and analgesics for low back pain, and discusses whether they should (or rather, should not) change our practice. He challenges authors' conclusions and questions whether the findings are relevant to our patients....
Urolithiasis is one of the more frequent diagnoses we are faced with in the Emergency Department, with an estimated 1 million ED visits due to renal colic. As such we are tasked with its diagnosis, prognosis and treatment. The following is a brief summation of the evidence regarding some of the most frequent questions encountered when diagnosing and managing urolithiasis. Four questions are answered by Rory Spiegel on this BEEM Cases.
What is the optimal initial imaging modality for the diagnostic work-up of urolithiasis?
Once the diagnosis of renal colic has been made what is the most efficacious analgesic strategy?
Is there clinical utility to IV fluid administration in the management of renal colic?
What is the use of medical expulsion therapy in the management of urolithiasis?
In this Journal Jam we have Dr. Michelle Lin from Academic Life in EM interviewing two authors, Dr. Rebecca Smith‑Bindman, a radiologist, and Dr. Ralph Wang an EM physician both from USCF on their article “Ultrasonography versus Computed Tomography for suspected Nephrolithiasis” published in the New England Journal of Medicine in 2014. There is currently a wide practice variation in the imaging work-up of the patient who presents to the ED with a high suspicion for renal colic. On the one extreme, some EM physicians use CT to screen all patients who present with renal colic, while on the other extreme, other EM physicians do not use any imaging on any patient who has had previous imaging. The role of POCUS and radiology department ultrasound as an alternative to CT in the work up of renal colic has not been clearly defined in the ED setting. This study was a pragmatic multi-centre randomized control trial of patients in whom the primary diagnostic concern was renal colic, that tried to answer the question: is there a significant difference in the serious missed diagnosis rate, serious adverse events rate, pain, return visits, admissions to hospital, radiation dose and diagnostic accuracy if the EM provider chose POCUS, radiology department ultrasound or CT for their initial imaging modality of choice. This Journal Jam is peer review by EMNerd's Rory Spiegel.

In the second part of this epic 2-part authoritative episode, Anticoagulants, PCCs & Platelets, we have Dr. Walter Himmel (also known as 'The walking encyclopedia of EM') along with Dr. Katerina Pavenski (Head of Transfusion Medicine at St. Michael's Hospital) & Dr. Jeannie Callum (Head of Transfusion Medicine at Sunnybrook Hospital) who will discuss the latest on comparative efficacy and reversal of Warfarin vs Dabigatran vs Rivaroxiban vs Abixaban, the use of prothrombin complex concentrates (PCCs), the ins and outs of thrombocytopenia & platelet transfusions, ITP, TTP, anti-platelet associated intracranial bleeds, indications for Tranexamic Acid & more...
In this bonus episode, our second installment of the highlights from Whistler Update in Emergency Medicine Conference 2012, we have Dr. Eric Letovsky talking about complications of MI and the importance of listening for cardiac murmurs. Next, I moderate an expert panel on the current trends on imaging patients who present with renal colic and query appendicitis with Dr. Connie Leblanc, Dr. Joel Yaphe, Dr. David MacKinnon & Dr. Eric Letovsky. We then hear from Dr. Adam Cheng, Dr. Dennis Scolnick & Dr. Anna Jarvis in a pediatric expert panel about the newest on minor head injury, otitis media, mastoiditis and bronchiolitis. Dr. David Carr reviews one of the most important articles in 2011 regarding subarachnoid hemorrhage, and Dr. David MacKinnon gives us tonnes of clinical pearls when it comes to everyone's favourite subject, anorectal disorders.
