Impact of a financial incentive on the completion of educational metrics.

Int J Emerg Med 2020 Dec 1;13(1):60. Epub 2020 Dec 1.

Division of Emergency Medicine, University of Utah, Salt Lake City, UT, USA.

Background: The Accreditation Council for Graduate Medical Education (ACGME) requires all emergency medicine (EM) training programs to evaluate resident performance and also requires core faculty to attend didactic conference. Assuring faculty participation in these activities can be challenging. Previously, our institution did not have a formal tracking program nor financial incentive for participation in these activities. In 2017, we initiated an educational dashboard which tracked and published all full-time university faculty conference attendance and participation in resident evaluations and other educational activities.

Objectives: We sought to determine if the implementation of a financially-incentivized educational dashboard would lead to an increase in faculty conference attendance and the number of completed resident evaluations.

Methods: We conducted a pre- and post-intervention observational study at our EM residency training program between July 2017 and July 2019. Participants were 17 full-time EM attendings at one training site. We compared the number of completed online resident evaluations (MedHub) and number of conference days attended (call-in verification) before and after the introduction of our financial incentive in June 2018. The incentive required 100% completion of resident evaluations and at least 25% attendance at eligible didactic conference days. We calculated pre- and post-intervention averages, and comparisons were made using a chi-square test.

Results: Prior to implementation of the intervention, the 90-day resident evaluation completion rate was 71.8%. This increased to 100% after implementation (p < 0.001). Conference attendance prior to implementation was 43.8%, which remained unchanged at 41.3% after implementation of the financial incentive (p = 0.920).

Conclusions: Attaching a financial incentive to a tracked educational dashboard increased faculty participation in resident evaluations but did not change conference attendance. This difference likely reflects the minimum thresholds required to obtain the financial incentive.

Complications of percutaneous nephrostomy in a district general hospital.

Turk J Urol 2018 Nov;44(6):478-483

Department of Urology, Countess of Chester Hospital, Chester, UK.

Objective: Percutaneous nephrostomy (PCN) is one of the commonest procedures performed. There are currently no European recommendations on the accepted rate of complications. The aim of the present study is to report the complication rate of PCN with the specific emphasis on sepsis and septic shock, the causative organisms, sensitivities to antibiotics, and associated risk factors.

Material And Methods: Retrospectively collected data on patients undergoing acute or elective PCN at the Department of Radiology, Countess of Chester Hospital (COCH), in the UK between January 2014 and December 2016 were analyzed after the study was approved by Local Audit Department at COCH.

Results: A total of 66 patients underwent 90 acute or elective PCNs. Three patients developed major post-PCN complication (two patients developed septic shock and the third suffered a hemorrhagic episode requiring blood transfusion). Nephrostomy tube complications (blockage, leaking, fracturing and kinking of the catheter) occurred in 4 patients. Complications were more common when the PCN was performed out of working hours (71.4% [10/14], and 17.3% [9/52] for PCNs performed within, and out of working hours, respectively: p<0.001). The age of the patients did not seem to correlate with the development of complications (p<0.001). Of all 25 patients, in whom septicemia was diagnosed prior to PCN tube insertion, 12 developed septic shock and 13 had signs of sepsis for longer than 24 h. Fifteen patients had positive urine cultures. The most common organism isolated was Escherichia coli. Blood culture isolates included: Escherichia coli, Eggerthella lenta, Enterococcus, Proteus mirabilis, Pseudomonas aeruginosa and Streptococcus pneumonia.

Conclusion: Our complication rates were within United States proposed target ranges. Our data may help to serve as a baseline for outcome targets in the European centres.

Is magnetic resonance imaging helpful in detecting significant prostate cancer in patients with haematospermia, normal prostate specific antigen level and digital rectal examination. A single institution, observational, and retrospective study in a United Kingdom hospital.

Cent European J Urol 2018 22;71(1):26-30. Epub 2017 Jan 22.

Countess of Chester Hospital, Department of Urology, Chester, United Kingdom.

Introduction: Haematospermia is an uncommon clinical condition that may be associated with prostate cancer. The optimal investigation of haematospermia is unknown. The aim of this study was to investigate haematospermia as a presenting symptom of significant pathology and to assess the diagnostic value of magnetic resonance imaging (MRI).

Material And Methods: Patient and treatment parameters were collected from a practice cohort of men referred to a urology center presenting with haematospermia. We used a multivariate logistic regression model to test the independent significance of MRI in detecting prostate cancer (PCa) after adjusting for other known predictors of PCa detection.

Results: A total of 125 men (median age 58 years) were evaluated between 2012-2015. In the univariate and multivariate logistic regression model MRI was a significant predictor of PCa diagnosis after adjusting for age, prostate specific antigen (PSA) and digital rectal examination (DRE) results (Odds Ratio (OR) 14.15, p = 0.001). Of 107 patients who underwent MRI prostate imaging, 31 (28.9%) had reports suspicious of PCa. In 26 patients, other benign conditions were detected on MRI. PCa was detected in 12 (25.5%) of the 47 men (median age 61 years; range 43 to 85) who underwent prostate biopsies. Eight (17%) of these patients had Gleason ≥7 grade cancer. The persistence of haematospermia was not an independent predictor of cancer diagnosis (OR 0.20, p = 0.15).

Conclusions: PCa is not commonly associated with haematospermia. MRI seems to be improving detection rate of a significant PCa, particularly in patients presenting with haematospermia and normal PSA levels and DRE examination. Duration of haematospermia does not predict the presence of PCa.

Impact thromboelastometry (ITEM) for point-of-injury detection of trauma-induced coagulopathy: a pilot study.

Trauma Surg Acute Care Open 2017 2;2(1):e000049. Epub 2017 Mar 2.

Division of Emergency Medicine, Department of Surgery, University of Utah, Salt Lake City, Utah, USA.

Background: Acute coagulopathy of trauma is associated with high mortality and extensive use of blood products. Hemostatic resuscitation, the early administration of blood products with higher ratios of procoagulant components, may improve trauma outcomes in select cases, but can also worsen outcome if inappropriately used. Evolving approaches to hemostatic resuscitation utilize viscoelastic tests to provide a more rational basis for choosing blood component therapy regimens, but these tests are logistically rigorous. We hypothesized that coagulopathy could be detected by the failure of blood clots to remain intact when subjected to a predefined impact force.

Methods: We aim to develop a point-of-injury test for coagulopathy. We created coagulopathic blood using an ex vivo normal saline (NS) dilution model and allowed blood of varying dilutions to clot, then examined the behavior of the clotted blood when subjected to a uniform gravitationally induced sheer force.

Results: Clots created from coagulopatic blood (diluted to ≤50% with NS) failed under gravitational challenge at a significantly higher rate than non-coagulopathic blood dilutions.

Discussion: Impact thromboelastometry (ITEM) represents a simple, logistically lean method for detecting dilutional coagulopathy that may facilitate detection of trauma-induced coagulopathy. ITEM may thus function as a point-of-injury or point-of-care screening test for the presence of coagulopathy.

Level Of Evidence: Diagnostic studies, Level IV.

Mitigate, adapt, or suffer: Peak oil's new disaster paradigm.

Gerard S Doyle

Am J Disaster Med 2010 Sep-Oct;5(5):315-9

Division of Emergency Medicine, University of Utah School of Medicine, Salt Lake City, Utah, USA.

Objectives: To address the impacts of peak oil (PO) on human health and to propose new public health preparedness models and measures mandated by these impacts.

Design: Review of relevant literature. Articles were obtained by searching the PubMed database (including manual searches using "related citations" tool) plus Google and Google Scholar search engines using terms such as "peak oil," "energy scarcity," "human health," "public health," and "preparedness."

Results: Forty-six journal articles were reviewed.

Conclusions: The projections about PO are concerning, as illustrated by minor PO events in the recent past. There are many opportunities for devising beneficial solutions within healthcare to mitigate the effects of PO. It is essential for disaster medicine professionals to become aware of PO and to advocate for change in clinical practice with patients as well as policy leaders. If we fail to mitigate the effects of PO on healthcare, we will be left with the less pleasant options of adapting to PO or suffering its effects.

Amyand hernia: a case of an unusual inguinal herniace.

Am J Emerg Med 2008 Jun;26(5):637.e5-6

Division of Emergency Medicine, University of Wisconsin School of Medicine and Public Health, Madison, WI 53792, USA.

Amyand hernia, named for the first person to describe an inguinal hernia containing the vermiform appendix, is an uncommon variant of an inguinal hernia. Presence of the appendix in the sac complicates the management of inguinal hernias. The appendix may be more prone to rupture when contained within a hernia sac, and herniation of an inflamed appendix into the scrotum can mimic an acute scrotum. A 50-year-old man presented with right lower quadrant abdominal pain associated with chills and anorexia. Physical examination revealed right lower quadrant tenderness and a right inguinal mass without associated skin changes. Laboratories were normal. A plain abdominal computed tomography scan for acute appendicitis showed an indirect right inguinal hernia with the appendix contained within the sac, which was incarcerated. Surgical consultation was obtained. The patient taken to the operating room, and his appendix was removed. The hernia was coincidentally repaired, and the patient was discharged soon thereafter. In cases suggestive of acute appendicitis complicating an inguinal hernia, the diagnosis of this unusual variant must be considered.

Tourniquets: a review of current use with proposals for expanded prehospital use.

Prehosp Emerg Care 2008 Apr-Jun;12(2):241-56

Division of Emergency Medicine, Department of Medicine, University of Utah, Salt Lake City, Utah, USA.

The use of arterial tourniquets in prehospital emergency care has been fraught with controversy and superstition for many years despite the potential utility of these tools. This review examines this controversy in the context of the history of the tourniquet as well as its recent use in surgery and modern battlefield casualty care. Safe prehospital tourniquet use is widespread in the military and is based on sound physiologic data and clinical experience from the surgical use of tourniquets. The physiologic, pathophysiologic, and clinical underpinnings of safe tourniquet use are reviewed here, along with a discussion of alternatives to tourniquets. Prehospital settings in which tourniquets are useful include tactical emergency medical services (EMS) and other law enforcement environments as well as disaster and mass casualty incidents. Beyond this, we present arguments for tourniquet use in more routine EMS settings, in which it may be beneficial but has heretofore been considered inappropriate. Protocols that foster safe, effective prehospital tourniquet use in these settings are then presented. Finally, we discuss future directions in which tourniquet research and other initiatives will further enhance the safe, rational use of this potentially life-saving tool.
