Comparison of the age-adjusted and clinical probability-adjusted D-dimer to exclude pulmonary embolism in the ED.

BACKGROUND: Diagnosing pulmonary embolism (PE) in the emergency department (ED) can be challenging because its signs and symptoms are non-specific. OBJECTIVE: We compared the efficacy and safety of using age-adjusted D-dimer interpretation, clinical probability-adjusted D-dimer interpretation and standard D-dimer approach to exclude PE in ED patients. DESIGN/METHODS: We performed a health records review at two emergency departments over a two-year period. We reviewed all cases where patients had a D-dimer ordered to test for PE or underwent CT or VQ scanning for PE. PE was considered to be present during the emergency department visit if PE was diagnosed on CT or VQ (subsegmental level or above), or if the patient was subsequently found to have PE or deep vein thrombosis during the next 30 days. We applied the three D-dimer approaches to the low and moderate probability patients. The primary outcome was exclusion of PE with each rule. Secondary objective was to estimate the negative predictive value (NPV) for each rule. RESULTS: 1163 emergency patients were tested for PE and 1075 patients were eligible for inclusion in our analysis. PE was excluded in 70.4% (95% CI 67.6-73.0%), 80.3% (95% CI 77.9-82.6%) and 68.9%; (95% CI 65.7-71.3%) with the age-adjusted, clinical probability-adjusted and standard D-dimer approach. The NPVs were 99.7% (95% CI 99.0-99.9%), 99.1% (95% CI 98.3-99.5%) and 100% (95% CI 99.4-100.0%) respectively. CONCLUSION: The clinical probability-adjusted rule appears to exclude PE in a greater proportion of patients, with a very small reduction in the negative predictive value.

BET 2: Treating migraines with diclofenac instead of a triptan.

A shortcut review was carried out to establish whether diclofenac is better than a triptan in treating migraine. 32 papers were found of which only 1 addressed this question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of this paper are tabulated. It is concluded that there is insufficient evidence that either treatment is superior to the other for migraine therapy.

From Innovation to Intrapreneurship: Fostering academic success via the GridlockED project and innovation fund.

Background: Funding for educational innovations is increasingly scarce in academic medicine. While there is some funding for medical education research, this is often for discovery or application work, and there are few avenues for those with a heavy innovation focus to fund early work. Objective of the Innovation: The objective was to develop an intrapreneurial unit focused on medical education projects and scholarship. Development Process and Implementation: The GridlockED and TriagED games are educational or serious games that seek to teach health care learners about emergency medicine processes. Both games were cocreated with learners and brought to market in the past 3 years. All of the proceeds from the sales of these games have been accrued over time to create a new innovation fund. This fund seeks to support trainees and early career educators in their medical education projects. Outcomes: Sales for GridlockED began in March 2018 and the TriagED began in November 2019. In the first year, sales for GridlockED yielded a total of $9,534. After 18 months of sales, the fund has accrued a total of $14,530. The fund has helped finance the development of new games. Additionally, the fund awarded two internal $500 Kickstarter grants to assist with evaluating and improving two local education projects. The GridlockED and TriagED games have also spurred multiple academic opportunities for junior educators interested in this domain: five workshops, eight conference abstracts, two peer-reviewed papers, and two research protocols are being developed. Conclusions: The GridlockED and TriagED games represent a new academically oriented, intrapreneurial approach to medical education work.

Creating GridlockED: A Serious Game for Teaching About Multipatient Environments.

PROBLEM: As patient volumes increase, it is becoming increasingly important to find novel ways to teach junior medical learners about the intricacies of managing multiple patients simultaneously and about working in a resource-limited environment. APPROACH: Serious games (i.e., games not intended purely for fun) are a teaching modality that have been gaining momentum as teaching tools in medical education. From May 2016 to August 2017, the authors designed and tested a serious game, called GridlockED, to provide a focused educational experience for medical trainees to learn about multipatient care and patient flow. The game allows as many as six people to play it at once. Gameplay relies on the players working collaboratively (as simulated members of a medical team) to triage, treat, and disposition "patients" in a manner that simulates true emergency department operations. After researching serious games, the authors developed the game through an iterative design process. Next, the game underwent preliminary peer review by experienced gamers and practicing clinicians, whose feedback the authors used to adjust the game. Attending physicians, nurses, and residents have tested GridlockED for usability, fidelity, acceptability, and applicability. OUTCOMES: On the basis of initial testing, clinicians suggest that this game will be useful and has fidelity for teaching patient-flow concepts. NEXT STEPS: Further play testing will be needed to fully examine learning opportunities for various populations of trainees and for various media. GridlockED may also serve as a model for developing other games to teach about processes in other environments or specialties.

STI initiative: Improving testing for sexually transmitted infections in women.

Canadian urgent care and walk-in medical clinics provide health care for a population that may be poorly covered by traditional health care structures. Despite evidence suggesting that women with urinary complaints experience a high incidence of sexually transmitted infections (STIs), this population may be under-tested in this particular setting. The aim of this quality improvement initiative was to increase STI testing in women presenting with GU complaints. Implementation of an opt-out method of STI testing for women ages 16 and older was introduced at three walk-in clinics. Women presenting with GU complaints were given the opportunity to provide samples for both conventional urine culture and nucleic acid amplification testing (NAAT) for non-viral STIs. Patients received treatment according to standard of care and public health was notified as per local regulations. Testing rate and STI incidence was tracked via clinic electronic medical records (EMRs). Overall results were tracked using run charts and compared to historical data for the year prior to the start of the project. Over a 1 year period prior to this intervention, only 65 STI tests were performed in over 1100 GU complaints (5.5%). Six STIs were identified during this time. During the 36-week project period, testing increased to 45% of the patient population (320/707). The STI detected incidence increased from 0.51% to 1.4% in all women, and from 0.84% to 3.4% in women aged 16-29 years. An opt-out method was an effective intervention for increasing STI testing within the walk-in clinic setting. With optimisation, significant increases in testing rates can be obtained without substantially increasing clinic workload and at no economic cost to the clinic. As expected, detected incidence rates of STIs were higher than the recognised population prevalence.
