Background: The evaluation of acute ischemic stroke (AIS) patients should be performed expeditiously. Our stroke program maintained our Target: Stroke Honor Roll status in 2014, however, door-to-needle (DTN) time in Quarter 1 and 2 of 2015 showed no significant improvement and did not achieve DTN under 60 minutes in 75% of patients nor under 45 minutes in 50% of patients, despite in-servicing Emergency Department (ED)’s staff on program goals and order sets. The purpose of this project was to more effectively educate emergency stroke responders on clinical recognition and implementation of the organization’s stroke protocol order sets. Simulation as an experiential learning technique, promoting, applied thinking, delegation, and leadership skills. Evidence suggests simulation based training for adult learners promote their engagement and immediate application of learned material. Methods: Simulation: Stroke code responders, including 5 nurses per session, participated in the 90 minute scenario. Stroke protocol order sets were reviewed prior to the simulation of a right hemispheric syndrome. Participants elicited a focused history, National Institutes of Health Stroke Scale, relayed the findings to the neurologist, evaluate exclusion and inclusion criteria, and administered weight-based doses of tissue plasminogen activator (tPA). After a debrief, the participants repeated the simulation to reinforce new knowledge and skills. Descriptive statistics were used to compare mean DTN time before and after simulation training. Results: 153 ED nurses, 8 ED physicians, 6 neurologists, 4 pharmacists, 6 radiology technicians, and 10 phlebotomists participated. Pre -training Q1-Q2 2015 median DTN was 55 minutes, 65% </= 60 minutes, and 31% </= 45 minutes. Post-training data from Q1 2016 median DTN was 46 minutes, 75% </= 60 minutes, and 50% </= 45 minutes. Conclusion: Simulation based stroke responders training helped to decrease DTN time.

Abstract Objective To evaluate factors associated with anxiety and the effect of simulation-based training (SBT) on student anxiety, self-confidence and learning satisfaction in relation to pelvic and breast examination. Methods A longitudinal study was conducted with 4th year medical students at the Universidade José do Rosário Vellano. A 12-item, self-report questionnaire on student anxiety at performing gynecological examinations was applied before and after SBT, with answers being given on a Likert-type scale. After training, the self-confidence levels and satisfaction of the students related to the learning process were also evaluated. Results Eighty students with a mean age of 24.1 ± 4.2 years were included in the study. Of these, 62.5% were women. Pre-SBT evaluation showed that students were more anxious at performing a pelvic examination than a breast examination (2.4 ± 1.0 versus 1.7 ± 0.8, respectively; p < 0.001). The primary reason for anxiety regarding both pelvic and breast examination was fear of hurting the patient. SBT significantly reduced student anxiety (2.0 ± 0.8 versus 1.5 ± 0.5, respectively; p < 0.001). The satisfaction and self-confidence of the students were found to be high (6.8 ± 0.3 and 6.0 ± 0.9, respectively), with no difference between genders. Conclusion The use of SBT in teaching students to perform pelvic and breast examinations resulted in reduced anxiety and increased self-confidence in a group of medical students of both genders, with high levels of satisfaction in relation to the training.

BackgroundWhether to treat minor stroke with intravenous tissue plasminogen activator (t-PA) treatment or antiplatelet therapy is a dilemma. Our study aimed to explore whether intravenous t-PA treatment, dual antiplatelet therapy (DAPT) and aspirin have different efficacies on outcomes in patients with minor stroke.MethodsA post hoc analysis of patients with acute minor stroke treated with intravenous t-PA within 4.5 hours from a nationwide multicentric electronic medical record and patients with acute minor stroke treated with DAPT and aspirin from the Clopidogrel with Aspirin in Acute Minor Stroke or Transient Ischemic Attack Database. Minor stroke was defined by a score of 0–3 on the National Institutes of Health Stroke Scale at randomisation. Favourable functional outcome (defined as modified Rankin Scale (mRS) score of 0–1 or 0–2 at 3 months).ResultsCompared with those treated with intravenous t-PA, no significant association with 3-month favourable functional outcome (defined as mRS score of 0–1) was found neither in patients treated with aspirin (87.8% vs 89.4%; OR, 0.83; 95% CI, 0.46 to 1.50; p=0.53) nor those treated with DAPT (87.4% vs 89.4%; OR, 0.84; 95% CI, 0.46 to 1.52; p=0.56). Similar results were observed for the favourable functional outcome defined as mRS score of 0–2 at 3 months.ConclusionsIn our study, no significant advantage of intravenous t-PA over DAPT or aspirin was found. Due to insufficient sample size, our study is probably unable to draw such a conclusion that that intravenous t-PA was superior or non-superior to DAPT.

PurposeClinical trials have provided evidence that treating patients with acute ischaemic stroke (AIS) beyond 4.5 hours was feasible. Among them using MRI diffusion-weighted imaging/fluid attenuation inversion response (DWI/FLAIR) mismatch to guide intravenous tissue plasminogen activator (tPA) was successful. Our study explored the outcome and safety of using DWI/T2-weighted imaging (T2WI) mismatch to guide intravenous tPA therapy for patients with AIS between 4.5 hours and 12 hours of onset.MethodThis was a retrospective study. Records of 1462 AIS patients with the time of onset of <12 hours were reviewed. Those had MRI rapid sequence study and had hyperintense signal on DWI but normal T2WI and received intravenous tPA up to 12 hours of onset were included in the analysis. Their demographics, risk factors, post-tPA complications, National Institutes of Health Stroke Scale (NIHSS) scores and outcome were recorded and analyse. χ2 was used to compare the intergroup variables. SAS was used to perform statistical calculation. A p<0.05 was considered statistically significant.ResultsOf 1462 identified, 601 (41%) patients were entered into the final analysis. Among them, 327 (54%) had intravenous tPA within 4.5 hours of onset and 274 (46%) were treated between 4.5–12 hours. After intravenous tPA, 426 cases (71%) had >4 pints of improvement on NIHSS score within 24 hours. Postintravenous tPA, 32 (5.32%) cases had haemorrhagic transformation. 26 (4.33%) were asymptomatic ICH and 4 (0.67%) died. At 90 days, 523 (87%) achieved a modified Rankin scale of 0–2.ConclusionUsing MRI DWI/T2WI mismatch to identify patients with AIS for intravenous tPA between 4.5 hours and 12 hours was safe and effective. The outcome was similar to those used DWI/PWI or DWI/FLAIR mismatch as the screening tool. However, obtaining DWI/T2WI was faster and avoided the need of contrast material.

✓ Although complement activation is associated with tissue injury during inflammatory and ischemic states, complement activation in states of acute cerebral ischemia before and after administration of tissue plasminogen activator (TPA) has not yet been examined and is the focus of this investigation. Twenty-four New Zealand White rabbits weighing 3 to 3.5 kg were used for this study. Of these, 20 were subjected to intracranial autologous clot embolization via the internal carotid artery. Three hours postembolization, rabbits received an intravenous infusion of TPA (6.3 mg/kg, 20% bolus with the remainder infused over a 2-hour interval; 12 animals) or vehicle (eight animals). All animals were observed for a total of 7 or 8 hours postembolization. These two groups were compared to a cohort undergoing sham operation with subsequent TPA infusion (four animals). Plasma samples to quantify complement component C5 hemolytic activity (C5H5O) were obtained at the following time points: 30 minutes before and after clot embolization; 1 hour before and 1 hour after the initiation of therapy with TPA or vehicle and at the completion of the protocol; 7 to 8 hours after clot embolization. The C5 activation was not detected as the result of acute cerebral ischemia. However, animals receiving TPA with or without concomitant clot embolization exhibited C5 activation as assessed by a reduction in C5 hemolytic function, both 1 hour after initiation of TPA infusion (78.7 ± 10.3% and 77.5 ± 9.9% of baseline value, respectively; mean ± standard error of the mean [SEM]) and at the end of the protocol, 2 hours after the completion of the TPA infusion (72.5 ± 8.8% and 53.3 ± 8.1%, respectively; mean ± SEM, p < 0.05, each group). This study supports the conclusion that TPA, but not acute cerebral ischemia, may activate the complement cascade in this rabbit model of thromboembolic stroke.

"Background and aim: This study aimed to compare a serious game and lectures for the pretraining of medical students before learning about simulation-based management of cardiac arrest. Methods: Participants were 150 volunteer second-year medical students between April and June 2018 randomly assigned to CPR training using either lectures (n = 75) or a serious game (n = 75). Each participant was evaluated on a scenario of cardiac arrest before and after exposure to the learning methods. The primary outcome measures were the median total training time needed for the student to reach the minimum passing score. This same outcome was also assessed three months later. Results: The median training time necessary for students to reach the minimum passing score was similar between the two groups (p=0,45). Achieving an appropriate degree of chest compression was the most difficult requirement to fulfill for students in both groups. Singing the refrain of the song ""staying alive"" significantly increased the number of compressions with the correct rate. Three months later, the median training time decreased significantly in both groups. However, students have remained interested in the serious game for a longer time showing a preference for using this method. Conclusions: The serious game was not superior to lectures to pretraining medical students in the management of a cardiac arrest."

BackgroundComputerised provider order entry (CPOE) is rapidly becoming the mainstay in clinical care and has the potential to improve provider efficiency and accuracy. However, this hinges on careful planning and implementation. Poorly planned CPOE order sets can lead to undetected errors and waste. In our emergency department (ED), lactate dehydrogenase (LDH) was bundled into various blood work panels but had little clinical value.ObjectivesThis quality improvement initiative aimed to reduce unnecessary LDH testing in the ED.MethodsA group of ED physicians reviewed CPOE blood work panels and uncoupled LDH in conditions where it was deemed not to provide any clinically useful information. We measured the daily number of LDH tests performed before and after its removal. We tracked the frequency of other serum tests as controls. We also analysed the number of add-on LDH (ie, to add LDH to samples already sent to the lab) as a balancing measure, since this can disrupt work flow and delay care.ResultsThrough this intervention, we reduced the number of LDH tests performed by 69%, from an average of 75.1 tests per day to 23.2 (P<0.0005). The baseline controls did not differ after the intervention (eg, a complete blood count was performed 197.7 and 196.1 times per day preintervention and postintervention, respectively (P=0.7663)). There was less than one add-on LDH per day on average.ConclusionsCPOE care templates can be powerful in shaping behaviours and reducing variability. However, close oversight of these panels is necessary to prevent errors and waste.

Background: Endovascular therapy and intravenous thrombolysis with recombinant tissue plasminogen activator are the 2 most recommended treatments for acute ischemic stroke (AIS). Glycoprotein (GP) IIb-IIIa inhibitors are short-acting selective reversible antiplatelet agents that emerged as promising therapeutic agents for AIS about 10 years ago. Given the unclear safety profile and application coverage of GP inhibitors, we conducted this meta-analysis to explore the same. Methods: We used GP IIb-IIIa inhibitors, intracranial hemorrhage, and mortality as the key words on Medline, Web of Science, and the Embase databases. Randomized controlled trials, prospective literatures, and retrospective studies in English published between 1990 and 2020 were screened. The outcomes were relative risk (RR) of death and 90-day intracerebral hemorrhage (ICH). We pooled the results in 2 categories and conducted a subgroup analysis stratified by different drugs. The choice of the effects model depended on the value of I 2. Results: In all, 3700 patients from 20 studies were included. No GP IIb-IIIa inhibitors were found to have a remarkable influence on the ICH rate. The RR values of symptomatic ICH for abciximab and eptifibatide were 4.26 (1.89, 9.59) and 0.17 (0.04, 0.69), respectively. Both tirofiban and abciximab could decrease the mortality rate within 90 days. Age > 70 years, National Institutes of Health Stroke Scale > 15, and overall dose > 10 mg are risk factors for ICH events with tirofiban usage. Thrombectomy combined with tirofiban was safe for arterial reocclusion prevention. Conclusions: In stroke-related treatment, administration of GP IIb-IIIa inhibitors could be safe, but care should be taken regarding drug species and doses. Abciximab can increase the risk of symptomatic intracranial hemorrhage. Tirofiban and eptifibatide can be considered safe in low doses. Suitable patients should be selected using strict criteria.

Purpose Acute radiologic emergencies, primarily severe contrast reactions, are rare but life-threatening events. Given a generalized paucity of formalized or mandated training, studies have shown that radiologists and trainees perform poorly when acutely managing such events. Moreover, skill base, knowledge, and comfort levels precipitously decline over time given the infrequent occurrence of these events during one's daily practice. The primary aim of this study was to assess radiologists' preparedness for managing acute radiologic emergencies and to determine the efficacy of a high-fidelity simulation based training model in an effort to provide a rationale for similar programs to be implemented on a provincial or national level. Methods This was a prospective, observational study of radiology residents and attending radiologists throughout the province who were recruited to attend a full-day simulation-based course presenting various cases of acute radiologic emergencies. Participant demographics were collected at the time of commencement of the workshop. Course materials were disseminated 4 weeks prior to the workshop, and a 17-question knowledge quiz was administered before and after the workshop. Likert-type questionnaires were also distributed to survey comfort levels and equipment familiarity. The knowledge quiz and questionnaire were redistributed at 3- and 6-month intervals for acquisition of follow-up data. Results A total of 14 attending radiologists and 7 residents attended the workshop, with all participants completing the preworkshop questionnaire and 90.5% (19 of 21) completing the post-workshop questionnaire. Participants' principle locations of practice were as follows: academic institutions (50%), community hospitals (36.9%), and private clinics (13.1%). A significant increase in knowledge was demonstrated, with average scores of 10 out of 17 (59%) and 14.5 out of 17 (85%) ( P < .001) before and after the workshop, respectively. A significant increase in participants' comfort levels in recognizing acute anaphylactic reactions (3.5; 4.7, P < .001), commencing initial management for acute radiologic emergencies (3.3; 5.0, P < .001), and administering the correct dose for anaphylactic reactions (2.5; 4.8, P < .001) was also demonstrated. Moreover, participants became increasingly familiar with the contents and equipment found within contrast reaction kits (2.8; 3.8, P < .01). Repeat evaluations at 3 and 6 months found an average knowledge test score of 13.8 out of 17 (81%) and 10.8 out of 17 (64%), respectively. Comfort levels were also reassessed in recognizing acute anaphylactic reactions (4.5; 4.1), commencing initial management (4.0; 3.9) and administering the correct dose of medication (4.0; 3.7) at 3- and 6-month intervals. Conclusions Acute radiologic emergencies are rare but life-threatening events that require rapid diagnosis and treatment to mitigate associated morbidity and mortality. Simulation-based workshops are a highly efficacious training model to increase knowledge, comfort levels, and equipment familiarity for radiologists and trainees alike; however, retraining at regular intervals is required.
