ABSTRACT
OBJECTIVES: After introducing a team simulation training programme at our hospital, we saw a reduction in door-to-needle times (DNT) for stroke thrombolysis but persisting variability prompting further investigation. Our objective is to examine this gap through assessing: (1) whether there is an association between DNT and the clinical experience of neurology registrars and (2) whether experience influences the benefits from attending simulation. DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: Patients treated with intravenous thrombolysis between January 2016 and 2020 at a Norwegian stroke centre. PRIMARY AND SECONDARY OUTCOME MEASURES: Using DNT and prior intravenous thrombolysis administrations (case-based definition of clinical experience) as continuous variables, a mixed effects linear regression model was performed to examine the association between clinical experience, DNT and simulation attendance. For dichotomised analyses, neurology registrars with 15 or more prior treatments were defined as experienced. RESULTS: A total of 532 patients treated by 36 neurology registrars from January 2016 to 2020 were included. There was a linear association between clinical experience and DNT (test for non-linearity p=0.479). Each prior intravenous thrombolysis administration was associated with a significant 1.1% decrease in DNT in the adjusted analysis (ΔDNT -1.1%; 95% CI, -2.2% to -0.0%; p=0.048). The interaction between effects of clinical experience and simulation on DNT was not statistically significant (p=0.150). In the dichotomised analysis, experienced registrars had similar gains from attending simulation sessions (mean DNT from 18.5 min to 13.5 min) compared with less experienced registrars (mean DNT from 22.4 min to 17.4 min). CONCLUSIONS: Less experienced registrars had longer DNT in stroke thrombolysis. Attending team simulation training was associated with similar improvements for experienced and inexperienced neurology registrars. We suggest a focus on high-quality onboarding programmes to close the experience-related quality gap. Our findings suggest that both inexperienced and experienced neurology registrars might benefit from team simulation training for stroke thrombolysis.

BACKGROUND: In 2019, the emergency medical services (EMS) covering the western Norway Regional Health Authority area implemented its version of the prehospital clinical criteria G-FAST (Gaze deviation, Facial palsy, Arm weakness, Visual loss, Speech disturbance) to detect acute ischaemic stroke (AIS) with large vessel occlusion (LVO). For patients with gaze deviation and at least one other G-FAST symptom, a primary stroke centre (PSC) may be bypassed and the patient taken directly to a comprehensive stroke centre (CSC) for rapid endovascular treatment (EVT) evaluation. The study aim was to investigate the efficacy of the G-FAST criteria for LVO patient selection and direct transfer to a CSC. METHODS: This retrospective study included patients with code-red emergency medical communication centre (EMCC) stroke suspicion ambulance dispatch between August to December 2020. Stroke suspicion was defined as having at least one G-FAST symptom at EMS arrival. We obtained patient data from dispatches from EMCCs, EMS records and local EVT registries. Clinical features, CT images, and reperfusion treatment were recorded. The test characteristics for gaze deviation plus one other G-FAST symptom in detecting LVO were determined. RESULTS: Among 643 patients, 59 were diagnosed with LVO at hospital arrival. In this group, seven fulfilled the G-FAST criteria for direct transport to a CSC at EMS arrival on scene, resulting in a sensitivity of 12% (95% CI 5% to 23%). The specificity was 99.66% (95% CI 98.77% to 99.96%), the positive predictive value 78%, and the negative predictive value 92%. EVT was performed in 64% (38/59) of LVO cases. Median time from PSC arrival to start of EVT at a CSC was 163 min. CONCLUSION: The use of local G-FAST prehospital criteria by EMS personnel to identify patients with AIS with LVO is not suitable for selection of patients with LVO for direct transfer to a CSC.

Background: Every year, large numbers of individuals are present or provide first aid in situations involving out-of-hospital cardiac arrest, injuries, or suicides. Little is known about the impact of providing first aid or witnessing a first aid situation, but research indicates that many first aid providers (FAP) experience persistent psychological difficulties. Here we aimed to assess the level of psychological impact of being a FAP. Methods: In this retrospective study, FAP attending follow-up were asked to complete the International Trauma Questionnaire (ITQ), which is a self-report diagnostic measure of post-traumatic stress disorder (PTSD) and complex post-traumatic stress disorder (CPTSD). We recorded endorsement of a symptom or functional impairment (score ≥ 2/4 on at least one of 18 items). Results: Of the 102 FAP in this study, 86 (84%) showed endorsement of a symptom or functional impairment. Common symptoms/functional impairments included being super-alert, watchful, or on guard; having powerful mental images; avoiding internal reminders or memories; and being affected in important parts of one's life. One-third had affected ability to work. Of the FAPs who attended follow-up more than one month after the incident (n = 32), 19% met the criteria for PTSD or CPTSD. Conclusions: The majority of FAPs have endorsement of a symptom or functional impairment. Some FAPs fulfil the criteria of PTSD. We suggest that follow-up should be offered by the EMS to all FAPs involved in incidents with an unconscious patient.
ABSTRACT
OBJECTIVES: The Norwegian Cardiac Arrest Registry (NorCAR) was established in 2013 when cardiac arrest became a mandatory reportable condition. The aim of this cohort study is to describe how the world's first mandatory, population-based cardiac arrest registry evolved during its first 6 years. SETTING: Norway has a total population of 5.3 million inhabitants with a population density that varies considerably. All residents are assigned a unique identifier number, giving nationally approved registries access to information about all births and deaths in the country. Data in the registry are entered by data processors; public employees with close links to the emergency medical services. All data processors undergo a standardised training and meet for yearly retraining and updates. PARTICIPANTS: All events of cardiac arrest where bystanders or healthcare professionals have started cardiopulmonary resuscitation or performed defibrillation are included into the NorCAR. PRIMARY AND SECONDARY OUTCOME MEASURES: Since the establishment of the registry, the number of reporting health trusts, the number of reported events and the corresponding population at risk were followed year by year. Outcome is measured as changes in inclusion rate, incidence per 100 000 inhabitants and survival to 30 days after cardiac arrest. RESULTS: In total, 14 849 cases were registered over 6 years, between 2013 and 2018. The number of health trusts reporting rose steadily from 2013. Within 3 years, all trusts reported to the registry with an increasing number of events reported; going from 1101 to 3400 per year. The prevalence of bystander cardiopulmonary resuscitation increased slightly, but the population incidence of survival did not change. CONCLUSION: Declaring cardiac arrest as a reportable condition and close follow-up of all reporting areas is essential when building a national registry.

AIM OF THE STUDY: Out-of-hospital cardiac arrest (OHCA) is a major cause of death in the western world. We wanted to study changes in survival over time and factors linked to this in a region which have already reported high survival rates. METHODS: We used a prospectively collected Utstein template database to identify all resuscitation attempts in adult patients with OHCA of presumed cardiac origin. We included 846 resuscitation attempts and compared survival to discharge with good outcome in two time periods (2001-2005 vs. 2006-2008). RESULTS: We found no significant differences between the two time periods for mean age (71 and 70 years (p=0.309)), sex distribution (males 70% and 71% (p=0.708)), location of the OHCA (home 64% and 63% (p=0.732)), proportion of shockable rhythms (44% and 47% (p=0.261)) and rate of return of spontaneous circulation (38% and 43% (p=0.136)), respectively. Bystander cardiopulmonary resuscitation (CPR), however, increased significantly from 60% to 73% (p<0.0001), as did the overall rate of survival to discharge from 18% to 25% (p=0.018). In patients with a shockable first rhythm, rate of survival to discharge increased significantly from 37% to 48% (p=0.036). In witnessed arrest with shockable rhythm survival to discharge increased from 37% to 52% (p=0.0105). CONCLUSION: Overall, good outcome is now achievable in every fourth resuscitation attempt and in every second resuscitation attempt when patients have a shockable rhythm. The reason for the better outcomes is most likely multi-factorial and linked to improvements in the local chain of survival.
