COSCA (Core Outcome Set for Cardiac Arrest) in Adults : An Advisory Statement From the International Liaison Committee on Resuscitation

Cardiac arrest effectiveness trials have traditionally reported outcomes that focus on survival. A lack of consistency in outcome reporting between trials limits the opportunities to pool results for meta-analysis. The COSCA initiative (Core Outcome Set for Cardiac Arrest), a partnership between patients, their partners, clinicians, research scientists, and the International Liaison Committee on Resuscitation, sought to develop a consensus core outcome set for cardiac arrest for effectiveness trials. Core outcome sets are primarily intended for large, randomized clinical effectiveness trials (sometimes referred to as pragmatic trials or phase III/IV trials) rather than for pilot or efficacy studies. A systematic review of the literature combined with qualitative interviews among cardiac arrest survivors was used to generate a list of potential outcome domains. This list was prioritized through a Delphi process, which involved clinicians, patients, and their relatives/partners. An international advisory panel narrowed these down to 3 core domains by debate that led to consensus. The writing group refined recommendations for when these outcomes should be measured and further characterized relevant measurement tools. Consensus emerged that a core outcome set for reporting on effectiveness studies of cardiac arrest (COSCA) in adults should include survival, neurological function, and health-related quality of life. This should be reported as survival status and modified Rankin scale score at hospital discharge, at 30 days, or both. Health-related quality of life should be measured with >= 1 tools from Health Utilities Index version 3, Short-Form 36-Item Health Survey, and EuroQol 5D-5L at 90 days and at periodic intervals up to 1 year after cardiac arrest, if resources allow.Peer reviewe

Prehospital nursing students' experiences of patient safety culture in emergency medical services-A qualitative study

Aims and Objectives To describe prehospital nursing students' experiences of patient safety culture in emergency medical services during their internship. Background Patient safety culture in the emergency medical services is a complex phenomenon including more than organisational policies and practices and professionals' technical skills. Design The descriptive qualitative approach used the Sharing Learning from Practice to improve Patient Safety Learning Event Recording Tool, which includes both open-ended and structured questions. Methods Purposeful sampling was used, and data were collected from graduating prehospital nursing students (n = 17) from three Finnish Universities of Applied Sciences. Open-ended questions were reviewed using thematic analysis, and frequencies and percentages were derived from structured questions. COREQ guidelines were used to guide this study. Results Four themes were identified during the thematic analysis: environmental and other unexpected factors in emergency medical services, working practices and professionalism in emergency medical services, teamwork in emergency medical services and feelings related to patient safety events in emergency medical services. Patient safety events described by students were seldom reported in the healthcare system or patient files. According to the students, such events were most likely related to communication, checking/verification and/or teamwork. Conclusions This study shows that prehospital nursing students can produce important information about patient safety events and the reasons that contributed to those events. Therefore, emergency medical services organisations and managers should use students' observations to develop a patient safety culture in emergency medical services. Relevance to clinical practice Understanding how prehospital nursing students have experienced patient safety culture during their internships on ambulances can support educational institutions, together with emergency medical services organisations and managers, to improve policies for students to express patient safety concerns as well as patient safety successes.Peer reviewe

Serious conditions among patients with non-specific chief complaints in the pre-hospital setting : a retrospective cohort study

Background Emergency Medical Services (EMS) are faced daily with patients presenting with a non-specific chief complaints (NSC); i.e. decreased general condition, general malaise, sense of illness, or just being unable to cope with usual daily activities. Patients presenting with NSCs often have normal vital signs. It has previously been established that however, NSCs may have a serious underlying condition that has yet to be identified. The primary outcome of this study was to determine the prevalence of serious conditions in patients presenting with NSCs to the EMS. Method A retrospective cohort study of patients >= 18 years of age who were reported as presenting with chief complaints compatible with NSCs to the EMS in Stockholm Region and transported to an emergency department between January 1st, 2013 and December 31st, 2013. Patients were identified via the EMS electronic health care record and followed via records from the National Patient Registry and Causes of Death Registry at Sweden's National Board for Health and Welfare. The definition of serious condition was defined by expert consensus. Descriptive statistics as well as regression analyses were used. Results A total of 3780 patients were included, with a median age of 77 years. A serious condition was present in 35.3% of the patients. The in-hospital mortality rate for the group with serious conditions was 10.1% (OR 6.8, CI 95%, 4.1-11.3), and the 30-day mortality rate was 20.2% (OR 3.1, CI 95%, 2.3-4.0). In the group with no serious conditions the rates were 1.0 and 4.2%, respectively. The total hospitalization rate was 67.6%. The presence of serious conditions as well as increased mortality rates were associated with Rapid Emergency Triage and Treatment system (RETTS) as well as National Early Warning Score (NEWS) irrespective of triage score. Conclusion More than one-third of the patients presenting with NSCs to EMS had a serious underlying condition which was associated with increased mortality and hospitalization rates.Peer reviewe

A comparison of two emergency medical dispatch protocols with respect to accuracy

Background: Emergency medical dispatching should be as accurate as possible in order to ensure patient safety and optimize the use of ambulance resources. This study aimed to compare the accuracy, measured as priority level, between two Swedish dispatch protocols - the three-graded priority protocol Medical Index and a newly developed prototype, the four-graded priority protocol, RETTS-A. Methods: A simulation study was carried out at the Emergency Medical Communication Centre (EMCC) in Stockholm, Sweden, between October and March 2016. Fifty-three voluntary telecommunicators working at SOS Alarm were recruited nationally. Each telecommunicator handled 26 emergency medical calls, simulated by experienced standard patients. Manuscripts for the scenarios were based on recorded real-life calls, representing the six most common complaints. A cross-over design with 13 + 13 calls was used. Priority level and medical condition for each scenario was set through expert consensus and used as gold standard in the study. Results: A total of 1293 calls were included in the analysis. For priority level, n = 349 (54.0%) of the calls were assessed correctly with Medical Index and n = 309 (48.0%) with RETTS-A (p = 0.012). Sensitivity for the highest priority level was 82.6% (95% confidence interval: 76.6-87.3%) in the Medical Index and 54.0% (44.3-63.4%) in RETTS-A. Overtriage was 37.9% (34.2-41.7%) in the Medical Index and 28.6% (25.2-32.2%) in RETTS-A. The corresponding proportion of undertriage was 6.3% (4.7-8.5%) and 23.4% (20.3-26.9%) respectively. Conclusion: In this simulation study we demonstrate that Medical Index had a higher accuracy for priority level and less undertriage than the new prototype RETTS-A. The overall accuracy of both protocols is to be considered as low. Overtriage challenges resource utilization while undertriage threatens patient safety. The results suggest that in order to improve patient safety both protocols need revisions in order to guarantee safe emergency medical dispatching.Peer reviewe

Percutaneous coronary intervention still not accessible for many South Africans

Introduction: The incidence of myocardial infarction is rising in Sub-Saharan Africa. In order to reduce mortality, timely reperfusion by percutaneous coronary intervention (PCI) or thrombolysis followed by PCI is required. South Africa has historically been characterised by inequities in healthcare access based on geographic and socioeconomic status. We aimed to determine the coverage of PCI-facilities in South Africa and relate this to access based on population and socio-economic status. Methods: This cross-sectional study obtained data from literature, directories, organisational databases and correspondence with Departments of Health and hospital groups. Data was analysed descriptively while Spearman's Rho sought correlations between PCI-facility resources, population, poverty and medical insurance status. Results: South Africa has 62 PCI-facilities. Gauteng has the most PCI-facilities (n = 28) while the Northern Cape has none. Most PCI-facilities (n = 48; 77%) are owned by the private sector. A disparity exists between the number of private and state-owned PCI-facilities when compared to the poverty (r = 0.01; p = 0.17) and insurance status of individuals (r = -0.4; p = 0.27). Conclusion: For many South Africans, access to PCI-facilities and primary PCI is still impossible given their socio-economic status or geographical locale. Research is needed to determine the specific PCI-facility needs based on geographic and epidemiological aspects, and to develop a contextualised solution for South Africans suffering a myocardial infarction.

The proportion of South Africans living within 60 and 120 minutes of a percutaneous coronary intervention facility

Abstract: Introduction: Timely reperfusion (preferably via percutaneous coronary intervention (PCI)) following myocardial infarction improves mortality. Emergency medical services play a pivotal role in recognising and transporting patients with ST-elevation myocardial infarction directly to a PCI facility to avoid delays to reperfusion. Access to PCI is, in-part, dependant on the geographic distribution of patients around PCI facilities. The aim of this study was to determine the proportion of South Africans living within 60 and 120 minutes to a PCI facility. Methods: PCI facility and population data were subjected to proximity analysis to determine the average drive times from municipal ward centroids to PCI facilities for each province in South Africa. Thereafter, the population of each ward living within 60 and 120 minutes of a PCI facility was extrapolated. Results: Approximately, 53.8% and 71.53% of the South African population lives within 60 and 120 minutes of a PCI facility. The median (IQR, range) drive times and distances to a PCI facility are 100 minutes (120.4 min, 0.7 min – 751.8 min) across 123.6km (157.6km, 0.3km – 940.8km).. Conclusion: Based on the proximity of South Africans to PCI facilities, it seems possible that most patients could receive timely PCI within 120 minutes of first medical contact. However, this may be unlikely for some due to a lack of medical insurance, under-developed referral networks or other system delays. Coronary..

A registry-based observational study comparing emergency calls assessed by emergency medical dispatchers with and without support by registered nurses

Background The requirement concerning formal education for emergency medical dispatcher (EMD) is debated and varies, both nationally and internationally. There are few studies on the outcomes of emergency medical dispatching in relation to professional background. This study aimed to compare calls handled by an EMD with and without support by a registered nurse (RN), with respect to priority level, accuracy, and medical condition. Methods A retrospective observational study, performed on registry data from specific regions during 2015. The ambulance personnel's first assessment of the priority level and medical condition was used as the reference standard. Outcomes were: the proportion of calls dispatched with a priority in concordance with the ambulance personnel's assessment; over- and undertriage; the proportion of most adverse over- and undertriage; sensitivity, specificity and predictive values for each of the ambulance priorities; proportion of calls dispatched with a medical condition in concordance with the ambulance personnel's assessment. Proportions were reported with 95% confidence intervals. chi(2)-test was used for comparisons. P-levels < 0.05 were regarded as significant. Results A total of 25,025 calls were included (EMD n = 23,723, EMD + RN n = 1302). Analyses relating to priority and medical condition were performed on 23,503 and 21,881 calls, respectively. A dispatched priority in concordance with the ambulance personnel's assessment were: EMD n = 11,319 (50.7%) and EMD + RN n = 481 (41.5%) (p < 0.01). The proportion of overtriage was equal for both groups: EMD n = 5904, EMD + RN n = 306, (26.4%) p = 0.25). The proportion of undertriage for each group was: EMD n = 5122 (22.9%) and EMD + RN n = 371 (32.0%) (p < 0.01). Sensitivity for the most urgent priority was 54.6% for EMD, compared to 29.6% for EMD + RN (p < 0.01), and specificity was 67.3% and 84.8% (p < 0.01) respectively. A dispatched medical condition in concordance with the ambulance personnel's assessment were: EMD n = 13,785 (66.4%) and EMD + RN n = 697 (62.2%) (p = 0.01). Conclusions A higher precision of emergency medical dispatching was not observed when the EMD was supported by an RN. How patient safety is affected by the observed divergence in dispatched priorities is an area for future research.Peer reviewe

Finnish and Swedish prehospital emergency care providers' knowledge and attitudes towards pressure ulcer prevention

Background: Despite the knowledge that transportation by emergency medical services may increase the risk of pressure ulcers (PU), there is still lack of knowledge about the possibility of prehospital emergency care providers to be a part of preventing and reducing the risk of PUs. Methods: A survey was carried out during 2017 in Finland and Sweden. Validated questionnaires were used. Results: A total of 179 (72.7%) Finnish and 188 (28.8%) Swedish prehospital emergency care providers participated in the study. The overall rate of correct answers and the mean total knowledge score was 58.8% (SD 21.8), 20/34, in the Finnish group and 70.5% (SD 15.7), 24/34, in the Swedish group (p < 0.000). The percent of the total and the mean attitude score was in the Finnish group 71.3% (SD 0.48), 37.1/52, and in the Swedish group 69.4% (SD 0.77), 36.1/52 (p < 0.813). Half of the Finnish and most of the Swedish participants felt they needed more education about PUs (Fin 50.2% & Swe: 76.0%). Conclusions: Prehospital emergency care providers don't see themselves as responsible for PU prevention. Therefore, there is a need for increasing the level of knowledge on PU prevention and classification among prehospital emergency care providers. They could play a key role in developing methods to improve PU prevention and identifying patients in risk of developing PUs.Peer reviewe
