Non-technical skills of Norwegian medical students at different training sites: a comparative, observational cohort study.

PURPOSE: Mastering non-technical skills (NTS) is a fundamental part of the training of new physicians to perform effectively and safely in the medical practice environment. Ideally, they learn these skills during medical school. Decentralized medical education is being implemented increasingly worldwide. Two of the three training sites studied, Bodø (a regional hospital) and Finnmark (a rural local hospital), implemented decentralized medical education. The third training site was the main campus in Tromsø, located at an urban university hospital. The training in Finnmark emphasised training in non-technical skills using simulation to a larger extent than the two other university campuses. This study aimed to compare the NTS performance of medical students in their last year of education at three different training sites of the same university. METHODS: This blinded cohort study included students from the three training sites who participated in identical multi-professional simulations over a six-year period. Eight raters evaluated the video recordings of eight students from each training site using the Norwegian Medical Students Non-Technical Skills (NorMS-NTS) tool. The NorMS-NTS tool, which comprises four categories and 13 elements, assesses the NTS of Norwegian medical students and assigns an overall global score. Pairwise significant differences in the NTS performance levels between the training sites studied were assessed using Tukey's test. RESULTS: The overall NTS performance levels of the medical students from Finnmark (mean 4.5) were significantly higher than those of the students from Tromsø (mean 3.8) and Bodø (mean 3.5). Similarly, the NTS performance levels at category-level of the students in Finnmark were significantly higher than those of the students from Bodø and Tromsø. Except for one category, no significant differences were observed between the students from Bodø and Tromsø in terms of the overall or category-level NTS performance. CONCLUSION: The NTS performance levels of the medical students from Finnmark, which implements rural, decentralized medical education, were significantly higher than those of the students from Tromsø and Bodø.

Do emergency medical dispatchers choose the same response to serious injury in men and women - a qualitative study.

BACKGROUND: Recent research has indicated that sex is an important determinant of emergency medical response in patients with possible serious injuries. Men were found to receive more advanced prehospital treatment and more helicopter transportation and trauma centre destinations and were more often received by an activated trauma team, even when adjusted for injury mechanism. Emergency medical dispatchers choose initial resources when serious injury is suspected after a call to the emergency medical communication centre. This study aimed to assess how dispatchers evaluate primary responses in trauma victims, with a special focus on the sex of the victim. METHODS: Emergency medical dispatchers were interviewed using focus groups and a semistructured interview guide developed specifically for this study. Two vignettes describing typical and realistic injury scenarios were discussed. Verbatim transcripts of the conversations were analysed via systematic text condensation. The findings were reported in accordance with the Consolidated Criteria for Reporting Qualitative Studies (COREQ) checklist. RESULTS: The analysis resulted in the main category "Tailoring the right response to the patient", supported by three categories "Get an overview of location and scene safety", "Patient condition" and "Injury mechanism and special concerns". The informants consistently maintained that sex was not a relevant variable when deciding emergency medical response during dispatch and claimed that they rarely knew the sex of the patient before a response was implemented. Some of the participants also raised the question of whether the Norwegian trauma criteria reliably detect serious injury in women. CONCLUSIONS: The results indicate that the emergency medical response is largely based on the national trauma criteria and that sex is of little or no importance during dispatch. The observed sex differences in the emergency medical response seems to be caused by other factors during the emergency medical response phase.

The development of a tool to assess medical students' non-technical skills - The Norwegian medical students' non-technical skills (NorMS-NTS).

PURPOSE: New physicians need to master non-technical skills (NTS), as high levels of NTS have been shown to increase patient safety. It has also been shown that NTS can be improved through training. This study aimed to establish the necessary NTS for Norwegian medical students to create a tool for formative and summative assessments. METHODS: Focus group interviews were conducted with colleagues and patients of newly graduated physicians. Interviews were then analyzed using card sort methods, and the identified NTS were used to establish a framework. Focus groups commented on a prototype of an NTS assessment tool. Finally, we conducted a search of existing tools and literature. The final tool was developed based on the combined inputs. RESULTS: We created Norwegian medical students' non-technical skills (NorMS-NTS) assessment tool containing four main categories; together comprising 13 elements and a rating scale for the NTS of the person observed. CONCLUSIONS: The NorMS-NTS represents a purpose-made tool for assessing newly graduated physicians' NTS. It is similar to existing assessment tools but based on domain-specific user perspectives obtained through focus group interviews and feedback, integrated with results from a literature search, and with consideration of existing NTS tools.

Collecting evidence of validity for an assessment tool for Norwegian medical students' non-technical skills (NorMS-NTS): usability and reliability when used by novice raters.

BACKGROUND: The NorMS-NTS tool is an assessment tool for assessing Norwegian medical students' non-technical skills (NTS). The NorMS-NTS was designed to provide student feedback, training evaluations, and skill-level comparisons among students at different study sites. Rather than requiring extensive rater training, the tool should capably suit the needs of busy doctors as near-peer educators. The aim of this study was to examine the usability and preliminary assess validity of the NorMS-NTS tool when used by novice raters. METHODS: This study focused on the usability of the assessment tool and its internal structure. Three raters used the NorMS-NTS tool to individually rate the team leader, a medical student, in 20 video-recorded multi-professional simulation-based team trainings. Based on these ratings, we examined the tools' internal structure by calculating the intraclass correlation coefficient (ICC) (version 3.1) interrater reliability, internal consistency, and observability. After the rating process was completed, the raters answered a questionnaire about the tool's usability. RESULTS: The ICC agreement and the sum of the overall global scores for all raters were fair: ICC (3,1) = 0.53. The correlation coefficients for the pooled raters were in the range of 0.77-0.91. Cronbach's alpha for elements, categories and global score were mostly above 0.90. The observability was high (95%-100%). All the raters found the tool easy to use, none of the elements were redundant, and the written instructions were helpful. The raters also found the tool easier to use once they had acclimated to it. All the raters stated that they could use the tool for both training and teaching. CONCLUSIONS: The observed ICC agreement was 0.08 below the suggested ICC level for formative assessment (above 0.60). However, we know that the suggestion is based on the average ICC, which is always higher than a single-measure ICC. There are currently no suggested levels for single-measure ICC, but other validated NTS tools have single-measure ICC in the same range. We consider NorMS-NTS as a usable tool for formative assessment of Norwegian medical students' non-technical skills during multi-professional team training by raters who are new to the tool. It is necessary to further examine validity and the consequences of the tool to fully validate it for formative assessments.

Trauma team training in Norwegian hospitals: an observational study.

BACKGROUND: Traumatic injuries are a leading cause of deaths in Norway, especially among younger males. Trauma-related mortality can be reduced by structural measures, such as organization of a trauma system. Many hospitals in Norway treat few seriously injured patients, one of the reasons for development of the Norwegian trauma system. Since its implementation, there has been continuous improvement of this system, including trauma team training. Regular trauma team training is compulsory, with the aims of compensating for lack of experience and maintaining competence. The purpose of this study was to present an overview of current trauma team training activities in Norway. METHODS: For this observational study, the authors developed an online questionnaire and mailed it to local trauma coordinators from 38 Norwegian hospitals-including four trauma centers and 34 acute hospitals with trauma function. The study was performed during April-June 2020, with a two-month response window. Trauma team training frequency was assessed in four predefined intervals: < 5, 5-9, 10-15 and > 15 times per year. The response rate was 33 of 38, 87%. RESULTS: All responding hospitals conducted regular trauma team training. The frequency of training increased significantly from 2013 to 2020 (Chi square test, Chi2 8.33, p = 0.04). All hospitals described a quite homogenous approach. The trauma centres trained more frequently as compared to the acute care hospitals (Chi square test, Chi2 8.24, p = 0.04). CONCLUSIONS: All responding hospitals performed regular trauma team training using a homogenous approach, which is in line with previous assessments. We observed a minor improvement in frequency compared to prior assessments. Our findings suggest that Norwegian trauma teams likely maintain their competence through team training. All hospitals followed the current recommendations from the National Trauma Plan.

Epidemiology of trauma in the subarctic regions of the Nordic countries.

BACKGROUND: The northern regions of the Nordic countries have common challenges of sparsely populated areas, long distances, and an arctic climate. The aim of this study was to compare the cause and rate of fatal injuries in the northernmost area of the Nordic countries over a 5-year period. METHODS: In this retrospective cohort, we used the Cause of Death Registries to collate all deaths from 2007 to 2011 due to an external cause of death. The study area was the three northernmost counties in Norway, the four northernmost counties in Finland and Sweden, and the whole of Iceland. RESULTS: A total of 4308 deaths were included in the analysis. Low energy trauma comprised 24% of deaths and high energy trauma 76% of deaths. Northern Finland had the highest incidence of both high and low energy trauma deaths. Iceland had the lowest incidence of high and low energy trauma deaths. Iceland had the lowest prehospital share of deaths (74%) and the lowest incidence of injuries leading to death in a rural location. The incidence rates for high energy trauma death were 36.1/100000/year in Northern Finland, 15.6/100000/year in Iceland, 27.0/100000/year in Northern Norway, and 23.0/100000/year in Northern Sweden. CONCLUSION: We found unexpected differences in the epidemiology of trauma death between the countries. The differences suggest that a comparison of the trauma care systems and preventive strategies in the four countries is required.

Psychoactive substances have major impact on injuries in rural arctic Norway - A prospective observational study.

BACKGROUND: Rural areas have increased injury mortality with a high pre-hospital death rate. Knowledge concerning the impact of psychoactive substances on injury occurrence is lacking for rural arctic Norway. These substances are also known to increase pre-, per- and postoperative risk. The aim was by prospective observational design to investigate the prevalence and characteristics of psychoactive substance use among injured patients in Finnmark county. METHODS: From January 2015 to August 2016, patients ≥18 years admitted to hospitals in Finnmark due to injury were approached when competent. Blood was analysed for ethanol, sedatives, opioids, hypnotics and illicit substances in consenting patients, who completed a questionnaire gathering demographic factors, self-reported use/behaviour and incident circumstances. RESULTS: In 684 injured patients who consented to participation (81% consented), psychoactive substances were detected in 35.7%, alcohol being the most prevalent (23%). Patients in whom substances were detected were more often involved in violent incidents (odds ratio 8.92 95% confidence interval 3.24-24.61), indicated harmful use of alcohol (odds ratio 3.56, 95% confidence interval 2.34-5.43), reported the incident being a fall (odds ratio 2.21, 95% confidence interval 1.47-3.33) and presented with a reduced level of consciousness (odds ratio 3.91, 95% confidence interval 1.58-9.67). Subgroup analysis revealed significant associations between testing positive for a psychoactive substance and being diagnosed with a head injury or traumatic brain injury. CONCLUSION: A significant proportion of injured patients had used psychoactive substances prior to admission. Use was associated with violence, falls, at-risk alcohol consumption, decreased level of consciousness on admittance and head injury.

Increased risk of fatal paediatric injuries in rural Northern Norway.

BACKGROUND: Finnmark, Northern Norway, had a mortality rate for paediatric injury in 1998-2007 that was more than twice the national average. We investigated whether this rate had decreased in 2008-2015 after improvements in emergency care. We also compared the mortality rate to rates of non-fatal injury and trauma team activation both regionally and in Norway. METHODS: The study was based on 4 national registries. Mortality and injury rates were calculated per 100 000 persons per year. The study population was divided into age groups; 0-5, 6-10, 11-15 and 16-17 years. RESULTS: Between 1998-2007 and 2008-2015 there was an overall decrease in paediatric mortality rate due to external causes in Norway in total from 7.1 to 4.0. Despite this, in 2008-2015, the mortality rate remained 2.5 times higher in Finnmark than in Norway (9.7, RR = 2.5 CI 1.4-4.3, P = 0.001), similar to findings for 1998-2007. Finnmark had half the rate of non-fatal injuries in 1999-2007 (5052, RR = 0.6, 95% CI 0.6-0.7, P < 0.001) and in 2008-2015 (3893, RR = 0.5, 95% CI 0.5-0.6, P < 0.001) as in Norway. The rate of trauma team activation was similar in Finnmark and Norway. CONCLUSIONS: The risk of injury-related death remained significantly higher, while the overall risk of non-fatal injury was significantly reduced for children in rural Northern Norway. Thus, injuries in this rural area seem to be less frequent but more severe. There is a need for detailed examination of each death to determine possible preventive measures.

Fatalities and personal injuries from the use of ATVs and snowmobiles in Northern Norway in 2013-14. / Dødsfall og personskader ved bruk av ATV og snøscooter i Nord-Norge i 2013­14.

BACKGROUND: Previous studies have shown a high occurrence of injuries and deaths related to the use of snowmobiles and other off-road vehicles in Northern Norway. No public statistics are available to permit monitoring of these findings over time. The objective of our study was to provide new figures for the prevalence of injuries and deaths from the use of snowmobiles and other off-road vehicles, and assess the consistency between different sources of data. MATERIAL AND METHOD: Information on registered deaths and personal injuries requiring hospitalisation in Northern Norway in the period 1 January 2013-31 December 2014 was collected from the police and hospitals. We also searched through open online sources. RESULTS: We found 7 deaths and 87 personal injuries requiring hospitalisation: 13 incidents with ATVs and 81 involving snowmobiles. Median age was 31.5 years, and 41 (44 %) victims were below 30 years of age. All the fatalities and 66 (76 %) of those injured were men. Altogether 42 (45 %) of the incidents had occurred in Finnmark county. Of the seven fatalities, the police found six in their records and the hospitals found two. In searching through open online sources we found one further ATV-related and three snowmobile-related fatalities in the same region and period. INTERPRETATION: No reliable records of fatalities and personal injuries resulting from the use of snowmobiles and ATVs are available. The findings of this study may serve as a reference point for preventive efforts by the police and health services and for purposes of further study.

Systematic reporting to improve the emergency medical response to major incidents: a pilot study.

BACKGROUND: Major incidents affect us globally, and are occurring with increasing frequency. There is still no evidence-based standard regarding the best medical emergency response to major incidents. Currently, reports on major incidents are non-standardised and variable in quality. This pilot study examines the first systematic reports from a consensus-based, freely accessible database, aiming to identify how descriptive analysis of reports submitted to this database can be used to improve the major incident response. METHODS: Majorincidentreporting.net is a website collecting reports on major incidents using a standardised template. Data from these reports were analysed to compare the emergency response to each incident. RESULTS: Data from eight reports showed that effective triage by experienced individuals and the use of volunteers for transport were notable successes of the major incident response. Inadequate resources, lack of a common triage system, confusion over command and control and failure of communication were reported failures. The following trends were identified: Fires had the slowest times for several aspects of the response and the only three countries to have a single dialling number for all three emergency services had faster response times. Helicopter Emergency Medical services (HEMS) were used for transport and treatment in rural locations and for triage and treatment in urban locations. In two incidents, a major incident was declared before the arrival of the first Emergency Medical Services (EMS) personnel. CONCLUSION: This study shows that we can obtain relevant data from major incidents by using systematic reporting. Though the sample size from this pilot study is not large enough to draw any specific conclusions it illustrates the potential for future analyses. Identified lessons could be used to improve the emergency medical response to major incidents.

A nationwide survey of first aid training and encounters in Norway.

BACKGROUND: Bystander first aid can improve survival following out-of-hospital cardiac arrest or trauma. Thus, providing first aid education to laypersons may lead to better outcomes. In this study, we aimed to establish the prevalence and distribution of first aid training in the populace, how often first aid skills are needed, and self-reported helping behaviour. METHODS: We conducted a telephone survey of 1000 respondents who were representative of the Norwegian population. Respondents were asked where and when they had first aid training, if they had ever encountered situations where first aid was necessary, and stratified by occupation. First aid included cardio-pulmonary resuscitation (CPR) and basic life support (BLS). To test theoretical first aid knowledge, respondents were subjected to two hypothetical first aid scenarios. RESULTS: Among the respondents, 90% had received first aid training, and 54% had undergone first aid training within the last 5 years. The workplace was the most common source of first aid training. Of the 43% who had been in a situation requiring first aid, 89% had provided first aid in that situation. There were considerable variations among different occupations in first aid training, and exposure to situations requiring first aid. Theoretical first aid knowledge was not as good as expected in light of the high share who had first aid training. In the presented scenarios 42% of respondent would initiate CPR in an unconscious patient not breathing normally, and 46% would provide an open airway to an unconscious road traffic victim. First aid training was correlated with better theoretical knowledge, but time since first aid training was not. CONCLUSIONS: A high proportion of the Norwegian population had first aid training, and interviewees reported high willingness to provide first aid. Theoretical first aid knowledge was worse than expected. While first aid is part of national school curriculum, few have listed school as the source for their first aid training.

Emergency medicine in the general practice internship in Finnmark county. / Akuttmedisinsk turnusarbeid i Finnmark.

BACKGROUND: It is preferred that duty doctors in municipal health services participate in call-outs in emergency situations. The frequency of participation has previously been shown to vary. We wanted to examine the newly qualified doctors' expectations and experiences ­ both before and after the general practice internship ­ of emergency medicine and ambulance call-outs. MATERIAL AND METHOD: All 23 of the interns who were to undertake their general practice internship in Finnmark county in the period 2015­16 answered a questionnaire and participated in a focus group interview before the start of the internship. Twenty-one of the interns participated in the focus group interview after completing the internship. Each doctor took part in two interviews. We analysed the transcripts from the focus group interviews using the grounded theory method. RESULTS: The responses from the questionnaire before the general practice internship showed that the interns felt they needed more training in intravenous cannulation and in teamwork. Their expectations in connection with the challenges of call-outs are best characterised by the core category 'Can I do anything useful?' from the focus groups before the internship. After the internship, however, the core category 'It all went well in the end', was the best fit. Due to short transport times and their knowledge of certain patients, some of the doctors chose not to take part in call-outs. INTERPRETATION: During the general practice internship, the interns were initially anxious about whether they might be superfluous in call-outs, but eventually found their footing in the call-out role. The study shows that there is a need for more practice in certain practical procedures, and that doctors' non-technical skills need to be improved. This can be done through training in team leader roles before the general practice internship.

Dispatch guideline adherence and response interval-a study of emergency medical calls in Norway.

BACKGROUND: The Emergency Medical Communication Centre (EMCC) operators in Norway report using the Norwegian Index for Medical Emergency Assistance (Index), a criteria-based dispatch guideline, in about 75 % of medical emergency calls. The main purpose of a dispatch guideline is to assist the operator in securing a correct response as quickly as possible. The effect of using the guideline on EMCC response interval is as yet unknown. We wanted to ascertain an objective measure of guideline adherence, and explore a possible effect on emergency medical dispatch (EMD) response interval. METHODS: Observational cross-sectional study based on digital telephone recordings and EMCC records; 299 random calls ending in acute and urgent responses from seven strategically selected EMCCs were included. Ability to confirm location and patient consciousness within an acceptable time interval and structural use of criteria cards were indicators used to create an overall guideline adherence variable. We then explored the relationship between different levels of guideline adherence and EMD response interval. RESULTS: The overall guideline adherence was 80 %. Location and patient consciousness were confirmed within 1 min in 83 % of the calls. The criteria cards were used systematically as intended in 64 % of the cases. Total median response interval was 2:28, with 2:01 for acute calls and 4:10 for urgent calls (p < 0.0005). Lower guideline adherence was associated with higher EMD response interval (p < 0.0005). CONCLUSION: The measured guideline adherence was higher than previously reported by the operators themselves. Patient consciousness was rapidly confirmed in the majority of cases. Failure to use Index criteria as intended result in delayed ambulance dispatch and a potential risk of undertriage.

Reporting Helicopter Emergency Medical Services in Major Incidents: A Delphi Study.

OBJECTIVE: Research on helicopter emergency medical services (HEMS) in major incidents is predominately based on case descriptions reported in a heterogeneous fashion. Uniform data reported with a consensus-based template could facilitate the collection, analysis, and exchange of experiences. This type of database presently exists for major incident reporting at www.majorincidentreporting.net. This study aimed to develop a HEMS-specific major incident template. METHODS: This Delphi study included 17 prehospital critical care physicians with current or previous HEMS experience. All participants interacted through e-mail. We asked these experts to define data variables and rank which were most important to report during an immediate prehospital medical response to a major incident. Five rounds were conducted. RESULTS: In the first round, the experts suggested 98 variables. After 5 rounds, 21 variables were determined by consensus. These variables were formatted in a template with 4 main categories: HEMS background information, the major incident characteristics relevant to HEMS, the HEMS response to the major incident, and the key lessons learned. CONCLUSION: Based on opinions from European experts, we established a consensus-based template for reporting on HEMS responses to major incidents. This template will facilitate uniformity in the collection, analysis, and exchange of experience.
