- BackgroundImmersion is important for simulation-based education; however, questionnaire-based instruments to measure immersion have some limitations. The aim of the present work is to develop a new instrument to measure immersion among participants in healthcare simulation scenarios.MethodsThe instrument was developed in four phases: trigger identification, content validity scores, inter-rater reliability analysis and comparison with an existing immersion measure instrument. A modified Delphi process was used to develop the instrument and to establish validity and reliability. The expert panel consisted of 10 researchers. All the researchers in the team had previous experience of simulation in the health and/or fire and rescue services as researchers and/or educators and simulation designers. To identify triggers, the panel members independently screened video recordings from simulation scenarios. Here, a trigger is an event in a simulation that is considered a sign of reduced or enhanced immersion among simulation participants.ResultsThe result consists of the Immersion Score Rating Instrument (ISRI). It contains 10 triggers, of which seven indicate reduced and three enhanced immersion. When using ISRI, a rater identifies trigger occurrences and assigns them strength between 1 and 3. The content validity analysis shows that all the 10 triggers meet an acceptable content validity index for items (I-CVI) standard. The inter-rater reliability (IRR) among raters was assessed using a two-way mixed, consistency, average-measures intra-class correlation (ICC). The ICC for the difference between weighted positive and negative triggers was 0.92, which indicates that the raters are in agreement. Comparison with results from an immersion questionnaire mirrors the ISRI results.ConclusionsIn conclusion, we present a novel and non-intrusive instrument for identifying and rating the level of immersion among participants in healthcare simulation scenarios.

- Emergency medical care for seriously injured patients in war or warlike situations is highly important when it comes to soldiers' survival and morale. The Swedish Armed Forces sends nurses, who have limited experience of caring for injured personnel in the field, on a variety of international missions. The aim of this investigation was to identify the kind of criteria nurses rely on when assessing acute trauma and what factors are affecting the emergency care of injured soldiers. A phenomenographic research approach based on interviews was used. The database for the study consists of twelve nurses who served in Bosnia in 1994-1996. The criteria nurses rely on, when assessing acute trauma in emergency care, could be described in terms of domain-specific criteria such as a physiological, an anatomical, a causal and a holistic approach as well as contextual criteria such as being able to communicate, having a sense of belonging, the military environment, the conscript medical orderly and familiarity with health-caring activity. The present study shows that the specific contextual factors affecting emergency care in the field must also be practised before the nurse faces military emergency care situations. This calls for realistic exercises and training programs, where experience from civilian emergency care is interwoven with the knowledge specific to military medical care. © 2007 Elsevier Ltd.

- Purpose: The purpose of this paper is to demonstrate how new public management (NPM) reform from the national level is implemented as practice in a local unit within the police sector in Sweden.Design/methodology/approach: A qualitative case-study approach is applied using semi-structured interviews, participant observations and analysis of documents.Findings: The paper illustrates different kinds of resistance at the organizational level. The dominant form of resistance was found to be cultural distancing. The paper demonstrates a tendency among police officers to deal with a changing and more complex work context by embracing a traditional work role.Research limitations/implications: The paper shows that reforms that add complexity may fail because of potential contradictions and the limited capacity and motivation of employees to deal with the complexity in the manner prescribed by NPM. Practical implications: The paper shows that the popular trend to adopt multi-dimensional forms of control (for instance the balanced-scorecard approach) may fail if there is a lack of consensus about what goals and measurement are important and/or there is a lack of dialogue about how the new goals should be implemented in practice.Originality/value: Research about NPM-reforms in the police sector is rare. The original contribution of this paper is to study NPM-reforms with a focus on the role of complexity in relation to resistance.

- Recommendation systems in fashion are used to provide recommendations to users on clothing items, matching styles, and size or fit. These recommendations are generated based on user actions such as ratings, reviews or general interaction with a seller. There is an increased adoption of implicit feedback in models aimed at providing recommendations in fashion. This paper aims to understand the nature of implicit user feedback in fashion recommendation systems by following guidelines to group user actions. Categories of user actions that characterize implicit feedback are examination, retention, reference, and annotation. Each category describes a specific set of actions a user takes. It is observed that fashion recommendations using implicit user feedback mostly rely on retention as a user action to provide recommendations.

- There is a lack of knowledge about the early phase of severe infection. This report describes the early chain of care in bacteraemia as follows: (a) compare patients who were and were not transported by the Emergency Medical Services (EMS); (b) describe various aspects of the EMS chain; and (c) describe factors of importance for the delay to the start of intravenous antibiotics. It was hypothesized that, for patients with suspected sepsis judged by the EMS clinician, the delay until the onset of antibiotic treatment would be shorter.All patients in the Municipality of Gothenburg (Sweden) with a positive blood culture, when assessed at the Laboratory of Bacteriology in the Municipality of Gothenburg, from February 1 through April 30, 2012 took part in the survey.In all, 696 patients fulfilled the inclusion criteria. Their mean age was 76 years and 52% were men. Of all patients, 308 (44%) had been in contact with the EMS and/or the emergency department (ED). Of these 308 patients, 232 (75%) were transported by the EMS and 188 (61%) had “true pathogens” in blood cultures. Patients who were transported by the EMS were older, included more men, and suffered from more severe symptoms and signs.The EMS nurse suspected sepsis in only six percent of the cases. These patients had a delay from arrival at hospital until the start of antibiotics of one hour and 19 minutes versus three hours and 21 minutes among the remaining patients (P =.0006). The corresponding figures for cases with “true pathogens” were one hour and 19 minutes versus three hours and 15 minutes (P =.009).Among patients with bacteraemia, 75% used the EMS, and these patients were older, included more men, and suffered from more severe symptoms and signs. The EMS nurse suspected sepsis in six percent of cases. Regardless of whether or not patients with true pathogens were isolated, a suspicion of sepsis by the EMS clinician at the scene was associated with a shorter delay to the start of antibiotic treatment.

- Objective. Simulation based training with full-size mannequins is a prominent means of training within the healthcare sector. Prehospital missions include all parts of the healthcare process which take place before a patient is handed over to the receiving hospital. This implies that the context for prehospital care is varied and potentially challenging or dangerous in several ways. In this article we present a study which explores immersion and performance by emergency medical services (EMS) professionals in in a training situation which takes the specifics of prehospital interventions into account.Methods. The study was carried out as a field experiment at an ambulance unit. The experiment was designed to compare the differences between two types of medical scenarios: basic and contextualized. We analyzed the levels of immersion throughout the scenarios and then team performance was evaluated by independent experts. Both analyses were made by observing video recordings from multiple camera angles with a custom made analysis tool.Results. Our results show that the contextualization of a medical scenario increases both immersion as measured by the Immersion Score Rating Instrument (ISRI) and team performance as measured by the Global Rating Scale (GRS). The overall ISRI score was higher in the contextualized condition as compared to the basic condition, with an average team wise difference of 2.94 (sd = 1.45). This difference is significant using a paired, two-tailed t-test (p<.001). The GRS score was higher for overall clinical performance in the contextualized scenario with an average team wise difference of 0.83 (sd = 0.83, p=.005).Conclusions. Full-size mannequin simulation based training for EMS professionals may be enhanced by contextualizing the medical scenarios. The main benefits are that the contextualized scenarios better take prehospital medical challenges into account and allow participants to perform better.

- This paper reports on a field experiment with 12 paramedic teams (n=24) exploring how they perceive a novel training approach. The feeling of being engaged in training (i.e. being immersed) is often held forward as a major benefit of roleplaying exercises. Engagement is expected to raise the quality of training as well as improving learning and retention. However, much simulation-based training in prehospital care is decontextualized, meaning that medical care is trained without taking other characteristics of prehospital care into account. In this paper we investigate how a richer setting (contextualization), which includes more of the complicating aspects of prehospital care, affects the perceived immersion of the participants. The results show that contextualization has a significant positive impact on perceived immersion. These results are important for further studies on how to organize and design role-playing exercises.

The S.A.R.E.K Simulation Environment : Technical description of a flexible training environment for prehospital care
- 2017
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This report contains a technical description of the result of the S.A.R.E.K (Simulation – Ambulance – Research – Education - Kinship) collaboration project and the Sim2020 project. The projects are collaborations between researchers in healthcare and IT, and prehospital care practitioners, with the aim to design, develop and test a contextualized simulation environment for prehospital care. We built a simulation environment representing the full depth and width of a prehospital care process. Breadth refers to including all phases of a prehospital mission, from dispatch to handover; while depth refers to detailed representations and recreation of artefacts, information and context for each of these phases. This report outlines the details of the overall design, all equipment and practical solutions used to create this. Apart from the installation which is described in this report we have also developed methods and carried out a variety of tests and experiments which are reported elsewhere. The focus of this report is the system and its components.
