    Simulering som lärande inom prehospital akutsjukvård2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The overall aim of the research was to deepen the understanding of learning through simulation in prehospital emergency care.

    Method: In this research, qualitative and quantitative methods are used as well as integrative literature studies (I, II). Qualitative data from the interview studies (III, V) were analyzed by phenomenographic methodology. Quantitative data from the intervention study (IV) were analyzed using descriptive and analytical statistics.

    Results: Research on simulation and learning within the prehospital trauma care context is relatively rare (I). Simulation of realistic scenarios where the caregivers are exposed to stress contributes to strengthen caregiver knowledge, skills and experience (II). Caregivers request simulation opportunities regarding critical and emergency situations (III). They describe that learning through regular simulation provides in-depth knowledge and skills in the care of a patient exposed to high-energy trauma (V). Interventions with repeated simulation opportunities related to the care of the patient exposed to high-energy trauma give some improvement in care provided at the site of the accident (IV).

    Conclusion: Through simulation, the caregivers develop knowledge and skills and receive enhanced confidence in the care of an injured and sick patient. The research suggests several areas with potential for improvement with regard to the care of patients exposed to high-energy trauma. A model has been developed for systematic trauma simulation.

    Enhanced self-assessment of CPR by low-dose, high-frequency training2021In: International Journal of Emergency Services, ISSN 2047-0894, E-ISSN 2047-0908, Vol. 10, no 1, p. 93-100Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose was to investigate what effect an intervention of low-dose, highfrequencycardiopulmonary resuscitation (CPR) training with feedback for one month wouldhave on professionals’ subjective self-assessment skill of CPR.

    Design/methodology/approach - This study had a quantitative approach. In total, 38firefighters performed CPR for two minutes on a Resusci Anne QCPR. They then self-assessedtheir CPR through four multiple-choice questions regarding compression rate, depth, recoil, andventilation volume. After one month of low-dose, high-frequency training with visual feedback,the firefighters once more performed CPR and self-assessed their CPR.

    Findings - With one month of low-dose, high-frequency training with visual feedback, the levelof self-assessment was; 87% (n=33) correct self-assessment of compression rate, 95% (n=36)correct self-assessment of compression depth, 68% (n=26) correct self-assessment of recoil and87% (n=33) correct self-assessment of ventilations volume. The result shows a reduced numberof firefighters who overestimate their ability to perform CPR.

    Originality/value - With low-dose, high-frequency CPR training with visual feedback for amonth, the firefighters develop a good ability to self-assess their CPR to be performed withinthe guidelines. By improving their ability to self-assess their CPR quality, firefighters can selfregulatetheir compression and ventilation quality.

    Low-dose, high-frequency CPR training with feedback for firefighters2019In: International Journal of Emergency Services, ISSN 2047-0894, E-ISSN 2047-0908, Vol. 8, no 1, p. 64-72Article in journal (Refereed)
    Abstract [en]

    Purpose

    The purpose of this paper is to investigate the effects of the intervention of low-dose, high-frequency cardiopulmonary resuscitation (CPR) training with feedback for firefighters for one month.

    Design/methodology/approach

    The study had a quantitative approach. Data were collected through an intervention by means of simulation. The data collection consisted of a pre- and post-assessment of 38 firefighter’s CPR performance.

    Findings

    There was a statistically significant improvement from pre- to post-assessment regarding participants’ compression rates. Compression depth increased statistically significantly to average 2 mm too deep in the group. Recoil decreased in the group with an average of 1 mm for the better. There was a statistically significant improvement in participants’ ventilation volume from pre- to post-assessment.

    Originality/value

    Prehospital staff such as firefighters, police, and ambulance perform CPR under less than optimal circumstances. It is therefore of the utmost importance that these professionals are trained in the best possible way. The result of this study shows that low-dose, high-frequency CPR training with an average of six training sessions per month improves ventilation volume, compression depth, rate, and recoil. This study concludes that objective feedback during training enhances the firefighters’ CPR skills which in turn also could be applied to police and ambulance CPR training.

    Nurse students learning acute care by simulation: Focus on observation and debriefing2017In: Nurse Education in Practice, ISSN 1471-5953, E-ISSN 1873-5223, Vol. 24, p. 6-13Article in journal (Refereed)
    Abstract [en]

    Introduction:

    Simulation creates the possibility to experience acute situations during nursing education which cannot easily be achieved in clinical settings.

    Aim:

    To describe how nursing students learn acute care of patients through simulation exercises, based on observation and debriefing.

    Design:

    The study was designed as an observational study inspired by an ethnographic approach.

    Method:

    Data was collected through observations and interviews. Data was analyzed using an interpretive qualitative content analysis.

    Results:

    Nursing students created space for reflection when needed. There was a positive learning situation when suitable patient scenarios were presented. Observations and discussions with peers gave the students opportunities to identify their own need for knowledge, while also identifying existing knowledge. Reflections could confirm or reject their preparedness for clinical practice. The importance of working in a structured manner in acute care situations became apparent. However, negative feedback to peers was avoided, which led to a loss of learning opportunity.

    Conclusion:

    High fidelity simulation training as a method plays an important part in the nursing students' learning. The teacher also plays a key role by asking difficult questions and guiding students towards accurate knowledge. This makes it possible for the students to close knowledge gaps, leading to improved patient safety.

    Empowerment in the perioperative dialog2021In: Nursing Open, E-ISSN 2054-1058, Vol. 8, no 1, p. 96-103Article in journal (Refereed)
    Abstract [en]

    Aim: To describe how the nurse anaesthetist empowers the patient in the perioperative dialogue. Design: A qualitative descriptive design with interviews with 12 nurse anaesthetist (NA). Method: A hermeneutic text interpretation with a foundation in Gibson's empowerment model. Result: The results highlight Gibson's nursing domain: Helper, Supporter, Counsellor, Educator, Resource Consultant, Resource Mobilizer, Facilitator, Enabler and Advocate. The overall understanding is revealed as a relationship can be built through closeness between the patient and the NA. The NA helps the patient master the situation by talking to and touching the patient. The patient is helped to find their own strengths and to cope with their fears. The patients decide over their own bodies. When the patients do not want to or cope with protecting themselves, the NA protects and represents the patient.

    Validating peer-led assessments of CPR performance2020In: Resuscitation Plus, E-ISSN 2666-5204, Vol. 3, article id 100022Article in journal (Refereed)
    Abstract [en]

    Background

    A patient’s survival from cardiac arrest is improved if they receive good quality chest compressions as soon as possible. During cardiopulmonary resuscitation (CPR) training subjective assessments of chest compression quality is still common. Recently manikins allowing objective assessment have demonstrated a degree of variance with Instructor assessment. The aim of this study was to compare peer-led subjective assessment of chest compressions in three groups of participants with objective data from a manikin.

    Method

    This was a quantitative multi-center study using data from simulated CPR scenarios. Seventy-eight Instructors were recruited, from different backgrounds; lay persons, hospital staff and emergency services personnel. Each group consisted of 13 pairs and all performed 2 ​min of chest compressions contemporaneously by peers and manikin (Brayden PRO®). The primary hypothesis was subjective and objective assessment methods would produce different test outcomes.

    Results

    13,227 chest compressions were assessed. The overall median score given by the manikin was 88.5% (interquartile range 71.75–95), versus 92% (interquartile range 86.75–98) by observers. There was poor correlation in scores between assessment methods (Kappa −0.051 – +0.07). Individual assessment of components within the manikin scores demonstrated good internal consistency (alpha ​= ​0.789) compared to observer scores (alpha ​= ​0.011).

    Conclusion

    Observers from all backgrounds were consistently more generous in their assessment when compared to the manikin. Chest compressions quality influences outcome following cardiac arrest, the findings of this study support increased use of objective assessment at the earliest opportunity, irrespective of background.

    Ethical dilemmas in prehospital emergency care – from the perspective of specialist ambulance nurse students2018In: International Journal of Ethics Education, ISSN 2363-9997, Vol. 3, no 2, p. 181-192Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to describe specialist ambulance nurse students’ experiences of ethical conflicts and dilemmas in prehospital emergency care. In the autumn of 2015, after participating in a mandatory lecture on ethics, 24 specialist ambulance nurse (SAN) students reported experiences and interpretations concerning conflicts and ethical dilemmas from prehospital emergency care. The text consisted of 24 written critical incidents which were interpreted using hermeneutic text interpretation. The text revealed three themes: Not safeguarding a patient’s body and identity; Not agreeing on the care actions; and Not treating the patient with dignity. The SANs experiences ethical dilemmas and conflict of values when they witness how others violate a patient’s dignity. Discussion and reflection is based on ethical conflicts and dilemmas experienced when students see how caregivers do not safeguard the patient’s body or identity. When caregivers have a conflicting will, it results in patients not being treated in an ethical manner. Also, seeing how caregivers put themselves in a power position over patients is described as an ethical dilemma that students experience when they choose not to intervene.

    The prehospital assessment of severe trauma patients’ by specialist ambulance nurse in Sweden-a phenomenographic study2012In: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, E-ISSN 1757-7241, Vol. 20, p. 67-Article in journal (Refereed)
    Abstract [en]

    Background

    A common feature of prehospital emergency care is the short and fragmentary patient encounters with increased demands for efficient and rapid treatment. Crucial decisions are often made and the premise is the specialist ambulance nurse’s ability to capture the situation instantaneously. The assessment is therefore a pre-requisite for decisions about appropriate actions. However, the low exposure to severe trauma cases in Sweden leads to vulnerability for the specialist ambulance nurse, which makes the assessment more difficult. Our objective was to describe specialist ambulance nurses’ perceptions of assessing patients exposed to severe trauma.

    Methods

    This study had a phenomenographic approach and was performed in 2011 as an interview study. 15 specialist ambulance nurses with a minimum of 2.5 years of experience from praxis were included. The analysis of data was performed using phenomenography according to Marton.

    Results

    The perceptions of assessing patients exposed to severe trauma were divided into: To be prepared for emergency situations, Confidence in one’s own leadership and Developing professional knowledge.

    Conclusions

    This study reveals that the specialist ambulance nurse, on the scene of accident, finds the task of assessment of severe trauma patients difficult and complicated. In some cases, even exceeding what they feel competent to accomplish. The specialist ambulance nurses feel that no trauma scenarios are alike and that more practical skills, more training, exercise and feedback are needed.

    What is dignity in prehospital emergency care?2017In: Nursing Ethics, ISSN 0969-7330, E-ISSN 1477-0989, Vol. 24, no 3, p. 268-278Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Ethics and dignity in prehospital emergency care are important due to vulnerability and suffering. Patients can lose control of their body and encounter unfamiliar faces in an emergency situation.

    OBJECTIVE: To describe what specialist ambulance nurse students experienced as preserved and humiliated dignity in prehospital emergency care.

    RESEARCH DESIGN: The study had a qualitative approach.

    METHOD: Data were collected by Flanagan's critical incident technique. The participants were 26 specialist ambulance nurse students who described two critical incidents of preserved and humiliated dignity, from prehospital emergency care. Data consist of 52 critical incidents and were analyzed with interpretive content analysis.

    ETHICAL CONSIDERATIONS: The study followed the ethical principles in accordance with the Declaration of Helsinki.

    FINDINGS: The result showed how human dignity in prehospital emergency care can be preserved by the ambulance nurse being there for the patient. The ambulance nurses meet the patient in the patient's world and make professional decisions. The ambulance nurse respects the patient's will and protects the patient's body from the gaze of others. Humiliated dignity was described through the ambulance nurse abandoning the patient and by healthcare professionals failing, disrespecting, and ignoring the patient.

    DISCUSSION: It is a unique situation when a nurse meets a patient face to face in a critical life or death moment. The discussion describes courage and the ethical vision to see another human.

    CONCLUSION: Dignity was preserved when the ambulance nurse showed respect and protected the patient in prehospital emergency care. The ambulance nurse students' ethical obligation results in the courage to see when a patient's dignity is in jeopardy of being humiliated. Humiliated dignity occurs when patients are ignored and left unprotected. This ethical dilemma affects the ambulance nurse students badly due to the fact that the morals and attitudes of ambulance nurses are reflected in their actions toward the patient.

    Ambulance nurses’ competence and perception of competence in prehospital trauma care2018In: Emergency Medicine International, ISSN 2090-2840, E-ISSN 2090-2859, Vol. 2018, article id 5910342Article in journal (Refereed)
    Abstract [en]

    Introduction. We focus on trauma care conducted in the context of a simulated traumatic event. This is in this study defined as a four-meter fall onto a hard surface, resulting in severe injuries to extremities in the form of bilateral open femur fractures, an open tibia fracture, and a closed pelvic fracture, all fractures bleeding extensively. 

    Methods. The simulated trauma care competence of 63 ambulance nurses in prehospital emergency care was quantitatively evaluated along with their perception of their sufficiency. Data was collected by means of simulated trauma care and a questionnaire. 

    Results. Life-saving interventions were not consistently performed. Time to perform interventions could be considered long due to the life-threatening situation. In comparison, the ambulance nurses’ perception of the sufficiency of their theoretical and practical knowledge and skills for trauma care scored high. In contrast, the perception of having sufficient ethical training for trauma care scored low. 

    Discussion. This study suggests there is no guarantee that the ambulance nurses’ perception of theoretical and practical knowledge and skill level corresponds with their performed knowledge and skill. The ambulance nurses rated themselves having sufficient theoretical and practical knowledge and skills while the score of trauma care can be considered quite low.

    Effect of repeated simulation on the quality of trauma care2017In: Clinical Simulation in Nursing, ISSN 1876-1399, E-ISSN 1876-1402, Vol. 13, no 12, p. 601-608Article in journal (Refereed)
    Abstract [en]

    Background

    Simulation participants are not dependent on learning during an actual clinical situation. This allows for a learning environment that can be constructed to meet the knowledge and experience needs of the participant. Simulations in a prehospital emergency are an ideal way to address these needs without risking patient safety.

    Method

    Nurses in prehospital emergency care (n = 63) participated in simulation interventions. During the simulation, the performed trauma care was assessed in two groups of participants with different frequency of simulation.

    Results

    Several statistically significant differences and clinical improvements were found within and between the groups. Differences were noted in specific assessments, examinations, care actions, and time from assessment to action.

    Conclusion

    The result suggested that repeated simulation may contribute to a clinical improvement in trauma care, and more frequent simulation may led to even greater improvements.

    Cardiopulmonary resuscitation quality during CPR practice versus during a simulated life-saving event2018In: International Journal of Occupational Safety and Ergonomics, ISSN 1080-3548, E-ISSN 2376-9130, Vol. 24, no 4, p. 652-655Article in journal (Refereed)
    Abstract [en]

    Introduction. As a part of the emergency medical services, the Swedish fire brigade can increase the survival rate in out-of-hospital cardiac arrests.

    Aim. To compare the quality of cardiopulmonary resuscitation (CPR) performed by firefighters at a routine CPR practice versus when involved in a simulated life-saving event.

    Methods. In this study, 80 firefighters divided into two groups performed CPR according to guidelines: one group indoors during a routine training session; the other group outdoors during a smoke diving exercise wearing personal protective clothing and self-contained breathing apparatus. Descriptive and inferential statistics were used to analyze the data.

    Results. The results showed a tendency for the outdoor group to perform CPR with better ventilation and compression quality, as compared to the indoor group. The ventilation of the manikin was not hampered by the firefighters wearing personal protective clothes and self-contained breathing apparatus, as the Swedish firefighters remove their facial mask and ventilate the patient with their mouth using a pocket mask.

    Conclusions. Overall, the results in both groups showed a high quality of CPR which can be related to the fire brigade training and education traditions. CPR training is regularly performed, which in turn helps to maintain CPR skills.

    CPR performed in battlefield emergency care2019In: Australasian Journal of Paramedicine, ISSN 2202-7270, Vol. 16, p. 1-9Article in journal (Refereed)
    Abstract [en]

    Introduction

    During military missions medical care is provided to military personnel as well as civilians. Although cardiopulmonary resuscitation (CPR) may not be a common task in a military field hospital, all personnel need to be trained to deal with cardiac arrest.

    Methods

    This study was a comparative simulation study. Participants (n=36) from the Swedish armed forces performed CPR for 2 minutes at one of three different locations: at ground level, a military bed, or a transportable military stretcher. Compression depth and rate after 2 minutes of CPR and at the time of the participants’ own request to be relieved were measured. Descriptive and inferential analysis was conducted.

    Results

    There is a direct correlation between compression depth and working level, concluding that the higher working level, the lower the compression depth. There is in total an overall low percentage of participants within limits for correctly conducted CPR regarding both compression depth and rate. Time to fatigue is related to working level, where increased level results in early fatigue.

    Conclusion

    The quality of CPR is affected by the level at which it is performed. The quality of CPR was satisfactory when working at ground level, but suboptimal when working at hospital bed level or military stretcher level. When working at raised levels, participants appeared to misjudge their own compression depth and rate. This may indicate that changes are needed when CPR is practised in the military hospital setting. Future studies regarding the use footstools are required due to the height of military beds and transportable stretchers.

    Military medical personnel's perceptions of treating battle injuries2019In: Journal of military and veterans health, ISSN 1835-1271, E-ISSN 1839-2733, Vol. 27, no 2, p. 10-17Article in journal (Refereed)
    Abstract [en]

    Purpose: To evaluate military personnel’s self-rated perceptions of their knowledge, experience and training after high-fidelity battle injury simulation.

    Design: 26 military medical personnel participated in this quantitative study. Data was collected using a questionnaire after a six-day exercise where participants self-rated 10 statements regarding having sufficient medical, practical and ethical knowledge, experience and training. Descriptive and inferential analyses were conducted to obtain the results.

    Results: Nurses rated themselves statistically significantly higher than medics in having sufficient medical knowledge and experience, practical knowledge, experience and training, as well as ethical knowledge and experience. The nurses also rated themselves statistically significantly higher than physicians in having practical knowledge, experience and training. Physicians’ self-rated perception was low regarding sufficient knowledge, experience and training in practical skills. Physicians, nurses and medics all reported low ratings for sufficient training in ethical issues.

    Discussion: Military medical personnel are required to have the knowledge and skills to work autonomously in challenging and threatening environments. For personnel that seldom see battlefield-like injuries, a clinical placement in a country with a high frequency of battlefield-like injuries would be advisable. A comparison between subjective and objective assessments may identify deficiencies in competence, which can negatively impact quality of care.

    Prehospital CPR training performed with visual feedback2018In: Disaster and Emergency Medicine Journal, ISSN 2451-4691, Vol. 3, no 2, p. 41-45Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Swedish firefighters are a part of the emergency medical services. Therefore, they perform prehospital cardiopulmonary resuscitation (CPR) on a regular basis. Training becomes crucial for maintaining the CPR skills and increasing the patients’ chances of survival. Training with visual feedback is for Swedish firefighters a new way of training CPR. The aim of this study was to evaluate firefighters’ perception of a CPR manikin with visual feedback.

    METHOD: This study had a qualitative approach. Data were collected by interviews with 16 firefighters after performing CPR on a manikin with visual feedback. The data were analyzed with a manifest content analysis.

    RESULTS: Visual feedback makes it easy to identify and maintain correct compression rate. There is a need for identifying too deep compressions. Uncertainty regarding the closeness to the stomach arises when using the whole hand during compressions instead of just the wrist. To accomplish an open airway requires a bit of adjustment of the manikins’ head.

    DISCUSSION: To train and learn CPR is feasible with visual feedback. The firefighters can maintaing a correct compression rate and correct compression depth during the sessions. Ventilating a patient with bag-valvemask or pocket mask may require training with visual feedback to guarantee the firefighters being able to secure an open airway of the patient. All these skills are essential and improve the chance of survival for the patients.

    Simulation as a means to develop firefighters as emergency care professionals2019In: International Journal of Occupational Safety and Ergonomics, ISSN 1080-3548, E-ISSN 2376-9130, Vol. 25, no 4, p. 650-657Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of this study was to evaluate the simulated emergency care performed by firefighters and their perception of simulation as an educational method.

    METHODS: This study had a mixed method with both a quantitative and a qualitative approach. Data were collected by simulation assessment, a questionnaire, and written comments. Descriptive analysis was conducted on the quantitative data whereas a qualitative content analysis was conducted on the qualitative data. Finally, a contingent analysis was used where a synthesis configured both the quantitative and the qualitative results into a narrative result.

    RESULTS: The cognitive workload that firefighters face during simulated emergency care is crucial for learning. In this study, the severity and complexity of the scenarios provided were higher than expected by the firefighters. Clearly stated conditions for the simulation and constructive feedback were considered positive for learning. Patient actors induced realism in the scenario, increasing the experience of stress, in comparison to a manikin.

    CONCLUSION: To simulate in a realistic on-scene environment increases firefighters' cognitive ability to critically analyze problems and manage emergency care. Simulation of emergency care developed the firefighters as professionals.

    The nurse anesthetist perioperative dialog2020In: BMC Nursing, ISSN 1472-6955, E-ISSN 1472-6955, Vol. 19, no 1, article id 37Article in journal (Refereed)
    Abstract [en]

    Background In the perioperative dialogue, pre-, intra- and postoperatively, the patient shares their history. In the dialogue, the nurse anesthetist (NA) gets to witness the patient's experiences and can alleviate the patients' suffering while waiting for, or undergoing surgery. The aim of this study was to describe the nurse anesthetist's experiences of the perioperative dialogue. Methods The study had a qualitative design. Interviews were conducted with 12 NA and analyzed with interpretive content analysis. The methods were conducted in accordance with the COREQ guidelines. Results In the result, three categories emerge: A mutual meeting (the preoperative dialogue) where the patient and the NA through contact create a relationship. The NA is present and listens to the patient, to give the patient confidence in the NA. In the category, On the basis of the patient's needs and wishes (the intraoperative dialogue), the body language of the NA, as well as the ability to read the body language of the patient, is described as important. In the category, To create a safe situation (the postoperative dialogue) the NA ensures that the patient has knowledge of what has happened and of future care in order to restore the control to the patient. Conclusion The patient is met as a person with their own needs and wishes. It includes both a physical and a mental meeting. In a genuine relationship, the NA can confirm and unreservedly talk with the patient. When the patients leave their body and life in the hands of the NA, they can help the patients to find their inherent powers, which allows for participation in their care. Understanding the patient is possible when entering in a genuine relationship with the patient and confirm the patient. The perioperative dialogue forms a safety for the patients in the operating environment.

    To enhance the quality of CPR performed by youth layman2019In: International Journal of Emergency Medicine, ISSN 1865-1372, E-ISSN 1865-1380, Vol. 12, no 1, article id 30Article in journal (Refereed)
    Abstract [en]

    By educating laymen, survival after cardiac arrest can increase in society. It is difficult to reach the entire population with cardiopulmonary resuscitation (CPR) training. However, if 15% of the population knows how to perform CPR, an increase in short- and long-term survival in patients suffering a cardiac arrest could be seen. To educate youth is a way to reach parts of the population. This study aimed to investigate the effect of a 2-h CPR intervention for youth.

    To strengthen self-confidence as a step in improving prehospital youth laymen basic life support2020In: BMC Emergency Medicine, ISSN 1471-227X, E-ISSN 1471-227X, Vol. 20, no 1, article id 8Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    A rapid emergency care intervention can prevent the cardiac arrest from resulting in death. In order for Cardio Pulmonary Resuscitation (CPR) to have any real significance for the survival of the patient, it requires an educational effort educating the large masses of people of whom the youth is an important part. The aim of this study was to investigate the effect of a two-hour education intervention for youth regarding their self-confidence in performing Adult Basic Life Support (BLS).

    METHODS:

    A quantitative approach where data consist of a pre- and post-rating of seven statements by 50 participants during an intervention by means of BLS theoretical and practical education.

    RESULTS:

    The two-hour training resulted in a significant improvement in the participants' self-confidence in identifying a cardiac arrest (pre 51, post 90), to perform compressions (pre 65, post 91) and ventilations (pre 64, post 86) and use a defibrillator (pre 61, post 81). In addition, to have the self-confidence to be able to perform, and to actually perform, first aid to a person suffering from a traumatic event was significantly improved (pre 54, post 89).

    CONCLUSION:

    By providing youth with short education sessions in CPR, their self-confidence can be improved. This can lead to an increased will and ability to identify a cardiac arrest and to begin compressions and ventilations. This also includes having the confidence using a defibrillator. Short education sessions in first aid can also lead to increased self-confidence, resulting in young people considering themselves able to perform first aid to a person suffering from a traumatic event. This, in turn, results in young people perceiveing themselves as willing to commence an intervention during a traumatic event. In summary, when the youth believe in their own knowledge, they will dare to intervene.

    Learning by simulation in prehospital emergency care: an integrative literature review2016In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 30, no 2, p. 234-240Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Acquiring knowledge and experience on high-energy trauma is often difficult due to infrequent exposure. This creates a need for training which is specifically tailored for complex prehospital conditions. Simulation provides an opportunity for ambulance nurses to focus on the actual problems in clinical practice and to develop knowledge regarding trauma care. The aim of this study was to describe what ambulance nurses and paramedics in prehospital emergency care perceive as important for learning when participating in simulation exercises.

    METHODS: An integrative literature review was carried out. Criteria for inclusion were primary qualitative and quantitative studies, where research participants were ambulance nurses or paramedics, working within prehospital care settings, and where the research interventions involved simulation.

    RESULTS: It was perceived important for the ambulance nurses' learning that scenarios were advanced and possible to simulate repeatedly. The repetitions contributed to increase the level of experience, which in turn improved the patients care. Moreover, realism in the simulation and being able to interact and communicate with the patient were perceived as important aspects, as was debriefing, which enabled the enhancement of knowledge and skills. The result is presented in the following categories: To gain experience, To gain practice and To be strengthened by others.

    CONCLUSION: Learning through simulation does not require years of exposure to accident scenes. The simulated learning is enhanced by realistic, stressful scenarios where ambulance nurses interact with the patients. In this study, being able to communicate with the patient was highlighted as a positive contribution to learning. However, this has seldom been mentioned in a previous research on simulation. Debriefing is important for learning as it enables scrutiny of one's actions and thereby the possibility to improve and adjust one's caring. The effect of simulation exercises is important on patient outcome.

    Learning high-energy trauma care through simulation2018In: Clinical Simulation in Nursing, ISSN 1876-1399, E-ISSN 1876-1402, Vol. 17, p. 1-6Article in journal (Refereed)
    Abstract [en]

    Simulation provides the opportunity to learn how to care for patients in complex situations, such as when patients are exposed to high-energy trauma such as motor vehicle accidents. The aim of the study was to describe nurses' perceptions of high-energy trauma care through simulation in prehospital emergency care. The study had a qualitative design. Interviews were conducted with 20 nurses after performing a simulated training series. Data were analyzed using a phenomenographic method. The result indicates that simulation establishes, corrects, and confirms knowledge and skills related to trauma care in prehosp ital emergency settings. Trauma knowledge is readily available in memory and can be quickly retrieved in a future trauma situation.

    Mapping the use of simulation in prehospital care: a literature review.2014In: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, E-ISSN 1757-7241, Vol. 22, no 22, p. 12-Article in journal (Refereed)
    Abstract [en]

    Background:

    High energy trauma is rare and, as a result, training of prehospital care providers often takes place during the real situation, with the patient as the object for the learning process. Such training could instead be carried out in the context of simulation, out of danger for both patients and personnel. The aim of this study was to provide an overview of the development and foci of research on simulation in prehospital care practice.

    Methods:

    An integrative literature review were used. Articles based on quantitative as well as qualitative research methods were included, resulting in a comprehensive overview of existing published research. For published articles to be included in the review, the focus of the article had to be prehospital care providers, in prehospital settings. Furthermore, included articles must target interventions that were carried out in a simulation context.

    Results:

    The volume of published research is distributed between 1984-2012 and across the regions North America, Europe, Oceania, Asia and Middle East. The simulation methods used were manikins, films, images or paper, live actors, animals and virtual reality. The staff categories focused upon were paramedics, emergency medical technicians (EMTs), medical doctors (MDs), nurse and fire fighters. The main topics of published research on simulation with prehospital care providers included: Intubation, Trauma care, Cardiac Pulmonary Resuscitation (CPR), Ventilation and Triage.

    Conclusion:

    Simulation were described as a positive training and education method for prehospital medical staff. It provides opportunities to train assessment, treatment and implementation of procedures and devices under realistic conditions. It is crucial that the staff are familiar with and trained on the identified topics, i.e., intubation, trauma care, CPR, ventilation and triage, which all, to a very large degree, constitute prehospital care. Simulation plays an integral role in this. The current state of prehospital care, which this review reveals, includes inadequate skills of prehospital staff regarding ventilation and CPR, on both children and adults, the lack of skills in paediatric resuscitation and the lack of knowledge in assessing and managing burns victims. These circumstances suggest critical areas for further training and research, at both local and global levels.

    Caring for patients in the end-of-life from the perspective of undergraduate nursing students2020In: Nursing Forum, ISSN 0029-6473, Vol. 55, no 3, p. 433-438Article in journal (Refereed)
    Abstract [en]

    Background: Caring for patients in the end-of-life is an emotionally and physically challenging task. Therefore, undergraduate nursing students (UNS) need opportunities to learn to care for the dying patient. This study aimed to describe UNS' experiences of caring for patients at end-of-life.

    Methods: Interviews with 16 UNS in their last semester of nursing education were conducted. Data were analyzed with a phenomenological approach.

    Results: The UNS created a professional relationship with the dying patient. It meant that when the patient was unable to speak for themselves, the UNS could still meet his/her wishes and needs. The UNS believed they could take responsibility for the patient who was no longer able to take responsibility for themselves. Meeting with the patient's family could be experienced with anxiousness but was dependent on the personal chemistry between the patient's family and the UNS.

    Conclusion: The UNS creates a relationship with the patient and their family. To be knowledgeable about the patient's physical and psychosocial needs means that the UNS can support the patient in the end-of-life phase. Being close to the patient and the family results in an intensity of emotions in the care situation. The UNS can receive support from their colleagues during processing their emotions and creating an experience from their encounters with patients in end-of-life care.

    Ethics and aesthetics in injection treatments with Botox and Filler2021In: Journal of Women & Aging, ISSN 0895-2841, E-ISSN 1540-7322, Vol. 33, no 6, p. 583-595Article in journal (Refereed)
    Abstract [en]

    The medical nature of esthetic treatments is confusing, as the boundaries between medicine and beauty are unclear. A person's autonomous decision is an indicator for esthetic treatments that will improve their self-image, self-esteem and appearance to others. Robust ethical consideration is therefore necessary for the medical esthetician in each meeting with the client. This study aimed to describe medical estheticians' perceptions of ethics and esthetics in injection treatments with Botox and Filler. The results are described in Understanding what different clients desire, Reaching a mutual understanding of expectations and possibilities and Taking responsibility for beauty.

    Trauma simulation in prehospital emergency care2018In: Journal of Trauma Nursing, ISSN 1078-7496, Vol. 25, no 3, p. 201-204Article in journal (Refereed)
    Abstract [en]

    Well-educated ambulance staff is a prerequisite for high-quality prehospital trauma care. The aim of this study was to examine how nurses in the ambulance service experienced participation in trauma simulation. Sixty-one nurses, working in an emergency ambulance service, performed simulated trauma care on four different occasions and afterward rated three statements on a 5-point Likert scale. A descriptive and inferential analysis was conducted. There are statistically significant increases between the pre- and posttests regarding all three statements: I think simulation of severe trauma with manikins is realistic (0.23 or 6% increase), Simulation is a suitable method for learning severe trauma care (1.3 or 38% increase), and I am comfortable in the situation learning severe trauma care through simulation (0.74 or 19% increase). With the experience of realism in simulation, participants become more motivated to learn and prepare for future events. If the participants instead feel uncomfortable during simulation training, they focus on their own feelings instead of learning. In a realistic simulated environment, participants are prepared to understand and manage the emergency care situation in clinical work. Participants learn during simulation when they are outside their comfort zone but without being uncomfortable or experiencing anxiety.

    Higher order mining for monitoring district heating substations2019In: Proceedings - 2019 IEEE International Conference on Data Science and Advanced Analytics, DSAA 2019, Institute of Electrical and Electronics Engineers (IEEE), 2019, p. 382-391, article id 8964173Conference paper (Refereed)
    Abstract [en]

    We propose a higher order mining (HOM) approach for modelling, monitoring and analyzing district heating (DH) substations' operational behaviour and performance. HOM is concerned with mining over patterns rather than primary or raw data. The proposed approach uses a combination of different data analysis techniques such as sequential pattern mining, clustering analysis, consensus clustering and minimum spanning tree (MST). Initially, a substation's operational behaviour is modeled by extracting weekly patterns and performing clustering analysis. The substation's performance is monitored by assessing its modeled behaviour for every two consecutive weeks. In case some significant difference is observed, further analysis is performed by integrating the built models into a consensus clustering and applying an MST for identifying deviating behaviours. The results of the study show that our method is robust for detecting deviating and sub-optimal behaviours of DH substations. In addition, the proposed method can facilitate domain experts in the interpretation and understanding of the substations' behaviour and performance by providing different data analysis and visualization techniques.

    Outlier Detection for Video Session Data Using Sequential Pattern Mining2018In: ACM SIGKDD Workshop On Outlier Detection De-constructed, 2018Conference paper (Refereed)
    Abstract [en]

    The growth of Internet video and over-the-top transmission techniqueshas enabled online video service providers to deliver highquality video content to viewers. To maintain and improve thequality of experience, video providers need to detect unexpectedissues that can highly affect the viewers’ experience. This requiresanalyzing massive amounts of video session data in order to findunexpected sequences of events. In this paper we combine sequentialpattern mining and clustering to discover such event sequences.The proposed approach applies sequential pattern mining to findfrequent patterns by considering contextual and collective outliers.In order to distinguish between the normal and abnormal behaviorof the system, we initially identify the most frequent patterns. Thena clustering algorithm is applied on the most frequent patterns.The generated clustering model together with Silhouette Index areused for further analysis of less frequent patterns and detectionof potential outliers. Our results show that the proposed approachcan detect outliers at the system level.

    A Minimum Spanning Tree Clustering Approach for Outlier Detection in Event Sequences2018In: The 17th IEEE International Conference on Machine Learning and Applications Special Session on Machine Learning Algorithms, Systems and Applications, IEEE, 2018Conference paper (Refereed)
    Abstract [en]

    Outlier detection has been studied in many domains. Outliers arise due to different reasons such as mechanical issues, fraudulent behavior, and human error. In this paper, we propose an unsupervised approach for outlier detection in a sequence dataset. The proposed approach combines sequential pattern mining, cluster analysis, and a minimum spanning tree algorithm in order to identify clusters of outliers. Initially, the sequential pattern mining is used to extract frequent sequential patterns. Next, the extracted patterns are clustered into groups of similar patterns. Finally, the minimum spanning tree algorithm is used to find groups of outliers. The proposed approach has been evaluated on two different real datasets, i.e., smart meter data and video session data. The obtained results have shown that our approach can be applied to narrow down the space of events to a set of potential outliers and facilitate domain experts in further analysis and identification of system level issues.

    Trend analysis to automatically identify heat program changes2017In: Energy Procedia, Elsevier, 2017, p. 407-415Conference paper (Refereed)
    Abstract [en]

    The aim of this study is to improve the monitoring and controlling of heating systems located at customer buildings through the use of a decision support system. To achieve this, the proposed system applies a two-step classifier to detect manual changes of the temperature of the heating system. We apply data from the Swedish company NODA, active in energy optimization and services for energy efficiency, to train and test the suggested system. The decision support system is evaluated through an experiment and the results are validated by experts at NODA. The results show that the decision support system can detect changes within three days after their occurrence and only by considering daily average measurements.

    The Relation between Lean Manufacturing & Customer's Demand Uncertainty2009Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Customer Demand Uncertainty is a big obstacle for companies to sustain their competitiveness in the market that responding customer requirements becomes essential. Besides companies need to consider also their cost structures which should have in high consistency to survive as well. Lean and Agile terminologies have been investigated so far in cost and responsiveness to customer manner within internal system perspective i.e. product volume and variety. This thesis aims to link lean manufacturing steps with customer demand uncertainty condition following information systems, marketing issues and human factor for management level in framework that firm’s (manufacturer) current condition can be tested according to answers from questionnaires and implementation of assessment tables since it is used as guideline and provides on which level firms are in demand uncertainty, lean and agile manufacturing. This support enables to firms to create their own flexible leagile decoupling point according to their interior characteristics and capabilities in the market.

    Development of Software for Feature Model Rendering2006Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    This Master’s thesis is aimed at improving the management of artifacts in the context of a joint-project between Jönköping University with the SEMCO project and industrial partner, a company involved in developing software for safety components. Both have a slightly distinct interest but this project can serve both parties.

    Nowadays feature modelling is efficient way for domain analysis. The purpose of this master thesis is to analysis existing four popular feature diagrams, to find out commonalities between each of them and conclude results to give suggestions of how to use existing notation systems efficiently and according to situations.

    The developed software based on knowledge established from research analysis. Two notation systems which are suggested in research part of the thesis report are implemented in the developed software “NotationManager”. The development procedures are also described and developer choices are mentioned along with the comparisons according to the situations

    Scope of the research part as well as development is discussed. Future work for developed solution is also suggested.

    #Familygoals: Family influencers, calibrated amateurism, and justifying young digital labor2017In: Social Media and Society, ISSN 2056-3051, Vol. 3, no 2Article in journal (Refereed)
    Abstract [en]

    Following in the celebrity trajectory of mommy bloggers, global micro-microcelebrities, and reality TV families, family Influencers on social media are one genre of microcelebrity for whom the “anchor” content in which they demonstrate their creative talents, such as producing musical covers or comedy sketches, is a highly profitable endeavor. Yet, this commerce is sustained by an undercurrent of “filler” content wherein everyday routines of domestic life are shared with followers as a form of “calibrated amateurism.” Calibrated amateurism is a practice and aesthetic in which actors in an attention economy labor specifically over crafting contrived authenticity that portrays the raw aesthetic of an amateur, whether or not they really are amateurs by status or practice, by relying on the performance ecology of appropriate platforms, affordances, tools, cultural vernacular, and social capital. In this article, I consider the anatomy of calibrated amateurism, and how this practice relates to follower engagement and responses. While some follower responses have highlighted concerns over the children’s well-being, a vast majority overtly signal their love, support, and even envy toward such parenting. I draw on ethnographically informed content analysis of two group of family Influencers on social media to illustrate the enactment and value of calibrated amateurism in an increasingly saturated ecology and, investigate how such parents justify the digital labor in which their children partake to produce viable narratives of domestic life.
