- Aims and objectives: To evaluate the effectiveness of an individualised programme to promote self-care in sleep-activity in patients with coronary artery disease. Background: Recent scientific findings have shown that low physical exercise and stress interfere with coronary artery disease patients' sleep quality and sleep efficiency independent of gender, age and co-morbidity. Design: A randomised pretest-post-test control design. Methods: Forty-seven patients who had undergone a coronary revascularisation procedure and/or pharmacological treatment three to seven weeks earlier at a general hospital were randomised to either an intervention group or a control group. Data collection was carried out by questionnaires, a study-specific sleep diary and actigraphy registration for 10 consecutive 24-hour periods, with a follow-up after three to four months. The intervention group underwent a nurse-led individualised education programme to promote self-care of sleep-activity. Sleep habits and sleep-related lifestyle together formed the basis for setting up individual goals together with the nurse. Individual advice on physical training, relaxation exercise and a CD-based relaxation programme was provided by a physiotherapist. Both groups received a brochure about sleep and stress. Results: At a three- to four-month follow-up, the main improvements were seen in the intervention group regarding sleep quality, sleep duration and sleep efficiency in the sleep diary and sleep efficiency in actigraphy. Statistical improvements in health-related quality of life were revealed. This was not so obvious in the control group. Conclusions: An individualised intervention programme to promote self-care of sleep-activity including relaxation in patients with coronary artery disease led by a nurse may improve sleep quality. However, a longitudinal study to promote self-care in sleep-activity should be performed using a larger sample and multiple sites with continuous follow-ups to determine whether any positive effects remain stable over time. Relevance to clinical practice: Implementation of a multiprofessional individualised programme to promote self-care of sleep-activity including relaxation based on patients' needs, supported by a healthcare team and led by nurses, is important in clinical practice. © 2014 John Wiley & Sons Ltd.

- A framework is needed for identifying internal and external factors essential for the nursing management of psychological supportive health care and education for patients' self-care in sleep. In order to generate more knowledge from the patient's perspective, the aim of this study was to describe how patients with coronary artery disease (CAD) perceive that their sleep is influenced by rest, activity and health in outpatient care. Qualitative interviews were performed with 33 outpatients. The data were analysed using a phenomenographic method. Three descriptive categories of the phenomenon were described: my lifestyle is reflected in my sleep behaviour, handling the practices around tiredness and sleep, and feelings of negative and positive efficacy. Feelings of tiredness, fatigue and sleepiness were different pre-sleep stages, but were also related to the patient's adaptation and recovery. Creating one's own personal time and feelings of efficacy gave an inner sense of strength which is indicated as being particularly important in managing stress and the demands of everyday life in a satisfactory manner. From a contextual, holistic perspective on health, it is important to identify the patient's needs, symptoms and intentional or unintentional self-care management strategies regarding sleep and lifestyle. To promote a positive health outcome it is essential to identify sleeplessness behaviour and perceived self-efficacy for self-care in sleep. © 2007 Nordic College of Caring Science.

- Johansson A, Karlsson J, Brödje K, Edell-Gustafsson U. International Journal of Nursing Practice 2012; 18: 44-51 Self-care strategies to facilitate sleep in patients with heart disease-A qualitative study This study aimed at exploring and describing the self-care management strategies used by patients with coronary artery disease to facilitate sleep. Qualitative interviews in a dialogue manner, in a phenomenographic reference frame analyzed according to manifest and latent principles of qualitative content analysis, were performed. A purposeful sampling technique was used including 11 patients with coronary heart disease in a Heart Medical Unit in a general hospital setting. Two main themes were identified: sleep-rhythm and sleep-hygiene including four descriptive categories. The categories reveal five basic responses including emotions, cognition, physical symptoms (reactions), behaviours and/or the sleep environment, which were related to perceived or actual presence of sleep-wake problems and health that were the underlying reason for the self-care management strategies. Basically, intervention studies that address these five responses for choice of non-pharmacological methods based on cognitive behavioural therapy provided by nurses are needed.

- Aim. To evaluate whether there are gender differences in insomnia, sleep quality, sleep efficiency (%), general arousal, disease-specific and health-related quality of life in patients with coronary artery disease, compared with an age- and gender-matched randomly selected group from the general population. Background. There are gender difference effects of sleep disturbances in the general population, but this perspective among patients with coronary artery disease has been poorly analysed. Design. In this prospective study, comparative, descriptive and model testing designs were used. Method. The patients with coronary artery disease, 556 men and 324 women aged 25–86, were compared with a matched population-based group. Data were collected by validated and reliability-tested questionnaires. Results. The prevalence of severe insomnia varied between 17–44% in all four groups. The severe insomniac coronary artery disease patients displayed a two- or threefold higher presleep arousal, had two hours shorter nocturnal sleep duration/night and were more limited in their physical exercise level than the population-based group. Gender differences in sleep quality, sleep efficiency (%) and general arousal disappeared with increased insomnia severity. Conclusions. Independent of gender, age and comorbidity, physical exercise, general arousal behaviour and delayed poststress recovery after mental stress were found to have a negative impact on the coronary artery disease patients’ sleep quality and sleep efficiency (%), interfering with their health-related quality of life. The variables significantly explained 41% of the sleep quality outcome and 29% of the sleep efficiency (%). Relevance to clinical practice. Insomnia because of hyperarousal behaviour can be an important factor in the development of an individual self-care management programme supported by a healthcare team.

- The aim of this study was to explore whether there are gender differences in sleep and health-related quality of life in patients with coronary artery disease (CAD) and a matched population-based sample and to see how subjectively rated sleep is associated with actigraphy. Secondly, to explore whether factors that predict patients sleep quality could be identified. Fifty-seven patients with stable CAD and 47 participants from a population-based sample were included. All participants completed the Uppsala Sleep Inventory (USI), the Epworth Sleepiness Scale and the SF-36. Actigraphy recordings and a sleep diary were performed for seven 24-h periods. Multiple stepwise regression analysis showed that sleep duration, sleep onset latency, nocturnal awakenings, vitality (SF-36) and body mass index explained 60% of the sleep quality outcome (USI). Sleep duration, sleep efficiency and fragmentation index assessed with actigraphy and sleep diary accounted for 36% of the sleep quality outcome (diary). The result can form the basis for a non-pharmacological, self-care programme supported and led by nurses.

Konferensbidrag (refereegranskat)abstract
- This paper reports on experiences of creating resilience-empowering simulation-gaming exercises concerning disruptions in the payment system. The aim of the exercises was to utilize gaming-simulation as a training environment where teams of practitioners can learn to develop in-depth understanding of systemic interaction (i.e., cascading effects of disruptions) and learn how to develop collaborative resilience across many different critical infrastructures. Interaction between different stakeholders in the payment system, such as business owners, banks, municipality crisis managers are considered as the foundation for building collaborative resilience. Designing the exercises in such a way that they encourage and support such interactions are therefore seen as a primary design goal. This paper describes lessons learned from the process of conducting the 17 exercises in terms of creating a well-balance simulation and an immersive experience.

- The military emergency care education of nurses is primarily concerned with the treatment of soldiers with combat-related injuries. Even though great progress has been made in military medicine, there is still the pedagogical question of what emergency care education for military nurses should contain and how it should be taught. The aim of this study was to describe and compare experiences of training emergency care in military exercises among conscript nurses with different levels of education. A descriptive study was performed to describe and compare experiences of training emergency care in military exercises among conscript nurses with different levels of education in nursing. There were statistical differences between nurses with general nursing education and nurses with a general nursing education and supplementary education. A reasonable implication of the differences is that the curriculum must be designed differently depending on the educational background of the students. Hence, there is an interaction between background characteristics, e.g., the level of previous education and differences pertaining to clinical experience of the participants, and the impact of the exercise itself.

Tidskriftsartikel (refereegranskat)abstract
- A definition of information fusion (IF) as a field of research can benefit researchers within the field, who may use such a definition when motivating their own work and evaluating the contributions of others. Moreover, it can enable researchers and practitioners outside the field to more easily relate their own work to the field and more easily understand the scope of IF techniques and methods. Based on strengths and weaknesses of existing definitions, a definition is proposed that is argued to effectively fulfill the requirements that can be put on a definition of IF as a field of research. Although the proposed definition aims to be precise, it does not fully capture the richness and versatility of the IF field. To address that limitation, we highlight some topics to explore the scope of IF, covering the systems perspective of IF and its relation to ma-chine learning, optimization, robot behavior, opinion aggregation, and databases.

- Using stochastic simulations and elasticity analysis, we show that there are inherent differences in the risk of extinction between life histories with different demographies. Which life history is the most vulnerable depends on which vital rate varies. When juvenile survival varies semelparous organisms with delayed reproduction are the most vulnerable ones, while a varying developmental rate puts a greater threat to semelparous organisms with rapid development. Iteroparous organisms are the most vulnerable ones when adult survival varies. Generally, we do not expect to observe organisms in nature having variation in vital rates that produce a high risk of extinction. Given the results here we therefore predict that iteroparous organisms should show low variation in adult survival. Moreover, we predict that semelparous organisms should show low variation in juvenile survival and low variation in developmental rate. The effect of temporal correlation on extinction risk is most pronounced in organisms with semelparous life histories. © 2001 Academic Press.
