    Women with Neck Pain on Long-Term Sick Leave — Approaches Used in the Return to Work Process: A Qualitative Study2016In: Journal of occupational rehabilitation, ISSN 1053-0487, E-ISSN 1573-3688, 1-14 p.Article in journal (Refereed)
    Abstract [en]

    Purpose There are difficulties in the process of return to work (RTW) from long-term sick leave, both in general and regarding sick leave because of neck pain in particular. Neck pain is difficult to assess, problematic to rehabilitate, and hard to cure; and it is not always easy to decide whether the pain is work-related. The outcome of RTW could be dependent upon individuals’ approaches, defensive or offensive behaviors, and choices related to their self-efficacy. The aim of this study was to identify approaches used in the RTW process among women with neck pain on long-term sick leave from human service organizations. Methods This is a qualitative descriptive study based on grounded theory. A Swedish cohort of 207 women with a history of long-term sick leave with neck pain from human service organizations answered open-ended written questions at 0, 6, and 12 months, and 6 years; and 16 women were interviewed. Results Individuals expressed their coping approaches in terms of fluctuating in work status over time: either as a strategy or as a consequence. Periods of sick leave were interwoven with periods of work. The women were either controlling the interaction or struggling in the interaction with stakeholders. Conclusions Return to work outcomes may be improved if the fluctuating work status over time is taken into account in the design of rehabilitation efforts for women with a history of long-term sick leave and with chronical musculoskeletal conditions.

    Return to work from long-term sick leave: a five-year prospective study of the importance of adjustment latitudes at work and home2014Conference paper (Other academic)
    Abstract [en]

    Background

    Adjustment latitude among employees, i.e. adjusting work to individual’s health capacity, has been associated with successful return to work (RTW) in cross-sectional studies. The aim is to investigate the long-term importance of adjustment latitude at the workplace and at home, as well as attitudes (own and colleagues) for increased work ability (WA), working degree (WD) and health-related quality of life (HRQoL) among female human service workers (HSW) on long-term sick leave in Sweden.

    Methods

    A cohort of female HSW (n=324) on long-term sick leave (>60 day) received a questionnaire at four times (0, 6, 12, 60 months). Prevalence ratios (PR) were used to examine possible relationships between explanatory factors and outcomes. Linear mixed models were used for longitudinal analysis of the repeated measurements of WA Score (0-10), WD (0-100%) and HRQoL (0-100). Analyses were performed with different models; the explanatory variables for each model were adjustment latitude, attitudes towards breaks at work, shared or single household and amount of household work.

    Result

    Having more adjustment latitude at work was associated with both increased WA and RTW compared to having few adjustment latitude opportunities. Adjustments related to working-pace were strongly associated with increased WD (PR 3.29(95%CI=1.71-6.26)), as were adjustments to working-place. Having opportunities to take short breaks at work, and a general acceptance at work to take short breaks was associated with increased WA. At home, a higher responsibility for household work (PR 1.98(95%CI=1.33-2.95)) was related to increased WA and RTW. Individuals with possibilities for adjustment latitude, especially pace and place, at work, and an acceptance to take breaks at work, increased in WA score significantly more over time and had higher WA score compared with individuals not having such opportunities at work. These prospective results were similar for the outcome WD and HRQoL.

    Conclusions

    The results highlight the importance of possibilities for adjustment latitude at work and at home, as well as accepting attitudes to take short breaks to increase WA and RTW among female human service workers previously on long-term sick leave.

    Sleep disturbances predict future sickness absence among individuals with lower back or neck-shoulder pain: A 5-year prospective study2015In: Scandinavian Journal of Public Health, ISSN 1403-4948, E-ISSN 1651-1905, Vol. 43, no 3, 315-323 p.Article in journal (Refereed)
    Abstract [en]

    Background: Musculoskeletal pain is one of the most common causes of sickness absence. Sleep disturbances are often co-occurring with pain, but the relationship between sleep and pain is complex. Little is known about the importance of self-reported sleep, when predicting sickness absence among persons with musculoskeletal pain. This study aims to study the association between self-reported sleep quality and sickness absence 5 years later, among individuals stratified by presence of lower back pain (LBP) and neck and shoulder pain (NSP). Methods: The cohort (n = 2286) in this 5-year prospective study (using data from the MUSIC-Norrtälje study) was stratified by self-reported pain into three groups: no LBP or NSP, solely LBP or NSP, and oncurrent LBP and NSP. Odds ratios (ORs) for the effect of self-reported sleep disturbances at baseline on sickness absence (> 14 consecutive days), 5 years later, were calculated. Results: Within all three pain strata, individuals reporting the most sleep problems showed a significantly higher OR for all-cause sickness absence, 5 years later. The group with the most pronounced sleep problems within the concurrent LBP and NSP stratum had a significantly higher OR (OR 2.00; CI 1.09-3.67) also for long-term sickness absence (> 90days) 5 years later, compared to the group with the best sleep. Conclusions: Sleep disturbances predict sickness absence among individuals regardless of co-existing features of LBP and/or NSP. The clinical evaluation of patients should take possible sleep disturbances into account in the planning of treatments.

    A Novel-Data Mining Platform to Monitor the Outcomes of Erlontinib (Tarceva) using Social Media2014In: XIII Mediterranean Conference on Medical and Biological Engineering and Computing 2013, Springer, 2014, 1394-1397 p.Conference paper (Refereed)
    Abstract [en]

    A novel data-mining method was developed to gauge the experiences of the oncology drug Tarceva. Self-organizing maps were used to analyze forum posts numerically to infer user opinion of drug Tarceva. The result is a word list compilation correlating positive and negative word cluster groups and a web of influential users on Tarceva. The implica-tions could open new research avenues into rapid data collec-tion, feedback, and analysis that would enable improved solu-tions for public health.

    Assessing Antidepressants Using Intelligent Data Monitoring and Mining of Online Fora2016In: IEEE journal of biomedical and health informatics, ISSN 2168-2194, E-ISSN 2168-2208, Vol. 20, no 4, 977-986 p.Article in journal (Refereed)
    Abstract [en]

    Depression is a global health concern. Social networks allow the affected population to share their experiences. These experiences, when mined, extracted, and analyzed, can be converted into either warnings to recall drugs (dangerous side effects), or service improvement (interventions, treatment options) based on observations derived from user behavior in depression-related social networks. Our aim was to develop a weighted network model to represent user activity on social health networks. This enabled us to accurately represent user interactions by relying on the data's semantic content. Our three-step method uses the weighted network model to represent user's activity, and network clustering and module analysis to characterize user interactions and extract further knowledge from user's posts. The network's topological properties reflect user activity such as posts' general topic as well as timing, while weighted edges reflect the posts semantic content and similarities among posts. The result, a synthesis from word data frequency, statistical analysis of module content, and the modeled health network's properties, has allowed us to gain insight into consumer sentiment of antidepressants. This approach will allow all parties to participate in improving future health solutions of patients suffering from depression.

    Mining Social Media Big Data for Health2015In: IEEE PulseArticle, review/survey (Refereed)
    Abstract [en]

    Advances in information technology (IT) and big data are affecting nearly every facet of the public and private sectors. Social media platforms are one example of such advances: its nature allows users to connect, collaborate, and debate on any topic with comparative ease. The result is a hefty volume of user-generated content that, if properly mined and analyzed, could help the public and private health care sectors improve the quality of their products and services while reducing costs. The users of these platforms are the key to these improvements, as their valuable feedback will help improve health solutions.

    The importance of healthcare managers’ organizational preconditions and support resources for their appraisal of planned change and its outcomes2017In: Journal of Hospital Administration, ISSN 1927-6990, E-ISSN 1927-7008, Vol. 6, no 1Article in journal (Refereed)
    Abstract [en]

    Background: Healthcare managers are expected to lead and manage planned organizational change intended to improve healthcare process quality. However, their complex working conditions offer limited decision control, and healthcare managers often feel ill prepared and inadequately supported to perform their duties. Healthcare managers have previously described their need for organizational support, but we lack knowledge of the preconditions and resources that help managers implement planned change.Methods: This prospective cohort study examined healthcare managers at three Swedish hospitals implementing lean production and two Swedish hospitals implementing their own improvement model. Questionnaire data from 2012, 2103, and 2014 were used in following up. We used t-tests and a linear mixed model design in analysing the data.Results: Healthcare managers who perceived strong support from managers, employees, colleagues, and the organization and managers with the longest managerial experience had the least negative appraisal of change. Managers who perceived strong support from employees, management, and the organizational structure perceived higher levels of healthcare process quality.Conclusions: Long managerial experience and strong support from managers, employees, and the organization are important formanagers’ appraisal of, work on, and successful implementation of planned change. Top management must therefore ensure that the healthcare managers have sufficient managerial experience and support before they delegate to them the responsibility to implement planned change.

    Health care managers' views on and approaches to implementing models for improving care processes2016In: Journal of Nursing Management, ISSN 0966-0429, E-ISSN 1365-2834, Vol. 24, no 2Article in journal (Refereed)
    Abstract [en]

    Aim: To develop a deeper understanding of health-care managers' views on and approaches to the implementation of models for improving care processes. Background: In health care, there are difficulties in implementing models for improving care processes that have been decided on by upper management. Leadership approaches to this implementation can affect the outcome. Method: In-depth interviews with first- and second-line managers in Swedish hospitals were conducted and analysed using grounded theory. Results: 'Coaching for participation' emerged as a central theme for managers in handling top-down initiated process development. The vertical approach in this coaching addresses how managers attempt to sustain unit integrity through adapting and translating orders from top management. The horizontal approach in the coaching refers to managers' strategies for motivating and engaging their employees in implementation work. Conclusion and implications for nursing management: Implementation models for improving care processes require a coaching leadership built on close manager-employee interaction, mindfulness regarding the pace of change at the unit level, managers with the competence to share responsibility with their teams and engaged employees with the competence to share responsibility for improving the care processes, and organisational structures that support process-oriented work. Implications for nursing management are the importance of giving nurse managers knowledge of change management.

    Abstract [en]

    Företagshälsovård, fhv, är en viktig aktör i välfärdssamhället. Den ska bidra både till att förebygga ohälsa och främja hälsa samt till att ska pagoda och säkra arbetsplatser där de anställda inte riskerar att skadas eller bli sjuka. Omvärldens förväntningar är höga. För att uppfylla dem krävs att fhv har en bred kompetens och att arbetet bygger på samarbete både mellan olika kompetenser inom den egna verksamheten och med de företag och organisationer som fhv arbetar för.

    Abstract [en]

    Många företag med mindre än 50 anställda har någon form av avtal med FHV och de flesta är nöjda. Deras anställda står dock bara för en liten andel av alla arbetstagare som har tillgång till fhv. En stor del av småföretagen utnyttjar inte FHV:s breda kompetens utan anlitar dem främst för hälsoundersökningar. Det betyder att det finns en stor utvecklingspotential om man kan få de mindre företagen att efterfråga fler tjänster.

    Risk assessment tools for small enterprises: evaluation of uptake and effect2009In: USE 2009: Programme and abstract book, 2009, 118-118 p.Conference paper (Other academic)
    Abstract [en]

    Background: Risk assessment is a core component in the management of the working environment. Risk assessment helps identify and prioritize risks and reduce risks through implementation of control measures. Aim: To evaluate how tools for risk assessment are used by small enterprises and what the result is from using the tools. Method: Randomly selected small enterprises in printing and electroplating industry were contacted and asked to participate in an evaluation of tools for chemical risk assessment developed to suit small enterprises. An initial interview was made with the enterprises accepting to participate in the testing, aiming at surveying how they use to assess chemical risks. The enterprises were provided with one out of six tools. Ten enterprises in each sector were asked to test each tool, adding up to 20 enterprises testing each tool. After three and six months the enterprise was contacted. If they had tested the tool, a new interview was made, exploring their opinion on the tool and their experiences from using it. Enterprises not having tested the tools were also interviewed about the reasons why they did not use the tool they were provided. In enterprises having used the tools, an expert risk assessment was made and compared to the risk assessment of the enterprise in order to evaluate the quality of the risk assessment tool and the enterprise's use of it. Result: More than 60 % of the enterprises accepted to test the tools, reflecting an interest and concern for chemical risks in their work environment. The follow-up interviews are currently conducted and will be finished during April 2009. The results show how risk assessment works in practice in small enterprises. The study has revealed several problems with different tools and some unexpected results. One example is that several enterprises have concluded that they are content with their old method for risk assessment, which was using safety data sheets, reflecting a profound lack of understanding of what risk assessment is about. Results from the evaluation will be presented, showing how small enterprises perceive the different kinds of tools tested and what the outcomes in terms of quality are of the tested tools. The results will be discussed in relation to the enterprises and their previous experience of and knowledge about risk assessment.

    Synergonomi och ögonbesvär hos personal på ögonsjukhus.2012Conference paper (Other academic)
    Abstract [sv]

    Ögonläkare, ögonsjuksköterskor, optiker och annan personal på ögonsjukhus arbetar ofta med synkrävande arbetsuppgifter i dämpad belysning eller helt utan allmänbelysning. Inför den planerade byggnationen av ett nytt ögonsjukhus i Stockholm ca år 2018 gjordes en enkätstudie för att kartlägga ögonbesvär och trötthet hos personalen på S:t Eriks Ögonsjukhus. Studien som är ett multidisciplinärt samarbetsprojekt mellan S:t Erik, Karolinska Institutet och Kungliga Tekniska Högskolan, syftar till att optimera belysning, dagsljusinsläpp och ljusmiljö vid det nya ögonsjukhuset.

    Totalt 265 anställda på S:t Eriks Ögonsjukhus samt 60 röntgenläkare och 45 barnläkare, varav de senare två  utgjorde jämförelsegrupper, inviterades till  studien.  Enkäten som distribuerades baserades på synergonomienkäter av Knave och Hemphälä och bestod av 31 validerade frågor om subjektiva ögonbesvär, nuvarande belysning, tillgång till dagsljus och välbefinnande. Ögonbesvären räknades om till ett gruppmedelvärde (ögonbesvärsindex) med avseende på svårighetsgrad och frekvens. Studien är godkänd av Etikprövningsnämnden. 

    Nittiosex av 265 (33%) anställda på S:t Eriks Ögonsjukhus hade t o m juni 2012 besvarat enkäten tillsammans med 23 röntgenläkare (38%) och 14 barnläkare (31%). Ögonbesvär som torrhets- och gruskänsla var vanligt förekommande hos alla yrkesgrupper på ögonsjukhuset och generellt vanligare hos kvinnor. Då samtliga grupper jämfördes med avseende på ögonbesvärsindex var skillnaden mellan män och kvinnor statistiskt säkerställd (p<0,05). Röntgenläkarna rapporterade högst ögonbesvärsindex och barnläkarna lägst, skillnaden mellan dessa yrkesgrupper var signifikant (p<0,05). Ögonpersonal och röntgenläkare som rapporterade att de ofta arbetade i mörker, associerade detta med  ökad trötthet i högre grad än  med barnläkarna (p<0,05).

    Ögonbesvär var vanliga hos ögonpersonalen inkluderade i studien. Den grupp som arbetade mest i mörker hade mer ögonbesvär än den grupp som arbetade minst i mörker. Kvinnor hade mer ögonbesvär än män. Arbete i mörker ökade den subjektiva känslan av trötthet . Optimala ljusförhållanden och bra synergonomi bör ges hög prioritet vid planering av ett nytt ögonsjukhus.

    Visual ergonomics and eye strain in eye careprofessionals2012In: NES2012 Proceedings: Ergonomics for sustainability and growth / [ed] Ann-Beth Antonsson, Göran M Hägg, 2012Conference paper (Other academic)
    Abstract [en]

    Eye care professionals spend many hours a day in darkness performing visually demanding tasks. A new eye hospital will be built in Stockholm 2018. The current lighting, logistics, and working conditions are analysed in a multidisciplinary project aiming to optimise settings in the new hospital. The main purpose of the present project was to study visual ergonomics and current eye strain in employees at an eye hospital. Ninety-six employees answered a validated questionnaire regarding their experiences of light, visual ergonomics and eye strain problems. Twenty-three radiologists and 14 paediatricians at a university hospital were used as comparison groups. Eye strain was common in all departments at the hospital but was significantly more common only among radiologists compared to paediatricians. Overall, women experienced significantly more eye strain than men.

    Incidence of traumatic peripheral nerve injuries and amputations in Sweden between 1998 and 20062008In: Neuroepidemiology, ISSN 0251-5350, E-ISSN 1423-0208Article in journal (Refereed)
    Abstract [en]

    Background: To define the epidemiological pattern of nerve injuries and traumatic amputations in Sweden, 1998-2006, and investigate possible targets for emerging neural engineering and neuroprosthetic technologies.

    Methods: The Swedish Hospital Discharge Register was used as basis of information, including data from all public in-patient care, excluding out-patient data. ICD-10 codes were screened for nerve injuries and traumatic amputations of high incidence or in-patient care time. Selected codes, causing factors, age and gender distribution were discussed in detail, and potential targets for tailored solutions were identified.

    Results: Incidence rate was determined to 13.9 for nerve injuries and 5.21 for amputations per 100 000 person-yrs. The majority of injuries occurred at wrist and hand level although it could be concluded that these are often minor injuries requiring less than a week of hospitalization. The single most care consuming nerve injury was brachial plexus injury constituting, in average, 68 injuries and 960 hospital days annually. When minor amputations of fingers and toes were disregarded, most frequent site of amputation was between knee and ankle (24 patients / year).

    Conclusions: Based on analysis of incidence and care time, we find that brachial plexus injuries and lower leg amputations should be primary targets of these new technologies.

    Exploring communication processes in workplace meetings: A mixed methods study in a Swedish healthcare organization2016In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270, Vol. 54, no 3, 533-541 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: An efficient team and a good organizational climate not only improve employee health but also the health and safety of the patients. Building up trust, a good organizational climate and a healthy workplace requires effective communication processes. In Sweden, workplace meetings as settings for communication processes are regulated by a collective labor agreement. However, little is known about how these meetings are organized in which communication processes can be strengthened. OBJECTIVE: The aim of this study was to explore communication processes during workplace meetings in a Swedish healthcare organization. METHODS: A qualitatively driven, mixed methods design was used with data collected by observations, interviews, focus group interviews and mirroring feedback seminars. Data were analyzed using descriptive statistics and conventional content analysis. RESULTS: The communication flow and the organization of the observed meetings varied in terms of physical setting, frequency, time allocated and duration. The topics for the workplace meetings were mainly functional with a focus on clinical processes. Overall, the meetings were viewed not only as an opportunity to communicate information top down but also a means by which employees could influence decision-making and development at the workplace. CONCLUSIONS: Workplace meetings have very distinct health-promoting value. It emerged that information and the opportunity to influence decisions related to workplace development are important to the workers. These aspects also affect the outcome of the care provided.

    Exploring the usability of a videophone mock-up for persons with dementia and their significant others2014In: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 14, 49- p.Article in journal (Refereed)
    Abstract [en]

    Background: Persons with dementia might have considerable difficulties in using an ordinary telephone. Being able to use the telephone can be very important in order to maintain their social network, getting stimulation and for reaching help when needed. Therefore, persons with dementia might need an easy-to-use videophone to prevent social isolation and to feel safe and independent. This study reports the evaluation of the usability of a touch-screen videophone mock-up for persons with dementia and their significant others. Methods: Four persons with dementia and their significant others tested the videophone mock-up at a living laboratory. In order to gain knowledge of the participants' with dementia ability to use their own computers and telephones, interviews and observations were conducted. Results: Overall, the participants had a very positive attitude towards the videophone. The participants with dementia perceived that it was useful, enjoyable and easy to use, although they initially had difficulties in understanding how to handle some functions, thus indicating that the design needs to be further developed to be more intuitive. Conclusions: The findings suggest that the videophone has the potential to enable telephone calls without assistance and add quality in communication.

    Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud?: Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator2012Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation. The purpose of thisstudy was to investigate whether nickel or cobalt can be found on computersurfaces and if nickel and cobalt can be released from surfaces that are incontact with skin, during work with laptops. Are there any variations betweendifferent models or different brands of laptops (two years old or less) andwhat levels of nickel and cobalt are released from different surfaces on a specificHP computer, that gave positive results for nickel and cobalt in the spot- tests? Methodand materials: In this study 30laptops (7 Hewlett Packard (HP), 18 Dell, 3 Sony Vaio, 1Fujitsu and 1 Macbook), weretested by using DMG-test and cobalt spot-test. To measure the release of nickeland cobalt on one specific laptop (HP2560p), the standard method EN1811 and amodified version of the method, were used. Results: Laptopsof different models and manufacturers were tested for nickel by using theDMG-test. The test turned out positive for all tested laptops from HP and 4 of18 of the laptops from Dell. For cobalt, onlyone laptop (HP) of the total 30 computers, gave a positive result. The resultsfrom the release test of a specific laptop, was lower than the limit thresholdvalue within REACH (0.5µg/cm2/week). The highest amounts of nickel,0.1μg/cm2/week, were measured for the computer components thatwere derived from the palm rest. All the cobalt levels, except one, were belowthe detection limit for the analysis. Conclusions: Our study indicatesthat laptops are a potential source for nickel deposition onto skin. In this study, computers from five differentmanufacturers have been tested, and it turned out that the tested models from HPand Dell released nickel. Cobalt was only released in very low concentrations,at a level near the LOD for the analysis.

    Development of evidence-based practice in occupational health services in Sweden: a 3-year follow-up of attitudes, barriers and facilitators2017In: International Archives of Occupational and Environmental Health, ISSN 0340-0131, E-ISSN 1432-1246, Vol. 90, no 4, 335-348 p.Article in journal (Refereed)
    Abstract [en]

    The Swedish government initiated an investigation of how to secure and develop the competence of the occupational health services. The primary aim of the present study was to investigate whether the development of evidence-based practice (EBP) in the Swedish occupational health services in relation to attitudes, knowledge and use improved during the first 3 years of the government's initiative. The study has a mixed methods design combining questionnaires and interviews with data collection at baseline and at 3-year follow-up. The response rate was 66% at baseline and 63% at follow-up. The results show that practitioners' knowledge of EBP was moderate at baseline and improved at follow-up (p = 0.002; 95% CI 0.01; 0.21). Practitioners experienced lower levels of organizational and managerial support for EBP at follow-up (p < 0.001; 95% CI 0.18; 0.38). The results revealed that managers viewed responsibility for implementing EBP as a matter for individual practitioners rather than as an organizational issue. Occupational health service managers and practitioners are generally positive to EBP. However, the findings emphasize the need to educate managers in how to support EBP at the organizational level by creating an infrastructure for EBP in the OHS.

    Being a pedestrian with dementia: A qualitative study using photo documentation and focus group interviews2016In: Dementia, ISSN 1471-3012, E-ISSN 1741-2684, Vol. 15, no 5, 1124-1140 p.Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to identify problematic situations in using zebra crossings. They were identified from photo documentations comprising film sequences and the perspectives of people with dementia. The aim was also to identify how they would understand, interpret and act in these problematic situations based on their previous experiences and linked to the film sequences. A qualitative grounded theory approach was used. Film sequences from five zebra crossings were analysed. The same film sequences were used as triggers in two focus group interviews with persons with dementia. Individual interviews with three informants were also performed. The core category, the hazard of meeting unfolding problematic traffic situations when only one layer at a time can be kept in focus, showed how a problematic situation as a whole consisted of different layers of problematic situations. The first category, adding layers of problematic traffic situations to each other, was characterized by the informants' creation of a problematic situation as a whole. The different layers were described in the subcategories of layout of streets and zebra crossings, weather conditions, vehicles and crowding of pedestrians. The second category, actions used to meet different layers of problematic traffic situations, was characterized by avoiding problematic situations, using traffic lights as reminders and security precautions, following the flow at the zebra crossing and being cautious pedestrians. In conclusion, as community-dwelling people with dementia commonly are pedestrians, it is important that health care professionals and caregivers take their experiences and management of problematic traffic situations into account when providing support.

    Accessibility in public space as perceived by people with Alzheimer´s disease2011In: Dementia, ISSN 1471-3012, E-ISSN 1741-2684, no aug 11Article in journal (Refereed)
    Abstract [en]

    Most people with dementia remain living at home as long as possible after being diagnosed, and hence their lives also include activities in the public space. The aim of this study was to illuminate experiences of accessibility in public space in people with Alzheimer’s disease. A qualitative grounded theory approach with repeated in-depth interviews was used. The core category, accessibility as a constantly changing experience, was characterized by changes in the relationship between informants and public space. Changes in the relationship took place in activities and use of place and related to familiarity and comfort, individual motives and interests, and planning and protecting. Other changes occurred in places and problematic situations related to everyday technologies, crowded places with high tempo and noise, and change of landmarks. These changes reduced feelings of accessibility and increased difficulties in carrying out activities in public space. These findings may be helpful when providing support, and supporting community living.

    Comparing effects in regular practice of e-communication and web-based self-management support among breast cancer patients: Preliminary results from a randomized controlled trial2014In: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 16, no 12, e295Article in journal (Refereed)
    Abstract [en]

    Background: While Web-based interventions have been shown to assist a wide range of patients successfully in managing their illness, few studies have examined the relative contribution of different Web-based components to improve outcomes. Further efficacy trials are needed to test the effects of Web support when offered as a part of routine care. Objective: Our aim was to compare in regular care the effects of (1) an Internet-based patient provider communication service (IPPC), (2) WebChoice, a Web-based illness management system for breast cancer patients (IPPC included), and (3) usual care on symptom distress, anxiety, depression, (primary outcomes), and self-efficacy (secondary outcome). This study reports preliminary findings from 6 months' follow-up data in a 12-month trial. Methods: We recruited 167 patients recently diagnosed with breast cancer and undergoing treatment from three Norwegian hospitals. The nurse-administered IPPC allowed patients to send secure e-messages to and receive e-messages from health care personnel at the hospital where they were treated. In addition to the IPPC, WebChoice contains components for symptom monitoring, tailored information and self-management support, a diary, and communication with other patients. A total of 20 care providers (11 nurses, 6 physicians, and 3 social workers) were trained to answer questions from patients. Outcomes were measured with questionnaires at study entry and at study months 2, 4, and 6. Linear mixed models for repeated measures were fitted to compare effects on outcomes over time. Results: Patients were randomly assigned to the WebChoice group (n=64), the IPPC group (n=45), or the usual care group (n=58). Response rates to questionnaires were 73.7% (123/167) at 2 months, 65.9 (110/167) at 4 months, and 62.3% (104/167) at 6 months. Attrition was similar in all study groups. Among those with access to WebChoice, 64% (41/64) logged on more than once and 39% (25/64) sent e-messages to care providers. In the IPPC group, 40% (18/45) sent e-messages. Linear mixed models analyses revealed that the WebChoice group reported significantly lower symptom distress (mean difference 0.16, 95% CI 0.06-0.25, P=.001), anxiety (mean difference 0.79, 95% CI 0.09-1.49, P=.03), and depression (mean difference 0.79, 95% CI 0.09-1.49, P=.03) compared with the usual care group. The IPPC group reported significant lower depression scores compared with the usual care group (mean difference 0.69, 95% CI 0.05-1.32, P=.03), but no differences were observed for symptom distress or anxiety. No significant differences in self-efficacy were found among the study groups. Conclusions: In spite of practice variations and moderate use of the interventions, our results suggest that offering Web support as part of regular care can be a powerful tool to help patients manage their illness. Our finding that a nurse-administered IPPC alone can significantly reduce depression is particularly promising. However, the multicomponent intervention WebChoice had additional positive effects.

    How user characteristics affect use patterns in web-based illness management support for patients with breast and prostate cancer.2013In: Journal of medical Internet research, ISSN 1438-8871, Vol. 15, no 3, e34- p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Frequently eHealth applications are not used as intended and they have high attrition rates; therefore, a better understanding of patients' need for support is warranted. Specifically, more research is needed to identify which system components target different patient groups and under what conditions.

    OBJECTIVE: To explore user characteristics associated with the use of different system components of a Web-based illness management support system for cancer patients (WebChoice).

    METHODS: For this secondary post hoc analysis of a large randomized controlled trial (RCT), in which WebChoice was tested among 325 breast cancer and prostate cancer patients who were followed with repeated measures for 1 year, usage patterns of 162 cancer patients in the intervention arm with access to WebChoice were extracted from the user log. Logistic regression was performed to identify patterns of associations between system use and patient characteristics. Latent class analyses (LCA) were performed to identify associations among the use of different system components and levels of social support, symptom distress, depression, self-efficacy, and health-related quality of life.

    RESULTS: Approximately two-thirds (103/162, 63.6%) of the patients logged on to WebChoice more than once, and were defined as users. A high level of computer experience (odds ratio [OR] 3.77, 95% CI 1.20-11.91) and not having other illnesses in addition to cancer (OR 2.10, 95% CI 1.02-4.34) increased the overall probability of using WebChoice. LCA showed that both men with prostate cancer and women with breast cancer who had low scores on social support accompanied with high levels of symptom distress and high levels of depression were more likely to use the e-message component. For men with prostate cancer, these variables were also associated with high use of the self-management advice component. We found important differences between men with prostate cancer and women with breast cancer when associations between WebChoice use and each user characteristic were analyzed separately. High use of all components was associated with low levels of social support among women with breast cancer, but not among men with prostate cancer. High use of e-messages, advice, and the discussion forum were associated with high levels of depression among women with breast cancer, but not among men with prostate cancer. For men with prostate cancer (but not women with breast cancer), high use of symptom assessments, advice, and the discussion forum were associated with high levels of symptom distress. However, it is unclear whether these findings can be attributed to differences related to diagnosis, gender, or both.

    CONCLUSIONS: This study provides evidence that different user characteristics are associated with different use patterns. Such information is crucial to target Web-based support systems to different patient groups. LCA is a useful technique to identify subgroups of users. In our study, e-messages and self-management advice were highly used components for patients who had low levels of social support and high illness burden, suggesting that patients with these characteristics may find such tools particularly useful.

    Trunk muscle activation at the initiation and braking of bilateral shoulder flexion movements of different amplitudes2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 11, e0141777Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to investigate if trunk muscle activation patterns during rapid bilateral shoulder flexions are affected by movement amplitude. Eleven healthy males performed shoulder flexion movements starting from a position with arms along sides (0°) to either 45°, 90° or 180°. EMG was measured bilaterally from transversus abdominis (TrA), obliquus internus (OI) with intra-muscular electrodes, and from rectus abdominis (RA), erector spinae (ES) and deltoideus with surface electrodes. 3D kinematics was recorded and inverse dynamics was used to calculate the reactive linear forces and torque about the shoulders and the linear and angular impulses. The sequencing of trunk muscle onsets at the initiation of arm movements was the same across movement amplitudes with ES as the first muscle activated, followed by TrA, RA and OI. All arm movements induced a flexion angular impulse about the shoulders during acceleration that was reversed during deceleration. Increased movement amplitude led to shortened onset latencies of the abdominal muscles and increased level of activation in TrA and ES. The activation magnitude of TrA was similar in acceleration and deceleration where the other muscles were specific to acceleration or deceleration. The findings show that arm movements need to be standardized when used as a method to evaluate trunk muscle activation patterns and that inclusion of the deceleration of the arms in the analysis allow the study of the relationship between trunk muscle activation and direction of perturbing torque during one and the same arm movement © 2015 Eriksson Crommert et al.

    Effects of prolonged hypoxia and bed rest on appetite and appetite-related hormones2016In: Appetite, ISSN 0195-6663, E-ISSN 1095-8304, Vol. 107, 28-37 p.Article in journal (Refereed)
    Abstract [en]

    Environmental hypoxia and inactivity have both been shown to modulate appetite. To elucidate the independent and combined effects of hypoxia and bed rest-induced inactivity on appetite-related hormones and subjective appetite, eleven healthy, non-obese males underwent three experimental interventions in a cross-over and randomized fashion: 1) Hypoxic confinement combined with daily moderate-intensity exercise (HAMB, FiO2 = 0.141 ± 0.004; PiO2 = 90.0 ± 0.4 mmHg) 2) Bed rest in normoxia (NBR, FiO2 = 0.209; PiO2 = 133.1 ± 0.3 mmHg) and 3) Bed rest in hypoxia (HBR, FiO2 = 0.141 ± 0.004; PiO2 = 90.0 ± 0.4 mmHg). A mixed-meal tolerance test (MTT), followed by an ad libitum meal were performed before (Pre) and after 16-days (Post) of each intervention. Composite satiety scores (CSS) during the MTT were calculated from visual analogue scores, while fasting and postprandial concentrations of total ghrelin, peptide YY (PYY), glucagon-like peptide-1 (GLP-1) and leptin were quantified from arterialized-venous samples. Postprandial CSS were significantly lower at Post compared to Pre in NBR only (P &lt; 0.05) with no differences observed in ad libitum meal intakes. Postprandial concentrations and incremental area under the curve (AUC) for total ghrelin and PYY were unchanged following all interventions. Postprandial GLP-1 concentrations were only reduced at Post following HBR (P &lt; 0.05) with resulting AUC changes being significantly lower compared to HAMB (P &lt; 0.01). Fasting leptin was reduced following HAMB (P &lt; 0.05) with no changes observed following NBR and HBR. These findings suggest that independently, 16-day of simulated altitude exposure (∼4000 m) and bed rest-induced inactivity do not significantly alter subjective appetite or ad libitum intakes. The measured appetite-related hormones following both HAMB and HBR point to a situation of hypoxia-induced appetite stimulation, although this did not reflect in higher ad libitum intakes. Clinical Trial Registration Number: NCT02293772.

    Whole body and regional body composition changes following 10-day hypoxic confinement and unloading-inactivity2014In: Applied Physiology, Nutrition and Metabolism, ISSN 1715-5312, E-ISSN 1715-5320, Vol. 39, no 3, 386-395 p.Article in journal (Refereed)
    Abstract [en]

    Future planetary habitats will expose inhabitants to both reduced gravity and hypoxia. This study investigated the effects of short-term unloading and normobaric hypoxia on whole body and regional body composition (BC). Eleven healthy, recreationally active, male participants with a mean (SD) age of 24 (2) years and body mass index of 22.4 (3.2) kg.m(-2) completed the following 3 10-day campaigns in a randomised, cross-over designed protocol: (i) hypoxic ambulatory confinement (HAMB; FIO2 = 0.147 (0.008); PIO2 = 93.8 (0.9) mm Hg), (ii) hypoxic bed rest (HBR; FIO2 = 0.147 (0.008); PIO2 = 93.8 (0.9) mm Hg), and (iii) normoxic bed rest (NBR; FIO2 = 0.209; PIO2 = 133.5 (0.7) mmHg). Nutritional requirements were individually precalculated and the actual intake was monitored throughout the study protocol. Body mass, whole body, and regional BC were assessed before and after the campaigns using dual-energy X-ray absorptiometry. The calculated daily targeted energy intake values were 2071 (170) kcal for HBR and NBR and 2417 (200) kcal for HAMB. In both HBR and NBR campaigns the actual energy intake was within the targeted level, whereas in the HAMB the intake was lower than targeted (-8%, p < 0.05). Body mass significantly decreased in all 3 campaigns (-2.1%, -2.8%, and -2.0% for HAMB, HBR, and NBR, respectively; p < 0.05), secondary to a significant decrease in lean mass (-3.8%, -3.8%, -4.3% for HAMB, HBR, and NBR, respectively; p < 0.05) along with a slight, albeit not significant, increase in fat mass. The same trend was observed in the regional BC regardless of the region and the campaign. These results demonstrate that, hypoxia per se, does not seem to alter whole body and regional BC during short-term bed rest.

    Exercise Training during Normobaric Hypoxic Confinement Does Not Alter Hormonal Appetite Regulation2014In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 9, no 6, e98874- p.Article in journal (Refereed)
    Abstract [en]

    Background: Both exposure to hypoxia and exercise training have the potential to modulate appetite and induce beneficial metabolic adaptations. The purpose of this study was to determine whether daily moderate exercise training performed during a 10-day exposure to normobaric hypoxia alters hormonal appetite regulation and augments metabolic health. Methods: Fourteen healthy, male participants underwent a 10-day hypoxic confinement at,4000 m simulated altitude (FIO2 = 0.139 +/- 0.003%) either combined with daily moderate intensity exercise (Exercise group; N = 8, Age = 25.8 +/- 2.4 yrs, BMI = 22.9 +/- 1.2 kg.m(-2)) or without any exercise (Sedentary group; N = 6 Age = 24.8 +/- 3.1 yrs, BMI = 22.3 +/- 2.5 kg.m(-2)). A meal tolerance test was performed before (Pre) and after the confinement (Post) to quantify fasting and postprandial concentrations of selected appetite-related hormones and metabolic risk markers. C-13-Glucose was dissolved in the test meal and (CO2)-C-13 determined in breath samples. Perceived appetite ratings were obtained throughout the meal tolerance tests. Results: While body mass decreased in both groups (-1.4 kg; p = 0.01) following the confinement, whole body fat mass was only reduced in the Exercise group (-1.5 kg; p = 0.01). At Post, postprandial serum insulin was reduced in the Sedentary group (-49%; p = 0.01) and postprandial plasma glucose in the Exercise group (-19%; p = 0.03). Fasting serum total cholesterol levels were reduced (-12%; p = 0.01) at Post in the Exercise group only, secondary to low-density lipoprotein cholesterol reduction (-16%; p = 0.01). No differences between groups or testing periods were noted in fasting and/or postprandial concentrations of total ghrelin, peptide YY, and glucagon-like peptide-1, leptin, adiponectin, expired (CO2)-C-13 as well as perceived appetite ratings (p>0.05). Conclusion: These findings suggest that performing daily moderate intensity exercise training during continuous hypoxic exposure does not alter hormonal appetite regulation but can improve the lipid profile in healthy young males.

    Hur kan stödresurser understödja hållbart ledarskap bland chefer i vården?2013In: Socialmedicinsk Tidskrift, ISSN 0037-833X, Vol. 90, no 6Article in journal (Refereed)
    Abstract [sv]

    Chefer kan ha stor betydelse för anställdas hälsa, stress, engagemang i arbetet och prestation. Få tidigare studier har undersökt vilket stöd chefer behöver för ett hållbart och bra ledarskap. Artikeln presenterar resultat från en prospektiv studie om betydelsen av chefers stödresurser för hållbart ledarskap. I studien, som är en del av Chefios-projektet, ingår chefer i kommunal vård och omsorg (n=344). Data från enkätstudier med instrumentet ”Gothenburg Manager Stress Inventory” har analyserats. Resultatet visar att ett stödjande privatliv och en personlig inställning till chefsuppdrag har stor betydelse för chefers hållbarhet över tid. Chefens kontrollspann och erfarenhet som chef påverkade betydelsen av stödresurser. För chefer med kortare chefserfarenhet eller fler underställda (>30) har även stöd från ledning, chefskollegor och externt stöd betydelse.

    Health-Promoting Managerial Work: A Theoretical Framework for a Leadership Program that Supports Knowledge and Capability to Craft Sustainable Work Practices in Daily Practice and During Organizational Change2017In: Societies, ISSN 1090-9389, E-ISSN 2075-4698, Vol. 7, no 2, 12Article in journal (Refereed)
    Abstract [en]

    The aim of this article is to describe a theoretical framework, i.e., theoretical underpinnings and pedagogical principles, for leadership programs that support managers' evidence-based knowledge of health-promoting psychosocial work conditions, as well as their capability to apply, adapt, and craft sustainable managerial work practices. First, the theoretical framing is introduced, i.e., a system theory that integrates key work conditions with a practical perspective on managerial work and organization. Second, pedagogical principles and measures for leaders' training in integrated handling across system levels are described. Last, we present summarized results from an intervention study applying the theoretical framework and pedagogical principles. The complexity of interactions among different factors in a work system, and the variety in possible implementation approaches, presents challenges for the capability of managers to craft sustainable and health-promoting conditions, as well as the evaluation of the program components. Nevertheless, the evaluation reveals the strength of the program, in providing holistic and context-sensitive approaches for how to train and apply an integrative approach for improving the work environment.
