A first-line nurse manager's goal-profile.

AIM: The aim of this case study was to acquire understanding concerning the first-line nurse manager's goal-profile, i.e. prioritization of goals in her work as a first-line nurse manager, through use of an action-theoretic and confirmatory theory. BACKGROUND: The first-line nurse manager's pivotal role regarding quality of care and development in relation to on-going changes in the health care sector is stressed by many researchers and the transition from nurse to manager is described as a demanding challenge for the first-line nurse manager. METHODS: The case study described in this paper concerns a first-line nurse manager in an actual working environment in care of older people. Data collection comprised interviews, observations, a job description and policy documents. A hermeneutic interpretation was used for data analysis. RESULTS: The results showed that the first-line nurse manager had three goals in her goal-profile, in the following order of priority: (i) a nurse goal that she had strongly accepted and in which she had excellent control, (ii) an administrator goal that she had accepted and in which she had control, (iii) a leadership goal that she had not accepted and in which she did not have control. Both the administrator and leadership goals were based on her job description, but the nurse goal was a personally chosen goal based on her own self-relation/goal-fulfillment. CONCLUSION: The first-line nurse manager's prioritized self-identity, based on successful realization of goals in her goal-profile, was decisive in the manifestation of her work. RELEVANCE TO CLINICAL PRACTICE: This study contributes to a new understanding of the first-line nurse manager's self-identity related to work in terms of goal acceptance and goal control of prioritized goals. This action-theoretic approach could be a valuable 'key' for understanding leadership (or lack of leadership) in clinical practice.

The socioeconomic gradient in the incidence of stroke: a prospective study in middle-aged women in Sweden.

BACKGROUND AND PURPOSE: A socioeconomic gradient in stroke has been demonstrated in a variety of settings, but mostly in men. Our purpose was to establish whether a socioeconomic gradient in stroke existed in a group of Swedish women and whether this gradient could be explained by established stroke risk factors or psychosocial factors. METHODS: The Women's Lifestyle and Health Cohort Study includes 49 259 women from Sweden aged 30 to 50 years at baseline (1991 to 1992). The women completed an extensive questionnaire and were traced through linkages to national registries until the end of 2002. Among the 47 942 women included in these analyses, there were 200 cases of incident stroke during follow up (121 ischemic stroke, 47 hemorrhagic stroke, and 32 of unknown origin). Statistical analysis was through the Cox proportional hazards model. RESULTS: The risk of stroke was significantly inversely related to years of education completed, our proxy for socioeconomic status (hazard ratio comparing lowest with highest education group=2.1, 95% CI: 1.4 to 2.9, P for trend <0.001). This association was reduced after adjustment for established risk factors, although remaining significant (1.5, 1.0 to 2.2, P for trend=0.04). The gradient was more pronounced for ischemic stroke (2.9, 1.8 to 4.7, P for trend <0.001) than for hemorrhagic stroke (1.4, 0.7 to 2.9, P for trend=0.35). Job strain and social support were unrelated to risk of stroke. Self-rated health was strongly related to risk of stroke mediated by established risk factors. Psychosocial factors did not contribute toward the socioeconomic gradient in stroke. CONCLUSIONS: There was a strong gradient in risk of stroke by years of education, especially for ischemic stroke. Most of the social gradient was explained by established risk factors, particularly smoking and alcohol, but not by psychosocial factors.

The demand control model and circadian saliva cortisol variations in a Swedish population based sample (The PART study).

BACKGROUND: Previous studies of the relationship between job strain and blood or saliva cortisol levels have been small and based on selected occupational groups. Our aim was to examine the association between job strain and saliva cortisol levels in a population-based study in which a number of potential confounders could be adjusted for. METHODS: The material derives from a population-based study in Stockholm on mental health and its potential determinants. Two data collections were performed three years apart with more than 8500 subjects responding to a questionnaire in both waves. In this paper our analyses are based on 529 individuals who held a job, participated in both waves as well as in an interview linked to the second wave. They gave saliva samples at awakening, half an hour later, at lunchtime and before going to bed on a weekday in close connection with the interview. Job control and job demands were assessed from the questionnaire in the second wave. Mixed models were used to analyse the association between the demand control model and saliva cortisol. RESULTS: Women in low strain jobs (high control and low demands) had significantly lower cortisol levels half an hour after awakening than women in high strain (low control and high demands), active (high control and high demands) or passive jobs (low control and low demands). There were no significant differences between the groups during other parts of the day and furthermore there was no difference between the job strain, active and passive groups. For men, no differences were found between demand control groups. CONCLUSION: This population-based study, on a relatively large sample, weakly support the hypothesis that the demand control model is associated with saliva cortisol concentrations.

Predictors of self-rated health: a 12-month prospective study of IT and media workers.

OBJECTIVE: The aim of the present study was to determine health-related risk and salutogenic factors and to use these to construct prediction models for future self-rated health (SRH), i.e. find possible characteristics predicting individuals improving or worsening in SRH over time (0-12 months). METHODS: A prospective study was conducted with measurements (physiological markers and self-ratings) at 0, 6 and 12 months, involving 303 employees (187 men and 116 women, age 23-64) from four information technology and two media companies. RESULTS: There were a multitude of statistically significant cross-sectional correlations (Spearman's Rho) between SRH and other self-ratings as well as physiological markers. Predictors of future SRH were baseline ratings of SRH, self-esteem and social support (logistic regression), and SRH, sleep quality and sense of coherence (linear regression). CONCLUSION: The results of the present study indicate that baseline SRH and other self-ratings are predictive of future SRH. It is cautiously implied that SRH, self-esteem, social support, sleep quality and sense of coherence might be predictors of future SRH and therefore possibly also of various future health outcomes.

Psychosocial determinants of coronary heart disease in middle-aged women: a prospective study in Sweden.

A social gradient in coronary heart disease (CHD) has been documented in a variety of settings, predominantly among men. This study aimed to establish whether a social gradient in CHD existed in a group of Swedish women and whether it could be explained by established coronary risk factors or psychosocial factors. The Women's Lifestyle and Health Cohort Study includes 49,259 women from Sweden aged 30-50 years at baseline (1991-1992), when an extensive questionnaire was completed. There was complete follow-up through linkages to national registries until the end of 2002, during which time 210 cases of incident fatal CHD or nonfatal myocardial infarction occurred. Risk of CHD was significantly inversely related to years of education, the socioeconomic status proxy (hazard ratio comparing the lowest with the highest education group = 3.3, 95% confidence interval: 2.2, 4.7). This association was reduced after adjustment for established coronary risk factors (smoking, body mass index, alcohol consumption, diabetes, hypertension, exercise; hazard ratio = 1.9, 95% confidence interval: 1.3, 2.8). Job strain and social support were weakly related to CHD and did not explain the gradient by years of education. Self-rated health was strongly related to CHD, mediated by established coronary risk factors. Results show a strong gradient in CHD by years of education explained by established coronary risk factors but not by job strain or social support.

Does occupational gender segregation influence the association of effort-reward imbalance with myocardial infarction in the SHEEP study?

The objective of this study was to investigate whether occupational gender segregation moderates the association between job stress in terms of effort-reward imbalance and the risk of myocardial infarction. This analysis was conducted in 1,381 cases and 1,697 referents of the Swedish SHEEP case control study aged 45-70 years. Information on myocardial infarction and biological coronary risk factors (e.g. hypertension, blood lipids) was achieved from clinical screenings. Information on socio-demographic variables, effort-reward imbalance, behavioral coronary risk factors (e.g., smoking), and additional coronary risk factors (e.g., diabetes, family history of coronary heart disease) was derived from well-tested standardized questionnaires. After adjustment for confounders the strongest association between overcommitment (the intrinsic component of effort-reward imbalance) and risk of belonging to the myocardial infarction group was found among women in male-dominated jobs (odds ratio [OR] = 2.71, 95% CI = 1.13-6.52) as compared to the remaining group (OR = 1.52, 95% CI = 1.01-2.31). Moreover, a significant interaction between pronounced overcommitment and male domination in relation to myocardial infarction was observed among women (OR = 2.44, 95% CI = 1.05-5.67). In men, an association between the ratio of effort and reward (the extrinsic component of the model) and risk of myocardial infarction was found for the majority, that is the group not working in women-dominated jobs (OR = 1.39, 95% CI = 1.04-1.86). Despite methodological limitations, this study gives preliminary evidence of a moderating effect of occupational gender segregation on the association of effort-reward imbalance (i.e., the intrinsic model component overcommitment) with acute myocardial infarction risk among women, but not among men.

Pride and confidence at work: potential predictors of occupational health in a hospital setting.

BACKGROUND: This study focuses on determinants of a healthy work environment in two departments in a Swedish university hospital. The study is based on previously conducted longitudinal studies at the hospital (1994-2001), concerning working conditions and health outcomes among health care personnel in conjunction with downsizing processes. Overall, there was a general negative trend in relation to mental health, as well as long-term sick leave during the study period. The two departments chosen for the current study differed from the general hospital trend in that they showed stable health development. The aim of the study was to identify and analyse experiential determinants of healthy working conditions. METHODS: Thematic open-ended interviews were carried out with seventeen managers and key informants, representing different groups of co-workers in the two departments. The interviews were transcribed verbatim and an inductive content analysis was made. RESULTS: In the two studied departments the respondents perceived that it was advantageous to belong to a small department, and to work in cooperation-oriented care. The management approaches described by both managers and co-workers could be interpreted as transformational, due to a strain of visionary, delegating, motivating, confirmative, supportive attitudes and a strongly expressed solution-oriented attitude. The daily work included integrated learning activities. The existing organisational conditions, approaches and attitudes promoted tendencies towards a work climate characterised by trust, team spirit and professionalism. In the description of the themes organisational conditions, approaches and climate, two core determinants, work-pride and confidence, for healthy working conditions were interpreted. Our core determinants augment the well-established concepts: manageability, comprehensiveness and meaningfulness. These favourable conditions seem to function as a buffer against the general negative effects of downsizing observed elsewhere in the hospital, and in the literature. CONCLUSION: Research illuminating health-promoting aspects is rather unusual. This study could be seen as explorative. The themes and core dimensions we found could be used as a basis for further intervention studies in similar health-care settings. The result could also be used in future health promotion studies in larger populations. One of the first steps in such a strategy is to formulate relevant questions, and we consider that this study contributes to this.

Psychophysiological effects of a web-based stress management system: a prospective, randomized controlled intervention study of IT and media workers [ISRCTN54254861].

BACKGROUND: The aim of the present study was to assess possible effects on mental and physical well-being and stress-related biological markers of a web-based health promotion tool. METHODS: A randomized, prospectively controlled study was conducted with before and after measurements, involving 303 employees (187 men and 116 women, age 23-64) from four information technology and two media companies. Half of the participants were offered web-based health promotion and stress management training (intervention) lasting for six months. All other participants constituted the reference group. Different biological markers were measured to detect possible physiological changes. RESULTS: After six months the intervention group had improved statistically significantly compared to the reference group on ratings of ability to manage stress, sleep quality, mental energy, concentration ability and social support. The anabolic hormone dehydroepiandosterone sulphate (DHEA-S) decreased significantly in the reference group as compared to unchanged levels in the intervention group. Neuropeptide Y (NPY) increased significantly in the intervention group compared to the reference group. Chromogranin A (CgA) decreased significantly in the intervention group as compared to the reference group. Tumour necrosis factor alpha (TNFalpha) decreased significantly in the reference group compared to the intervention group. Logistic regression analysis revealed that group (intervention vs. reference) remained a significant factor in five out of nine predictive models. CONCLUSION: The results indicate that an automatic web-based system might have short-term beneficial physiological and psychological effects and thus might be an opportunity in counteracting some clinically relevant and common stress and health issues of today.

Influence of intensive coronary care acoustics on the quality of care and physiological state of patients.

AIM OF THE STUDY: To evaluate the possible role of room acoustics on patients with coronary artery disease and to test the hypothesis that a poor acoustics environment is likely to produce a bad work environment resulting in unwanted sound that could adversely affect the patients. METHODS AND RESULTS: A total of 94 patients admitted to the intensive coronary heart unit at Huddinge University Hospital for evaluation of chest pain were included in the study. Patient groups were recruited during bad and good acoustics, respectively. Acoustics were altered during the study period by changing the ceiling tiles throughout the CCU from sound-reflecting tiles (bad acoustics) to sound-absorbing tiles (good acoustics) of similar appearance. Patients were monitored with regard to blood pressure including pulse amplitude, heart rate and heart rate variability. The patients were asked to fill in a questionnaire about the quality of the care, and a follow-up of rehospitalization and mortality was made at 1 and 3 months, respectively. There were significant differences between good and bad acoustics with regard to pulse amplitude in the acute myocardial infarction and unstable angina pectoris groups, with lower values during the good acoustics period during the night. The incidence of rehospitalization was higher for the bad acoustics group. Patients treated during the good acoustics period considered the staff attitude to be much better than during the bad acoustics period. CONCLUSION: A bad acoustics environment during acute illness may have important detrimental physiological effects on rehabilitation.

Psychosocial factors and respiratory and cardiovascular parameters during psychophysiological stress profiling in working men and women.

The relationship between psychosocial factors and psychophysiological reactions to a situation including stressors and relaxation in a working population was examined. A sample of 115 working men and women aged 26-65 was used. Each participant was examined at baseline, during deep breathing, experimentally induced stress and relaxation. Heart rate, exhalation carbon dioxide, oxygen saturation and blood pressure were monitored. Significant variations across experimental conditions were observed for all physiological variables. There was a pronounced lowering of blood pressure during deep breathing. Women showed significantly more pronounced physiological variation than men. Participants with low education reacted with significantly more systolic blood pressure elevation during the stressful conditions than others. The implication of the results for therapeutic and preventive exercises with deep breathing are discussed.

Saliva cortisol--a new approach in noise research to study stress effects.

Several studies have indicated an association between noise exposure and cardiovascular disease. A noise-induced release of stress hormones has been considered to be a biological pathway of importance in this respect. The described method is of special interest since concentration of cortisol in saliva reflects the concentration of free cortisol in serum and repeated saliva samples can easily be collected. Our objective is to overview the use of saliva cortisol to measure stress in relation to noise as a tool for research on noise-related cardiovascular risk. Previous studies of saliva cortisol in relation to noise exposure are reviewed. In summary, repeated assessments of saliva cortisol seems to be a feasible method to apply in field studies in noise research.

Coping with critical life events and lack of control--the exertion of control.

Coping strategies in relation to unfair treatment or conflicts at work are discussed. 'Covert coping' has been assessed by means of a short questionnaire. Its relationship with cardiovascular risk and sick leave has been examined in an epidemiological study (WOLF) of working men and women in Stockholm. The findings indicate that in men 'covert coping' is associated with elevated cardiovascular risk and prospective long-term sick leave. In women such a coping strategy is related to current sick leave, but not to cardiovascular risk or long-term sick leave. Openness of coping strategies is also discussed in relation to bouts of anger preceding myocardial infarction. Another epidemiological study (SHEEP, ONSET) has shown that severe bouts of anger are reported significantly more often than expected during the hour preceding myocardial infarction. This was not the case in subjects who reported 'open coping patterns', however. Openness of coping strategies is partly determined by the working climate--the higher the decision latitude, the less 'covert' the coping strategies. The results support the idea that dialogue in the work place may be health promoting.

Are trends in work and health conditions interrelated? A study of Swedish hospital employees in the 1990s.

Swedish hospital personnel were followed over an 8-year period, characterized by staff redundancies and restructuring processes. Self-rated and administrative data sets from 1994 to 2001 allowed for studying long-term consequences of organizational instability for staff health and work conditions. The aim was to identify, on a work-unit level, trends in work and health conditions and their interdependence. Regression analysis showed a downward trend in mental health and an upward trend in long-term sick leave. Increasing trends of work demands were accompanied by deteriorating mental health, and decreasing time to plan work showed the strongest association with increasing long-term sick leave. Job satisfaction and support were decreasing. A stable short-term sick leave rate over years related to lack of support.

Assistant nurses in the Swedish healthcare sector during the 1990s: a hard-hit occupational group with a tough job.

AIMS: The aim of the study was to explore hospital-based assistant nurses' experiences of psychosocial "stressors", following a period of substantial layoffs (43%) and ongoing healthcare reorganizations. METHODS: An interview study was carried out with 11 assistant nurses working in the same hospital. The interviews took place in 1997, in connection with the last round of redundancies, and were followed up in 1998 and then in 2001. Interviews were audiotaped and transcribed; the content was then analysed. RESULTS: Two main themes were identified from the women's perceived stressors: (a) a hard-hit occupational group experiencing "energy-consuming adjustments", and a "weak position" at the continuing workplace. Job insecurity meant fear of losing valued work tasks in nursing care (de-skilling). The common feature was the duality in the women's descriptions of feeling qualified in nursing care but being treated like a maid, or having intimate practical knowledge but no formal competence; (b) a tougher but underpaid job including "heavy workload" concurrent with "organizational shortcomings", and "frozen salary trends" with a simultaneous feeling of lacking the power to improve their situation. CONCLUSIONS: Our results underscore the importance of the employer's attention to the remaining workers in connection with downsizing, particularly when the reduction of the workforce has been as dramatic as in this case. It is also important to understand the ongoing dilemma (strain) for the assistant nurses, who are faced with increasing demands for further formal qualifications in hospital care, while maintaining a strong occupational desire to keep their highly valued job working close to the patient.

Dual source support and control at work in relation to poor health.

BACKGROUND AND AIM: Social support and decision authority in relation to health has been examined in extensive research. However, research on the role of different constellations of support sources is conspicuously lacking. The aim of the present study is to describe the health of employees in eight contrasting situations that differ with regard to support from superiors and from workmates and with regard to decision authority. Men and women were studied separately. STUDY SAMPLE AND METHODS: A large sample of Swedish employees (n = 53,371, after exclusion of supervisors) who participated in a national work environment survey was utilized. In addition prospective long-term sick leave data (60 days or more during the 12 months after questionnaire completion) were collected from the national insurance register. RESULTS: Employees who reported below median decision authority had higher prevalence of pains after work and general physical symptoms as well as a higher incidence of long-term sick leave than those with higher decision authority in all subgroups. Those with good support from both workmates and superiors had lower symptom prevalence and long-term sick leave incidence than those with poor support. The groups with either poor support from superiors or from workmates were in an intermediate category with regard to symptom prevalence. The group with good support from superiors but weak support from workmates, however, had as high long-term sick leave incidence as the group with poor support from both superiors and workmates. The patterns were similar for men and women. CONCLUSION: Long-term sick leave was related mainly to poor support from workmates. Prevalence of symptoms, on the other hand, was related to both sources of support and absence of both sources was associated with particularly high prevalence of physical symptoms. This illustrates that it is meaningful to separate the social support sources.

Test performance and self-esteem in relation to experienced stress in Swedish sixth and ninth graders--saliva cortisol levels and psychological reactions to demands.

AIMS: To study relations between test performance, academic self-esteem, self-reported stress and saliva cortisol levels in students exposed to test demands at school. METHODS: 46 randomly selected 6th and 9th graders voluntarily participated in an experimental school test concerning reading and mathematics skills. Cortisol saliva samples were collected at awakening, 30 min later, before test and after test. Perceived stress was registered with a visual analogue scale (VAS). A standardized self-rating questionnaire for measuring self-esteem was administered together with questions about school stress and psychological reactions when exposed to stress during a test. RESULTS: Experienced stress during the school test was correlated to low test performance and to low self-rated evaluation of self-esteem as well as to an increase of saliva cortisol levels during the test. There were also correlations between certain psychological reactions to demands and different cortisol measures. Children who reported that they applied the procedure "I say to myself: I can solve this task" in a school test situation had a lower morning increase of saliva cortisol. Reported use of the procedure "I get worried and will have problems solving other tasks too"--when referring to a school test situation--was correlated to an increase in cortisol levels during the test situation. CONCLUSION: Test performance, academic self-esteem, perceived stress and reactions of the hypothalamus-pituitary-adrenal axis (HPA axis) are highly intertwined. Furthermore, certain school stress psychological reactions to performance demands seem to be related to different cortisol reactions.
