Symptoms and care seeking behaviour during myocardial infarction in patients with diabetes
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: In Myocardial infarction (MI) it is well established that timely diagnosis and treatment may reduce mortality and improve the prognosis. Therefore it is important that patients with MI seek medical care as soon as possible. Patients with diabetes have a higher risk for MI and worse prognosis compared to patients without diabetes. Previous research is inconclusive regarding symptoms and pre-hospital delay times in MI among patients with diabetes and there is lack of research in how patients with diabetes perceive, interpret and respond to MI symptoms. Aim: The overall aim of this thesis was to explore symptoms and care seeking behaviour during MI in patients with diabetes. Methods: This thesis comprises four studies. Studies I and II were based on data from the Northern Sweden MONICA myocardial infarction registry to describe symptoms in 4028 patients (I) and pre-hospital delay and factors associated with pre-hospital delay of ≥ 2 h in 4266 patients (II). Study III included 694 patients, at five hospitals in Sweden. The patients answered a questionnaire about symptoms, response to symptoms and delay times in MI. In study IV data were collected through interviews about experiences of getting MI and the decision to seek medical care. Results: Study I showed that typical MI symptoms according to MONICA criteria were common in both men and women, both with and without diabetes, and no differences between the groups were found. Study II showed that more patients with diabetes had pre-hospital delay times of ≥ 2 h compared to patients without diabetes. In Study III, chest pain was the most common self-reported MI symptom in patients with and without diabetes and there were no differences between the groups. Shoulder pain/discomfort, shortness of breath and tiredness were more common in patients with diabetes whereas cold sweat was less common compared to patients without diabetes. Less than 40 % of patients with diabetes called the emergency medical services (EMS) as their first medical contact (FMC) and about 60 % initially contacted a spouse after symptom onset. Patients with diabetes reported longer patient delay than patients without diabetes, but after age and gender adjustments the results were not significant. Pain, pressure or discomfort in the stomach, anxiety, symptoms that come and go and thoughts that the symptoms would disappear were associated with longer patient delay in patients with diabetes. In study IV, the analysis revealed the core category “Becoming ready to act” and the categories perceiving symptoms, becoming aware of illness, feeling endangered, and acting on illness experience. Patients with diabetes described a variety of different MI symptoms, the onsets of MI varied and it was sometimes difficult to interpret symptoms as related to MI. The decision to seek medical care for MI was complex with several barriers for timely care seeking. Conclusion: Chest pain was common in patients with diabetes and in contrast to our hypothesis chest pain was equally common in both patients with and without diabetes. There were more similarities than differences in MI symptoms between patients with and without diabetes. However, patients with diabetes were more likely to have pre-hospital delay for 2 hours or more compared to those without diabetes and there seems to be an underutilization of the use of emergency medical services as first medical contact. The process to seek care for MI was complex, initiated by perceiving symptoms, followed by illness awareness, feelings of being endangered and finally acting on the illness experience.

Tracheal Extubation of Patients Cared for in the Anesthesia Setting : Experiences Described by Registered Nurse Anesthetists and Anesthesiologists
- 2020
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background In Sweden, extubation is an interdisciplinary process involving teamwork between Registered Nurse Anesthetists (RNA) and Anesthesiologists, and comprehensive demands are placed on the professionals providing anesthesia. The extubation of the endotracheal tube after General Anesthesia (GA) is a critical moment for the patient. In that moment, the patient is in a vulnerable state and at risk of suffering severe complications, such as hypoxia, laryngospasm, aspiration, and hypertension. Anesthesia deals with identifying options, making risk assessments and reconsiderations. Clinical decision-making in anesthesia includes making decisions quickly and sometimes re-evaluating these just as quickly. In the often brief meeting prior to anesthesia, a relationship with the patient emerges and an unspoken demand arises: to care for the life that is placed in the hands of the anesthetists.Aim The overall aim was to gain an understanding of the Registered Nurse Anesthetists’ and Anesthesiologists’ experiences of their decision-making practices in the process of extubation of the endotracheal tube in the anesthesia setting with patients undergoing general anesthesia.Method This licentiate thesis consists of two studies (I, II), both conducted with a qualitative design using focus-group interviews (I) and Individual interviews (II) to collect data. A total of 20 RNAs from two hospitals and 17 Anesthesiologists from three hospitals were included, using a consecutive sampling strategy. Both studies were analyzed with qualitative content analysis and adopted an inductive approach to seek a deeper understanding of the phenomena, using manifest content analysis. In order to explore how the RNAs and Anesthesiologists experience the process of extubation and to identify nuances between them, the two studies were merged together in this licentiate thesis.Results When merging these studies (I, II) together by combining subcategories from both, six themes emerged. The theme, Assembling unique decisions, deals with the how the RNAs (I) and Anesthesiologists (II) assess, prepare, prevent and reconsider when planning for the extubation. Acting upon sensibilities consists of them recognizing patterns, leaning on their experience, and being receptive to different inputs from the patient and other professionals. The third theme, Being guided by intuition, included how the RNAs and Anesthesiologists relied on their feelings and were guided by emotions when deciding when to extubate. Safeguarding the patient deals with them protecting and acting as an advocate for the patient and how they focus on and are humble in the process of extubation. In the fifth theme, Being in a vulnerable position, the RNAs (I) felt they were on their own when making the decision on when to extubate, while the Anesthesiologists (II) felt as if they were one of the team. Using their own receptivity included how they established a connection with the patient and sensed the atmosphere.Discussion In their first encounter with the patient, or when obtaining knowledge about the patient, the RNAs and Anesthesiologists had already started to tailor a mental plan of the extubation unique to each patient. The plan consisted of small pieces of information being gathered and assembled together during the anesthesia, and this information is then combined with their experience of similar situations and with their intuition with the aim of safeguarding the patient. RNAs and Anesthesiologists act upon sensibilities when deciding on when to extubate. These strategies align with the concept of phronesis, a form of knowledge understood as practical wisdom that facilitates good clinical judgement in being rational, which is based on pre-understanding, experience, and interpersonal relationships and which is difficult to teach to someone else.

Primary hyperhidrosis : prevalence and impacts for the individual
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Primary hyperhidrosis, excessive sweating, is a condition with unknown prevalence in many parts of the world. The disease debuts in adolescence and it affects men and women in equal proportions. A genetic background exists and the most common localisation on the body for excessive sweating is the axillary region. It is known that primary hyperhidrosis reduces quality of life and interferes with daily activities. Affected individuals often hide their sweating problems and the disease may lead to social withdrawal and isolation. Although botulinum toxin is an effective and available treatment, relatively few persons with primary hyperhidrosis seek medical healthcare and a minority of those are men.We investigated the prevalence of primary hyperhidrosis in Sweden and how the disease impairs quality of life, changes in daily activities, signs of depression and anxiety and alcohol consumption before and after treatment with botulinum toxin. The severity of hyperhidrosis according to the affected body sites was also investigated. Further on we explored mens experiences living with primary hyperhidrosis by interviews and content analysis.Our results showed that primary hyperhidrosis occurs in 5.5% of the Swedish population. The disease reduces quality of life and affects mainly the psychological health of the individuals. Persons with palmar and axillary hyperhidrosis rated their symptoms more severe and with much higher impact on their quality of life compared to persons suffering from hyperhidrosis elswhere on the body. Individuals with axillary hyperhidrosis more often reported a later debut and signs of peripheral vasoconstrictions were more common in this group compared to individuals with palmar hyperhidrosis. This made us believe that factors other than genetics seem to play a role in triggering axillary hyperhidrosis. Treatment with botulinum toxin A had a significant effect in reducing the symptoms and their interferences on daily life while increasing the overall quality of life. Signs of depression, stress and anxiety were also significantly reduced by treatment. This treatment was safe and no serious side-effects were noted. Qualitative content analysis of interviews with 15 men suffering from primary hyperhidrosis resulted in the theme: To be captured in a filthy body. The experiences of men with excessive sweating were thus interpreted as stigmatising. Stigma has a negative effect on mental health which reinforces our findings in quantitative studies when investigating quality of life. It is our assumption that the symptoms act as a vicious circle reducing quality of life, stigmatising the individual and limiting daily interactions. Addressing hyperhidrosis with information when the disease debuts in young people could reduce the stigma and enable early intervention via healthcare which may have a significant effect on the life of those affected.

Improving venous blood specimen collection practices : method development and evaluation of an educational intervention program
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: About 60%–80% of decisions regarding diagnosis and treatment are based on laboratory test results. Low adherence to venous blood specimen collection (VBSC) guidelines may lead to erroneous or delayed test results, causing patient harm and high healthcare costs. Educational intervention programs (EIPs) to update, improve and sustain VBSC practices are seldom evaluated. After testing a self-reported venous blood sampling questionnaire, the overall aim of this thesis was to evaluate the impact of a large-scale EIP on healthcare personnel’s VBSC practices.Methods: The study settings were primary healthcare centres (PHCs) in northern Sweden. Participants were VBSC personnel. Data consisted of a VBSC questionnaire of self-reported practices, records of low-level haemolysis index in serum samples (specimen quality indicator), and interviews reflecting VBSC practices. First, experts on questionnaires and VBSC were consulted, and test-retest statistics were used when testing the VBSC questionnaire for validity and reliability. Thereafter, we evaluated the impact of a short, large-scale EIP with a before-after approach comparing self-reported VBSC questionnaire of two county councils. The personnel of the county councils (n = 61 PHCs) were divided into an intervention group (n = 84) and a corresponding control group (n = 79). In order to test changes in blood specimen quality we monitored haemolysis in serum samples (2008, n = 6652 samples and 2010, n = 6121 samples) from 11 PHCs. Finally, 30 VBSC personnel from 10 PHCs reported their experiences. The interview questions were open-ended with reflective elements and the interviews were analysed by qualitative content analysis.Results: The VBSC questionnaire was found to be valid and could be used to identify risk of errors (near misses) and evaluate the impact of an EIP emphasising VBSC guideline adherence. The intervention group demonstrated several significant improvements in self-reported practices after the EIP, such as information search, patient rest, test request management, patient identification, release of venous stasis, and test tube labelling. The control group showed no significant improvements. In total, PHCs showed minor differences in blood specimen quality. Interviews summarized VBSC personnel experiences in the overall theme: education opened up opportunities for reflection about safety. Conclusion: This thesis is, to our knowledge, the first to evaluate the impacts of a large-scale EIP on VBSC practices. The VBSC questionnaire and monitoring for low-level haemolysis reflected VBSC practices. The frequently occurring near-miss markers made it possible to compare and benchmark VBSC practices down to the healthcare unit and hospital ward. The short, general EIP opened up opportunities for reflection about safety and improved VBSC practices in PHCs with larger deviations from guidelines. EIPs that provide time for reflection and discussion could improve VBSC further. Directed EIPs focused on specific VBSC flaws might be more effective for some near misses in VBSC practices, while some near misses must be changed at a different level in the system.Clinical relevance: Our results indicate that monitoring and counteracting the near misses in VBSC practices is a well-functioning preventive action. We propose that the VBSC monitoring instruments (VBSC questionnaire & haemolysis index) we used and the EIP strategy proposed should be tested in additional countries with different healthcare settings. It is suggested that a national program intended to identify near misses and prevent VBSC errors be developed in the healthcare system. General e-learning programs may be cheaper than, and as effective as, the EIP program and may be performed everywhere and any time. Systematic planning, useful for reflection and with focus on the specific elements in a skill, together with VBSC guidelines, could probably increase improvements. Our studies have led to deeper and extended knowledge of the impact of an EIP on VBSC practices. Our results can be used when considering future VBSC practice interventions. Using a model for practical skills in nursing to describe VBSC in a more holistic and less technical way might highlight VBSC as a practical nursing skill.

Exploring firefighters' health and wellbeing
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: This thesis supports the assumption that firefighters’ health and mental well-being is important, in order to cope with the stress that the profession implies. As health is an essential part of everyday life, it seems substantially to understand how an almost exclusively male workforce of firefighters construct their discourse in relation to health and well-being. The overall purpose of this thesis is to explore health and ill-health among firefighters in relation to their work environment, including coping strategies, critical incidents and ‘ordinary’ day-to-day work at the fire and rescue service station.Methods: In Study I, 180 firefighters (16 women, 164 men) answered an open-ended question. Qualitative content analysis was used based on free text answers and focused on critical incidents. Study II, was based on a cross-sectional survey measuring burnout, psychosocial work environment and coping strategies. Participants were randomly selected and the final sample consisted of 476 firefighters (58 women, 418 men) and analyzed with multiple linear regression. In Study III and Study IV, a total of 28 fire-fighters (4 women and 24 men) participated in the study. Regarding Study IV a strategic sample of policy documents was also included. For Study III and IV, the research questions was dealt with applying critical discourse analysis on the focus group discussions (FGD) and individual interviews. In Study IV the analysed material also included policy documents.Results: Findings from Study I were presented in four categories; ‘overwhelming critical situations’, ‘risks of delay, ‘risk of failure’ and ‘risks to oneself’. Women in Study I described their experiences in a more distanced account, while men described their experiences more vividly. Results from Study II showed overall low mean values in the burnout scales of emotional exhaustion (EE) and depersonalization (DP) among both women and men. Only 2 % of women and 1% of men scored high levels of EE, and only 2% of women and 3% of men scored high level of DP. A multiple linear regression showed that high demand and lack of social support contributed significantly to predicting EE among men. The coping strategies among firefighters influence the level of EE and DP, and these strategies were different between women and men. In Study III six dominant themes were identified. A strong sense of the firefighter community was articulated as health promoting. The physical exercise at work and the balance between emergency and station work were also two recurrent theme supporting firefighters’ health. Another health-promoting theme concerns clarity of roles among firefighters. Peer support and tolerance in the work group was another common theme, alongside with expressions of the firefighter as hero or helper. Themes described as hindrances to health and well-being in firefighters’ discourse were; diversity, preventive work and education. All hindrance themes were articulated as important struggles in the firefighter discourse against changes in work. In Study IV, we have identified two sides in the struggles, on the one hand we have the ‘insiders’, a majority of male firefighters working in the fire and rescue services representing a collective defending its autonomy and traditions. On the other hand we have the ‘outsiders’, represented by the government, the Swedish Civil Contingencies Agency, (MSB), municipalities, politicians at different levels and academic researchers.Conclusion: Firefighters described critical incidents at work as overwhelming situations, along with negative experiences of organizational and practical tasks. Despite these experiences firefighters were reported as healthy according to EE and DP (Study I and II). Results of Study II also showed a relationship between psychosocial work environment and burnout among men, but not among women. The coping strategies among firefighters influence the level of burnout, and these strategies differ between women and men. The well-being in firefighters’ discourse, at least partly, is gained from a strong sense of belonging to a homosocial group characterized by closeness to each other and peers who take care of each other. The firefighters in our studies articulate this community-sense, and describe the importance of the similarity, rather than diversity (Studies III and IV). Findings from our studies regarding health and well-being, add knowledge to the current explanations relating to firefighters’ resistance to change.

Cardiovascular aspects on chronic obstructive pulmonary disease : with focus on ischemic ECG abnormalities, QT prolongation and arterial stiffness
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Chronic Obstructive Pulmonary disease (COPD) is an under-diagnosed disease with a prevalence of approximately 10%, highly dependent on age and smoking habits. Comorbidities are common in COPD and of these, cardiovascular diseases (CVD) are the most common. COPD is the fourth leading cause of death globally, and CVD probably contribute to the high mortality. Within CVD, Ischemic Heart Disease (IHD) is the most common. It is highly clinically relevant to identify signs of ischemic heart disease, other cardiac conditions, and risk factors for CVD in COPD. Electrocardiogram (ECG) is a simple but still major diagnostic tool in clinical cardiology, including disturbances in the electric conduction system and ischemia. Due to the under-diagnosis of COPD, there is limited knowledge regarding the prevalence and prognostic impact of ECG abnormalities in COPD. Arterial stiffness is a risk factor for CVD, which has raised an increased interest, however not evaluated in population based studies of COPD.Aim: The overall aim was to describe cardiovascular aspects on COPD, with a specific focus on arterial stiffness, prevalence and prognostic impact of ischemic ECG abnormalities and prolonged QT interval, by comparing subjects with and without obstructive lung function impairment in a population-based cohort.Methods: The thesis is based on the Obstructive Lung Disease in Northern Sweden (OLIN) COPD study; a population-based longitudinal cohort study. During the years 2002-2004, all participants in clinical examinations from previously recruited large population-based cohorts were invited to re-examination including spirometry and a structured interview. All subjects with obstructive lung function impairment (n=993) were identified, together with 993 age and sex-matched referents without airway obstruction. The study population (n=1986) has been invited to annual examinations since 2005 including spirometry and structured interview. Papers I-III are based on data from 2005 when electrocardiogram (ECG) was recorded in addition to the basic program. All ECGs were Minnesota coded and QT-time was measured. Paper IV is based data from 2010 when non-invasive measurements of arterial stiffness, assessed as pulse wave velocity (PWV), was added to the program. Spirometric data were classified as normal lung function (NLF), restrictive spirometric pattern (RSP) and airway obstruction (COPD). The following spirometric criteria for COPD were used: post-bronchodilator FEV1/VC<0.70 (papers I-IV, in paper III labelled GOLD-COPD) and lower limit of normal, LLN (LLN-COPD) (paper III). Spirometric classification of COPD severity was based on FEV1 % predicted as a continuous variable or according to the Global Initiative for Obstructive Lung Disease (GOLD), divided into GOLD 1-4.Results: The prevalence of ischemic heart disease (IHD), both self-reported and assessed as probable and possible ischemic ECG abnormalities (I-ECG) according to the Whitehall criteria, was similar among subjects with NLF and COPD. The prevalence of both self-reported and probable (I-ECG) according to Whitehall increased by GOLD grade. Among those with COPD, self-reported IHD was associated with disease severity, assessed as FEV1 % predicted also after adjustment for age and sex (paper I).In both COPD and NLF, those with I-ECG had a higher cumulative mortality over 5 years than those without I-ECG (29.6 vs. 10.6%, p<0.001 and 17.1 vs. 6.3 %, p=0.001). When analysed in a multivariate model, the Mortality Risk Ratio (MRR, 95%CI) was increased for subjects with COPD and I-ECG (2.4, 1.5-3.9), and non-significantly so for NLF with I-ECG (1.65, 0.94-2.90), when compared to NLF without I-ECG. When analyzed separately among subjects with COPD, the increased risk for death associated with I-ECG persisted independent of age, sex, BMI-class, smoking habits and disease severity assessed as FEV1 % predicted (1.89, 1.20-2.99). The proportion without reported IHD was high among those with I-ECG; 72.4% in NLF and 67.3% in COPD. The pattern was similar also among them; I-ECG was associated with an increased risk for death in COPD and non-significantly so in NLF (paper II).Mean corrected QT-time (QTc) and prevalence of QTc prolongation was higher in RSP than NLF but similar in NLF and GOLD-COPD. The prevalence of borderline as well as prolonged QTc increased by GOLD grade (test for trend p=0.012 for both groups). Of those with GOLD-COPD, 52% fulfilled the LLN-criterion (LLN-COPD). When comparing LLN-COPD and NLF, the pattern was similar as when comparing NLF and GOLD-COPD. The cumulative mortality over 5 years was higher among subjects with borderline and prolonged QTc than those with normal QTc in subjects with GOLD-COPD and LLN-COPD but not in NLF and RSP (paper III).Arterial stiffness, assessed as PWV, was higher in GOLD 3-4 compared to non-COPD (10.52 vs. 9.13 m/s, p=0.042). Reported CVD and age >60 were both associated with significantly higher PWV in COPD as well as in non-COPD. In a multivariate model, GOLD 3-4 remained associated with higher PWV when compared with non-COPD, also when adjusted for sex, age group, smoking habits, blood pressure, reported CVD and pulse rate (paper IV).Conclusion: In this population-based study, the prevalence of ischemic ECG abnormalities was similar among subjects with normal lung function and COPD, but increased by disease severity among subjects with COPD. Ischemic ECG abnormalities were associated with an increased mortality among subjects with COPD, independent of common confounders and disease severity, also among those without known heart disease. Whilst the prevalence of QTc prolongation was similar in NLF, COPD and LLN-COPD, it was associated with an increased mortality only in the COPD-groups. ECG is a simple non-invasive method and seems to identify findings of prognostic importance among subjects with COPD. Central arterial stiffness, a known risk factor for cardiovascular disease, was increased among subjects with severe and very severe COPD when compared to subjects without COPD independent of common confounders.

Postoperative recovery : development of a multi-dimensional questionnaire for assessment of Recovery
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aims to present a multi-dimensional instrument for self-assessment of progress in postoperative recovery. The author employs different research paradigms and methodologies to achieve this aim. Walker and Avant’s approach to concept analysis was used to examine the basic elements of postoperative recovery (Study I). The analysis identified different recovery dimensions and developed a theoretical definition showing postoperative recovery to be an energy-requiring process of returning to normality and wholeness, defined by comparative standards. Fourteen patients and 28 staff members participated in individual and focus group interviews aimed at describing patient and staff experiences of patient recovery (Study II). The essence of the postoperative recovery process was described as a desire to decrease unpleasant physical symptoms, reach a level of emotional wellbeing, regain functions, and re-establish activities. In Study III, 5 dimensions and 19 items were identified as a part of the operationalization process of the concept postoperative recovery. Fifteen staff members and 16 patients participated in the evaluation of content validity. On average, 85% of the participants considered the items as essential to the recovery process. In a test run of the questionnaire, 14 of 15 patients considered the questionnaire to be easy to understand and easy to complete. Twenty-five patients participated in the evaluation of intra-patient reliability. Percentage agreement (PA), systematic disagreement (RP, RC), and individual variability (RV) between the two assessments were calculated. PA measures ranged from 72% to 100%. The observed disagreement could be explained mainly by systematic disagreement. In total, 158 patients participated in the evaluation of construct validity, the ability to discriminate between groups, and the investigation of important item variables (Study IV). A rank-based statistical method for evaluation of paired, ordered categorical data from rating scales was used to evaluate consistency between the assessments of the Postoperative Recovery Profile (PRP) questionnaire and a global recovery scale. The number of months needed by participants to be regarded as fully recovered was studied by means of recovery profiles displayed by the cumulative proportion of recovered participants over time. A ranking list based on the participant’s appraisal of the five most important item variables in the PRP questionnaire was compiled to illustrate the rank ordering of the items. In comparing the assessments from the PRP questionnaire and the global recovery scale, 7.6% of all possible pairs were disordered. Twelve months after discharge 73% in the orthopaedic group were regarded as fully recovered, compared to 51% of the participants in the abdominal group (95% CI: 6% to 40%). The pain variable appeared among the top five most important items on eight measurement occasions, of eight possible, in both study groups. In conclusion, the PRP questionnaire was developed and support was given for validity and reliability. The questionnaire enables one to evaluate progress in postoperative recovery.

Burnout, work, stress of conscience and coping among female and male patrolling police officers
- 2013
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background. Police work is a stressful occupation with frequent exposure to traumatic events and psychological strain from work might increase the risk of burnout. This thesis focuses on patrolling police officers (PPO), who work most of their time in the community and have daily contact with the public. Since police work traditionally is a male coded occupation we assume that there are differences between women and men in burnout as well as experiences from psychosocial work environment.Aim. The overall aim of this thesis is to explore burnout, psychosocial and physical work environment, coping strategies, and stress of conscience when taking gender into consideration among patrolling police officers.Methods. This thesis employs both qualitative and quantitative methods. In Paper I a qualitative approach with narrative interviews was used where male PPO described experiences of traumatic situations when caring for victims of traffic accidents. A convenience sample of nine male PPO from a mid-sized police authority was recruited. Interviews were analyzed using qualitative content analysis. Papers II, III, and IV were based on a cross-sectional survey from a randomly selected sample stratified for gender from all 21 local police authorities in Sweden. In the final sample, 1554 PPOs were invited (778 women, 776 men), response rate was 55% (n=856) in total, 56% for women (n=437) and 53% for men (n=419). The survey included a self-administered questionnaire based on instruments measuring burnout, stress of conscience, psychosocial and physical work environment, and coping.Results. Findings from Paper I were presented in three themes; “being secure with the support system,” “being confident about prior successful actions,” and “being burdened with uncertainty.” Results from Paper II showed high levels of emotional exhaustion (EE), 30% for female PPOs and 26% for male PPOs. High levels of depersonalization (DP) were reported for 52 % of female PPO, corresponding proportions for male were 60%. Multiple logistic regression showed that stress of conscience (SCQ-A), high demand, and organizational climate increased the risk of EE for female PPO. For male PPO stress of conscience (SCQ-A), low control and high demand increased the risk of EE. Independent of gender, stress of conscience (SCQ-A) increased the risk of DP. Psychometric properties of the WOCQ were investigated with exploratory factor analysis and confirmatory factor analysis, a six-factor solution was confirmed. DIF analysis was detected for a third of the items in relation to gender. In Paper IV a block wise hierarchical multiple regression analysis was performed investigating the predictive impact of psychological demand, decision latitude, social support, coping strategies, and stress of conscience on EE as well as DP. Findings revealed that, regardless of gender, risk of EE and DP increased with a troubled conscience amongst the PPO.Conclusion. “Being burdened with uncertainty” in this male-dominated context indicate that the PPO did not feel confident talking about traumatic situations, which might influence their coping strategies when arriving to a similar situation. This finding can be related to Paper II and IV showing that stress of conscience increased the risk of both EE and DP. The associations between troubled conscience and the risk of experiencing both emotional exhaustion and depersonalization indicate that stress of conscience should be considered when studying the influence of the psychosocial work environment on burnout. Results from this study show that the psychosocial work environment is not satisfying and needs improvement for patrolling police officers in Sweden. Further studies including both qualitative and quantitative (longitudinal) methods should be used to improve knowledge in this area to increase conditions for preventive and rehabilitative actions.

Purpose in life among very old people
- 2010
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to explore purpose in life among very old people. The proportion of elderly is increasing in Sweden, especially among the group of very old aged over 85 years. Ageing has been associated from some perspectives with health, wisdom, maturity, and inner strength. Ageing can also, however, lead to reduced physical function, cognitive impairments, and loss of purpose in life. A loss of purpose in life can lead to mental health problems such as depression. This thesis is part of the Umeå 85 + study/GERDA begun in 2000. Half of all 85-year-olds, all 90-year-olds, and all those 95 years of age or older living in the municipality of Umeå were invited to the larger study, which was expanded in 2002 to include five rural municipalities in Västerbotten County with the same inclusion criteria. The Umeå 85 + study/GERDA is a collaborative project between several departments at Umeå University.Selection criteria for participants in the thesis were the ability to answer Likert-type questionnaires and the ability to participate in interviews. A follow-up study was conducted in Umeå in 2005 and in Västerbotten County in 2007. Paper I is a cross-sectional study with 189 participants (120 women and 69 men) who had responded to several questionnaires including the Purpose in Life test (PIL). In the results women scored significantly lower on the PIL test than men; attitudes towards one’s own aging were associated with purpose in life for both men and women; and musculoskeletal disorders were associated with lower purpose in life in women. Paper II includes the 189 participants from study I. In results at baseline the 40 who were diagnosed with depression had significantly lower purpose in life, and women were diagnosed with depression more often than men (32/120 women and 8/69 men). The 40 participants with a diagnosis of depression were excluded five years later, when 78 of 149 participants were available for the follow-up, 21 of whom (26.9%) had developed depression. There was no difference in the mean scores on the PIL test between those who had developed depression and those who had not. Purpose in life does not seem to protect very old people from developing depression.Paper III includes 51 people who responded to the PIL test on two occasions five years apart, and its results show that purpose in life decreased after five years. There was no difference in mean PIL scores at baseline between those with a diagnosis of depression and those without depression, but purpose in life declined significantly over the five years in those with diagnosed depression. In study IV, to gain a deeper understanding of purpose in life, content analysis was conducted on interviews from 30 women. To obtain 5 variety and breadth in the stories we selected 10 women with low estimated purpose in life, 10 women with undecided estimated purpose, and 10 women with high estimated purpose in life. The results show that despite the fact that women estimated their purpose in life lower than men, their stories were positive. The women experienced purpose in their daily life where social relations was important and on a spiritual level. However, there were also expressions of experiencing life as simply existing. In Study V we included 23 men who had responded to a question about purpose in life. Their answers were subjected to content analysis and the results show that for men work is an important part of purpose in life. All men except one had a positive outlook on life, and the men found purpose in life most strongly in memories of when they were younger.Lack of purpose in life can result in mental disorders like depression. Stereotypes of older people can affect their views of their own ageing, which in turn can weaken their purpose in life. To prevent mental illness it is important to experience purpose in life throughout life. Society at large and the health care system must consider purpose in life integral to mental health and work to combat ageist stereotypes to support purpose in life through the entire lifespan.

- Background Within trauma teams, effective communication is necessary to ensure safe and secure care of the patient. Deficiencies in communication are one of the most important factors leading to patient harm. Time is an essential factor for rapid and efficient disposal of trauma teams to increase patients’ survival and prevent morbidity. Trauma team training plays an important role in improving the team’s performance, while the leader of the trauma team faces the challenge of coordinating and optimizing this performance.Aim The overall aim of this thesis was to analyse how members of trauma teams communicated verbally and non-verbally during trauma team training in emergency settings, and how the leaders were positioned or positioned themselves in relation to other team members. The aim was also to investigate the use of a communication tool, closed-loop communication, and the time taken to make a decision to go to surgery in relation to specific factors in the team as well as the leader’s position.Methods Eighteen trauma teams were audio and video recorded and analysed during regular in situ training in the emergency room at a hospital in northern Sweden. Each team consisted of six participants: two physicians, two nurses, and two enrolled nurses, giving a total of 108 participants. In Study I, the communication between the team members was analysed using a method inspired by discourse psychology and Strauss’ concept of “negotiated orders”. In Study II, the communication in the teams was categorized and quantified into “call-outs” and “closed-loop communication”. The analysis included the team members’ background data and results from Study I concerning the leader’s position in the team. Poisson regression analyses were performed to assess closed-loop communication (outcome variable) in relation to background data and leadership style (independent exploratory variables). In Study III, quantitative content analysis was used to categorize and organize the team members’ positions and the leaders’ non-verbal communication in the video-recorded material. Time sequences of leaders’ non-verbal communications in terms of gaze direction, speech time, and gestures were identified separately to the level of seconds and presented as proportions (%) of the total training time. The leaders’ vocal nuances were also categorized. The analysis in Study IV was based on the team members’ background data, the results from Study I concerning the leader’s position in the team, and the categorization and quantification of team communication from Study II. Cox proportional hazard regression was performed to assess the time taken to make a decision to go to surgery (outcome variable) in relation to background data, the leader’s position, and closed-loop communication (independent variables).Results The findings in Study I showed that team leaders used coercive, educational, discussing, and negotiating repertoires to convey knowledge and create common goals of priorities in work. The repertoires were used flexibly and changed depending on the urgency of the situation and the interaction between the team members. When using these repertoires, the team leaders were positioned or positioned themselves in either an authoritarian or an egalitarian position. Study II showed that closed-loop communication was used to a limited extent during the trauma team training. Call-out was more frequently used by team members with eleven or more years in the profession and experience of trauma within the past year, compared with team members with no such experience. Scandinavian origin, an egalitarian team leader and previous experience of two or more structured trauma courses were associated with more frequent use of closed-loop communication compared to those with no such origin, leader style, or experience. Study III showed that team leaders who gained control over the “inner circle” used gaze direction, vocal nuances, verbal commands, and gestures to solidify their verbal messages. Leaders who spoke in a hesitant voice or were silent expressed ambiguity in their non-verbal communication, and other team members took over the leader's tasks. Study IV showed that the team leader’s closed-loop communication was important for making the decision to go to surgery. In 8 of 16 teams, decisions on surgery were taken within the timeframe of the trauma team training. Call-outs and closed-loop communication initiated by the team members were significantly associated with a lack of decision to go to surgery.Conclusions The leaders used different repertoires to convey and gain knowledge in order to create common goal in the teams. These repertoires were both verbal and non-verbal, and flexible. They shifted depending on the urgency of the situation and the interaction within the team. Depending on the chosen repertoire, the leaders were positioned or positioned themselves as egalitarian and/or authoritarian leaders. In urgent situations, the leaders used closed-loop communication as part of a coercive repertoire, and called out commands and directed requests to specific team members. This repertoire was important for making the decision to go to surgery; the more closed-loop communication initiated by the leader, the more likely that the team would make a decision to go to surgery. Problems arose if the leaders were positioned or positioned themselves as either an authoritarian or an egalitarian leader. The leaders needed to be flexible and use different repertories in order to move the teamwork forward. It was notable that higher numbers of call-outs and closed-loop communication initiated by the team members decreased the probability of making the decision to go to surgery.
