    • BACKGROUND: Subarachnoid haemorrhage (SAH) is a devastating disease, with high mortality rate and substantial disability among survivors. Its causes are poorly understood. We aimed to investigate risk factors for SAH using a novel nationwide cohort consortium.METHODS: We obtained individual participant data of 949 683 persons (330 334 women) between 25 and 90 years old, with no history of SAH at baseline, from 21 population-based cohorts. Outcomes were obtained from the Swedish Patient and Causes of Death Registries.RESULTS: During 13 704 959 person-years of follow-up, 2659 cases of first-ever fatal or non-fatal SAH occurred, with an age-standardized incidence rate of 9.0 [95% confidence interval (CI) (7.4-10.6)/100 000 person-years] in men and 13.8 [(11.4-16.2)/100 000 person-years] in women. The incidence rate increased exponentially with higher age. In multivariable-adjusted Poisson models, marked sex interactions for current smoking and body mass index (BMI) were observed. Current smoking conferred a rate ratio (RR) of 2.24 (95% CI 1.95-2.57) in women and 1.62 (1.47-1.79) in men. One standard deviation higher BMI was associated with an RR of 0.86 (0.81-0.92) in women and 1.02 (0.96-1.08) in men. Higher blood pressure and lower education level were also associated with higher risk of SAH.CONCLUSIONS: The risk of SAH is 45% higher in women than in men, with substantial sex differences in risk factor strengths. In particular, a markedly stronger adverse effect of smoking in women may motivate targeted public health initiatives.

  • Legitimacy Work : Managing Sick Leave Legitimacy in Interaction
  • 2016
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis studies how sick leave legitimacy is managed in interaction and develops an empirically driven conceptualization of ‘legitimacy work’. The thesis applies an ethnomethodological framework that draws on conversation analysis, discursive psychology, and membership categorization analysis. Naturally occurring interaction is examined in two settings: (1) multi-party meetings at the Swedish Social Insurance Agency, in which participants assess and discuss the ‘status’ of the sick leave and plan for work rehabilitation; (2) peer-based online text-in-interaction in a Swedish forum thread that gathers people on sick leave.The thesis shows how mental states, activities and alternative categories function as resources for legitimacy work. However, such invocations are no straight-forward matter, but impose additional contingencies. It is thus crucial how they are invoked. By detailed analyses of the interaction, with attention to aspects such as lexicality and delivery, the thesis identifies a range of discursive features that manage sick leave legitimacy. Deployed resources are also subtle enough to be deniable as legitimacy work, that is, they also manage the risk of an utterance being seen as invested or biased.While legitimate sick leave is a core concern for Swedish policy-making, administration, and public debate on sick leave, previous research has for the most part been explanatory in orientation, minding legitimacy rather than studying it in its own right. By providing detailed knowledge about the legitimacy work that people on long-term sick leave do as part of both institutional and mundane encounters, the thesis contributes not only new empirical knowledge, but a new kind of empirical knowledge, shedding light on how the complexities of sick leave play out in real-life situations.Traditional sociological approaches have to a significant extent treated legitimacy as an entity with beginnings and ends that in more or less direct ways relate to external norms and cognitive states, or that focus on institutions, authority or government. By contrast, the herein emerging concept ‘legitimacy work’ understands legitimacy as a locally contingent practicality – a collaborative categorially oriented accomplishment that is integral to the interactional situation.

  • Developing guidelines in nursing care of children with Autism Spectrum Disorder in high technology health care settings
  • 2017
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction. The high technology environment such as a radiology and anaesthesia department in a typical health care setting can many times be a frightening environment for children. Children with neurodevelopmental disorders, such as Autism Spectrum Disorder (ASD), have problems with communication and social interaction. They are dependent on routines and can have higher sensitivity to sensory stimuli than other children. These children are one group who constitutes special challenges in reducing anxiety and creating participation in a high technology environment. This can make them prone to frightening encounters in health care settings if not cared for with special consideration.Aim: The overall aim of this thesis was to audit and enhance the care of children in a high technology environment in the health care system with a focus on children with Autism Spectrum Disorder.Methods: A descriptive design was used with both qualitative and quantitative methods. In Study I, 32 nurse anaesthetists were interviewed to explore the actions and experiences of caring for children in a high technology environment using a qualitative method, known as the Critical Incident Technique (CIT). In the two following studies (Study II, III) a cross-sectional design was used and two national surveys were performed to obtain knowledge on the status in Sweden regarding the care of children with ASD in high technology environments. Sixty-eight anaesthesia departments, 38 paediatric departments and 86 radiology departments responded to the survey. Descriptive statistic was used for the answers apart from the comments part of the questionnaire where qualitative content analysis was used. Due to the limited existence of guidelines in these environments, the creation ofevidence-based guidelines was performed in Study IV, using a Delphi method. The Delphi study was based on information gleaned from the previous studies and from the literature, and 21 experts identified in Study II and III were the expert panel developing the guidelines.Result: Nurses identified children with special needs such as children with ASD as a vulnerable group in a high technology environment (Study I). Seven departments in the anaesthesia context had guidelines for caring for children with ASD in the perioperative context. In the other departments, the care of children with ASD was dependent on the knowledge of the nurse presently working there (Study II). None of the radiology departments in Sweden had guidelines on how to care for children with ASD going through a radiographic examination without anaesthesia (Study III). As a result of Study I, II and III, the need for structured guidelines for caring for children with ASD in a high technology context was identified and a set of guidelines and a checklist was created. The guidelines relate to the organisational structure for the care of children with deficits in social interaction, communication, sensory sensitivity and dependence on routines. The checklist relates to gleaning information about the specific child to be able to give person-centred care based on the specific characteristic of the child (Study IV).Conclusion: Nurses working in a high technology environment in health care have diverse experiences of preventing anxiety in children with ASD coming for a challenging procedure. There are a limited number of evidence-based guidelines to decrease anxiety and to create participation in this group ofchildren. Evidence-based guidelines were created as a tool for enhancing person-centred care in a high technology environment for this group of children. The fact that several problems are assembled under one disorder makes ASD a useful condition to have as a basis for formulating national guidelines. Guidelines that cater for the care of children with ASD in a high technology environment using a person-centred approach may also extend to the care for children with other neurodevelopmental disorders that exhibit some of the same problems as children with ASD.

  • Psoriasis in Sweden : observational studies from an epidemiological perspective
  • 2016
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Background: Psoriasis is a heterogeneous disease with several clinical manifestations; the symptoms are characterized by redness, scaliness and thickness of the skin. There are several treatment options available for psoriasis and patients with moderate to severe psoriasis generally need systemic agents. In 2004 biologics were introduced for patients with moderate to severe psoriasis in Sweden.Methods: The Swedish Health Care Registers and the Swedish registry for systemic treatment of psoriasis PsoReg, were used to; estimate the incidence of psoriasis cases in the Swedish specialist care, to examine the treatment allocation and important factors related to the initiation of especially biologic treatment.Results: On average 9000 new psoriasis patients entered specialist care in Sweden each year under study, corresponding to an incidence of 98 patients per 100,000 person-years. In the treatment allocation analysis of the incident psoriasis cases in the Swedish specialist care Patients living in a Metropolitan Area and with a University degree were more likely to initiate a biologic treatment. By analysing biologic-naïve patients enrolled in PsoReg, PASI (the physician’s assessment of the psoriasis severity) and Psoriasis Arthropathy were shown to be two important factors associated with the initiation of biologic treatment while sex was not. Furthermore, it was also shown that the decision to initiate biological treatment was more strongly associated with PASI than with DLQI (the patients’ assessment of the disease impact Quality of Life).Conclusion: These studies indicate that there are inequalities in the assignments of systemic psoriasis treatments (especially in biologic treatment). Since the allocation of treatments should not depend on sex, education or residency in a Metropolitan Area but rather the need of care, it is important that future studies continue analysing possible factors that could influence the initiation of treatment in clinical practice.

  • Statistical methods for register based studies with applications to stroke
  • 2016
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This thesis adds to the area of register based research, with a particular focus on health care quality and (in)equality. Contributions are made to the areas of hospital performance benchmarking, mediation analysis, and regression when the outcome variable is limited, with applications related to Riksstroke (the Swedish stroke register).An important part of quality assurance is to identify, follow up, and understand the mechanisms of inequalities in outcome and/or care between different population groups. The first paper of the thesis uses Riksstroke data to investigate socioeconomic differences in survival during different time periods after stroke. The second paper focuses on differences in performance between hospitals, illustrating the diagnostic properties of a method for benchmarking hospital performance and highlighting the importance of balancing clinical relevance and the statistical evidence level used.Understanding the mechanisms behind observed differences is a complicated but important issue. In mediation analysis the goal is to investigate the causal mechanisms behind an effect by decomposing it into direct and indirect components. Estimation of direct and indirect effects relies on untestable assumptions and a mediation analysis should be accompanied by an analysis of how sensitive the results are to violations of these assumptions. The third paper proposes a sensitivity analysis method for mediation analysis based on binary probit regression. This is then applied to a mediation study based on Riksstroke data.Data registration is not always complete and sometimes data on a variable are unavailable above or below some value. This is referred to as censoring or truncation, depending on the extent to which data are missing. The final two papers of the thesis are concerned with the estimation of linear regression models for limited outcome variables. The fourth paper presents a software implementation of three semi-parametric estimators of truncated linear regression models. The fifth paper extends the sensitivity analysis method proposed in the third paper to continuous outcomes and mediators, and situations where the outcome is truncated or censored.

  • Diurnal variations in the quality of stroke care in Sweden
  • 2019
  • Ingår i: Acta Neurologica Scandinavica. - : Hindawi Limited. - 0001-6314 .- 1600-0404. ; 140:2, s. 123-130
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: A recent study of acute stroke patients in England and Wales revealed several patterns of temporal variation in quality of care. We hypothesized that similar patterns would be present in Sweden and aimed to describe these patterns. Additionally, we aimed to investigate whether hospital type conferred resilience against temporal variation. Materials and Methods: We conducted this nationwide registry-based study using data from the Swedish Stroke Register (Riksstroke) including all adult patients registered with acute stroke between 2011 and 2015. Outcomes included process measures and survival. We modeled time of presentation as on/off-hours, shifts, day of week, 4-hour, and 12-hour time blocks. We studied hospital resilience by comparing outcomes across hospital types. Results: A total of 113 862 stroke events in 72 hospitals were included. The process indicators and survival all showed significant temporal variation. Door-to-needle (DTN) time within 30 minutes was less likely during nighttime than daytime (OR 0.50; 95% CI 0.41-0.60). Patients admitted during off-hours had lower odds of direct stroke unit (SU) admission (OR 0.72; 95% CI 0.70-0.75). 30-day survival was lower in nighttime vs daytime presentations (OR 0.90, 95% CI 0.84-0.96). The effects of temporal variation differed significantly between hospital types for DTN time within 30 minutes and direct SU admission where university hospitals were more resilient than specialized non-university hospitals. Conclusions: Our study shows that variation in quality of care and survival is present throughout the whole week. We also found that university hospitals were more resilient to temporal variation than specialized non-university hospitals.

  • Time Trends and Monthly Variation in Swedish Acute Stroke Care
  • 2019
  • Ingår i: Frontiers in Neurology. - : Frontiers Media SA. - 1664-2295. ; 10
  • Tidskriftsartikel (refereegranskat)abstract
    • Background and Purpose: Studies of monthly variation in acute stroke care have led to conflicting results. Our objective was to study monthly variation and longitudinal trends in quality of care and patient survival following acute stroke.Methods: Our nationwide study included all adult patients (≥18 years) with acute stroke (ischemic or hemorrhagic), admitted to Swedish hospitals from 2011 to 2016, and that were registered in The Swedish Stroke Register (Riksstroke). We studied how month of admission and longitudinal trends affected acute stroke care and survival. We also studied resilience to this variation among hospitals with different levels of specialization. Results: We included 132,744 stroke admissions. The 90-day survival was highest in May and lowest in January (84.1 vs. 81.5%). Thrombolysis rates and door-to-needle time within 30 min increased from 2011 to 2016 (respectively, 7.3 vs. 12.8% and 7.7 vs. 28.7%). Admission to a stroke unit as first destination of hospital care was lowest in January and highest in June (78.3 vs. 80.5%). Stroke unit admission rates decreased in university hospitals from 2011 to 2016 (83.4 vs. 73.9%), while no such trend were observed in less specialized hospitals. All the differences above remained significant (p < 0.05) after adjustment for possible confounding factors. Conclusion: We found that month of admission and longitudinal trends both affect quality of care and survival of stroke patients in Sweden, and that the effects differ between hospital types. The observed variation suggests an opportunity to improve stroke care in Sweden. Future studies ought to focus on identifying the specific factors driving this variation, for subsequent targeting by quality improvement efforts.
