- AIMS: To investigate the importance of macro-organizational factors, i.e. organizational sociodemographic and socioeconomic preconditions, of the municipal incidence of long-term sick leave, disability pension, and prevalence of workers with long-term work ability among home care workers. METHODS: In an ecological study design, data from national databases were combined by record linkage. Descriptive and analytical statistics were used to estimate and interpret macro-organizational factors (economic resources, region, unemployment, employment, occupational rehabilitation, return to work, age structures of inhabitants and home care workers). RESULTS: The incidence of long-term sick leave among female home care workers was twice as high as that of male home care workers, and incidence of disability pension was about four times as high for the women. A great variation in municipal incidence of long-term sick leave, disability pension, and long-term work ability (101-264, 0.6-19.6, and 913-1,279 per 1,000 full-time equivalent workers and year) was also found. The strongest single factor for long-term work ability was a high proportion of part-time or hourly paid employees, which explained 35% of the municipal variation. Macro-organizational factors explained long-term work ability (47-62% explained variance) better than long-term sick leave (33% explained variance). There was a low rehabilitation activity; only 2% received occupational rehabilitation and 5% of those on sick leave longer than 2 weeks returned to work within 30 days. CONCLUSIONS: The differences in the municipal proportion of work ability incidence indicate a preventive potential, especially related to employment and return to work after sick leave.

Improved system design of an emergency department through simulation-based multiobjective-optimization
- 2014

Konferensbidrag (refereegranskat)abstract
- Healthcare facilities, and especially emergency departments (ED), are usually characterized by its complexity due to the variability and stochastic nature of the processes involved in the system. The combination of different flows of patients, staff and resources also increments the complexity of this kind of facilities. In order to increase its efficiency, many researchers have proposed discrete-event simulation (DES) as a powerful improvement tool. However, DES can be a limited approach in the case a simulation model has too many combinations of input parameters, complex correlations between the input and output parameters and different objective functions. Hence, to find the best configuration of a complex system, an approach combining DES and meta-heuristic optimization becomes an even more powerful improvement technique. Simulation-based multiobjective-optimization (SMO) is a promising approach to generate multiple trade-off solutions particularly when multiple conflicting objectives exist within a complex system. The generated solutions provide decision makers with feasible and optimal alternatives to improve, modify or design healthcare systems. The aim of this paper is to present the work done at the ED of the regional Hospital of Skövde in Sweden, where SMO implemented in modeFromtier has been successfully applied. The result and methodology present a successful approach for decision makers in healthcare systems to reduce the waiting time of patients saving considerable time, money and resources.

- The aim of the present study was to evaluate the concordance (agreement) between VDU-users' ratings of comfort and ergonomists' observations of workplace layout, and the concordance between VDU-users' ratings of perceived exertion and ergonomists' observations of working postures during VDU-work. The study population consisted of 853 symptom free subjects. Data on perceived comfort in different dimensions and data regarding perceived exertion in different body locations were collected by means of a questionnaire. Data concerning workplace layout and working postures were collected with an observation protocol, by an ergonomist. Concordance between ratings of comfort and observations of workplace layout was reasonably good for the chair and the keyboard (0.60, 0.58) and good regarding the screen and the input device (0.72, 0.61). Concordance between ratings of perceived exertion and observations of working postures indicated good agreement (0.63-0.77) for all measured body locations (neck, shoulder, wrist and trunk). In conclusion ratings of comfort and perceived exertion could be used as cost-efficient and user-friendly methods for practitioners to identify high exposure to poor workplace layout and poor working postures.

- BackgroundRandomised controlled trials have shown an excellent preventive effect of statins on ischemic heart disease. Our objective was to investigate if a relation can be detected between acute myocardial infarction- (AMI) mortality or incidence and statin utilisation, for men and women in different age-groups on a population basis.ResultsThe utilisation rate of statins increased almost three times for both men and women between 1998 and 2002. During 1998-2000 the incidence of AMI decreased clearly for men but only slightly for women. Mortality decreased from 1998 to 2002. The change in statin utilisation from 1998 to 2000 showed no correlation to the change in AMI mortality from 2000 to 2002. Statin utilisation and AMI- incidence or mortality showed no correlations when adjusting for socio-economic deprivation, antidiabetic drugs and geographic coordinates.ConclusionsDespite a widespread and increasing utilisation of statins, no correlation to the incidence or mortality of AMI could be detected. Other factors than increased statin treatment should be analysed especially when discussing the allocation of public resources.
