- IntroductionInsufficient visual ability can lead to increased work load and contribute to eyestrain and musculoskeletal discomfort, since “the eye leads the body” (Anshel, 2005). It has been shown that visually demanding work, such as computer work, is associated with eye discomfort, headaches and muscle pains in mainly the neck and shoulders (Rosenfield, 2011).Although the relation between eyestrain and musculoskeletal discomfort is not fully understood, studies have shown that straining the eyes increases the musculoskeletal activity in neck and shoulders (trapezius), and an association between visually demanding work, eye problems, headache and/or muscle problems have been found (Aarås et al., 2001; IESNA, 2011, Richter et al., 2008; Zetterberg et al., 2013). Problems due to insufficient visual ergonomics not only exist in computer intensive jobs, but in other professions as well. For example, surgeons and other surgical personnel that report eyestrain also report twice as much musculoskeletal discomfort from the upper part of the body (Hemphälä et al., 2011). In an intervention study among postmen, both eyestrain and musculoskeletal discomfort decreased after a visual ergonomic intervention. The intervention included providing customized eyeglasses and optimal lighting conditions (Hemphälä et al., 2012). Apart from health and well-being being affected by a poor visual ergonomic work environment, quality and productivity may also be reduced (Eklund, 2009).The aim of this paper is to present the first version of a practical, easy-to-use, and time-efficient risk assessment method for visual ergonomics. The development of the method including the evaluation will also be described. With such a method, risk factors within the visual environment can hopefully be detected, and interventions implemented in order to reduce the prevalence of symptoms related to poor visual ergonomics among workers.MethodsA first version of the method has been developed, mainly based on existing checklists and instruments (Colon et al. 1999; Børsting et al., 2008, Knave et al., 1985, Sheedy and Shaw-McMinn, 2002; Wilson & Corlett, 2005). During spring 2015, 30 ergonomists will be updated about visual ergonomics and introduced to the risk assessment method. Each ergonomist will thereafter use the method in 10 workplaces, yielding data and practical experiences from 300 risk assessments. These data will then be used to test the validity and reliability of the method, and if necessary to further develop it.ResultsThe first version of the risk assessment method for Visual Ergonomics will be presented at IEA 2015, together with results from the approximately 300 risk assessments made by the ergonomists. So far, the factors included in the method are objective measurements such as illuminance, luminance contrast, uniformity values, expert assessment of the risk for glare, and subjective ratings of the visual ability, eyestrain and musculoskeletal discomfort.DiscussionThe presented method will be compared to other similar methods. The used method for development will be discussed in relation to validity and reliability. Finally the presented risk assessment method will be discussed in relation to usefulness in prevention of discomfort and work related disorders at work places.

- The complexity of modern interdisciplinary health care practices, where different specialties work together to solve complex problems, challenges traditional approaches to organizational development and quality improvement. An example of this is surgery. This article describes and evaluates an action-oriented method to facilitate organizational development and innovation at an operating unit, centered on interprofessional aspects of health care, a method that shares some features with action learning. At its core the method had a group with members from all specialties in an operating team, who participated in regular meetings facilitated by a process leader, according to experiential learning principles. The group was evaluated using mixed methods (including interaction process analysis (IPA)), of which video recorded group meetings and interviews constituted the main sources of data. Results showed that the group achieved a successful organizational change. Indications of the success of the group process were the low level of conflicts and the high level of task focus. Interprofessional boundaries appeared to be bridged as all members participated in formulation of both problems and solutions while not being afraid to voice different opinions. Problems could be attributed to lack of awareness of the group at the operating unit at which the intervention took place.

- BACKGROUND: /st>Previous research suggests that the World Health Organization Surgical Safety Checklist time-out reduces communication failures and medical complications and supports development of better safety attitudes. Previous research also indicates that different values can affect the implementation of interventions. OBJECTIVE: /st>To investigate the actual usage of the checklist in practice and to catalogue deviations for the purpose of identifying improvements. DESIGN: /st>Twenty-four surgical procedures were video recorded. The time-out was analysed quantitatively assessing compliance with a predefined observational protocol based on the checklist and qualitatively to describe reasons for non-compliance. SETTING: /st>The operating unit of a Swedish county hospital. MAIN OUTCOME MEASURES: /st>Compliance with checklist items and the participation of different personnel groups. Activities were conducted during the time-out. RESULTS: /st>Highest compliance was associated with patient ID, type of procedure and antibiotics; the worst with site of incision, theatre nurse team reviews and imaging information. Team member introductions occurred in half of the operations. Surgeons and the anaesthesia team dominated the time-out. CONCLUSION: /st>The checklist is not always applied as intended. The components that facilitate communication are often neglected. The time-out does not appear to be conducted as a team effort. It is plausible that the personnel's conception of risk and the perceived importance of different checklist items are factors that influence checklist usage. To improve compliance and involve the whole team, the concept of risk and the perceived relevance of checklist items for all team members should be addressed.
