Although experiential prescribing maxims are quoted in some optometric textbooks their content varies significantly and no direct research evidence was available to support their use. Accordingly in chapters 2 and 3, the uses of several potential prescribing rules were investigated in the UK optometric profession. Our results indicated that the subjective refraction result exerted a strong hold on the prescribing outcome with 40-85% of optometrists prescribing the subjective result in a variety of scenarios. The finding that after 40 years qualified, experienced optometrists were three times more likely to suggest a partial prescription was an important discovery that provides significant support for the prescribing rules suggested by various authors. It would also appear from the results of the retrospective evaluation of the 'if it ain't broke, don't fix it' clinical maxim in Chapter 4 that spectacle dissatisfaction rates could be reduced by between 22 to 42% depending on how strictly the maxim is interpreted by the practitioner. Certainly an 'if it ain't broke, don't fix it much' maxim was suggested as being particularly appropriate. Chapter 5 included a reanalysis of previously published data that found no change in falls rate after cataract surgery to investigate any influence of refractive correction change and /or visual acuity change on falls rate. Unfortunately these data were not sufficiently powered to provide significant results. In chapter 6, a spectacle adaptation questionnaire (SAQ) was developed and validated using Rasch analysis. Initial studies found no differences in SAQ with gender or age.

Aim: The aim of this study was to examine if student nurse participation in root cause analysis has the potential to reduce harm to patients from medication errors by increasing student nurse sensitivity to signal and responder bias. Background: Schools of nursing have traditionally relied on strategies that focus on individual characteristics and responsibility to prevent harm to patients. The modern patient safety movement encourages utilization of systems theory strategies like Root Cause Analysis (RCA). The Patient Risk Detection Theory (Despins, Scott-Cawiezell, & Rouder, 2010) supports the use of nurse training to reduce harm to patients. Method. Descriptive and inferential analyses of the demographic and major study variables were conducted. Validity and reliability assessments for the instruments were performed. The Safe Administration of Medications-Revised Scale (Bravo, 2014) was used to measure sensitivity to signal. The Safety Attitudes Questionnaire (SAQ; Sexton et al., 2006) was used to assess responder bias; this was the first use of this instrument with nursing students. Results: The sample consisted of 125 senior-level nursing students from three universities in the southeastern United States. The SAQ was found to be a valid and reliable test of safety attitudes in nursing students. Further support for the validity and reliability of the SAM-R was provided. A significant difference in safety climate between schools was observed. There were no differences detected between the variables. Conclusion: The results of this study provide support for the use of the SAQ and the SAM-R to further test the PRDT, and to explore methods to improve nursing student ability to administer medications safely.

The current global changes and regulations in sustainability have a direct impact on suppliers to the automotive industry. Therefore, it is crucial for suppliers to the automotive industry to proactively monitor developments to avoid risking their competitiveness. This involves an increased focus on documentation and compliance with sustainability policies and certifications. Company X is a family-owned company located in Gnosjö, operating for nearly 80 years and supplying products to the automotive industry, among other sectors. The company specializes in industrial work and focuses on machining (turning and milling). To remain competitive and, above all, relevant for at least another 80 years, they strive for continuous development to meet customer demands. The guiding philosophy is to operate within the ”Global Automotive Sustainability Guiding Principles”, which clarify the automotive industry ́s expectations regarding sustainability efforts from their suppliers. In late 2022, Drive Sustainability, responsible for creating and maintaining the Self-Assessment Questionnaire (SAQ), raised the requirements from SAQ 4.0 to SAQ 5.0. The consequence of not being approved before June 2023 is the inability to initiate new business as a supplier to Scania. The thesis was conducted at Company X with the aim of investigating what is required for Business X to upgrade from SAQ 4.0 to SAQ 5.0. This involved identifying any gaps in the company’s environmental and quality management systems in relation to the SAQ portal. The project also aimed to examine whether the current quality and environmental management system needs adjustment to better reflect data in the SAQ portal. The main task of the author was to explore possible solutions to help Company X and other SMEs implement the SAQ process in a resource-efficient manner. To achieve the study ́s purpose, an analysis of the documentation in the company ́s environmental and quality management systems in relation to the SAQ portal was conducted. This analysis was used to identify the resources required to meet the requirements in the SAQ. Based on the formulated research questions, gaps in the company ́s environmental and quality management systems were identified concerning the SAQ portal. Additionally, proposals and arguments were provided for adjustments to the current management system. The result of the thesis was that Company X acted on the suggestions and was approved in SAQ 5.0 with a fulfillment rate of 81%, compared to the previous score 79% in SAQ 4.0. The model presented in the analysis of the SAQ scoring system can also be utilized by other SMEs to implement the SAQ process in a resource-efficient manner.
