Background: When an individual is cared for in a hospital, which is a new and unknown environment, this can create feelings of uncertainty and insecurity for some. Insecurity can lead to a feeling of pressure and makes the caring more difficult. This can therefore worsen the recovery for the patient. Aim: The aim of this study was to illuminate the patient's perceived experience of safety at hospital. Method: A literature based study was done based on ten qualitative articles among men- and women at hospital. Result: The study showed that the feeling of safety could be experienced when the patient felt confirmed, the patient feels involved in their own care and when nursing staff cares for the patient. To felt safe is also found in how patients perceive their environment through the hospital's physical and social environment. The result of the articles were presented in two main themes; the meaning of the caring relationship and presence of others. Conclusion: There was several factors that contribute to the feeling of safety for the patient in hospital care. Patients’ feelings of safety can be experienced by acts such as to be confirmed by the care giving staff, the patient's opportunity to be involved and when the patient feels cared about. / Examensarbetet har för avsikt att belysa patienters upplevda erfarenhet av trygghet vid sjukhusvård. Trygghet är ett filosofiskt begrepp med olika innebörder och upplevs olika från individ till individ. Trygghet kan delas in i både inre och yttre trygghet där den inre tryggheten skapas av positiva minnen från barndomen såsom minnen från en vacker sommardag. Inre trygghet kan också skapas i vuxen ålder av positiva erfarenheter såsom bli väl bemött och omhändertagen under sjukhusvården. Yttre trygghet kan ses såsom miljön patienten har runt sig. Detta examensarbete benämner det som den sociala och fysiska miljön. Den sociala miljön skapas av närvaro av närstående, andra patienter och vårdpersonal. Den fysiska miljön handlar om hur sjukhusmiljön är utformad och påverkar den sociala miljön. Resultatet från de tio vetenskapliga artiklarna inkluderade i examensarbetet visar att upplevelse av trygghet är associerad med upplevelsen av vårdrelationen och relationen till andra signifikanta personer. Det framkommer att upplevelse av trygghet påverkas av graden av delaktighet i vården, relationen till personalen och närstående samt den fysiska vårdmiljön.

This is a project-based thesis focusing on the investigation of topics related to human newborns and the factors found in their surrounding environment that need to be assessed so as to provide them with a feeling comfort. The objective is to boost their emotional development by the means of light in a close relation to sound so as to provide them with a type of intelligence allowing them to normally interact within a society during their adult life, reassuring social equality and eliminating potential social exclusion due to unexpected behaviours. After researching topics to have a better understanding of the newborn baby and its enclosing environment, a luminaire design solution -functioning with a reactive scheme performed with integrated sound sensors- provided further results to the main topic investigation. The conceptual scheme for the product development was inspired by the connection between the newborn and their life-giver, closely linked to the cross-modality of sensory development before and after birth. Additional results were obtained with light measurement assessments and a parent survey targeting both the intended light quality subjective evaluations and the marketing strength of the designed product. This survey was used -along with other means- as a design evaluation tool at the final stage of the design process. Potential further improvements as well as considerations for a distinct spatial application are discussed in the final part of the thesis. The sustainability aspect covered within this degree project is closely linked to good physical and mental health aspects, clean energy use and efficiency achieved by the integration of input sound sensors and controls, and conscious production and consumption by the proposal of low global footprint materials for the luminaire design. In the conclusions, an overall summary of the thesis outcomes is presented and further research is proposed regarding both the main topic investigation as well as a greater user category that can be related to the light metric assessments that were carried out for this research.
