Introduktion Sjukvården har som mål att bota, lindra och hjälpa, ändå finns det bevis som pekar på att sjukvården inte är så säker som den borde vara. Detta medför en reducerad patientsäkerhet. Vid granskning av tidigare incidenter inom intensivvården kunde, i cirka 50 % av fallen, brister i icke-tekniska färdigheter (Non Technical Skills, NTS) hos sjukvårdspersonalen tillskrivas som orsak. Då sjukvårdspersonal, främst sjuksköterskor, ofta utgör den sista, och ibland den enda, försvarslinjen mot patienten är det av vikt att träna NTS. Detta då en hög patientsäkerhet eftersträvas inom sjukvården.

ABSTRACT Introduction: During the past 40 years the ambulance service in Sweden has evolved from mainly being a source of transport to today?s high-tech caring facilities that enable qualified care to start already in the patient?s home. This first level of care is now provided by registered nurses and registered nurses with specialist training in pre hospital care.At the same time as the care provided is becoming more advanced, results from studies demonstrate that the amount of dispatches to patients that lack the need for ambulance care and transport is increasing. Nurses in pre-hospital care possess the knowledge, training and authority to perform an initial assessment of patients and also treat patients according to local and national guidelines. After the treatment it would sometimes be possible for the patients to remain at home without having to use ambulance transport to an emergency department or in other cases find other means of transport to hospital.

The idea with constructions made out of prefabricated elements is that it should be quick and easy to build as the demands for lower production costs, increased profitability and shorter production times are constantly increasing. High accuracy in measurements and well-balanced tolerances is required to achieve this. The fact that the concrete-elements doesn?t fit and that damage occurs during assembly is a highly topical issue even though we now have methods and systems that make this high-intensity construction possible. Through this report we want to highlight the problems that cause the dimensional and tolerance problems and give suggestions on how to come to terms with these.
