Bakgrund: Interhospitala transporter ökar årligen inom Sverige. För att en interhospital transport skall utföras med god vårdkvalitet ställs höga krav på samarbete mellan de olika professionerna. Ett väl fungerande team underlättar arbetet och leder till ökad trygghet hos personalen vilket troligen kommer att påverka den vård patienten får. Det finns emellertid begränsad kunskap om hur teamarbetet fungerar vid interhospitala transporter och vad personalen har för erfarenhet av det.   Syfte: Syftet med studien var att beskriva anestesi- och ambulanssjuksköterskors erfarenheter av teamarbetet vid interhospitala transporter.   Metod: Studien utfördes med en kvalitativ metod där semistrukturerade intervjuer genomfördes med tolv anestesi- och ambulanssjuksköterskor vid två olika regioner i södra Sverige under våren 2017. Analysen företogs med en kvalitativ innehållsanalys enligt Graneheim och Lundman (2004).   Resultat: Resultatet redovisas i fyra kategorier med underkategorier. Erfarenheterna tyder på ett överlag välfungerande teamarbete vid de interhospitala transporterna. Kommunikation, ansvarsfördelning och tidigare erfarenheter uppfattades påverka samarbetet samt den vård som patienten fick. Relationerna i teamet samt attityder hos teammedlemmarna innebär en utmaning för synergin i teamet.   Slutsats: Ett välfungerande teamarbete utgörs av tydlig kommunikation, relationerna i teamet samt grundlig kompetens vilket framkallar en trygghet i teamet. Erfarenheterna av samarbetet vid interhospitala transporter är bra samtidigt som det finns ett behov och en vilja till förbättring. / Background : The interhospitala transports of intensive care patients is increasing every year in Sweden. To make sure that the transport between the various units are- performed to the highest possible level of care it is vital that a high standard of co-operation is performed with all professionals involved. Well organized teamwork eases the workload and helps to give a feeling of security with all staff involved which is then likely to positively affect the care of the patient in focus. However there is still a limited knowledge about how a well functioned teamwork is interpreted between all parts involved in transportation of intensive care patients. Purpose: The purpose with this study was to describe the Nurse anesthetists and Ambulance nurses experiences of teamwork at interhospitala transports. Method: This study was implemented with a qualitative method where semi-structured interviews took place with 12 Nurse anesthetists or Ambulance nurses in two different regions in the south of Sweden during the spring of 2017. The analysis was completed with a qualitative content analysis according to Graneheim and Lundman (2004). Result: The result is presented in four categories. The experiences of those involved gave an interpretation of a mainly well-functioning teamwork. However communication, division of responsibilities and competence are main factors with recurring issues which was perceived to affect the cooperation of all professions involved and of course the treatment that the patients receive. The relations in the team as well as the attitudes of the team members funds challenges for the synergy in the team. Conclusion : A well functioning teamwork is built from clear communication, relations in the team and thorough expertise which will lead to a feeling of safety in the team. The experiences of the cooperation in interhospital transports are good, at the same time as there is a need and a will to make improvements.
