Abstract Background Working in the emergency medical service (EMS) can be extremely varying and sometimes physically and psychologically demanding. Being new in this context can be a great challenge. This study aim to describe what ambulance nurses consider to be important support during the first year in the EMS. Methods Three hundred and eighty-nine eligible participants that had graduated from the prehospital emergency care program were identified via university registrations office in Sweden. The eligible participants received a study specific questionnaire via mail consisting of 70 statements about support during the first year. The perceived importance of each statement were graded on a 7-point Likert scale. The gradings were analysed using descriptive statistics and frequencies, mean and SD were calculated. Results Two hundred and thirty questionnaires were returned fully completed, giving a response rate of 59%. Fourteen statements regarding desirable support were rated with mean values > 6.00 and SD < 1.00 and considered as being the most important during the first year in the EMS. The important supports regarded; colleagues and work environment, management and organisation, experience-based knowledge, introduction period, practical support, and theoretical support. Most statements regarded culture and climate and the way the newcomers wanted to be treated. Conclusion It was concluded that an important way to support newcomers in the EMS is to treat them ‘nice’. This can be achieved by creating an open climate and a welcoming culture where the new professionals feel trusted and treated with respect, created ways to work structurally, have applicable medical guidelines, and for newcomers to receive feedback on their actions.
