The scientific documentation of prehospital emergency care in Sweden is slowly expanding. The first thesis on the value of a mobile coronary care unit was defended in 1982. Since then, at least 106 theses have been defended at 15 educational institutes in Sweden. The theses can be divided into nine different themes, of which acute disease and prognostic factors (n = 30) is the most common, followed in order of frequency by caring, assessment and decision (n = 18), patient and next of kin perspective (n = 14), trauma (n = 1 1), competence, learning, and education (n = 10), care needs, cooperation, and prioritization (n = 10), disaster (n = 7), workers' health and environment (n = 3), and ethics and values (n = 3). The University of Gothenburg had the highest number of theses defended (n = 28), followed by the Karolinska Institute (n = 24) and the University of Umeå (n = 10). The theses were written by 64 nurses, 36 physicians, two public health specialists, one physiotherapist, one priest, one social worker, and one statistician.
