Hvordan velger AMK-operatøren sin respons ved hendelser med mulig alvorlig skade? En kvalitativ analyse basert på gjennomgang av eksisterende aktuell litteratur
(Master thesis; Mastergradsoppgave, 2023-05-24)En rekke studier de senere år antyder at kjønn, alder og geografi er av betydning for håndtering av pasienter med mistenkt alvorlig skade. En ser at menn får mer avansert prehospital behandling, transporteres oftere til høyere omsorgsnivå og møtes oftere av traumeteam, sammenlignet med kvinner. Dette sees også når en justerer for skademekanisme. AMK-operatøren spiller en viktig rolle i ... -
