Bakgrund Vistelsetiden på akutmottagningen på Centralsjukhuset i Kristianstad har studerats och en skillnad identifierades där män i större utsträckning än kvinnor hade en vistelsetid kortare än fyra timmar. Ingen direkt orsak till skillnaden i vistelsetid kunde urskiljas. Det identifierade fenomenet valdes att bearbetas med genus som begrepp. Syfte Syftet med studien var att undersöka orsaken till varför det är en skillnad i vistelsetid mellan män och kvinnor på akutmottagningen. Metod Metod för datainsamling var kvalitativ intervju. Informanter valdes strategiskt utifrån kriteriet att de arbetade på en akutmottagning, och bestod av olika yrkesprofessioner, kön samt yrkeserfarenhet. Två olika sjukhus i södra Sverige deltog i studien. Totalt inkluderas nio informanter. Semistrukturerade enskilda intervjuer med öppna frågor genomfördes och insamlad data analyserades genom kvalitativ innehållsanalys enligt Graneheim och Lundman. Resultat Skillnaden i vistelsetid på akutmottagningen upplevdes bero på att kvinnor söker med ospecifika och diffusa symtom/orsaker eller oro, sökorsaker som upplevdes mer tidskrävande. I motsatts upplevdes män söka med konkreta/specifika symtom eller allvarlig sjukdom/skada, sökorsaker som upplevdes mindre tidskrävande. Skillnaden upplevdes även bero på när i sjukdomsförloppet patienten söker, sociokulturella faktorer, biologiska könsskillnader samt olika kommunikationsmönster. Slutsatser Skillnaden i män respektive kvinnors vistelsetid på akutmottagningen upplevdes inte bero på vårdpersonalens medvetna handlingar, utan på patientens sökorsak, vald tidpunkt för besök, biologiska faktorer, sociokulturella faktorer samt kommunikativa faktorer. / Background The length of stay in the emergency department at Central Hospital in Kristianstad has been studied and a difference was identified where men more often than women had a length of stay less than four hours. No direct reason for the difference in length of stay could be discerned. This identified phenomenon has been selected to be analyzed with gender as a cause of inequality. Aim The aim of this study was to investigate the reason why there is a difference in length of stay between men and women in the Emergency Department. Methods Method of data collection was qualitative interviews. Informants were chosen strategically based on the criterion that they work in an Emergency Department, consist of various professions, sex and work experience. Two different hospitals in southern Sweden participated in the study. It included in total nine informants. Semi-structured individual interviews with open-ended questions were conducted, and the collected data were analyzed through qualitative content analysis by Graneheim and Lundman. Results The difference in length of stay in the emergency department was experienced due to women seeking with non-specific and diffuses symptoms/cause or concerns, reason to seek experienced more time consuming. Contrarily experienced men seek with concrete/specific symptoms or serious illness/injury, reason to seek experienced less time consuming. The difference was experienced also depend on when in the course of the disease the patient is seeking, socio-cultural factors, biological gender differences, and different communication patterns. Conclusions The difference in men and women's length of stay in the Emergency Department is experienced not to depend on nursing staff aware actions, but on the patient´s reason to seek, the selected time for visit, biological factors, socio-cultural factors, as well as communicative elements.
