- Introduction: Studies examining the factors linked to survival after out of hospital cardiac arrest (OHCA) have either aimed to describe the characteristics and outcomes of OHCA in different parts of the world, or focused on certain factors and whether they were associated with survival. Unfortunately, this approach does not measure how strong each factor is in predicting survival after OHCA. Aim: To investigate the relative importance of 16 well-recognized factors in OHCA at the time point of ambulance arrival, and before any interventions or medications were given, by using a machine learning approach that implies building models directly from the data, and arranging those factors in order of importance in predicting survival. Methods: Using a data-driven approach with a machine learning algorithm, we studied the relative importance of 16 factors assessed during the pre-hospital phase of OHCA We examined 45,000 cases of OHCA between 2008 and 2016. Results: Overall, the top five factors to predict survival in order of importance were: initial rhythm, age, early Cardiopulmonary Resuscitation (CPR, time to CPR and CPR before arrival of EMS), time from EMS dispatch until EMS arrival, and place of cardiac arrest The largest difference in importance was noted between initial rhythm and the remaining predictors. A number of factors, including time of arrest and sex were of little importance. Conclusion: Using machine learning, we confirm that the most important predictor of survival in OHCA is initial rhythm, followed by age, time to start of CPR, EMS response time and place of OHCA. Several factors traditionally viewed as important e.g. sex, were of little importance.

Samspel i kommunal administration : Lagspel, dragkamp eller hierarki?
- 2023
-
Bok (refereegranskat)abstract
- Den här boken handlar om chefer, experter och stödfunktioner i kommuner - och om deras administrativa arbete. Den kommunala sektorns administration har på några decennier förändrats genomgripande, både vad gäller omfattning, arbetsinnehåll och styrka. Inom flera områden har roller professionaliserats, och mer kraft och resurser har lagts på att styra organisationen med bakgrund i krav på granskningsbarhet, kommunövergripande policyer och mätbar måluppfyllelse. Det har kommit att påverka hela den kommunala organisationen. I den här boken redogör vi för hur samspel mellan olika administrativa funktioner (såsom chefer, stödverksamhet och staber) ser ut och förändras. Vi diskuterar också hur goda samspel kan se ut, och vad som krävs för att åstadkomma sådana. Boken riktar sig till alla med intresse för organisatoriskt samspel mellan chefer, experter av olika slag och servicefunktioner i dagens kommunala värld. Särskilt riktar den sig till studenter som läser utbildningar inom personal- och arbetsvetenskap, organisation och ledarskap, och offentlig förvaltning, samt till dem som arbetar med ledning och administration i kommuner.

Tidskriftsartikel (refereegranskat)abstract
- Artikeln handlar om den betydelse existentiell mening har för utvecklingen av ett ekonomiskt, socialt och ekologiskt hållbart alternativsamhälle på landsbygden. I artikeln analyseras 15 individers berättelser om konkreta praktiker och gemensamma insatser i formandet av en existentiellt meningsfull vardag på en plats med cirkulär ekonomi, självförsörjning och arbetskritiska attityder. Analysen inramas av ett existenssociologiskt perspektiv och Becks tanke om ”frihetens barn”, som i en andra modernitet försöker att ta vara på de möjligheter som kan uppstå i ett samhälle som i övrigt mest erbjuder risker och osäkerhet. Genom att utveckla ett ”livspolitiskt” förhållningssätt, bortom konsumtionssamhällets överflöd och arbetssamhällets plikter, vill intervjupersonerna både uppnå ett meningsfullt liv i nuet och bygga ett hållbart lokalsamhälle där resurser tillvaratas för kommande generationer. Målet är att till skillnad från upplevelsen av meningslöshet i det kapitalistiska arbetssamhället skapa existentiell mening på en plats där de kan bestämma över sin egen tid och finna kollektiva lösningar på individuella problem. Strävan efter att etablera ett sådant postkapitalistiskt samhälle medför dock även dilemman och interna konflikter kring organiserings- och finansieringsmöjligheter.

- BACKGROUND: The epidemiology and outcome after out-of-hospital cardiac arrest (OHCA) varies across Europe. Following on from EuReCa ONE, the aim of this study was to further explore the incidence of and outcomes from OHCA in Europe and to improve understanding of the role of the bystander.METHODS: This prospective, multicentre study involved the collection of registry-based data over a three-month period (1st October 2017 to 31st December 2017). The core study dataset complied with the Utstein-style. Primary outcomes were return of spontaneous circulation (ROSC) and survival to hospital admission. Secondary outcome was survival to hospital discharge.RESULTS: All 28 countries provided data, covering a total population of 178,879,118. A total of 37,054 OHCA were confirmed, with CPR being started in 25,171 cases. The bystander cardiopulmonary resuscitation (CPR) rate ranged from 13% to 82% between countries (average: 58%). In one third of cases (33%) ROSC was achieved and 8% of patients were discharged from hospital alive. Survival to hospital discharge was higher in patients when a bystander performed CPR with ventilations, compared to compression-only CPR (14% vs. 8% respectively).CONCLUSION: In addition to increasing our understanding of the role of bystander CPR within Europe, EuReCa TWO has confirmed large variation in OHCA incidence, characteristics and outcome, and highlighted the extent to which OHCA is a public health burden across Europe. Unexplained variation remains and the EuReCa network has a continuing role to play in improving the quality management of resuscitation.

Teaching for a monolingual school? (In)visibility of multilingual perspectives in Swedish teacher education
- 2022

Tidskriftsartikel (refereegranskat)abstract
- This article analyses the knowledge about linguistic and cultural diversity that is delineated in the syllabi of teacher education programmes for pre-, primary and secondary schools at two Swedish universities. A quantitative search for 14 chosen keywords preceded a closer analysis of the concepts *language* and *cultur*, when using truncation, in 192 syllabi. This showed that linguistic diversity was to a certain extent evident, mainly through the subjects Swedish and English, while for one university cultural diversity was mainly identified in the syllabi of Educational Work and English. If knowledge about linguistic and cultural diversity is limited to language subjects, and to some extent to pre-school and earlier school years, the risk is high that student teachers are not prepared to support equity in education for multilingual and non-dominant groups. Thus, we find that students studying the current Swedish teacher education programme are unlikely to be well equipped to meet the challenges related to creating equal educational opportunities for students in situations of linguistic and cultural diversity.

Tidskriftsartikel (refereegranskat)abstract
- Background The ambulance response time in out-of-hospital cardiac arrest (OHCA) has doubled over the past 30 years in Sweden. At the same time, the chances of surviving an OHCA have increased substantially. A correct understanding of the effect of ambulance response time on the outcome after OHCA is fundamental for further advancement in cardiac arrest care. Methods and ResultsWe used data from the SRCR (Swedish Registry of Cardiopulmonary Resuscitation) to determine the effect of ambulance response time on 30-day survival after OHCA. We included 20 420 cases of OHCA occurring in Sweden between 2008 and 2017. Survival to 30 days was our primary outcome. Stratification and multiple logistic regression were used to control for confounding variables. In a model adjusted for age, sex, calendar year, and place of collapse, survival to 30 days is presented for 4 different groups of emergency medical services (EMS)-crew response time: 0 to 6 minutes, 7 to 9 minutes, 10 to 15 minutes, and >15 minutes. Survival to 30 days after a witnessed OHCA decreased as ambulance response time increased. For EMS response times of >10 minutes, the overall survival among those receiving cardiopulmonary resuscitation before EMS arrival was slightly higher than survival for the sub-group of patients treated with compressions-only cardiopulmonary resuscitation.ConclusionsSurvival to 30 days after a witnessed OHCA decreases as ambulance response times increase. This correlation was seen independently of initial rhythm and whether cardiopulmonary resuscitation was performed before EMS-crew arrival. Shortening EMS response times is likely to be a fast and effective way of increasing survival in OHCA.
