Background: Survival after out-of-hospital cardiac arrest (OHCA) is still low. For every minute without resuscitation the likelihood of survival decreases.One critical step is initiation of immediate, high quality cardiopulmonary resuscitation (CPR). The aim of this subgroup analysis of data collected for the European Registry of Cardiac Arrest Study number 2 (EuReCa TWO) was to investigate the association between OHCA survival and two types of bystander CPR namely: chest compression only CPR (CConly) and CPR with chest compressions and ventilations (FullCPR).Method: In this subgroup analysis of EuReCa TWO, all patients who received bystander CPR were included. Outcomes were return of spontaneous circulation and survival to 30-days or hospital discharge. A multilevel binary logistic regression analysis with survival as the dependent variable was performed.Results: A total of 5884 patients were included in the analysis, varying between countries from 21 to 1444. Survival was 320 (8%) in the CConly group and 174 (13%) in the FullCPR group. After adjustment for age, sex, location, rhythm, cause, time to scene, witnessed collapse and country, patients who received FullCPR had a significantly higher survival rate when compared to those who received CConly (adjusted odds ration 1.46, 95% confidence interval 1.17À1.83). Conclusion:In this analysis, FullCPR was associated with higher survival compared to CConly. Guidelines should continue to emphasise the importance of compressions and ventilations during resuscitation for patients who suffer OHCA and CPR courses should continue to teach both.

Many students in vocational education and training (VET) have difficulties with reading and writing. To date, there is little research on whether and how the development of VET students’ writing skills may benefit from teaching approaches that integrate reading and writing. This study reports results from a semester-long intervention study conducted in Switzerland in 2018/19 (N = 285) in which we investigated the impact of a scenario-based integration of reading-to-write-tasks on the development of VET students’ text quality. In the approach, problem-solving processes are set in motion by scenarios representing real- or work-life situations. Reading-to-write tasks form part of the student-initiated problem-solving process, and result in situated argumentative writing. A small experimental intervention effect was found where text quality developed significantly better in the experimental group than in a matched control group (F1,178 = 7.40, p < .01, Cohen’s f = 0.20), as measured in a writing test before and after exposure to the teaching method. Outcomes suggest tangible benefits may result when applying this approach to literacy education in VET, particularly for academically weaker students. We discuss the consequences and implications of these findings, as well as open questions to be addressed by further research.
