Learning Outcome After Different Combinations of Seven Learning Activities in Basic Life Support on Laypersons in Workplaces: a Cluster Randomised, Controlled Trial.

Background: The goal for laypersons after training in basic life support (BLS) is to act effectively in an out-of-hospital cardiac arrest situation. However, it is still unclear whether BLS training targeting laypersons at workplaces is optimal or whether other effective learning activities are possible.

Aim: The primary aim was to evaluate whether there were other modes of BLS training that improved learning outcome as compared with a control group, i.

Cardiac arrest in COVID-19: characteristics and outcomes of in- and out-of-hospital cardiac arrest. A report from the Swedish Registry for Cardiopulmonary Resuscitation.

Aim: To study the characteristics and outcome among cardiac arrest cases with COVID-19 and differences between the pre-pandemic and the pandemic period in out-of-hospital cardiac arrest (OHCA) and in-hospital cardiac arrest (IHCA).

Method And Results: We included all patients reported to the Swedish Registry for Cardiopulmonary Resuscitation from 1 January to 20 July 2020. We defined 16 March 2020 as the start of the pandemic.

Supplementary dataset to self-learning training compared with instructor-led training in basic life support.

In this article, we present supplementary data to the article entitled "Self-learning training versus instructor-led training in basic life support: a cluster randomised trial" [1]. In three supplementary files, we present the informed consent of the included participants, the modified instrument to calculate the total score for practical skills called "the Cardiff Test of basic life support and automated external defibrillation" and the questionnaire to obtain background factors, theoretical knowledge, self-assessed knowledge and confidence and willingness to act, distributed directly after training and six months after training. The results of comparisons between "directly after intervention" and "six months after intervention", for each training group separately, are presented in three tables.

Out-of-hospital cardiac arrest in the elderly: A large-scale population-based study.

Background: There is little information on elderly people who suffer from out-of-hospital cardiac arrest (OHCA).

Aim: To determine 30-day mortality and neurological outcome in elderly patients with OHCA.

Methods: OHCA patients ≥ 70 years of age who were registered in the Swedish Cardiopulmonary Resuscitation Register between 1990 and 2013 were included and divided into three age categories (70-79, 80-89, and ≥ 90 years).

Early cardiopulmonary resuscitation in out-of-hospital cardiac arrest.

Background: Three million people in Sweden are trained in cardiopulmonary resuscitation (CPR). Whether this training increases the frequency of bystander CPR or the survival rate among persons who have out-of-hospital cardiac arrests has been questioned.

Methods: We analyzed a total of 30,381 out-of-hospital cardiac arrests witnessed in Sweden from January 1, 1990, through December 31, 2011, to determine whether CPR was performed before the arrival of emergency medical services (EMS) and whether early CPR was correlated with survival.

Aim: To describe presence of risk indicators of recurrence 6 months after hospitalisation due to coronary artery disease at a university clinic.

Methods: The presence of risk indicators, including tobacco use, lipid levels, blood pressure and glucometabolic status, including 24-hour blood pressure monitoring and an oral glucose-tolerance test, was analysed.

Results: Of 1465 patients who were screened, 402 took part in the survey (50% previous myocardial infarction and 50% angina pectoris).

Survival in out-of-hospital cardiac arrest before and after use of advanced postresuscitation care: a survey focusing on incidence, patient characteristics, survival, and estimated cerebral function after postresuscitation care.

Background: Knowledge of the epidemiology of postresuscitation care is insufficient. We describe the epidemiology of postresuscitation care in a community from a 26-year perspective, focusing on incidence, patient characteristics, survival, and estimated cerebral function in relation to intensified postresuscitation care and initial arrhythmia.

Methods: The study included patients with out-of-hospital cardiac arrest (OHCA) who were brought alive to a hospital ward in Göteborg, Sweden, between 1980 and 2006.

Cardiac arrest outside and inside hospital in a community: mechanisms behind the differences in outcome and outcome in relation to time of arrest.

Background: The aim was to compare characteristics and outcome after cardiac arrest where cardiopulmonary resuscitation was attempted outside and inside hospital over 12 years.

Methods: All out-of-hospital cardiac arrests (OHCAs) in Göteborg between 1994 and 2006 and all in-hospital cardiac arrests (IHCAs) in 1 of the city's 2 hospitals for whom the rescue team was called between 1994 and 2006 were included in the survey.

Results: The study included 2,984 cases of OHCA and 1,478 cases of IHCA.

Improved survival after out-of-hospital cardiac arrest is associated with an increase in proportion of emergency crew--witnessed cases and bystander cardiopulmonary resuscitation.

Background: Out-of-hospital cardiac arrest (OHCA) is a major public health problem. We sought to describe changes in 1-month survival after OHCA in patients given cardiopulmonary resuscitation (CPR) during the last 14 years in Sweden.

Methods And Results: All patients experiencing OHCA in whom CPR was attempted between 1992 and 2005 and who were reported to the Swedish Cardiac Arrest Register were included in the study.

Time trends in long-term mortality after out-of-hospital cardiac arrest, 1980 to 1998, and predictors for death.

Background: We studied time trends in long-term survival after out-of-hospital cardiac arrest (OHCA) for patient characteristics and described predictors for death after discharge. Because long-term prognosis among patients with coronary heart disease has improved in the last decades, we hypothesized that the prognosis after OHCA would improve with time.

Methods: We analyzed data that were prospectively collected from all patients discharged from the hospital after OHCA in the community of Göteborg, Sweden, from 1980 to 1998 and divided the data into 2 time periods, 1980 to 1991 and 1991 to1998, with an equal number of patients.
