Content validation of the HeartRunner questionnaire to volunteer responders dispatched to out-of-hospital cardiac arrests: A qualitative study.

Aim: To increase survival after out-of-hospital cardiac arrest (OHCA) in Denmark, volunteer responders are activated through a smartphone application (HeartRunner app) to quickly locate an automated external defibrillator (AED) and assist with cardiopulmonary resuscitation (CPR). All dispatched volunteer responders who have been activated by the app receive a follow-up questionnaire to evaluate their participation in the programme. The content of the questionnaire has never been thoroughly evaluated.

Volunteer responder provision of support to relatives of out-of-hospital cardiac arrest patients: a qualitative study.

Objectives: Smartphone dispatch of volunteer responders for out-of-hospital cardiac arrest (OHCA) is implemented worldwide. While basic life support courses prepare participants to provide CPR, the courses rarely address the possibility of meeting a family member or relative in crisis. This study aimed to examine volunteer responders' provision of support to relatives of cardiac arrest patients and how relatives experienced the interaction with volunteer responders.

Does time heal fatigue, psychological, cognitive and disability problems in people who experience an out-of-hospital cardiac arrest? Results from the DANCAS survey study.

Aims: Out-of-hospital cardiac arrest (OHCA) survivors may suffer short-term fatigue, psychological, cognitive and disability problems, but we lack information on the proportion of survivors with these problems in the long-term. Hence, we investigated these problems in survivors 1-5 years post-OHCA and whether the results are different at different time points post-OHCA.

Methods: All adults who survived an OHCA in Denmark from 2016 to 2019 were identified using the Danish Cardiac Arrest Registry and invited to participate in a survey between October 2020 and March 2021.

Association of patient-reported psychosocial healthcare and risk of readmissions and mortality in patients with ischemic heart disease: A population-based cohort study.

Objective: Psychosocial risk factors are common in patients with ischemic heart disease (IHD) and linked to poor prognosis. Psychosocial healthcare is recommended in international guidelines and has demonstrated positive effects, primarily on psychosocial symptoms. We examined the association between patient-reported psychosocial healthcare and hospital readmissions and mortality in patients with IHD.

Perception of pharmacological prevention and subsequent non-adherence to medication in patients with ischaemic heart disease: a population-based cohort study.

Objective: A patient-focused approach is advocated to embody risk of non-adherence to medication and subsequent adverse clinical outcomes following ischaemic heart disease (IHD). This study aimed to explore how patient perceived information on pharmacological prevention was associated with subsequent non-adherence to medication (measured by non-initiation, non-implementation and non-persistence) in patients with incident IHD.

Design: Cohort study.

Cardiac rehabilitation for patients with heart failure: association with readmission and mortality risk.

Aims: To examine the temporal trends and factors associated with national cardiac rehabilitation (CR) referral and compare the risk of hospital readmission and mortality in those referred for CR versus no referral.

Methods And Results: This cohort study includes all adult patients alive 120 days from incident heart failure (HF) identified by the Danish Heart Failure Registry (n = 33 257) between 2010 and 2018. Multivariable logistic regression models were used to assess the association between CR referral and patient factors and acute all-cause hospital readmission and mortality at 1 year following HF admission.

Immediate psychological impact on citizen responders dispatched through a mobile application to out-of-hospital cardiac arrests.

Background: Activating citizen responders may increase survival after out-of-hospital cardiac arrest (OHCA) but could induce significant psychological impact on the citizen responders. We examined psychological impact among citizen responders within the first days following resuscitation attempt.

Methods And Results: A mobile phone application to activate citizen responders to perform cardiopulmonary resuscitation (CPR) was implemented in the Capital Region of Denmark.

Long-term physical and psychological outcomes after out-of-hospital cardiac arrest-protocol for a national cross-sectional survey of survivors and their relatives (the DANCAS survey).

Introduction: The number of out-of-hospital cardiac arrest (OHCA) survivors is increasing. However, there remains limited knowledge on the long-term physical and psychological problems suffered by survivors and their relatives. The aims of the DANCAS (DANish cardiac arrest survivorship) survey are to describe the prevalence of physical and psychological problems, identify predictors associated with suffering them and to determine unmet rehabilitation needs in order to make recommendations on the timing and content of future rehabilitation interventions.

What are the prevalence and predictors of psychosocial healthcare among patients with heart disease? A nationwide population-based cohort study.

Objectives: Psychosocial healthcare is recommended, but little is known about how patients perceive the level of care and whether subgroups of patients experience less psychosocial healthcare than others. We examined the prevalence of patient-reported psychosocial healthcare and factors predicting patient-reported lack of psychosocial healthcare among patients with heart disease.

Design: A cohort study.

How to measure experiences of healthcare quality in Denmark among patients with heart disease? The development and psychometric evaluation of a patient-reported instrument.

Objective: Measuring the quality of care as experienced by patients is increasingly recognised as a way of improving healthcare services. However, disease-specific measures that take the patient journey into account are needed. This paper presents the development of such a measure for patients with heart disease and details the psychometric evaluation.

The association between supportive relatives and lower occurrence of anxiety and depression in heart patients: Results from a nationwide survey.

Background: Approximately 30-40% of heart patients develop anxiety and/or depression, which might influence recovery and long-term survival. Research has suggested that support from relatives may decrease anxiety and depression among heart patients; however, the results are inconsistent and often based on small study populations.

Aim: The paper aimed to investigate the association between having supportive relatives and the occurrence of anxiety and depression in heart patients.

Cardiopulmonary Resuscitation Training in Schools Following 8 Years of Mandating Legislation in Denmark: A Nationwide Survey.

Background: School cardiopulmonary resuscitation (CPR) training has become mandatory in many countries, but whether legislation has translated into implementation of CPR training is largely unknown. We assessed CPR training of students following 8 years of legislative mandates in Denmark.

Methods And Results: A nationwide cross-sectional survey of Danish school leadership (n=1240) and ninth-grade homeroom teachers (n=1381) was carried out for school year 2013-2014.

Lay Bystanders' Perspectives on What Facilitates Cardiopulmonary Resuscitation and Use of Automated External Defibrillators in Real Cardiac Arrests.

Background: Many patients who suffer an out-of-hospital cardiac arrest will fail to receive bystander intervention (cardiopulmonary resuscitation [CPR] or defibrillation) despite widespread CPR training and the dissemination of automated external defibrillators (AEDs). We sought to investigate what factors encourage lay bystanders to initiate CPR and AED use in a cohort of bystanders previously trained in CPR techniques who were present at an out-of-hospital cardiac arrest.

Methods And Results: One-hundred and twenty-eight semistructured qualitative interviews with CPR-trained lay bystanders to consecutive out-of-hospital cardiac arrest, where an AED was present were conducted (from January 2012 to April 2015, in Denmark).

A qualitative study to identify barriers to deployment and student training in the use of automated external defibrillators in schools.

Background: Student training in use of automated external defibrillators and deployment of such defibrillators in schools is recommended to increase survival after out-of-hospital cardiac arrest. Low implementation rates have been observed, and even at schools with a defibrillator, challenges such as delayed access have been reported. The purpose of this study was to identify barriers to the implementation of defibrillator training of students and deployment of defibrillators in schools.

Effects of a settings-based intervention to promote student wellbeing and reduce smoking in vocational schools: A non-randomized controlled study.

Rationale: School dropout and health risk behavior such as cigarette smoking represent major problems among students attending upper secondary vocational education. Modifications to the social environment may promote educational attainment as well as health and wellbeing of young people. However, there is a need for more evidence-based intervention programs.

What are the barriers to implementation of cardiopulmonary resuscitation training in secondary schools? A qualitative study.

Objective: Cardiopulmonary resuscitation (CPR) training in schools is recommended to increase bystander CPR and thereby survival of out-of-hospital cardiac arrest, but despite mandating legislation, low rates of implementation have been observed in several countries, including Denmark. The purpose of the study was to explore barriers to implementation of CPR training in Danish secondary schools.

Design: A qualitative study based on individual interviews and focus groups with school leadership and teachers.

Shaping the Social: design of a settings-based intervention study to improve well-being and reduce smoking and dropout in Danish vocational schools.

Background: The social environment at schools is an important setting to promote educational attainment, and health and well-being of young people. However, within upper secondary education there is a need for evidence-based school intervention programmes. The Shaping the Social intervention is a comprehensive programme integrating social and educational activities to promote student well-being and reduce smoking and dropout in upper secondary vocational education.

How can we strengthen students' social relations in order to reduce school dropout? An intervention development study within four Danish vocational schools.

Background: This article describes the rationale and contents of an intervention program aimed at strengthening students' social relations in order to reduce dropout from vocational schools in Denmark. Taking its theoretical cue from the concept of 'social participation', a qualitative study was performed to investigate the specific relationships between the social environment within the schools and the institutional structures in order to analyse reasons for school dropout and their relation to well-being, cigarette smoking and substance use.

Methods: The development study was based on ethnographic methods, including 22 qualitative interviews with students 17-19 years old and fieldwork with participant observations at four vocational schools over 40 days, including informal interviews and discussion meetings with managers, teachers, counselors and students.

Temporal trends in coverage of historical cardiac arrests using a volunteer-based network of automated external defibrillators accessible to laypersons and emergency dispatch centers.

Background: Although increased dissemination of automated external defibrillators (AEDs) has been associated with more frequent AED use, the trade-off between the number of deployed AEDs and coverage of cardiac arrests remains unclear. We investigated how volunteer-based AED dissemination affected public cardiac arrest coverage in high- and low-risk areas.

Methods And Results: All public cardiac arrests (1994-2011) and all registered AEDs (2007-2011) in Copenhagen, Denmark, were identified and geocoded.

Coronary heart disease incidence among non-Western immigrants compared to Danish-born people: effect of country of birth, migrant status, and income.

Background: Increasing global migration has made immigrants' health an important topic worldwide. We examined the effect of country of birth, migrant status (refugee/family-reunified) and income on coronary heart disease (CHD) incidence.

Design: This was a historical prospective register-based cohort study.

Psychological consequences of lymphoedema associated with breast cancer: a prospective cohort study.

Background: The aim of this prospective cohort study of women attending a rehabilitation course at the Dallund Rehabilitation Centre was to explore the emotional and psychological aspects of living with lymphoedema, expressed as psychological distress, poorer quality of life and poorer self-reported health.

Methods: Between November 2002 and January 2007 within the FOCARE study, self-completed questionnaires were collected 3 weeks before and 6 and 12 months after the rehabilitation course to elicit sociodemographic, physical and lifestyle information and responses to three psychometric tests. The population consisted of 633 women, 125 with and 508 without verified lymphoedema (time since surgery, 1 month-5 years).
