More people are surviving a cardiac arrest due to improvements in bystander resuscitation and acute hospital care. However, many survivors of cardiac arrest are left with physical, mental and social problems impacting negatively on their quality of life. At present there are no specialist interventions for survivors of cardiac arrest in Denmark and very few have been evaluated internationally. Rehabilitation for people after cardiac events or brain injury have shown significant physical and mental well-being benefits, indicating the same may be true for survivors of cardiac arrest. This pilot study will test the feasibility and acceptability of a residential rehabilitation intervention focused on fatigue, and the physical, mental and social consequences of cardiac arrest. In addition, the pilot study will discover if the intervention has any effect on self-report measures, including fatigue, mental well-being and activity of the survivors of cardiac arrest who participate, and on the mental well-being of relatives of these survivors.
The number of people surviving a cardiac arrest is increasing every year due to advances in pre-hospital and acute medical care. In Denmark, one year survival after out-of-hospital cardiac arrest improved from 4-13% between 2001 and 2014; this amounts to at least 500 new survivors every year. But after the acute phase ends, many survivors of cardiac arrest (SCA) suffer an uncertain future. Most SCA will have a new or ongoing cardiac condition. They may suffer from mental trauma due to surviving a near death experience. Further, reduced oxygen levels to the brain during a cardiac arrest, can cause brain injury in up to 50% of SCA. This combination of cardiac, traumatic and neurological factors causes survivors to suffer from a wide range of physical, psychological and cognitive problems impacting negatively on their quality of life. Relatives of SCA have also been found to suffer from emotional problems due to becoming a carer for their loved one. Normally in Denmark, a patient population with such a heavy burden, like SCA and their relatives would receive help to restore them to daily life but at present there are no specialist rehabilitation interventions provided for SCA in Denmark. Research involving rehabilitation interventions for people after brain injury or cardiac events has shown significant physical, psychological and quality of life benefits, indicating the same may be true for SCA. The European Resuscitation Council and other international experts recommend all SCA receive rehabilitation tailored to their needs but very few research studies exist on which to base the design of these rehabilitation interventions. The Medical Research Council (MRC) in the United Kingdom state that in clinical research there is too strong a focus on the main evaluation of an intervention. This means inadequate development and piloting work, leading to weaker interventions that are less likely to be implemented. Before performing large-scale testing of an intervention, the MRC advocates a systematic development phase that tests the feasibility of the new intervention. Though examination of current literature and workshops with researchers, clinicians, survivors of cardiac arrest and their relatives a new comprehensive rehabilitation intervention has been developed. The objectives of this study are to, firstly, test the feasibility and acceptability of the intervention. Secondly, to determine the effect of the intervention on patient reported outcomes covering fatigue, physical activity, psychological well-being and quality of life. In addition, the effect of the intervention on the mental well-being of any relatives who take part in the intervention. Recruitment will take place via publicity through REHPA, the five cardiac centers in Denmark and via the Danish Heart Foundation. Potential participants will apply via an application form and be screened by the research team for eligibility.

The intervention will be delivered by a multidisciplinary team. There will be individual testing and feedback on physical capacity and cognitive ability. Group sessions will include education on the consequences of cardiac arrest, promotion of techniques to ameliorate these consequences, for example, increasing physical activity or energy conservation. Additional sessions will cover psychological reactions; family life; work life; intimacy; and existential considerations. Participants will have a course information book with a physical activity training diary and problem-solving therapy worksheets to use at home for 12-weeks. They will receive one phone call from the clinical team during this period. The 2-day return stay will revisit the subjects from the first 5-day stay. Participating survivors who have a relative that wishes to attend will be included in all the group sessions and individual feedback but will not take part in the physical capacity or cognitive ability tests.

Recruitment rate for participants
Recruitment rate for participants (survivors and relatives), number of participants recruited per week.
Time frame: Time frame: From month 4 to month 1 before intervention start date
Participant satisfaction assessed by a likert scale
Participant (survivors and relatives) satisfaction with intervention as assessed by a 5-point likert scale for each component of the intervention. In addition, qualitative interviews with participants (survivors and relatives)
Time frame: At eleven weeks months
Completion of study outcome measures
Percentage of participants (survivors and relatives) who complete each outcome measure
Time frame: Baseline, eleven weeks and 6 months
Adherence to intervention by participants
Percentage of participants (survivors and relatives) who achieve minimum adherence levels, that is attendance at both the 5-day rehabilitation stay and 2-day follow-up rehabilitation stay.
Time frame: At eleven weeks
Efficacy of improving fatigue as measured by the change from baseline in the Modified Fatigue Impact Scale
The Modified Fatigue Impact Scale assesses how fatigue impacts functional activities, the self-report questionnaire has 21 items in three sub-scales (physical, cognitive and psychosocial). Scores are summed to give a total. Total scores range from 0-84. The ranges of scores for each sub-scale are as follows: physical, 0 to 36; cognitive, 0 to 40; and psychosocial, 0 to 8. Higher scores indicate a greater impact of fatigue.
Time frame: Baseline, at eleven weeks, 6 months
Efficacy of improving fatigue as measured by the change from baseline in the Multidimensional Fatigue Inventory
The Multidimensional Fatigue Inventory measures fatigue severity, it covers five dimensions; general fatigue, physical fatigue, reduced activity, reduced motivation and mental fatigue. Higher scores indicate a higher level of fatigue, with 4 being no fatigue and 20 the worst imaginable fatigue
Time frame: Baseline, at eleven weeks, 6 months
Efficacy of improving physical activity as measured by the change from baseline in the International Physical Activity Questionnaire Short
The International Physical Activity Questionnaire Short is a self-report questionnaire that has 7 items providing information on time spent walking, in vigorous- and moderate- intensity activity. Total time spent performing activities is summed and results reported in categories low, medium and high physical activity levels.
Time frame: Baseline, at eleven weeks, 6 months
Efficacy of improving activity and participant as measured by the change from baseline in the World Health Organisation Disability Assessment Schedule 2.0
The World Health Organisation Disability Assessment Schedule 2.0 is a self-report questionnaire that assesses disability and functioning in the prior month. It assesses six different adult life tasks: 1) Understanding and communication; 2) Self-care; 3) Mobility (getting around); 4) Interpersonal relationships (getting along with others); 5) Work and household roles (life activities); and 6) Community and civic roles (participation). There are 36 items scored from 0- no difficulty to 4- extreme difficulty or cannot do. Total scores range from 0 to 144 with a higher score indicating greater difficulty with activity and participation. Completed by survivors only.
Time frame: Baseline, at eleven weeks, 6 months
