Background
Every year, approximately 275 000 persons in Europe suffer from an out-of-hospital cardiac arrest (OHCA) [
1] whereas the number of in-hospital cardiac arrest (IHCA) is not known. Recent decades have shown major improvements in survival rates and in Sweden more than 1 000 persons survive cardiac arrest (CA) annually [
2]. Most CAs are caused by a cardiovascular disease [
2] and survivors are at risk of suffering cardiac complications [
3]. Survival may also be associated with neurological impairments due to the lack of oxygen to the brain at the time of the arrest. Severe brain injuries in survivors are uncommon but mild to moderate cognitive impairments, e.g., memory problems have been reported in as many as 30–50 % of the survivors [
4,
5]. Additionally, psychological impairments may be present [
6]. Surviving a life-threatening event such as CA will affect the lives of both survivors and their family members [
7,
8]. Following a near death experience, survivors may become more aware of their vulnerability. Family members can be forced to confront feelings of unreality, uncertainty, hopelessness and, in addition, they can experience feelings of inadequacy and an overwhelming responsibility in the situation [
7]. Moreover, patients and family members are at risk of psychological stress due to the critical illness
per se. It is well-known that patients recovering from critical illness and intensive care are at risk for psychological problems such as anxiety, depression and post-traumatic stress disorders [
9], which may affect the patient’s ability to perform activities in everyday life and participate in society.
Psychological problems, cognitive dysfunction and difficulties in performing activities of daily life have been associated with decreased health among CA survivors [
10]. A review article concludes that health and quality of life (QoL) among survivors appears to be acceptable or good, but also reports major variations between different studies and within study populations [
11]. Some studies report that suffering a CA has negative effects on QoL, and that survivors have poorer QoL compared to a normal population [
10,
12,
13]. Other studies have not been able to show any differences [
14‐
16].
In order to address problems caused by CA and to support health among survivors and their family members, structured post CA care is needed. Today, national guidelines for post CA care and follow-up programs are not available in Sweden. The Swedish Resuscitation Council (SRC) has recommended an information package for survivors and their family members since 2011 [
17]. This material contains information about CA in general and stories of experiencing CA, told by survivors and their family members, in particular. However, the success of the implementation is unknown. Patients suffering CA are often admitted to intensive care units (ICU) [
2]. In Sweden, patients with critical illness in general participate in follow-ups performed by intensive care nurses post ICU discharge. However, these follow-ups have been described as varying extensively in design and not being available for all [
18]. The goal of the ICU follow-up is to promote the patients’ recovery by focusing on three domains: the past, the present and the future. The past aims to support patients’ understanding, the present includes actual physical, cognitive and psychological status, and the future includes rehabilitation or other interventions to promote health. The last step has been the weakest point so far in Scandinavia [
18], where other countries promote more structured guidelines for rehabilitation, as in the UK with the National Institute for Health and Clinical Excellence (NICE) guidelines [
19]. Whether these ICU follow-ups include the majority of CA survivors is unknown.
Since cardiac etiology is common [
2], CA survivors are likely to receive cardiovascular follow-up, primarily focused on physiological secondary prevention [
20]. However, because they are at risk of also suffering neurological and emotional complications [
5,
6], which might affect their QoL [
10], specific care and follow-up is necessary [
6,
21‐
23]. Previous research describing specific post CA care and follow-up is sparse [
24‐
27]. In many countries, including Sweden, national guidelines for post CA care and follow-up programs are not available, and current practice has, to our knowledge, not previously been investigated. The aim of this survey was therefore to describe current post CA care and follow-up in Sweden.
Discussion
Despite the need for structured post CA care for survivors and family members, few studies have described these aspects [
24‐
27]. Overall, this survey showed that guidelines are not available at many hospitals in Sweden, and consist mainly of traditional cardiac rehabilitation with follow-up visits at cardiac reception units. Resuscitation coordinators in general lack knowledge about how post CA care is organized. Answers to the open-ended question confirm these findings. This raises the question of whether the hospitals meet post CA care needs, among survivors and family members, in order for health to be restored and improved over time.
Since cardiac follow-up does not include all CA patients and ICU follow-ups seem to be uncommon, there is no clear pathway for CA survivors and their family members. According to answers from the open-ended question, differences could depend on diagnosis, cause of CA and type of hospital ward. In addition, our results imply great variability in care between hospitals. In contrast to national intentions, striving for equal care [
34], our findings showed that quality of post CA care and follow-up seems to depend on where the patient lives. This is not unique to Sweden and corresponds to the results of a Canadian study by Keenan, et al. [
35]. In their study, regional differences in ICU care after CA were also described. However, the results entail the importance of local, national and international guidelines. Encouragingly, written information material with the aim to support patients’ and family members’ recovery seemed to be implemented as an element of post CA care at the majority of the Swedish hospitals, and therefore in some ways can help to create uniformity. Further, processes that promote families’ ability to cope with the life-threatening event might be strengthened by learning from the experiences of others [
28].
As in previous investigations of post ICU care and follow-up [
18], the content of the visits in our survey mainly included the present status of the patients (e.g. assessing current physical function, daily activities and health). The lack of routines on how to handle problems identified, shows low focus on rehabilitation in order to support and promote health and recovery over time. A randomized controlled follow-up intervention especially designed for CA survivors has been tested in the Netherlands [
36]. This [
37] is one of few health-promoting interventions intended for CA survivors and their caregivers, which have been described in detail. This individualized, semi-structured psychosocial intervention, ‘
Stand still…, and move on’, is designed for early detection of emotional and cognitive problems, and for providing information and support. It also aims to promote self-management as well as an early referral to specialized care if needed. The intervention consists of one to six consultations conducted by specially trained nurses [
36]. The recently published results showed that the intervention improved QoL and decreased anxiety among CA survivors at one-year post CA. However, it did not improve outcome for caregivers. These results are very likely to contribute to improvements in post CA care and follow-up [
25].
Less than half of the hospitals reported that they had as a routine to invite family members to participate in post CA care. However, it remains unclear how and if concerns among family members are detected. Maybe they are invited to participate in follow-up, or maybe they are forgotten. Since mild cognitive dysfunction appears to be common among OHCA survivors [
4,
5], and cognitive dysfunction among survivors has been shown to be associated with strain among family members [
38], it is important for family members to be included in post CA care. In addition, stress, anxiety and decreased QoL among relatives have been reported [
23]. As previous dyad studies show that patients and spouses affect each other’s health [
39,
40], survivors and their family members will likely affect each other in the same way. There is also reason to assume that the function of the family is affected by, as well as affects, health and QoL among both patients and family members [
41]. Family members might play an important part in the post CA care. Therefore, nursing should actively promote strengths and health among both survivors and their family members [
28].
A minority of the hospitals used PROMs to detect problems among survivors. After this study was conducted, the Swedish registry for cardiopulmonary resuscitation began including PROMs in the follow-up, for example, health-related quality of life among survivors using questionnaires and telephone interviews. PROM data will contribute to better knowledge of the life situation among survivors, since the number of patients available for research will increase. This knowledge could constitute a starting point for the testing of screening methods and health promoting interventions as well as the creating of national guidelines. In addition, PROMs play a key role for person centred care, by influencing the care based on patient specific information [
42]. In a recently published editorial, Smith and Bernard [
16] highlight the need for more research to determine what outcome measures accurately describe obstacles important to patient- and family health after a CA event. They argue that good measurements, with the ability to capture predictors for poor health, could aim to target and evaluate interventions. Consensus has not been reached concerning what assessments to use to evaluate outcome after a CA. However, one of the most descriptive guidelines can be found in the recommendations of the American Heart Association from 2011 [
43]. In a recently published study of 249 OHCA survivors [
38] it was concluded that questionnaires and telephone interviews to assess cognitive function and QoL can be recommended for CA research.
In the present study, most of the follow-up visits took place within the first three months after the CA. However, a few open-ended responses indicated that follow up visits were sometimes based on patients’ needs. This might indicate a growing awareness of health as multidimensional [
28], making the patient perspective essential. Further, there is a lack of knowledge and guidance about optimal timing and intervals for evaluating the patient’s QoL after a CA. The UK NICE guidelines for follow-up after a general critical illness suggest a structured pathway for assessments: at ICU stay (during the stay and before discharge), at ward-based care (during and before discharge), and at a follow-up visit 2–3 months after discharge [
19]. A structured pathway for rehabilitation of present findings has further been suggested by Jones [
9]. However, these guidelines are not designed especially for a CA group and most of the interventions still lack sufficient evidence. In addition, many survivors, especially those suffering IHCA, may not be admitted to an ICU at all.
Nurses, in particular those working at cardiac- and intensive care reception units, should be aware that CA patients and relatives could be at risk of not receiving optimal post CA care. Therefore, they should pay special attention to individual needs and possible health-problems. In order to improve post CA care and follow-up, future research should focus on the needs of CA survivors and their family members and on the testing of health promoting interventions. Such knowledge will be helpful for improving hospital care and developing guidelines.
Limitations
Cross-sectional surveys with descriptive designs are beneficial approaches for health care researchers, particularly in new area of inquiry. However, they have some drawbacks that need to be considered [
44]. The questionnaire was developed specifically for this study and had not undergone any extensive validation. However, the tool development was guided by a well-used conceptual framework about health care quality [
31,
45]. Although the questions cover all three components, i.e. structure, process and outcome, not all aspects of these were included. This choice was made to make the questionnaire short and easy to complete. The open-ended question allowed respondents to provide supplementary answers to the closed-ended questions, as well as to express other aspects of post CA care. In addition, content validity was determined by a researcher with extensive experience in instrument development and psychometrics. The response rate was high, which indicated that the questions were easy to understand and complete. This also indicated an interest for the study. In addition to a high response rate, the respondents were well spread geographically and there were different types of cities, and small and large hospitals. Despite the high response rate, the findings should be interpreted and generalized with some caution.
Another limitation was sparse qualitative data from the open-ended question, reported by 15 of the respondents. For this reason, qualitative data were deductively grouped according to the six established topics, followed by inductive categorization and abstraction of the data. With more extensive material, it would have been preferable to start the analysis by coding the data. Despite this limitation, the qualitative data contributed to a better understanding of the quantitative findings.
In this study, we sent the questionnaire to resuscitation coordinators, since they were most likely to know the routines at the hospitals. However, in order to get more comprehensive results, answers from other groups, e.g., cardiac rehabilitation nurses or nurses responsible for post ICU care and follow-up, might also have been of interest. Another weakness is that we cannot say anything about which hospitals completed the questionnaire and which did not, since the answers were given anonymously. Still our results imply the need for improvements in post CA care, e.g., by finding structured pathways for referral and including other specialities, in order to increase the chances of promoting all aspects of health and QoL among survivors and their families, especially emotional and cognitive aspects.
