Education in health for patients and healthcare providers, including multidisciplinary programs and e-health, is currently a hot topic.

The idea that educational interventions are beneficial for patients with coronary artery disease is supported by a Cochrane systematic review.1 Nevertheless, further research is needed to determine the best and most cost-effective format for delivery of educational programs.

The article by Fernandes et al. in this issue of the Journal2 examines the specific topic of education and psychological intervention for cardiovascular (CV) patients after acute coronary syndrome (ACS) and their perception of disease and treatment, as well as health habits, to improve adherence to lifestyle changes and risk factor control. This subject, which is important due to the pressing need to decrease CV risk after ACS, has been previously studied in the field of cardiac secondary prevention and rehabilitation.3

On the basis of solid evidence, the guidelines recommend comprehensive post-discharge ACS care that covers management of biomedical and lifestyle risk factors, pharmacotherapy, assessment of psychological factors, and assistance in initiating and maintaining behavioural change.4–6 Educational interventions for CAD patients should be considered an essential part of cardiac rehabilitation (CR).3–7

Health education interventions are comprehensive programs that healthcare providers deliver to patients to help improving clinical outcomes by increasing adherence to and maintenance of healthy behaviours.8 These programs need to take patients’ characteristics into account, and health psychologists are essential for this aspect of the intervention.

As pointed out by Fernandes et al.,2 current thinking is that education and promotion of knowledge during the hospitalization period about the disease, risk factors and treatment improve the rehabilitation process following ACS. As well as patients’ view of their own illness affecting physical and psychological aspects of disease, as the authors show,2 other important socioeconomic aspects are also involved, like return to work.9

The in-hospital post-ACS phase is a unique opportunity to identify risk factors, plan lifestyle changes, and to ensure that the patient is referred to the most suitable center for phase II of the CR program.7 Hospitalization itself provides access to individuals not registered with a general or specialist doctor, who otherwise would not undergo any intervention.10 There is evidence that patients may be more motivated to engage with lifestyle and behavioural changes while still in hospital.11 Experiencing a major life event, such as going into hospital, has been identified as a catalyst for initiation of healthy behaviours and thus an ideal opportunity for intervention.12 The effect of an in-hospital intervention may depend on the individual patient's characteristics, including age, literacy, motivation for change, level of depression and anxiety, and family support. However, such an intervention may be less effective in some patients in the very early stages of hospitalization for ACS, due to the shock resulting from the acute stress of admission. Post-traumatic stress disorder, which occurs in 15-25% of myocardial infarction patients, can cause emotional apathy, lack of interest and memory loss, leading to communication difficulties and amnesia.13

The best time to intervene during hospital stay is immediately before discharge. Patients are stabilized and reassured, knowing they will leave the hospital soon. Nurses can play an important role in this process, communicating the essential information provided by doctors. Psychologists can begin a brief intervention on disease perception and tailored behavioural modification, as demonstrated in Fernandes et al.’s paper,2 which can be continued and extended in outpatient CR.3–6

Patients’ health knowledge needs to be put into practice in daily life. It is unclear which is the best approach to lifestyle and behaviour change at an individual level. Interventions designed to change behaviour may fail to achieve the desired results,14,15 and there is little evidence on the impact of health promotion interventions among specific patient groups.16 Many current interventions target only one risk behaviour, failing to meet the needs of patients with multiple vulnerabilities, such as low levels of health literacy, reduced psychological capability and entrenched cultural and social barriers to health.10 Individualized counseling is the basis for motivation and commitment. Recommendations include assisting individuals to understand the relationship between their behaviour and their health, and helping them to assess the barriers to behaviour change. Decision-making should be shared between caregiver and patient.4,17,18

Previous to the article by Fernandes et al.,2 an interesting in-hospital psychological intervention study10 set out to address barriers to lifestyle behaviour change, assess the feasibility and acceptability to patients of delivering an intervention in an acute setting, and analyze preliminary changes to lifestyle behaviours and measures of self-reported health, well-being, and perceived control after four weeks. It highlighted the need to personalize interventions to the individual's needs and circumstances, help people to develop skills to regulate their behaviour, and provide social support for behaviour change plans. The investigators, who used the framework of the ‘Behaviour Change Wheel’19 for the intervention, showed that it was feasible to design and deliver an evidence-informed psychological intervention in a hospital setting.20 Preliminary health gains were shown by self-reported achievement of goals. Addressing lifestyle risk behaviours such as smoking and poor diet is the single most important way to improve health and reduce premature deaths.21 The intervention reached deprived groups who had multiple factors impeding lifestyle behaviour change22 and enabled the development of resilience and coping skills in these deprived groups that would be transferable to other life situations, including management of long-term conditions.20

An important limitation of in-hospital psychological intervention is that although hospitals are in theory a good place to deliver health promotion interventions, these tend not to be prioritized due to competing staff priorities and lack of time and training.23 For this reason, in-hospital interventions need to be short, direct and concise. There are few examples of similar psychological interventions aimed at addressing multiple lifestyle risk behaviours in hospital patient-based interventions.

Several comments can be made regarding the present study.2 One concerns the randomization process: although the differences were not significant, the intervention group included younger and more educated patients. Both intervention and control groups were around 30% female, as usually occurs in trials. Instead of weekly randomization, it would have been more appropriate to perform a stratified randomization, including age, gender and educational level as parameters for stratification, to avoid bias.

The model of intervention used was generic and not specific for gender or age. As admitted by the authors, the fact that men and women present different psychosocial profiles regarding response and adaptation to ACS requires different interventions, as reported in the literature,24 and underlines the importance of gender-specific intervention protocols in CR. Several programs have been proposed that are adapted to age and gender, in order to optimize the results, including adherence. The impact of these two variables and educational level should be further investigated in future studies and taken into account when planning intervention programs.

Certain aspects of the study need to be clarified. Were all patients asymptomatic and stable at the time of intervention within 2-3 days of ACS? How many were in fact anxious or depressed? The guidelines on CV prevention state that treatment of psychosocial risk factors can counteract psychosocial stress, depression and anxiety, thus facilitating behaviour change and improving quality of life and prognosis. Assessment of such risk factors is essential before any psychological or educational intervention. In a previous paper25 from the same research group as the present paper, anxiety and depression after ACS were significantly reduced and illness cognition improved significantly after a brief psychological intervention, and these changes were maintained or enhanced at one- and two-month follow-up.

Finally, although it is well known that education to improve knowledge of disease, health promotion, risk factor control and lifestyle changes is essential for CV patients, some issues deserve special consideration.

What are the real importance and clinical implications of Fernandes et al.’s study?

(1) The paper calls attention to the need to conduct a larger trial examining in-hospital education, in which patients should be randomized by gender, age and educational level, in order to test different forms of communicating information and effective ways of educating patients to obtain the best outcomes. There is a gap in the evidence, and we still need to determine which interventions are most effective in specific groups, such as young/old, male/female, high/low socioeconomic status, and high/low educational level. Interactions between caregiver and patient should always follow the principles of patient-centered communication.17,26,27

(2) There is evidence that more extensive and/or longer interventions lead to better long-term results in terms of behavioural change and prognosis,17 so education should continue through phase II (outpatient) CR, which we know is frequently not attended. Results from EUROASPIRE IV28 and V29 show that patients hospitalized for CAD only attend CR programs in one half and one third of cases, respectively. An in-hospital intervention enables patients who will not attend a phase II CR program to receive an educational intervention which may increase phase II CR referral and uptake.5 Lifestyle changes may begin earlier.

(3) Considering the importance of phase I CR and an initial psychological intervention, psychologists and nurses need to be specifically involved in this task, which should be included within the scope of the multidisciplinary CR team. At the least, a brief psychological intervention, which had a beneficial effect in this study, can be administered, and at the same time psychologists should identify depression, anxiety and other psychological problems associated with CAD and refer these patients for psychiatric intervention.

(4) To widen the scope of this psychological and educational intervention, e-health education can be developed, which is likely to reach more patients, particularly younger and better-educated groups. Tele-education could continue the initial brief in-hospital intervention, enhancing its results and prolonging their effects over time.

To conclude, I would say that a brief in-hospital psychological intervention in the context of CR following ACS must be better than no intervention at all.
