Nurses’ Perception of, and Barriers to, Delivering Cardiopulmonary Rehabilitation for Heart Failure Patients: A National Survey in Saudi Arabia

Abstract

Background: Heart failure (HF) patients require a holistic management approach to improve their clinical outcomes. Cardiopulmonary rehabilitation (CR) is a core component of HF patients’ management and is supervised by a multidisciplinary team including nurses. Nursing attitudes regarding CR delivery for patients with HF and the possible barriers and factors that potentially affect referral have not been explored. Therefore, this study seeks to evaluate nurses’ attitudes towards the delivery of CR programs and the possible barriers and factors that potentially influence the decision for a referral. Methods: An online survey with eight multiple-choice items was disseminated to all nurses between February and July 2022 in Saudi Arabia. The characteristics of the respondents were described using descriptive statistics. Percentages and frequencies were used to report categorical variables. Results: Overall, 1056 nurses completed the online survey, of which 395 (37.40%) were male. Out of 1056 nurses, 414 (39.20%) strongly agreed that CR would improve patients’ physical fitness, and 392 (37.10%) strongly agreed that CR would reduce breathlessness in patients with HF. In total, 381 nurses strongly agreed (36.10%) that CR would improve HF patients’ palpitation and fatigue. Out of 1056 nurses, 396 (37.50%) strongly agreed that CR would improve HF patients’ ability to perform daily activities, and 326 (30.90%) strongly agreed that CPR would reduce the rate of hospital readmission. The at-home program was the preferred mode of delivering CR programs among 607 (57.50%) nurses. Apart from the exercise component, symptom management was perceived by 704 (66.70%) nurses as the fundamental component of CR programs. The most common patient-related factor that strongly affected the decisions regarding referral was “mobility affected by breathlessness” (57%). A lack of CR centers (46%) was the most common barrier. Conclusion: Nurses perceived CR as an effective management strategy for HF patients. Although a home-based program, with symptom management being an essential component, in addition to the exercise component, was perceived as the preferred mode of delivery, CR centers are lacking, which represented a significant barrier to CR referral from the nurses’ perspective.

1. Introduction

Heart failure (HF) is a severe clinical syndrome associated with symptoms and signs that result from the inability of the heart organ to deliver and pump sufficient blood, along with the necessary nutrients, in order to meet the human body’s requirements, leading to reduced organ perfusion and ultimately death unless it is treated appropriately [1]. Globally, HF is a cause of morbidity and mortality [2]. Exercise intolerance and functional impairment are among the common symptoms of patients with HF. These symptoms frequently worsen with exertion, leading to exacerbations and unnecessary emergency visits or hospitalization [1].

HF is incurable, unlike other diseases or bodily ailments, but pharmacologic and non-pharmacologic strategies may reduce the exacerbations and need for hospitalization [1]. Therefore, a holistic management approach, such as cardiopulmonary rehabilitation (CR), should be implemented to mitigate HF symptoms [3]. CR is an effective non-pharmacologic management strategy for individuals with HF. CR for patients with HF is a comprehensive, multidisciplinary program that includes the assessment of outcomes and exercise training, aiming to improve the patients’ functional capacity and quality of life [2]. The CR program should include a medical examination, patient education, nutritional support, mental health and psychosocial support, and a physical activity counselling program [3,4]. CR must be conducted by a multidisciplinary team that includes doctors, physiotherapists, psychologists, dietitians, social workers, and nurses [2,5].

In the past, the physical activity of patients with HF was believed to aggregate the disease. However, several studies have supported the idea that the participation of patients with HF in physical activity and exercise training is safe and well tolerated in stable HF patients [6,7,8,9]. Furthermore, studies have shown that CR can improve the functional ability, exercise duration, quality of life, peak oxygen consumption, and endothelial function, and reduce the need for hospitalization in individuals with HF [3,10,11,12,13,14]. Interestingly, CR services remain underutilized globally, including in Saudi Arabia [2,15,16]. To the best of our knowledge, there is only one CR program in Saudi Arabia specifically for patients with cardiovascular diseases, including HF [16]. Recently, we conducted a study to assess physiotherapists’ attitudes towards the delivery of CR to HF patients and to identify factors and barriers that might influence CR referral decisions from their perspective. Our findings showed that a supervised hospital-based program with stress management as an essential component was the preferred method of delivering CR, but CR centers were lacking [16]. To promote the implementation of the CR program in Saudi Arabia, it is essential to assess nurses’ perception of the delivery of CR programs for patients with HF, given that nurses are part of the CR team [17]. In addition, the barriers and factors that potentially affect decisions to refer HF patients to the CR program from the perspective of nurses should be considered. Therefore, the study aims to assess nurses’ perception of the delivery of the CR program to patients with HF and to identify possible barriers and facilitating factors that might potentially affect the referral decisions, specifically from the perspective of nurses in the Kingdom of Saudi Arabia.

2. Materials and Methods

2.1. Study Design

This cross-sectional study was carried out between 13 February and 22 July 2022. An online survey platform (Survey Monkey) was used to disseminate the survey and collet data.

2.2. Questionnaire Tool

We used a modified version of a questionnaire that was previously designed, created, and validated by Aldhahir et al. [17,18,19,20]. The questionnaire included eight closed-ended multiple-choice questions. Participants were informed of the study’s objective and the identity of the principal investigator before beginning the questionnaire. The survey began with a question asking the participants if they were interested and willing to participate in this study. The survey stated, “By answering yes in completing the survey question, you freely agree to engage in this study and offer your agreement to utilize your anonymous data for research purposes”. Three to five minutes were the expected duration required to complete the questionnaire. The first part collected data about demographic information. The second part asked participants about three domains, which were effectiveness, components, and delivery methods of CR. This section offered a 5-point Likert scale to enable responses to all the statements. The responses ranged from 1, “strongly disagree”, to 5, “strongly agree”. The last part asked participants about both patient and process-related factors that influence the referral decision regarding CR. Participants were asked to grade the factors. The options, in this part, were no influence, some influence, and a strong influence.

2.3. Study Population and Sampling Strategy

A convenience sampling strategy was used to recruit participants for this study. The target population were nurses who worked with HF cases in Saudi Arabia. To reach more professionals working in Saudi Arabia, the questionnaire was distributed through the nursing committee and social media platforms (Twitter, WhatsApp, Telegram). The criteria for inclusion in the study were clearly specified in the study invitation.

2.4. Sample Size

The design of the study was exploratory; therefore, a sample size calculation was not required.

2.5. Ethical Approval

Jazan University’s Institutional Review Board approved the study (reference number REC-43/03/041).

2.6. Statistical Analysis

The Statistical Package for Social Sciences (SPSS software, Version 25, IBM, Armonk, NY, USA) was used to analyze the data. The reported and displayed categorical variables used percentages and frequencies.

3. Results

Overall, 1056 nurses, including both male 395 (37.40%) and female 661 (62.20%) nurses, responded to the online survey between 13 February and 22 July 2022. The majority of respondents were from the central region (280, 26.51%) and the western region (320, 30.30%) (

). A high percentage of nurses had one to two (26.20%) or three to four (24.20%) years of clinical experience in caring for patients with HF (Table 1). The most common responsibilities of the nurses in caring HF patients were urgent assessment (61.40%), followed by primary care (59.60%) and in-patient treatment (49.70%) (Table 1).

3.1. Opinion on Referring Patients with Heart Failure to Cardiopulmonary Rehabilitation

Out of 1056 nurses, 414 (39.20%) strongly agreed and 438 (41.50%) agreed that CR would improve patients’ physical fitness. Additionally, 392 (37.10%) strongly agreed and 427 (40.40%) agreed that CR would reduce breathlessness in patients with HF. The majority of nurses strongly agreed (381, 36.10%) or agreed (400, 37.90%) that CR would improve HF patients’ palpitation and fatigue. Out of 1056 nurses, 396 (37.50%) strongly agreed and 427 (40.40%) agreed that CR would improve HF patients’ ability to perform daily activities, and 326 (30.90%) strongly agreed and 368 (34.80%) agreed that CR would reduce hospital readmission (

).

3.2. Mode of Delivery and Component of Cardiopulmonary Rehabilitation

Out of 1056 nurses, 607 (57.50%) believed that the preferred way to deliver a CR program is at home, followed by 571 (54.10%) who believed in hospital-supervised programs. (

) In contrast, an online program with healthcare provider support was the least preferred way to deliver a CR program among 525 nurses (49.10%).

Symptom management, followed by stress and weight management, were the essential components of a CR program from the nurses’ perspective, excluding the exercise component, according to 704 (66.70%), 698 (66.10%), and 691 (65.40%) nurses, respectively (Table 3).

3.3. Factors Influencing Referral Decisions for Cardiopulmonary Rehabilitation (Patient-Related)

Nurses perceived mobility affected by breathlessness (57%), followed by patient education and disease management (56.80%) and fatigue related to disease (55.70%), as the most common influencing factors that strongly affect the decision to refer patients with HF for CR (Figure 1).

3.4. Cardiopulmonary Rehabilitation Referral Barriers

From the nurses’ perspective, the main barriers that strongly affect the referral process of patients with HF for CR included the availability of CR centers (46%), followed by the lack of experienced staff who can manage patients with HF (43.50%) and the patients’ doubts about whether or not CR is worthwhile (43%) (Figure 2).

4. Discussion

To the best of our knowledge, this is the first study in Saudi Arabia that assesses attitudes toward and perceptions of the delivery of CR to HF patients and seeks to identify factors and barriers that might affect referral decisions from the nurses’ perspective. Our findings show that nurses perceived CR as an effective management strategy for patients with HF. While a home CR program was seen as the preferred mode of delivery, the lack of CR centers and well-trained staff posed significant barriers to CR referrals. Nurses perceived symptom management, followed by stress and weight management, as the most essential components of a CR program following the exercise component.

CR has been proven to be an effective and safe non-pharmacological management strategy for mitigating HF disease-related symptoms, such as fatigue and shortness of breath, in HF patients [21,22]. It also enhances patients’ exercise capacity, cardiopulmonary fitness, and quality of life by reducing HF-related hospitalization [23,24]. In our study, nurses perceived CR as an effective management strategy for improving patients’ physical activity and disease-related symptoms and reducing the hospital readmission of patients with HF.

The recent COVID-19 pandemic, with its subsequent lockdowns, curfews, and social restrictions, temporarily disrupted face-to-face CR programs. This situation may have affected the current issues with referrals or effective implementation of the programs. In the context of Saudi Arabia, a home-based program has become the most suitable option for CR, given the lack of centers available, accessibility, current infrastructure, and workforce of CR programs or centers. Home-based CR is shown to be as efficient and beneficial as the standard CR program in improving symptoms, especially the exercise capacity and dyspnea [25,26]. Simultaneously, healthcare facilities may use the current resources, even if they are limited, to establish standardized home-based CR programs.

Our study reported that the most common barrier affecting the referral of HF patients for CR from the perspectives of nurses was the lack of CR centers. There is only one CR center in the Kingdom of Saudi Arabia specifically for patients with cardiovascular diseases, including HF [16,27]. This scenario shows and highlights the urgent need or requirement to create and develop new CR programs that meet global standards and can help existing HF patients across the country. The significant gap in the application or practice of such programs requires crucial consideration and action. Given the current scenario, CR can be delivered within the current existing hospital infrastructure [28]. Ward et al. reported that an outpatient rehabilitation program offered at a small hospital was as effective as that provided by a large hospital [29]. Other CR program models which can be delivered include community-based or in-patient-based models [29,30].

Our study reported that the lack of staff or workforce with sufficient training or experience with HF patients was the second most common barrier to referral from the perspectives of nurses. Saudi Arabia is affected by healthcare staff shortages, which may limit the care of HF patients and the establishment of further rehabilitation programs [31]. Previous evidence shows that there is a lack of healthcare providers, and the number of specialized nurses is even lower in Saudi Arabia [31,32]. Additionally, only a small number of locations, programs, and disciplines are capable of managing patients with HF. However, studies have shown that using a multidisciplinary or integrative approach to patients’ management is superior [31,33]. Reduced or lack of awareness concerning HF patient management, including the lack of knowledge about the effectiveness of the interdisciplinary strategies, may explain the shortage of specialized healthcare professionals tackling HF and CR [34]. To develop and bridge the gap, government authorities in Saudi Arabia should implement incentives to the current healthcare workforce to develop skills or undertake training regarding HF, cardiovascular health, and CR. Another option is to offer high-quality education by creating programs that support international studies for the sake of encouraging specialization in cardiorespiratory management and medicines.

In our study, nurses perceived symptoms, stress, and weight management as essential components that need to be implemented within the CR programs, in addition to physical training. This is consistent with the current American College of Cardiology (ACC), American Heart Association (AHA), Heart Failure Society of America (HFSA), and British Association for Cardiovascular Prevention and Rehabilitation (BACPR) clinical guidelines regarding the main components of CR [35,36]. Patients living with HF have limited knowledge about how to manage their symptoms and the stress caused by worsening symptoms, which could be a leading factor in hospital readmission and decreased quality of life [37,38,39,40]. Therefore, promoting patient education is essential, as it may help in the management of HF-related symptoms and to improve overall health and well-being.

Limitations

Some limitations of this study should be highlighted. The study was based on a convenience sampling strategy, which might have caused a potential selection bias. Secondly, the study did not include other healthcare professionals who may be involved in the care of patients with HF. Moreover, it would have benefited from the use of qualitative interviews to gather greater in-depth information regarding the barriers to CR programs.

5. Conclusions

Nurses showed their agreement on the effectiveness of CR in improving clinical outcomes. A home-based program, with symptom management being an essential component, was the preferred mode of CR delivery. The lack of CR centers was a significant barrier to the referral of patients with HF.
