Adherence to lifestyle changes after coronary artery bypass graft: Outcome of preoperative peer education

Effectiveness of Peer-Based and Conventional Video Education in Reducing Perioperative Depression and Anxiety Among Coronary Artery Bypass Grafting Patients: A Randomized Controlled Trial

PURPOSE

Depression and anxiety are common comorbidities in patients undergoing coronary artery bypass grafting (CABG), with potential adverse effects on surgical outcomes. Effective interventions to reduce depression and anxiety in these patients are therefore warranted. This study investigated the effectiveness of peer-based video education compared to conventional video education in reducing perioperative depression and anxiety in CABG patients.

DESIGN

A three-arm, parallel, randomized, controlled trial design was employed.

METHODS

A total of 114 participants were randomly assigned to 1 of 3 groups (n = 38 per group): standard education (control), conventional video education, and peer-based video education. State anxiety levels were measured using the Spielberger State Anxiety Questionnaire at 1 day before surgery (baseline), 1 hour before surgery, and 4 weeks after surgery. Depression levels were measured using the Beck Depression Inventory Short-Form at baseline and 4 weeks after surgery. Statistical analyses, including χ2, Fisher's exact test, one-way analysis of variance, and repeated-measures analysis of variance, were applied to analyze the collected data.

FINDINGS

Both peer-based and conventional video education groups demonstrated lower preoperative anxiety levels compared to the control group. However, only the peer-based video education group exhibited a statistically significant difference (P < .05). Four weeks after surgery, anxiety and depression levels decreased in all participants compared to baseline, with no statistically significant differences among the three groups.

CONCLUSIONS

Our findings suggest that peer-based video education is more effective in controlling preoperative anxiety in patients undergoing CABG than conventional video education and standard education. Moreover, video-based education, whether conventional or peer-based, appears to be as effective as standard education in reducing anxiety and depression 4 weeks after CABG surgery. Further research is warranted to investigate the influence of content and presentation methods on patient outcomes and explore the potential long-term benefits of video-based education in promoting patient care.

Peer-support interventions and related outcomes in patients with myocardial infarction: A systematic review

Objective

Myocardial infarction (MI) is one of the main causes of disability and death worldwide. Peer-support can ameliorate the psychological and physical morbidities associated with heart diseases. The aim of this study was to determine whether peer-support interventions could improve the psychological and behavioral health outcomes commonly experienced by MI patients.

Methods

In this systematic review, international databases (PubMed, Web of Science, and Scopus) were searched to gather related publications up to March 2023. Eligible papers were those addressing the outcomes of peer-support interventions in individuals with a history of MI.

Result

Twelve clinical trials published in English with a Jadad score of 3 or 4 (out of 5) were included in the final review. These studies used four approaches to deliver peer-support interventions: face-to-face, telephone-based, educational videos, and group discussion. The results showed that peer-support could have a positive effect on depression, anxiety, quality of life, sexual performance, self-care, and medication adherence.

Conclusion

Considering the serious impacts of MI on life, these patients need empowerment training. Peer-support can be used as a complementary supportive method to reduce MI patients' psychological complications and improve their behavioral outcomes.

Social network interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease

BACKGROUND

Globally, cardiovascular diseases (CVD, that is, coronary heart (CHD) and circulatory diseases combined) contribute to 31% of all deaths, more than any other cause. In line with guidance in the UK and globally, cardiac rehabilitation programmes are widely offered to people with heart disease, and include psychosocial, educational, health behaviour change, and risk management components. Social support and social network interventions have potential to improve outcomes of these programmes, but whether and how these interventions work is poorly understood.  OBJECTIVES: To assess the effectiveness of social network and social support interventions to support cardiac rehabilitation and secondary prevention in the management of people with heart disease. The comparator was usual care with no element of social support (i.e. secondary prevention alone or with cardiac rehabilitation).  SEARCH METHODS: We undertook a systematic search of the following databases on 9 August 2022: CENTRAL, MEDLINE, Embase, and the Web of Science. We also searched ClinicalTrials.gov and the WHO ICTRP. We reviewed the reference lists of relevant systematic reviews and included primary studies, and we contacted experts to identify additional studies.  SELECTION CRITERIA: We included randomised controlled trials (RCTs) of social network or social support interventions for people with heart disease. We included studies regardless of their duration of follow-up, and included those reported as full text, published as abstract only, and unpublished data.

DATA COLLECTION AND ANALYSIS

Using Covidence, two review authors independently screened all identified titles. We retrieved full-text study reports and publications marked 'included', and two review authors independently screened these, and conducted data extraction. Two authors independently assessed risk of bias, and assessed the certainty of the evidence using GRADE. Primary outcomes were all-cause mortality, cardiovascular-related mortality, all-cause hospital admission, cardiovascular-related hospital admission, and health-related quality of life (HRQoL) measured at > 12 months follow-up.  MAIN RESULTS: We included 54 RCTs (126 publications) reporting data for a total of 11,445 people with heart disease. The median follow-up was seven months and median sample size was 96 participants. Of included study participants, 6414 (56%) were male, and the mean age ranged from 48.6 to 76.3 years. Studies included heart failure (41%), mixed cardiac disease (31%), post-myocardial infarction (13%), post-revascularisation (7%), CHD (7%), and cardiac X syndrome (1%) patients. The median intervention duration was 12 weeks. We identified notable diversity in social network and social support interventions, across what was delivered, how, and by whom.  We assessed risk of bias (RoB) in primary outcomes at > 12 months follow-up as either 'low' (2/15 studies), 'some concerns' (11/15), or 'high' (2/15). 'Some concerns' or 'high' RoB resulted from insufficient detail on blinding of outcome assessors, data missingness, and absence of pre-agreed statistical analysis plans. In particular, HRQoL outcomes were at high RoB. Using the GRADE method, we assessed the certainty of evidence as low or very low across outcomes. Social network or social support interventions had no clear effect on all-cause mortality (risk ratio (RR) 0.75, 95% confidence interval (CI) 0.49 to 1.13, I2 = 40%) or cardiovascular-related mortality (RR 0.85, 95% CI 0.66 to 1.10, I2 = 0%) at > 12 months follow-up. The evidence suggests that social network or social support interventions for heart disease may result in little to no difference in all-cause hospital admission (RR 1.03, 95% CI 0.86 to 1.22, I2 = 0%), or cardiovascular-related hospital admission (RR 0.92, 95% CI 0.77 to 1.10, I2 = 16%), with a low level of certainty. The evidence was very uncertain regarding the impact of social network interventions on HRQoL at > 12 months follow-up (SF-36 physical component score: mean difference (MD) 31.53, 95% CI -28.65 to 91.71, I2 = 100%, 2 trials/comparisons, 166 participants; mental component score MD 30.62, 95% CI -33.88 to 95.13, I2 = 100%, 2 trials/comparisons, 166 participants).  Regarding secondary outcomes, there may be a decrease in both systolic and diastolic blood pressure with social network or social support interventions. There was no evidence of impact found on psychological well-being, smoking, cholesterol, myocardial infarction, revascularisation, return to work/education, social isolation or connectedness, patient satisfaction, or adverse events.  Results of meta-regression did not suggest that the intervention effect was related to risk of bias, intervention type, duration, setting, and delivery mode, population type, study location, participant age, or percentage of male participants.  AUTHORS' CONCLUSIONS: We found no strong evidence for the effectiveness of such interventions, although modest effects were identified in relation to blood pressure. While the data presented in this review are indicative of potential for positive effects, the review also highlights the lack of sufficient evidence to conclusively support such interventions for people with heart disease. Further high-quality, well-reported RCTs are required to fully explore the potential of social support interventions in this context. Future reporting of social network and social support interventions for people with heart disease needs to be significantly clearer, and more effectively theorised, in order to ascertain causal pathways and effect on outcomes.

Prehabilitation before elective coronary artery bypass grafting surgery: a scoping review

OBJECTIVE

The objective of this scoping review was to identify and map existing preoperative interventions, referred to as prehabilitation, in adult patients at home awaiting elective coronary artery bypass grafting surgery. This review also sought to report feasibility and patient experiences to shape clinical practice and underpin a future systematic review.

INTRODUCTION

As patients age, comorbidities become more common. Strategies to improve postoperative outcomes and to accelerate recovery are required in patients undergoing coronary artery bypass grafting. Prehabilitation refers to a proactive process of increasing functional capacity before surgery to improve the patient's ability to withstand upcoming physiologic stress and, thus, avoid postoperative complications.

INCLUSION CRITERIA

Studies that included adult patients awaiting coronary artery bypass grafting surgery at home and that described interventions optimizing preoperative physical and psychological health in any setting were included.

METHODS

The JBI methodology for conducting scoping reviews was used to identify relevant studies in MEDLINE, CINAHL, Cochrane Library, Embase, Scopus, SweMed+, PsycINFO, and PEDro. Gray literature was identified searching Google Scholar, ProQuest Dissertations and Theses, MedNar, OpenGrey, NICE Evidence search, and SIGN. Studies in Danish, English, German, Norwegian, and Swedish were considered for inclusion, with no geographical or cultural limitations, or date restrictions. Two independent reviewers screened titles and abstracts, and studies meeting the inclusion criteria were imported into Covidence. Sixty-seven studies from November 1987 to September 2022 were included. The data extraction tool used for the included papers was developed in accordance with the review questions and tested for adequacy and comprehensiveness with the first 5 studies by the same 2 independent reviewers. The tool was then edited to best reflect the review questions. Extracted findings are described and supported by figures and tables.

RESULTS

Sixty-seven studies were eligible for inclusion, representing 28,553 participants. Analyses of extracted data identified various preoperative interventions for optimizing postoperative and psychological outcomes for adult patients awaiting elective coronary artery bypass grafting surgery. Based on similarities, interventions were grouped into 5 categories. Eighteen studies reported on multimodal interventions, 17 reported on psychological interventions, 14 on physical training interventions, 13 on education interventions, and 5 on oral health interventions.

CONCLUSION

This scoping review provides a comprehensive summary of strategies that can be applied when developing a prehabilitation program for patients awaiting elective coronary artery bypass surgery. Although prehabilitation has been tested extensively and appears to be feasible, available evidence is mostly based on small studies. For patients undergoing elective coronary artery bypass grafting to derive benefit from prehabilitation, methodologically robust clinical trials and knowledge synthesis are required to identify optimal strategies for patient selection, intervention design, adherence, and intervention duration. Future research should also consider the cost-effectiveness of prehabilitation interventions before surgery. Finally, there is a need for more qualitative studies examining whether individual interventions are meaningful and appropriate to patients, which is an important factor if interventions are to be effective.

Facilitators and barriers to return to work in patients after heart surgery

BACKGROUND

Recognition of the factors influencing returning to work by people after heart surgery is very significant in performing supportive interventions. Factors affecting return to work of Iranian patients after surgery are unknown. Therefore, a qualitative study is in demand in order to close this knowledge gap. This study was aimed to explore the facilitators and barriers of return to work after heart surgery.

MATERIALS AND METHODS

This qualitative study was conducted during 2020-2021. People after heart surgery were studied in this research. Nineteen interviews were performed with 17 participants. The main participants were selected from the cardiac surgery ward of Golestan Province Hospital. The sampling method was purposeful. Data were collected through semi-structured interviews. Questions were asked in an unguided and open-ended manner. Data analysis was performed by qualitative content analysis.

RESULTS

According to the results, "perceived psychosocial support," "individual characteristics," and "occupational factors" were considered as facilitators and "effects of heart surgery" and "limited support of public and private institutions" were introduced as barriers to return to work in patients after heart surgery.

CONCLUSIONS

The effects caused by heart surgery and limited support of public and private institutions were identified as barriers to return to work. Cardiac rehabilitation after surgery can reduce the impact of heart surgery and can help people to return to work. It is recommended that the planners of the Ministry of Labor and Social Welfare and Health, with the support of insurance organizations, help solve the work problems of people after heart surgery.

What is the volume, diversity and nature of recent, robust evidence for the use of peer support in health and social care? An evidence and gap map

Background

Peer support interventions involve people drawing on shared personal experience to help one another improve their physical or mental health, or reduce social isolation. If effective, they may also lessen the demand on health and social care services, reducing costs. However, the design and delivery of peer support varies greatly, from the targeted problem or need, the setting and mode of delivery, to the number and content of sessions. Robust evidence is essential for policymakers commissioning peer support and practitioners delivering services in health care and community settings. This map draws together evidence on different types of peer support to support the design and delivery of interventions.

Objectives

The aim of this map was to provide an overview of the volume, diversity and nature of recent, high quality evidence on the effectiveness and cost-effectiveness of the use of peer support in health and social care.

Search Methods

We searched MEDLINE, seven further bibliographic databases, and Epistemonikos for systematic reviews (in October 2020), randomised controlled trials (in March 2021) and economic evaluations (in May 2021) on the effectiveness of peer support interventions in health and social care. We also conducted searches of Google Scholar, two trial registers, PROSPERO, and completed citation chasing on included studies.

Selection Criteria

Systematic reviews, randomised controlled trials and economic evaluations were included in the map. Included studies focused on adult populations with a defined health or social care need, were conducted in high-income countries, and published since 2015. Any measure of effectiveness was included, as was any form of peer support providing the peer had shared experience with the participant and a formalised role.

Data Collection and Analysis

Data were extracted on the type of peer support intervention and outcomes assessed in included studies. Standardised tools were used to assess study quality for all studies: assessing the methodological quality of systematic reviews 2 for systematic reviews; Cochrane risk of bias tool for randomised controlled trials; and consensus health economic criteria list for economic evaluations.

Main Results

We included 91 studies: 32 systematic reviews; 52 randomised controlled trials; and 7 economic evaluations. Whilst most included systematic reviews and economic evaluations were assessed to be of low or medium quality, the majority of randomised controlled trials were of higher quality. There were concentrations of evidence relating to different types of peer support, including education, psychological support, self-care/self-management and social support. Populations with long-term health conditions were most commonly studied. The majority of studies measured health-related indicators as outcomes; few studies assessed cost-effectiveness. Studies were unevenly distributed geographically, with most being conducted in the USA. Several gaps were evident regarding the delivery of peer support, particularly the integration of peers and professionals in delivering support and interventions of longer duration.

Authors' Conclusions

Although there is evidence available to inform the commissioning and delivery of peer support in health and social care, there are also clear gaps that need to be addressed to further support provision, particularly regarding cost-effectiveness. The effectiveness of peer support in different countries, with varying health and social care systems, is a priority for future research, as is the integration of peers with professionals in delivering peer support.

Learning Needs and Educational Strategies for Adult Patients in the Preoperative Period of Myocardial Revascularization: Scoping Review

Objective: To identify and map learning needs and educational strategies for adult patients in the preoperative period of myocardial revascularization. Materials and method: Scoping review conducted between March and April 2021 in national and international databases to identify records published in scientific journals and gray literature, without period. Results: The selected sample consisted of 35 records, composed mostly of articles (32; 91.42 %) published from 1990 to 2021. The learning needs of patients before surgery were categorized into cardiovascular system and coronary artery disease; procedures and routines before, during, and after surgery. In addition, several educational strategies implemented in the studies were identified. Conclusions: The learning needs identified can contribute to planning and implementing patient-centered educational strategies before surgery.

Determining Factors for Independent Walking in Patients Undergoing Cardiovascular Surgery: Differences between Coronary Artery Bypass Grafting, Heart Valve Surgery, and Aortic Surgery

Physical deconditioning often occurs during the acute phase after cardiovascular surgery, and unassisted walking is required to achieve independence, to manage cardiac diseases, and to prevent recurrences. This study aims to investigate the characteristics of independent walking after cardiovascular surgery. We conducted a retrospective cohort study in patients who underwent cardiovascular surgeries (total of 567 patients): 153 in the coronary artery bypass grafting (CABG) group, 312 in the heart valve surgery group, and 102 in the aortic surgery group. We evaluated the effect of each surgery group on the cardiac rehabilitation (CR) progression. The factors associated with independent walking were age, renal diseases, intensive care unit (ICU) length of stay, and post-operative respiratory complications in the CABG group. In the heart valve surgery group, the factors were New York Heart Association functional classification, renal and respiratory diseases, ICU length of stay, duration of mechanical ventilatory support, and post-operative cardiovascular and respiratory complications. In the aortic surgery group, these were ICU length of stay and acute kidney injury. The CR progression in patients who underwent aortic surgery was significantly longer than those who underwent CABG and heart valve surgery (p < 0.001). New intervention strategies are needed for patients with prolonged ICU stays.

Multimedia in preoperative patient education for adults undergoing cancer surgery: A systematic review

PURPOSE

The purpose of this systematic review was to determine whether adequate research evidence exists to support utilizing multimedia technology in the preoperative education of adult cancer patients.

METHODS

A systematic search of Medline, CINAHL, Web of Science, and PsycINFO databases from 2010 through September 24, 2020, was performed. The review included quantitative studies that examined whether education delivered by multimedia impacted levels of anxiety, knowledge acquisition, satisfaction, and compliance. The research quality was evaluated using the Joanna Briggs Institute Critical Appraisal Tool specific to the study design.

RESULTS

The database search identified 529 scientific articles, of these nine studies met the eligibility criteria (n = 5 randomized controlled trials; n = 4 quasi-experimental studies). The education interventions included a variety of researcher-developed, multimedia modalities, consisting of video (n = 7), a computer program (n = 1), and a tablet application (n = 1). The methodological rigor varied among these studies. Multimedia patient education resulted in decreased anxiety and improved knowledge acquisition within groups; however, there was no significant difference when compared to traditional methods. Patients were also similarly satisfied and compliant with both education methods.

CONCLUSIONS

In all studies, the healthcare provider played a prominent role in both multimedia and traditional interventions, revealing the strong influence of the interpersonal connection in the delivery of preoperative education. Future research is needed to investigate whether more interactive technology could improve patient outcomes.

Improving health-related quality of life and adherence to health-promoting behaviors among coronary artery bypass graft patients: a non-randomized controlled trial study

PURPOSE

This study aimed to determine the impact of a healthy lifestyle empowerment program on health-related quality of life and adherence to health-promoting behaviors in coronary artery bypass graft patients.

METHODS

This non-randomized controlled trial was conducted in 2019 on 97 coronary artery bypass graft patients in Iran. Participants were selected by culturally pragmatic and non-randomized method and assigned to healthy lifestyle empowerment program group (HLEPG) (n = 49) and conventional education group (CEG) (n = 48). Data were collected by the 12-item short-form health survey (SF-12) and health-promoting lifestyle profile II (HPLP2), which were administered at baseline and three-month follow-up. The healthy lifestyle empowerment program and conventional education as two interventions were performed for HLEPG and CEG, respectively. Data analysis was performed using the paired t-test, independent t-test, analysis of covariance and linear mixed method at the 0.05 significance level.

RESULTS

In the follow-up, both groups showed a significant increase in the mean score of health-related quality of life (p ≤ 0.001) but this increase was visibly greater in the HLEPG (from 23.47 ± 7.48 to 35.60 ± 5.95) than in the CEG (from 22.93 ± 5.93 to 27.6 ± 4.90). The healthy lifestyle empowerment program also significantly increased the mean score of adherence to health-promoting behaviors in the HLEPG (p ≤ 0.001), whereas no such change was observed in the CEG. The results of the linear mixed model showed that the follow-up scores health-related quality of life and adherence to health-promoting behaviors of the HLEPG were 27.26 and 7.56 units significantly greater than the CEG after HLEP, respectively (p < 0.001).

CONCLUSION

Considering the results of this study, health care providers are recommended to devise and implement healthy lifestyle empowerment programs to improve the health-related quality of life of coronary artery bypass surgery patients.
