Enhancing participation in cardiac rehabilitation: Focus on underserved populations

"Enhancing Cardiac Rehabilitation Adherence Through Home-Based Rehabilitation and Behavioral Nudges: The ERA Nudge Study Design and Rationale"

BACKGROUND

Cardiac rehabilitation (CR) continues to be under-utilized despite known benefits across the cardiovascular disease spectrum. Unfortunately, despite efforts to augment access, barriers persist in patient access to rehabilitation and ability to participate due to logistical challenges. A choice of home-based CR may present an appealing alternative that circumvents these known obstacles. Similarly, nudge reminders, or messages designed to elicit behavioral change, may improve adherence to CR.

HYPOTHESIS

Providing a choice of home or hospital-based CR, and nudge reminders will improve adherence to CR in an urban safety net population.

DESIGN

The Enhancing Cardiac Rehabilitation Adherence Through Home-Based Rehabilitation and Behavioral Nudges (ERA-Nudge) study utilizes a 2 × 2 factorial design to randomize eligible CR patients to usual care versus choice of home or hospital-based CR, and tailored nudge messages versus generic reminders to encourage healthy behavior. The study assesses the effectiveness of choice of CR location (i.e., home versus hospital) and nudge messages in improving CR adherence. The study also uses an implementation framework to understand reach, adoption, implementation, and maintenance of this approach within the context of real-world care delivery in a pragmatic trial design. The enrollment was completed in May 2023, with a total of 447 patients.

SUMMARY

The ERA-Nudge trial assesses the implementation, effectiveness, and safety of choice in CR location and nudge messaging to improve CR adherence. If successful, this approach can be easily disseminated and may inform future implementations for rehabilitation and other behavioral therapies.

Technology-enabled hybrid cardiac rehabilitation: Qualitative study of healthcare professional and patient perspectives at three cardiac rehabilitation centres in England

Coronary heart disease (CHD) is a leading cause of death in the UK. Clinical guidelines recommend cardiac rehabilitation (CR), including health education, cardiovascular risk reduction advice, physical activity and stress management components. However, uptake of standard in-person, group-based CR is only around 50%. Hybrid cardiac rehabilitation (CR), combining in-person and remote service delivery, may improve CR uptake and reduce inequalities in service access. This study used focus groups and semi-structured interviews to explore staff and patient experiences of using the Active+me REMOTE hybrid CR app, a cloud-based platform providing access to education modules, behaviour change support, live exercise classes, physical activity and health monitoring across three sites in the East of England. Twelve staff and six patients participated. Topic guides explored participants' experiences of delivering or receiving hybrid CR, barriers and facilitators associated with the hybrid CR pathway, and implications for future implementation of Active+me REMOTE. Qualitative data were collected remotely, audio-recorded and independently transcribed. Staff data were analysed deductively, using the Consolidated Framework for Implementation Research (CFIR). Patient data were analysed inductively using thematic analysis. Despite some technical issues and governance delays, Active+me REMOTE was perceived as acceptable, convenient and allowed tailoring of support to meet patients' needs and circumstances. Data upload from wearable devices (blood pressure monitors) allowed staff to monitor patients' progress and empowered patients to direct their recovery. Staff initially felt they should screen patients to ensure that hybrid CR was offered to digitally literate, physically active individuals, although screening became less common as staff familiarity with the app increased. Findings suggest that effective implementation of hybrid CR requires system-level resource to facilitate governance approvals and embed hybrid CR delivery as standard care. Sufficient time must be allowed for staff training and to support patient enrolment to hybrid services. The study was registered on 3/7/2023 (ISRCTN320764).

Health Care Use and Expenditures Associated With Cardiac Rehabilitation Among Eligible Medicare Fee-for-Service Beneficiaries

BACKGROUND

Cardiac rehabilitation (CR) can improve cardiovascular health. We identified whether CR participation was associated with fewer subsequent inpatient hospitalizations and emergency department visits and less Medicare and out-of-pocket expenditures, and whether outcomes varied by amount of participation.

METHODS

This retrospective study used Medicare fee-for-service claims data, including beneficiaries with a CR-qualifying event in 2016. Participants attended ≥2 sessions of CR within 365 days of the event. Propensity score matching was used to identify CR-eligible nonparticipants. Difference-in-differences analyses were used to compare differences in outcomes before (2014-2015) and after (2018-2019; 2-year CR period=2016-2017) the CR period between participants and nonparticipants.

RESULTS

We identified 57 668 CR-eligible beneficiaries after matching, with equal numbers of participants and nonparticipants. Nearly 65% of beneficiaries had a percutaneous coronary intervention, 33.5% had an acute myocardial infarction, 17.5% had a coronary artery bypass graft, and 16.8% had a heart valve repair/replacement. Compared with nonparticipants, participants had 47.6 fewer subsequent annual inpatient hospitalizations per 1000 beneficiaries (95% CI, -58.8 to -36.3) and $1005 lower subsequent annual Medicare expenditures per beneficiary (95% CI, -$1352 to -$659). Compared with no participation, medium participation (12-23 sessions), high participation (24-35 sessions), and CR completion (≥36 sessions) were associated with fewer inpatient hospitalizations and lower Medicare expenditures per year.

CONCLUSIONS

CR was associated with fewer subsequent annual inpatient hospitalizations and lower subsequent annual Medicare expenditures. A higher amount of participation was associated with a further reduction in hospitalizations and expenditures. These findings can inform programs and policies that encourage CR participation.

An eHealth intervention for patients with a low socioeconomic position during their waiting period preceding cardiac rehabilitation: a randomized feasibility study

Aims

Cardiac rehabilitation (CR) shows lower effectiveness and higher dropouts among people with a low socioeconomic position (SEP) compared to those with a high SEP. This study evaluated an eHealth intervention aimed at supporting patients with a low SEP during their waiting period preceding CR.

Methods and results

Participants with a low SEP in their waiting period before CR were randomized into an intervention group, receiving guidance videos, patient narratives, and practical tips, or into a control group. We evaluated adherence (usage metrics), acceptance (modified Usefulness, Satisfaction, and Ease of use questionnaire), and changes in feelings of certainty and guidance between the waiting period's start and end. Semi-structured interviews provided complementary insights. The study involved 41 participants [median interquartile range (IQR) age 62 (14) years; 33 males], with 21 participants allocated to the intervention group, using the eHealth intervention for a median (IQR) duration of 16 (10) days, using it on a median (IQR) of 100% (25) of these days, and viewing 88% of the available messages. Key adherence themes were daily routine compatibility and curiosity. Acceptance rates were 86% for usability, 67% for satisfaction, and 43% for usefulness. No significant effects on certainty and guidance were observed, but qualitative data suggested that the intervention helped to inform and set expectations.

Conclusion

The study found the eHealth intervention feasible for cardiac patients with a low SEP, with good adherence, usability, and satisfaction. However, it showed no effect on feelings of certainty and guidance. Through further optimization of its content, the intervention holds promise to improve emotional resilience during the waiting period.

Exploring Information Needs and Educational Preferences of Individuals Referred to Cardiac Rehabilitation Before Program Start

PURPOSE

To explore information needs and educational preferences of individuals referred to cardiac rehabilitation (CR) before program start.

METHODS

This cross-sectional study was conducted from June 2023 to February 2024. Referred patients were contacted via email, which included a link to a website providing information about the CR program, and instructional videos. Data were collected through surveys that assessed health literacy levels, information needs (using the short version of the Information Needs in CR), frequently asked questions, delivery preferences, and engagement/satisfaction with educational resources.

RESULTS

Throughout the study period, the CR center received 2571 referrals, of which 881 individuals were eligible for the study, and 467 (mean age 66.4 ± 12.2 years; 36% women) consented and completed questionnaires. Information needs were highest for CR and diagnosis/treatment and lowest for nutrition and risk factors. The study revealed significant differences in the perceived importance of information needs across various sociodemographic and clinical characteristics, including age ( P = .01), educational level ( P = .009), work status ( P = .04), main reason for CR referral ( P < .001), and health literacy ( P = .02). Moreover, participants identified key areas of interest and concern related to their CR journey. These included inquiries about safe exercise initiation, pre-stress test instructions, and personalized exercise plans, among others. It was also observed that the majority of participants engaged with the educational materials provided and indicated high levels of satisfaction.

CONCLUSION

This study revealed patient preferences regarding educational content, delivery format, and areas of interest/concern related to CR prior to program start, providing valuable insights for improving the delivery and effectiveness of such programs.

Reducing dropout rates in cardiac rehabilitation among cardiac patients in a vulnerable situation: systematic development and feasibility testing of the Heart Priority Programme

BACKGROUND

Despite advancements in reducing cardiovascular disease, it remains a major health concern. Cardiac rehabilitation (CR) has a positive impact on morbidity, mortality, and functioning, but faces high dropout rates especially among vulnerable patients, due to social inequalities and insufficiently tailored interventions. To address this, we developed the Heart Priority Programme targeting and supporting cardiac patients at risk of dropout. This study outlines the development of the Heart Priority Programme and share findings from a feasibility test.

METHODS

An iterative three-stage process involving cardiac patients and healthcare professionals from three community healthcare services, guided the development of the programme. Stage 1 included reviewing evidence, consulting stakeholders, and observing practice. In stage 2, a project-group of researchers and healthcare professionals was established to co-produce the programme. Stage 3 included field-testing and local adaptions. Subsequently, the programme was feasibility tested in a single-arm follow-up study across two community healthcare services. Over six months, process data on implementation, acceptability, and mechanism of impact were gathered.

RESULTS

The Heart Priority Programme was development from January 2023 to June 2023, comprising two main parts: 1) an evidence-based identification form with 13 risk factors to identify patients at risk of dropout (referred to as priority patients), and 2) an add-on intervention targeted these patients with three core elements-assigning a contact person, systematic communication, and follow-up. During a six-month feasibility phase, 260 patients were included. Of these, 91 (35%) were identified as priority patients. CR teams found that the programme was relevant, easy to integrate into daily workflow, and applicable in practice. Patient consultations yielded positive feedback on the three core elements of the add-on intervention.

CONCLUSIONS

This paper outlines the development and feasibility test of the Heart Priority Programme, co-produced to identify, and support priority patients. The programme, developed through a three-stage iterative co-production process, was found relevant and easy to implement in community healthcare services. CR teams valued its structured approach to supporting priority patients, and patients found it aligned with their needs. Although initial results are promising, further research is needed to evaluate the programme's effectiveness and suitability for widespread implementation.

Cardiac rehabilitation: the gateway for secondary prevention

Cardiac rehabilitation (CR) is a multidisciplinary supervised programme which typically consists of tailored exercise and education on lifestyle management and risk factor modification in cardiac patients. Participation in CR reduces morbidity and mortality, while improving quality of life following major cardiovascular events. Despite the benefits of CR, it is underutilised, generally in the 20%-30% range for eligible patients. Participation and adherence rates are particularly suboptimal in vulnerable populations, such as those of lower socioeconomic status and women. Interventions such as automated referral to CR or hybrid/virtual programmes can increase enrolment to CR. This review summarises the components of CR and provides recommendations for providers regarding participation and adherence. To better engage a larger proportion of CR-eligible patients, CR programmes may need to expand or adjust ways to deliver secondary prevention.

Knowledge, attitude, and perception of exercises among post-hematopoietic stem cell transplant patients: A cross-sectional study

Exercise rehabilitation is crucial for the recovery after hematopoietic stem cell transplantation (HSCT). This study aimed to investigate knowledge, attitude, and perception (KAP) of exercise among post-HSCT patients. This cross-sectional study was conducted at Zhujiang Hospital, Southern Medical University between January 2020 and December 2022 among post-HSCT patients, using a self-designed questionnaire. A total of 192 patients were included, with the mean age of 37.90 ± 11.96 years; 116 (60.42%) reported to exercise before. The mean KAP scores were 9.22 ± 2.05 (possible range: 0-12), 43.51 ± 5.47 (possible range: 12-60) and 51.79 ± 7.45 (possible range: 15-75), respectively. Patients previously inactive in exercise exhibited significant differences in KAP scores from active patients: attitude total score, positive attitude, perception total score, willingness to exercise, aerobic exercise, breathing training (all P < .001), with a noteworthy distinction in resistance exercise (P = .018). According to structural equation modeling, perception was directly influenced by knowledge (β = 0.87, P < .001), attitude (β = 0.26, P = .007), and exercise habits (β = 3.36, P = .001), as well as indirectly by education (β = 0.44, P = .010) and knowledge (β = 0.18, P = .029). Post-HSCT patients had adequate knowledge, moderate attitude and perception of exercises, even 1 year after HSCT. Patients inactive in exercises exhibited significant differences in knowledge and exercise perception from active patients. Healthcare professionals should tailor education, target attitude, and personalize exercise plans to facilitate effective recovery post-HSCT.

Differential effects of cigarette smoking on cardiovascular disease in females: A narrative review and call to action

OBJECTIVE

Cigarette smoking continues to be a major driver in the incidence and progression of cardiovascular disease (CVD). As females become an increasingly larger fraction of those who smoke it is imperative that the sex-specific effects of smoking be further explored and acted upon.

METHODS

This narrative review describes current evidence on the differential effects of smoking on CVD in females and the need to improve treatment.

RESULTS

Evidence to date suggests that smoking has disproportionately negative effects on the cardiovascular (CV) system in females, especially in those who are younger. Usually, the onset of CVD is later in females than males, but smoking decreases or eliminates this gap. Females are also more likely to develop types of CVD closely tied to smoking, such as ST-elevated myocardial infarctions, with even higher rates among those who are younger. Possible mechanisms for these worse outcomes in females include a complex interplay between nicotine, other products of combusted cigarettes, and hormones. Sex differences also exist in treatment for smoking. In females, Varenicline appears more effective than either Bupropion or nicotine replacement therapy while in males, all three therapies show similar efficacy. Disparities in smoking are also apparent in secondary prevention settings. Females and males are entering secondary prevention with equal rates of smoking, with potentially higher levels of exposure to the byproducts of smoking in females.

CONCLUSIONS

These disproportionately negative outcomes for females who smoke require additional research and these persisting rates of smoking suggest a need for female-specific approaches for treating smoking.

Efficacy of Wearable Single-Lead ECG Monitoring during Exercise Stress Testing: A Comparative Study

BACKGROUND AND OBJECTIVES

Few comparative studies have evaluated wearable single-lead electrocardiogram (ECG) devices and standard multi-lead ECG devices during exercise testing. This study aimed to validate the accuracy of a wearable single-lead ECG monitor for recording heart rate (HR) metrics during graded exercise tests (GXTs).

METHODS

A cohort of 50 patients at a tertiary hospital underwent GXT while simultaneously being equipped with wearable single- and conventional multi-lead ECGs. The concordance between these modalities was quantified using the intraclass correlation coefficient and Bland-Altman plot analysis.

RESULTS

The minimum and average HR readings between the devices were generally consistent. Parameters such as ventricular ectopic beats and supraventricular ectopic beats showed strong agreement. However, the agreement for the Total QRS and Maximum RR was not sufficient. HR measurements across different stages of the exercise test showed sufficient agreement. Although not statistically significant, the standard multi-lead ECG devices exhibited higher noise levels compared to the wearable single-lead ECG devices.

CONCLUSIONS

Wearable single-lead ECG devices can reliably monitor HR and detect abnormal beats across a spectrum of exercise intensities, offering a viable alternative to traditional multi-lead systems.

Use of a Liaison-Mediated Referral Strategy and Participation in Cardiac Rehabilitation After Percutaneous Coronary Intervention

BACKGROUND

Cardiac rehabilitation (CR) improves outcomes following percutaneous coronary intervention (PCI) but remains underutilized. A liaison-mediated referral (LMR), where a health care professional explains CR's benefits, addresses barriers to participation, and places a referral before discharge, may promote CR use. Our objective was to assess the impact of an LMR on CR participation after PCI.

METHODS

This was a retrospective study of patients who underwent PCI across 48 hospitals in Michigan between January 2021 and April 2022 and referred to CR before discharge. Clinical registry data were linked to administrative claims to identify the primary outcome, CR participation, defined as ≥1 CR session within 90 days of discharge. Bayesian hierarchical logistic regression was used to compare CR participation between patients with and without an LMR. For the secondary outcome, frailty proportional hazard modeling compared days elapsed between discharge and first CR session between liaison cohorts.

RESULTS

Among 9023 patients referred to CR after PCI, 4323 (47.9%) underwent an LMR (mean age, 69.3 [SD=11] years; 68.3% male) and 3390 (36.7%) attended ≥1 CR session within 90 days of discharge. The LMR cohort had a higher unadjusted CR participation rate (43.1% [95% CI, 41.5%-44.6%] versus 32.4% [95% CI, 31.1%-33.8%]; P<0.001), a higher adjusted odds ratio of attending ≥1 CR session (adjusted odds ratio, 1.21; 95% credible interval, 1.07-1.38), and a shorter delay in attending the first CR session compared with the non-LMR cohort (28 [interquartile range, 19-42] versus 33 [interquartile range, 21-47] days; P<0.001).

CONCLUSIONS

An LMR was associated with higher odds of CR participation and may mitigate delays in CR enrollment. This referral strategy may improve CR participation and patient outcomes after PCI.

Improving Cardiac Rehabilitation Adherence in Patients With Lower Socioeconomic Status: A Randomized Clinical Trial

Importance

Participation in cardiac rehabilitation is associated with significant decreases in morbidity and mortality. Despite the proven benefits, cardiac rehabilitation is severely underutilized in certain populations, specifically those with lower socioeconomic status (SES).

Objective

To assess the efficacy of early case management and/or financial incentives for increasing cardiac rehabilitation adherence among patients with lower SES.

Design, Setting, and Participants

This randomized clinical trial enrolled patients from December 2018 to December 2022. Participants were followed up for 1 year with assessors and cardiac rehabilitation staff blinded to study condition. Patients with lower SES with a cardiac rehabilitation-qualifying diagnosis (myocardial infarction, coronary artery bypass graft, percutaneous coronary intervention, heart valve replacement/repair, or stable systolic heart failure) were recruited. Then patients attended one of 3 cardiac rehabilitation programs at 1 university or 2 community-based hospitals. A consecutively recruited sample was randomized and stratified by age (<57 vs ≥57 years) and smoking status (current smoker vs nonsmoker or former smoker).

Intervention

Participants were randomized 2:3:3:3 to either a usual care control, case management starting in-hospital, financial incentives for completing cardiac rehabilitation sessions, or both interventions (case management plus financial incentives). Interventions were in place for 4 months following informed consent.

Main Outcomes and Measures

The main outcome was cardiac rehabilitation adherence (proportion of patients completing ≥30 sessions). The a priori hypothesis was that interventions would improve adherence, with the combined intervention performing best.

Results

Of 314 individuals approached, 11 were ineligible, and 94 declined participation. Of the 209 individuals who were randomized, 17 were withdrawn. A total of 192 individuals (67 [35%] female; mean [SD] age, 58 [11] years) were included in the analysis. Interventions significantly improved cardiac rehabilitation adherence with 4 of 36 (11%), 13 of 51 (25%), 22 of 53 (42%), and 32 of 52 (62%) participants completing at least 30 sessions in the usual care, case management, financial incentives, and case management plus financial incentives conditions, respectively. The financial incentives and case management plus financial incentives conditions significantly improved cardiac rehabilitation adherence vs usual care (adjusted odds ratio [AOR], 5.1 [95% CI, 1.5-16.7]; P = .01; AOR, 13.2 [95% CI, 4.0-43.5]; P < .001, respectively), and the case management plus financial incentives condition was superior to both case management or financial incentives alone (AOR, 5.0 [95% CI, 2.1-11.9]; P < .001; AOR, 2.6 [95% CI, 1.2-5.9]; P = .02, respectively). Interventions were received well by participants: 86 of 105 (82%) in the financial incentives conditions earned at least some incentives, and 96 of 103 participants (93%) assigned to a case manager completed the initial needs assessment.

Conclusion and Relevance

In this randomized clinical trial, financial incentives improved cardiac rehabilitation adherence in a population with higher risk and lower SES with additional benefit from adding case management.

The Impact of Education on Patients Eligible for Cardiac Rehabilitation and Factors Contributing to Declining Participation in Turkish Society: Are Patients Aware of Cardiac Rehabilitation?

OBJECTIVE

Despite their effectiveness, cardiac rehabilitation (CR) programs have low participation and adherence rates. CR participation and adherence are directly related to the social, economic, cultural, and geographical characteristics of the society. Therefore, our study aimed to investigate the reasons behind low participation in CR within Turkish society, as well as the barriers that restrict participation despite educational efforts.

METHOD

The research was conducted with participants who were over 18 years of age, had any history of heart disease, and had been hospitalized in the last year. The patients' medical history, chronic diseases, demographics, habits, employment and income status, educational status, and approaches to CR were surveyed. Additionally, patients who still did not consider participating in CR after receiving information were asked about the reasons for their decisions.

RESULTS

Although 95.6% of patients were eligible for CR, 91.9% of them were previously unaware of this treatment option. After being informed, 29.4% of patients agreed to participate in CR. The most common reasons for not participating after receiving information were as follows: three days a week is too much (21.9%); this place is far away, but if it were closer, I would come (18.1%); I can't come on weekdays (15.6%); and I would come if someone brought me (14.4%).

CONCLUSION

We observed that the participation rate in CR increased from 0% to 29.4% after receiving information. Furthermore, it was determined that the CR schedule and transportation were significant factors influencing participation.

Cardiac rehabilitation for heart failure: progress and gaps in evidence and policy

PURPOSE OF REVIEW

This review synthesizes recent research on the efficacy, optimal design, and delivery methods of cardiac rehabilitation tailored to heart failure patients. Despite established benefits, cardiac rehabilitation referral and access disparities persist, necessitating elucidation of limitations and solutions.

RECENT FINDINGS

Exercise-based cardiac rehabilitation improves long-term mortality and hospitalization rates but not short-term mortality. cardiac rehabilitation further enhances quality of life and medical therapy adherence. However, cardiac rehabilitation relies on in-person delivery, presenting access barriers exacerbated during COVID-19. Significant geographic disparities exist, with analyses indicating current capacity only serves 45% of eligible US adults even if fully utilized. Referral rates also lag, disproportionately affecting women and minority groups. Research increasingly focuses on home-based and digital therapeutics modalities to expand reach, with evidence demonstrating comparable improvements across settings. Protocols and research center on heart failure with reduced ejection fraction (HFrEF), despite growing heart failure with preserved ejection fraction (HFpEF) prevalence.

SUMMARY

Increasing referrals through standardized procedures and addressing multifactorial geographic, economic, and capacity limitations are imperative to ensure equitable cardiac rehabilitation access. Broadening HFpEF rehabilitation research and care standards also constitutes a critical practice gap requiring alignment with projected epidemiologic shifts. Advancing patient-centered, evidence-based solutions can promote rehabilitation as essential secondary prevention for wider cardiac populations.

Temporal trends in admission for cardiac rehabilitation after an acute coronary syndrome in France from 2009 to 2021: Persistent sex, age and social disparities

BACKGROUND

Cardiac rehabilitation after an acute coronary syndrome is recommended to decrease patient morbidity and mortality and to improve quality of life.

AIMS

To describe time trends in the rates of patients undergoing cardiac rehabilitation after an acute coronary syndrome in France from 2009 to 2021, and to identify possible disparities.

METHODS

All patients hospitalized for acute coronary syndrome in France between January 2009 and June 2021 were identified from the national health insurance database. Cardiac rehabilitation attendance was identified within 6 months of acute coronary syndrome hospital discharge. Age-standardized cardiac rehabilitation rates were computed and stratified for sex and acute coronary syndrome subtypes (ST-segment elevation and non-ST-segment elevation). Patient characteristics and outcomes were described and compared. Factors independently associated with cardiac rehabilitation attendance were identified.

RESULTS

In 2019, among 134,846 patients with an acute coronary syndrome, 22.3% underwent cardiac rehabilitation within 6 months of acute coronary syndrome hospital discharge. The mean age of patients receiving cardiac rehabilitation was 62 years. The median delay between acute coronary syndrome hospitalization and cardiac rehabilitation was 32 days, with about 60% receiving outpatient cardiac rehabilitation. Factors significantly associated with higher cardiac rehabilitation rates were male sex, younger age (35-64 years), least socially disadvantaged group, ST-segment elevation, percutaneous coronary intervention and coronary artery bypass graft. Between 2009 and 2019, cardiac rehabilitation rates increased by 40% from 15.9% to 22.3%. Despite greater upward trends in women, their cardiac rehabilitation rate was significantly lower than that for men (14.8% vs. 25.8%). In 2020, cardiac rehabilitation attendance dropped because of the coronavirus disease 2019 pandemic.

CONCLUSIONS

Despite the health benefits of cardiac rehabilitation, current cardiac rehabilitation attendance after acute coronary syndrome remains insufficient in France, particularly among the elderly, women and socially disadvantaged people.

Lower-Socioeconomic Status Patients Have Extremely High-Risk Factor Profiles on Entry to Cardiac Rehabilitation

PURPOSE

Patients with lower socioeconomic status (SES) have higher rates of cardiovascular events, yet are less likely to engage in secondary prevention such as cardiac rehabilitation (CR). Given the low number of lower-SES patients entering CR, characterization of this population has been difficult. Our CR program specifically increased recruitment of lower-SES patients, allowing for careful comparison of medical, psychosocial, and behavioral risk factors between lower- and higher-SES patients eligible for secondary prevention.

METHODS

Demographic and clinical characteristics were prospectively gathered on consecutive individuals entering phase 2 CR from January 2014 to December 2022. Patients were classified as lower SES if they had Medicaid insurance. Statistical methods included chi-square and nonpaired t tests. A P value of <.01 was used to determine significance.

RESULTS

The entire cohort consisted of 3131 individuals. Compared with higher-SES patients, lower-SES individuals (n = 405; 13%) were a decade younger (57.1 ± 10.4 vs 67.2 ± 11.2 yr), 5.8 times more likely to be current smokers (29 vs 5%), 1.7 times more likely to have elevated depressive symptoms, and significantly higher body mass index, waist circumference, and glycated hemoglobin A 1c , with more abnormal lipid profiles (all P s < .001). Despite being a decade younger, lower-SES patients had lower measures of cardiorespiratory fitness and self-reported physical function (both P s < .001).

CONCLUSION

Lower-SES patients have a remarkably prominent high-risk cardiovascular disease profile, resulting in a substantially higher risk for a recurrent coronary event than higher-SES patients. Accordingly, efforts must be made to engage this high-risk population in CR. It is incumbent on CR programs to ensure that they are appropriately equipped to intervene on modifiable risk factors such as low cardiorespiratory fitness, obesity, depression, and smoking.

The effect of cardiac rehabilitation on cardiopulmonary function after coronary artery bypass grafting: A systematic review and meta-analysis

We carried out a meta-analysis on the effect of cardiac rehabilitation (CR) on cardiopulmonary function after coronary artery bypass grafting (CABG). Four databases were searched for studies comparing CR with control. A random-effects model was used to pool mean difference (MD). The meta-analysis showed an increase in peak oxygen consumption (peak VO2) (MD = 1.93 mL/kg/min, p = 0.0006), and 6-min walk distance (6MWD) (MD = 59.21 m, p < 0.00001), and a decrease in resting heart rate (resting HR) (MD = 5.68 bpm, p < 0.0001) in the CR group. The subgroup analysis revealed aerobic exercise could further improve resting HR and peak HR, and physical/combination with aerobic exercise could further increase 6MWD. The improvement of peak VO2, workload, resting HR, peak HR, and 6MWD regarding CR performed within one week after CABG is greater than that one week after CABG. CR after CABG can improve the cardiopulmonary function, which is reflected by the improvement of peak VO2, 6MWD, and resting HR.

Impact of cardiac rehabilitation on cardiovascular event in Korea

This study aimed to evaluate the effects of cardiac rehabilitation (CR) on major adverse cardiac events (MACE) among patients who underwent PCI procedure. We used data from the electronic medical records (EMR) of a tertiary hospital in Seoul, Korea, from January 2014 to February 2020. Data from 2988 patients who had experienced their first acute coronary syndrome (ACS) and had undergone percutaneous coronary intervention (PCI) were included during the study period. we classified patients into CR participants and non-participants based on their participation in the cardiac rehabilitation (CR) program within 30 days after discharge. And the outcome was the incidence of myocardial infarction (MI) and stroke within 1 year after discharge. The association between participation in CR and risk of developing MACE was evaluated using the Cox proportional hazards model. Patients who achieved CR after undergoing PCI were at a lower risk of developing MI (HR 0.68, CI 0.53-0.86). There was no significant association between participation in CR and the incidence of stroke. Among patients who had more than three stenotic vessels, the risk of developing MI within 1 year of discharge was reduced in CR users compared to non-users (3 or more stenosis vessels: HR 0.55, CI 0.35-0.86). Among patients who used two and more stents during PCI procedures, the risk of developing MI within 1 year of discharge was reduced in CR users compared to non-users (2 and more stents: HR 0.54, CI 0.35-0.85). Among people diagnosed with ACS and receiving PCI, patients who participated in CR within one month of discharge reduced risk of developing MI. Our study reinforced the current evidence on the effect of CR among patients receiving PCI and presented the expansion and enhancement of the CR program.

Clinical challenges facing patient participation in cardiac rehabilitation: cigarette smoking

INTRODUCTION

Cardiac rehabilitation (CR) is highly effective at reducing morbidity and mortality. However, CR is underutilized, and adherence remains challenging. In no group is CR attendance more challenging than among patients who smoke. Despite being more likely to be referred to CR, they are less likely to enroll, and much more likely to drop out. CR programs generally do not optimally engage and treat those who smoke, but this population is critical to engage given the high-risk nature of continued smoking in those with cardiovascular disease.

AREAS COVERED

This review covers four areas relating to CR in those who smoke. First, we review the evidence of the association between smoking and lack of participation in CR. Second, we examine how smoking has historically been identified in this population and propose objective screening measures for all patients. Third, we discuss the optimal treatment of smoking within CR. Fourth, we review select populations within those who smoke (those with lower-socioeconomic status, females) that require additional research and attention.

EXPERT OPINION

Smoking poses a challenge on multiple fronts, being a significant predictor of future morbidity and mortality, as well as being strongly associated with not completing the secondary prevention program (CR) that could benefit those who smoke the most.

Sex differences in cardiac rehabilitation barriers among non-enrollees in the context of lower gender equality: a cross-sectional study

BACKGROUND

Despite the benefits of cardiac rehabilitation (CR), it remains under-utilized, particularly by women. This study compared CR barriers between non-enrolling men and women in Iran, which has among the lowest gender equality globally.

METHODS

In this cross-sectional study, CR barriers were assessed via phone interview in phase II non-attenders from March 2017 to February 2018 with the Persian version of the Cardiac Rehabilitation Barriers Scale (CRBS-P). T-tests were used to compare scores, with each of 18 barriers scored out of 5, between men and women.

RESULTS

357 (33.9%) of the sample of 1053 were women, and they were older, less educated and less often employed than men. Total mean CRBS scores were significantly greater in women (2.37 ± 0.37) than men (2.29 ± 0.35; effect size[ES] = 0.08, confidence interval[CI]: 0.03-0.13; p < 0.001). The top CR barriers among women were cost (3.35; ES = 0.40, CI:0.23-0.56; P < 0.001), transportation problems (3.24; ES = 0.41, CI:0.25-0.58; P < 0.001), distance (3.21; ES = 0.31, CI:0.15-0.48; P < 0.001), comorbidities (2.97; ES = 0.49, CI:0.34-0.64; P < 0.001), low energy (2.41; ES = 0.29, CI:0.18-0.41; P < 0.001), finding exercise as tiring or painful (2.22; ES = 0.11, CI:0.02-0.21; P = 0.018), and older age (2.27; ES = 0.18, CI:0.07-0.28; P = 0.001). Men rated "already exercise at home or in community" (2.69; ES = 0.23, CI:0.1-0.36; P = 0.001), time constraints (2.18; ES = 0.15, CI:0.07-0.23; P < 0.001) and work responsibilities (2.24; ES = 0.16, CI:0.07-0.25; P = 0.001) as greater CR barriers than women.

CONCLUSION

Women had greater barriers to CR participation than men. CR programs should be modified to address women's needs. Home-based CR tailored to women's exercise needs and preferences should be considered.

Financial incentives and case management to improve cardiac rehabilitation participation among patients with lower socio-economic status: Rationale and protocol for a randomized controlled trial

BACKGROUND

Participation in phase 2 cardiac rehabilitation (CR) is associated with significant decreases in morbidity and mortality. Unfortunately, attendance at CR is not optimal and certain populations, such as those with lower-socioeconomic status (SES), are less likely to participate. In order to remedy this disparity we have designed a trial to examine the efficacy of early case management and/or financial incentives for increasing CR participation among lower-SES patients.

METHODS

We will employ a randomized controlled trial with a sample goal of 209 patients who will be randomized 2:3:3:3 to either a usual care control, to receive a case manager starting in-hospital, to receive financial incentives for completing CR sessions, or to receive both interventions.

RESULTS

Treatment conditions will be compared on attendance at CR and end-of-intervention (four months) improvements in cardiorespiratory fitness, executive function, and health-related quality of life. The primary outcome measures for this project will be number of CR sessions completed and the percentage who complete ≥30 sessions. Secondary outcomes will include improvements in health outcomes by condition, as well as the cost-effectiveness of the intervention with a focus on potential reductions in emergency department visits and hospitalizations. We hypothesize that either intervention will perform better than the control and that the combination of interventions will perform better than either alone.

CONCLUSIONS

This systematic examination of interventions will allow us to test the efficacy and cost-effectiveness of approaches that have the potential to increase CR participation substantially and significantly improve health outcomes among patients with lower-SES.

Ethnic Minorities' Experiences of Cardiac Rehabilitation: A Scoping Review

Cardiac rehabilitation (CR) can improve cardiovascular risk factors, decrease cardiac mortality, and promote healthy lifestyle behaviours. However, services remain underutilized by groups of ethnic minorities. The purpose of the study was to identify patients' personal CR experiences to identify the differences CR makes towards minorities' lifestyle. An initial electronic search was performed in 2021 for papers ranging from 2008-2020 across specific databases, including PubMed, EMBASE, APA PsycINFO, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Medline. Google Scholar was also used to supplement the search process and to identify studies performed within grey literature. A total of 1230 records were screened, of which 40 were assessed for eligibility. The final sample consisted of seven qualitative design studies that were identified for inclusion in this review. Based on patient personal experiences, this review identified that ethnic minorities continue to remain disadvantaged when accessing healthcare interventions, primarily as a result of cultural behaviours, linguistic barriers, socioeconomic status, religious and fatalistic beliefs, and low physician referral rates. More research is needed to elucidate this phenomenon and address these factors faced by ethnic minorities.

Racial and Ethnic Differences in Cardiac Rehabilitation Participation: Effect Modification by Household Income

Background

Cardiac rehabilitation (CR) is associated with improved cardiovascular outcomes. Racial and ethnic differences in CR have been identified, but whether income may attenuate these disparities remains unknown. We evaluated (1) racial/ethnic differences in CR participation in a contemporary sample of insured US adults, and (2) assessed how household income modifies associations between race or ethnicity and CR participation.

Methods and Results

We identified 107 199 individuals with a CR‐qualifying diagnosis between January 1, 2016 and December 31, 2018 in Optum’s de‐identified Clinformatics database. We evaluated associations between race or ethnicity and participation in CR, and assessed interaction between race or ethnicity and annual household income. The mean±SD age of all participants was 70.4±11.6 years; 37.4% were female and 76.0% were White race. Overall, 28 443 (26.5%) attended ≥1 CR sessions. After adjustment, compared with White individuals, the probability of attending CR was 31% lower for Asian individuals (95% CI, 27%–36%), 19% lower for Black individuals (95% CI, 16%–22%), and 43% lower for Hispanic individuals (95% CI, 40%–45%), all P<0.0001. The time to CR attendance was also significantly longer for Asian, Black, and Hispanic individuals. Associations between race or ethnicity and attendance at CR differed significantly across household income categories (P interaction=0.0005); however, Asian, Black, and Hispanic individuals were less likely to attend CR at all incomes.

Conclusions

In a geographically and racially diverse cohort, participation in CR was low overall, and was lowest among Asian, Black, and Hispanic candidates. Household income may impact the link between race or ethnicity and attendance at CR, but substantial racial and ethnic disparities exist across incomes.
