Cardiac rehabilitation participation in underserved populations. Minorities, low socioeconomic, and rural residents

Care for Atrial Fibrillation and Outcomes in Rural Versus Urban Communities in the United States: A Systematic and Narrative Review

Atrial fibrillation (AF) is the most common sustained arrhythmia and associated with increased morbidity and mortality. Differences have been identified between medical care delivered in urban and rural settings, and rurality-based disparities may exist in AF care. We performed a systematic review investigating the effect of rurality on AF care and outcomes in the United States. PubMed was queried for entries on AF and rurality: ("atrial fibrillation" OR "atrial flutter") AND ("rural" OR "urban" OR "rurality" OR "metro" OR "metropolitan") AND ("united states" OR "US" OR "U.S.") published up to September 24, 2023. Anticoagulation, rhythm control, settings of care, outcomes, and all-cause mortality were reviewed in relevant studies. The search identified 395 total articles. After screening, 14 relevant articles were included in the review. These studies ranged from 1993 to 2020 and analyzed approximately 41.7 million AF patient encounters. The use of catheter ablation for AF per electrophysiologist was similar across the rural-urban spectrum. Patients with AF and rural residence were less likely to receive a direct oral anticoagulant and more likely to remain on warfarin (relative risk, 0.90 [95% CI, 0.88-0.92]). Patients in rural communities were less likely to receive non-emergent AF care (odds ratio [OR], 0.96 [95% CI, 0.93-0.98]). In-hospital mortality for patients with AF admitted to rural hospitals was higher than urban hospitals (OR, 1.19 [95% CI, 1.01-1.39)]. Measurable differences exist in both treatments and outcomes of patients with AF between rural and urban settings in the United States. These differences should inform future investigations and strategies to improve health in people with AF.

Evaluating for Health Equity in a Safety Net Hospital: Socioeconomic Status, Adherence, and Outcomes in Cardiac Rehabilitation

PURPOSE

Uncovering the racial/ethnic health disparities that exist within cardiovascular medicine offers potential to mitigate treatment gaps that might affect outcomes. Socioeconomic status (SES) may be a more appropriate underlying factor to assess these disparities. We aimed to evaluate whether adherence, attendance, and outcomes in cardiac rehabilitation are associated with SES in a safety net hospital.

METHODS

We analyzed 542 patients in a retrospective cohort study of the Cardiac Rehabilitation Program at Boston Medical Center from 2016 to 2019. Enrollees had a mean age of 59.4 years, 34% were female, 42% Black, and 12% Hispanic. The zip codes of each enrollee were used to obtain their area deprivation index (ADI). The ADI reflects income, education, employment, and housing quality within a given zip code. Associations between ADI and adherence and attendance rate were evaluated while controlling for covariates. Secondary outcomes included associations of ADI with change in exercise capacity, low density lipoprotein cholesterol, weight, quality of life, nutrition, and depression scores.

RESULTS

We applied logistic regression to examine the association between adherence and ADI with adjustment on the covariates. The attendance rate was analyzed with negative binomial regression with percent of sessions attended as prescribed as a dependent variable and adjusted on the same covariates. The primary outcome revealed no association for ADI with adherence to cardiac rehabilitation (OR = 0.91: 95% CI, 0.74-1.12) or attendance rate (RR = 0.91: 95% CI, 0.80-1.04). Utilizing multiple linear regression, secondary outcomes improved among patients regardless of ADI.

CONCLUSIONS

We found equity in our cardiac rehabilitation program outcomes despite SES.

Implementation of a Clinical Decision Support Tool to Improve Cardiac Rehabilitation Referral

PURPOSE

Inadequate referral to cardiac rehabilitation (CR) is a major barrier to CR participation. We investigated the implementation of a clinical decision support (CDS) tool on improving CR referral for patients hospitalized with acute myocardial infarction (AMI) at an academic medical center.

METHODS

We developed a CDS tool that identified patients admitted with AMI and reminded physicians to refer patients to CR. We used multivariable-adjusted logistic regression to evaluate predictors of CR referral prior to the CDS tool. We then conducted an interrupted time series (ITS) analysis on CR referral rates before and after intervention.

RESULTS

A total of 1985 patients admitted with acute MI from December 2014 through March 2023 were included. Prior to CDS implementation, 1218 of 1657 patients (74%) were referred to CR. Multivariable-adjusted logistic regression demonstrated that ST-segment elevation myocardial infarction on arrival (OR = 1.70: 95% CI, 1.29-2.23, P < .001) and percutaneous coronary intervention during the hospitalization (OR = 2.25: 95% CI, 1.60-3.15, P < .001) were associated with a higher odds of CR referral. After implementation of the CDS tool, 308 of 328 patients (94%) received CR referrals. An ITS analysis demonstrated that the increase in CR referral from 74-94% after the CDS tool was highly significant (P < .01).

CONCLUSIONS

The implementation of a CDS tool reminding physicians to refer patients with AMI to CR markedly improved CR referral rates at our institution. These findings are important for institutions seeking to improve outcomes in patients with AMI.

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.

Demographic trends and disparities in mortality related to coexisting heart failure and diabetes mellitus among older adults in the United States between 1999 and 2020: A retrospective population-based cohort study from the CDC WONDER database

Background

Heart Failure (HF) and Diabetes Mellitus (DM) often coexist, and each condition independently increases the likelihood of developing the other. While there has been concern regarding the increasing burden of disease for both conditions individually over the last decade, a comprehensive examination of mortality trends and demographic and regional disparities needs to be thoroughly explored in the United States (US).

Methods

This study analyzed death certificates from the CDC WONDER database, focusing on mortality caused by the co-occurrence of HF and DM in adults aged 75 and older from 1999 to 2020. Age-adjusted mortality rates (AAMRs) and annual percent changes (APCs) were computed and categorized by year, gender, race, census region, state, and metropolitan status.

Results

A total of 663,016 deaths were reported in patients with coexisting HF and DM. Overall, AAMR increased from 154.1 to 186.1 per 100,000 population between 1999 and 2020, with a notable significant increase from 2018 to 2020 (APC: 11.30). Older men had consistently higher AAMRs than older women (185 vs. 135.4). Furthermore, we found that AAMRs were highest among non-Hispanic (NH) American Indian or Alaskan natives and lowest in NH Asian or Pacific Islanders (214.4 vs. 104.1). Similarly, AAMRs were highest in the Midwestern region and among those dwelling in non-metropolitan areas.

Conclusions

Mortality from HF and DM has risen significantly in recent years, especially among older men, NH American Indian or Alaska Natives, and those in non-metropolitan areas. Urgent policies need to be developed to address these disparities and promote equitable healthcare access.

A Dual-Modality Home-Based Cardiac Rehabilitation Program for Adults With Cardiovascular Disease: Single-Arm Remote Clinical Trial

BACKGROUND

Cardiac rehabilitation (CR) is a safe, effective intervention for individuals with cardiovascular disease (CVD). However, a majority of eligible patients do not complete CR. Growing evidence suggests that home-based cardiac rehabilitation (HBCR) programs are comparable in effectiveness and safety with traditional center-based programs. More research is needed to explore different ways to deliver HBCR programs to patients with CVD.

OBJECTIVE

We aimed to assess the feasibility and impact of a digital HBCR program (RecoveryPlus.Health) that integrates both telehealth and mHealth modalities on functional exercise capacity, resting heart rate, and quality of life among adults with CVD.

METHODS

This 12-week prospective, single-arm remote clinical trial used a within-subject design. We recruited adults with CVD (aged ≥40 years) from the community with a CR-eligible diagnosis (stable angina pectoris, myocardial infarction, and heart failure) between May and August 2023. All enrolled patients referred to the RPH clinic in Roanoke, Texas, were included. The care team provided guideline-concordant CR services to study participants via two modalities: (1) a synchronous telehealth exercise training through videoconferencing; and (2) an asynchronous mobile health (mHealth) coaching app (RPH app). Baseline intake survey, electronic health record, and app log data were used to extract individual characteristics, care processes, and platform engagement data. Feasibility was measured by program completion rate and CR service use. Efficacy was measured by changes in the 6-minute walk test, resting heart rate, and quality of life (12-Item Short-Form Health Survey) before and after the 12-week program. Paired t tests were used to examine pre- and postintervention changes in the outcome variables.

RESULTS

In total, 162 met the inclusion criteria and 75 (46.3%) consented and were enrolled (mean age 64, SD 10.30 years; male: n=37, 49%; White: n=46, 61%). Heart failure was the most common diagnosis (37/75, 49%). In total, 62/75 (83%) participants completed the 12-week study and used the telehealth modality with 9.63 (SD 3.33) sessions completed, and 59/75 (79%) used the mHealth modality with 10.97 (SD 11.70) sessions completed. Post intervention, 50/62 (81%) participants' performance in the 6-minute walk test had improved, with an average improvement of 40 (SD 63.39) m (95% CI 25.6-57.1). The average 12-Item Short-Form Health Survey's physical and mental summary scores improved by 2.7 (SD 6.47) points (95% CI 1.1-4.3) and 2.2 (SD 9.09) points (95% CI 0.1-4.5), respectively. There were no changes in resting heart rate and no exercise-related adverse events were reported.

CONCLUSIONS

The RecoveryPlus.Health digital HBCR program showed feasibility and efficacy in a group of nationally recruited patients with CVD. The findings add to the evidence that a telehealth and mHealth dual-modality HBCR program may be a promising approach to overcome some of the main barriers to improving CR access in the United States.

Coronary artery disease management in older adults: revascularization and exercise training

The mean age of patients with coronary artery disease (CAD) is steadily increasing. In older patients, there is a tendency to underutilize invasive approach, coronary revascularization, up-to-date pharmacological therapies, and secondary prevention strategies, including cardiac rehabilitation. Older adults with CAD commonly exhibit atypical symptoms, multi-vessel disease involvement, complex coronary anatomy, and a higher presence of risk factors and comorbidities. Although both invasive procedures and medical treatments are characterized by a higher risk of complications, avoidance may result in a suboptimal outcome. Often, overlooked factors, such as coronary microvascular disease, malnutrition, and poor physical performance, play a key role in determining prognosis, yet they are not routinely assessed or addressed in older patients. Historically, clinicians have relied on sub-analyses or observational findings to make clinical decisions, as older adults were frequently excluded or under-represented in clinical studies. Recently, dedicated evidence through randomized clinical trials has become available for older CAD patients. Nevertheless, the management of older CAD patients still raises several important questions. This review aims to comprehensively summarize and critically evaluate this emerging evidence, focusing on invasive management and coronary revascularization. Furthermore, it seeks to contextualize these interventions within the framework of improved risk stratification tools for older CAD patients, through user-friendly scales along with emphasizing the importance of promoting physical activity and exercise training to enhance the outcomes of invasive and medical treatments. This comprehensive approach may represent the key to improving prognosis in the complex and growing patient population of older CAD patients.

The Caring Life Course Theory: Opening new frontiers in care-A cardiac rehabilitation example

AIM(S)

To operationalize the Caring Life Course Theory (CLCT) as a framework for improving cardiac rehabilitation (CR) engagement and informing ways to address disparities in rural, low socio-economic areas.

METHODS

A secondary analysis of data collected from 15 CR programmes to identify CR patterns through the CLCT lens using a mixed-methods approach. All analytical processes were conducted in NVivo, coding qualitative data through thematic analysis based on CLCT constructs. Relationships among these constructs were quantitatively assessed using Jaccard coefficients and hierarchical clustering via dendrogram analysis to identify related clusters.

RESULTS

A strong interconnectedness among constructs: 'care from others', 'capability', 'care network' and 'care provision' (coefficient = 1) highlights their entangled crucial role in CR. However, significant conceptual disparities between 'care biography' and 'fundamental care' (coefficient = 0.4) and between 'self-care' and 'care biography' (coefficient = 0.384615) indicate a need for more aligned and personalized care approaches within CR.

CONCLUSION

The CLCT provides a comprehensive theoretical and practical framework to address disparities in CR, facilitating a personalized approach to enhance engagement in rural and underserved regions.

IMPLICATIONS

Integrating CLCT into CR programme designs could effectively address participation challenges, demonstrating the theory's utility in developing targeted, accessible care interventions/solutions.

IMPACT

Explored the challenge of low CR engagement in rural, low socio-economic settings. Uncovered care provision, transitions and individual care biographies' relevance for CR engagement. Demonstrated the potential of CLCT to inform/transform CR services for underserved populations, impacting practices and outcomes.

The iATTEND Trial: A Trial Comparing Hybrid Versus Standard Cardiac Rehabilitation

The improving ATTENDance (iATTEND) to cardiac rehabilitation (CR) trial tested the hypotheses that hybrid CR (HYCR) (combination of virtual and in-facility CR sessions) would result in greater attendance compared with traditional, facility-based only CR (FBCR) and yield equivalent improvements in exercise capacity and health status. Patients were randomized to HYCR (n = 142) or FBCR (n = 140), stratified by gender and race. Attendance was assessed as number of CR sessions completed within 6 months (primary end point) and the percentage of patients completing 36 CR sessions. Other end points (tested for equivalency) included exercise capacity and self-reported health status. HYCR patients completed 1 to 12 sessions in-facility, with the balance completed virtually using synchronized, 2-way audiovisual technology. Neither total number of CR sessions completed within 6 months (29 ± 12 vs 28 ± 12 visits, adjusted p = 0.94) nor percentage of patients completing 36 sessions (59 ± 4% vs 51 ± 4%, adjusted p = 0.32) were significantly different between HYCR and FBCR, respectively. The between-group changes for exercise capacity (peak oxygen uptake, 6-minute walk distance) and health status were equivalent. Regarding safety, no sessions required physician involvement, there was 1 major adverse event after a virtual session, and no falls required medical attention. In conclusion, although we rejected our primary hypothesis that attendance would be greater with HYCR versus FBCR, we showed that FBCR and HYCR resulted in similar patient attendance patterns and equivalent improvements in exercise capacity and health status. HYCR which incorporates virtually supervised exercise should be considered an acceptable alternative to FBCR.

Patterns of Referral and Postdischarge Utilization of Cardiac Rehabilitation Among Patients Hospitalized With Heart Failure: An Analysis From the GWTG-HF Registry

BACKGROUND

Coverage for cardiac rehabilitation (CR) for patients with heart failure with reduced ejection fraction was expanded in 2014, but contemporary referral and participation rates remain unknown.

METHODS

Patients hospitalized for heart failure with reduced ejection fraction (≤35%) in the American Heart Association Get With The Guidelines-Heart Failure registry from 2010 to 2020 were included, and CR referral status was described as yes, no, or not captured. Temporal trends in CR referral were assessed in the overall cohort. Patient and hospital-level predictors of CR referral were assessed using multivariable-adjusted logistic regression models. Additionally, CR referral and proportional utilization of CR within 1-year of referral were evaluated among patients aged >65 years with available Medicare administrative claims data who were clinically stable for 6-weeks postdischarge. Finally, the association of CR referral with the risk of 1-year death and readmission was evaluated using multivariable-adjusted Cox models.

RESULTS

Of 69,441 patients with heart failure with reduced ejection fraction who were eligible for CR (median age 67 years; 33% women; 30% Black), 17,076 (24.6%) were referred to CR, and referral rates increased from 8.1% in 2010 to 24.1% in 2020 (Ptrend<0.001). Of 8310 patients with Medicare who remained clinically stable 6-weeks after discharge, the CR referral rate was 25.8%, and utilization of CR among referred patients was 4.1% (mean sessions attended: 6.7). Patients not referred were more likely to be older, of Black race, and with a higher burden of comorbidities. In adjusted analysis, eligible patients with heart failure with reduced ejection fraction who were referred to CR (versus not referred) had a lower risk of 1-year death (hazard ratio, 0.84 [95% CI, 0.70-1.00]; P=0.049) without significant differences in 1-year readmission.

CONCLUSIONS

CR referral rates have increased from 2010 to 2020. However, only 1 in 4 patients are referred to CR. Among eligible patients who received CR referral, participation was low, with <1 of 20 participating in CR.

Stepped care versus center-based cardiopulmonary rehabilitation for older frail adults living in rural MA: Design of a feasibility randomized controlled trial

Background

Cardiac and pulmonary rehabilitation programs are grossly underutilized, and participation is particularly low in rural regions.

Methods

We are conducting a 2-arm, randomized controlled feasibility trial. Eligible participants include older frail adults with cardiac or pulmonary disease living in a predominantly rural county in western Massachusetts. Participants are randomized 1:1 to treatment as usual or stepped care. Patients randomized to treatment as usual participate in twice weekly center-based rehabilitation sessions over eight weeks and are encouraged to exercise at home in between sessions. Patients randomized to the stepped-care arm are offered/enrolled in the center-based rehabilitation program followed by possible step up to three interventions based on prespecified non-response criteria: 1) Transportation-assisted center-based rehabilitation, 2) Home-based telerehabilitation, and 3) Community health worker-supported home-based telerehabilitation. The primary feasibility outcomes are average number of eligible patients randomized per month, baseline measure completion, proportion attending at least 70% of the prescribed sessions, average number of sessions attended in the stepped-care arm, and proportion in the stepped-care arm completing patient reported outcome measures. Each of these process indicators is evaluated by preset "Stop" and "Go" thresholds.

Conclusion

The proposed stepped-care model is an efficient, patient-centered, approach to expanding access to cardiac and pulmonary rehabilitation. Meeting the "Go" thresholds for the prespecified process indicators will justify conducting a definitive full-scale randomized controlled trial to compare the effectiveness and value (cost-effectiveness) of stepped-care versus center-based rehabilitation in older frail adults living rural counties.

Cardiac rehabilitation for heart failure: 'Cinderella' or evidence-based pillar of care?

Cardiac rehabilitation remains the 'Cinderella' of treatments for heart failure. This state-of-the-art review provides a contemporary update on the evidence base, clinical guidance, and status of cardiac rehabilitation delivery for patients with heart failure. Given that cardiac rehabilitation participation results in important improvements in patient outcomes, including health-related quality of life, this review argues that an exercise-based rehabilitation is a key pillar of heart failure management alongside drug and medical device provision. To drive future improvements in access and uptake, health services should offer heart failure patients a choice of evidence-based modes of rehabilitation delivery, including home, supported by digital technology, alongside traditional centre-based programmes (or combinations of modes, 'hybrid') and according to stage of disease and patient preference.

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.

Geographical and Urban-Rural Disparities in Cardiac Rehabilitation Eligibility and Center-Based Use in the US

This cross-sectional study analyzes county-level eligibility, participation, adherence, and completion rates for cardiac rehabilitation services among Medicare beneficiaries.

Disparities in Geographic Access to Cardiac Rehabilitation in Los Angeles County

Background Exercise-based cardiac rehabilitation (CR) is known to reduce morbidity and mortality for patients with cardiac conditions. Sociodemographic disparities in accessing CR persist and could be related to the distance between where patients live and where CR facilities are located. Our objective is to determine the association between sociodemographic characteristics and geographic proximity to CR facilities. Methods and Results We identified actively operating CR facilities across Los Angeles County and used multivariable Poisson regression to examine the association between sociodemographic characteristics of residential proximity to the nearest CR facility. We also calculated the proportion of residents per area lacking geographic proximity to CR facilities across sociodemographic characteristics, from which we calculated prevalence ratios. We found that racial and ethnic minorities, compared with non-Hispanic White individuals, more frequently live ≥5 miles from a CR facility. The greatest geographic disparity was seen for non-Hispanic Black individuals, with a 2.73 (95% CI, 2.66-2.79) prevalence ratio of living at least 5 miles from a CR facility. Notably, the municipal region with the largest proportion of census tracts comprising mostly non-White residents (those identifying as Hispanic or a race other than White), with median annual household income <$60 000, contained no CR facilities despite ranking among the county's highest in population density. Conclusions Racial, ethnic, and socioeconomic characteristics are significantly associated with lack of geographic proximity to a CR facility. Interventions targeting geographic as well as nongeographic factors may be needed to reduce disparities in access to exercise-based CR programs. Such interventions could increase the potential of CR to benefit patients at high risk for developing adverse cardiovascular outcomes.

Disparities in the Use of Cardiac Rehabilitation in African Americans

Purpose of review

Cardiac rehabilitation (CR) is a comprehensive outpatient program that reduces the risk of mortality and recurrent events and improves functional status and quality of life for patients recovering from acute cardiovascular disease (CVD) events. Among individuals with established CVD, African Americans have a higher risk of major cardiac events, which underscores the importance of CR use among African Americans. However, despite their high likelihood of adverse outcomes, CR is poorly utilized in African Americans with CVD. We review data on CR utilization among African Americans, barriers to participation, and the implications for policy and practice.

Recent findings

Although established as a highly effective secondary prevention strategy, CR is underutilized in general, but especially by African Americans. Notwithstanding efforts to increase CR participation among all groups, participation rates remain low for African Americans and other minorities compared to Non-Hispanic Whites. The low CR participation rates by African Americans can be attributed to an array of factors including differential referral patterns, access to care, and socioeconomic factors. There are several promising strategies to improve CR participation which include promoting evidence-based guidelines, reducing barriers to access, novel CR delivery modalities, including more African Americans in CR clinical research, and increasing diversity in the CR workforce.

Summary

African Americans with CVD events are less likely to be referred to, enroll in, and complete CR than Non-Hispanic Whites. There are many factors that impact CR participation by African Americans. Initiatives at the health policy, health system, individual, and community level will be needed to reduce these disparities in CR use.

Implementation of an Appointment-Based Cardiac Rehabilitation Approach: A Single-Center Experience

Background There has been a focus on alternative cardiac rehabilitation (CR) delivery models aimed at improving CR adherence and completion. We examined pre- and post-CR health outcomes, reasons for discharge, and predictors of completion using a patient-driven appointment-based CR approach that uses center-scheduled class start times. Methods and Results Data were used from an urban single-center CR program at Yale New Haven Health (2012-2017) that enrolled 2135 patients. We evaluated pre- and post-CR outcomes (12 weeks) using paired t tests and used a multivariable logistic regression model to examine predictors of CR completion (≥36 sessions) for the overall cardiovascular disease population. The mean age of participants was 65±12 years, 27.9% were women, and 5.1% were Black patients, and patients completed a median of 30 of 36 sessions. Patients achieved significant improvements in health outcomes, including across age and sex subgroups. The primary reason for discharge was completion of all 36 sessions of CR (46.4%). The final logistic regression model contained 12 predictors: age, sex, Black race, marital status, employment, number of physician-reported risk factors, dietary fat intake >30%, obesity, lack of exercise, benign prostatic hyperplasia, and self-reported stress and physical activity. Conclusions We demonstrated that patients participating in an appointment-based CR program achieved significant improvements in health outcomes and across sex/age subgroups. In addition, older individuals were more likely to complete CR. An appointment-based approach could be a viable alternative CR method to aid in optimizing the dose-response benefit of CR for patients with cardiovascular disease.

A Structured Review of Commercially Available Cardiac Rehabilitation mHealth Applications Using the Mobile Application Rating Scale

PURPOSE

This study systematically evaluated the quality and functionalities of patient-facing, commercially available mobile health (mHealth) apps for cardiac rehabilitation (CR).

METHODS

We performed our search in two of the most widely used commercial mobile app stores: Apple iTunes Appstore and Google Play Store (Android apps). Six search terms were used to query relevant CR apps: "cardiac rehabilitation," "heart disease and remote therapy," "heart failure exercise," "heart therapy and cardiac recovery," "cardiac recovery," and "heart therapy." App quality was evaluated using the Mobile Application Rating Scale (MARS). App functionality was evaluated using the IQVIA functionality scale, and app content was evaluated against the American Heart Association guidelines for CR. Apps meeting our inclusion criteria were downloaded and evaluated by two to three reviewers, and interclass correlations between reviewers were calculated.

RESULTS

We reviewed 3121 apps and nine apps met our inclusion criteria. On average, the apps scored a 3.0 on the MARS (5-point Likert scale) for overall quality. The two top-ranking mHealth apps for CR for all three quality, functionality, and consistency with evidence-based guidelines were My Cardiac Coach and Love My Heart for Women, both of which scored ≥4.0 for behavior change.

CONCLUSION

Overall, the quality and functionality of free apps for mobile CR was high, with two apps performing the best across all three quality categories. High-quality CR apps are available that can expand access to CR for patients with cardiovascular disease.

Understanding the importance of social determinants and rurality for the long-term outcome after acute myocardial infarction: study protocol for a single-centre cohort study

INTRODUCTION

Acute myocardial infarction (AMI) is a major public health issue in Germany with considerable regional differences in morbidity and mortality. Possible reasons for regional differences include a higher prevalence of cardiovascular risk factors, infrastructural deficits, different levels of healthcare quality or social determinants. We aim to study associations of social determinants and of rural infrastructure with the quality of medical care (eg, time to reperfusion or medication adherence) and on the long-term outcome after myocardial infarction.

METHODS AND ANALYSIS

We will employ a prospective cohort study design. Patients who are admitted with AMI will be invited to participate. We aim to recruit a total of 1000 participants over the course of 5 years. Information on outpatient care prior to AMI, acute healthcare of AMI, healthcare-related environmental factors and social determinants will be collected. Baseline data will be assessed in interviews and from the electronic data system of the hospital. Follow-up will be conducted after an observation period of 1 year via patient interviews. The outcomes of interest are cardiac and all-cause mortality, changes in quality of life, changes in health status of heart failure, major adverse cardiovascular events and participation in rehabilitation programmes.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Ethics Committee of Brandenburg Medical School (reference: E-01-20200923). Research findings will be disseminated and shared in different ways and include presenting at international and national conferences, publishing in peer-reviewed journals and facilitating dissemination workshops within local communities with patients and healthcare professionals.

Rural-Urban Disparities in Outcomes of Myocardial Infarction, Heart Failure, and Stroke in the United States

BACKGROUND

U.S. policy efforts have focused on reducing rural-urban health inequities. However, it is unclear whether gaps in care and outcomes remain among older adults with acute cardiovascular conditions.

OBJECTIVES

This study aims to evaluate rural-urban differences in procedural care and mortality for acute myocardial infarction (AMI), heart failure (HF), and ischemic stroke.

METHODS

This is a retrospective cross-sectional study of Medicare fee-for-service beneficiaries aged ≥65 years with acute cardiovascular conditions from 2016 to 2018. Cox proportional hazards models with random hospital intercepts were fit to examine the association of presenting to a rural (vs urban) hospital and 30- and 90-day patient-level mortality.

RESULTS

There were 2,182,903 Medicare patients hospitalized with AMI, HF, or ischemic stroke from 2016 to 2018. Patients with AMI were less likely to undergo cardiac catherization (49.7% vs 63.6%, P < 0.001), percutaneous coronary intervention (42.1% vs 45.7%, P < 0.001) or coronary artery bypass graft (9.0% vs 10.2%, P < 0.001) within 30 days at rural versus urban hospitals. Thrombolysis rates (3.1% vs 10.1%, P < 0.001) and endovascular therapy (1.8% vs 3.6%, P < 0.001) for ischemic stroke were lower at rural hospitals. After adjustment for demographics and clinical comorbidities, the 30-day mortality HR was significantly higher among patients presenting to rural hospitals for AMI (HR: 1.10, 95% CI: 1.08 to 1.12), HF (HR: 1.15; 95% CI: 1.13 to 1.16), and ischemic stroke (HR: 1.20; 95% CI: 1.18 to 1.22), with similar patterns at 90 days. These differences were most pronounced for the subset of critical access hospitals that serve remote, rural areas.

CONCLUSIONS

Clinical, public health, and policy efforts are needed to improve rural-urban gaps in care and outcomes for acute cardiovascular conditions.

Enrollment and Adherence to Early Outpatient and Maintenance Cardiac Rehabilitation Programs

Early outpatient (ECR) and maintenance cardiac rehabilitation (MCR) programs are essential, evidence-based services that have received unequivocal endorsement by national and international professional organizations. However, the latest data characterizing ECR enrollment and adherence fell well short of what would be expected for a therapy that has accumulated decades of empirical evidence touting the associated physiologic, physical, psychosocial, and financial benefits. Although national participation levels have remained stagnant, a series of recent publications showcase effective strategies that could bolster both ECR enrollment and adherence levels at the institutional level. Unlike ECR, fewer reports on enrollment and adherence rates exist for MCR, partly due to the lack of standardization of this service. In this review, we aim to highlight current data on enrollment and adherence to ECR and MCR and discuss evidence-based programmatic strategies to support utilization of both services.

A Review of Disparities in Cardiac Rehabilitation: EVIDENCE, DRIVERS, AND SOLUTIONS

PURPOSE

Cardiac rehabilitation (CR) has been shown to improve functional status, quality of life, and recurrent cardiovascular disease (CVD) events. Despite its demonstrated compelling benefits and guideline recommendation, CR is underutilized, and there are significant disparities in CR utilization particularly by race, ethnicity, sex, and socioeconomic status. The purpose of this review is to summarize the evidence and drivers of these disparities and recommend potential solutions.

METHODS

In this review, key studies documenting disparities in CR referrals, enrollment, and completion are discussed. Additionally, potential mechanisms for these disparities are summarized and strategies are reviewed for addressing them.

SUMMARY

There is a wealth of literature demonstrating disparities among racial and ethnic minorities, women, those with lower income and education attainment, and those living in rural and dense urban areas. However, there was minimal focus on how the social determinants of health contribute to the observed disparities in CR utilization in many of the studies reviewed. Interventions such as automatic referrals, inpatient liaisons, mitigation of economic barriers, novel delivery mechanisms, community partnerships, and health equity metrics to incentivize health care organizations to reduce care disparities are potential solutions.

Million Hearts Cardiac Rehabilitation Think Tank: Accelerating New Care Models

This article describes the October 2020 proceedings of the Million Hearts Cardiac Rehabilitation Think Tank: Accelerating New Care Models, convened with representatives from professional organizations, cardiac rehabilitation (CR) programs, academic institutions, federal agencies, payers, and patient representative groups. As CR delivery evolves, terminology is evolving to reflect not where activities occur (eg, center, home) but how CR is delivered: in-person synchronous, synchronous with real-time audiovisual communication (virtual), or asynchronous (remote). Patients and CR staff may interact through ≥1 delivery modes. Though new models may change how CR is delivered and who can access CR, new models should not change what is delivered-a multidisciplinary program addressing CR core components. During the coronavirus disease 2019 (COVID-19) public health emergency, Medicare issued waivers to allow virtual CR; it is unclear whether these waivers will become permanent policy post-public health emergency. Given CR underuse and disparities in delivery, new models must equitably address patient and health system contributors to disparities. Strategies for implementing new CR care models address safety, exercise prescription, monitoring, and education. The available evidence supports the efficacy and safety of new CR care models. Still, additional research should study diverse populations, impact on patient-centered outcomes, effect on long-term outcomes and health care utilization, and implementation in diverse settings. CR is evolving to include in-person synchronous, virtual, and remote modes of delivery; there is significant enthusiasm for implementing new care models and learning how new care models can broaden access to CR, improve patient outcomes, and address health inequities.

Barriers to Cardiac Rehabilitation in Ethnic Minority Groups: A Scoping Review

Cardiac rehabilitation (CR) is under-utilized by ethnic minorities. This study aimed to identify barriers associated with referral, enrollment, and completion/adherence of CR for cardiac participants from ethnic minorities. Medline, Embase, Emcare, CINAHL, Pubmed and APA PsycInfo were searched from data inception through January 2020. We excluded studies referring to race minorities, considering barriers reported by providers or family members, and those published in languages other than English or Portuguese. Data was extracted in an individual, provider, and system level. Of 1847 initial citations, 20 studies were included, with most being qualitative in design and classified as "good" quality. Overall, 12 multi-level barriers were identified in the three CR participation phases, with language being present in all phases. Barriers reported in ethnic minority groups are multi-level. Although identified, literature did not support recommendations to overcome these barriers and clearly more research in this area is needed.

Early Increased Physical Activity, Cardiac Rehabilitation, and Survival After Implantable Cardioverter-Defibrillator Implantation

BACKGROUND

Increased physical activity (PA) through cardiac rehabilitation (CR) improves outcomes in patients with heart failure and coronary disease, but CR referral remains infrequent. Implantable cardioverter-defibrillators (ICDs) can provide daily PA measurements to patients that may motivate them to increase PA, but it remains unclear if increased ICD measured PA is associated with improved outcomes with and without CR.

METHODS

This is a retrospective observational study of 41 731 Medicare beneficiaries with ICD implantation between January 1, 2014 and December 31, 2016. We linked daily ICD PA measurements and Medicare claims data to determine if increased PA is associated with a reduction in the likelihood of death or heart failure hospitalization. To determine if CR participation altered the effect of PA on outcomes, we performed two additional analyses matching CR participants and nonparticipants using propensity scores. The first match included demographics, comorbidities, and baseline PA measurements. The second match also included the change in PA measured during CR or the same time frame after ICD implant among nonparticipants.

RESULTS

The mean age was 75 (SD, 10) years, 30 182 beneficiaries (72.3%) were male, and 1324 (3%) participated in CR. Increased ICD detected PA was associated with improved survival. CR participants had a mean PA change of +9.7 (SD, 57.8) min/d, whereas nonparticipants had a mean change of -1.0 (SD, 59.7) min/d (P<0.001). After matching for demographics, comorbidities and baseline PA, CR participants had significantly lower 1- to 3-year mortality (hazard ratio, 0.76 [95% CI, 0.69-0.85], P=0.03). After additionally matching for the ICD measured change in PA during CR there were no differences in mortality with and without CR (hazard ratio, 1.00 [95% CI, 0.82-1.21], P=0.87). Every 10 minutes of increased daily PA was associated with a 1.1% reduction in all-cause mortality in both groups.

CONCLUSIONS

Among Medicare beneficiaries with ICDs, small increases in PA were associated with significant reductions in all-cause mortality.

Temporal Trends and Factors Associated With Cardiac Rehabilitation Participation Among Medicare Beneficiaries With Heart Failure

OBJECTIVES

The purpose of this study was to assess temporal trends and factors associated with cardiac rehabilitation (CR) enrollment and participation among Medicare beneficiaries after the 2014 Medicare coverage expansion.

BACKGROUND

CR improves exercise capacity, quality of life, and clinical outcomes in heart failure (HF) with reduced ejection fraction (HFrEF). In 2014, Medicare coverage for CR was expanded to include chronic HFrEF.

METHODS

Among Medicare beneficiaries from quarter (Q) 1 2014 to Q2 2016, 11,696 patients from 14,258 hospitalizations with primary discharge diagnosis of HF were identified. Patients with HF with preserved ejection fraction were excluded. Quarterly CR participation rates among hospitalized HF patients within 6 months of discharge were identified through outpatient administrative claims. The predictors of CR participation were assessed with the use of a multivariable logistic regression model that included patient- and hospital-level characteristics. A secondary analysis to assess participation rates of CR after outpatient encounters for HF was performed.

RESULTS

Overall, only 611 (4.3%) and 349 (2.2%) eligible patients participated CR after primary hospitalization or outpatient visit for HF, respectively. There was a modest, statistically significant increase in CR participation after HF admissions (2.8% in Q1 2014; 5.0% in Q2 2016; p < 0.001) without significant increase after outpatient visits for HF (2.6% to 3.8%; p = 0.21). Younger age, male sex, nonblack race, previous cardiovascular procedures, and hospitalization at hospitals with available CR facilities were all independently associated with CR participation.

CONCLUSIONS

CR participation among eligible Medicare beneficiaries with HFrEF was low with minimal increase since 2014 Medicare coverage decision. Sex, race, and institution-dependent variables were independent predictors of CR participation.

Cardiac Rehabilitation for Patients With Heart Failure: JACC Expert Panel

Cardiac rehabilitation is defined as a multidisciplinary program that includes exercise training, cardiac risk factor modification, psychosocial assessment, and outcomes assessment. Exercise training and other components of cardiac rehabilitation (CR) are safe and beneficial and result in significant improvements in quality of life, functional capacity, exercise performance, and heart failure (HF)-related hospitalizations in patients with HF. Despite outcome benefits, cost-effectiveness, and strong practice guideline recommendations, CR remains underused. Clinicians, health care leaders, and payers should prioritize incorporating CR as part of the standard of care for patients with HF.

Impact of patient characteristics and perceived barriers on referral to exercise rehabilitation among patients with pulmonary hypertension in the United States

Exercise rehabilitation is underutilized in patients with pulmonary arterial hypertension despite improving exercise capacity and quality of life. We sought to understand the association between (1) patient characteristics and (2) patient-perceived barriers and referral to exercise rehabilitation. We performed a cross-sectional survey of patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension attending an International PAH meeting. Predictors of referral considered included gender, body mass index, subjective socioeconomic status, insurance type, age, and World Health Organization functional class and perceived barriers assessed using the Cardiac Rehabilitation Barriers Scale. Among 65 participants, those in the lowest subjective socioeconomic status tertile had reduced odds of referral compared to the highest tertile participants (odds ratio 0.22, 95% confidence interval: 0.05–0.98, p = 0.047). Several patient-perceived barriers were associated with reduced odds of referral. For every 1-unit increase in a reported barrier on a five-point Likert scale, odds of referral were reduced by 85% for my doctor did not feel it was necessary; 85% for prefer to take care of my health alone, not in a group; 78% many people with heart and lung problems don’t go, and they are fine; and 78% for I didn’t know about exercise therapy. The lack of perceived need subscale and overall barriers score were associated with a 92% and 77% reduced odds of referral, respectively. These data suggest the need to explore interventions to promote referral among low socioeconomic status patients and address perceived need for the therapy.

Disparities in Health Care for Black Patients in Physical Medicine and Rehabilitation in the United States: A Narrative Review

Racial health disparities continue to disproportionately affect Black persons in the United States. Black individuals also have increased risk of worse outcomes associated with social determinants of health including socioeconomic factors such as income, education, and employment. This narrative review included studies originally spanning a period of approximately one decade (December 2009-December 2019) from online databases and with subsequent updates though June 2020. The findings to date suggest pervasive inequities across common conditions and injuries in physical medicine and rehabilitation for this group compared to other racial/ethnic groups. We found health disparities across several domains for Black persons with stroke, traumatic brain injury, spinal cord injury, hip/knee osteoarthritis, and fractures, as well as cardiovascular and pulmonary disease. Although more research is needed, some contributing factors include low access to rehabilitation care, fewer referrals, lower utilization rates, perceived bias, and more self-reliance, even after adjusting for hospital characteristics, age, disease severity, and relevant socioeconomic variables. Some studies found that Black individuals were less likely to receive care that was concordant with clinical guidelines per the reported literature. Our review highlights many gaps in the literature on racial disparities that are particularly notable in cardiac, pulmonary, and critical care rehabilitation. Clinicians, researchers, and policy makers should therefore consider race and ethnicity as important factors as we strive to optimize rehabilitation care for an increasingly diverse U.S. population.

Effectiveness of an Education Intervention Among Cardiac Rehabilitation Patients in Canada: A Multi-Site Study

BACKGROUND

Although patient education is considered a core component of cardiac rehabilitation (CR) programs, to our knowledge, no educational program designed for CR has been standardized in Canada. This absence of standardization may be due to a lack of reliable resources to educate these patients. The objective of this study was to assess the effectiveness of an education intervention in improving knowledge and health behaviours among CR patients in 3 sites in Canada.

METHODS

CR patients were exposed to an evidence- and theoretically based comprehensive education intervention. Patients completed surveys assessing knowledge, physical activity, food intake, self-efficacy, and health literacy. All outcomes were assessed pre- and post-CR. Paired t tests were used to investigate variable changes between pre- and post-CR, Pearson correlation coefficients were used to determine the association between knowledge and behaviours, and linear regression models were computed to investigate differences in overall post-CR knowledge based on participant characteristics.

RESULTS

A total of 252 patients consented to participate, of whom 158 (63.0%) completed post-CR assessments. There was a significant improvement in patients' overall knowledge pre- to post-CR, as well as in exercise, food intake, and self-efficacy (P < 0.05). Results showed a significant positive correlation between post-CR knowledge and food intake (r = 0.203; P = 0.01), self-efficacy (r = 0.201; P = 0.01), and health literacy (r = 0.241; P = 0.002). Education level (unstandardized beta = -2.511; P = 0.04) and pre-CR knowledge (unstandardized beta = 0.433; P < 0.001) were influential in changing post-CR knowledge.

CONCLUSION

In this first-ever multi-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention have been supported.

Addressing Social Determinants of Health in the Care of Patients With Heart Failure: A Scientific Statement From the American Heart Association

Heart failure is a clinical syndrome that affects >6.5 million Americans, with an estimated 550 000 new cases diagnosed each year. The complexity of heart failure management is compounded by the number of patients who experience adverse downstream effects of the social determinants of health (SDOH). These patients are less able to access care and more likely to experience poor heart failure outcomes over time. Many patients face additional challenges associated with the cost of complex, chronic illness management and must make difficult decisions about their own health, particularly when the costs of medications and healthcare appointments are at odds with basic food and housing needs. This scientific statement summarizes the SDOH and the current state of knowledge important to understanding their impact on patients with heart failure. Specifically, this document includes a definition of SDOH, provider competencies, and SDOH assessment tools and addresses the following questions: (1) What models or frameworks guide healthcare providers to address SDOH? (2) What are the SDOH affecting the delivery of care and the interventions addressing them that affect the care and outcomes of patients with heart failure? (3) What are the opportunities for healthcare providers to address the SDOH affecting the care of patients with heart failure? We also include a case study ( Data Supplement ) that highlights an interprofessional team effort to address and mitigate the effects of SDOH in an underserved patient with heart failure.

Call to Action: Rural Health: A Presidential Advisory From the American Heart Association and American Stroke Association

Understanding and addressing the unique health needs of people residing in rural America is critical to the American Heart Association's pursuit of a world with longer, healthier lives. Improving the health of rural populations is consistent with the American Heart Association's commitment to health equity and its focus on social determinants of health to reduce and ideally to eliminate health disparities. This presidential advisory serves as a call to action for the American Heart Association and other stakeholders to make rural populations a priority in programming, research, and policy. This advisory first summarizes existing data on rural populations, communities, and health outcomes; explores 3 major groups of factors underlying urban-rural disparities in health outcomes, including individual factors, social determinants of health, and health delivery system factors; and then proposes a set of solutions spanning health system innovation, policy, and research aimed at improving rural health.

Tracking Cardiac Rehabilitation Participation and Completion Among Medicare Beneficiaries to Inform the Efforts of a National Initiative

BACKGROUND

Despite cardiac rehabilitation (CR) being shown to improve health outcomes among patients with heart disease, its use has been suboptimal. In response, the Million Hearts Cardiac Rehabilitation Collaborative developed a road map to improve CR use, including increasing participation rates to ≥70% by 2022. This observational study provides current estimates to measure progress and identifies the populations and regions most at risk for CR service underutilization.

METHODS AND RESULTS

We identified Medicare fee-for-service beneficiaries who were CR eligible in 2016, and assessed CR participation (≥1 CR session attended), timely initiation (participation within 21 days of event), and completion (≥36 sessions attended) through 2017. Measures were assessed overall, by beneficiary characteristics and geography, and by primary CR-qualifying event type (acute myocardial infarction hospitalization; coronary artery bypass surgery; heart valve repair/replacement; percutaneous coronary intervention; or heart/heart-lung transplant). Among 366 103 CR-eligible beneficiaries, 89 327 (24.4%) participated in CR, of whom 24.3% initiated within 21 days and 26.9% completed CR. Eligibility was highest in the East South Central Census Division (14.8 per 1000). Participation decreased with increasing age, was lower among women (18.9%) compared with men (28.6%; adjusted prevalence ratio: 0.91 [95% CI, 0.90-0.93]) was lower among Hispanics (13.2%) and non-Hispanic blacks (13.6%) compared with non-Hispanic whites (25.8%; adjusted prevalence ratio: 0.63 [0.61-0.66] and 0.70 [0.67-0.72], respectively), and varied by hospital referral region and Census Division (range: 18.6% [East South Central] to 39.1% [West North Central]) and by qualifying event type (range: 7.1% [acute myocardial infarction without procedure] to 55.3% [coronary artery bypass surgery only]). Timely initiation varied by geography and qualifying event type; completion varied by geography.

CONCLUSIONS

Only 1 in 4 CR-eligible Medicare beneficiaries participated in CR and marked disparities were observed. Reinforcement of current effective strategies and development of new strategies will be critical to address the noted disparities and achieve the 70% participation goal.

Systematic review of cardiac rehabilitation guidelines: Quality and scope

Cardiac rehabilitation is a comprehensive model of secondary prevention proven to reduce mortality and morbidity. The World Health Organization is developing a Package of Rehabilitation Interventions for implementation by ministries of health as part of universal healthcare across the continuum. Through a systematic review, we sought to identify the best-quality cardiac rehabilitation guidelines, and extract their recommendations for implementation by member states. A systematic search was undertaken of academic databases and guideline repositories, among other sources, through to April 2019, for English-language cardiac rehabilitation guidelines from the last 10 years, free from conflicts, and with strength of recommendations. Two authors independently considered all citations. Potentially eligible guidelines were rated for quality using the Appraisal of Guidelines for Research and Evaluation tool, and for other characteristics such as being multi-professional, comprehensive and international in perspective; the latter criteria were used to inform selection of 3-5 guidelines meeting inclusion criteria. Equity considerations were also extracted. Altogether, 2076 unique citations were identified. Thirteen passed title and abstract screening, with six guidelines potentially eligible for inclusion in the Package of Rehabilitation Interventions and rated for quality; for two guidelines the Appraisal of Guidelines for Research and Evaluation tool ratings did not meet World Health Organization minimums. Of the four eligible guidelines, three were selected: the International Council of Cardiovascular Prevention and Rehabilitation (2016), National Institute for Health and Care Excellence (#172; 2013) and Scottish Intercollegiate Guideline Network (#150; 2017). Extracted recommendations were comprehensive, but psychosocial recommendations were contradictory and diet recommendations were inconsistent. A development group of the World Health Organization will review and refine the recommendations which will then undergo peer review, before open source dissemination for implementation.

Effect of text messaging on depression in patients with coronary heart disease: a substudy analysis from the TEXT ME randomised controlled trial

OBJECTIVE

We aimed to evaluate the effects on depression scores of a lifestyle-focused cardiac support programme delivered via mobile phone text messaging among patients with coronary heart disease (CHD).

DESIGN

Substudy and secondary analysis of a parallel-group, single-blind randomised controlled trial of patients with CHD.

SETTING

A tertiary hospital in Sydney, Australia.

INTERVENTION

The Tobacco, Exercise and dieT MEssages programme comprised four text messages per week for 6 months that provided education, motivation and support on diet, physical activity, general cardiac education and smoking, if relevant. The programme did not have any specific mental health component.

OUTCOMES

Depression scores at 6 months measured using the Patient Health Questionnaire-9 (PHQ-9). Treatment effect across subgroups was measured using log-binomial regression model for the binary outcome (depressed/not depressed, where depressed is any score of PHQ-9 ≥5) with treatment, subgroup and treatment by subgroup interaction as fixed effects.

RESULTS

Depression scores at 6 months were lower in the intervention group compared with the control group, mean difference 1.9 (95% CI 1.5 to 2.4, p<0.0001). The frequency of mild or greater depressive symptoms (PHQ-9 scores≥5) at 6 months was 21/333 (6.3%) in the intervention group and 86/350 (24.6%) in the control group (relative risk (RR) 0.26, 95% CI 0.16 to 0.40, p<0.001). This proportional reduction in depressive symptoms was similar across groups defined by age, sex, education, body mass index, physical activity, current smoking, current drinking and history of depression, diabetes and hypertension. In particular, the rates of PHQ-9 ≥5 among people with a history of depression were 4/44 (9.1%) vs 29/62 (46.8%) in intervention vs control (RR 0.19, 95% CI 0.07 to 0.51, p<0.001), and were 17/289 (5.9%) vs 57/288 (19.8%) among others (RR 0.30, 95% CI 0.18 to 0.50, p<0.001).

CONCLUSIONS

Among people with CHD, a cardiac support programme delivered via mobile phone text messaging was associated with fewer symptoms of mild-to-moderate depression at 6 months in the treatment group compared with controls.

Mobile Technology Utilization Among Patients From Diverse Cultural and Linguistic Backgrounds Attending Cardiac Rehabilitation in Australia: Descriptive, Case-Matched Comparative Study

Background

Barriers to attending cardiac rehabilitation (CR), including cultural and linguistic differences, may be addressed by recent technological developments. However, the feasibility of using these approaches in culturally and linguistically diverse patients is yet to be determined.

Objective

This study aims to assess the use of mobile technologies and features, as well as confidence in utilization across patients speaking different languages at home (ie, English, Mandarin Chinese, and a language other than English and Mandarin [other]) and are both eligible and physically suitable for CR. In addition, the study aims to determine the sociodemographic correlates of the mobile technology/feature use, including language spoken at home in the three groups mentioned above.

Methods

This is a descriptive, case matched, comparative study. Age and gender-matched patients speaking English, Mandarin and other languages (n=30/group) eligible for CR were surveyed for their mobile technology and mobile feature use.

Results

‘Participants had a mean age of 66.7 years (SD 13, n=90, range 46-95), with 53.3% (48/90) male. The majority (82/90, 91.1%) used at least one technology device, with 87.8% (79/90) using mobile devices, the most common being smartphones (57/90, 63.3%), tablets (28/90, 31.1%), and text/voice-only phones (24/90, 26.7%). More English-speaking participants used computers than Mandarin or “other” language speaking participants (P=.003 and .02) and were more confident in doing so compared to Mandarin-speaking participants (P=.003). More Mandarin-speaking participants used smartphones compared with “other” language speaking participants (P=.03). Most commonly used mobile features were voice calls (77/82, 93.9%), text message (54/82, 65.9%), the internet (39/82, 47.6%), email (36/82, 43.9%), and videoconferencing (Skype or FaceTime [WeChat or QQ] 35/82, 42.7%). Less Mandarin-speaking participants used emails (P=.001) and social media (P=.007) than English-speaking participants. Speaking Mandarin was independently associated with using smartphone, emails, and accessing the web-based medication information (OR 7.238, 95% CI 1.262-41.522; P=.03, OR 0.089, 95% CI 0.016-0.490; P=.006 and OR 0.191, 95% CI 0.037-0.984; P=.05).

Conclusions

This study reveals a high usage of mobile technology among CR patients and provides further insights into differences in the technology use across CALD patients in Australia. The findings of this study may inform the design and implementation of future technology-based CR.

Health Care Use and Associated Time and Out of Pocket Expenditures for Patients With Cardiovascular Disease in a Publicly Funded Health Care System

BACKGROUND

The objectives of this study were to describe (1) health care use and associated patient time and out of pocket (OOP) costs over 2 years after a cardiac diagnosis, (2) the sociodemographic and clinical drivers of these costs, and (3) patient costs related to cardiac rehabilitation (CR) participation.

METHODS

Secondary analysis was conducted in an observational prospective CR program evaluation cohort in Ontario, which has a publicly funded health care system. A convenience sample of patients from 1 of 3 CR programs was approached at the first visit, and consenting participants completed a survey. Participants were e-mailed surveys again 6 months and 1 and 2 years later; these later surveys assessed their cardiac care and medications and the time and OOP costs associated with care visits. Patient time was valued based on average wages in Ontario.

RESULTS

Of 411 consenting patients, 240 (58.3%) completed CR, and 192 (46.7%) were retained at 2 years. Patients most often visited a general practitioner and had electrocardiography and treatment for angina. The total cost to patients over 2 years was CAD$73.70 ± $275.84 for time and $377.01 ± $321.72 for OOP costs ($525.93 ± $467.08 overall). With adjustment, there were significantly higher OOP costs for women (P < 0.001) and less educated (P < 0.001) patients. Participants spent considerable money that was relatively OOP on CR visits alone ($384.78 ± $269.67), with time costs at $379.07 ± $1035.49 ($939.43 ± $1333.29 overall; 1.6% share of 1 year's income).

CONCLUSIONS

In conclusion, time and OOP costs are modest for patients with cardiac conditions, except for CR. Alternative delivery models are needed, in particular for low-income patients.

Disparities in Cardiac Rehabilitation Participation in the United States: A SYSTEMATIC REVIEW AND META-ANALYSIS

PURPOSE

Phase 2 cardiac rehabilitation (CR) is a class I recommendation for all patients following an acute cardiac event or cardiac surgery according to the The American Heart Association and the American College of Cardiology Foundation. Studies have shown that there are differences in cardiac rehabilitation participation rates between sociodemographic groups. The purpose of this systematic review and meta-analyses was to synthesize quantitative data on the relationship between outpatient cardiac rehabilitation (OCR) attendance and various sociodemographic factors.

METHODS

We conducted a search of PubMed, PsycINFO, CINAHL, Google Scholar, Dissertations & Theses A&I, and conference abstracts for observational studies conducted in the United States that fit our inclusion criteria. A total of 21 studies were included in our final review and meta-analyses.

RESULTS

Our meta-analyses showed that overall, attenders were younger than nonattenders (mean difference=-3.74 years, 95% CI =-5.87 to -1.61) and the odds of participation were lower among females (OR = 0.59; 95% CI = 0.51-0.69), individuals with a high school degree or less (OR = 0.67; 95% CI = 0.50-0.91), and the uninsured or self-payers (OR = 0.32; 95% CI = 0.14-0.71). Full- or part-time employees were more likely to participate than those not employed (OR = 1.45; 95% CI = 1.08-1.95).

CONCLUSIONS

Our systematic review and meta-analyses showed that there are significant sociodemographic disparities in CR participation. On the basis of this knowledge, clinicians and policy makers should focus on identifying and eliminating barriers to participation.

Association of Neighborhood Socioeconomic Context With Participation in Cardiac Rehabilitation

BACKGROUND

Cardiac rehabilitation (CR) is underutilized in the United States, with fewer than 20% of eligible patients participating in CR programs. Individual socioeconomic status is associated with CR utilization, but data regarding neighborhood characteristics and CR are sparse. We investigated the association of neighborhood socioeconomic context with CR participation in the SCCS (Southern Community Cohort Study).

METHODS AND RESULTS

The SCCS is a prospective cohort study of 84 569 adults in the southeastern United States from 2002 to 2009, 52 117 of whom have Medicare or Medicaid claims. Using these data, we identified participants with hospitalizations for myocardial infarction, percutaneous coronary intervention, or coronary artery bypass surgery and ascertained their CR utilization. Neighborhood socioeconomic context was assessed using a neighborhood deprivation index derived from 11 census-tract level variables. We analyzed the association of CR utilization with neighborhood deprivation after adjusting for individual socioeconomic status. A total of 4096 SCCS participants (55% female, 57% black) with claims data were eligible for CR. CR utilization was low, with 340 subjects (8%) participating in CR programs. Study participants residing in the most deprived communities (highest quintile of neighborhood deprivation) were less than half as likely to initiate CR (odds ratio 0.42, 95% confidence interval, 0.27-0.66, P<0.001) as those in the lowest quintile. CR participation was inversely associated with all-cause mortality (hazard ratio 0.77, 95% confidence interval, 0.60-0.996, P<0.05).

CONCLUSIONS

Lower neighborhood socioeconomic context was associated with decreased CR participation independent of individual socioeconomic status. These data invite research on interventions to increase CR access in deprived communities.

Effect of Socioeconomic Status on Propensity to Change Risk Behaviors Following Myocardial Infarction: Implications for Healthy Lifestyle Medicine

Failure to change risk behaviors following myocardial infarction (MI) increases the likelihood of recurrent MI and death. Lower-socioeconomic status (SES) patients are more likely to engage in high-risk behaviors prior to MI. Less well known is whether propensity to change risk behaviors after MI also varies inversely with SES. We performed a systematized literature review addressing changes in risk behaviors following MI as a function of SES. 2160 abstracts were reviewed and 44 met eligibility criteria. Behaviors included smoking cessation, cardiac rehabilitation (CR), medication adherence, diet, and physical activity (PA). For each behavior, lower-SES patients were less likely to change after MI. Overall, lower-SES patients were 2 to 4 times less likely to make needed behavior changes (OR's 0.25-0.56). Lower-SES populations are less successful at changing risk behaviors post-MI. Increasing their participation in CR/secondary prevention programs, which address multiple risk behaviors, including increasing PA and exercise, should be a priority of healthy lifestyle medicine (HLM).

Patient-perceived acceptability of a virtual world-based cardiac rehabilitation program

Background

Despite its benefits, cardiac rehabilitation (CR) participation rates remain subpar. Telehealth lifestyle interventions have emerged as modalities to enhance CR accessibility. Virtual-world (VW) technology may provide a means to increase CR use.

Objectives

This pilot study assessed the feasibility and acceptability of a VW-based CR program as an extension to medical center-based CR. Our goal is to apply the study results toward the design of a patient-centered VW platform prototype with high usability, understandability, and credibility.

Methods

Patients (n = 8, 25% women) recently enrolled in outpatient CR at Mayo Clinic, Rochester, Minnesota participated in a 12-week, VW health education program and provided feedback on the usability, design and satisfaction of the intervention at baseline and completion. A mixed-methods approach was used to analyze the participant perceptions of the intervention.

Results

Overall, there were positive participant perceptions of the VW experience. There was unanimous high satisfaction with the graphical interface appearance and ease of use. Participants placed value on the convenience, accessibility, and social connectivity of the remote program as well as the novelty of the simulation platform presentations, which aided in memorability of key concepts. Greater than 80% of participants reported that the program improved their health knowledge and helped to maintain better health habits.

Conclusions

Our pilot study revealed the feasibility and acceptability of an innovative VW-based CR program among cardiac patients. This novel delivery method for CR has the potential to influence healthy lifestyle change and to increase accessibility to vulnerable populations with higher cardiovascular disease burdens.

The role of cardiac rehabilitation in patients with heart disease

Cardiac rehabilitation is a valuable treatment for patients with a broad spectrum of cardiac disease. Current guidelines support its use in patients after acute coronary syndrome, coronary artery bypass grafting, coronary stent placement, valve surgery, and stable chronic systolic heart failure. Its use in these conditions is supported by a robust body of research demonstrating improved clinical outcomes. Despite this evidence, cardiac rehabilitation referral and attendance remains low and interventions to increase its use need to be developed.

Community health service center-based cardiac rehabilitation in patients with coronary heart disease: a prospective study

BACKGROUND

Despite considerable efforts to encourage participation, even in some developed countries, proportion of patients participating in institution-based cardiac rehabilitation (CR) programs remained sub-optimal. The present study was designed to investigate the acceptability of community health service center (CHSC)-based Cardiac Rehabilitation (CR), and examine its effectiveness in terms of changes in quality of life (QOL), psychological state and exercise capacity.

METHODS

A consecutive series of eligible patients was recruited from the health registration system of two CHSCs in Shijiazhuang, Hebei, China. Patients in intervention site were provided with CR (CR-group) while patients in non-intervention site were offered the usual care (UC-group). Data regarding health-related QOL (HRQoL), psychological state and exercise capacity (6-min walk test = 6MWT) were collected and compared at baseline and at 6 months post-intervention.

RESULTS

Among invited patients eligible for CR program, 65.3% participated, while 5.3% of the participants dropped out during follow-up. Patients in CR-group showed significant decrease in the scores for anxiety and depression as per the Hospital Anxiety and Depression Scale (HADS), along with marked increases in the Short-Form Health Survey (SF-12)-based Physical (PCS) and Mental Component Summary (MCS) scores. Moreover, the measurement of 6MWT showed a significant increase of 57.42 m walking distance among CR patients in contrast with a slight increase among UC patients.

CONCLUSIONS

Given the high participation and low withdrawal along with considerable improvements in HRQoL, psychological state and exercise capacity, CHSC was likely to be the optimal setting for implementing CR for patients with CHD in China.

Increasing Cardiac Rehabilitation Participation From 20% to 70%: A Road Map From the Million Hearts Cardiac Rehabilitation Collaborative

The primary aim of the Million Hearts initiative is to prevent 1 million cardiovascular events over 5 years. Concordant with the Million Hearts' focus on achieving more than 70% performance in the "ABCS" of aspirin for those at risk, blood pressure control, cholesterol management, and smoking cessation, we outline the cardiovascular events that would be prevented and a road map to achieve more than 70% participation in cardiac rehabilitation (CR)/secondary prevention programs by the year 2022. Cardiac rehabilitation is a class Ia recommendation of the American Heart Association and the American College of Cardiology after myocardial infarction or coronary revascularization, promotes the ABCS along with lifestyle counseling and exercise, and is associated with decreased total mortality, cardiac mortality, and rehospitalizations. However, current participation rates for CR in the United States generally range from only 20% to 30%. This road map focuses on interventions, such as electronic medical record-based prompts and staffing liaisons that increase referrals of appropriate patients to CR, increase enrollment of appropriate individuals into CR, and increase adherence to longer-term CR. We also calculate that increasing CR participation from 20% to 70% would save 25,000 lives and prevent 180,000 hospitalizations annually in the United States.

Developing an Adapted Cardiac Rehabilitation Training for Home Care Clinicians: PATIENT PERSPECTIVES, CLINICIAN KNOWLEDGE, AND CURRICULUM OVERVIEW

PURPOSE

There is limited evidence that home care clinicians receive education on the core competencies of cardiac rehabilitation (CR). This article describes the development and implementation of a CR training program adapted for home care clinicians, which incorporated the viewpoints of homebound patients with cardiovascular disease.

METHODS

Literature and guideline reviews were performed to glean curriculum content, supplemented with themes identified among patients and clinicians. Semistructured interviews were conducted with homebound patients regarding their perspectives on living with cardiovascular disease and focus groups were held with home care clinicians regarding their perspectives on caring for these patients. Transcripts were analyzed with the constant comparative method. A 15-item questionnaire was administered to home care nurses and rehabilitation therapists pre- and posttraining, and responses were analyzed using a paired sample t test.

RESULTS

Three themes emerged among patients: (1) awareness of heart disease; (2) motivation and caregivers' importance; and (3) barriers to attendance at outpatient CR; and 2 additional themes among clinicians: (4) gaps in care transitions; and (5) educational needs. Questionnaire results demonstrated significantly increased knowledge posttraining compared with pretraining among home care clinicians (pretest mean = 12.81; posttest mean = 14.63, P < .001). There was no significant difference between scores for nurses and rehabilitation therapists.

CONCLUSIONS

Home care clinicians respond well to an adapted CR training to improve care for homebound patients with cardiovascular disease. Clinicians who participated in the training demonstrated an increase in their knowledge and skills of the core competencies for CR.
