The content and characteristics of face-to-face interventions to encourage patients' enrollment in cardiac rehabilitation; a scoping review

PURPOSE

To provide an overview of the content and characteristics of face-to-face interventions to encourage enrollment in exercise-based cardiac rehabilitation (CR).

METHODS

Following a published protocol describing the methods, six databases were searched. The search was limited to studies published from January 2000 to December 2021. Two reviewers independently performed study selection and data extraction.

RESULTS

5583 studies were identified and 20 studies with a variety of study designs met the inclusion criteria. Eight studies specified important content in face-to-face interventions to be: Education, problem-solving, support of autonomy, exploring reasons for change, emotional and cognitive support while showing understanding. Studies targeting patients' experiences used motivational interviewing and addressed worries and anticipated difficulties. Intention to attend, CR barriers, practical barriers, exercise self-efficacy, and patients asking questions supported enrollment. Reassurance could lead to nonattendance if patients had a high degree of worry and distress.

CONCLUSION

Face-to-face interventions are important to support patients' enrollment in CR and should integrate a person-centered dialogue exploring reasons for change and providing support to overcome barriers. Focus on the patients' perspectives, the mechanisms of change, and the evaluation of the intervention to inform implementation should be further explored.Implications for RehabilitationIn-hospital face-to-face interventions support enrollment in cardiac rehabilitation (CR) in patients with ischemic heart disease.This study suggests that individual worries and barriers toward CR should be jointly explored while considering patients' capacity for making choices as well as their vulnerability.Patients should be encouraged to ask questions.A too strong focus on reassurance and problem-solving can impede enrollment.

A Systematic Review of Clinical Practice Guidelines and Consensus Statements for Cardiac Rehabilitation Delivery: Consensus, Divergence, and Important Knowledge Gaps

BACKGROUND

After 2020, clinical practice recommendations have been released to inform cardiac rehabilitation (CR) programs of best practices for post-COVID programming. The objective of this systematic review was to identify and summarize recommendations from clinical practice guidelines (CPGs) and consensus statements for CR delivery postpandemic.

METHODS

Five databases (March 2020 through April 2023), grey literature and Web sites of CR international associations were searched. Inclusion criteria were local, national, and international association-endorsed CPGs, and/or position, expert, and scientific statements related to CR delivery (program models, program elements, and core components). Two researchers independently screened the citations for inclusion. The Appraisal of Guidelines for Research and Evaluation (AGREE) II was used for quality assessment. Results were analyzed in accordance with the Synthesis Without Meta-analysis (SWiM) reporting guidelines.

RESULTS

Overall, 4890 records were identified; 4 CPGs, 9 position/scientific statements, and 6 expert/Delphi consensus papers were included. All guidelines/statements included information related to program delivery models, with 95% endorsing the use of virtual, hybrid, home-based, and telerehabilitation, especially during the pandemic. Outside of the context of COVID-19, program components including referral, CR indications, CR contraindications, timing, and structure were included in the 4 CPGs and 2 of 15 statements. Recommendations related to CR core components were primarily focused on exercise, with no changes since before the pandemic except for COVID-19 considerations for safety. One guideline was specific to women, and 1 scientific statement to heart failure with preserved ejection fraction.

CONCLUSIONS

Although 19 documents were identified, CR delivery in low resource settings and for culturally and linguistically diverse populations require attention. Additionally, few recommendations on nutrition, psychosocial counselling, and patient education were reported.

Behavioural and psychological telehealth support for people with cardiac conditions: randomized trial of the 'back on track' self-management programme

AIMS

Behaviour modification and mood management are essential to recovery after a cardiac event. Recent times have seen a major shift to remote delivery of cardiac services. This study assessed behavioural and psychological outcomes of the Back on Track online self-management programme, comparing the programme undertaken alone (self-directed) vs. with telephone support (supported). Relevance for people with depression was also assessed.

METHODS AND RESULTS

Participants with cardiac conditions (n = 122) were randomly assigned to self-directed or supported groups and given access to the online programme for 2 months. The programme addressed depression, anxiety, physical activity, and healthy eating. Supported group participants also received two telephone sessions facilitated by a trained counsellor to further enhance their self-management skills and engagement with the online modules. The Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, and Active Australia Survey and Diet Quality Tool were administered at baseline, 2, and 6 months. χ2 tests were used to compare self-directed and supported groups. Cochrane's Q tests assessed changes over time in depression, anxiety, and physical activity (PA) and healthy diet guideline achievement. Participants in both groups showed reduced depression rates (self-directed, P < 0.05) and increased PA after programme completion (both groups, P < 0.05). Amongst those classified as depressed at baseline, significantly fewer were classified as depressed over time (P < 0.001) and significantly more were achieving the PA guidelines (P < 0.01) compared to those who were not depressed at baseline.

CONCLUSIONS

The Back on Track telehealth programme was effective in assisting with behavioural and emotional recovery after a cardiac event. The programme may be particularly beneficial for those who are depressed early in their recovery period.

Barriers to Participation in Cardiac Rehabilitation Among Patients with Coronary Heart Disease After Reperfusion Therapy: A Scoping Review

Patients with coronary heart disease (CHD) experience many barriers to participate in cardiac rehabilitation (CR) programs. Several studies identify barriers that can affect participation in CR among patients with CHD after reperfusion therapy. However, there has yet to be a review specifically in this population. This review aims to identify the literature systematically that analyzes the barriers that affect the participation of CHD patients after reperfusion therapy in implementing the CR program. This study used the Preferred Reporting Item for PRISMA Extension for Scoping Reviews (PRISMA-ScR) with databases PubMed, ScienceDirect, EBSCO-hosted Academic Search Complete, Scopus, Taylor & Francis, and Sage Journals. The keywords used in English were "coronary artery disease OR myocardial infarction OR cardiovascular disease OR heart disease" AND "Barrier OR obstacle", AND "percutaneous coronary intervention OR PCI OR angioplasty OR coronary artery bypass graft surgery OR CABG" AND "cardiac rehabilitation OR rehabilitation OR recovery". The inclusion criteria in this review were full-text articles in English, articles with a descriptive, cross-sectional, and cohort design with a minimum of 100 participants that discussed barriers to participation in patients with CHD after undergoing reperfusion therapy, and the CR phases such as I, II, III, and IV have also been identified. Based on the initial search, there are 23 relevant studies out of 7400. The results of this study reported that most of the participants from the studies analyzed had a low level of participation in CR (≤50%). We classify the factors that affect the level of CR participation into five categories: individual factors, health history, environmental, logistical, and health system. The most reported barriers in each category were age, comorbidities, lack of support from friends, family and health workers, distance or travel time, and cost and economic status. Professional health workers, especially nurses, can identify various barriers that patients feel so that they can increase their participation in attending CR.

Cognitive Behavioral Therapy Enhances Survival in Cardiac Patients Aged Under 60: 14-YEAR OUTCOMES OF THE BEATING HEART PROBLEMS PROGRAM TRIAL

PURPOSE

To optimize recovery and improve prognosis, people who have had an acute cardiac event (ACE) need support to manage their cardiac risk. In 2008, we conducted a randomized controlled trial (RCT) of Beating Heart Problems (BHP) , an 8-wk group program based on cognitive behavioral therapy (CBT) and motivational interviewing (MI), designed to improve behavioral and mental health. This study investigated 14-yr mortality status for RCT participants in order to evaluate the survival impact of the BHP program.

METHODS

In 2021, mortality data on 275 participants from the earlier RCT were obtained from the Australian National Death Index. Survival analysis was undertaken to investigate differences in survival for participants in the treatment and control groups.

RESULTS

Over the 14-yr follow-up period, there were 52 deaths (18.9%). For those aged <60 yr, there was a significant survival benefit to program participation, with 3% deaths in the treatment group and 13% deaths in the control group ( P = .022). For those aged ≥60 yr, the death rate was identical in both groups (30%). Other significant predictors of mortality included older age, higher 2-yr risk score, lower functional capacity, lower self-rated health, and having no private health insurance.

CONCLUSIONS

Participation in the BHP conferred a survival benefit for patients aged <60 yr but not for participants overall. The findings highlight the long-term benefit of behavioral and psychosocial management of cardiac risk through CBT and MI for those who are younger at the time of their first ACE.

Unmet Needs for Cardiac Rehabilitation in Africa: A Perennial Gap in the Management of Individuals with Cardiac Diseases

Cardiac rehabilitation (CR) is a standard model of care, and an established component of comprehensive care that has been proven to reduce mortality and morbidity in patients with cardiac diseases. International clinical practice guidelines routinely recommend that cardiac patients participate in CR programs for comprehensive secondary prevention. However, there is scant guidance on how to deliver these programs in low-resourced settings. This dearth of clinical practice guidelines may be an indication of low emphasis placed on CR as a component of cardiac health services in low-income countries, especially in Africa. Indeed, CR programs are almost non-existent in Africa despite the unmet need for CR in patients with ischemic heart disease in Africa reported to be about one million. This figure represents the highest unmet need of any World Health Organization region, and is colossal given the projected accelerated increases in incidence of cardiovascular diseases (CVD) in the region. This narrative review explored the availability of CR programs, potential barriers to CR and strategies that can mitigate such barriers in Africa.

Prehabilitation in elective patients undergoing cardiac surgery: a randomised control trial (THE PrEPS TRIAL) - a study protocol

INTRODUCTION

Prehabilitation prior to surgery has been shown to reduce postoperative complications, reduce length of hospital stay and improve quality of life after cancer and limb reconstruction surgery. However, there are minimal data on the impact of prehabilitation in patients undergoing cardiac surgery, despite the fact these patients are generally older and have more comorbidities and frailty. This trial will assess the feasibility and impact of a prehabilitation intervention consisting of exercise and inspiratory muscle training on preoperative functional exercise capacity in adult patients awaiting elective cardiac surgery, and determine any impact on clinical outcomes after surgery.

METHODS AND ANALYSIS

PrEPS is a randomised controlled single-centre trial recruiting 180 participants undergoing elective cardiac surgery. Participants will be randomised in a 1:1 ratio to standard presurgical care or standard care plus a prehabilitation intervention. The primary outcome will be change in functional exercise capacity measured as change in the 6 min walk test distance from baseline. Secondary outcomes will evaluate the impact of prehabilitation on preoperative and postoperative outcomes including; respiratory function, health-related quality of life, anxiety and depression, frailty, and postoperative complications and resource use. This trial will evaluate if a prehabilitation intervention can improve preoperative physical function, inspiratory muscle function, frailty and quality of life prior to surgery in elective patients awaiting cardiac surgery, and impact postoperative outcomes.

ETHICS AND DISSEMINATION

A favourable opinion was given by the Sheffield Research Ethics Committee in 2019. Trial findings will be disseminated to patients, clinicians, commissioning groups and through peer-reviewed publication.

Trends in cardiac rehabilitation enrollment post-coronary artery bypass grafting upon implementation of automatic referral in Southeast Asia: A retrospective cohort study

Introduction: Cardiac rehabilitation (CR) is an effective but underutilized intervention. Strategies have been identified to increase its use, but there is paucity of data testing them in low-resource settings. We sought to determine the effect of automatic referral post-coronary artery bypass graft (CABG) surgery on CR enrollment.

Methods: This is a retrospective cohort study assessing cardiac patients referred to CR at a tertiary center in Southeast Asia from 2013 to 2019. The paper-based pathway was introduced at the end of 2012. The checklist with automatic CR referral on the third day post-operation prompted a nurse to educate the patient about CR, initiate phase 1 and encourage enrollment in phase 2. Patients who were not eligible for the pathway for administrative or clinical reasons were referred at the discretion of the attending physician (i.e., usual care). Enrollment was defined as attendance at≥1 CR visit.

Results: Of 4792 patients referred during the study period, 394 enrolled in CR. Significantly more patients referred automatically enrolled compared to usual care (225 [11.8%] vs. 169 [5.8%]; OR=2.2, 95% CI=1.8-2.7), with increases up to 23.4% enrollment in 2014 (vs. average enrollment rate of 5.9% under usual referral). Patients who enrolled following automatic referral were significantly younger and more often employed (both P<0.001); no other differences were observed.

Conclusion: In a lower-resource, Southeast Asian setting, automatic CR referral is associated with over two times greater enrollment in phase 2 CR, although efforts to maintain this effect are required.

Getting "Back on Track" After a Cardiac Event: Protocol for a Randomized Controlled Trial of a Web-Based Self-management Program

Background

After a cardiac event, a large majority of patients with cardiac conditions do not achieve recommended behavior change targets for secondary prevention. Mental health issues can also impact the ability to engage in health behavior change. There is a need for innovative, flexible, and theory-driven eHealth programs, which include evidence-based strategies to assist patients with cardiac conditions with their recovery, especially in behavioral and emotional self-management.

Objective

The aim of this study is to determine the short- and longer-term behavioral and emotional well-being outcomes of the Back on Track web-based self-management program. In addition, this study will test whether there is enhanced benefit of providing one-on-one telephone support from a trained lifestyle counselor, over and above benefit obtained through completing the web-based program alone.

Methods

People who have experienced a cardiac event in the previous 12 months and have access to the internet will be eligible for this study (N=120). Participants will be randomly assigned to one of the two study conditions: either “self-directed” completion of the Back on Track program (without assistance) or “supported” completion of the Back on Track program (additional 2 telephone sessions with a lifestyle counselor). All participants will have access to the web-based Back on Track program for 2 months. Telephone sessions with the supported arm participants will occur at approximately 2 and 6 weeks post enrollment. Measures will be assessed at baseline, and then 2 and 6 months later. Outcome measures assessed at all 3 timepoints include dietary intake, physical activity and sitting time, smoking status, anxiety and depression, stage of change, and self-efficacy in relation to behavioral and emotional self-management, quality of life, and self-rated health and well-being. A demographic questionnaire will be included at baseline only and program acceptability at 2 months only.

Results

Recruitment began in May 2020 and concluded in August 2021. Data collection for the 6-month follow-up will be completed by February 2022, and data analysis and publication of results will be completed by June 2022. A total of 122 participants were enrolled in this study.

Conclusions

The Back on Track trial will enable us to quantify the behavioral and emotional improvements obtained and maintained for patients with cardiac conditions and, in particular, to compare two modes of delivery: (1) fully self-directed delivery and (2) supported by a lifestyle counselor. We anticipate that the web-based Back on Track program will assist patients in their recovery and self-management after an acute event, and represents an effective, flexible, and easily accessible adjunct to center-based rehabilitation programs.

Evaluating Exercise Progression in an Australian Cardiac Rehabilitation Program: Should Cardiac Intervention, Age, or Physical Capacity Be Considered?

Progression of prescribed exercise is important to facilitate attainment of optimal physical capacity during cardiac rehabilitation. However, it is not clear how often exercise is progressed or to what extent. This study evaluated whether exercise progression during clinical cardiac rehabilitation was different between cardiovascular treatment, age, or initial physical capacity. The prescribed exercise of sixty patients who completed 12 sessions of outpatient cardiac rehabilitation at a major Australian metropolitan hospital was evaluated. The prescribed aerobic exercise dose was progressed using intensity rather than duration, while repetitions and weight lifted were utilised to progress resistance training dose. Cardiovascular treatment or age did not influence exercise progression, while initial physical capacity and strength did. Aerobic exercise intensity relative to initial physical capacity was progressed from the first session to the last session for those with high (from mean (95%CI) 44.6% (42.2-47.0) to 68.3% (63.5-73.1); p < 0.001) and moderate physical capacity at admission (from 53.0% (50.7-55.3) to 76.3% (71.2-81.4); p < 0.001), but not in those with low physical capacity (from 67.3% (63.7-70.9) to 85.0% (73.7-96.2); p = 0.336). The initial prescription for those with low physical capacity was proportionately higher than for those with high capacity (p < 0.001). Exercise testing should be recommended in guidelines to facilitate appropriate exercise prescription and progression.

Enhancing the appeal of cardiac rehabilitation for women: development and pilot testing of a women-only yoga cardiac rehabilitation programme

AIMS

Despite its demonstrated benefits, cardiac rehabilitation (CR) attendance, and completion is suboptimal, particularly in women. The aims of this study were (i) to develop and pilot test a women-only yoga-based CR programme (the Women's Yoga CR Programme; WYCRP); (ii) to investigate programme acceptability; and (iii) to investigate attendance and completion of the WYCRP and continuation to Phase III community-based CR.

METHODS AND RESULTS

Women eligible for CR at a tertiary hospital in Melbourne, Australia were recruited. Over a 6-month period in 2019, they were offered the WYCRP or usual CR. The WYCRP involved attendance at a 1-h yoga session following the usual 1-h mixed-sex education session, over a 7-week period. Participants completed pre- and post-programme questionnaires and attended focus groups to assess programme acceptability. Rates of attendance, completion, and continuation for the WYCRP were recorded and compared to those for the standard CR programme offered in 2018. In total, 27 women were eligible for the study and attended the initial CR assessment. Of those, 22 (81%) attended the WYCRP, 1 (4%) attended usual CR, and 4 (15%) did not attend CR. Ratings of programme acceptability were consistently positive; qualitative comments highlighted both physical and emotional benefits. While attendance at the WYCRP was not significantly higher than for usual CR the previous year (81% vs. 76%; P = 0.40), CR completion, and continuation were (95% vs. 56%; P = 0.02, and 72% vs. 12%; P < 0.001, respectively).

CONCLUSION

This pilot study has demonstrated that women-only yoga-based CR is appealing to women and can improve women's CR completion and continuation. These preliminary findings support further development of women-only and yoga-based CR options.

Individuals' Intention to Engage in Outpatient Cardiac Rehabilitation Programs: Prediction Based on an Enhanced Model

Motivation is an important factor in encouraging individuals to attend rehabilitation and underpins many approaches to engagement. The aims of this study were to develop an accurate model able to predict individual intention to engage in outpatient cardiac rehabilitation (CR) programs based on the first stage of the Model of Therapeutic Engagement integrated into a socio-environmental context. The cross-sectional study in the cardiology ward of an Australian hospital included a total of 217 individuals referred to outpatient CR. Through an ordinal logistic regression, the effect of random forest (RF)-selected profile features on individual intention to engage in outpatient CR was explored. The RF based on the conditional inference trees predicted the intention to engage in outpatient CR with high accuracy. The findings highlighted the significant roles of individuals' 'willingness to consider the treatment', 'perceived self-efficacy' and 'perceived need for rehabilitation' in their intention, while the involvement of 'barriers to engagement' and 'demographic and medical factors' was not evident.

Current challenges in cardiac rehabilitation: strategies to overcome social factors and attendance barriers

INTRODUCTION

Cardiac rehabilitation (CR) significantly reduces secondary cardiovascular events and mortality and is a class 1A recommendation by the American Heart Association (AHA) and American College of Cardiology (ACC). However, it remains an underutilized intervention and many eligible patients fail to enroll or complete CR programs. The aim of this review is to identify barriers to CR attendance and discuss strategies to overcome them.

AREAS COVERED

Specific barriers to CR attendance and participation will be reviewed. This will be followed by a discussion of solutions/strategies to help overcome these barriers with a particular focus on home-based CR (HBCR).

EXPERT OPINION

HBCR alone or in combination with center-based CR (CBCR) can help overcome many barriers to traditional CBCR participation, such as schedule flexibility, time commitment, travel distance, cost, and patient preference. Using remote coaching with indirect exercise supervision, HBCR has been shown to have comparable benefits to CBCR. At this time, however, funding remains the main barrier to universal incorporation of HBCR into health systems, necessitating the need for additional cost benefit analysis and outcome studies. Ultimately, the choice for HBCR should be based on patient preference and availability of resources.

Cardiac Rehabilitation Knowledge and Attitudes of Cardiology Fellows

PURPOSE

Cardiac rehabilitation (CR) is underutilized with only 8-31% of eligible patients participating. Lack of referral and lack of physician endorsement are well-known barriers to participation. Physicians who lack insights regarding CR are less likely to refer patients and recommend it. Cardiology fellows are early career physicians who spend a significant amount of time treating patients eligible for CR. At one institution's cardiology fellowship program, we sought to assess fellow attitudes and knowledge base regarding CR and to determine their facilitators and barriers to CR endorsement and referral.

METHODS

University of Pittsburgh Department of Medicine Cardiology fellows were surveyed and interviewed to assess CR knowledge, attitudes, and perceived facilitators and barriers to CR endorsement and referral.

RESULTS

The cardiology fellows at this institution had strong belief in the benefits and cost-effectiveness of CR. Despite their support of CR, they had low CR knowledge scores. Perceived impediments to CR included complicated logistics of CR operations, limited communication between CR staff and fellows, limited time with patients, presumed patient barriers, perceived self-barriers, and poor understanding of referral processes (particularly as they varied in each hospital in which they rotated). Perceived supports to CR included greater awareness of evidence-based outcomes, awareness of patient-centered outcomes, pre-arranged order sets, and reminders for referral.

CONCLUSION

This study revealed perceptions of cardiology fellows at one institution regarding CR that have not been considered previously. Key barriers to endorsement and referral to CR were exposed as well as opportunities to overcome them. Fellowship training affords an important opportunity to improve CR education, and to potentially improve participation of eligible patients for this important aspect of care.

Home-Based Cardiac Rehabilitation: A SCIENTIFIC STATEMENT FROM THE AMERICAN ASSOCIATION OF CARDIOVASCULAR AND PULMONARY REHABILITATION, THE AMERICAN HEART ASSOCIATION, AND THE AMERICAN COLLEGE OF CARDIOLOGY

Cardiac rehabilitation (CR) is an evidence-based intervention that uses patient education, health behavior modification, and exercise training to improve secondary prevention outcomes in patients with cardiovascular disease. CR programs reduce morbidity and mortality rates in adults with ischemic heart disease, heart failure, or cardiac surgery but are significantly underused, with only a minority of eligible patients participating in CR in the United States. New delivery strategies are urgently needed to improve participation. One potential strategy is home-based CR (HBCR). In contrast to center-based CR services, which are provided in a medically supervised facility, HBCR relies on remote coaching with indirect exercise supervision and is provided mostly or entirely outside of the traditional center-based setting. Although HBCR has been successfully deployed in the United Kingdom, Canada, and other countries, most US healthcare organizations have little to no experience with such programs. The purpose of this scientific statement is to identify the core components, efficacy, strengths, limitations, evidence gaps, and research necessary to guide the future delivery of HBCR in the United States. Previous randomized trials have generated low- to moderate-strength evidence that HBCR and center-based CR can achieve similar improvements in 3- to 12-month clinical outcomes. Although HBCR appears to hold promise in expanding the use of CR to eligible patients, additional research and demonstration projects are needed to clarify, strengthen, and extend the HBCR evidence base for key subgroups, including older adults, women, underrepresented minority groups, and other higher-risk and understudied groups. In the interim, we conclude that HBCR may be a reasonable option for selected clinically stable low- to moderate-risk patients who are eligible for CR but cannot attend a traditional center-based CR program.

Cardiac rehabilitation: Appraisal of current evidence and utility of technology aided home-based cardiac rehabilitation

Cardiac rehabilitation (CR) is an evidence-based intervention that uses exercise training, health behaviour modification, medication adherence and psychological counselling to improve secondary prevention outcomes in patients with cardiovascular disease. CR programs reduce morbidity and mortality rates in adults with ischemic heart disease, following coronary intervention, heart failure, or cardiac surgery. These are significantly underused, with only a minority of eligible patients participating in CR in India. Novel delivery strategies and CR endorsement by healthcare organizations are urgently needed to improve participation. One potential strategy is home-based CR (HBCR). Differing from centre-based CR services, which are provided in a medically supervised facility, HBCR relies on remote coaching with indirect exercise supervision. It is provided mostly or entirely outside of the traditional centre-based setting and could be facilitated by the aid of technology and web based applications. The purpose of this appraisal is to identify the core components, efficacy, strengths, limitations, evidence gaps, and research necessary to guide the future delivery of HBCR. This appears to hold promise in expanding the use of CR to eligible patients. Additional research and demonstration projects are needed to clarify, strengthen, and extend the HBCR evidence base for key subgroups, including older adults, women, underrepresented minority groups, and people in remote and rural areas. HBCR may be a reasonable option for a selected group of patients and could be a game changer in low- and middle-income countries who are eligible for CR.

A Review of Models Used for Investigating Barriers to Healthcare Access in Australia

Understanding barriers to healthcare access is a multifaceted challenge, which is often highly diverse depending on location and the prevalent surroundings. The barriers can range from transport accessibility to socio-economic conditions, ethnicity and various patient characteristics. Australia has one of the best healthcare systems in the world; however, there are several concerns surrounding its accessibility, primarily due to the vast geographical area it encompasses. This review study is an attempt to understand the various modeling approaches used by researchers to analyze diverse barriers related to specific disease types and the various areal distributions in the country. In terms of barriers, the most affected people are those living in rural and remote parts, and the situation is even worse for indigenous people. These models have mostly focused on the use of statistical models and spatial modeling. The review reveals that most of the focus has been on cancer-related studies and understanding accessibility among the rural and urban population. Future work should focus on further categorizing the population based on indigeneity, migration status and the use of advanced computational models. This article should not be considered an exhaustive review of every aspect as each section deserves a separate review of its own. However, it highlights all the key points, covered under several facets which can be used by researchers and policymakers to understand the current limitations and the steps that need to be taken to improve health accessibility.

Challenges in Managing Acute Cardiovascular Diseases and Follow Up Care in Rural Areas: A Narrative Review

This narrative review explores relevant literature that is related to the challenges in implementing evidence-based management for clinicians in rural and remote areas, while primarily focussing on management of acute coronary syndrome (ACS) and follow up care. A targeted literature search around rural/urban differences in the management of ACS, cardiovascular disease, and cardiac rehabilitation identified multiple issues that are related to access, including the ability to pay, transport and geographic distances, delays in patients seeking care, access to diagnostic testing, and timely treatment in an appropriate facility. Workforce shortages or lack of ready access to relevant expertise, cultural differences, and complexity that arises from comorbidities and from geographical isolation amplified diagnostic challenges. Given the urgency in management of ACS, rural clinicians must act quickly to achieve optimal patient outcomes. New technologies and quality improvement approaches enable better access to rapid diagnosis, as well as specialist input and care. Achieving an uptake of cardiac rehabilitation in rural and remote settings poses challenges that may reduce with the use of alternative models to centre-based rehabilitation and use of modern technologies. Expediting improvement in cardiovascular outcomes and reducing rural disparities requires system changes and that clinicians embrace attention to prevention, emergency management, and follow up care in rural contexts.

Is Exercise Prescription in Cardiac Rehabilitation Influenced by Physical Capacity or Cardiac Intervention?

This study investigated the influence of cardiac intervention and physical capacity of individuals attending an Australian outpatient cardiac rehabilitation program on the initial exercise prescription. A total of 85 patients commencing outpatient cardiac rehabilitation at a major metropolitan hospital had their physical capacity assessed by an incremental shuttle walk test, and the initial aerobic exercise intensity and resistance training load prescribed were recorded. Physical capacity was lower in surgical patients than nonsurgical patients. While physical capacity was higher in younger compared with older surgical patients, there was no difference between younger and older nonsurgical patients. The initial exercise intensity did not differ between surgical and nonsurgical patients. This study highlights the importance of preprogram exercise testing to enable exercise prescription to be individualized according to actual physical capacity, rather than symptoms, comorbidities and age, in order to maximize the benefit of cardiac rehabilitation.

Factors associated with non-participation in and dropout from cardiac rehabilitation programmes: a systematic review of prospective cohort studies

BACKGROUND

Although evidence exists for the efficacy of cardiac rehabilitation programmes to reduce morbidity and mortality among patients with cardiovascular disease, cardiac rehabilitation programmes are underused. We aimed systematically to review the evidence from prospective cohort studies on factors associated with non-participation in and/or dropping out from cardiac rehabilitation programmes.

METHODS

MedLine, Embase, Scopus, Open Grey and Cochrane Database were searched for relevant publications from inception to February 2018. Search terms included (a) coronary heart disease and other cardiac conditions; (b) cardiac rehabilitation and secondary prevention; and (c) non-participation in and/or dropout. Databases were searched following the PRISMA statement. Study selection, data extraction and the assessment of study quality were performed in duplicate.

RESULTS

We selected 43 studies with a total of 63,425 patients from 10 different countries that met the inclusion criteria. Factors associated with non-participation in and dropout from cardiac rehabilitation were grouped into six broad categories: intrapersonal factors, clinical factors, interpersonal factors, logistical factors, cardiac rehabilitation programme factors and health system factors. We found that clinical factors, logistical factors and health system factors were the main factors assessed for non-participation in cardiac rehabilitation. We also found differences between the factors associated with non-participation and dropout.

CONCLUSIONS

Several factors were determinant for non-participation in and dropout from cardiac rehabilitation. These findings could be useful to clinicians and policymakers for developing interventions aimed at improving participation and completion of cardiac rehabilitation, such as E-health or home-based delivery programmes.

Cardiac Rehabilitation for Women: A Systematic Review of Barriers and Solutions

Cardiac rehabilitation (CR) services improve various clinical outcomes in patients with cardiovascular disease, but such services are underutilized, particularly in women. The aim of this study was to identify evidence-based barriers and solutions for CR participation in women. A literature search was carried out using PubMed, EMBASE, Cochrane, OVID/Medline, and CINAHL to identify studies that have assessed barriers and/or solutions to CR participation. Titles and abstracts were screened, and then the full-text of articles that met study criteria were reviewed. We identified 24 studies that studied barriers to CR participation in women and 31 studies that assessed the impact of various interventions to improve CR referral, enrollment, and/or completion of CR in women. Patient-level barriers included lower education level, multiple comorbid conditions, non-English native language, lack of social support, and high burden of family responsibilities. We found support for the use of automatic referral and assisted enrollment to improve CR participation. A small number of studies suggest that incentive-based strategies, as well as home-based programs, may contribute to improving CR attendance and completion rates. A systematic approach to CR referral, including automatic CR referral, may help overcome barriers to CR referral in women and should be implemented in clinical practice. However, more studies are needed to help identify the best methods to improve CR attendance and completion of CR rates in women.

Participation Rates, Process Monitoring, and Quality Improvement Among Cardiac Rehabilitation Programs in the United States: A NATIONAL SURVEY

PURPOSE

Although strategies exist for improving cardiac rehabilitation (CR) participation rates, it is unclear how frequently these strategies are used and what efforts are being made by CR programs to improve participation rates.

METHODS

We surveyed all CR program directors in the American Association of Cardiovascular and Pulmonary Rehabilitation's database. Data collection included program characteristics, the use of specific referral and recruitment strategies, and self-reported program participation rates.

RESULTS

Between 2007 and 2012, 49% of programs measured referral of inpatients from the hospital, 21% measured outpatient referral from office/clinic, 71% measured program enrollment, and 74% measured program completion rates. Program-reported participation rates (interquartile range) were 68% (32-90) for hospital referral, 35% (15-60) for office/clinic referral, 70% (46-80) for enrollment, and 75% (62-82) for program completion. The majority of programs utilized a hospital-based systematic referral, liaison-facilitated referral, or inpatient CR program referral (64%, 68%, and 60% of the time, respectively). Early appointments (<2 weeks) were utilized by 35%, and consistent phone call appointment reminders were utilized by 50% of programs. Quality improvement (QI) projects were performed by about half of CR programs. Measurement of participation rates was highly correlated with performing QI projects (P < .0001.)

CONCLUSIONS

: Although programs are aware of participation rate gaps, the monitoring of participation rates is suboptimal, QI initiatives are infrequent, and proven strategies for increasing patient participation are inconsistently utilized. These issues likely contribute to the national CR participation gap and may prove to be useful targets for national QI initiatives.

Smoking and cardiac rehabilitation participation: Associations with referral, attendance and adherence

OBJECTIVE

Continued smoking after a cardiac event greatly increases mortality risk. Smoking cessation and participation in cardiac rehabilitation (CR) are effective in reducing morbidity and mortality. However, these two behaviors may interact; those who smoke may be less likely to access or complete CR. This review explores the association between smoking status and CR referral, attendance, and adherence.

METHODS

A systematic literature search was conducted examining associations between smoking status and CR referral, attendance and completion in peer-reviewed studies published through July 1st, 2014. For inclusion, studies had to report data on outpatient CR referral, attendance or completion rates and smoking status had to be considered as a variable associated with these outcomes.

RESULTS

Fifty-six studies met inclusion criteria. In summary, a history of smoking was associated with an increased likelihood of referral to CR. However, smoking status also predicted not attending CR and was a strong predictor of CR dropout.

CONCLUSION

Continued smoking after a cardiac event predicts lack of attendance in, and completion of CR. The issue of smoking following a coronary event deserves renewed attention.

Education of Physicians and Implementation of a Formal Referral System Can Improve Cardiac Rehabilitation Referral and Participation Rates after Percutaneous Coronary Intervention

BACKGROUND

Cardiac rehabilitation (CR) is an effective preventive measure that remains underutilised in the United States. The study aimed to determine the CR referral rate (RR) after percutaneous coronary intervention (PCI) at an academic tertiary care centre, identify barriers to referral, and evaluate awareness of CR benefits and indications (CRBI) among cardiologists. Subsequently, it aimed to evaluate if an intervention consisting of physicians' education about CRBI and implementation of a formal CR referral system could improve RR and consequently participation rate (PR).

METHODS

Data were retrospectively collected for all consecutive patients who underwent PCI over 12 months. Referral rate was determined and variables were compared for differences between referred and non-referred patients. A questionnaire was distributed among the physicians in the Division of Cardiology to assess awareness of CRBI and referral practice patterns. After implementation of the intervention, data were collected retrospectively for consecutive patients who underwent PCI in the following six months. Referral rate and changes in PRs were determined.

RESULTS

Prior to the intervention, RR was 17.6%. Different barriers were identified, but the questionnaire revealed lack of physicians' awareness of CRBI and inconsistent referral patterns. After the intervention, RR increased to 88.96% (Odds Ratio 37.73, 95% CI 21.34-66.70, p<0.0001) and PR increased by 32.8% to reach 26%. Personal endorsement of CRBI by cardiologists known to patients increased CR program graduation rate by 35%.

CONCLUSIONS

Cardiologists' awareness of CRBI increases CR RR and their personal endorsement improves PR and compliance. Education of providers and implementation of a formal referral system can improve RR and PR.

Perceptions of exercise and quality of life in older patients in the United States during the first year following coronary artery bypass surgery

BACKGROUND AND PURPOSE

It is important for patients recovering from coronary artery bypass (CAB) surgery to initiate and maintain recommended exercise guidelines. The purpose of this qualitative study was to describe factors that influence adherence to exercise, and perceptions of activity limitations and health-related quality of life (QoL) in older patients recovering from CAB surgery.

SUBJECTS

Participants were 28 people aged 65 and older, prospectively recruited from a U.S. hospital following CAB surgery.

PROCEDURES

A qualitative description methodology was used to identify factors that influenced participants' feelings about exercise and QoL. Data were collected using phone interviews 3, 6, and 12 months after surgery. Data were coded by identifying significant statements, grouping them into meaningful units or "themes", and generating descriptions of participants' experiences and understandings.

RESULTS

Across time points, participants' most commonly described motivators were that it feels good to exercise, and belief that it improves physical health. The most commonly cited barriers to exercise were other time commitments, inclement weather, and pain/injury/illness related or unrelated to CAB surgery.

DISCUSSION AND CONCLUSION

Motivating themes remained consistent across the time intervals but the number of responses regarding barriers to exercise increased over time. A better understanding of the patient experience may help to promote exercise initiation and adherence following CAB surgery.

Case management training needs to support vocational rehabilitation for case managers and general practitioners: a survey study

BACKGROUND

The use of the biopsychosocial model of health and case management for effective vocational rehabilitation (VR) has been confirmed for many health conditions. While Case and Condition Managers (CCMPs) use this approach in their everyday work, little is known about their views on training needs. A review of the training curriculum for General Practitioners' (GPs) revealed little training in VR and the biopsychosocial model of care. This study aims to identify Case and Condition Managers and GPs perceptions of their training needs in relation to employability and VR.

METHODS

80 Case and Condition Managers and 304 GPs working in NHS Lanarkshire, providing a comparison group, were invited to participate in this study. A self-completion questionnaire was developed and circulated for online completion with a second round of hardcopy questionnaires distributed.

RESULTS

In total 45 responses were obtained from CCMPs, 5 from occupational health nurses (62% response rate) and 60 from GPs (20% response rate). CCMPs and the nursing group expressed a need for training but to a lesser extent than GP's. The GP responses demonstrated a need for high levels of training in case/condition management, the biopsychosocial model, legal and ethical issues associated with employment and VR, and management training.

CONCLUSIONS

This survey confirms a need for further training of CCMPs and that respondent GPs in one health board are not fully equipped to deal with patients employability and vocational needs. GPs also reported a lack of understanding about the role of Case and Condition managers. Training for these professional groups and others involved in multidisciplinary VR could improve competencies and mutual understanding among those advising patients on return-to-work.

Sex differences in cardiac rehabilitation enrollment: a meta-analysis

BACKGROUND

The present systematic review and meta-analysis examines studies published in the past 10 years that described cardiac rehabilitation (CR) enrollment among women and men, to determine whether a significant sex difference persists despite the evidence supporting the benefits of CR to women as well as men.

METHODS

Scopus, MEDLINE, CINAHL, PsycINFO, PubMed, and The Cochrane Library databases were systematically searched for peer-reviewed articles published from July 2000 to July 2011. Titles and abstracts were screened, and the 623 selected full-text articles were independently screened based on predefined inclusion/exclusion criteria (guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses; PRISMA) and assessed for quality using the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) statement form. The meta-analysis was undertaken using Review Manager software.

RESULTS

Twenty-six eligible observational studies reporting data for 297,719 participants (128,499 [43.2%] women) were included. On average, 45.0% of men and 38.5% of women enrolled in CR. In the pooled analysis, men were more likely to be enrolled in CR compared with women (female enrollment vs male enrollment odds ratio, 0.64; 95% confidence interval, 0.57-0.72; P < 0.00001). Heterogeneity was considered high (I(2) = 78%). In the subgroup analyses, systematic CR referral during inpatient tertiary care resulted in significantly greater enrollment among women than nonsystematic referral.

CONCLUSIONS

Overall, rates of CR enrollment among women are significantly lower compared with men, with women being 36% less likely to enroll in a rehabilitation program.

Cardiac rehabilitation barriers by rurality and socioeconomic status: a cross-sectional study

INTRODUCTION

Despite greater need, rural inhabitants and individuals of low socioeconomic status (SES) are less likely to undertake cardiac rehabilitation (CR). This study examined barriers to enrollment and participation in CR among these under-represented groups.

METHOD

Cardiac inpatients from 11 hospitals across Ontario were approached to participate in a larger study. Rurality was assessed by asking participants whether they lived within a 30-minute drive-time from the nearest hospital, with those >30 minutes considered "rural." Participants completed a sociodemographic survey, which included the MacArthur Scale of Subjective Social Status. One year later, they were mailed a survey which assessed CR utilization and included the Cardiac Rehabilitation Barriers Scale. In this cross-sectional study, CR utilization and barriers were compared by rurality and SES.

RESULTS

Of the 1809 (80.4%) retained, there were 215 (11.9%) rural participants, and the mean subjective SES was 6.37 ± 1.76. The mean CRBS score was 2.03 ± 0.73. Rural inhabitants reported attending significantly fewer CR sessions (p < .05), and greater CR barriers overall compared to urban inhabitants (p < .01). Patients of lower subjective SES were significantly less likely to be referred, enroll, and participate in CR, and reported significantly greater barriers to CR compared to their high SES counterparts (p < .01). Prominent barriers for both groups included distance, cost, and transportation problems. These relationships sustained adjustment, and a significant relationship between having undergone coronary artery bypass graft surgery and lower barriers was also identified.

CONCLUSIONS

The results confirm that rural inhabitants and patients of low SES experience greater barriers to CR utilization when compared to their urban, high SES counterparts. It is time to implement known strategies to overcome these barriers, to achieve equitable and greater use of CR.

An early appointment to outpatient cardiac rehabilitation at hospital discharge improves attendance at orientation: a randomized, single-blind, controlled trial

BACKGROUND

Outpatient cardiac rehabilitation (CR) decreases mortality rates but is underutilized. Current median time from hospital discharge to enrollment is 35 days. We hypothesized that an appointment within 10 days would improve attendance at CR orientation.

METHODS AND RESULTS

At hospital discharge, 148 patients with a nonsurgical qualifying diagnosis for CR were randomized to receive a CR orientation appointment either within 10 days (early) or at 35 days (standard). The primary end point was attendance at CR orientation. Secondary outcome measures were attendance at ≥1 exercise session, the total number of exercise sessions attended, completion of CR, and change in exercise training workload while in CR. Average age was 60±12 years; 56% of participants were male and 49% were black, with balanced baseline characteristics between groups. Median time (95% confidence interval) to orientation was 8.5 (7-13) versus 42 (35 to NA [not applicable]) days for the early and standard appointment groups, respectively (P<0.001). Attendance rates at the orientation session were 77% (57/74) versus 59% (44/74) in the early and standard appointment groups, respectively, which demonstrates a significant 18% absolute and 56% relative improvement (relative risk, 1.56; 95% confidence interval, 1.03-2.37; P=0.022). The number needed to treat was 5.7. There was no difference (P>0.05) in any of the secondary outcome measures, but statistical power for these end points was low. Safety analysis demonstrated no difference between groups in CR-related adverse events.

CONCLUSIONS

Early appointments for CR significantly improve attendance at orientation. This simple technique could potentially increase initial CR participation nationwide.

A systematic review of patient reported factors associated with uptake and completion of cardiovascular lifestyle behaviour change

BACKGROUND

Healthy lifestyles are an important facet of cardiovascular risk management. Unfortunately many individuals fail to engage with lifestyle change programmes. There are many factors that patients report as influencing their decisions about initiating lifestyle change. This is challenging for health care professionals who may lack the skills and time to address a broad range of barriers to lifestyle behaviour. Guidance on which factors to focus on during lifestyle consultations may assist healthcare professionals to hone their skills and knowledge leading to more productive patient interactions with ultimately better uptake of lifestyle behaviour change support. The aim of our study was to clarify which influences reported by patients predict uptake and completion of formal lifestyle change programmes.

METHODS

A systematic narrative review of quantitative observational studies reporting factors (influences) associated with uptake and completion of lifestyle behaviour change programmes. Quantitative observational studies involving patients at high risk of cardiovascular events were identified through electronic searching and screened against pre-defined selection criteria. Factors were extracted and organised into an existing qualitative framework.

RESULTS

374 factors were extracted from 32 studies. Factors most consistently associated with uptake of lifestyle change related to support from family and friends, transport and other costs, and beliefs about the causes of illness and lifestyle change. Depression and anxiety also appear to influence uptake as well as completion. Many factors show inconsistent patterns with respect to uptake and completion of lifestyle change programmes.

CONCLUSION

There are a small number of factors that consistently appear to influence uptake and completion of cardiovascular lifestyle behaviour change. These factors could be considered during patient consultations to promote a tailored approach to decision making about the most suitable type and level lifestyle behaviour change support.

Multidisciplinary outpatient rehabilitation following cardiac revascularization or valve surgery: patient-related factors for uptake

BACKGROUND

There are concerns in Europe regarding the service provision and accessibility of multidisciplinary cardiac rehabilitation (MDCR) in general, and particularly in ambulatory settings. This paper analyses the utilization of outpatient MDCR and its determinants after cardiac revascularization or valve surgery in Belgium.

METHODS

Claims rehabilitation data for all patients discharged in 2007 after a percutaneous cardiac intervention or cardiac surgery were available from the Belgian Common Sickness Funds Agency. Logistic regressions were performed to identify patients demographic and socioeconomic characteristics associated with the uptake of outpatient MDCR during the year following the hospital discharge.

RESULTS

A total of 29,021 patients were included. During the hospitalization for the cardiac procedure, 44% were offered inpatient MDCR. After discharge, only 15.6% followed at least one session of outpatient MDCR. The chance of attending outpatient MDCR was lower for female, disabled, and older patients, as well as unemployed patients. The absence of an authorized MDCR centre in the neighbourhood of the patient's residence decreased the chance of attending outpatient MDCR, while living in a neighbourhood with a high education and income level increased this probability.

CONCLUSION

These results confirm the low rates of MDCR attendance found in a previous study performed by the European Association of Cardiovascular Prevention and Rehabilitation. The study shows specific patient groups that should be targeted in priority, i.e. women, elderly, unemployed patients, disabled persons, and patients with a low socioeconomic status.

Adherence to a cardiac rehabilitation home program model of care: a comparison to a well-established traditional on-site supervised program

Despite the proven benefits of cardiac rehabilitation (CR), adherence to programs remains suboptimal. To improve adherence, alternative models of care, such as using home programs (HP), have been recommended. Little information exists, however, about its effect on adherence in real-world settings. Therefore, this study's primary objective was to compare adherence of patients in an HP and traditional on-site program (TP) model of CR. The secondary objective was to compare their clinical and demographic profiles and changes in cardiovascular fitness. We implemented a retrospective review of 200 consecutively enrolled patients who chose either a TP or HP model. Profile data was collected at intake assessment. Adherence, defined as attendance to prescheduled contacts or on-site visits in each respective cohort, served as a primary outcome measure. Secondary outcomes included completion of program and cardiopulmonary fitness levels at 6 months. We found that the HP cohort had patients who were significantly younger, male (significantly moreso than female), were more geographically removed from the on-site centre, were employed, and (or) had greater cardiopulmonary fitness at initiation. Similar mean attendance (p = 0.21) and completion rates (p = 0.22) were seen between models. Both groups attained similar gains in cardiovascular fitness (p = 0.79). Analysis of adherence shows the HP to be a suitable option for patients who face barriers for TP-CR participation.

The role of systematic inpatient cardiac rehabilitation referral in increasing equitable access and utilization

BACKGROUND

While systematic referral strategies have been shown to significantly increase cardiac rehabilitation (CR) enrollment to approximately 70%, whether utilization rates increase among patient groups who are traditionally underrepresented has yet to be established. This study compared CR utilization based on age, marital status, rurality, socioeconomic indicators, clinical risk, and comorbidities following systematic versus nonsystematic CR referral.

METHODS

Coronary artery disease inpatients (N = 2635) from 11 Ontario hospitals, utilizing either systematic (n = 8 wards) or nonsystematic referral strategies (n = 8 wards), completed a survey including sociodemographics and activity status. Clinical data were extracted from charts. At 1 year, 1680 participants completed a mailed survey that assessed CR utilization. The association of patient characteristics and referral strategy on CR utilization was tested using χ.

RESULTS

When compared to nonsystematic referral, systematic strategies resulted in significantly greater CR referral and enrollment among obese (32 vs 27% referred, P = .044; 33 vs 26% enrolled, P = .047) patients of lower socioeconomic status (41 vs 34% referred, P = .026; 42 vs 32% enrolled, P = .005); and lower activity status (63 vs 54% referred, P = .005; 62 vs 51% enrolled, P = .002). There was significantly greater enrollment among those of lower education (P = .04) when systematically referred; however, no significant differences in degree of CR participation based on referral strategy.

CONCLUSION

Up to 11% more socioeconomically disadvantaged patients and those with more risk factors utilized CR where systematic processes were in place. They participated in CR to the same high degree as their nonsystematically referred counterparts. These referral strategies should be implemented to promote equitable access.

Development and feasibility of a smartphone, ECG and GPS based system for remotely monitoring exercise in cardiac rehabilitation

BACKGROUND

Despite its efficacy and cost-effectiveness, exercise-based cardiac rehabilitation is undertaken by less than one-third of clinically eligible cardiac patients in every country for which data is available. Reasons for non-participation include the unavailability of hospital-based rehabilitation programs, or excessive travel time and distance. For this reason, there have been calls for the development of more flexible alternatives.

METHODOLOGY AND PRINCIPAL FINDINGS

We developed a system to enable walking-based cardiac rehabilitation in which the patient's single-lead ECG, heart rate, GPS-based speed and location are transmitted by a programmed smartphone to a secure server for real-time monitoring by a qualified exercise scientist. The feasibility of this approach was evaluated in 134 remotely-monitored exercise assessment and exercise sessions in cardiac patients unable to undertake hospital-based rehabilitation. Completion rates, rates of technical problems, detection of ECG changes, pre- and post-intervention six minute walk test (6 MWT), cardiac depression and Quality of Life (QOL) were key measures. The system was rated as easy and quick to use. It allowed participants to complete six weeks of exercise-based rehabilitation near their homes, worksites, or when travelling. The majority of sessions were completed without any technical problems, although periodic signal loss in areas of poor coverage was an occasional limitation. Several exercise and post-exercise ECG changes were detected. Participants showed improvements comparable to those reported for hospital-based programs, walking significantly further on the post-intervention 6 MWT, 637 m (95% CI: 565-726), than on the pre-test, 524 m (95% CI: 420-655), and reporting significantly reduced levels of cardiac depression and significantly improved physical health-related QOL.

CONCLUSIONS AND SIGNIFICANCE

The system provided a feasible and very flexible alternative form of supervised cardiac rehabilitation for those unable to access hospital-based programs, with the potential to address a well-recognised deficiency in health care provision in many countries. Future research should assess its longer-term efficacy, cost-effectiveness and safety in larger samples representing the spectrum of cardiac morbidity and severity.

Geographic issues in cardiac rehabilitation utilization: a narrative review

OBJECTIVE

The purpose of this study was to review the current evidence regarding the relationship between geographic indicators and cardiac rehabilitation (CR) utilization among coronary heart disease (CHD) patients.

RESULTS

Seventeen articles were identified for inclusion, where nine studies assessed rurality, 10 studies assessed travel time/distance, and two of these studies assessed both. Nine of the 17 studies (52.9%) showed a significant negative relationship between geographic barrier and CR use. Four of the 17 studies (23.5%) showed a null relationship, while four studies (23.5%) showed mixed findings. Inconsistent findings identified appeared to be related to restricted geographic range, regional density, and socioeconomic status.

CONCLUSIONS

Overall, 52.9% of the identified studies reported a significant negative relationship between geographic indicators and CR utilization. This relationship appeared to be particularly consistent in North American and Australian settings, but somewhat less so in the United Kingdom where there is greater population density and availability of public transport.

Effects of cardiac rehabilitation referral strategies on referral and enrollment rates

Despite recommendations in clinical practice guidelines, evidence suggests that utilization of cardiac rehabilitation (CR) following indicated cardiac events is low. Referral strategies, such as automatic referral, have been advocated to improve CR utilization. In this Review, we evaluate the effects of referral strategies on rates of CR referral and enrollment. Referral strategies are categorized as 'automatic' (the use of electronic health records or systematic discharge order sets), as 'liaison' (discussions with allied health-care providers), or as 'other' (for example, the use of motivational letter to patients). The highest rates of CR referral have been achieved in studies implementing automatic referral orders, whereas the highest rates of CR enrollment have resulted from a combination of automatic and liaison methods. Overall, innovative referral strategies significantly increase CR utilization. While further investigation is needed, institutions should evaluate their CR referral practice in light of these findings.
