Patient education and quality of home-based rehabilitation in patients older than 60 years after acute myocardial infarction

What is the effect of a brief intervention to promote physical activity when delivered in a health care setting? A systematic review

ISSUE ADDRESSED

What are the effects of a brief intervention to promote physical activity (PA) delivered in a health care setting other than primary care?

METHODS

MEDLINE, EMBASE, CINAHL and PsycINFO were used to identify randomised controlled trials which evaluated the effect of brief interventions to increase PA, delivered in a health care setting. Review outcomes included subjectively or objectively measured PA, adherence to prescribed interventions, adverse events, health-related quality of life, self-efficacy and stage of change in relation to PA. Where possible, clinically homogenous studies were combined in a meta-analysis.

RESULTS

Twenty-five eligible papers were included. Brief counselling interventions were associated with increased PA compared to control, for both self-reported PA (mean difference 34 minutes/week, 95% confidence intervals [95% CI] 9-60 minutes), and pedometer (MD 1541 steps/day, 95% CI 433-2649) at medium term follow up.

CONCLUSION

Our findings suggest that some brief interventions to increase PA, delivered in the health care setting, are effective at increasing PA in the medium term. There is limited evidence for the long-term efficacy of such interventions. The wide variation in types of interventions makes it difficult to determine which intervention features optimize outcomes. SO WHAT?: Brief counselling interventions delivered in a health care setting may support improved PA. Clinicians working in health care settings should consider the implementation of brief interventions to increase PA in vulnerable patient groups, including older adults and those with chronic illness.

Promotion and maintenance of physically active lifestyle in older outpatients 2 years after acute coronary syndrome

AIMS

To examine long-term changes in lifestyle and exercise capacity of older patients hospitalized for acute coronary syndrome (ACS) involved in an innovative centre- and home-based exercise-based secondary prevention program.

METHODS

A sample of 118 patients with ACS (age 76 [72-80] years) was analysed. Long-term changes in self-reported weekly leisure-time physical activity (wLTPA), walking speed (WS), and estimated cardiorespiratory fitness (eCRF, VO₂peak, mL/kg/min) were the outcome variables. The program consisted of seven individual on-site sessions including motivational interviewing to reach exercise goals. Exercise prescription was based on the results of a standardized moderate and perceptually regulated treadmill walk to estimate VO₂peak. wLTPA, WS, and eCRF were assessed at 1 (baseline), 2, 3, 4, 6, 12, and 24 months after discharge.

RESULTS

87, 76, and 70 patients completed follow-up at 6, 12, and 24 months, respectively. wLTPA significantly increased during the follow-up period (median METs/H/week 2.5, 11.2, 12.0, and 13.4 at baseline, 6, 12, and 24 months, respectively; P < 0.0001). At baseline, 18% of the sample met the current international guidelines for physical activity, while 75%, 70%, and 76% of them met the recommended values at 6-, 12-, and 24-month follow-up sessions, respectively. These results were associated with increasing median WS (2.9 ± 1.0, 4.3 ± 1.2, 4.5 ± 1.1, 4.5 ± 1.2 km/h, respectively, P < 0.0001), and VO₂peak (16.5, 21.4, 21.1, 21.3 mL/kg/min, respectively, P < 0.0001).

CONCLUSIONS

This early, individualized exercise intervention improved long-term adherence to a physically active lifestyle, walking capacity, and eCRF in older patients after ACS. Larger studies are needed to confirm short- and long-term clinical benefits of this intervention.

A Brief Intervention of Physical Activity Education and Counseling in Community Rehabilitation: A Feasibility Randomized Controlled Trial

This study aimed to assess the feasibility of delivering a brief physical activity (PA) intervention to community rehabilitation clients. Participants were randomized to receive one session of stage-of-change-based PA education and counseling in addition to written educational material, or education material alone. Outcomes were measured at baseline and 3 months; the primary outcome was feasibility, measured by the percentage of those who were eligible, consented, randomized, and followed-up. A total of 123 individuals were both eligible and interested in participating, 32% of those screened on admission to the program. Forty participants consented, and 35 were randomized, with mean age 72 years (SD = 12.2). At baseline, 66% had recently commenced or intended to begin regular PA in the next 6 months. A total of 30 participants were followed-up. It is feasible to deliver education and counseling designed to support the long-term adoption of regular PA to community rehabilitation clients. Further refinement of the protocol is warranted (ACTRN12617000519358).

Community-Based Physical Rehabilitation After Percutaneous Coronary Intervention for Acute Myocardial Infarction

To determine whether a community-based physical rehabilitation program could improve the prognosis of patients who had undergone percutaneous coronary intervention after acute myocardial infarction, we randomly divided 164 consecutive patients into 2 groups of 82 patients. Patients in the rehabilitation group underwent 3 months of supervised exercise training, then 9 months of community-based, self-managed exercise; patients in the control group received conventional treatment. The primary endpoint was major adverse cardiac events (MACE) during the follow-up period (25 ± 15.4 mo); secondary endpoints included left ventricular ejection fraction, 6-minute walk distance, and laboratory values at 12-month follow-up. During the study period, the incidence of MACE was significantly lower in the rehabilitation group (13.4% vs 24.4%; P <0.01). Cox proportional hazards regression analysis indicated a significantly lower risk of MACE in the rehabilitation group (hazard ratio=0.56; 95% CI, 0.37-0.82; P=0.01). At 12 months, left ventricular ejection fraction and 6-minute walk distance in the rehabilitation group were significantly greater than those in the control group (both P <0.01), and laboratory values also improved. These findings suggest that community-based physical rehabilitation significantly reduced MACE risk and improved cardiac function and physical stamina in patients who underwent percutaneous coronary intervention after acute myocardial infarction.

Patients' Use of Social Media for Diabetes Self-Care: Systematic Review

BACKGROUND

Patient engagement with diabetes self-care is critical to reducing morbidity and mortality. Social media is one form of digital health that is available for diabetes self-care, although its use for peer-to-peer communication has not been systematically described, and its potential to support patient self-care is unclear.

OBJECTIVE

The primary aim of this systematic review was to describe the use of social media among patients (peer-to-peer) to manage diabetes and cardiovascular disease (CVD). The secondary aim was to assess patients' clinical outcomes, behavioral outcomes, quality of life, and self-efficacy resulting from peer-to-peer social media use.

METHODS

We conducted a literature search in the following databases: PubMed, EMBASE, Web of Science, CINAHL, and PsycINFO (January 2008 through April 2019). The inclusion criteria were quantitative studies that included peer-to-peer use of social media for self-care of diabetes mellitus (with all subtypes) and CVD, including stroke.

RESULTS

After an initial yield of 3066 citations, we selected 91 articles for a full-text review and identified 7 papers that met our inclusion criteria. Of these, 4 studies focused on type 1 diabetes, 1 study included both type 1 and 2 diabetes, and 2 studies included multiple chronic conditions (eg, CVD, diabetes, depression, etc). Our search did not yield any individual studies on CVD alone. Among the selected papers, 2 studies used commercial platforms (Facebook and I Seek You), 3 studies used discussion forums developed specifically for each study, and 2 surveyed patients through different platforms or blogs. There was significant heterogeneity in the study designs, methodologies, and outcomes applied, but all studies showed favorable results on either primary or secondary outcomes. The quality of studies was highly variable.

CONCLUSIONS

The future landscape of social media use for patient self-care is promising. However, current use is nascent. Our extensive search yielded only 7 studies, all of which included diabetes, indicating the most interest and demand for peer-to-peer interaction on diabetes self-care. Future research is needed to establish efficacy and safety in recommending social media use among peers for diabetes self-care and other conditions.

Impact of cardiac rehabilitation programs on left ventricular remodeling after acute myocardial infarction: Study Protocol Clinical Trial (SPIRIT Compliant)

INTRODUCTION

While the role of early mobilization in the immediate postinfarction period has been well demonstrated, little is known in present about the link between early mobilization and reduction of systemic inflammation. At the same time, the impact of early mobilization on regression of left ventricular remodeling has not been elucidated so far.

MATERIAL AND METHODS

Here we present the study protocol of the REHAB trial, a clinical descriptive, prospective study, conducted in a single-center, with the purpose to analyze the impact of early mobilization in reducing left ventricular remodeling, the complication rates and mortality in patients who had suffered a recent acute myocardial infarction (AMI). At the same time, the study aims to demonstrate the contribution of early mobilization to reduction of systemic inflammation, thus reducing the inflammation-mediated ventricular remodeling. 100 patients with AMI in the last 12 hours, and successful revascularization of the culprit artery within the first 12 hours after the onset of symptoms in ST-segment elevation acute myocardial infarction or within first 48 hours in non ST-segment elevation AMI will be enrolled in the study. Based on the moment of mobilization after AMI patients will be distributed in 2 groups: group 1 - patients with early mobilization (<2 days after the onset of symptoms) and; group 2 - subjects with delayed mobilization after AMI (>2 days after the onset of symptoms). Study outcomes will consist in the impact of early mobilization after AMI on the ventricular remodeling in the post-infarction period, as assessed by cardiac magnetic resonance imaging, the rate of in-hospital mortality, the rate of repeated revascularization or MACE and the effect of early mobilization on systemic inflammation in the immediate postinfarction phase.

CONCLUSION

In conclusion, REHAB will be the first trial that will elucidate the impact of early mobilization in the first period after AMI, as a first step of a complex cardiac rehabilitation program, to reduce systemic inflammation and prevent deleterious ventricular remodeling in patients who suffered a recent AMI.

[Modern strategies for cardiac rehabilitation after myocardial infarction and percutaneous coronary intervention]

Modern cardiac rehabilitation represents a structured, multicomponent program, which includes physical activity, education of the patient, modification of the health behavior, and psychological and social support. In EU countries, only 44.8% of patients with ischemic heart disease receive a recommendation to participate in any form of rehabilitation, and only 36.5% of all patients presently have an access to any rehabilitation program. Systematic analysis of programs for prevention of cardiovascular diseases and for rehabilitation in patients with myocardial infarction (MI) and percutaneous coronary intervention showed that complex programs can still reduce all-cause and cardiovascular mortality and frequency of recurrent MI and stroke. These programs include key components of cardiac rehabilitation, reduction of six or more risk factors, and effective control by drug therapy.

Differential prognostic impact between completion and non-completion of a 5-month cardiac rehabilitation program in outpatients with cardiovascular diseases

BACKGROUND

Cardiac rehabilitation (CR) is an essential component of care for patients with cardiovascular diseases (CVD). We aimed to evaluate clinical outcomes in outpatients with CVD who did and did not complete a 5-month CR program.

METHODS

Three hundred thirty-two outpatients with CVD who participated in a 5-month CR program and were followed-up for maximum 5 years were registered. We divided the patients into two groups: those who completed the CR program (success group, n = 175) and those who could not (non-success group, n = 157). Both long-term (5 years) and short-term (5 months) clinical outcomes were compared between the two groups.

RESULTS

There were no significant differences in patient characteristics at baseline between the success and non-success groups. With regard to both long-term and short-term clinical outcomes, the rates of all-cause death and hospital admission in the success group were significantly lower than those in the non-success group by a Kaplan-Meier analysis. There was a significant difference in short-term CVD death and hospital admission between the groups, but not for long-term CVD death and hospital. In long-term period, all-cause death and hospital admission was independently associated with completion of the CR program in addition to the presence of peripheral artery disease and VE vs. VCO₂ slope after adjusting for age, gender, body mass index, types of CVD and medications.

CONCLUSIONS

Completion of a 5-month CR program was associated with the prevention of all-cause death and hospital admission, but not CVD death and hospital admission in the long-term, which suggests that we need to reconsider this issue.

The effect of community-based interventions for cardiovascular disease secondary prevention on behavioural risk factors

Cardiovascular disease (CVD) is the leading cause of death worldwide, and its prevalence is increasing; with limited healthcare resources, secondary prevention programmes outside traditional hospital settings are needed, but their effectiveness is unclear. We aimed to assess the effectiveness of secondary prevention cardiovascular risk reduction programmes delivered in venues situated within the community on modification of behavioural risk factors. We searched five databases (MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane library) to identify trials of health behaviour interventions for adults with CVD in community-based venues. Primary outcomes were changes in physical activity, diet, smoking and/or alcohol consumption. Two reviewers independently assessed articles for eligibility and risk of bias; statistical analysis used Revman v5.3. Of 5905 articles identified, 41 articles (38 studies) (n = 7970) were included. Interventions were mainly multifactorial, educational, psychological and physical activity-based. Meta-analyses identified increased steps/week (Mean Difference (MD): 7480; 95% CI 1,940, 13,020) and minutes of physical activity/week (MD: 59.96; 95% CI 15.67, 104.25) associated with interventions. There was some evidence for beneficial effects on peak VO₂, blood pressure, total cholesterol and mental health. Variation in outcome measurements reported for other behavioural risk factors limited our ability to perform meta-analyses. Effective interventions were based in homes, general practices or outpatient settings, individually tailored and often multicomponent with a theoretical framework. Our review identified evidence that interventions for secondary CVD prevention, delivered in various community-based venues, have positive effects on physical activity; such opportunities should be promoted by health professionals.

Long-term Physical Activity Behavior After Completion of Traditional Versus Fast-track Cardiac Rehabilitation

BACKGROUND

Despite the health benefits associated with regular physical activity (PA), many cardiac patients fail to maintain optimal levels of PA after completing cardiac rehabilitation (CR). The long-term impact of different CR delivery models on the PA habits of cardiac patients is not completely understood.

OBJECTIVE

The purpose of this study is to use a multisensor accelerometer to compare the long-term impact of a traditional versus fast-track CR on the PA of patients with coronary artery disease 6 months after CR entry.

METHODS

Forty-four participants attended either traditional (twice a week, 12 weeks; n = 24) or fast-track (once a week, 8 weeks; n = 20) CR. Exercise capacity (ie, 6-minute walk test distance) and PA were assessed at baseline and at 12 weeks and 6 months after CR entry.

RESULTS

At 12 weeks, exercise capacity increased significantly in both groups and remained elevated by the 6-month follow-up. Sedentary time decreased from baseline to 12 weeks. However, at 6 months, it was comparable with the baseline level. There was no significant change in any other PA marker (ie, steps/day, time in light and moderate-vigorous PA) over the course of the study.

CONCLUSIONS

Findings support the long-term effectiveness of CR on exercise capacity irrespective of the delivery model. However, participation in CR program, whether it be a traditional or fast-track CR exercise program, may not lead to long-term PA behavior change. Thus, CR participants may benefit from structured strategies that promote long-term PA adherence in addition to facilitating exercise capacity improvement.

Cardiac rehabilitation in acute myocardial infarction patients after percutaneous coronary intervention: A community-based study

BACKGROUND

Acute myocardial infarction (AMI) is one of the leading causes of death and physical disability worldwide. However, the development of community- based cardiac rehabilitation (CR) in AMI patients is hysteretic. Here, we aimed to evaluate the safety and efficacy of CR applied in the community in AMI patients who underwent percutaneous coronary intervention (PCI).

METHODS

A total of 130 ST-segment elevated myocardial infarction (STEMI) patients after PCI were randomly divided into 2 groups in the community, rehabilitation group (n = 65) and control group (n = 65). Cardiac function, a 6-minute walk distance, exercise time and steps, cardiovascular risk factors were monitored respectively and compared before and after the intervention of 2 groups. The software of EpiData 3.1 was used to input research data and SPSS16.0 was used for statistical analysis.

RESULTS

After a planned rehabilitation intervention, the rehabilitation group showed better results than the control group. The rehabilitation group had a significant improvement in recurrence angina and readmission (P < .01). Left ventricular ejection fraction (LVEF) of rehabilitation group showed improvement in phase II (t = 4.963, P < .01) and phase III (t = 11.802, P < .01), and the New York Heart Association (NYHA) classification was recovered within class II. There was a significant difference compared with before (Z = 7.238, P < .01). Six minutes walking distance, aerobic exercise time, and steps all achieved rehabilitation requirements in rehabilitation group in phase II and III, there existed distinct variation between 2 phases. Rehabilitation group had a better result in cardiovascular risk factors than control group (P < .05).

CONCLUSION

Community-based CR after PCI through simple but safe exercise methods can improve the AMI patient's living quality, which includes increasing cardiac ejection fraction, exercise tolerance, and physical status. It must be emphasized that the good result should be established by the foundation of close cooperation between cardiologists and general practitioners, also the importance of cooperation of patients and their families should not be ignored. The rehabilitation program we used is feasible, safe, and effective.

Home-based versus centre-based cardiac rehabilitation

BACKGROUND

Cardiovascular disease is the most common cause of death globally. Traditionally, centre-based cardiac rehabilitation programmes are offered to individuals after cardiac events to aid recovery and prevent further cardiac illness. Home-based cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation. This is an update of a review previously published in 2009 and 2015.

OBJECTIVES

To compare the effect of home-based and supervised centre-based cardiac rehabilitation on mortality and morbidity, exercise-capacity, health-related quality of life, and modifiable cardiac risk factors in patients with heart disease.

SEARCH METHODS

We updated searches from the previous Cochrane Review by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) on 21 September 2016. We also searched two clinical trials registers as well as previous systematic reviews and reference lists of included studies. No language restrictions were applied.

SELECTION CRITERIA

We included randomised controlled trials, including parallel group, cross-over or quasi-randomised designs) that compared centre-based cardiac rehabilitation (e.g. hospital, gymnasium, sports centre) with home-based programmes in adults with myocardial infarction, angina, heart failure or who had undergone revascularisation.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all identified references for inclusion based on pre-defined inclusion criteria. Disagreements were resolved through discussion or by involving a third review author. Two authors independently extracted outcome data and study characteristics and assessed risk of bias. Quality of evidence was assessed using GRADE principles and a Summary of findings table was created.

MAIN RESULTS

We included six new studies (624 participants) for this update, which now includes a total of 23 trials that randomised a total of 2890 participants undergoing cardiac rehabilitation. Participants had an acute myocardial infarction, revascularisation or heart failure. A number of studies provided insufficient detail to enable assessment of potential risk of bias, in particular, details of generation and concealment of random allocation sequencing and blinding of outcome assessment were poorly reported.No evidence of a difference was seen between home- and centre-based cardiac rehabilitation in clinical primary outcomes up to 12 months of follow up: total mortality (relative risk (RR) = 1.19, 95% CI 0.65 to 2.16; participants = 1505; studies = 11/comparisons = 13; very low quality evidence), exercise capacity (standardised mean difference (SMD) = -0.13, 95% CI -0.28 to 0.02; participants = 2255; studies = 22/comparisons = 26; low quality evidence), or health-related quality of life up to 24 months (not estimable). Trials were generally of short duration, with only three studies reporting outcomes beyond 12 months (exercise capacity: SMD 0.11, 95% CI -0.01 to 0.23; participants = 1074; studies = 3; moderate quality evidence). However, there was evidence of marginally higher levels of programme completion (RR 1.04, 95% CI 1.00 to 1.08; participants = 2615; studies = 22/comparisons = 26; low quality evidence) by home-based participants.

AUTHORS' CONCLUSIONS

This update supports previous conclusions that home- and centre-based forms of cardiac rehabilitation seem to be similarly effective in improving clinical and health-related quality of life outcomes in patients after myocardial infarction or revascularisation, or with heart failure. This finding supports the continued expansion of evidence-based, home-based cardiac rehabilitation programmes. The choice of participating in a more traditional and supervised centre-based programme or a home-based programme may reflect local availability and consider the preference of the individual patient. Further data are needed to determine whether the effects of home- and centre-based cardiac rehabilitation reported in the included short-term trials can be confirmed in the longer term and need to consider adequately powered non-inferiority or equivalence study designs.

Patient education in the management of coronary heart disease

BACKGROUND

Coronary heart disease (CHD) is the single most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people live with CHD and may need support to manage their symptoms and improve prognosis. Cardiac rehabilitation is a complex multifaceted intervention which aims to improve the health outcomes of people with CHD. Cardiac rehabilitation consists of three core modalities: education, exercise training and psychological support. This is an update of a Cochrane systematic review previously published in 2011, which aims to investigate the specific impact of the educational component of cardiac rehabilitation.

OBJECTIVES

1. To assess the effects of patient education delivered as part of cardiac rehabilitation, compared with usual care on mortality, morbidity, health-related quality of life (HRQoL) and healthcare costs in patients with CHD.2. To explore the potential study level predictors of the effects of patient education in patients with CHD (e.g. individual versus group intervention, timing with respect to index cardiac event).

SEARCH METHODS

We updated searches from the previous Cochrane review, by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library, Issue 6, 2016), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) in June 2016. Three trials registries, previous systematic reviews and reference lists of included studies were also searched. No language restrictions were applied.

SELECTION CRITERIA

1. Randomised controlled trials (RCTs) where the primary interventional intent was education delivered as part of cardiac rehabilitation.2. Studies with a minimum of six-months follow-up and published in 1990 or later.3. Adults with a diagnosis of CHD.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened all identified references for inclusion based on the above inclusion criteria. One author extracted study characteristics from the included trials and assessed their risk of bias; a second review author checked data. Two independent reviewers extracted outcome data onto a standardised collection form. For dichotomous variables, risk ratios and 95% confidence intervals (CI) were derived for each outcome. Heterogeneity amongst included studies was explored qualitatively and quantitatively. Where appropriate and possible, results from included studies were combined for each outcome to give an overall estimate of treatment effect. Given the degree of clinical heterogeneity seen in participant selection, interventions and comparators across studies, we decided it was appropriate to pool studies using random-effects modelling. We planned to undertake subgroup analysis and stratified meta-analysis, sensitivity analysis and meta-regression to examine potential treatment effect modifiers. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to evaluate the quality of the evidence and the GRADE profiler (GRADEpro GDT) to create summary of findings tables.

MAIN RESULTS

This updated review included a total of 22 trials which randomised 76,864 people with CHD to an education intervention or a 'no education' comparator. Nine new trials (8215 people) were included for this update. We judged most included studies as low risk of bias across most domains. Educational 'dose' ranged from one 40 minute face-to-face session plus a 15 minute follow-up call, to a four-week residential stay with 11 months of follow-up sessions. Control groups received usual medical care, typically consisting of referral to an outpatient cardiologist, primary care physician, or both.We found evidence of no difference in effect of education-based interventions on total mortality (13 studies, 10,075 participants; 189/5187 (3.6%) versus 222/4888 (4.6%); random effects risk ratio (RR) 0.80, 95% CI 0.60 to 1.05; moderate quality evidence). Individual causes of mortality were reported rarely, and we were unable to report separate results for cardiovascular mortality or non-cardiovascular mortality. There was evidence of no difference in effect of education-based interventions on fatal and/or non fatal myocardial infarction (MI) (2 studies, 209 participants; 7/107 (6.5%) versus 12/102 (11.8%); random effects RR 0.63, 95% CI 0.26 to 1.48; very low quality of evidence). However, there was some evidence of a reduction with education in fatal and/or non-fatal cardiovascular events (2 studies, 310 studies; 21/152 (13.8%) versus 61/158 (38.6%); random effects RR 0.36, 95% CI 0.23 to 0.56; low quality evidence). There was evidence of no difference in effect of education on the rate of total revascularisations (3 studies, 456 participants; 5/228 (2.2%) versus 8/228 (3.5%); random effects RR 0.58, 95% CI 0.19 to 1.71; very low quality evidence) or hospitalisations (5 studies, 14,849 participants; 656/10048 (6.5%) versus 381/4801 (7.9%); random effects RR 0.93, 95% CI 0.71 to 1.21; very low quality evidence). There was evidence of no difference between groups for all cause withdrawal (17 studies, 10,972 participants; 525/5632 (9.3%) versus 493/5340 (9.2%); random effects RR 1.04, 95% CI 0.88 to 1.22; low quality evidence). Although some health-related quality of life (HRQoL) domain scores were higher with education, there was no consistent evidence of superiority across all domains.

AUTHORS' CONCLUSIONS

We found no reduction in total mortality, in people who received education delivered as part of cardiac rehabilitation, compared to people in control groups (moderate quality evidence). There were no improvements in fatal or non fatal MI, total revascularisations or hospitalisations, with education. There was some evidence of a reduction in fatal and/or non-fatal cardiovascular events with education, but this was based on only two studies. There was also some evidence to suggest that education-based interventions may improve HRQoL. Our findings are supportive of current national and international clinical guidelines that cardiac rehabilitation for people with CHD should be comprehensive and include educational interventions together with exercise and psychological therapy. Further definitive research into education interventions for people with CHD is needed.

Promoting patient uptake and adherence in cardiac rehabilitation

BACKGROUND

Cardiac rehabilitation is an important component of recovery from coronary events but uptake and adherence to such programs are below recommended levels. In 2010, our Cochrane review identified some evidence that interventions to increase uptake of cardiac rehabilitation can be effective but there was insufficient evidence to provide recommendations on intervention to increase adherence. In this review, we update the previously published Cochrane review.

OBJECTIVES

To determine the effects, both harms and benefits, of interventions to increase patient uptake of, or adherence to, cardiac rehabilitation.

SEARCH METHODS

We performed an updated search in January 2013 to identify studies published after publication of the previous systematic review. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 12, 2012), MEDLINE (Ovid), EMBASE (Ovid), CINAHL EBSCO, Conference Proceedings Citation Index - Science (CPCI-S) on Web of Science (Thomson Reuters), and National Health Service (NHS) Centre for Reviews and Dissemination (CRD) databases (Health Technology Assessment (HTA) and Database of Abstracts of Reviews of Effects (DARE)) on The Cochrane Library (Issue 4, 2012). We also checked reference lists of identified systematic reviews and randomised controlled trials (RCTs) for additional studies. We applied no language restrictions.

SELECTION CRITERIA

Adults with myocardial infarction, coronary artery bypass graft, percutaneous transluminal coronary angioplasty, heart failure, angina, or coronary heart disease eligible for cardiac rehabilitation and RCTs or quasi-randomized trials of interventions to increase uptake or adherence to cardiac rehabilitation or any of its component parts. We only included studies reporting a primary outcome.

DATA COLLECTION AND ANALYSIS

At least three authors independently screened titles and abstracts of all identified references for eligibility and obtained full papers of potentially relevant trials. At least two authors checked the selection. Three authors assessed included studies for risk of bias.

MAIN RESULTS

The updated search identified seven new studies (880 participants) of interventions to improve uptake of cardiac rehabilitation and one new study (260 participants) of interventions to increase adherence. When added to the previous version of this review, we included 18 studies (2505 participants), 10 studies (1338 participants) of interventions to improve uptake of cardiac rehabilitation and eight studies (1167 participants) of interventions to increase adherence. We assessed the majority of studies as having high or unclear risk of bias. Meta-analysis was not possible due to multiple sources of heterogeneity. Eight of 10 studies demonstrated increased uptake of cardiac rehabilitation. Successful interventions to improve uptake of cardiac rehabilitation included: structured nurse- or therapist-led contacts, early appointments after discharge, motivational letters, gender-specific programs, and intermediate phase programs for older patients. Three of eight studies demonstrated improvement in adherence to cardiac rehabilitation. Successful interventions included: self monitoring of activity, action planning, and tailored counselling by cardiac rehabilitation staff. Data were limited on mortality and morbidity but did not demonstrate a difference in cardiovascular events or mortality except for one study that noted an increased rate of revascularization in the intervention group. None of the studies found a difference in health-related quality of life and there was no evidence of adverse events. No studies reported on costs or healthcare utilization.

AUTHORS' CONCLUSIONS

We found only weak evidence to suggest that interventions to increase the uptake of cardiac rehabilitation are effective. Practice recommendations for increasing adherence to cardiac rehabilitation cannot be made. Interventions targeting patient-identified barriers may increase the likelihood of success. Further high-quality research is still needed. 

A systematic review of patient education in cardiac patients: do they increase knowledge and promote health behavior change?

OBJECTIVE

(1) To investigate the impact of education on patients' knowledge; (2) to determine if educational interventions are related to health behavior change in cardiac patients; and (3) to describe the nature of educational interventions.

METHODS

A literature search of several electronic databases was conducted for published articles from database inception to August 2012. Eligible articles included cardiac patients, and described delivery of educational interventions by a healthcare provider. Outcomes were knowledge, smoking, physical activity, dietary habits, response to symptoms, medication adherence, and psychosocial well-being. Articles were reviewed by 2 authors independently.

RESULTS

Overall, 42 articles were included, of which 23 (55%) were randomized controlled trials, and 16 (38%) were considered "good" quality. Eleven studies (26%) assessed knowledge, and 10 showed a significant increase with education. With regard to outcomes, educational interventions were significantly and positively related to physical activity, dietary habits, and smoking cessation. The nature of interventions was poorly described and most frequently delivered post-discharge, by a nurse, and in groups.

CONCLUSIONS

Findings support the benefits of educational interventions in CHD, though increase in patients' knowledge and behavior change.

PRACTICE IMPLICATIONS

Future reporting of education interventions should be more explicitly characterized, in order to be reproducible and assessed.

Alternative models of cardiac rehabilitation: a systematic review

The traditional hospital-based model of cardiac rehabilitation faces substantial challenges, such as cost and accessibility. These challenges have led to the development of alternative models of cardiac rehabilitation in recent years. The aim of this study was to identify and critique evidence for the effectiveness of these alternative models. A total of 22 databases were searched to identify quantitative studies or systematic reviews of quantitative studies regarding the effectiveness of alternative models of cardiac rehabilitation. Included studies were appraised using a Critical Appraisal Skills Programme tool and the National Health and Medical Research Council's designations for Level of Evidence. The 83 included articles described interventions in the following broad categories of alternative models of care: multifactorial individualized telehealth, internet based, telehealth focused on exercise, telehealth focused on recovery, community- or home-based, and complementary therapies. Multifactorial individualized telehealth and community- or home-based cardiac rehabilitation are effective alternative models of cardiac rehabilitation, as they have produced similar reductions in cardiovascular disease risk factors compared with hospital-based programmes. While further research is required to address the paucity of data available regarding the effectiveness of alternative models of cardiac rehabilitation in rural, remote, and culturally and linguistically diverse populations, our review indicates there is no need to rely on hospital-based strategies alone to deliver effective cardiac rehabilitation. Local healthcare systems should strive to integrate alternative models of cardiac rehabilitation, such as brief telehealth interventions tailored to individual's risk factor profiles as well as community- or home-based programmes, in order to ensure there are choices available for patients that best fit their needs, risk factor profile, and preferences.
