Exercise-based cardiac rehabilitation after acute myocardial infarction in Sweden - standards, costs, and adherence to European guidelines (The Perfect-CR study)

AIMS

Information on standards including structure- and process-based metrics and how exercise-based cardiac rehabilitation (EBCR) is delivered in relation to guidelines is lacking. The aims of the study were to evaluate standards and adherence to guidelines at Swedish CR centers and to conduct a cost analysis of the physiotherapy-related activities of EBCR.

METHODS AND RESULTS

EBCR standards at all 78 CR centers in Sweden in 2016 were surveyed. The questions were based on guideline-recommended core components of EBCR for patients after a myocardial infarction (MI). The cost analysis included the identification, quantification, and valuation of EBCR-related cost items. Patients were offered a pre-discharge consultation with a physiotherapist at n = 61, 78% of the centers. A pre-exercise screening visit was routinely offered at n = 64, 82% of the centers, at which a test of aerobic capacity was offered in n = 58, 91% of cases, most often as a cycle ergometer exercise test n = 55, 86%. A post-exercise assessment was offered at n = 44, 56% of the centers, with a functional test performed at n = 30, 68%. Almost all the centers n = 76, 97% offered supervised EBCR programs. The total cost of delivering physiotherapy-related activities of EBCR according to guidelines was approximately 437 euro (4,371 SEK) per patient. Delivering EBCR to one MI patient required 11.25 hours of physiotherapy time.

CONCLUSION

While the overall quality of EBCR programs in Sweden is high, there are several areas of potential improvement to reach the recommended European standards across all centers. To improve the quality of EBCR, further compliance with guidelines is warranted.

Factors associated with participation in cardiac rehabilitation in patients with acute myocardial infarction: A systematic review and meta-analysis

BACKGROUND

Cardiac rehabilitation (CR) is effective in reducing morbidity and mortality in patients with acute myocardial infarction (AMI), but the participation rate is low and its influencing factors vary. Our study aimed to systematically review the literature and investigate the participation rates and influencing factors of CR in patients with AMI.

METHODS

We searched 10 databases, including PubMed, Web of Science, Cochrane Library, and so forth. A systematic review and meta-analysis were conducted on the studies on the factors affecting CR participation in AMI. The Q tests and the I2 tests were used to assess heterogeneity between studies. The combined effect size and odds ratio (OR) and their respective 95% confidence interval (CI) for CR participation rate and its influences are expressed, respectively. Stata 17.0 software was used for statistical analysis.

RESULTS

We included 14 studies with 114 542 participants. Current evidence indicates a CR participation rate of 34% (95% CI: 21%-46%) in patients with AMI. The pooled OR values and CI of each influencing factor are as follows: over 60 years old (OR = 0.865; 95% CI: 0.772-0.969), male (OR = 1.690; 95% CI: 1.276-2.239), college education or above (OR = 2.526; 95% CI: 1.117-5.711), ST-segment elevation myocardial infarction (OR = 4.257; 95% CI: 2.004-9.045), decrease in left ventricular ejection fraction (OR = 0.918; 95% CI: 0.868-0.971), higher economic level (OR = 1.282; 95% CI: 1.108-1.483), history of coronary heart disease(OR = 0.667; 95% CI: 0.509-0.875), smoking (OR = 0.665; 95% CI: 0.550-0.805), combined hypertension (OR = 0.638; 95% CI: 0.562-0.723), and combined hyperlipidemia (OR = 0.577; 95% CI: 0.512-0.651).

CONCLUSIONS

The overall participation rate of CR in AMI patients is low, and various factors affect the participation rate. Specialist medical staff are needed to further promote CR rehabilitation concepts and scientific knowledge, and take appropriate measures to address the influencing factors to increase CR utilization and improve patient prognosis.

A National Survey of Patient Data Capture, Management, Reporting Practice in Australian Cardiac Rehabilitation Programs

BACKGROUND

Lack of service data for cardiac rehabilitation limits understanding of program delivery, benchmarking and quality improvement. This study aimed to describe current practices, management, utilisation and engagement with quality indicators in Australian programs.

METHOD

Cardiac rehabilitation programs (n=396) were identified from national directories and networks. Program coordinators were surveyed on service data capture, management systems and adoption of published national quality indicators. Text responses were coded and classified. Logistic regression determined independent associates of the use of data for quality improvement.

RESULTS

A total of 319 (81%) coordinators completed the survey. Annual patient enrolments/programs were >200 (31.0%), 51-200 (46%) and ≤50 (23%). Most (79%) programs used an electronic system, alongside paper (63%) and/or another electronic system (19%), with 21% completely paper. While 84% knew of the national quality indicators, only 52% used them. Supplementary to patient care, data were used for reports to managers (57%) and funders (41%), to improve quality (56%), support funding (43%) and research (31%). Using data for quality improvement was more likely when enrolments where >200 (Odds ratio [OR] 3.83, 95% Confidence Interval [CI] 1.76-8.34) and less likely in Victoria (OR 0.24 95%, CI 0.08-0.77), New South Wales (OR 0.25 95%, CI 0.08-0.76) and Western Australia (OR 0.16 95%, CI 0.05-0.57).

CONCLUSIONS

The collection of service data for cardiac rehabilitation patient data and its justification is diverse, limiting our capacity to benchmark and drive clinical practice. The findings strengthen the case for a national low-burden approach to data capture for quality care.

Assessment of activities and participation of people by rehabilitation-focused clinical registries: a systematic scoping review

INTRODUCTION

Rehabilitation is considered a key intervention in health care. Clinical registries, defined as an organized system that uses observational methods to collect information to assess specific outcomes in a defined population, can contribute to assessing the impact of the rehabilitation intervention. This review aims to identify and describe rehabilitation-specific registry systems with an emphasis on identifying outcomes that enable the assessment of vital areas and activities of daily living.

EVIDENCE ACQUISITION

A systematic scoping review was conducted. A systematic search was conducted up to August 2022 in MEDLINE/PubMed, Embase, Cochrane Library, Epistemonikos, and other search resources. Studies related to rehabilitation registries presented data on people with health problems that could limit their functioning were selected. The inclusion of studies/clinical registries was not limited by methodological design, year of publication, country, or language. The unit of analysis was rehabilitation registries. The measurement instruments used to assess the outcomes were explored to estimate the domain assessed from the vital areas related to functioning and disability as described by the International Classification of Functioning, Disability and Health (ICF). The vital areas were classified according to activities of daily living (ADLs).

EVIDENCE SYNTHESIS

Seventy-one registries in rehabilitation were identified. The registries included a median of 3 (IQR 2-5) assessment instruments designed to assess the impact of different rehabilitation programs. In total, 137 different assessment scales or instruments were identified. Each rehabilitation registry assessed 6 (IQR 2-8) domains of the ICF, and 15.4% of registries assessed all domains. The most assessed domain was "Mobility" (89.7%), and the least assessed was "General Tasks and Demands" (25.6%). In addition, 92.3% of rehabilitation registries assessed basic ADLs, 76.9% advanced ADLs, and 71.8% instrumental ADLs.

CONCLUSIONS

Although clinical registries do not claim to directly assess the impact of rehabilitation programs on people's functioning according to the ICF framework, it was identified that a low percentage of them assessed the nine vital areas through different outcome assessment instruments. However, most rehabilitation registries directly or indirectly assess some basic, instrumental, and advanced ADLs. The findings of this review highlight the need to improve the design of clinical registries focused on assessing the impact of rehabilitation programs to assess people in all areas of their lives.

Pilot testing of the International Council of Cardiovascular Prevention and Rehabilitation Registry

The International Council of Cardiovascular Prevention and Rehabilitation developed an International Cardiac Rehabilitation (CR) Registry (ICRR) to support CR programs in low-resource settings to optimize care provision and patient outcomes. This study assessed implementation of the ICRR, site data steward experience with on-boarding and data entry, and patient acceptability. Multimethod observational pilot involves (I) analysis of ICRR data from three centers (Iran, Pakistan, and Qatar) from inception to May 2022, (II) focus group with on-boarded site data stewards (also from Mexico and India), and (III) semistructured interviews with participating patients. Five hundred sixty-seven patients were entered. Based on volumes at each program, 85.6% of patients were entered in ICRR. 99.3% patients approached consented to participate. The average time to enter data at pre- and follow-up assessments by source was 6.8-12.6 min. Of 22 variables preprogram, completion was 89.5%. Among patients with any follow-up data, of four program-reported variables, completion was 99.0% in program completers and 51.5% in none; of 10 patient-reported variables, completion was 97.0% in program completers and 84.8% in none. The proportion of patients with any follow-up data was 84.8% in program completers, with 43.6% of noncompleters having any data entered other than completion status. Twelve data stewards participated in the focus group. Main themes were valuable on-boarding process, data entry, process of engaging patients, and benefits of participation. Thirteen patients were interviewed. Themes were good understanding of the registry, positive experience providing data, and value of lay summary and eagerness for annual assessment. Feasibility and data quality of ICRR were demonstrated.

Temporal trends in cardiovascular risk factors, lifestyle and secondary preventive medication for patients with myocardial infarction attending cardiac rehabilitation in Sweden 2006-2019: a registry-based cohort study

OBJECTIVES

Registries have been highlighted as means to improve quality of care. Here, we describe temporal trends in risk factors, lifestyle and preventive medication for patients after myocardial infarction (MI) registered in the quality registry Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART).

DESIGN

A registry-based cohort study.

SETTING

All coronary care units and cardiac rehabilitation (CR) centres in Sweden.

PARTICIPANTS

Patients attending a CR visit at 1-year post-MI 2006-2019 were included (n=81 363, 18-74 years, 74.7% men).

OUTCOME MEASURES

Outcome measures at 1-year follow-up included blood pressure (BP) <140/90 mm Hg, low-density lipoprotein-cholesterol (LDL-C)<1.8 mmol/L, persistent smoking, overweight/obesity, central obesity, diabetes prevalence, inadequate physical activity, and prescription of secondary preventive medication. Descriptive statistics and testing for trends were applied.

RESULTS

The proportion of patients attaining the targets for BP<140/90 mmHg increased from 65.2% (2006) to 86.0% (2019), and LDL-C<1.8 mmol/L from 29.8% (2006) to 66.9% (2019, p<0.0001 both). While smoking at the time of MI decreased (32.0% to 26.5%, p<0.0001), persistent smoking at 1 year was unchanged (42.8% to 43.2%, p=0.672) as was the prevalence of overweight/obesity (71.9% to 72.9%, p=0.559). Central obesity (50.5% to 57.0%), diabetes (18.2% to 27.2%) and patients reporting inadequate levels of physical activity (57.0% to 61.5%) increased (p<0.0001 for all). From 2007, >90.0% of patients were prescribed statins and approximately 98% antiplatelet and/or anticoagulant therapy. Angiotensin-converting enzyme inhibitor/angiotensin receptor blocker prescription increased from 68.7% (2006) to 80.2% (2019, p<0.0001).

CONCLUSIONS

While little change was observed for persistent smoking and overweight/obesity, large improvements were observed for LDL-C and BP target achievements and prescription of preventive medication for Swedish patients after MI 2006-2019. Compared with published results from patients with coronary artery disease in Europe during the same period, these improvements were considerably larger. Continuous auditing and open comparisons of CR outcomes might possibly explain some of the observed improvements and differences.

A Global Overview of Acute Coronary Syndrome Registries: A Systematic Review

The present study was conducted with the aim of identifying, and summarizing the characteristics of ACS registries at national, multinational and international levels. Literature was searched using keywords in the title and/or abstract without any time limit ending in March, 2021. After excluding duplicates, 2 reviewers independently reviewed the titles and/or abstracts and full text for inclusion. Each reviewer independently extracted the characteristics of the registries from included papers. Finally, the extracted characteristics were confirmed by a second reviewer. Out of the 1309 papers included, 71 ACS registries were identified (including 60 national and 11 multinational and international registries). Most national registries were being used in Europe. Most registries focused on measuring quality. In more than half of the registries, all types of ACS patients were enrolled. The diagnostic and drug classification systems were mentioned in eight and five registries, respectively. The design of 55 registries was hospital-based. The ability of computerized audit checks was made for 34 registries. More than half of the registries had patient consent and had a web-based design. In all the ACS registries, patient characteristics, clinical characteristics and treatment characteristics were recorded and post-discharge follow-up information was recorded in 45 registries. In the current situation and given that a limited number of countries in the world have national ACS registries, reviewing the results of this study and modeling the registries implemented in the leading countries can help countries without a registry to design it.

Study Design of the Japanese Association of Cardiac Rehabilitation Registry (J-CARRY) ― Protocol for a Prospective, Multicenter, Open Registry ―

Background: Guidelines for the prevention and management of cardiovascular disease (CVD) highly recommend cardiac rehabilitation (CR) on the basis of abundant evidence of its effectiveness. However, the current understanding and dissemination of CR in Japan are far from sufficient.

Methods and Results: The Japanese Association of Cardiac Rehabilitation Registry (J-CARRY) is an academic society-led prospective multicenter observational registry conducted by the Registration and Facility Accreditation System Committee of the Japanese Association of Cardiac Rehabilitation. Data are collected prospectively using an electronic data capture system. Items related to patients’ clinical background and CR, as well as mortality and major adverse cardiac and cerebrovascular events, will be collected in all cases. This Registry started in May 2014, and the number of participating medical institutions is expected to increase to >30; the targeted number of cases exceeded 3,000 per year as of April 30, 2022. Focusing on late Phase II data collection is a novel and significantly different approach compared with previous studies. The results of this study are currently under investigation.

Conclusions: J-CARRY will provide real-world data regarding the current status and prognosis of CVD in patients who undergo Phase II CR in Japan.

Overview of registries for anaphylaxis: a scoping review

OBJECTIVE

This review aimed to describe the scope and operational features of anaphylaxis registries, and to assess their contribution to improving knowledge of anaphylaxis and care of patients who experience anaphylaxis by measuring their research output.

INTRODUCTION

Structured data collection and reporting systems, such as registries, are needed to better understand the burden of anaphylaxis and to protect the growing number of patients with severe allergy. There is a need to characterize current anaphylaxis registries to identify their value in anaphylaxis surveillance, management, and research. Information synthesized in this review will provide knowledge on benefits and gaps in current registries, which may inform the implementation and global standardization of future anaphylaxis reporting systems.

INCLUSION CRITERIA

This scoping review considered literature describing registries worldwide that enroll patients who have experienced anaphylaxis. Published and gray literature sources were included if they described the scope and operational features of anaphylaxis registries.

METHODS

This review followed the JBI methodology for scoping reviews. Embase, MEDLINE, Scopus, and CINAHL were searched for relevant articles. Identified keywords and index terms were adapted for searches of gray literature sources, using Google advanced search functions. Only full-text studies in English were considered for inclusion. Two independent reviewers conducted title and abstract screening and those that did not meet the inclusion criteria were excluded. The full text of potentially relevant articles were retrieved; full-text screening and data extraction were also conducted by two independent reviewers. Any discrepancies were resolved through discussion or with a third reviewer. Tables and a narrative summary were used to describe and compare the scope and features (eg, inclusion criteria, patient demographics, clinical symptoms) of the identified anaphylaxis registries, and to outline their output to assess their contribution to research and clinical practice for anaphylaxis.

RESULTS

A total of 77 full-text publications and eight gray literature sources were used to extract data. The literature search identified 19 anaphylaxis registries, with sites in 28 countries including Europe, the United Kingdom, Canada, the United States, Korea, and Australia. The main purposes of the identified registries were to collect clinical data for research; provide clinical support tools to improve patient care; and operate as allergen surveillance systems to protect the wider community with allergies. Differences in inclusion and health care settings exist, with 11 collecting data on anaphylaxis of any cause, two on food reactions alone, three on fatal anaphylaxis, one on perioperative anaphylaxis, and two on allergic reactions (including anaphylaxis). Five registries enroll cases in allergy centers, five in hospital settings, one in schools, and others target a combination of general practitioners, specialists in emergency departments, and other relevant hospital departments and allergy outpatient clinics. Only three registries operate under a mandatory framework. A total of 57 publications were considered research outputs from registries. All registries except two have published studies from collected data, with the greatest number of articles published from 2019 to the present. Publications mostly addressed questions regarding demographic profile, causes and cofactors, severity, fatal reactions, and gaps in management.

CONCLUSIONS

This review demonstrated that anaphylaxis registries differ in their scope and operation, having been established for different purposes. Importantly, registries have contributed significantly to research, which has highlighted gaps in anaphylaxis management, provoking allergens, and informed targets for prevention for severe and fatal events. Beyond this, registries relay information about anaphylaxis to clinicians and regulatory bodies to improve patient care and protect the community. The ability to link registry data with other health datasets, standardization of data across registries, and incorporation of clinical care indicators to promote quality health care across the health system represent important targets for future systems.

Design, development, and evaluation of a registry system for hyperbaric oxygen therapy: A methodological study

Background and Aims

Hyperbaric oxygen therapy (HBOT), utilizes 100% oxygen at pressures greater than sea-level atmospheric pressure, for the treatment of conditions in which the tissues starve for oxygen. The Undersea and Hyperbaric Medical Society (UHMS) has granted HBOT approval for the treatment of various conditions. On the other hand, applying informatics registry systems can improve care delivery, ameliorate outcomes, and reduce the costs and medical errors for the patients receiving HBOT treatment. Therefore, we aimed to design, develop, and evaluate a registry system for patients undergoing HBOT.

Methods

In the first phase, the conceptual and logical models were designed after conducting symposiums with experts and having other experts review the models. In the second phase, the system was developed on the web using ASP.NET  and C# programming languages frameworks. The last phase involved Nielsen's heuristic evaluation method for the system's usability. Five experts evaluated the system, including three health information management specialists and two medical informatics specialists.

Results

The hyperbaric patient information registry system (HPIRS) interacts with three types of users-a specialist physician, a nurse, and a system administrator. A scenario for each predefined activity was designed, and all the information was stored in the SQL servers. The five experts independently found 152 issues, of which 84 were duplicates. The 68 distinct issues of the system were then resolved.

Conclusions

The design and development of such registry systems can make data available and stored carefully to improve clinical care and medical research and decrease costs and errors. These registries can provide the healthcare systems with E-health applications, improved data management, more secure data transfer, and support for statistical reporting. The implemented heuristic evaluation method can also provide a low-cost and readily available system to fix the issues of the designed systems.

Qualitative study measuring the usability of the International Cardiac Rehabilitation Registry

OBJECTIVE

Cardiac rehabilitation (CR) is a comprehensive model of secondary preventive care. There is a wide variety in implementation characteristics globally, and hence quality control is paramount. Thus, the International Council of Cardiovascular Prevention and Rehabilitation was urged to develop a CR registry. The purpose of this study was to test the perceived usability of the International Cardiac Rehabilitation Registry (ICRR) to optimise it.

DESIGN

This was a qualitative study, comprising virtual usability tests using a think-aloud method to elicit feedback on the ICRR, while end-users were entering patient data, followed by semistructured interviews.

SETTING

Ultimately, 12 tests were conducted with CR staff (67% female) in low-resource settings from a variety of disciplines in all regions of the world but Europe before saturation was achieved.

PRIMARY OUTCOME MEASURE

Participants completed the System Usability Scale. Interviews were transcribed verbatim except to preserve anonymity, and coded using NVIVO by two researchers independently. The Unified Theory of Acceptance and Use of Technology 2 informed analysis.

RESULTS

The ICRR was established as easy to use, relevant, efficient, with easy learnability, operability, perceived usefulness, positive perceptions of output quality and high end-user satisfaction. System usability was 83.75, or 'excellent' and rated 'A'. Four major themes were deduced from the interviews: (1) ease of approvals, adoption and implementation; (2) benefits for programmes, (3) variables and their definitions, as well as (4) patient report and follow-up assessment. Based on participant observation and utterances, suggestions for changes to the ICRR were implemented, including to the programme survey, on-boarding processes, navigational instructions, inclusion of programme logos, direction on handling unavailable data and optimising data completeness, as well as policies for authorship and programme certification.

CONCLUSIONS

With usability of the ICRR optimised, pilot testing shall ensue.

Development of the International Cardiac Rehabilitation Registry Including Variable Selection and Definition Process

Introduction:

The International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) is developing a registry (ICRR) specifically for low-resource settings, where the burden of cardiovascular diseases is greatest and the need for program development highest. Herein we describe the development process, including the variable selection process.

Method:

Following a literature search on registry best practices, a stepwise model for ICRR development was identified. Then, based on recommendations by Core Outcome Set-STAndards for Development (COS-STAD), we underwent a process to identify variables. All available CR registries were contacted to request their data dictionaries, reviewed CR quality indicators and guideline recommendations, and searched for common data elements and core outcome sets; 35 unique variables (including patient-reported outcomes) were selected for potential inclusion. Twenty-one purposively-identified stakeholders and experts agreed to serve on a Delphi panel. Panelists rated the variables in an online survey, and suggested potential additional variables; A webcall was held to reach consensus on which to include/exclude. Next, panelists provided input to finalize each variable definition, and rated which associated indicators should be used for benchmarking in registry dashboards and a patient lay summary; a second consensus call was held. A 1-month public comment period ensued.

Results:

First, registry objectives and governance were approved by ICCPR, including data quality and access policies. The protocol was developed, for public posting. For variable selection, the overall mean rating was 6.1 ± 0.3/7; 12 were excluded, some of which were moved to a program survey, and others were revised. Two variables were added in an annual follow-up, resulting in 13 program and 16 patient-reported variables. Legal advice was sought to finalize ICRR agreements. Ethics approvals were obtained. Usability testing is now being initiated.

Conclusion:

It is hoped this will serve to harmonize CR assessment internationally and enable quality improvement in CR delivery in low-resource settings.

Measuring True Change in Individual Patients: Reliable Change Indices of Cardiac Rehabilitation Outcomes, and Implications for Quality Indicators

BACKGROUND

Mediated by outcomes such as improved exercise capacity, cardiac rehabilitation (CR) reduces morbidity and mortality. For accuracy, an individual CR patient's change must be measured reliably, an issue not typically considered in practice. Drawing from psychometric theory, we calculated reliable change indices (RCIs), to measure individual CR patients' true clinical change, apart from that from error and test practice/exposure, in exercise capacity, anxiety, and depression.

METHODS

Indirectly calculated exercise capacity (peak metabolic equivalents [METs]) and psychological symptoms were each measured twice, 1 week apart, by administering treadmill tests or the Hospital Anxiety and Depression Scale (HADS) to separate samples of 35 (mean age: 59.0 years; 6 women) and 96 (mean age: 64.4 years; 32 women) CR patients, respectively. Using test-retest reliability and mean difference scores from these samples to estimate error and practice/exposure effects, we calculated RCIs for a separate cohort (n = 2066; mean age: 62.0 years; 533 women) who completed 6-month CR, and compared change distributions (worsened/unchanged/improved) based on critical RCIs, mean and percent changes, cut-off scores, and standard deviations.

RESULTS

Practice/exposure effects were nonsignificant, except the mean HADS anxiety score decreased significantly (P ≤ 0.013; d = 0.17, small effect). Test-retest reliabilities were high (METs r = 0.934; HADS anxiety score r = 0.912; HADS depression score r = 0.90; P < 0.001). Among 2066 CR patients, RCI distributions differed (P < 0.001) from those of most other change criteria.

CONCLUSIONS

Change ascertainment depends on criterion choice. A Canadian Cardiovascular Society CR quality indicator of increase by 0.5 MET may be too small to assess individuals' functional capacity change. RCIs offer a pragmatic approach to benchmarking reliable change frequency, and pending further validation, could be used for feedback to individual patients.

Efficacy of psychological interventions on psychological outcomes in coronary artery disease: systematic review and meta-analysis

BACKGROUND

The benefits of cognitive-behavioral treatment (CBT) and positive psychology therapy (PPT) in patients with cardiovascular disease are still not well defined. We assessed the efficacy of CBT and PPT on psychological outcomes in coronary artery disease (CAD) patients.

METHODS

Randomized controlled trials evaluating CBT or PPT in CAD patients published until May 2018 were systematically analyzed. Primary outcomes were depression, stress, anxiety, anger, happiness, and vital satisfaction. Random effects meta-analyses using the inverse variance method were performed. Effects were expressed as standardized mean difference (SMD) or mean differences (MD) with their 95% confidence intervals (CIs); risk of bias was assessed with the Cochrane tool.

RESULTS

Nineteen trials were included (n = 1956); sixteen evaluated CBT (n = 1732), and three PPT (n = 224). Compared with control groups, depressive symptoms (13 trials; SMD -0.80; 95% CI -1.33 to -0.26), and anxiety (11 trials; SMD -1.26; 95% CI -2.11 to -0.41) improved after the PI, and depression (6 trials; SMD -2.08; 95% CI -3.22 to -0.94), anxiety (5 trials; SMD -1.33; 95% CI -2.38 to -0.29), and stress (3 trials; SMD -3.72; 95% CI -5.91 to -1.52) improved at the end of follow-up. Vital satisfaction was significantly increased at follow-up (MD 1.30, 0.27, 2.33). Non-significant effects on secondary outcomes were found. Subgroup analyses were consistent with overall analyses.

CONCLUSION

CBT and PPT improve several psychological outcomes in CAD patients. Depression and anxiety improved immediately after the intervention while stress and vital satisfaction improve in the mid-term. Future research should assess the individual role of CBT and PPT in CAD populations.

Cardiac Rehabilitation: Under-Utilized Globally

PURPOSE OF REVIEW

Cardiac rehabilitation (CR) is grossly under-utilized. This review summarizes current knowledge about degree of CR utilization, reasons for under-utilization, and strategies to increase use.

RECENT FINDINGS

ICCPR's global CR audit quantified for the first time the number of additional CR spots needed per year to treat indicated patients, so there are programs they may use. The first randomized trial of automatic/systematic CR referral has shown it results in significantly greater patient completion. Moreover, the recent update of the Cochrane review on interventions to increase use has provided unequivocal evidence on the significant impact of clinician CR encouragement at the bedside; a course is now available to train clinicians. The USA is leading the way in implementing automatic referral with inpatient-clinician CR discussions. Suggestions to triage patients based on risk to less resource-intensive, unsupervised program models could simultaneously expand capacity and support patient adherence.

Effects of Phase II Comprehensive Cardiac Rehabilitation on Risk Factor Modification and Exercise Capacity in Patients With Acute Coronary Syndrome ― Results From the JACR Registry ―

Background: Cardiac rehabilitation (CR) is categorized as a Class I recommendation in guidelines for the management of patients with acute coronary syndrome (ACS); however, nationwide studies on CR in patients with ACS remain limited in Japan.

Methods and Results: The Japanese Association of Cardiac Rehabilitation (JACR) Registry is a nationwide, real-world database for patients participating in CR. From the JACR Registry database, we analyzed 924 patients participating in Phase II CR in 7 hospitals between September 2014 and December 2016. The mean age of patients was 65.9±12.0 years, and 80% were male. The prevalence of ST-elevation myocardial infarction (STEMI), non-STEMI (NSTEMI), and unstable angina pectoris (UAP) was 58%, 9%, and 33%, respectively. The prevalence of hypertension, diabetes, dyslipidemia, current smoking, and a family history was 55%, 27%, 67%, 21%, and 10%, respectively. Among the entire CR cohort at baseline, 96%, 78%, and 92% were treated with aspirin, β-blockers, and statins, respectively. After CR, the values of body mass index, the lipid profile, and exercise capacity significantly improved in the STEMI, NSTEMI and UAP groups.

Conclusions: In the JACR Registry, a high rate of guideline-recommended medications at baseline and improvements in both coronary risk factors and exercise capacity after CR were observed in patients with ACS.

Cardiac Rehabilitation Quality Improvement: A NARRATIVE REVIEW

PURPOSE

Despite evidence of the effectiveness of cardiac rehabilitation (CR), there is wide variability in programs, which may impact their quality. The objectives of this review were to (1) evaluate the ways in which we measure CR quality internationally; (2) summarize what we know about CR quality and quality improvement; and (3) recommend potential ways to improve quality.

METHODS

For this narrative review, the literature was searched for CR quality indicators (QIs) available internationally and experts were also consulted. For the second objective, literature on CR quality was reviewed and data on available QIs were obtained from the Canadian Cardiac Rehabilitation Registry (CCRR). For the last objective, literature on health care quality improvement strategies that might apply in CR settings was reviewed.

RESULTS

CR QIs have been developed by American, Canadian, European, Australian, and Japanese CR associations. CR quality has only been audited across the United Kingdom, the Netherlands, and Canada. Twenty-seven QIs are assessed in the CCRR. CR quality was high for the following indicators: promoting physical activity post-program, assessing blood pressure, and communicating with primary care. Areas of low quality included provision of stress management, smoking cessation, incorporating the recommended elements in discharge summaries, and assessment of blood glucose. Recommended approaches to improve quality include patient and provider education, reminder systems, organizational change, and advocacy for improved CR reimbursement. An audit and feedback strategy alone is not successful.

CONCLUSIONS

Although not a lot is known about CR quality, gaps were identified. The quality improvement initiatives recommended herein require testing to ascertain whether quality can be improved.

Efficacy of extended, comprehensive outpatient cardiac rehabilitation on cardiovascular risk factors: A nationwide registry

Aim

Cardiac rehabilitation (CR) is a key component of the treatment of cardiac diseases. The Austrian outpatient CR model is unique, as it provides patients with an extended professionally supervised, multidisciplinary program of 4–6 weeks of phase II (OUT-II) and 6–12 months of phase III (OUT-III) CR. The aim of this analysis was to assess the efficacy of the Austrian outpatient CR model using a nationwide registry.

Methods

Data of all consecutive patients ( N = 7560) who completed OUT-II and/or OUT-III between 1 January 2005 and 31 December 2015 were entered prospectively into a registry. OUT-III patients were analyzed separately according to whether the preceding phase II was performed as outpatient (OUT-II/OUT-III, N = 2403) or in-patient (IN-II/OUT-III, N = 2789). All patients underwent assessment of anthropometry, resting blood pressure, lipid profile, fasting blood glucose, exercise capacity, quality of life, anxiety and depression.

Results

During OUT-II, patients significantly improved their metabolic risk factor profile and increased exercise capacity by 14.3%. OUT-II/OUT-III patients achieved an additional increase in exercise capacity by 10%, further improvement in high-density lipoprotein (HDL) and stabilization of the remaining risk factors. IN-II/OUT-III patients increased their maximal exercise capacity by 18.4% and there was improvement in blood pressure, HDL, low-density lipoprotein and glucose levels.

Conclusion

Extended, professionally supervised, multidisciplinary outpatient CR in a large nationwide registry of consecutive patients consistently improved maximal exercise capacity and relevant modifiable cardiovascular risk factors beyond effects seen after IN- or OUT-II alone.

Nature of Cardiac Rehabilitation Around the Globe

BACKGROUND

Cardiac rehabilitation (CR) is a clinically-effective but complex model of care. The purpose of this study was to characterize the nature of CR programs around the world, in relation to guideline recommendations, and compare this by World Health Organization (WHO) region.

METHODS

In this cross-sectional study, a piloted survey was administered online to CR programs globally. Cardiac associations and local champions facilitated program identification. Quality (benchmark of ≥ 75% of programs in a given country meeting each of 20 indicators) was ranked. Results were compared by WHO region using generalized linear mixed models.

FINDINGS

111/203 (54.7%) countries in the world offer CR; data were collected in 93 (83.8%; N = 1082 surveys, 32.1% program response rate). The most commonly-accepted indications were: myocardial infarction (n = 832, 97.4%), percutaneous coronary intervention (n = 820, 96.1%; 0.10), and coronary artery bypass surgery (n = 817, 95.8%). Most programs were led by physicians (n = 680; 69.1%). The most common CR providers (mean = 5.9 ± 2.8/program) were: nurses (n = 816, 88.1%; low in Africa, p < 0.001), dietitians (n = 739, 80.2%), and physiotherapists (n = 733, 79.3%). The most commonly-offered core components (mean = 8.7 ± 1.9 program) were: initial assessment (n = 939, 98.8%; most commonly for hypertension, tobacco, and physical inactivity), risk factor management (n = 928, 98.2%), patient education (n = 895, 96.9%), and exercise (n = 898, 94.3%; lower in Western Pacific, p < 0.01). All regions met ≥ 16/20 quality indicators, but quality was < 75% for tobacco cessation and return-to-work counseling (lower in Americas, p = < 0.05).

INTERPRETATION

This first-ever survey of CR around the globe suggests CR quality is high. However, there is significant regional variation, which could impact patient outcomes.

Facilitators for using data from a quality registry in local quality improvement work: a cross-sectional survey of the Danish Cardiac Rehabilitation Database

OBJECTIVES

To investigate use of data from a clinical quality registry for cardiac rehabilitation in Denmark, considering the extent to which data are used for local quality improvement and what facilitates the use of these data, with a particular focus on whether there are differences between frontline staff and managers.

DESIGN

Cross-sectional nationwide survey study.

SETTING, METHODS AND PARTICIPANTS

A previously validated, Swedish questionnaire regarding use of data from clinical quality registries was translated and emailed to frontline staff, mid-level managers and heads of departments (n=175) in all 30 hospital departments participating in the Danish Cardiac Rehabilitation Database. Data were analysed descriptively and through multiple linear regression.

RESULTS

Survey response rate was 58% (101/175). Reports of registry use at department level (measured through an index comprising seven items; score min 0, max 7, where a low score indicates less use of data) varied significantly between groups of respondents: frontline staff mean score 1.3 (SD=2.0), mid-level management mean 2.4 (SD=2.3) and heads of departments mean 3.0 (SD=2.5), p=0.006. Overall, department level use of data was positively associated with higher perceived data quality and usefulness (regression coefficient=0.22, p=0.019), management request for data (regression coefficient=0.40, p=0.008) and personal motivation of the respondent (regression coefficient=1.63, p<0.001). Among managers, use of registry data was associated with data quality and usefulness (regression coefficient=0.43, p=0.027), and among frontline staff, reported data use was associated with management involvement in quality improvement work (regression coefficient=0.90, p=0.017) and personal motivation (regression coefficient=1.66, p<0.001).

CONCLUSIONS

The findings suggest relatively sparse use of data in local quality improvement work. A complex interplay of factors seem to be associated with data use with varying aspects being of importance for frontline staff and managers.

Impact of in-hospital cardiac rehabilitation on mortality and readmissions in heart failure: A population study in Lombardy, Italy, from 2005 to 2012

Aims

The 2016 European guidelines for the diagnosis and treatment of heart failure classified cardiac rehabilitation as a mandatory class I intervention. We aimed to analyse in heart failure patients the impact of an in-hospital cardiac rehabilitation programme on all-cause mortality and readmissions.

Methods

From the Lombardy healthcare administrative database, we analysed in patients with incident heart failure, from 2005 to 2012, the number of all hospitalisations, cardiac rehabilitation admissions, post-discharge deaths, outpatient drug prescriptions and visits. We divided patients into hospitalised for heart failure in acute care only (group A) versus patients with one or more admission to cardiac rehabilitation for an in-hospital cardiac rehabilitation programme (group B).

Results

Of 140,552 incident cases, 100,843 (71%) were in group A and 39,709 (29%) in group B. Patients in group B had 3.26 ± 1.78 admissions to acute care before referral to an in-hospital cardiac rehabilitation programme. Male gender, age in women and comorbidities (more than two) were higher in group B ( P < 0.0001). Patients in group B had a higher number of interventional procedures ( P < 0.0001), drug prescription and outpatient visit rate ( P < 0.0001). Total mortality was 30% in group A versus 29% in group B. At Cox and logistic regression analyses, after adjustment for covariates, group B had a significantly lower risk of mortality (hazard ratio 0.5768, 95% confidence interval 0.5650–0.5888, P < 0.0001) and readmissions (0.7997, 0.7758–0.8244, P < 0.0001) than group A.

Conclusion

This study showed in a large population of heart failure patients that in-hospital cardiac rehabilitation is associated with a reduction of all-cause mortality and rehospitalisations in heart failure. Given its potential significant benefit, referral of heart failure patients to an in-hospital cardiac rehabilitation programme should be promoted.

"Struggling with practices" - a qualitative study of factors influencing the implementation of clinical quality registries for cardiac rehabilitation in England and Denmark

Background

The use of clinical quality registries as means for data driven improvement in healthcare seem promising. However, their use has been shown to be challenged by a number of aspects, and we suggest some may be related to poor implementation. There is a paucity of literature regarding barriers and facilitators for registry implementation, in particular aspects related to data collection and entry. We aimed to illuminate this by exploring how staff perceive the implementation process related to the registries within the field of cardiac rehabilitation in England and Denmark.

Methods

A qualitative, interview-based study with staff involved in collecting and/or entering data into the two case registries (England N = 12, Denmark N = 12). Interviews were analysed using content analysis. The Consolidated Framework for Implementation Research was used to guide interviews and the interpretation of results.

Results

The analysis identified both similarities and differences within and between the studied registries, and resulted in clarification of staffs´ experiences in an overarching theme: ´Struggling with practices´ and five categories; the data entry process, registry quality, resources and management support, quality improvement and the wider healthcare context. Overall, implementation received little focused attention. There was a lack of active support from management, and staff may experience a struggle of fitting use of a registry into a busy and complex everyday practice.

Conclusion

The study highlights factors that may be important to consider when planning and implementing a new clinical quality registry within the field of cardiac rehabilitation, and is possibly transferrable to other fields. The results may thus be useful for policy makers, administrators and managers within the field and beyond. Targeting barriers and utilizing knowledge of facilitating factors is vital in order to improve the process of registry implementation, hence helping to achieve the intended improvement of care processes and outcomes.

International Comparison of Thalassemia Registries: Challenges and Opportunities

Background:

Patient registries use standardized methods to systematically gather uniform data for specific groups of patients managed in clinical practice to evaluate specified outcomes.

Aim:

The objective of this study was to identify and describe structures of the identified thalassemia registries in worldwide and summarize their key characteristics.

Methods:

We reviewed the literature on thalassemia registries. A search of PubMed, Scopus, ProQuest, and Science Direct databases was conducted in September 2018. We also reviewed the existing thalassemia registry websites in different countries. The keywords used to our search were as follows: Thalassemia, Hemoglobinopathy, Registry, Database, and Registration System. Some features such as the name of registry, funding source, objectives of the registry, minimum data set, and methods of data collection were determined.

Results:

We identified 16 thalassemia registries operating on a multinational, national, or regional level between1984 and 2016. Most of these aimed to improve the diagnosis and management of control programs. Government funding was the most common funding source for registries. Furthermore, the most common method of data submission was Web-based data entry. The data were entered by a member of the clinical team or a nominated data manager.

Conclusion:

Registries provide a positive return on investment; their establishment and maintenance require ongoing support by government, policy makers, research funding bodies, clinicians, thalassemia patients and their caregivers. However, the results of research suggest the establishment of an international network for coordination and collaboration between thalassemia registries.

Development of Quality Indicators for Cardiac Rehabilitation in Australia: A Modified Delphi Method and Pilot Test

BACKGROUND

International guidelines recommend cardiac rehabilitation (CR) for secondary prevention of cardiovascular disease, however, it is underutilised and the quality of content and delivery varies widely. Quality indicators (QIs) for CR are used internationally to measure clinical practice performance, but are lacking in the Australian context. This study reports the development of QIs for minimum dataset (MDS) for CR and the results of a pilot test for feasibility and applicability in clinical practice in Australia.

METHODS

A modified Delphi method was used to develop initial QIs which involved a consensus approach through a series of face-to-face and teleconference meetings of an expert multidisciplinary panel (n=8), supplemented by an environmental scan of the literature and a multi-site pilot test.

RESULTS

Eight (8) QIs were proposed and sent to CR clinicians (n=250) electronically to rate importance, current data collection status, and feasibility of future collection. The top six of these QIs were selected with an additional two key performance indicators from the New South Wales (NSW) Ministry of Health and two QIs from international registers for a draft MDS. The pilot test in 16 sites (938 patient cases) demonstrated median performance of 93% (IQR 47.1-100%). All 10 QIs were retained and one further QI related to diabetes was added for a final draft MDS.

CONCLUSIONS

The MDS of 11 QIs for CR provides an important foundation for collection of data to promote the quality of CR nationally and the opportunity to participate in international benchmarking.

Implementation of a politically initiated national clinical guideline for cardiac rehabilitation in hospitals and municipalities in Denmark

A politically initiated national clinical guideline was launched in Denmark in 2013 to improve quality and equality of cardiac rehabilitation (CR) services. The guideline is to be implemented in both hospital and community (municipality) settings due to shared responsibility for provision of CR services. Little is known about implementation outcomes of a guideline in these two settings. We aimed to study this by determining the extent to which Danish CR services in hospitals and municipalities adhered to national recommendations following the launch of the guideline. The study employed an observational, longitudinal design. Data were gathered by a questionnaire survey to compare CR services at baseline, measured in 2013 immediately before the guideline was launched, with CR services at a two-year follow up in 2015. All Danish hospital departments offering CR services (N = 36) and all municipalities (N = 98) were included. Data were analysed using inferential statistics. Hospitals reported improvement of both content and quality of CR services. Municipalities reported no change in content of services, and lower level of fulfilment of one quality aspect. The results suggest that the guideline had different impact in hospitals and municipalities and that the differences in content and quality of services between the two settings increased in the study period, thus contradicting the guideline´s aim of uniform, evidence-based content of CR services across settings.

Sex and Racial Disparities in Cardiac Rehabilitation Referral at Hospital Discharge and Gaps in Long-Term Mortality

Background

Cardiac rehabilitation (CR) referral is recommended for eligible patients, regardless of sex or race. It is unclear whether inequality in CR referral practices was associated with patients’ long‐term survival.

Methods and Results

We linked the American Heart Association Get With The Guidelines Coronary Artery Disease registry with Medicare claims data for 48 993 coronary artery disease patients from 365 hospitals across the United States between 2003 and 2009. We used generalized estimation equations to estimate the association between CR referral and mortality accounting for clustering within hospitals. Between 2003 and 2009, only 40% of eligible patients received CR referrals. Females were 12% less likely to receive CR referral compared with males. Black, Hispanic, and Asian patients were 20%, 36%, and 50% less likely, respectively, to receive CR referral than white patients. CR referral was associated with 40% lower 3‐year all‐cause mortality. Women and minorities who received CR referral at hospital discharge had significantly lower mortality compared with those who did not (odds ratios=0.61 [95% confidence interval, 0.56–0.66] for women, 0.75 [95% confidence interval, 0.63–0.88] for black, 0.62 [95% confidence interval, 0.50–0.79] for Hispanic, and 0.63 [95% confidence interval, 0.46–0.85] for Asian patients). Seven percent of the black versus white mortality gap could potentially be reduced by equitable CR referral.

Conclusions

CR referral rates at hospital discharge remained low. Gaps in receiving CR referral at hospital discharge were large for women and minorities, and the mortality gap could potentially be reduced through elimination of inequality in CR referral.

Availability and characteristics of cardiac rehabilitation programs in one Brazilian state: a cross-sectional study

BACKGROUND

Cardiac rehabilitation (CR) is a recommended model of care for cardiovascular diseases; however, is not widely available and is underutilized, especially in low- and middle-income countries.

OBJECTIVES

To identify the CR programs available in one Brazilian state (Minas Gerais; MG) and describe their characteristics by funding type.

METHODS

In this multi-center descriptive study, CR programs were identified in four MG regions and 41 CR coordinators were sent a survey to report the characteristics of their programs, including CR components described in guidelines and barriers to patients' participation. Descriptive and comparative analysis between public and private programs were carried out.

RESULTS

Forty-one CR programs were identified, only 21.9% public. Nineteen completed the survey. The majority of CR programs offered initial assessment and physical training. Components of comprehensive CR programs that were rarely offered included treatment of tobacco dependence, psychological support and lipid control. Physical therapists were present in all CR programs. The six-minute walk test was used in most programs to assess functional capacity. Programs were located intra-hospital only in public hospitals. Phase 2 (initial outpatient) and phase 4 (maintenance) were offered significantly more in private programs when compared to public ones. The main barrier for CR participation was the lack of referral.

CONCLUSIONS

The availability of CR programs in MG state is low, especially public programs. Most programs do not offer all core components of CR.
