Adapting an evidence-based, home cardiac rehabilitation programme for people with heart failure and their caregivers to the Danish context: DK:REACH-HF study.

AIMS: Adapting interventions with an existing evidence base offers a more efficient approach than development of a new intervention. The aim of this study was to describe the process of adapting a home-based cardiac rehabilitation (CR) programme (REACH-HF) intervention originally developed in the United Kingdom for people with heart failure (HF) to the Danish health system - the 'DK:REACH-HF' programme. METHODS AND RESULTS: We followed methodological framework for the conduct and reporting of studies adapting interventions, utilizing documentary analysis, qualitative interviews, stakeholder consultations, and mapping of the Danish policy context. Our study found broad support for the REACH-HF intervention as an alternative to existing centre-based CR. We also identified three key areas of adaptation for the Danish context. First, reduce the word-count of the intervention's resources by linking to existing publicly available CR materials. Second, whilst retaining REACH-HF core components, adapt its content and delivery to reflect differences between Denmark and United Kingdom. Thirdly, to develop a digital version of the intervention. CONCLUSION: Using an evidence-based approach, we successfully adapted the REACH-HF intervention to the context of the Danish healthcare setting, maintaining core components of the original intervention, and developing both a paper based and digital version of the programme material. To inform scaled national implementation of the DK:REACH-HF programme, we seek to undertake a pilot study to test the adapted intervention materials feasibility and acceptability to healthcare practitioners, patients, and their caregivers and confirm the positive impact on the outcomes of HF patients and caregivers.

Use of health services and perceived need for information and follow-up after percutaneous coronary intervention.

OBJECTIVE: Few patients achieve full control of their coronary artery disease (CAD) risk factors. Follow-up, such as cardiac rehabilitation, is important to increase adherence to lifestyle changes and treatment, to improve the patient's risk profile, and to treat established complications of CAD clinical events. However, the type of follow-up patients receive varies. Therefore, the aim of this research note was to describe and compare patients' self-reported use of health services, the type of follow-up patients reported to prefer, and the type of information patients reported to be important, in two countries with different follow-up practices after PCI. RESULTS: We included 3417 patients in Norway and Denmark, countries with different follow-up strategies after PCI. The results showed large differences between the countries regarding health services used. In Denmark the most frequently used health services were consultations at outpatient clinics followed by visits to the general practitioner and visits to the fitness centre, whereas in Norway visits to the general practitioner were most common, followed by rehospitalisation and no follow-up used. However, patients found the same type of follow-up and information important in both countries. Patients' perceived need for follow-up and information decreased over time, suggesting a need for early follow-up when the patients are motivated. TRIAL REGISTRATION: NCT03810612 (18/01/2019).

Effects of screening for anxiety and depression in patients with ischaemic heart disease - a nationwide Danish register study.

AIM: To investigate the effect of screening for anxiety and depression (AD) in patients with ischaemic heart disease (IHD) on the likelihood of receiving treatment for AD. METHODS: We used a nationwide dataset of all Danish patients with an incident IHD diagnosis in the period 2015-2018 (N = 80,701) of which 20,461 (25%) were exposed to screening for AD as part of cardiac rehabilitation. A binary composite indicator for the use of any AD treatment (prescriptions of AD drugs, general practitioner (GP) counselling or referral to a psychologist), was modelled as the dependent variable. The probability of receiving AD treatment was estimated using linear probability and instrumental variable regression models. RESULTS: Exposure to AD screening was lower for patients with low income (change in probability -0.67, 95% CI -0.76; -0.59), low education (change in probability -0.16, 95% CI -0.20; -0.13), and a high comorbidity burden (change in probability -0.09, 95% CI -0.10; -0.07). Screened patients had a lower conditional probability of AD treatment (change in probability -0.0061, p < 0.001) than non-screened patients. The patient's GP also had an impact on the probability of being referred for AD treatment. Using an instrumental variable approach did not affect the results. CONCLUSIONS: Screening for AD was subject to selection at the patient level; patients at lower risk of AD had a higher probability of being screened. Hence, extending systematic screening to cover a larger population may not achieve a noticeable increase in the uptake of AD treatment if it is not supported by appropriate measures to reduce reverse selection into screening.

Return to work: does cardiac rehabilitation make a difference? Danish nationwide register-based study.

AIM: to assess whether participation in cardiac rehabilitation affects the probability of returning to work after ischaemic heart disease. METHODS: the study population consisted of 24,509 patients (18-70 years of age) discharged from an inpatient admission at a Danish hospital during 2014-2018 and who were working before their admission. Only patients with a percutaneous coronary intervention or coronary artery bypass grafting surgery procedure and ICD-10 codes I20-I25 as their main diagnosis or ICD-10 codes I21, I240, I248 or I249 as secondary diagnosis during an emergency admission were included. Exposure was defined as participation in cardiac rehabilitation (N = 15,742), and binary indicator of being at work in the last week of a given month were used as primary outcomes. Coarsened exact matching (CEM) of exposed and unexposed patients was used to reduce selection bias. Logistic regression models were applied on the matched population (N = 15,762). RESULTS: Less deprived and less comorbid patients were more likely to receive cardiac rehabilitation. CEM succeeded in arriving at a population where this selection was reduced and in this population we found that patients who received cardiac rehabilitation had a lower probability of returning to work after 3 months (OR 0.81, 95%CI: 0.77-0.84), a higher but insignificant probability after 6 (OR 1.02, 95%CI: 0.97-1.08), and a higher probability after 9 (OR 1.08, 95%CI: 1.02-1.15) and 12 months (OR 1.20, 95%CI: 1.13-1.28). CONCLUSIONS: Deprived and comorbid patients have lower use of cardiac rehabilitation. In a matched population where this bias is reduced, cardiac rehabilitation will increase the probability of returning to work.

Impact of diabetes on long-term all-cause re-hospitalization after revascularization with percutaneous coronary intervention.

PURPOSE: The purpose of the study was to investigate the incidence, cause and probability of re-hospitalization within 30 and 365 days after percutaneous coronary intervention (PCI) in patients with diabetes. METHOD: Between January 2010 and September 2014, 2763 patients with diabetes were treated with PCI at two Hospitals in Western Denmark. Reasons for readmission within 30 and 365 days were identified. RESULTS: Readmission risks for patients with diabetes were 58% within 365 days and 18% within 30 days. Reason for readmission was ischemic heart disease (IHD) in 725 patients (27%), and non-IHD-related reasons in 826 patients (31%). IHD-related readmission within 365 days was associated with female gender (OR 1.3, 95% CI: 1.1-1.5), and non-ST-segment elevation myocardial infarction, compared to stable angina at the index hospitalization (OR 1.3, 95% CI: 1.1-1.6). Among patients with diabetes, increased risk of readmission due to other reasons were age (OR 1.3, 95% CI: 1.2-1.5) and higher scores of modified Charlson Comorbidity index (CCI): CCI ≥3 (OR 3.6, 95% CI: 2.8-4.6). CONCLUSION: More than half of the patients with diabetes mellitus undergoing PCI were readmitted within 1 year. Comorbidities were the strongest predictor for non-IHD-related readmission, but did not increase the risk for IHD-related readmissions.

National survey of current practice and opinions on rehabilitation for intermittent claudication in the Danish Public Healthcare System.

Objective. International guidelines recommend rehabilitation including supervised exercise therapy in patients with Intermittent Claudication (IC), but knowledge of the implementation in clinical practice is limited. This study aims to investigate current practice and opinions on rehabilitation for patients with IC among vascular surgeons and rehabilitation departments in the municipalities and hospitals. Design. Three electronic cross-sectional surveys were distributed nationally to the Danish vascular surgeons (n = 131) and to rehabilitation departments in the municipalities (n = 92) and hospitals (n = 33). Results. The response rates were 70% among the vascular surgeons, 98% among the municipalities and 94% among the hospitals. Vascular surgeons utilize oral advice to exercise by self-administered walking, pharmacological treatment, and revascularization to improve walking distance in patients with IC. Currently, only 12% of the vascular surgeons referred to rehabilitation to improve walking distance, while almost all vascular surgeons (96%) would refer their patients to IC rehabilitation, if it was available. Only 14% of municipalities and none of the hospitals, who treat patients with IC, have a rehabilitation program designed specifically for patients with IC. However, 59% of the rehabilitation departments in the municipalities and 26% in the hospitals included patients with IC in rehabilitation program designed for other patient groups - mostly cardiac patients. There was consensus among the groups of respondents that future IC specific rehabilitation should include an initial conversation, supervised exercise therapy, smoking cessation, and patient education according to guidelines. Conclusion. Vascular surgeons support referral and participation in IC rehabilitation to improve walking distance in patients with IC. Despite some hospitals and municipalities included patients with IC in rehabilitation nearly all services fail to meet current guideline as specific services tailored to patient with IC is almost non-existent in Denmark. Our findings call for action for services to comply with current recommendations of structured, systematic rehabilitation for patients with IC.

Impact of exercise-based cardiac rehabilitation in patients with heart failure (ExTraMATCH II) on mortality and hospitalisation: an individual patient data meta-analysis of randomised trials.

AIMS: To undertake an individual patient data (IPD) meta-analysis to assess the impact of exercise-based cardiac rehabilitation (ExCR) in patients with heart failure (HF) on mortality and hospitalisation, and differential effects of ExCR according to patient characteristics: age, sex, ethnicity, New York Heart Association functional class, ischaemic aetiology, ejection fraction, and exercise capacity. METHODS AND RESULTS: Randomised trials of exercise training for at least 3 weeks compared with no exercise control with 6-month follow-up or longer, providing IPD time to event on mortality or hospitalisation (all-cause or HF-specific). IPD were combined into a single dataset. We used Cox proportional hazards models to investigate the effect of ExCR and the interactions between ExCR and participant characteristics. We used both two-stage random effects and one-stage fixed effect models. IPD were obtained from 18 trials including 3912 patients with HF with reduced ejection fraction. Compared to control, there was no statistically significant difference in pooled time to event estimates in favour of ExCR although confidence intervals (CIs) were wide [all-cause mortality: hazard ratio (HR) 0.83, 95% CI 0.67-1.04; HF-specific mortality: HR 0.84, 95% CI 0.49-1.46; all-cause hospitalisation: HR 0.90, 95% CI 0.76-1.06; and HF-specific hospitalisation: HR 0.98, 95% CI 0.72-1.35]. No strong evidence was found of differential intervention effects across patient characteristics. CONCLUSION: Exercise-based cardiac rehabilitation did not have a significant effect on the risk of mortality and hospitalisation in HF with reduced ejection fraction. However, uncertainty around effect estimates precludes drawing definitive conclusions.

Comprehensive cardiac rehabilitation: a cost assessment based on a randomized clinical trial.

OBJECTIVES: The costs of comprehensive cardiac rehabilitation are established and compared to the corresponding costs of usual care. The effect on health-related quality of life is analyzed. METHODS: An unprecedented and very detailed cost assessment was carried out, as no guidelines existed for the situation at hand. Due to challenging circumstances, the cost assessment turned out to be ex-post and top-down. RESULTS: Cost per treatment sequence is estimated to be approximately euro 976, whereas the incremental cost (compared with usual care) is approximately euro 682. The cost estimate is uncertain and may be as high as euro 1.877. CONCLUSIONS: Comprehensive cardiac rehabilitation is more costly than usual care, and the higher costs are not outweighed by a quality of life gain. Comprehensive cardiac rehabilitation is, therefore, not cost-effective.

Cardiac rehabilitation services in Denmark: still room for expansion.

AIM: European cardiologists agree that cardiac rehabilitation (CR) should be offered as an integrated part of cardiac care, and CR guidelines have been published. The authors aimed to ascertain the potential for expanding CR coverage at hospitals in Denmark. METHOD: A cross-sectional questionnaire study was conducted among all hospitals receiving acute cardiac patients (n = 67). The response rate was 79%, with no differences according to catchment area, number of beds, or geographical location. The hospitals were classified as having full CR if all core components (physical training, psychosocial support, dietary counselling, smoking cessation, and pharmaceutical risk factor management) were available during each of three phases: (I) in hospital; (II) outpatient; and (II) community-based services. RESULTS: Many hospitals offered one or more of the CR components during phases I and II: physical training (77%; 77%), psychosocial support (89%; 79%), dietary counselling (85%; 89%), smoking cessation (94%; 68%), and clinical control by a physician (100%; 93%). The content varied greatly. Full phase I CR was offered at 57% (95% confidence interval (95% CI): 44-70%) of the hospitals and 47% (95% CI: 34-60%) offered full phase II CR. Phase III CR was very rare (2% (95% CI: 0-6%). The numbers of patients receiving CR was not registered. CONCLUSION: Marked progress was made in the 1990s in implementing CR; nevertheless, the services are far from fully expanded. Denmark has great potential for improving CR services, as do most other European countries. CR activities need to be registered at Danish hospitals.

Hospital variation in mortality after first acute myocardial infarction in Denmark from 1995 to 2002: lower short-term and 1-year mortality in high-volume and specialized hospitals.

BACKGROUND: This study used linked data from the National Hospital Registry to determine the factors that contribute to differences between hospitals in all-cause mortality after first acute myocardial infarction (AMI) between 1995 and 2002. METHODS: The study included 64,321 patients with their first admission for AMI between 1995 and 2002 and surviving the day of admission. Multilevel logistic regression was used to determine the relationships between regional and hospital characteristics and 28-day and 365-day mortality after adjusting for individual characteristics, period, and medical history. RESULTS: Tertiary cardiac care centers (odds ratio [OR], 0.80; 95% confidence interval [CI], 0.67-0.96) and main regional hospitals (OR, 0.90; 95% CI, 0.80-0.99) had improved 28-day mortality compared with local hospitals. A 2-fold increase in annual total MI volume decreased 28-day mortality (OR, 0.91; 95% CI, 0.87-0.94) and 365-day mortality (OR, 0.95; 95% CI, 0.91-0.98). Differences between hospitals were more substantial for short-term mortality, such that patients were about twice as likely to die within 28 days in hospitals with the worst performance versus those with the best performance. Higher regional AMI incidence was associated with lower mortality before 2000; this disappeared after 2000. Other regional contextual characteristics had very modest effects on mortality. CONCLUSIONS: Type of hospital, and especially total MI volume at the hospital level, were significantly associated with mortality after AMI. Individual hospitals varied substantially in both short- and long-term mortality.
