The goal of this open-label cluster-randomized effectiveness-implementation hybrid trial is to study whether a) audit and feedback of cardiac rehabilitation service delivery within a national quality registry and b) structured implementation support can improve center-level adherence to guidelines and short and long-term patient-level outcomes.
Administering secondary prevention via structured cardiac rehabilitation (CR) programs for patients who have suffered a myocardial infarction (MI) reduces mortality and morbidity and improves quality of life. Still, treatment goal achievement at patient-level and service delivery at center-level are sub-optimal and there is a large variation in program structure and delivery at center-level.
Using an open-label cluster-randomized effectiveness-implementation hybrid trial design, the primary objective of this study is to prospectively evaluate whether a) audit and feedback of CR processes and structures within the national cardiac registry SWEDEHEART and b) supporting CR centers in implementing CR guidelines can increase center-level guideline adherence. The secondary objectives are the following:
All CR centers in Sweden (approximately 75 centers) will be offered participation in the study. Collectively these centers attend to approximately 8000 patients/year. Patient-level outcome data will be retrieved from national registries.

| Audit and feedback through a quality registry | Other | Centres answer CR process and structure variables through the SWEDEHEART registry every six months for three years. Feedback will be accessible online and through annual reports, enabling comparisons with own prior and other centres´ results. |
| Measure | Description | Time Frame |
|---|---|---|
| Adherence score | The adherence score reflects center-level adherence to CR processes and structures as recommended in national guidelines on secondary prevention. The score is derived from 39 variables capturing guideline-directed CR structure and processes collected on center-level through the national cardiac registry SWEDEHEART. The score ranges from 0 (worst) to 39 (best). | 3 years |
| Measure | Description | Time Frame |
|---|---|---|
| Blood pressure target attainment | For patients <70 years of age <130/80 mmHg and for patients ≥70 years <140/80 mmHg (yes/no) | One year |
| Systolic blood pressure | Continuous variable in mmHg |

The data to be used in this study is based on the SWEDEHEART registry. Access to data from the registry needs to be applied for and third-party data usage is not allowed, irrespective of whether the data contain potentially identifying or sensitive data or not. Instead, given ethical study approval from the Swedish Ethical Review Authority, access to SWEDEHEART data can be applied for from the Uppsala Clinical Research Center (UCR) in Sweden. Further information can be found on the UCR www.ucr.uu.se/en/ and Swedish Ethical Review Authority etikprovningsmyndigheten.se/ websites.

| Implementation support | Other | On-site support to implement guidelines on secondary prevention applying practice facilitation - a multifaceted approach carried out by CR experts who enable personnel at intervention centres to address and overcome challenges in implementing guidelines. |
|
| One year |
| Low-density lipoprotein cholesterol target attainment | <1.4 mmol/L (yes/no) | One year |
| Low-density lipoprotein cholesterol | Continuous variable in mmol/L | One year |
| Self-reported quality of life | Measured using EuroQoL-Visual Analogue Scale (EQ-VAS) - a vertical visual analogue scale with a range of values between 100 (best imaginable health) and 0 (worst imaginable health) | One year |
| Self-reported smoking status | Never smoker, former smoker (>1 month) or current smoker | One year |
| Self-reported dietary habits | Dietary habits are assessed by self-report through four questions covering intake of fruit, vegetables, fish and sweets. Each question gives points ranging from 0 (worst) to 3 (best), summing up to a total score of 0-12 points. | One year |
| Self-reported physical activity | Number of days during the last week the patient has been physically active for a minimum of 30 minutes (at least 10 minutes at a time) with activity causing shortness of breath and a slightly increased pulse, corresponding to a brisk walk. Permissible values can thus range from 0 days (worst) to 7 days (best). | One year |
| Attendance in an exercise-based CR programme | Attended for at least 3 months (yes/no) | One year |
| Major adverse cardiovascular events (MACE) | A composite endpoint of the following events:
| Five years |
| Total mortality | Death from any cause. | Five years |
| Acceptability of the implementation support | Acceptability reflects the degree to which the intervention is perceived as being feasible, desirable, and appropriate by stakeholders (healthcare providers, i.e., the CR team and organizational leaders) and the level of preparedness of the organization to adopt the intervention. Acceptability will be assessed through semi-structured interviews with healthcare personnel at centers subject to the implementation intervention. Interview guides, allowing for flexibility in terms of order and form of questions and topics, using mainly open-ended and neutral questions will be developed. The exact number of interviews will be decided on after start of the study and will continue until a) no new concepts or categories are identified and b) when there is no need for further elaboration of these. | Assessed at the time of implementation |
| Adoption of the implementation support | Adoption determines the extent to which the intervention is used in practice. Adoption of the implementation support will be assessed through semi-structured interviews with healthcare personnel at centers subject to the implementation intervention. | Assessed six months after the implementation support has been provided |
| Fidelity of the implementation support | Fidelity reflects the degree to which the implementation used in practice adheres to the original design of the intervention. Fidelity will be assessed through semi-structured interviews with healthcare personnel at centers subject to the implementation intervention. | Assessed six months after the implementation support has been provided |
| Implementation cost and cost effectiveness | Reflects resources required to implement the intervention, including the cost of material, staff, and any other expenses incurred as a result of the implementation of the intervention. Based on the cost estimates and the effect of the implementation assistance on patient outcomes, the economic evaluation will then be able to calculate cost-effectiveness ratios. | Assessed at the time of implementation |
