Reviewer's Responses to Questions

Comments to the Author

1. Does the manuscript provide a valid rationale for the proposed study, with clearly identified and justified research questions?

The research question outlined is expected to address a valid academic problem or topic and contribute to the base of knowledge in the field.

Reviewer #1: Yes

Reviewer #2: Yes

********** 

2. Is the protocol technically sound and planned in a manner that will lead to a meaningful outcome and allow testing the stated hypotheses?

The manuscript should describe the methods in sufficient detail to prevent undisclosed flexibility in the experimental procedure or analysis pipeline, including sufficient outcome-neutral conditions (e.g. necessary controls, absence of floor or ceiling effects) to test the proposed hypotheses and a statistical power analysis where applicable. As there may be aspects of the methodology and analysis which can only be refined once the work is undertaken, authors should outline potential assumptions and explicitly describe what aspects of the proposed analyses, if any, are exploratory.

Reviewer #1: Yes

Reviewer #2: Yes

********** 

3. Is the methodology feasible and described in sufficient detail to allow the work to be replicable?

Descriptions of methods and materials in the protocol should be reported in sufficient detail for another researcher to reproduce all experiments and analyses. The protocol should describe the appropriate controls, sample size calculations, and replication needed to ensure that the data are robust and reproducible.

Reviewer #1: Yes

Reviewer #2: Yes

********** 

4. Have the authors described where all data underlying the findings will be made available when the study is complete?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception, at the time of publication. The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes

********** 

5. Is the manuscript presented in an intelligible fashion and written in standard English?

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

Reviewer #1: Yes

Reviewer #2: Yes

(Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: thanks a lot for your manuscript that provide a valid rationale for the proposed study --

Reviewer #2: Well described feasibility study.

There are few things need to be considered:

- Some abbreviation are mentioned in the manuscript without previous introduction such as NGO.

- Why in the inclusion criteria, patient post CABG are not included?

- The model created which include follow up by phone calls, from my point of view is a little bit outdated, since nowadays we are experiencing advancement in Telerehabilitation or remote monitoring of the patients. Has this been considered by the authors?

- Most of the outcome measures are relatively subjective and does not reflect the physiological benefits of attendance and adherence to the program.

- There is a need to identify the phase of cardiac rehabilitation provided at each stage of the model suggested.

Reviewer #1: thanks a lot for your manuscript that provide a valid rationale for the proposed study --

Reviewer #2:

Comment 6:

- Some abbreviation are mentioned in the manuscript without previous introduction such as NGO.

Our response

On page 9, line 142-143, MRC has been corrected to “UK Medical Research Council (MRC)”

On page 9, line 144-145 NGO has been corrected to “a non-governmental organization”

On page 10, lines 182-183, we have added “randomized controlled trial (RCT)-component”

On page 13, lines 249-250, we have added “The Victorian Health Promotion Foundation

(VicHealth)”

On page 20, line 404, we have added “the 12-Item Short Form Survey (SF-12)”

On page 28, lines 594-595, we have added “Chronic obstructive pulmonary disease (COPD)”

Comment 7

- Why in the inclusion criteria, patient post CABG are not included?

Our response

Post coronary artery bypass graft (CABG) patients are included in the group diagnosed with ischemic heart disease just like patients who have undergone PCI (percutaneous coronary intervention).

Comment 8

- The model created which include follow up by phone calls, from my point of view is a little bit outdated, since nowadays we are experiencing advancement in Telerehabilitation or remote monitoring of the patients. Has this been considered by the authors?

Our response

Telerehabilitation or remote monitoring of patients is currently not an option in the Cardiac Outpatient Clinic at Hvidovre Hospital and at the Rehabilitation Center Albertslund. Using telerehabilitation requires introduction and guidance to the patients to enable this practice. In general, telerehabilitation is used in the treatment and monitoring of diseases. We consider phone calls an appropriate, easily accessible, and low-cost method to follow up on the patients’ physical activity level in this study which primarily focuses on participation in a cross-sectoral rehabilitation program and long-term physical activity.

Comment 9

- Most of the outcome measures are relatively subjective and does not reflect the physiological benefits of attendance and adherence to the program.

Our response

We agree that increased physical activity level among the participants can have a physiological effect and that it, therefore, could be relevant to add objective measures reflecting the physiological benefits. However, the interventions in this study focus on increasing rehabilitation participation rates and long-term physical activity levels rather than improving physiological benefits by increasing the amount of exercise or intensity of the activity. Therefore, we have chosen not to measure objective biological markers of physiological effects of participation in rehabilitation. Although most of our outcome measures are self-reported, we also measure participation through registration by partners.

Comment 10

- There is a need to identify the phase of cardiac rehabilitation provided at each stage of the model suggested.

Our response

According to the Danish Cardiac Rehabilitation Program, cardiac rehabilitation includes three phases:

• Phase one is the acute phase with hospital admission, clarification of diagnosis, and treatment (medical and/or surgical). The duration is days.

• Phase two is the period after discharge from the hospital, patients are offered further treatment and initiation of a rehabilitation program for either 12 weeks in the hospital, 12 weeks in the municipality, or 6 weeks in the hospital and 6 weeks in the municipality. The duration is weeks to months.

• Phase three is a further follow-up, control, and continued medical treatment by a general practitioner and rehabilitation efforts in the municipality. The duration is life-long.

Based on these phases, the interventions in this study is placed in phases two and three. We have, however, chosen not to define the different phases and stages of cardiac rehabilitation in our rehabilitation model, as we consider our rehabilitation model as one coherent course with individual options. Our participants can select or deselect some of the rehabilitation offers during the program. They can choose, for example, to go directly from the hospital to a sports association in civil society. Since all participants do not have to follow the same rehabilitation path, we believe that a division into phases is not appropriate in the current study.

In addition

We have corrected the definition of participation in rehabilitation in the abstract on page 5, lines 78-80 from

“The primary outcome: rehabilitation participation (attending ≥ two activities: pro-active counselling, patient education, smoking cessation, dietary counseling, physical exercise, local sports association activity) and reaching at least 50% attendance.”

to:

“The primary outcome: rehabilitation participation (attending ≥ two activities: patient education, smoking cessation, dietary counseling, and physical training) and reaching at least 50% attendance.”

The reason for the correction is that pro-active counselling and local sports association activity by mistake was written in the definition.
