Description of intervention(s) / exposure
The aim of this study is first to translate and cross-culturally adapt the "Cardiac Rehabilitation Barriers Scale" (CRBS) to Czech (CRBS-CZE), and then psychometrically validate the translation and check internal reliability.
The main aim is to identify the barriers which prevent patients from entering the II. phase of cardiac rehabilitation (CR). We need to compare these barriers between enrollers and non-enrollers. The percentage of completers and non-completers must be determined, and finally we will compare the barriers affecting adherence and completition of ambulatory training program.

Study will take place in the Internal Cardiology Clinic of University Hospital Brno - coronary unit, care center, standard department. The research group will be made up of coronary artery disease (CAD) patients meeting the criteria for the II. phase of CR.

Main data collection method is filling the CRBS-CZE.
Patients indicated to the II. phase of CR will be educated in training program and CRBS-CZE through which we find their interest in participation. Physiotherapist will have a conversation with each patient and obtains necessary data (sample characteristics). Then immediatelly (4-12 weeks before CR commencement) each participant will fill in the CRBS-CZE individually (total approximate duration 30 mins).
The standard CR program involves 3 trainings a week for 3 months. The patients attending at least one training session will be considered enrollers. The rest of them will be qualified as non-enrollers. Subsequently we will evaluate the barriers, compare among the enrollers and non-enrollers, prospectively among completers and non-completers. Furthermore, we will express the adherence of training program and percentage of total completition.

CRBS original
(I did not attend a cardiac rehabilitation program, or if I did attend, I missed some sessions because:)
CRBS_01… of distance
CRBS_02… of cost
CRBS_03… of transportation problems
CRBS_04… of family responsibilities
CRBS_05… I didn’t know about CR
CRBS_06… I don’t need CR
CRBS_07… I already exercise at home, or in my community
CRBS_08… severe weather
CRBS_09… I find exercise tiring or painful
CRBS_10… travel
CRBS_11… of time constraints
CRBS_12… of work responsibilities
CRBS_13… I don’t have the energy
CRBS_14… other health problems prevent me from going
CRBS_15… I am too old
CRBS_16… my cardiologist or thoracic surgeon did not feel it was necessary
CRBS_17… many people with heart problems don’t go, and they are fine
CRBS_18… I can manage my heart problem on my own
CRBS_19… I think I was referred, but the rehab program didn’t contact me
CRBS_20… it took too long to start the outpatient program after referral
CRBS_21… I prefer to take care of my health alone, not in a group

Defined population
Statistical methods / analysis
Data will be password-protected so that only research team can access it. Personal information will be processed and backed up according to currently valid General Data Protection Regulations (GDPR).

We want to capture the date within one year to claim as many participants as possible to reach the most objective description of the situation on our workplace. There are around 1.000 patients hospitalized in the Internal Cardiology Clinic. The expected number of research group patients is between 300 and 600 respondents.

To evaluate the internal reliability of CRBS-CZE we will use Cronbach’s alpha. We will also check factor structure with factor analysis. Data will be processed via common statistical measures – mean, standard deviation. To compare the enrolment barriers and total adherence we will use a t-test.

Brief summary
Ambulatory training program is an effective method of secondary prevention in patients with CAD. Unfortunately, utilization of CR program is low. The enrolment barriers to CR in the Czech Republic are still unknown or not properly described. Through this study we want to refer to current situation in our region. Results will be used to identify ways to help patients overcome barriers to CR utilization.
