2.1 Search Strategy & Data Sources
The search used the next related terms: Population – CABG patients;
Interventions –CRP; Comparators – routine standard care or treatment,
which is usually drugs and general instruction; Outcomes – HRQoL and
physiological variables.
First, in this study, a comprehensive
search of electronic databases was conducted including PubMed, EBSCO
host, Springer Link, Science direct, google scholar, and Medline from
the year 2010-2021. Our search keywords were; coronary artery bypass
graft or CABG, health-related quality of life OR HRQOL, physiological
outcomes, cardiac rehabilitation program OR CRP, cardiac rehabilitation
intervention, randomized control trial OR RCT,
Experimental/interventional, and Quasi-experimental. (See Supplementary
File. 2: Electronic search strategy).
The search was limited to adult populations, English language,
inpatients and outpatient settings, but we omitted articles that
involved CABG patients who are mentally incompetent, such as delirium,
confusion, or anxiety disorders; and patients with the uncontrolled
glycemic condition and metabolic disturbances, uncontrolled HTN,
neurological or muscular disorders, and uncontrolled cardiac arrhythmia
(which can be detected from patients’ files), as patients with these
conditions have more complications and these conditions itself affect
HRQOL. Summary of the studies’ inclusion and exclusion criteria are in
