Background . Cardiac rehabilitation (CR) in China has not been widely adopted for a variety of reasons, including healthcare provider (HCP)s' lack of awareness and beliefs. Objective . To explore HCP's perceptions of CR in China. Methods . An exploratory, sequential design was used in this mixed-methods study. Face-to-face semi-structured interviews were performed; this was followed by a cross-sectional survey. Setting . The interviews were conducted in a university-affiliated hospital and a rehabilitation hospital in Shanghai. The survey was conducted in the cardiac departments of primary, secondary, or tertiary hospitals in Shanghai or Yunnan Province, China. Participants . Saturation was achieved upon interviewing 13 HCPs (5 doctors, and 8 nurses). A total of 610 HCPs (185 doctors [30.5%], 417 nurses [68.8%]) completed the survey. Results . Analysis of the interviews revealed 4 themes: the perceived value of CR, the need for pro-CR policy, variability in CR awareness, and obstacles to CR delivery. HCP approaches to the treatment of patients with cardiac conditions did not universally include exercise training (only approximately 60% of HCPs), or all other recommended domains of secondary prevention, and assessment of the major risk factors was quite low. Familiarity with CR was moderate (48.7%). HCPs perceived that philosophies of Traditional Chinese Medicine (TCM) were highly compatible with, and could add value to, CR. HCP approaches to secondary preventive care and CR perceptions varied significantly according to their highest level of education, clinical profession, job seniority, type of hospital where they worked, whether the hospital had a CR program and the hospital's location. Conclusion . HCPs recognize the value of CR, particularly considering secondary preventive care practices were not comprehensive. Education is needed to improve HCPs CR awareness.
