Background. Healthcare students (HCS) and healthcare practitioners (HCP) have an important role in addressing climate change (CC). This study aims to review original research on knowledge, perception, attitude and practice of CC among HCS and HCP. Methods. Two databases, PubMed and Google Scholar, were searched for original research articles using specific keywords. Studies were also obtained by examining the reference list of included articles. Only English language publications from 2008 to 2024 were included. Study quality was assessed using suitable checklists. Results. Sixty-six studies were included. Most were published during the period from 2017 to 2024, used quantitative methods, and were conducted in developing nations. The United States (US) published the highest number. Most studies were conducted among nursing and medical students, did not include an intervention, and were of good quality. Among HCS and faculty in developed nations, knowledge was good but practice required improvement. Among developing countries, knowledge ranged from poor to moderate and there were deficiencies in practice. Conclusions. Respondents wanted sessions on CC. More studies are required. Some studies had methodological limitations. Studies from non- or under-represented regions and countries are required.
