Knowledge level of cardio-oncology in oncologist and cardiologist: A survey study in China

Background: With the rapid development of the field of cardio-oncology, it has been recognized as an important medical area to improve the healthcare quality of cancer patients with cardiac complications. In this study, we investigated the knowledge level of cardio-oncology of oncologists and cardiologists in China. Methods: A structured questionnaire survey was conducted during 30th September, 2018 to 3rd December, 2019. Questionnaires were given to oncologists and cardiologists randomly selected. A general linear model was used to explore the significant factors associated with the knowledge level. Results: In total, 973 responses were finally solicited and included in the analysis. Only 3 respondents reached the full marks. Results of knowledge level of cardio-oncology in China were not found satisfactory. The knowledge level was better in respondents with a cardiology background (P-value =0.001), worked in the higher-level hospital (P-value =0.01), from the east or west region of mainland China (P-value <0.001), at a high position of doctor (Chief doctor, P-value =0.009), with full awareness of cardio-oncology (P-value <0.001) and favorable attitude toward cardio-oncology development (P-value <0.001). Conclusions: Our survey suggested that the demands of cardio-oncology service in China was huge but the low level of knowledge on cardio-oncology was alarming. Strong supports are needed to improve the dedicated education of cardio-oncology in China
