Knowledge, attitude, and practice regarding sarcopenia: a survey between orthopedic and geriatric professionals in China

Background In elderly patients with fractures, sarcopenia impairs recovery and even increases mortality. Both orthopedic and geriatric professionals are at the forefront of treating sarcopenic patients with fractures. However, it is not clear to what extent they have knowledge and skills to diagnose and treat sarcopenia. Aims This study aimed to analyze and compare knowledge, attitude, and practice regarding sarcopenia between orthopedic and geriatric professionals. Methods An online cross-sectional survey was conducted in June 2022 targeting professionals in orthopedic and geriatric departments in two largest tertiary general hospitals in Taizhou, southeastern China. Results on knowledge, attitude, and practice of sarcopenia were analyzed. Variables with significance were then included in a stepwise multiple linear regression analysis. Results A total of 220 professionals, 176 from orthopedic departments and 44 from geriatric departments, participated in this study. Orthopedic professionals scored lower than geriatrics in knowledge, attitude and practice ( P < 0.001). The attitude score was high in both orthopedic and geriatric professionals. Stepwise multiple linear regression analysis showed that participants who had contact with sarcopenia patients had higher knowledge score ( β = 1.941, P < 0.001); participants who had attended sarcopenia training in the past 6 months ( β = 4.305, P < 0.001) had higher practice score. Discussion Orthopedic professionals have deficiencies in the screening and diagnosis of sarcopenia. Improving the knowledge and training of professionals can strengthen practice. It is necessary to formulate diagnostic criteria and improve practice of sarcopenia through training. Conclusion Orthopedic professionals had limited knowledge and practice regarding sarcopenia compared with geriatric professionals. To improve sarcopenia practice, the use of diagnostic tools to formally diagnose sarcopenia and regular training on sarcopenia should be encouraged.
