Point of care ultrasound knowledge attitudes and practices among emergency and ICU healthcare providers

This cross-sectional study assessed point-of-care ultrasound (PoCUS) knowledge, attitudes, and practices (KAP) among 451 Intensive Care Unit (ICU) and Emergency providers in Xinjiang, China. Results showed adequate knowledge (median score: 12/14) but suboptimal attitudes (19/40) and infrequent practice (25/45). Over half of participants had rarely used PoCUS in the last year, and nearly 40% felt single-course training was insufficient. Multivariate analysis identified higher knowledge (OR = 1.259) and attitude (OR = 1.168) scores as positive predictors of practice, while nursing occupation was a negative predictor (OR = 0.490). A structural equation model confirmed that knowledge and attitude directly influenced practice, and knowledge also indirectly influenced practice through attitude. In conclusion, a significant knowledge-application gap exists, driven by negative attitudes and practical barriers despite sufficient provider knowledge.
