Four main themes emerged: (1) There are important LUS despite operator dependence, (2) enhances patient clinician experience, (3) Investment time learn perform is barrier but yields improved efficiency for system (4) Mandated training use may be necessary achieve broad as monetary incentives less effective. perceived benefits patients, clinicians systems, significant experience scarcity by hospitalists.
