a Procedural POCUS applications and their perceived utility to general pediatricians. Pediatricians were asked the question “Which of the following procedural applications would be the most useful to you in your clinical practice?” They rated the following procedural applications on a 5 point Likert scale, (where 1 = I would never use this 2 = somewhat useful 3 = useful 4 = very useful 5 = extremely useful): abscess drainage, bladder volume measurement (i.e. prior to cath), peripheral vascular access, foreign body removal, lumbar puncture (including post-LP hematoma), arterial vascular access, Central vascular access, arthrocentesis. Note that the majority of respondents to this question were not formally trained in POCUS. b Diagnostic POCUS applications and their perceived utility to general pediatricians. Pediatricians were asked the question “Which of the following diagnostic applications would be the most useful to you in your clinical practice?” They rated the following diagnostic POCUS applications on a 5-point Likert scale (where 1 = I would never use this 2 = somewhat useful 3 = useful 4 = very useful 5 = extremely useful): skin and soft tissue (cellulitis or abscess), neck (lymphadenopathy vs abscess vs mass), advanced abdominal (appendicitis, intussusception, hypertrophic pyloric stenosis, cholecystitis), constipation (transrectal diameter to assess rectal stool burden), lung (pneumothorax, pneumonia, bronchiolitis, pleural effusion/empyema), genitourinary (bladder volume, hydronephrosis), foreign bodies (soft tissue), basic abdominal (abdominal free fluid), musculoskeletal (long bone and clavicle fractures, skull fractures, joint effusion), transabdominal pelvic (early pregnancy detection, IUD placement confirmation), focused cardiac exam (pericardial effusions, global cardiac function), optic nerve measurement (papilledema). Note that the majority of respondents to this question were not formally trained in POCUS
