Data Collection
Independent of previous , the physician performing the PU entered
findings into an electronic data collection tool after leaving the
patient’s room. Relevant clinical data were abstracted from the
electronic health record by a research nurse. A final diagnosis for each
patient’s ARF was determined via review of clinical notes, formal
imaging, laboratory values, and the care team’s final diagnosis after
discharge which was conducted by study physicians who did not perform
the ultrasound and were blinded to results.
