Lung ultrasonography was the most frequently performed exam (44%), followed by focused echocardiography (36%) and abdominal or vascular ultrasonography (20%). The increase in POCUS activity was associated with a parallel reduction in radiological ultrasonography and echocardiography. This result, while significant, was modest. After adjustment for the number of hospitalizations and CT scan requests, POCUS use was independently associated with decreased reliance on radiological ultrasonography (\n                      <jats:italic>\u03b2<\/jats:italic>\n                      \u2009=\u2009\u22120.10, 95% CI \u22120.15 to \u22120.05,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u2009.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The use of POCUS in internal medicine has steadily increased over the past 5 years and appears to provide significant diagnostic value.
