This study aimed to assess the impact on clinical diagnosis, clinician confidence and management. Ultrasound has been shown to have utility in patients admitted to intensive care and emergency; however, utility in a ward setting is unknown. <\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p> Prospective cohort study. <\/jats:p><\/jats:sec><jats:sec><jats:title>Setting<\/jats:title><jats:p> Tertiary hospital in Melbourne, Australia. <\/jats:p><\/jats:sec><jats:sec><jats:title>Participants<\/jats:title><jats:p> 50 patients with acute respiratory failure requiring admission to an intermediate care unit. <\/jats:p><\/jats:sec><jats:sec><jats:title>Main outcome measures<\/jats:title><jats:p> (1) Change in clinical diagnosis or additional clinical diagnosis following thoracic ultrasound.

Diagnostic confidence was increased in 44%, and the treating clinician altered the management plan in 30% as a result of the ultrasound. Ultrasound was particularly useful in clarifying the diagnosis in patients with multiple initial diagnoses, reducing to a single diagnosis in 69%. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> Thoracic ultrasound has clinical utility in non-intubated adults with acute respiratory failure managed outside intensive care settings. It changed aetiological diagnosis, increases diagnostic confidence and altered clinical management in one out of three patients scanned. Our results suggest extended utility of thoracic ultrasound in acute respiratory failure to a broader context outside the intensive care unit population. <\/jats:p><\/jats:sec>","DOI":"10.1177\/2054270417695055","type":"journal-article","created":{"date-parts":[[2017,5,2]],"date-time":"2017-05-02T09:28:13Z","timestamp":1493717293000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["A prospective cohort study of thoracic ultrasound in acute respiratory failure: the <i>C<sub>3<\/sub>PO<\/i> protocol"],"prefix":"10.1177","volume":"8","author":[{"given":"Peter D","family":"Wallbridge","sequence":"first","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, University of Melbourne, Parkville, Victoria 3050, Australia"},{"name":"Department of Respiratory and Sleep Medicine, Royal Melbourne Hospital, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Simon A","family":"Joosten","sequence":"additional","affiliation":[{"name":"Department of Respiratory and Sleep Medicine, Royal Melbourne Hospital, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liam M","family":"Hannan","sequence":"additional","affiliation":[{"name":"Department of Respiratory and Sleep Medicine, Royal Melbourne Hospital, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel P","family":"Steinfort","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, University of Melbourne, Parkville, Victoria 3050, Australia"},{"name":"Department of Respiratory and Sleep Medicine, Royal Melbourne Hospital, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Irving","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, University of Melbourne, Parkville, Victoria 3050, Australia"},{"name":"Department of Respiratory and Sleep Medicine, Royal Melbourne Hospital, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Goldin","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, University of Melbourne, Parkville, Victoria 3050, Australia"},{"name":"Department of Respiratory and Sleep Medicine, Royal Melbourne Hospital, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Hew","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, University of Melbourne, Parkville, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,5,2]]},"reference":[{"key":"bibr1-2054270417695055","doi-asserted-by":"publisher","DOI":"10.1378\/chest.118.4.1100"},{"key":"bibr2-2054270417695055","doi-asserted-by":"publisher","DOI":"10.1186\/cc4926"},{"key":"bibr3-2054270417695055","unstructured":"Hannan LH and Howard ME.
