{"pk":16296,"title":"Accuracy of ED Bedside Ultrasound for Identification of Gallstones: Retrospective Analysis of 575 Studies","subtitle":null,"abstract":"Study Objective: To determine the ability of emergency department (ED) physicians to diagnose cholelithiasis with bedside ultrasound. Methods: ED gallbladder ultrasounds recorded over 37 months were compared to radiology ultrasound interpretation. Results: Of 1,690 ED gallbladder ultrasound scans performed during this period, radiology ultrasound was performed in 575/1690 (34%) cases. ED physician bedside interpretation was 88% sensitive [95% CI, 84-91] and 87% specific [95% CI, 82-91], while positive predictive value (PPV) was 91% [88- 94%] and negative predictive value (NPV) was 83% [78-87%], using radiology interpretation as the criterion reference. Conclusion: ED physician ultrasound of the gallbladder for cholelithiasis is both sensitive and specific.","language":"en","license":{"name":"none","short_name":"none","text":"","url":"http://google.com"},"keywords":[{"word":"ultrasound"},{"word":"gallbladder"},{"word":"gallstones"},{"word":"Bedside"},{"word":"ED"}],"section":"Article","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0wx099bq","frozenauthors":[{"first_name":"William","middle_name":"","last_name":"Scruggs","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"},{"first_name":"J","middle_name":"Christian","last_name":"Fox","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"},{"first_name":"Brian","middle_name":"","last_name":"Potts","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"},{"first_name":"Alexander","middle_name":"","last_name":"Zlidenny","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"},{"first_name":"Joanne","middle_name":"","last_name":"McDonough","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"},{"first_name":"Craig","middle_name":"L","last_name":"Anderson","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"},{"first_name":"Jarrod","middle_name":"","last_name":"Larson","name_suffix":"","institution":"University of California, Irvine","department":"None"},{"first_name":"Graciela","middle_name":"","last_name":"Barajas","name_suffix":"","institution":"University of California, Irvine","department":"None"},{"first_name":"Mark","middle_name":"I","last_name":"Langdorf","name_suffix":"","institution":"University of California, Irvine School of Medicine","department":"None"}],"date_submitted":"2007-09-20T07:00:00Z","date_accepted":"2007-09-20T07:00:00Z","date_published":"2008-01-01T08:00:00Z","render_galley":null,"galleys":[{"label":"","type":"pdf","path":"https://journalpub.escholarship.org/westjem/article/16296/galley/8197/download/"}]}
