Do picture archiving and communication systems improve report turnaround times?

Abstract

Radiology departments are beginning to embrace new technologies to decrease operating budgets and improve services. One of these technologies is the picture archiving and communication system (PACS). PACS, through immediate availability of images to the radiologist, promises to decrease turnaround times of reports to the clinician. The purpose of this study was to determine if this technology actually decreases the time for referring clinicians to receive reports generated by the radiologist. The time to provide a preliminary report by a resident and time to finalize this report by a board-certified radiologist was retrospectively obtained for 6,022 abdominal and pelvic computed tomography (CT) scans over two 1-year periods from March 1, 1997 to March 1, 1998 and from March 1, 1998 to March 1, 1999. During the first year, interpretation was conducted using hard-copy film and during the second using PACS. In both 1-year periods, MedSpeak voice recognition software (IBM, White Plains, NY) was employed for dictation. The average time for a preliminary report for a abdominal and pelvic CT, dictated by a resident or fellow, to be available in alphanumeric form on the hospital information system using hard-copy film was 3.73 days. The installation of a PACS system decreased this turnaround time to 0.56 days, representing an 85.0% improvement. The time to availability of final reports, ie, signed by board-certified staff radiologists, was 5.49 days in the hard-copy interpretation subset and 5.97 days in the PACS subset. The addition of PACS into an academic gastrointestinal radiology division improves availability of alphanumeric preliminary reports of abdominal and pelvic CTs on the hospital information system (HIS), dictated by a resident or fellow, by 85.0%. There was no impact with a PACS on the time to final sign reports by a staff board certified radiologist as signing patterns remained relatively constant over the two interpretation formats.
