To assess the effect of speech recognition on hospital-wide radiology report availability in a university hospital setting with an integrated PACS/RIS system and digital image and report distribution.

Prospectively, reporting times (RT) from 12 radiologists of all educational levels during daily routine were documented for 240 cases of x-ray (CR) and computed tomography (CT) each. Reports were created with conventional (CD) and speech recognition dictation (SR) respectively. For the 240 cases, individual reporting time (i.e. image reading plus dictation time) using CD and SR was measured. Time-stamps of image acquisition (entry of first image into PACS) and first availability of the associated written report in RIS/HIS were documented. The time interval between both time-stamps was addressed as report turnaround time (RTT). In retrospect, RTT for 11/02-02/03 (only conventional dictation with transcription) and 11/03-02/04 (remote or online SR with transcriptionist (TC) or self correction (SC)) were calculated from the PACS/RIS database. RTT were classified in 3 categories: I) reports delivered in less than one day. II) reports delivered in 5 hours or less. III) reports delivered in less than 1 hour.

Prospectively the mean RT was 74s /58s /49s for conventional dictation/speech recognition (TC/SC) per CR case and 194s /231s /165s for CD/SR (TC/SC) per CT case. The mean RTT was 21,1h /25,1h /8,9h for CR with CD/SR (TC/SC) and 23,8h /29,6h /7,6h for CT with CD/SR (TC/SC). In retrospect, 37898/ 39680 datasets were analysed. The number of reports delivered in less than one day was 3485/11453, delivered in 5 hours or less was 2410/9710 and delivered in less than 1 hour was 352/2050 for 2002-03/2003-04. This corresponds to an increase of reports delivered in less than one day of 19,7% of all reports, delivered in 5 hours or less by 18,1%, delivered in less than 1 hour by 4,2%.

The implementation of speech recognition with full technical and workflow integration into the existing PACS/RIS radiology environment leads to a significant reduction of mean report turnaround time when online speech recognition and radiologist self-correction is used.
