Toward more user-friendly electronic endoscopy information systems: role of accessories

New report preparation system for endoscopic procedures using speech recognition technology

BACKGROUND AND STUDY AIMS

 We developed a new reporting system based on structured data entry, which selectively extracts only endoscopic findings from endoscopists' oral statements and automatically inputs them into appropriate columns in real time during endoscopic procedures.

METHODS

 We compared the time for endoscopic procedures and report preparation (ER time) by using an esophagogastroduodenoscopy simulator in three groups: one preparing reports using a mouse after endoscopic procedures (CE group); a second group preparing reports by using voice alone during endoscopic procedures (SR group); and the final group preparing reports by operating the system with a foot switch and inputting findings using voice during endoscopic procedures (SR + FS group). For the SR and SR + FS groups, we identified the recognition rates of the speech recognition system.

RESULTS

 Mean ER times for cases with three findings each were 162, 130 and 119 seconds in the CE, SR and SR + FS groups, respectively. The mean ER times for cases with six findings each were 220, 144 and 128 seconds, respectively. The times in the SR and SR + FS groups were significantly shorter than that in the CE group ( P  < 0.017). The recognition rate of the SR group for cases with three findings each was 98.4 %, and 97.6 % in the same group for cases with six findings each. The rates in the SR + FS group were 95.2 % and 98.4 %, respectively.

CONCLUSION

 Our reporting system was demonstrated to allow an endoscopist to efficiently complete the report in real time during endoscopic procedures.

Endoscopic electronic medical record systems

EEMR systems have become an integral part of the daily operation of many endoscopy units. Systems have evolved from simple endoscopy report generators to sophisticated endoscopy unit managers. Newer features of these systems may improve patient care and enhance endoscopy unit efficiency and productivity, but further studies are needed. The needs of the endoscopy unit, the staff, and the endoscopist should drive the selection process when choosing an EEMR. Extensive testing of the EEMR system capabilities, especially the ability to interface with existing software programs, is essential before purchasing an EEMR system.
