Study looks at the pros and cons of voice recognition

05.05.2003


Voice recognition dramatically decreases the turnaround time for radiology reports – referring physicians are often getting results the same day their patients have the radiologic examinations – but technical problems with these systems are reducing some radiologists to typing rather than dictating those reports, a new study shows.



"There are many benefits of voice recognition, but unfortunately we have been facing some technical problems that are impacting our productivity, " says Joel Gross, MD, assistant professor of radiology at Harborview Medical Center in Seattle.

The biggest benefit of voice recognition is the reduction in report time turnaround, says Dr. Gross. "In 2001, when we used the traditional dictation system most of the time, it took an average 133 hours after the examination was completed before a report was finalized, says Dr. Gross. A preliminary report was available with 56 hours, notes Dr. Gross. (The traditional dictation method includes the radiologist dictating the report, a transcriptionist transcribing it, then the radiologist reading the transcribed report and making any necessary corrections before it is available to the referring physician as a finalized report.)


"With voice recognition as our main method (approximately 75%) of reporting in 2002, we have reduced that to 66 hours, with preliminary reports available within 14 hours," he says. "This number is slightly skewed because it includes cases in which the patients undergo the exam late in the evening, and the films aren’t read until the following day. With most exams, voice recognition is allowing us to offer same day reporting service," Dr. Gross says.

Another advantage of voice recognition is that a full report is available immediately to the radiologist. "At our teaching facility, the attending physician can more easily review cases with residents. There is not the delay caused by waiting for reports to be transcribed," he says. "This allows full evaluation of all the details in the report while reviewing the images or while the study is still fresh in the radiologist’s mind. Signing off on traditional dictated reports several days after reviewing images, one is often reduced to looking for obvious errors in the reports," he says.

However, "voice recognition is not a plug and play system," says Dr. Gross. Faster computers are needed so the system doesn’t freeze up. A good support team, available 24/7, that can fix problems or make necessary technical changes is essential, and must be budgeted for when making cost projections, he says. "We’ve had problems with poor voice recognition, difficulty stopping the transcription, spell-checking, filtering reports, losing macros and speech files, and other glitches that have slowed us down," says Dr. Gross.

"In addition we’ve also had problems with the system interfacing with our RIS system. We’ve had situations where our voice recognition system has overwritten changes we’ve made to our reports in our RIS system, which could potentially lead to medico-legal problems," he says. These technical problems have led some radiologists to simply type in the report themselves instead of dictating into the voice recognition system, says Dr. Gross. "These problems lead to a decrease in radiologists productivity and satisfaction," he adds.

"I’m optimistic that voice recognition will become a viable part of the radiology practice," says Dr. Gross. "However, not only must there be improvements in the voice recognition technology itself, but other technical problems that impede efficiency must be addressed," he says.

Dr. Gross will present his study May 5 during the American Roentgen Ray Society Annual Meeting in San Diego.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
