Area of Science:

  • Medical Laboratory Science
  • Health Informatics

Background:

  • Traditional data entry for laboratory results is time-consuming and prone to errors.
  • Existing methods often involve manual coding and keyboard input, delaying report turnaround times.

Purpose of the Study:

  • To design and evaluate a speech-based system (Vigilante) for direct data entry of urine microscopy, culture, and sensitivity test results at the bench level.
  • To reduce data entry time, improve accuracy, and expedite report issuance.

Main Methods:

  • The Vigilante system was developed for natural continuous speech input, incorporating graphical and audio feedback for error correction.
  • A three-month comparative study involving 2360 urine specimens evaluated Vigilante against traditional data entry methods with multiple operators.

Main Results:

  • Vigilante significantly reduced data entry time compared to traditional methods.
  • The system demonstrated improved accuracy in reporting and decreased overall report issuance time.
  • Graphical and audio feedback features facilitated efficient error recognition and correction.

Conclusions:

  • Direct data entry using speech technology, as exemplified by the Vigilante system, provides a practical, reliable, and innovative solution for laboratory reporting.
  • The Vigilante system is now routinely used for urine test results and is adaptable to other laboratory methodologies and data entry tasks.
