Area of Science:

  • Toxicology
  • Health Informatics
  • Information Management

Background:

  • Poison control centers rely on rapid access to critical information.
  • Traditional microfiche systems for Poisindex may present access time challenges.
  • Advancements in technology offer potential improvements in information retrieval.

Purpose of the Study:

  • To quantitatively compare information access times between microfiche and computerized Poisindex.
  • To evaluate the efficiency gains offered by a computerized drug information database.
  • To assess the impact of improved access times on poison center operations.

Main Methods:

  • A prospective time study was conducted at the Pittsburgh Poison Center.
  • Professional time management engineers observed certified poison information specialists.

  • Access time was measured from request to initial information display on microfiche and computer.

    • Main Results:

    • Average access time for microfiche was 37.2 seconds; for the computerized version, it was 18.0 seconds.
    • The computerized system demonstrated a 106% improvement in access time.
    • Annual time savings were estimated at 213 hours based on 40,000 cases.

    Conclusions:

    • Computerized Poisindex significantly enhances information retrieval efficiency.
    • Time savings can potentially improve patient care through more extensive information access and better documentation.
    • The transition to computerized systems is crucial for modern poison control center operations.
