Sophisticated indexing systems for electronic health records improve coding efficiency but require human verification. Expert Network software shows promise for automated data review, reducing the need for manual checks in clinical text classification.

Area of Science:

  • Medical Informatics
  • Health Information Management

Background:

  • Mayo Clinic utilizes high-volume, high-resolution patient record indexing.
  • Automated algorithms are being developed to assist human coders in classification.
  • Evaluating the efficiency and accuracy of these systems is crucial for production environments.

Purpose of the Study:

  • To evaluate the speed and error rates of different indexing systems in a production setting.
  • To compare the performance of code browsers and free text indexing systems.
  • To identify the most effective system for automating clinical text classification.

Main Methods:

  • Evaluation of code browsers and free text indexing systems.
  • Assessment of speed and error rates in a live production environment.

  • Comparison of system performance, including Expert Network software.

    • Main Results:

    • More advanced indexing systems offer measurable time savings in the coding process.
    • These systems exhibit incompleteness, necessitating backup or human verification.
    • Expert Network demonstrated superior rank ordering of clinical text.

    Conclusions:

    • Sophisticated indexing systems enhance coding efficiency but require human oversight.
    • Expert Network shows potential for establishing automated review thresholds for clinical data.
    • Further development may lead to reduced human review in medical record coding.
