A new computer program, Urinalysis-Review™, effectively assesses medical technologists' competency in microscopic urinalysis. This tool establishes baseline performance metrics for this common laboratory test, aiding future educational improvements.

Area of Science:

  • Clinical laboratory science
  • Medical technology assessment
  • Diagnostic urinalysis

Background:

  • Microscopic urine sediment examination is a frequent laboratory test.
  • No prior studies detailed medical technologist competency in this area.
  • Lack of standardized competency assessment tools hinders evaluation.

Purpose of the Study:

  • Develop and implement a computer-based tool for assessing microscopic urinalysis competency.
  • Establish baseline competency measurements for medical technologists.
  • Provide a uniform assessment method across institutions.

Main Methods:

  • Developed and utilized Urinalysis-Review™ software for competency testing.
  • Administered eight exams over two years to an average of 58 medical technologists per exam.

  • Exams included structure identification (cells, casts, crystals, organisms/artifacts) and quantification questions.

    • Main Results:

    • Medical technologists achieved high accuracy rates: 84% for cells, 72% for casts, 79% for normal crystals, 65% for abnormal crystals, 81% for organisms/artifacts, and 89% for quantification.
    • These results may slightly underestimate actual competency due to image analysis without chemistry data.

    Conclusions:

    • Computer programs are feasible for clinical laboratory competency assessment.
    • The study provides baseline competency data for microscopic urinalysis.
    • This data will inform future studies on continuing education effectiveness.
