This study created a tool to assess technologists' ability to detect critical findings on blood smears. Education via video presentation improved their proficiency in identifying red blood cell morphology.

Area of Science:

  • Hematology
  • Medical Laboratory Science
  • Clinical Diagnostics

Background:

  • Accurate detection and reporting of clinically significant findings on blood smears are crucial for patient diagnosis and management.
  • Assessing the competency of laboratory technologists in peripheral blood smear analysis is essential for maintaining high-quality diagnostic services.
  • Standardization of red blood cell (RBC) morphology interpretation is vital for consistent and reliable results.

Purpose of the Study:

  • To develop and validate a competency assessment tool for evaluating technologists' skills in identifying and reporting critical findings on peripheral blood smears.
  • To determine the impact of a standardized video-based educational intervention on improving technologists' proficiency in RBC morphology assessment.
  • To enhance the accuracy of automated white blood cell differential processes through improved manual smear review skills.

Main Methods:

  • A nonequivalent pretest-posttest control group design combined with a modified time-series analysis was employed.
  • The study was conducted in the Core Hematology and Special Hematology Laboratories of a large medical center.
  • Participants included technologists from all shifts, utilizing a convenience sampling method.

Main Results:

  • A competency assessment method was successfully developed to measure technologists' performance in scanning peripheral blood smears.
  • The study identified specific areas of competency related to the detection and reporting of significant findings.
  • Preliminary data suggests that the video presentation intervention may lead to improved proficiency in RBC morphology interpretation.

Conclusions:

  • The developed competency assessment tool provides a reliable method for evaluating technologists' skills in peripheral blood smear analysis.
  • Video-based education focused on RBC morphology standardization shows promise in enhancing technologist proficiency.
  • Continuous assessment and targeted education are important for maintaining and improving diagnostic accuracy in hematology laboratories.
