title: Using a CompuCyte Pathfinder to evaluate cytotechnology student diagnostic performance.
abstract: OBJECTIVE
  To determine whether the Pathfinder Cytology System facilitates comparison of initial student diagnoses to rescreener diagnoses; provides a platform for collection, storage and retrieval of data on student screening performance; and generates a student screening "score."
  
  
  METHODS
  Using two CompuCyte Pathfinder units networked to a PC server and printer, eight cytotechnology students prescreened 1,224 gynecologic cases and entered their results into the Pathfinder database. Five staff cytotechnologists rescreened the cases and entered their diagnoses. The database containing the initial and rescreen diagnoses were transferred to a modified scoring grid that computed a screening "score" for each of the students.
  
  
  RESULTS
  Student diagnoses matched cytotechnologist target diagnoses in 1,107 to 1,224 total cases (90.4%). Of these 1,107 cases, 996 (81.3%) were reported as "within normal limits" (negative) by both student and cytotechnologist, and 111 (9.1%) were target diagnosed as abnormal (atypical squamous cells of undetermined significance [ASCUS] or above) by both student and cytotechnologist. Of 117 remaining cases, 112 (9.2%) were considered minor discrepancies (one-step discrepancy--e.g., benign cell change-reactive vs. ASCUS--favor reactive), and 5 (0.4%) were considered significant discrepancies (two or more diagnostic categories of difference between student and cytotechnologist-within normal limits vs. low grade squamous intraepithelial lesion). The modified scoring grid developed by CompuCyte for this study was able to compute a numerical score for each student.
  
  
  CONCLUSIONS
  Our preliminary assessment indicated that Pathfinder will facilitate evaluation of student performance. The system shows potential for eliminating the "paper trail" and manual dotting required for traditional student evaluation and, with the addition of a scoring program, may be standardized for use in both educational and clinical settings.
