Abstract
This study examined the impact of applying the Bethesda System guidelines for specimen adequacy on cytopathologic diagnosis at the Johns Hopkins Hospital laboratory of cytopathology during a one-year period. Application of the Bethesda guidelines resulted in a 1.3% unsatisfactory rate. In addition, 3.8% of specimens were satisfactory but contained an inadequate endocervical component (IEC). Smears obtained after a cone biopsy or an initial IEC smear were IEC in 16.5% and 18.7% of cases, respectively. The IEC rate following an initial smear lacking an endocervical component was 11.8% in repeat specimens obtained with an endocervical brush as compared to 29.4% in those obtained with a spatula alone. The reproducibility of the Bethesda criteria for assessing endocervical sampling was evaluated by comparing the level of agreement between three independent reviewers examining 40 test cases. Three- way agreement was achieved in 75% of cases. Two-way agreement ranged from 80.0% to 87.5%. We conclude that implementation of the Bethesda System guidelines for assessing specimen adequacy should produce a minimal impact on cytopathologic reporting and gynecologic practice. Repeat specimens lacking an endocervical component may be encountered relatively frequently in certain subsets of patients.
