BACKGROUND: Few data are available on factors associated with the quality of Papanicolaou smears performed in primary care. OBJECTIVE: To identify the patterns and proficiency of cervical cancer screening among different primary care specialties. MATERIALS AND METHODS: Clinical and cytologic data from 21,833 Papanicolaou smears, submitted to a single large commercial laboratory by 176 clinicians during a 7-month period, were correlated with individual clinician and specialty characteristics according to indexes of specimen quality. RESULTS: Obstetrician-gynecologists, nurse practitioners, and physician assistants provided screening to a younger population of women compared with family physicians, internists, and general practitioners. Factors positively associated with a greater probability of a "satisfactory" smear or the presence of endocervical cells (as a marker of adequate sampling) were increasing patient age, use of the cytobrush, and the specialty of the obstetrician-gynecologist. Satisfactory smears were not associated with any increased identification of cytologic abnormalities compared with "limited" smears. In contrast, smears with endocervical cells showed a higher proportion of abnormalities compared with specimens without such cells. CONCLUSIONS: Differences in the performance of obtaining Papanicolaou smears exist between primary care specialties, but need further clarification. The use of the cytobrush and the presence of endocervical cells are criteria that reflect clinician proficiency more realistically than the laboratory criterion of satisfactory smear.
