Abstract
OBJECTIVE: To describe performance measures related to colposcopic examinations in Canadian cervical cancer screening programs; specifically, time to colposcopy, histological investigation rate, and agreement between cytology and histology. METHODS: As part of a national report on the performance of cervical cancer screening, aggregate provincial cervical cancer screening data provided by provinces to the Pan-Canadian Cervical Screening Network were used to evaluate colposcopy program performance measures for women 20 to 69 years of age who had a Pap test in 2009 and 2010. RESULTS: A total of 37 523 women had a high-grade or more severe Pap test result. The proportion of women who had a colposcopy ≤ 90 days after their Pap test ranged from 30.9% to 51.5%. Fewer women 60 to 69 years of age had a colposcopy than women in younger age groups. The proportion of women who had a high-grade or more severe Pap test result and colposcopy who had a biopsy within 12 months ranged from 82.1% to 96.5%. The proportion of biopsy results that agreed with the Pap test result ranged from 59.5% to 82.1%. CONCLUSION: The time from having a high-grade Pap test result to undergoing colposcopy must be reduced to lower the risk of adverse outcomes and the stress associated with delayed follow-up. The agreement between screening cytology and histology meets the national target of ≥ 65%. Although six of 13 provinces and territories provided data for colposcopy-related performance measures, more information is needed to assess colposcopy services accurately at the national level.
