Appendix 1. Recommendations of the Ontario Cervica

Target Population This practice guideline applies to all women who are, or have ever been, sexually active.

Recommendations Please note that evidence ratings are in brackets. Please see the scale in Appendix 2.

Optimal Cervical Screening Tool

Liquid-based cytology (LBC) is the preferred tool for cervical cytology screening. (B-II) Conventional smear cytology remains an acceptable alternative. (C-III)

Optimal Screening Circumstances

Given the lower incidence and mortality associated with organized screening programs (with recall systems) elsewhere, a province-wide cervical screening program with an adequate recall mechanism is recommended. (A-II)

Screening Initiation

Cervical cytology screening should be initiated within three years of first vaginal sexual activity (i.e., vaginal intercourse, vaginal/oral and (or) vaginal/digital sexual activity). (C-III)

Screening Interval These recommendations do not apply to women who have had previous abnormal Pap tests. Please see the Management of Women with Abnormal Cytology section for further information.

l Screening Guidelines Development Committee

Screening should be done annually until there are three consecutive negative Pap tests. (C-III)

Screening should continue every two to three years after three annual negative Pap tests. (B-II)

Screening at a three-year interval is recommended, supported by an adequate recall mechanism. (B-II)

Women who have not been screened in more than five years should be screened annually until there are three consecutive negative Pap tests. (C-III)

Screening Cessation

Screening may be discontinued after the age of 70 if there is an adequate negative screening history in the previous 10 years (i.e., 3–4 negative tests). (B-II)

Screening Women with Special Circumstances

Immunocompromised or HIV-positive women should receive annual screening. (C-III)

Examples of situations where women may be immunocompromised include women who have received transplants and women who have undergone chemotherapy.

Screening can be discontinued in women who have undergone total hysterectomy for benign causes with no history of cervical dysplasia or human papillomavirus. (C-III)

Women who have undergone subtotal hysterectomy (with an intact cervix) should continue screening according to the guidelines.
