Probability of early repeat Pap smear in an integrated cervical screening programme.

The integration of routine Pap smear practice based on self-referral into an organized programme based on personal invitation is the recommended approach to cervical cancer screening. In this study, the cytology archive of the integrated cervical screening programme implemented in the Faenza district (northern Italy) was used to compare the population of women responding to invitation with that of self-referred women for the cumulative probability of early (< 36 months) repeat Pap smear after a negative result. Between 1995 and 1998, women aged 25-64 living in five municipalities of the district were targeted by the first round of the programme.
