Introduction: Cervical cancer has high rates of incidence and mortality in women in Brazil. Monitoring of control actions has been limited to the number of tests performed and not to the women examined due to the lack of a unique identifier in the information system. Objective: To analyze indicators of cervical cancer screening actions among women aged 25-64 years with a record of the first cytopathological examination reported at Siscolo from 2007 to 2013. Method: Study of time series of indicators of cervical cancer screening actions were calculated for women aged 25-64 years who had their first cytopathological exam identified at Siscolo between 2007 and 2013. Trend analysis was performed using Prais-Winsten regression. Result: The uptake indicator showed an increasing trend only in the South (p=0.038) while overall positivity (any cytopathological alteration) remained stationary in the country (p≥0.108). Transformation zone sampling rate showed a decreasing trend in all regions (p<0.05), while the ratio between high-grade intraepithelial lesion and squamous cell carcinoma showed an increasing trend in the Northeast (10.3 in 2007 to 13.3 in 2013), Southeast (17.5 to 20.2) and South (20.2 to 30.4) regions. Conclusion: The increasing ratio between high-grade lesion and cancer in three regions of the country indicates a good screening performance in these locations. Indicators with a stationary trend and a decreasing trend in the transformation zone sampling rate need monitoring.
