HSD58 Impact of the COVID-19 Pandemic on Cervical Cancer Screening Rates in Colombia: An Interrupted Time Series Analysis, Stratified By Region

Abstract

The objective of this study is to measure the national impact of COVID-19 on cervical cancer screening rates in Colombia in five of its geographic regions to inform future health policy decision making. This study utilized a quasi-experimental interrupted time-series design to examine changes in trends for the number of cervical cancer screenings performed in five geographic regions of Colombia. In the rural region of Vichada, we found the lowest incidence of cervical cancer screenings, totaling at 3,771 screenings. In Cundinamarca, the region which hosts the capital city, a total of 1,213,048 cervical cancer screenings were performed. The researcher measured the impact on cervical cancer screenings in December 2021 against the counterfactual. This impact was ∼269 cases that were not performed in December 2021 as a result of the COVID-19 pandemic compared to the counterfactual. In Cundinamarca, unlike other regions, we observed a stagnant pre-pandemic trend, a sharp drop in screenings in March 2020, and an immediate upward trend starting in April 2020. In the month of April 2020, compared to the counterfactual, there were 27,359 screenings missed, and by the month of December 2021, there were only 5,633 cervical cancer screenings missed. The region of Cundinamarca’s sharp climb back to pre-pandemic screening levels could signal the relatively stronger communication system in the region, and especially in the capital district of Bogota, in re-activating the economy. This can serve as an example of what should be implemented in other regions to improve cervical cancer screening rates. Areas for further research include the examination of social determinants of health, such as the breakdown of the type of insurance screened patients hold (public versus private), zone (urban versus rural), insurance providers of those screened, ethnicities of the patients screened, and percentage of screenings that resulted in early detection of cervical cancer.
