Global disease burden of cervical cancer and the association of screening coverage with quality of disease management.

Objectives: To analyze the global disease burden of cervical cancer and the association between screening coverage and the quality of disease management.

Methods: The data of global burden of cervical cancer 2021 and the data of cervical cancer screening 2019 were obtained from IHME Global Burden of Disease (GBD) and the WHO Global Health Observatory (GHO), respectively. The age-standardized disease burden index was calculated, the Quality of Disease Management Index (QCI) was determined with principal component analysis, the correlation between QCI and cervical cancer screening coverage was examined with linear regression analysis by regions and populations.

Results: The burden of cervical cancer and the quality of its management exhibited significant variability across countries with differing levels of social development. The indicators of cervical cancer burden in China were close to the average level of countries with higher socia-demographic index (SDI). The global QCI was 22.22 (10.50, 35.43), and that of China was 26.30. The global screening coverage rate for cervical cancer was 42% (12%, 86%) and that in China was 31%. After adjusting for the social development level of countries, the coverage level of cervical cancer screening was associated with QCI (=0.27, <0.01), no matter in countries with low or high SDI (>0.05). The association was significantly stronger among younger women (=1.48, <0.05).

Conclusions: There are discrepancies in both the disease burden of cervical cancer and the quality of disease management among countries with different socioeconomic levels, and there is still considerable room for improvement in China. Expanding coverage of cervical cancer screening may be an effective strategy to enhance the management quality of cervical cancer, particularly among younger women where the screening benefits are most pronounced.
