Reduction in the burden of hospital admissions due to cervical disease from 2003–2014 in Spain

Abstract

ABSTRACTBackground: Cervix uteri cancer is the 4th most common cancer among women worldwide and the second most frequent cancer in women under 45 years old in Spain. We aimed to describe the burden of hospital admissions by malignant neoplasia (MN) and in situ carcinoma (ISC) of the cervix in Spain from 2003 to 2014, a 12-year period that included the first years after introduction of an HPV vaccination program.Methods: This epidemiological study reviewed data from the Ministry of Health National Surveillance System, which includes more than 98% of Spanish hospitals. Hospitalization rate, mortality rate, and case fatality rates were calculated per year and age group.Results: We found 74,933 hospitalizations due to MN and ISC of the cervix. The average age at hospitalization increased significantly during the study period. The average length of hospital stay decreased significantly (p<0.001), while hospitalization costs increased. The mean hospitalization rate was 27.532 cases per 100,000 women (95% CI: 27.335-27.729). This rate decreased significantly during the study period. The mean mortality rate was 1.418 deaths per 100,000 women (95% CI: 1.373-1.463) and the mean case-fatality rate was 5.150% (95% CI: 4.992-5.308).Conclusion: Our study showed a substantial decrease in the hospitalization burden due to cervical disease. This decrease could be attributable to different causes including cervical cancer prevention measures, and changes in disease management. Further research is needed to confirm the cause. This information could contribute to further evaluations of the impact and cost effectiveness analysis of HPV vaccination in Spain.
