Background Cervical cancer screening (CCS) by means of Pap smears has led to a decrease in cervical cancer incidence and mortality. In the absence of organized programmes, CCS is opportunistic in Belgium and Switzerland. This might result in a high level of CCS overuse, as screening practices do not conform to the recommended 3-yearly screening interval and the target age-ranges (Belgium: 25–64, Switzerland: 20–70). This study aimed to assess trends in CCS uptake and overuse in Belgium and Switzerland and their social determinants, in the light of reimbursement initiatives, which were implemented in both countries. Methods Data from five waves of the Belgian Health Interview Survey (1997–2013) (N=11 141) and Swiss Health Interview Survey (1992–2012) (N=32 696) were used. We performed Poisson regressions to estimate adjusted prevalence ratios (APR), controlled for socio-economic and socio-demographic characteristics and health status. CCS overuse was operationalized as screening more than once every 3 years and screening above recommended age-range. Results CCS uptake remained relatively stable over time, with a mean coverage of 70.9% in Belgium and 73.1% in Switzerland. Educational and income gradients were found in both countries. Concerning CCS overuse, women above screening-eligible age showed consistently high screening rates, but screening within the past year declined significantly in both countries, matching the temporal implementation of the reimbursement initiatives. Conclusions Although no increase in CCS coverage could be established, CCS has become more efficient in both countries as Pap smear overuse at the population level has declined after the implementation of reimbursement measures tackling CCS overuse.

Cervical cancer is the cancer that can be the most effectively prevented by screening. Western countries have implemented Pap smear screening and there is highly effective treatment for women with high-grade lesions or early stage invasive cancer, such as laser vaporisation or excision, cryotherapy or hysterectomy. This strategy has led to a decrease of incidence, morbidity and mortality from this disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
