Cost-effectiveness of public health programs to reduce inequalities in organized cancer screening ; Efficience de programmes de santé publique visant à réduire les inégalités de participation au dépistage organisé des cancers

Background. Increasing participation in organized cancers screening and reducing social and geographical inequalities in participation represent a major public health issue. Objectives. To determine the costeffectiveness of 2 interventions aiming at increasing participation and reducing inequalities in organized cancer screening in France Methods. We conducted a cost-effectiveness analysis from the payer's perspective: 1) of an invitation to a mobile mammography unit (MM) unit for breast cancer screening from retrospective data (n = 37461), 2) of a patient navigation program (PN) for colorectal cancer screening from a randomized controlled trial (n = 16250). Results. The incremental cost per additional screen compared with usual screening was: 1) € 611 [492-821] for the invitation to the MM (+ 3.8% [2.8-4.8], + € 23.21 [22.64-23.78] ), and 2) of € 1 212 [872-1 978] for PN (+ 3.3% [1.5-5.0], + 39.70 €). Effectiveness and cost-effectiveness were greater in deprived areas and in remote areas for MM, whereas they were less favorable in deprived areas for PN. Conclusion. MM and PN can reduce inequalities while being more efficient in remote areas and in deprived areas for MM, while, to achieve this, PN should target deprived people, even if being not the most efficient strategy. Research needs to be pursued to determine the optimal conditions for MM integration in organized breast cancer screening, and to improve the effectiveness and cost-effectiveness of PN, which can not be recommended as experimented for now. ; Contexte.
