Implementation research to accelerate scale-up of national screen and treat strategies towards the elimination of cervical cancer.

BACKGROUND

Cervical cancer is a significant public health problem, with 570,000 new cases and 300,000 deaths of women per year globally, mostly in low- and middle-income countries. In 2018 the WHO Director General made a call to action for the elimination of cervical cancer as a public health problem.

MAIN BODY

New thinking on programmatic approaches to introduce emerging technologies and screening and treatment interventions of cervical precancer at scale is needed to achieve elimination goals. Implementation research (IR) is an important yet underused tool for facilitating scale-up of evidence-based screening and treatment interventions, as most research has focused on developing and evaluating new interventions. It is time for countries to define their specific IR needs to understand acceptability, feasibility, and cost-effectiveness of interventions as to design and ensure effective implementation, scale-up, and sustainability of evidence-based screening and treatment interventions. WHO convened an expert advisory group to identify priority IR questions for HPV-based screening and treatment interventions in population-based programmes. Several international organizations are supporting large scale introduction of screen-and-treat approaches in many countries, providing ideal platforms to evaluate different approaches and strategies in diverse national contexts.

CONCLUSION

For reducing cervical cancer incidence and mortality, the readiness of health systems, the reach and effectiveness of new technologies and algorithms for increasing screening and treatment coverage, and the factors that support sustainability of these programmes need to be better understood. Answering these key IR questions could provide actionable guidance for countries seeking to implement the WHO Global Strategy towards cervical cancer elimination.
