Protocol for the formative phase of a trial (SHE-CAN) to test co-designed implementation strategies for HPV-based cervical screening among vulnerable women in two diverse settings in India.

The quality and outcomes of existing screening services, readiness to transition to HPV-based screening, challenges in providing and participating in the cervical cancer care continuum, and acceptability of screening and treatment approaches will be examined. The knowledge gained about the current system, as well as recognition of actions to be taken, will inform a stakeholder workshop to co-design and evaluate implementation approaches for HPV-based screening through a cluster randomised implementation trial.
