<p>From April 2022 to July 2023, we implemented a longitudinal mentorship model as part of an IPC multimodal intervention programme in 225 PHCs across three states. The programme involved IPC experts (mentors) providing training, monthly monitoring, onsite mentorship with task shifting from external mentors to facility staff, supportive supervision, and data utilisation for performance improvement. We conducted baseline and end-line assessments using a standardised IPC checklist to evaluate performance in IPC standards. We also conducted a qualitative survey to assess mentor and mentee perceptions on IPC knowledge and skills, attitude and compliance to IPC standards, mentorship experience, and the effectiveness of task-shifting. Respondents rated their experiences on a 4-point Likert scale ranging from "Strongly Disagree" to "Strongly Agree" and provided detailed feedback through open-ended questions.</p>
