 This study aims to evaluate the effectiveness of continuous quality improvement, CQI, cohorts on access to primary healthcare, PHC. It will also assess the sustainability of the intervention for PHC processes, organizational changes and outcomes. The study will involve 48 multidisciplinary PHC clinics in two regions. In the intervention region, 24 clinics will receive the CQI intervention for 18 months, involving three activities, reflective sessions and problem prioritization, plan-do study act cycles, and group mentoring. In the control region, 24 clinics will receive an audit feedback report on access. Qualitative and quantitative data will be collected over a period of 36 months. This study will provide valuable insights into the effectiveness of CQI cohorts in improving access to PHC, as well as the sustainability of the intervention.
