Defined as “a broad set of supervisory interventions that improve provider performance through team-based learning approaches, including supportive supervision, the use of checklists, and in-person visits,” enhanced supervision is estimated to have the highest potential impact of all health systems interventions (USAID, 2017). But which strategies are most effective? Can strategies be adapted for different settings; monitored; improved? HRH2030’s landscape analysis report classifies and summarizes the most impactful enhancements for health workforce supervision and what direct effects enhanced supervision has been documented to have on maternal, newborn, and child health; HIV; family planning and reproductive health; and/or other service delivery outputs, or health outcomes.
