Through the USAID-funded Organized Network of Services for Everyone’s Health (ONSE) Activity, MSH is assisting Malawi’s National Malaria Control Program to provide high-quality malaria services at the facility and community levels in 10 districts, covering nearly a third of the country. Our team in Malawi share recent results on strengthening malaria services through Outreach Training and Supportive Supervision (OTSS). Designed to provide ongoing support to clinicians, data, and laboratory staff, OTSS combines a standardized checklist with targeted mentorship and supportive supervision to identify areas for improvement and strengthen clinical and diagnostic services in health facilities. This webinar shares lessons learned on how the application of OTSS, as part of broader quality assurance systems, impacts staff performance and improves the provision and quality of malaria services.
