ARCS is a multi-country collaboration sponsored by the Liverpool School of Tropical Medicine aimed to improve the survival and quality of life of patients hospitalized with sepsis through multidisciplinary applied health research at the health facility and health system levels. In its role as implementing partner in Uganda, Walimu conducted multiple studies to help address knowledge gaps in key areas of sepsis understanding in Uganda, including epidemiology, host response, use of point-of-care ultrasound, quality improvement, patient perspectives and policy.
