Infection and sepsis are among the leading causes of death worldwide, particularly in middle- and low-income countries.The Surviving Sepsis Campaign has launched an initiative to improve sepsis care in resource-limited settings by employing the 'Scan-Teach-Treat' Approach. In this prospective before-after study, three interventions will be performed: First four months period: collection of baseline data on the clinical management of patients with acute infection. Second four months period: During the first days, a 1.5-day focused training program will be performed (participants: health care workers of primary care facilities within the catchment area of the Gitwe hospital and health care workers of the Gitwe hospital). Then, a simple management protocol to care for patients with an acute infection will be implemented into clinical practice. During the third four months period, a 'Sepsis First Aid' kit containing essential resources to treat patients with an acute infection (antimicrobials, fluids, data documentation sheet) will be distributed to primary care facilities and the emergency department of the Gitwe hospital. During the 8 months following the focused training program (periods 2 and 3), data collection will continue. It is hypothesized that implementation of a simple clinical management protocol and exposure of health care workers in the Gitwe Hospital area to a focused training program on the management of acute infections will increase the rate of evidence-based interventions performed in patients with an acute infection during the first six hours after hospital admission (administration of oxygen and fluids whenever indicated, timely administration of antimicrobial drugs, source control measures).
