2025-08-26 00:00:00 To improve the management of severely ill hospitalized patients in low-income settings, the World Health Organization (WHO) established a triage tool called “Quick Check” to provide clinicians with a rapid, standardized approach to identify patients with severe illness based on recognition of abnormal vital signs. Despite the availability of these guidelines, recognition of severe illness remains challenged in low-income settings, largely as a result of infrequent vital sign monitoring. E-SIMS is a mobile application for Electronic Severe Illness Management Support that enables emergency health caregivers to triage and prioritize patients. E-SIMS prompts health care works to ensure that appropriate interventions are provided in their specified time.
