Sepsis and Septic Shock in Low- and Middle-Income Countries.

ABSTRACT

Background: The greatest burden of sepsis- and septic shock-related morbidity and mortality is in low- and middle-income countries (LMICs). Accurate tracking of incidence and outcomes of patients in LMICs with sepsis has been limited by changing definitions, lack of diagnosis coding and health records, and deficits in personnel. Improving sepsis care in LMICs requires studying outcomes prospectively so that setting appropriate definitions, scoring systems, and treatment guidelines can be created. Our goal is to review the burden of sepsis and septic shock in LMICs, the evolution and applicability of definitions to LMICs, and management. Methods: The literature was searched through PubMed using a Boolean approach and the following terms sepsis, septic shock, low- and middle-income countries. Articles were read by the authors and relevant information was abstracted and included with citations to create a narrative review. Results: The estimated worldwide incidence of sepsis admissions is 31.5 million cases per year leading to 5.3 million deaths. The World Health Organization (WHO) has urged LMICs to establish sepsis prevalence and outcomes. Most authors and societies involved in creating sepsis and septic shock definitions have been from high-income countries (HICs). Applicability of sepsis definitions in LMICs is uncertain. Quick-Sequential Organ Failure Assessment (qSOFA) and universal vital assessment (UVA) are useful screening and triage tools in LMICs because they can be done at the bedside. The key tenets of management of sepsis and septic shock in LMICs include early fluid resuscitation and antibiotic therapy coupled with source control when there is a surgical process. Surgical causes of sepsis should be identified rapidly. Scaling up surgical capacity in LMICs is an important step to improve source control of sepsis. Conclusion: Management guidelines specific to LMICs for sepsis and septic shock need to be refined further and studied prospectively. Improving access to surgery will improve outcomes of surgical cases of sepsis.
