Objective:
To assess the status of emergency medical services (EMS) in low- and middle-income countries (LMICs) and identify key barriers to effective service delivery.
Methods:
A systematic review was conducted following PRISMA guidelines. PubMed, Scopus, Embase, and Cochrane Library were searched in March 2025 for studies on emergency medical service systems in low- and middle-income countries published between 2009 and 2023. Seventeen peer-reviewed studies were included. Thematic analysis was applied to synthesize findings and identify recurring challenges across EMS systems.
Results:
EMS systems in LMICs ranged from fragmented and informal arrangements to partially integrated national systems. Key barriers included weak governance, inadequate financing, workforce shortages, poor communication and coordination, and limited infrastructure. Findings suggest that EMS underperformance is driven not only by resource constraints but also by fragmentation and limited integration of community-based emergency networks. Informal responders, such as community volunteers, frequently fill gaps in formal EMS but remain largely absent from policy frameworks.
Conclusions:
Strengthening EMS in LMICs requires integrated approaches that bridge formal and informal systems, alongside improved workforce capacity and coordination, to enhance emergency care outcomes.

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...

Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
