MRSA in the Field: Identification, Treatment, and Prevention

Methicillin-resistant Staphylococcus aureus (MRSA) remains one of the most significant multidrug-resistant organisms encountered in both healthcare and community settings. For EMS professionals, the risk of exposure is uniquely elevated due to frequent contact with diverse patient populations, unpredictable environments, and high-touch equipment. MRSA is no longer confined to hospitals—it is commonly encountered in homes, schools, athletic facilities, and long-term care settings, making it a routine concern in prehospital care. Understanding how MRSA spreads, presents, and persists in the environment is essential for protecting both providers and patients.

This course provides a comprehensive, evidence-based overview of MRSA tailored specifically to EMTs and paramedics. Learners will explore the pathophysiology of MRSA, current epidemiological trends, and the differences between community-acquired and healthcare-associated infections. Emphasis is placed on recognizing MRSA in the field, including common skin presentations often mistaken for minor conditions, as well as identifying signs of more severe or systemic infection. The course also highlights EMS-specific exposure risks, including contaminated equipment, ambulance environments, and patient transport between facilities.

In addition to clinical recognition, this course focuses heavily on practical application. EMS providers will review current CDC-recommended infection control practices, including proper use of personal protective equipment (PPE), hand hygiene, and effective cleaning and disinfection techniques. Guidance is also provided on patient management considerations, post-exposure procedures, and documentation requirements. By the end of this course, learners will be equipped with the knowledge and tools necessary to reduce transmission risk, enhance patient care, and maintain a safe working environment in the face of evolving antibiotic-resistant threats.
