Who Are Emergency Medicine Physicians?
Emergency medicine physicians (EM physicians) are highly trained medical professionals who specialize in diagnosing and treating unforeseen illnesses and injuries. They work primarily in emergency departments (EDs), urgent care centers, and trauma units and are skilled at managing patients of all ages, often with minimal patient history.
Their responsibilities include:
- Rapid assessment and stabilization
- Trauma and resuscitation procedures
- Coordination with specialists
- Managing medical crises such as strokes, heart attacks, and drug overdoses
- Public health and disaster preparedness
With rising demand for emergency care and an increasing number of patients accessing emergency departments, EM physicians are central to the American healthcare system.

According to Ampliz and other healthcare data sources, there are over 4,000 emergency medicine physician group practices across the US. These range from small local practices to large multi-state physician groups serving hundreds of hospitals and millions of patients annually.

Challenges in Finding Emergency Medicine Physician Group Decision-Makers
Marketing to emergency medicine physician groups can be highly rewarding—but it’s not without challenges. Identifying the right contacts and decision-makers in these large, often multi-location groups requires precision and insight.
1. Decentralized Decision-Making
Many large EM groups operate in multiple hospitals and states. Purchasing decisions for medical devices, software, or services may be decentralized, varying by region or hospital system.
2. High Turnover & Rotational Schedules
Emergency departments often have rotating staff, making it difficult to find consistent contacts or stable leadership.
3. Limited Public Profiles
Unlike private practice specialists, many EM group leaders don’t maintain robust online profiles, making LinkedIn or general searches unreliable.
4. Time-Sensitive Workflows
Emergency medicine is fast-paced. Gaining the attention of key stakeholders who are constantly dealing with urgent cases can be particularly tough.
Why It’s Important to Market to Emergency Medicine Groups
Emergency medicine groups are crucial stakeholders for healthcare brands that offer:
- Emergency medical equipment (ventilators, monitors, stretchers)
- Diagnostic tools (portable ultrasound, lab devices)
- Health IT solutions (EHRs, telehealth platforms)
- Staffing, revenue cycle, or credentialing services
Engaging EM physician groups ensures your products are used where they’re needed most—at the point of first contact and critical care.
Benefits of marketing to EM groups:
- High patient volume = High product utilization
- Rapid adoption of life-saving technology
- Opportunity to expand into broader hospital systems
- Strong influence on hospital purchasing committees
