- Annual patient admissions: The total number of patients admitted for overnight stays
- Staff size: The total number of employees, including physicians, nurses, and support staff
- Physical facility size: The total square footage of the hospital campus

These institutions often serve as referral centers for complex cases from smaller hospitals across their regions Nothing fancy..

Why Hospital Size Matters
The size of a hospital can significantly impact the care patients receive, though bigger doesn't always mean better for every situation.
Advantages of large hospital systems:
- Comprehensive services: Larger hospitals typically offer more specialized services and can handle complex cases that smaller facilities cannot
- Advanced technology: Major medical centers often have access to the latest medical equipment and technologies
- Research and clinical trials: Academic medical centers frequently offer access to latest treatments through clinical trials
- Specialist availability: Larger institutions typically have more specialists on staff, enabling multidisciplinary care
- 24/7 coverage: Major trauma centers and large hospitals usually maintain around-the-clock availability for emergencies
Considerations to keep in mind:
- Larger hospitals may have longer wait times for appointments and procedures
- The impersonal nature of very large institutions can sometimes impact patient experience
- Smaller community hospitals may provide more personalized care for routine needs
- Travel considerations can be significant for patients in rural areas

What is the difference between a hospital and a medical center?
The terms are often used interchangeably, but "medical center" sometimes implies a larger complex with multiple facilities, research capabilities, and educational programs. That said, there is no formal distinction, and usage varies across institutions.
