What is considered a Small hospital? Defining size, scope, and community role

September 22, 2025 •

4 min read

According to widely accepted healthcare classifications, a hospital with fewer than 100 beds is typically defined as a small hospital. This designation is crucial for understanding the scope of services, operational challenges, and vital role a small hospital plays within its community.

Quick Summary

The bed count is the primary metric for defining a small hospital, with the standard benchmark being a facility that contains fewer than 100 beds. This classification often overlaps with rural hospitals and includes specialized subsets like Critical Access and micro-hospitals.

Key Points

Bed Count: A hospital is generally classified as small if it has fewer than 100 beds.
Rural Importance: Many small hospitals are found in rural areas, often serving as the primary source of local care.
Critical Access Designation: Critical Access Hospitals are a special type of small, rural hospital with 25 or fewer beds, vital for underserved communities.
Micro-Hospitals: A modern development, these are very small facilities—sometimes with fewer than a dozen beds—focusing on accessibility and cost-effectiveness.
Essential Role: Despite facing operational challenges, small hospitals provide essential services and are critical for stabilizing patients before potential transfer to larger facilities.
Diverse Landscape: Small hospitals can be found in both rural and urban settings, with urban versions often specializing in niche care.
Unique Challenges: Small hospitals face issues related to financial stability, staffing shortages, and access to advanced technology.

Defining a Small Hospital by Bed Count

In the healthcare industry, the most common criterion for classifying a hospital's size is its total bed capacity. A facility is generally labeled a small hospital if it has fewer than 100 inpatient beds. This metric serves as a foundational benchmark for researchers, policymakers, and industry analysts when discussing hospital demographics and service models.

While this bed-count rule is a useful starting point, it's important to remember that it is a general guideline. Some classification systems may have slightly different thresholds, and the definition can be further refined by factors such as location, revenue, and service specialization.

The Relationship Between Size and Location

Historically, many small hospitals are located in rural communities, where they serve as the primary source of medical care. This geographic reality has led to specific policy and funding considerations, such as the Critical Access Hospital (CAH) designation. Conversely, small hospitals can also exist in densely populated urban areas, where they often focus on a specific, niche specialization.

Special Classifications for Small Hospitals

Not all small hospitals are the same. A few specific designations are used to further categorize and define their functions, especially concerning their vital role in underserved communities.

Critical Access Hospitals (CAHs)

This designation was created by the Centers for Medicare and Medicaid Services (CMS) to help support small, rural hospitals financially. To qualify as a CAH, a facility must meet specific criteria:

Have 25 or fewer inpatient beds.
Maintain an average length of stay of 96 hours or less for acute care patients.
Be located in a rural area and be at least 35 miles from another hospital (with some exceptions).
Provide 24/7 emergency care services.

CAHs are a crucial part of the rural healthcare system, stabilizing patients and providing essential services, but they face significant financial challenges due to their limited scale and reliance on government funding.

Micro-Hospitals

Representing an emerging trend in healthcare, micro-hospitals are small-scale, licensed inpatient facilities with very few beds—often less than a dozen. These facilities are designed for accessibility and cost-effectiveness, offering 24/7 emergency services, basic lab work, and imaging. They are essentially smaller versions of a traditional hospital and can be a strategic option for healthcare systems looking to expand their footprint into new or underserved areas without the massive investment required for a large hospital.

Services and Scope of Care

The range of services offered by a small hospital can vary greatly depending on its location and resources. Here are some common services provided:

24/7 Emergency Services
Inpatient care and observation
General surgery
Basic laboratory testing
Radiology and imaging (X-rays, ultrasounds)
Outpatient services
Rehabilitation services (physical, occupational, and speech therapy)
Primary care clinics
Specialty consultations (often via telehealth)

A Comparison of Small vs. Large Hospitals


Feature	Small Hospital	Large Hospital
Bed Capacity	Fewer than 100 beds	Typically 500 or more beds
Location	Often rural; can be specialized in urban areas	Predominantly urban and suburban areas
Services	Broad but limited scope; focus on essential care	Comprehensive and specialized services, including advanced surgery and technology
Staffing	Smaller, more generalized staff; high staff-to-patient ratio	Large, specialized staff; more departmental specialization
Technology	Basic and essential medical equipment	Advanced medical technologies and specialized equipment
Patient Flow	Often stabilizes and transfers critical patients	Manages all levels of patient acuity, from basic to highly critical
Financial Stability	More vulnerable; often reliant on government funding	Greater financial resources and economies of scale

Operational Challenges for Small Hospitals

Small hospitals face a unique set of obstacles that can impact their sustainability and ability to provide care. These include:

Financial Instability: With smaller budgets and lower patient volumes, small hospitals are often more sensitive to changes in reimbursement models and economic downturns. This is particularly true for rural hospitals, which face greater challenges in delivering essential services.
Staffing Shortages: It can be difficult for small hospitals to recruit and retain staff, particularly specialized physicians and nurses. This can lead to reliance on locum tenens staff and a heavier workload for existing employees.
Access to Advanced Technology: The high cost of advanced medical equipment can make it prohibitive for small hospitals to invest in state-of-the-art technology, potentially limiting their diagnostic and treatment capabilities.
Maintaining Community Connection: While a close community connection is a strength, it also means these hospitals must be agile and responsive to the specific, and sometimes limited, needs of their local population.

The Role of Small Hospitals in the Healthcare Ecosystem

Despite their challenges, small hospitals are an indispensable part of the healthcare system. They provide critical access to care in underserved areas, serving as a lifeline for communities that would otherwise have no local hospital. Their community-centric approach can also lead to more personalized patient care and closer relationships between providers and patients. The evolution of models like micro-hospitals demonstrates an ongoing effort to innovate and adapt the small hospital concept to meet modern healthcare demands for accessibility and efficiency.

Conclusion

While the definition of what is considered a small hospital is most commonly based on a bed count of fewer than 100, the reality is far more nuanced. This category includes everything from rural Critical Access Hospitals, which provide a local lifeline, to specialized micro-hospitals that focus on convenience and efficiency. Understanding the different types of small hospitals, their unique challenges, and the essential role they play is key to appreciating their significant contribution to the broader healthcare landscape.
