What You'll Learn

There are 6,090 hospitals in the US
Out of the 6,090 hospitals, 5,141 are community hospitals, accounting for 84% of all hospitals in the US. The remaining hospitals are categorized as non-profit or for-profit organizations. The American Hospital Association defines a health system as a group of hospitals and healthcare providers that are linked through common ownership or management. This definition can include multi-hospital systems, single hospital systems, and other forms of integration between providers.
The history of hospital systems in the US can be traced back to the 1940s, when around 50 hospital systems were recognized, mostly affiliated with religious organizations or operating as non-profit entities. The first investor-owned system was established in 1960, marking a shift towards more diverse ownership structures. By 1980, a significant increase was observed, with a survey by the American Hospital Association identifying 267 systems, reflecting the growth and evolution of the healthcare landscape in the country.
Today, the American Hospital Association continues to play a pivotal role in advocating for hospitals and health systems nationwide. It conducts comprehensive surveys, such as the AHA Annual Survey, to gather data on various aspects of hospitals, including the number of government hospitals, hospitals in each state, and the availability of hospital beds. This information is invaluable for understanding the current state of healthcare infrastructure and identifying areas for improvement.
In summary, the United States boasts an extensive network of 6,090 hospitals, supported by a range of health systems and community-based initiatives. While the number of hospital beds has decreased, the evolution of health systems and the integration of diverse providers reflect ongoing efforts to enhance the accessibility and quality of healthcare services for Americans nationwide.

417 health systems, 4,063 hospitals are affiliated
The US healthcare system is a complex network of hospitals, health systems, and other healthcare providers. As of 2022, there are 417 health systems and a total of 6,090 hospitals in the United States. Out of these, 4,063 hospitals, or 67%, are affiliated with a health system, accounting for 75% of all hospital beds. Health systems can vary significantly in size, ranging from 1 to 161 hospitals and 25 to 39,825 beds, with 58% of systems having 1,000 or fewer hospital beds.
The American Hospital Association (AHA) defines a health system as either a multihospital system or a diversified single hospital system. A diversified single hospital system can be categorized as a system by bringing into membership three or more non-hospital pre-acute or post-acute healthcare organizations, with at least 25% ownership or lease of these organizations. The AHA's definition does not include other provider types, such as post-acute care providers and non-ownership contractual relationships.
The Agency for Healthcare Research and Quality (AHRQ) offers a different perspective on defining health systems. According to the CHSP Initiative, a health system is an organization that includes at least one hospital and a group of physicians providing comprehensive care, connected through common ownership or joint management. This definition focuses on the integration of care services rather than the mere ownership of multiple hospitals.
The variation in definitions of health systems leads to differences in the identification of total systems. The AHRQ's Compendium of U.S. Health Systems utilizes proprietary matching algorithms and a comprehensive construction process to identify health systems. This process involves name and address matching, aggregating regional subsystems, applying exclusion criteria, and removing hospital management companies. The result is a list of 1,275 unique health systems, which highlights the impact of definition and methodology on the understanding of the US healthcare landscape.

Health systems range from 1 to 161 hospitals
The number of hospitals in the US stands at 6,090 total hospitals and 417 health systems. Health systems range from 1 to 161 hospitals, with 2% of the systems comprising 100 or more hospitals. 4,063 or 67% of hospitals are affiliated with a health system, making up 75% of all hospital beds.
The definition of a health system varies. According to the AHRQ, a health system is an organization that includes at least one hospital and at least one group of physicians that provides comprehensive care (including primary and specialty care). They are connected with each other and with the hospital through common ownership or joint management. This definition does not include other provider types or other common forms of integration between providers, such as post-acute care providers and nonownership contractual relationships.
The AHA defines a system as either a multihospital system or a diversified single hospital system. Their definition includes counts of affiliated physicians. SK&A, on the other hand, defines a health system by emphasizing ownership or management of healthcare providers, including hospitals, medical offices, group practices, and nursing homes.
The Compendium of U.S. Health Systems is a suite of files that provides insight into the healthcare organization landscape. It includes data on systems, hospitals, group practices, outpatient sites, nursing homes, and home health organizations.

58% of systems have 1,000 or fewer beds
The American Hospital Association (AHA) defines a hospital system as either a multi-hospital system or a diversified single hospital system. A multi-hospital system is two or more hospitals owned, leased, sponsored, or contract-managed by a central organization. Single freestanding hospitals may be categorized as a system by bringing into membership three or more non-hospital healthcare organizations.
According to the AHA, there are 6,093 hospitals in the United States. However, Definitive Healthcare's HospitalView product tracks more than 7,300 active hospitals in the country. This discrepancy in numbers can be attributed to differences in how each organization classifies hospital types.
The number of hospital systems in the United States is not readily available. However, one source mentions that there are 1,275 unique health systems in the country. It is important to note that this number may vary depending on the specific definition of a "health system" used and the data sources employed.
Regarding bed capacity, 58% of hospital systems have 1,000 or fewer beds. This information highlights the distribution of bed capacities across hospital systems in the United States. The specific number of beds in a hospital system can vary depending on various factors, including the type of hospital, the services provided, and the region it serves.
In conclusion, the number of hospital systems and their bed capacities in the United States vary due to different classifications and data sources. While the exact count of hospital systems is unclear, understanding the distribution of bed capacities provides insights into the healthcare landscape and the range of healthcare services available across the country.

Hospitals had 919,559 staffed beds in 2022
The American healthcare system is a complex network of hospitals, health systems, and other healthcare providers. As of 2023, there were 6,093 hospitals in the United States, according to the American Hospital Association's annual survey. These hospitals vary in size and scope and are spread across different states.
One crucial aspect of hospital capacity is the number of staffed beds available. In 2022, hospitals across the United States had a total of 919,559 staffed beds. This number represents the beds available for patients in acute, long-term, and domiciliary care areas within hospitals.
The distribution of these staffed beds varies by state. For example, California recorded the highest number of staffed beds in 2022, with over 74,000 hospital beds, while Vermont had a much lower number, with only 851 beds.
The number of staffed beds in hospitals is an essential metric for understanding hospital capacity and patient care. It directly impacts the ability of hospitals to admit and treat patients, especially during times of high demand or emergencies.
Additionally, it is worth noting that the definition of a "health system" can vary. According to the AHRQ, a health system includes at least one hospital and a group of physicians providing comprehensive care, connected through common ownership or joint management. However, other sources may have different definitions, including multi-hospital systems and single hospital systems.
