Top U.S. Health Systems by Total Member Hospital Beds

Share this post

Health systems, or integrated delivery networks (IDNs), are a key component of care delivery in the U.S. These entities bring together distinct healthcare facilities under one management system—coordinating patient care and retaining revenue. Currently, there are more than 1,030 IDNs in the U.S.

Using Definitive Healthcare data, we can break down the largest U.S. healthcare systems by total staffed beds at member hospitals to better understand their financial presence, place among competitors, and operating power.

Although square footage is a useful measurement as well, the value of a hospital ultimately lies in how many patients it can take in. In total, the top 10 healthcare systems cover: 1,179 hospitals; 163,155 licensed beds; and $52.3 billion in net patient revenue.
