Does every hospital in the US have research?

Not every hospital in the United States has a research department or conducts research. While many larger or academic hospitals are involved in medical research, smaller community hospitals typically focus on patient care and may collaborate with larger research institutions if needed. The presence of a research program or department in a hospital often depends on various factors such as location within a university or educational institution, specialized medical areas, partnerships with academic medical centers, funding availability, and institutional philosophy.
