Patients with non-English primary languages experience better surgical outcomes at language-serving hospitals compared to non-language-serving ones.

• Readmission rates were 2.6% at language-serving hospitals versus 5.7% at non-language-serving hospitals (p < 0.001).
• Patients at language-serving hospitals had a 56% lower chance of readmission (adjusted odds ratio: 0.44).

Understanding these differences can guide surgical practices and improve care for linguistically diverse patients in all settings.

• The study included over 28,000 patients, highlighting significant implications for patient selection and resource allocation.
