Neutrophil Phenotypic Profiling and Surgical Site Infections in Surgical Patients

March 16, 2026 updated by: Koichi Yuki, Boston Children's Hospital
Surgical site infections (SSIs) are one of the major hospital acquired infections and responsible for the most cost among the hospital acquired infections. The objective of this study is to assess the neutrophil functional profiles and their associations with SSIs.
