Relationship between PNI and NPS score.

ObjectivesThis study aimed to evaluate and compare the clinical predictive value of prognostic nutritional index (PNI) and naples prognostic score (NPS) as biomarkers for the prognosis of incisional wound healing in patients who underwent thoracolumbar tuberculosis surgery through the posterior approach.MethodsFrom January 2019 to October 2021, a total of 124 patients with thoracolumbar tuberculosis who underwent posterior approach debridement and internal fixation were included in this study. We retrospectively analyzed the clinical data, including PNI and NPS. They were divided into poor wound healing (PWH) and non-PWH groups according to whether PWH developed after the operation. And according to the receiver operating characteristic curve, patients were divided into two groups through the threshold value. Risk factors were found using logistic regression analysis.ResultsThe unfavorable outcome group had lower hemoglobin, serum albumin, Pre-albumin, PNI, and higher estimated blood loss, instrumented segments, neutrophil count, and NPS (P ConclusionBoth PNI and NPS might be novel independent biomarkers and predictors of poor outcomes in incisional wound healing after STB surgery.
