ABSTRACT
BACKGROUND: There were few literature reports on the use of perioperative parameters to predict the risk of albumin transfusion after spinal tuberculosis surgery based on the application of nomogram and propensity score matching (PSM) analysis.
PURPOSE: The purpose was to predict the risk of albumin transfusion after spinal tuberculosis surgery based on a combination of PSM and nomogram.
METHODS: The clinical data of the patients were collected in our hospital, including preoperative clinical data, preoperative laboratory tests, and postoperative clinical data. All data were divided into two groups, including the albumin transfusion group and the non-albumin transfusion group. The PSM analysis was used to adjust the baseline data of the two groups. The nomogram was further constructed. The practicability and predictive ability of the model were evaluated.
RESULTS: A total of 494 cases were collected in this article. 102 pairs by PSM analysis were used to construct the nomogram. There were statistical differences in surgical approach, aspartate aminotransferase (AST)/ alanine aminotransferase (ALT), drainage, and kyphosis by logistic analysis, and these parameters were included in the construction of the nomogram. the C-index of the prediction model was 0.734. The area under the curve (AUC) was 0.73 and the net benefit was between 0.13 and 0.99. The calculated C-index was 0.71 by the internal verification method.
CONCLUSION: The PSM analysis had a good matching effect and the nomogram had a good predictive ability. Surgical approach, AST/ ALT, drainage, and kyphosis might be predictors of albumin transfusion after spinal tuberculosis surgery.
