Preoperative Prognostic Nutritional Index as a Useful Tool for Predicting Postoperative Delirium in Elderly Patients with Degenerative Lumbar Diseases.
Purpose: The high incidence of postoperative delirium (POD) among patients undergoing lumbar spine surgery presents a significant barrier to achieving enhanced postoperative recovery. Accordingly, a thorough understanding and precise identification of common risk factors for POD in this surgical context are crucial to mitigating its occurrence and facilitating improved recovery outcomes. This study is the first to assess the predictive value of the Prognostic Nutritional Index (PNI) for POD in elderly patients undergoing transforaminal lumbar interbody fusion (TLIF) for degenerative lumbar spine disease.
Methods: We conducted a retrospective analysis of the outcomes of TLIF surgery in elderly patients with degenerative lumbar spine disease between 2020 and 2024. The diagnosis of POD was based on postoperative medical records during hospitalization, using the Confusion Assessment Method. The PNI was calculated based on preoperative serum albumin levels and total lymphocyte counts. Multivariate logistic regression analysis was performed to evaluate the relationship between preoperative PNI scores and the occurrence of POD. Finally, the optimal PNI cut-off point for predicting POD was determined using the receiver operating characteristic curve.
Results: POD was observed in 61 of 370 patients, with PNI being significantly lower in the delirium group. The mean PNI values were 43.02±3.44 in the non-delirium group and 48.53±3.72 in the delirium group. Multivariate logistic regression analysis revealed that low PNI (OR: 0.743; 95% CI: 0.597-0.924; p = 0.008), low serum albumin levels (OR: 0.759; 95% CI: 0.584-0.987; p = 0.040), and advanced age (OR: 1.096; 95% CI: 1.030-1.166; p = 0.004) were independent predictors of POD following TLIF. The area under the curve (AUC) for PNI on the receiver operating characteristic curve was 0.864±0.025. The cutoff value for PNI, determined using the Youden index, was 45.825, with a sensitivity of 82.0% and a specificity of 74.4%.
Conclusion: The preoperative use of PNI holds promise as a valuable tool for assessing the risk of POD in elderly patients undergoing TLIF.

Therapeutics and Clinical Risk Management is an international, peer-reviewed journal of clinical therapeutics and risk management, focusing on concise rapid reporting of clinical studies in all therapeutic areas, outcomes, safety, and programs for the effective, safe, and sustained use of medicines, therapeutic and surgical interventions in all clinical areas.
The journal welcomes submissions covering original research, clinical and epidemiological studies, reviews, guidelines, expert opinion and commentary. The journal will consider case reports but only if they make a valuable and original contribution to the literature.
As of 18th March 2019, Therapeutics and Clinical Risk Management will no longer consider meta-analyses for publication.
The journal does not accept study protocols, animal-based or cell line-based studies.
