Abstract

Objective: The incidence of postoperative morbidity and mortality in hip fracture patients is high and is associated with nutritional deficiencies. This study investigated the predictive value of preoperative prognostic nutritional index (PNI) on postoperative intensive care unit (ICU) requirement and mortality in geriatric hip fracture patients.

Methods: Geriatric (≥65 years old) hip fracture patients who underwent surgery between January 2021 and September 2023 were evaluated retrospectively. Patients were classified according to the unit followed in the postoperative period (service group and ICU group) and 28-day mortality (mortality group and survivor group). The predictive value of PNI for ICU requirement and mortality and the factors affecting ICU requirement and mortality were investigated.

Results: The study included two hundred twenty-two patients, and 66.2% (n=147) were women. In the postoperative period, 47.7% (n=106) of the patients were followed in the ICU and 52.3% (n=116) in the inpatient service. The 28-day mortality of the patients was 6.8% (n=15). PNI was found to be significantly lower in patients followed in the ICU (group ICU) than in those followed in the service (group S) and in patients who died (group mortality) compared to those who lived (group survivor) (p<0.001 and p=0.029, respectively). In multivariate regression analysis, high American Society of Anesthesiologists (ASA) status and low PNI were determined to be independent risk factors for ICU requirement. Acute Physiology and Chronic Health Assessment II score was an independent predictor of mortality. In ROC curve analysis, the cut-off value of PNI in predicting mortality was 32.5, and the area under the curve was 0.660 (95% CI, 0.516-0.803).

Conclusion: In geriatric hip fracture patients, preoperative PNI value can be used, like ASA status, in determining postoperative ICU requirements. Nutritional deficiencies are associated with adverse postoperative outcomes in this patient group, and low PNI values (<32.5) help predict in-hospital mortality.

预后营养指数对老年髋部骨折患者术后重症监护需求和死亡率的预测价值。
目的:髋部骨折患者术后发病率和死亡率很高,这与营养缺乏有关。本研究探讨了术前预后营养指数(PNI)对老年髋部骨折患者术后重症监护室(ICU)需求和死亡率的预测价值:方法:对2021年1月至2023年9月期间接受手术的老年(≥65岁)髋部骨折患者进行回顾性评估。根据术后随访单位(服务组和重症监护室组)和 28 天死亡率(死亡组和存活组)对患者进行分类。研究了 PNI 对重症监护室需求和死亡率的预测价值,以及影响重症监护室需求和死亡率的因素:研究包括 222 名患者,66.2%(n=147)为女性。术后,47.7%的患者(n=106)在重症监护室随访,52.3%的患者(n=116)在住院部随访。患者的 28 天死亡率为 6.8%(15 人)。结果发现,在重症监护室接受随访的患者(ICU 组)的 PNI 明显低于在住院处接受随访的患者(S 组),死亡患者(死亡组)的 PNI 明显低于存活患者(存活组)的 PNI(P 结论:在老年髋部骨折患者中,PNI 明显低于 PNI:对于老年髋部骨折患者,术前 PNI 值与 ASA 状态一样,可用于确定术后重症监护室的需求。营养缺乏与这类患者的术后不良预后有关,而低 PNI 值 (
