Study on the prognostic value of PAR combined with NRS 2002 in elderly patients with pulmonary infection under the combined mode of medical care and nursing
Objective To analyze the risk factors of pulmonary infection in the elderly under the combined mode of medi-cal and nursing care,and explore the influence of the ratio of procalcitonin to albumin combined with nutritional status on the prognosis of the elderly,so as to facilitate early intervention and reduce the occurrence of adverse prognosis.Methods The clinical data of 146 elderly patients with pulmonary infection from April 2017 to August 2021 in the Sec-ond Hospital of Shandong University were retrospectively analyzed.The elderly were divided into survival group(n=99)and death group(n=47)according to their prognosis at 28 days.SPSS 22.0 statistical software was used for data analy-sis.Logistics regression analysis was performed on the related factors affecting the prognosis of the elderly with pulmonary infection at 28 d,and an ROC curve was drawn to analyze the predictive value of the related factors on the prognosis.Re-sults Procalcitonin to albumin ratio(PAR)and nutritional risk screening 2002(NRS 2002)in the death group were significantly higher than those in the survival group(P<0.05).PAR(OR=1.938,95%CI:1.033-3.638),NRS 2002(OR=2.443,95%CI:1.280-4.663)were independent influencing factors affecting the prognosis of lung infec-tion at 28 days.The area under the ROC curve for PAR and NRS 2002 to predict the prognosis of elderly patients with pulmonary infection were 0.719 and 0.613,respectively.PAR's optimal cut-off point was 0.031,with a sensitivity of 46.8%and a specificity of 87.9%,and NRS 2002's optimal cut-off point was 5.5,with a sensitivity of 74.5%and a specificity of 47.5%.The combined AUC was 0.732,the sensitivity was 61.7%,and the specificity was 83.7%,which was better than the prediction ability of a single index.Conclusion PCT,ALB,PAR,and NRS 2002 can predict the severity of lung infection in the elderly.PAR and NRS 2002 are independent risk factors for the prognosis of the elderly with lung infection at 28 days,and their combination has high clinical value in predicting the prognosis.
