Abstract:
Objective To investigate the detection status and risk factors of bacterial pneumonia (BP) in elderly patients with acute ischemic stroke (AIS), and to provide evidence for the prevention and treatment of BP in elderly patients with AIS. Methods The case data of 320 elderly patients with AIS admitted to Xijing Hospital from June 2021 to June 2024 were retrospectively collected and analyzed. The distribution status of pathogenic bacteria of BP in the elderly AIS patients was statistically analyzed, and the risk factors of BP in AIS patients were explored and the predictive value was analyzed. Results Among the 320 elderly AIS patients, 57 cases (17.81%) developed BP. Multivariate logistic stepwise regression analysis showed that concurrent dysphagia [OR (95% CI) = 1.654 (1.240-2.206)], high platelet to lymphocyte ratio (PLR) [OR (95% CI) = 1.418 (1.116-1.801)], high neutrophil to lymphocyte ratio (NLR) [OR (95% CI) = 2.756 (1.197-5.360)], and acute ischemic stroke-associated pneumonia score (AIS-APS) [OR (95% CI) = 3.414 (1.574-7.405)] were independent influencing factors for BP in elderly AIS patients (P<0.05). The combination of the above four factors had the largest area under the curve (AUC) (0.866) in predicting BP in elderly AIS. Conclusion The occurrence of BP in elderly AIS patients is related to dysphagia, high level of PLR, high level of NLR, and high score of AIS-APS. It is necessary to strengthen the early identification and intervention of high-risk factors in clinical practice.
