Objective To investigate the current situation and risk factors of"socialized hospitalization"in elderly stroke patients.Methods A total of 329 elderly stroke patients who were admitted to No.971 Hospital of PLA Navy from January 2022 to December 2022 were enrolled in this retrospective study.The patients without"socialized hospitalization"were assigned to the control group(n=258),and those with"socialized hospitalization"were assigned to observation group(n=71).The age,gender,admission route,department transfer during hospitalization,hospital-acquired infection,depressive symptoms,cognitive impairment,activity of daily living(ADL)level at discharge were compared between the two groups.Multivariate logistic regression analysis was used to analyze the risk factors of"socialized hospitalization"in elderly stroke patients.Results There were no significant differences in gender,age,route of admission,or department transfer during hospitalization between the two groups(P>0.05).The proportions of patients with hospital-acquired infections,cognitive impairment,depressive symptoms and ADL meeting discharge standards in the observation group were higher than those in the control group(P<0.05).Multivariate logistic regression analysis showed that hospital-acquired infections,depressive symptoms and severe ADL level at discharge were independent risk factors for"socialized hospitalization"in elderly stroke patients(P<0.05).Conclusion There is a high proportion of"socialized hospitalization"in elderly patients with stroke.The main risk factors are hospital-acquired infection,cognitive impairment,depressive symptoms and ADL level at discharge.Active and effective measures should be taken to deal with them.

Objective To analyze the characteristics of quantitative electroencephalogram(qEEG)parameters in patients with acute ischemic stroke.Methods The clinical data of 81 AIS patients who were admitted to No.971 Hospital of PLA Navy from August 2022 to August 2023 and 68 healthy controls were collected.All the subjects were examined by qEEG.Stroke patients were assessed by National Institutes of Health Stroke Scale(NIHSS)and the locations of infarction were determined by imaging examination.Basic data and qEEG parameters were compared between AIS patients and healthy controls.The qEEG parameters were compared in AIS patients with different NIHSS scores,infarction sites,anterior or posterior circulation.The correlations between qEEG parameters and NIHSS scores were analyzed.Results The δ and θ wave power values,DAR(δ/α)and DTABR([δ+θ]/[α+β])values of qEEG in AIS patients were significantly higher than those in the healthy controls(all P<0.05).The values of DAR and DTABR in patients with NIHSS>5 were higher than those in patients with NIHSS≤5(P<0.05).The δ,θ and β wave power in patients with subcortical infarction were significantly higher than those in patients with brainstem infarction(all P<0.05).There were no significant differences in qEEG parameters between patients with anterior and posterior circulation.Pearson correlation analysis showed that DAR and DTABR values were positively correlated with NIHSS score(P<0.05).Conclusion AIS can affect the changes of qEEG parameters.qEEG parameters are related to neurological impairment in AIS patients,which may help to evaluate neurological impairment in patients with stroke.
