Objective: To analysis the risk factors affecting prognosis of patients with acute stroke complicated hospital-acquired pneumonia(HAP).Methods: Ninty-eight patients with acute strokes in our hospital were collected and divided into research and control groups,with 49 patients in each group,according to complicated HAP.The factors including age,systolic pressure(SP),diastolic pressure(DP),glycolated hemoglobin(HbA1c),blood cholesterol(CHOL),Chinese stroke scale scores(CSS),repeat swallow test frequency,methicillin-resistant staphylococcus aureus(MRSA) infection rate and pseudomonas aeruginosa(PA) infection rate,Candida albicans(CA) infection rate in each group were isolated and analyzed.The association of these factors with Barthel index(BI) at 1 year after strokes was investigated.The BI,recurrence rate and mortality rate were compared between the two groups.Results: The age of onset,CSS,SP,DP,HbA1c,CA infection rate,MRSA infection rate,PA infection rate were negatively correlated with BI,whereas the repeat swallow test frequency was positively correlated with BI.The CHOL had no correlation with BI.BI,recurrence rate and mortality rate were significantly different between the two groups(P0.05).Conclusion: The risk factors affecting the prognosis of patients with acute stroke complicated HAP are age,CSS,swallow function,SP,DP,HbA1c,MRSA infection rate,PA infection rate,and CA infection rate.
