Objective To investigate the risk factors and clinical characteristics,auxiliary examination char-acteristics,treatment and prognosis for acute stroke patients with deep vein thrombosis (DVT),in the hope of provi-ding the detailed clinical data for hospitalized patients with stroke in early prevention,early diagnosis and early treat-ment of DVT.Methods 160 cases of stroke patients were reviewed including 66 cases of patients with hemiplegia after stroke and ultrasound confirmed DVT data analysis,And compared with the same period of 94 cases of DVT in patients with stroke.The purpose of this study was to evaluate the incidence of DVT,possible risk factors,and clinical characteristics.Results Stroke in patients with DVT spent an average of 16d.DVT occurred in elderly patients (65 years or higher) with 44 cases,accounting for 66.67%;Serious paralytic 42 cases (72.72%),long-term bed 52 cases (78.78%);The most commonly comorbid disease was diabetes mellitus,hypertension and hyperlipidemia;The plasma fibrinogen concentration was (5.02 ±1.38) g/L,which was significantly higher than (2.74 ±1.65) g/L of the control group.Compared with control group,the difference was statistically significant (t=4.78,P<0.01). Conclusion Limb paralysis,long-term lie in bed,older age and high condensation state are DVT risk factors,which should be paid to prevent in advance clinically.

Objective This article seeks to apply root cause analysis (RCA) to identify the fundamental cause of low hand hygiene compliance among medical personnel, and try to evaluate the effect of interventions. Methods Using RCA method to analyze the direct cause of hand hygiene compliance among medical personnel ,and then find out the root cause of it. It's expected that the hand hygiene compliance of medical personnel shall be improved through pro-posed interventions. Results After the intervenetions,the rate of hand hygiene compliance from 25.73% to 42.79%(P<0.01). Comparison with the actual rates of WHO five times hand washing, there were notable differences(P<0.05) in observation ofcontacting patient beforehand, contacting patient afterwards and prior to aseptic operations through three interventions. In fact, there were no differences between contacting the patients' blood and body fluids and contacting the patients'surroundings afterwards. Conclusion Using RCA methods to search for the root cause of low hand hygiene compliances among medical personnel. Through proposed interventions,hand hygiene compliances of medical personnel could be enormously improved.
