Status quo and development recommendations for infectious disease early warning system in public general hospitals in China / 中华医院管理杂志

Early warning of infectious disease outbreak is key to controlling epidemics. Public general hospitals can effectively play their " outpost" role in the early warning and response of infectious diseases, which is directly related to the success of epidemic prevention and control. The authors summarized the current construction and main functions of infectious disease early warning systems at national level, regional level and public general hospitals, analyzed the problems existing in such construction, and put forward targeted suggestions. As found by the authors, some public general hospitals in China have initially built an early warning system for infectious diseases, achieving early recognition, early warning and reporting of infectious diseases to some extent. However, these systems were challenged by such shortcomings as insufficient intelligence, lack of data information exchange, immature practice and application, and lack of attention to the monitoring and early warning of endemic infectious diseases. It is suggested to improve the policy and system support in the future, to expand the types of infectious diseases for monitoring and early warning, to enlarge the sources of monitoring data and to strength hospital informationization construction.

The effect of contralateral support technology on postural displacement of long-term bedridden patients after turning over / 中国实用护理杂志

Objective To study the effect of contra lateral support technology on the contra lateral postural displacement of long-term bed ridden patients and patients of inability to perform voluntary movements in clinical practice. Methods 100 eligible patients were divided into control group and experimental group according to the admission sequence. 50 patients in the control group use traditional triangle mat to turn over for every 2 hours,and 50 patients in the experimental group use combined mat to turn over at the same frequency. Postural displacement on the patient′s skin and the displacement time were observed for 24 hours and recorded for 6 times. Results The incidence rate of postural displacement, abnormal skin and the mean time of displacement of the control group were 28.67%(86/300),5.00%(15/300),(99.0 ± 18.5)min,and that of the experimental group were 65.33%(196/300),9.00% (27/300),(78.2 ± 31.6)min.The differences between both groups were statistically significant(χ2=80.958, 3.687, t=4.014, all P<0.05). Conclusions With the patient′s muscle strength increasing, the ratio of postural displacement after turning over gradually increases,and the mean time for displacement gradually decreases, increasing the damage on the skin by shear force and the risk of stress injury due to invalid position. However, the contra lateral support technology could reduce the occurrence of postural displacement to a large extent,thus decreasing risk of stress injury.
