ABSTRACT
Objective To evaluate the effect of FOCUS-PDCA program(find,organize,clarify,understand,se-lect,plan,do,check,act )on the prevention and control of catheter-related blood stream infection (CRBSI)in an intensive care unit(ICU).Methods Process of central venous catheterization and nursing care were analyzed by u-sing FOCUS-PDCA program,and the causes for CRBSI were found out ;a continuous quality improvement (CQI) team was established to provide training for ICU nurses,and the process was improved and supervised,virtuous cir-cle was created.Results Incidence of CRBSI decreased from 8.29‰ before FOCUS-PDCA intervention(January-December,2010)to 3.20‰ after FOCUS-PDCA intervention(January 2011 -December 2012),the difference was significant (χ2 =14.6,P <0.001).Conclusion FOCUS-PDCA program is effective for controlling the incidence of CRBSI.
ABSTRACT
DLUT4060 piezoelectric multi-component force platforms and DVM8820 three-dimensional infrared image capture system were used to test the sit-to-walk (STW) movements of 11 healthy elderly (72. 6 +/- 12. 2 years old) and 11 healthy young (19. 7 +/-1. 3 years old) individuals. Firstly, we studied the effects of seat-heights on the ground reaction forces, the velocity of the center of mass, and action time duration. Then we discussed the movement strategies and falling risks of the persons in the two age groups respectively. Finally, we decided the best seat height for the two age groups. It was found that the best seat heights for both the two age groups were 100% popliteal height. This height may make the subject get the greatest biomechanical advantages and the lowest falling risks. The popliteal height must be concerned when designing and fixing up the public activity area facilities and daily life of the elderly. To some extent, it can reduce the falling risk of the elderly.
