Abstract: Objective To apply physical restraint reduction interventions based on 6 Core Strategies in order to reduce the utilization rate of physical restraint among patients in ICU. Methods A total of 426 patients admitted to ICU of the hospital from January to December 2018 were selected as the subjects, of which 208 patients admitted from January to June were the control group and 218 patients admitted from July to December 2018 were the experimental group, who were treated with the physical restraint reduction intervention. We recorded the changes in the utilization rate of physical restraint,the duration of the physicalrestraint, and the rate of unplanned extubation between two groups. Results After applying the physical restraint reduction interventions in experimental group,the utilization rate of physical restraint decreased significantly from 31.25% to 20.18%(P<0.05). The duration of physical restraint among patients in ICU decreased from 25.00 (11.00,118.25) h to 10.50 (5.00,18.75) h,the difference was statistically significant(P<0.05).Meanwhile, the rate of unplanned extubation decreased from 5.29% to 4.13%,but the difference was not significant(P>0.05). Conclusion The physical restraint reduction interventions based on 6 Core Strategies reduce the utilization rate of physical restraint and the duration of the physical restraint among patients in ICU but do not increase the rate of unplanned extubation.
