Objective To study the effect of solution focused theory on improving the sleep quality of ACS patients with clinical pathway.Methods 100 ACS patients with clinical pathway in Tangshan Gongren hospital from September 2010 to January 2011 were selected as study objects,and they were randomly divided into the control group(51 cases)and the intervention group(49 cases).Then the sleep quality was assessed during the first 24 hours being admitted and on the second and forth week after the intervention with the Athens Insomnia Scale(ASI).Results At the second week after intervention,4 items of the ASI Score of the observation group were different from the control group significantly.The 4 items were nighttime sleep disruption,waking up early,evaluation of total sleep quality,effect on the day of emotion.On the forth week after intervention,only the item of effects on daytime function was not different from the control group significantly,the scores of other 7 items were significantly different from those of the observation group.Conclusions The effect of solution focused theory in improving the sleep quality of ACS patients with clinical pathway is significant,and it plays an active role in improving the state of disease.
