Abstract:
Objective To evaluate the risk factors of delirium in patients of intensive care unit ( ICU) by different scale systems.Methods Totals of 440 patients were enrolled in this investigation.Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Intensive Care Delirium Screening Checklist ( ICDSC) were used when patients in-and out-ICU.Other risk factors and APACHE Ⅱ score were recorded. Multiple linear regression was done between each scale and all risk factors.Results The scores of APACHEⅡ, SAS,SDS and ICDSC were (9.8 ±3.2), (43.8 ±11.3), (43.1 ±10.8) and (2.43 ±2.00) when patients discharged from ICU.Those values were (17.3 ±5.5), (48.3 ±12.7), (48.5 ±12.3) and (1.36 ±0.81) when patients first admitted to ICU.There were significant differences ( t =7.549,3.004,3.780,-3.329, respectively;P<0.05).Multiple linear regression analysis showed that the score of SAS was correlated with duration in ICU, APACHEⅡscore and drainage catheter amount (R2 =0.515,F=14.139,P<0.001).The score of SDS was correlated with duration in ICU and drainage catheter amount ( R2 =0.444,F=16.395,P<0.001) .The score of ICDSC was correlated with education, duration in ICU, duration of mechanical ventilation and APACHEⅡscore (R2 =0.803,F=39.769,P<0.001).Conclusions The sensitivity of ICDSC is high and can be used to screen delirium in ICU.The incidence of delirium increases with the duration of ICU stays.
