Abstract
This quasi-experimental research aimed to compare acute confusion scores following the implementation of a nursing therapeutics model designed to prevent acute confusion in high-risk elderly patients admitted to the medical intensive care unit. The sample consisted of 102 high-risk elderly patients, divided equally into a control group (n = 51) and an experimental group (n = 51), selected through purposive sampling. The control group received standard nursing care, while the experimental group received care based on the developed nursing therapeutic model for the prevention of acute confusion in high-risk elderly patients. Research instruments included: (1) a personal information record form, (2) the Richmond Agitation Sedation Scale (RASS), (3) the Confusion Assessment Method for the ICU (CAM-ICU-7), and (4) the intervention tool, a nursing therapeutic care model developed by the researcher using the ABCDEF care bundle. Instrument validity was verified by five experts, yielding a Content Validity Index (CVI) of 1. Data were analyzed using descriptive statistics, Chi-square test, Fisher’s exact test, and Mann-Whitney U test. Results showed no significant difference in CAM-ICU-7 scores between the two groups on day 2 of program implementation. However, on day 3, the experimental group had significantly lower CAM-ICU-7 scores than the control group (U = 637, p < .05), indicating the effectiveness of the intervention.
