Learning Objective 1: The learner will be able to discuss the factors predicting knowledge level and assessment ability for delirium among nurses.
Learning Objective 2: The learner will be able to discuss the needs for further research on clinical settings to improve nursing management for delirium.
The purpose of this study was to identify the factors influencing knowledge level and assessment ability for delirium among nurses. The subjects of this study were 272 nurses in general hospitals who have had more than 6 months of nursing experience. The data were collected by structured questionnaire from September 27 to October 8 of 2010 and analyzed by the SPSS WIN 18.0 program using percentages, means, t-test, ANOVA, Pearson correlation coefficients, and multiple regression. The total mean score (SD) for knowledge level of delirium was 31.73 (4.67), and at each domain, the participants scored 9.01 (1.25) for etiology, 12.52 (2.59) for sign and symptom, 10.20 (2.29) for nursing management. The mean score (SD) of the perceived ability of delirium assessment was 48.99 (18.87). There were significant differences of knowledge level of delirium according to the age (F=3.256, p=.022), marital status (t=2.618, p=.009), educational level (F=3.935, p=.021), periods of work (F=4.329, p=.014), work position (t=-2.245, p=.026), previous experience of delirium education (t=3.424, p=.001), previous experience of delirium education (t=2.180, p=.030), and perceived ability of delirium assessment (F=4.854, p=.001). In multivariate approach, factors included in this study explained 6.9% of variance in knowledge level and 22.8% of variance in perceived ability of delirium assessment. Previous experience of delirium education (β=.194), perceived necessity of delirium education (β=.153), and work position (β=.129) were significantly affecting knowledge level of delirium. Significant predictors of perceived ability of delirium assessment were opportunities of delirium education (β=.326), experience of providing care to the patients with delirium (β=.218), working duration as nurses (β=.143), and knowledge level of delirium (β=.125). Based on these findings, it is needed that not only developments of educational programs but also provide continuous education concerned about management for delirium to improve the management abilities of nurses for patients with delirium.
