ABSTRACT
Objective:To develop a geriatric nursing core literacy evaluation scale and to test its validity and reliability.Methods:The scale item pool was constructed by referring to relevant literatures and expert consultation method was used to form initial scale. A preliminary investigation was conducted among 40 nurses to form the formal scale, and then 252 nurses were selected to test the validity and reliability of the formal scale.Results:The formal scale consisted of four dimensions and 37 items. The Cronbach α coefficient of the formal scale was 0.980, the content validity index was 0.912, exploratory factor analysis identified 4 principal factors (knowledge geriatric nursing core literacy, skill geriatric nursing core literacy, cognitive geriatric nursing core literacy, belief geriatric nursing core literacy) and explained 73.135% of the total variance.Conclusion:The geriatric nursing core literacy evaluation scale has good reliability and validity, which can be used to evaluate the geriatric nursing core literacy of nursing staffs.
ABSTRACT
Objective To investigate the effect of different doses of pralidoxime chloride on clinical outcome including recovery rate and mortality in patients with acute organophosphorus pesticide poisoning.Methods According to the total amount of pralidoxime chloride administered over the first 24 hours or entire duration of hospitalization,a cohort of 163 organophosphorus pesticide poisoning patients,admitted from February 2004 to December 2014 were assigned to different groups followed by a retrospective analysis.Comparisons of recovery rate,mortality rate,mean length of hospital stay,and duration of mechanical ventilation were made among groups.SPSS 18.0 was used to analyze categorical variables between the data of groups with x2 test/Fisher exact probability method and numerical variables with t test or One-way ANOVA,and statistical significance was set as P ＜ 0.05.Results According to the amount of pralidoxime chloride given over the first 24 hours,the recovery rate and the mortality rate were significantly improved in the experimental group (pralidoxime chloride ＞ 2 g) than in the control group (pralidoxime chloride ＜ 2 g) (P =0.04).There was no significant difference in mean length of hospital stay between the experimental group and the control group (P =0.171),and there were statistically significant differences in recovery rate and mortality rate among the four dose-response subgroups (total dosage administered in 24 hours in group A ＜ 1 g,in group B ＜2 g,in group C ＜4 g and in group D ＞4 g) (P =0.034).Based on the total amount of pralidoxime chloride prescribed in the entire duration of hospital stay,the recovery rate and mortality rate were significantly better in the experimental group than those in control group (P =0.002),and among the three dose-response subgroups,the significant difference in recovery rate and mortality rate were also observed (P =0.006).Conclusions Increased amounts of pralidoxime chloride prescribed in the first 24 hours and in the whole hospitalized period can improve the recovery rate and reduce the mortality rate in organophosphorus pesticide poisoning patients.
