Abstract
The Purpose of this study was to identify predictive factors influencing patient safety culture among nurse anesthetists in tertiary hospitals in the lower northern region of Thailand. The samples included 105 nurse anesthetists selected by proportionate random sampling. The questionnaire was The Patient Safety Culture Survey of the Institute for Healthcare Quality Development and Accreditation, and the Seven-Factor Safety Questionnaire developed from Vincent's seven-factor framework of safety. The Index of Item Objective Congruence (IOC) was between .60-1.00 and the reliability of the instrument was tested among 30 anesthetists with a Cronbach's Alpha Coefficient of .95 and .94, respectively. Data were analyzed using descriptive statistics and stepwise multiple regression analysis.
The results of the study found that the nurse anesthetists at the Lower North Regional Tertiary Hospital had a high mean level of safety culture ( = 3.96, SD = .32) and the overall mean of the seven-factor safety was at a high level (
= 3.93, SD = .34). The team factor had the highest mean (
= 4.14, SD = .44). The analysis of factors influencing patient safety culture of nurse anesthetists showed that factors from the seven levels of safety in all seven areas together explained 48.0% of the variance in patient safety culture (R2=.480, p<.001). The team factor significantly influenced the patient safety culture, as evidenced by statistical significance (β=. 526, P < .001).
This research recommends prioritizing teamwork development in the nurse anesthetist unit to enhance organizational effectiveness.
