The aim of this study was to confirm the relationship between patient experience, patient safety knowledge, and patient safety perception and prepare basic data to help initiate patient safety activities and patient safety education in primary care institutions.
The participants were 252 patients who had used primary care institutions in the Gyeonggi area within six months prior to the study. Data were collected from February 16 to March 15, 2021 using a structured online questionnaire on patient experience, patient safety knowledge, and patient safety perception. The data were analyzed using SPSS 25.0, and hierarchical regression analysis was performed to analyze the moderating effect of patient safety knowledge.
Patient experience had a significant positive correlation with patient safety perception. In the relationship between patient experience and patient safety perception, patient safety knowledge had a significant moderating effect. In particular, among the sub-factors of the patient experience, doctors and the hospital environment significantly affected patient safety perception, and in this process, patient safety knowledge acted as a moderating variable.
Patients with low safety knowledge have a higher perception of safety when they have positive experiences through doctors. Therefore, medical staff should make continuous efforts to establish a safe hospital environment and earn patients’ trust to increase their safety perception. It is necessary to develop mandatory patient safety education programs by identifying potential patient safety problems and accidents in primary care institutions.
