Abstract
This study aimed to investigate the influence of certified perioperative nurses on preoperative outpatient clinic and preoperative assessments. The study was conducted from February 2021 to September 2022; data were collected and analyzed using a questionnaire at 247 hospitals in Japan. To analyze the factors affecting the rate of preoperative assessment with the primary endpoint of preoperative outpatient care and preoperative nursing visits, we performed multiple linear regression analysis of facility characteristics, perioperative nurse background, and the presence or absence of certified perioperative nurses. Regarding the presence or absence of a preoperative outpatient clinic, patients from 68 (52.3%) and 41 (35.0%) institutions in the enrolled and nonenrolled groups. Respectively, underwent a preoperative assessment; the rate of preoperative assessments in the enrolled group was significantly higher than that in the nonenrolled group. Multivariate analysis of factors influencing the preoperative assessment rate revealed a significant association with certified perioperative nurse attendance. Facilities with certified perioperative nurses have a significantly higher prevalence of preoperative outpatient clinic and significantly higher rates of preoperative assessments than facilities without certified perioperative nurses. Enrollment of certified perioperative nurses may lead to the improvement of the quality of preoperative nursing interventions.
