Cluster analysis of self-concept and job satisfaction in Chinese nurses with master's degree to identify their turnover intention: A cross-sectional study.

AIMS AND OBJECTIVES: This study aimed to implement cluster analysis of self-concept and job satisfaction to identify subgroups in nurses with master's degree and explore the associations of turnover intention with characteristics among these clusters. DESIGN: A cross-sectional study adhering to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). METHODS: A convenience sample of 408 nurses with master's degree in China filled out the survey from 19 November 2019 to 30 December 2019. A sociodemographic questionnaire, the Nurses' Self-Concept Questionnaire (NSCQ), Job Satisfaction Scale (JSS) and Turnover Intention Questionnaire (TIQ) were adopted to collect the data. K-means cluster analysis was implemented on the R software, and data were analysed using SPSS 24.0. RESULTS: Three subgroups were identified based on cluster analysis of NSCQ and JSS subscales in 405 nurses (99.3%) available for statistical analysis, among whom 30.9%, 17% and 48.1% were allocated to these clusters respectively. Turnover intention significantly differed among the three clusters, with cluster 2 having the highest turnover intention and cluster 1 having the lowest turnover intention. Working department, position, professional title, clinical nurse specialist and annual income were factors differentiating TIQ scores in each cluster. CONCLUSIONS: This study identified three clusters of nurses with master's degree and showed that each cluster was associated with the level of turnover intention. The unique characteristics of the three clusters may be also helpful in identifying and providing specific managerial or social support to reduce turnover rates in nurses with master's degree. RELEVANCE TO CLINICAL PRACTICE: Cluster analysis is s an unsupervised machine learning method to identify meaningful subgroups within heterogeneous population based on variables distributions and patterns underlying in the data set. Through clustering, nurses with multi-dimensional characteristics could be allocated into subgroups associated with turnover intention. As a result, nursing managers could provide approaches for each subgroup to reduce turnover intention.

The effectiveness of curvilinear supine position on the incidence of pressure injuries and interface pressure among surgical patients.

BACKGROUND: Intraoperative pressure injury is still a major problem of perioperative nursing. Reducing the peak interface pressure is a valid clinical intervention for reducing the incidence of intraoperative pressure injuries. However, studies of repositioning and pressure-redistributing for surgical patients are still lacking. In this context we aimed to evaluate the effect of a curvilinear supine position on incidence of pressure injury with surgical patients in a hospital setting. METHODS: This was a prospective, randomized, controlled study, carried out from May to December 2016, included 104 surgical patients from a university hospital in China (experimental group, n = 52; control group, n = 52). Incidence of pressure injury, interface pressure, comfort and satisfaction scores from surgeons, anesthesiologists, OR nurses were recorded. Mann-Whitney U Chi-square test was used for difference of pressure injury's incidence and mixed linear model was used for interface pressure. RESULTS: Overall the intervention group had significant fewer intraoperative pressure injuries than the control group (0 patients [0%] vs. 9 patients [17.65%], p = 0.002). Compared with control group, the experimental group had significantly lower interface pressures in the sacrum and heel regions (F = 23.81, p < 0.001; F = 60.71, p < 0.001). The subjects felt comfortable in two groups were 40(80%) vs. 3(5.88%) (experimental group vs. control group), respectively (p < 0.001). CONCLUSIONS: Curvilinear supine position could significantly decrease the incidence of perioperative pressure injuries in surgical patients with surgery duration more than three hours. Considering these results, we recommend that curvilinear supine position use as effective interventions to inform perioperative care delivery, reducing perioperative pressure injuries. These findings may serve to guide the application of pressure redistribution in the surgical positioning of patients during prolonged surgery.

Effects of Curvilinear Supine Position on Tissue Interface Pressure: A Prospective Before-and-After Study.

PURPOSE: To determine whether a curvilinear supine position increases the contact area between the subject and the surgical table, reduces interface pressures within contact areas, and improves comfort. DESIGN: This observational study was completed to establish proof-of-concept to determine differences between 2 positions (supine and curvilinear) on interface pressure of 5 at-risk anatomical locations, overall contact area, and subjects' comfort level. SUBJECTS AND SETTING: The study was conducted at the operating theater of a tertiary teaching hospital in Wuhan, China. The sample comprised 145 healthy Asian volunteers between 18 and 60 years of age. METHODS: Subjects were placed in the supine and curvilinear supine positions on a surgical table. Contact area and peak interface pressures of 5 at-risk anatomical locations (occiput, scapula, sacrum, calf, and heel) were measured using a pressure mapping system, and the mean and maximum pressures of the overall contact area were calculated. Comfort was assessed by self-report using a Likert scale of 1 to 5. The Wilcoxon paired signed rank test was used to compare differences between the 2 positions, and the Spearman correlation analysis was used to identify associations among outcome variables. RESULTS: Results indicated that whole-body (overall) maximum, average interface pressures, and maximum interface pressures of the sacrum and the heel were decreased significantly, with contact area and comfort-level score increasing from 2438.71 to 2709.68 cm and 3.00 to 4.00, respectively (P < .001). Statistically significant associations were found between the contact area and measures of body morphology; correlation coefficients varied from 0.409 to 0.740 (P < .001). CONCLUSIONS: Curvilinear supine position increased overall contact area with the support surface, reduced interface pressures over contact areas (bony prominences), improved comfort, and enhanced pressure redistribution. Additional research is needed to determine if these effects will reduce intraoperative pressure injury occurrence.

Applications for radio-frequency identification technology in the perioperative setting.

We implemented a two-year project to develop a security-gated management system for the perioperative setting using radio-frequency identification (RFID) technology to enhance the management efficiency of the OR. We installed RFID readers beside the entrances to the OR and changing areas to receive and process signals from the RFID tags that we sewed into surgical scrub attire and shoes. The system also required integrating automatic access control panels, computerized lockers, light-emitting diode (LED) information screens, wireless networks, and an information system. By doing this, we are able to control the flow of personnel and materials more effectively, reduce OR costs, optimize the registration and attire-changing process for personnel, and improve management efficiency. We also anticipate this system will improve patient safety by reducing the risk of surgical site infection. Application of security-gated management systems is an important and effective way to help ensure a clean, convenient, and safe management process to manage costs in the perioperative area and promote patient safety.
