Fluctuations in Detection Indicators and Their Significance for the Diagnosis of Early Pressure Injury in Rat Models.

PURPOSE: The aim of this study was to identify the most meaningful diagnostic indicator for distinguishing blanchable erythema (BE) and stage 1 pressure injury (early PI) in an in vivo (rat) model. DESIGN: A prospective case-control design was used to complete a horizontal and vertical comparison of detection indicators during the process of fading of BE or the deterioration of early PI into ulcer in rat models. MATERIALS AND SETTING: The sample comprised 5 hairless rats with 20 injuries, of which 10 were BE and the other 10 were early PI. Data were collected at Nagano College of Nursing in 2020 in Nagano, Japan. METHODS: The BE and PI rat models were established by subjecting the dorsal skin of a hairless rat to compression between 2 neodymium magnets for 45 minutes and 3.45 hours, respectively. The affected skin was observed based on the following: (1) photography, (2) hardness, (3) temperature, (4) moisture, and (5) spectrophotometric (a* value and ultraviolet [UV] reflectance) measurements. All measurements of BE were performed at the beginning to 60 minutes after decompression, and those for early PI were performed until 48 hours after decompression. RESULTS: Multiple BE factors, such as the degree of erythema (macroscopy and a* value), hardness, temperature, and moisture, were found to have unstable fluctuations. Only UV reflectance gradually decreased from 6 hours and decreased significantly at 48 hours after decompression (P = .001 vs 1 hour). In contrast to early PI, erythema in BE obviously faded within 10 minutes. CONCLUSIONS: Study findings indicate that a continuous decrease in UV reflectance can reflect the worsening of hemorrhage in early (stage 1) PI. In contrast, other indicators including photography, skin hardness, temperature, and moisture fluctuated and did not prove predictive for PI progression. The obvious fading of erythema in BE a short time after decompression can be used for clinical observations.

Thermal preconditioning can reduce the incidence of intraoperatively acquired pressure injuries.

Intraoperatively acquired pressure injuries (IAPIs) occur frequently among patients who undergo surgical procedures that last longer than 3 h. Several studies indicated that heat shock proteins (HSPs) play an important role in the protection of stress-induced damages in skin tissues. Hence, the aim of this study was to investigate the potential preventive effect of thermal preconditioning (TPC) on IAPIs in surgical patients and rats and to identify the differentially expressed HSP genes in response to the above treatment. TPC was performed on one group of hairless rats before the model of pressure injuries was established. Subsequently, the size of skin lesions was measured and the expression levels of mRNA and protein of HSPs of the pressured skin were detected by real-time polymerase chain reaction (RT-PCR), western blot, and immunohistochemical staining. For human studies, 118 surgical patients were randomly divided into the TPC group (n = 59) and the control group (n = 59), respectively. The temperature and pressure of sacral skin, as well as the incidence of pressure injury (PI) were detected and compared. In animal studies, TPC significantly reduced both the size and incidence of PI in rats on the second, third and fourth days post treatment. In addition, the expression levels of both mRNA and protein of HSP27 were increased in the TPC group, compared with the control group. Immunohistochemical staining showed that HSP27 was distributed in various types of dermal cells and increased in basal cells. In human studies, a significant reduction (75%) of IAPIs was observed among the patients in the TPC group. TPC can reduce the incidence of PI in rats and humans, and the upregulation of HSP27 may play an important role in this biological progress. Further studies are warranted to explore the molecular mechanism of the preventive effect in PI mediated by HSP27.

Predicting the different progressions of early pressure injury by ultraviolet photography in rat models.

Early pressure injury (PI) can result in either spontaneous healing (SH) or deterioration into ulcer (DU). However, determining whether PI will progress into SH or DU on the basis of non-blanchable erythema only is difficult. In this study, we constructed two animal PI models to mimic SH and DU injuries and observed haemorrhage by using ultraviolet (UV) photography to develop potential clinical indicators for predicting the progression of early PI. Macroscopy, UV photography, and skin temperature observations were obtained. In the SH group, macroscopic observation showed the erythema was obvious at 0.5 hours after decompression and faded gradually had almost disappeared at 72 hours. In the DU group, the erythema persisted, and an erosion appeared at 24 hours after decompression and expanded at 36 hours. The erythema developed into an obvious ulcer at 48 hours and enlarged at 72 hours. The obvious ulcer found at 48 hours through macroscopic observation was clearly visible at 36 hours with UV photography, and a significant difference in grey values between the two groups was found at as early as 18 hours (P < .05). This study provided evidence showing that UV photography can predict the different progression stages of early PI. Additionally, when combined with the transparent disc method, UV photography also can be used to identify the circulatory disorders of early PI, such as haemorrhage or hyperaemia and even congestion.

Demand Analysis of Telenursing for Community-Dwelling Empty-Nest Elderly Based on the Kano Model.

Background: In recent years, the increasing number of empty-nest elderly has become a significant global social problem, and the rapid development of medical technology and information technology has improved the feasibility of telenursing. However, few studies have been conducted on needs of telenursing among the empty-nest elderly. The aim of this study is to explore the needs of telenursing for community-dwelling empty-nest elderly who are completely independent in activities of daily living (ADL), or who are mildly disabled, and to provide a reference for improving the remote care quality. Methods: A questionnaire survey aiming to explore telenursing needs of the elderly was conducted among 268 community-dwelling empty-nest elderly who were selected using random sampling and then data were analyzed based on the Kano Model. Results: Chi-square goodness-of-fit test showed that there were significant differences between actual and expected counts for each item of telenursing needs (p < 0.01 for all), indicating that the sample had specific individual preference for the Kano category. The desired degree of telenursing service ranged from 48.37% to 80.86%, the better values (satisfaction) were between 57.09% and 67.56%, and the worse values (dissatisfaction) were between 11.92% and 37.93%. The items, remote one-button emergency caller and remote emergency assistance arrangement, were considered to be one-dimensional qualities by empty nesters and the rest were attractive qualities. In the quadrant analysis diagram, all the remote care services were categorized as attractive qualities. Discussion: The community-dwelling empty-nest elderly with ADL independence or mild impairment have positive attitudes toward telenursing services, especially the needs of remote first aid nursing. Medical policy makers and nursing managers can provide targeted telenursing services according to empty nesters' requirements, thus improving nursing care quality and satisfaction of the elderly.

Intervention effects of telenursing based on M-O-A model in empty-nest older adult individuals with chronic diseases: a randomized controlled trial.

Aim: This study aims to verify the effectiveness of M-O-A telenursing intervention model in improving the health status and quality of life of the empty-nest older adult individuals with chronic diseases by a randomized comparative trial. Methods: M-O-A telenursing intervention model was constructed based on the needs of the participants. The control group (N = 39) received routine nursing, the experimental group (N = 39) received M-O-A telenursing intervention in addition to routine nursing. After 12 weeks of intervention, the intervention effects of being a participant in the two groups were evaluated. SPSS 26.0 was used for data analysis. Results: After 12 weeks of intervention, for the experimental group, each dimension of quality of life based on EQ-5D-3L became better, especially for "pain/discomfort," "anxiety/depression," "HRQoL" and "EQ-VAS" (all p < 0.05) and each dimension of quality of life based on SF-36 became better too, especially for "GH," "BP," "RE," "MH," "VT," "SF," "PCS," "MCS," "SF-36" (all p < 0.05). In addition, there was a statistical downward trend in blood pressure, blood glucose, weight, BMI, fat rate, nap duration, number of nocturnal awakenings, light sleep rate and a statistical upward trend in water rate, basal metabolic rate, nighttime sleep duration, deep sleep rate, rapid eye movement sleep rate, especially at the end of intervention (all p < 0.05). While for the control group, there was no statistical improvement in all these aspects. Conclusion: The M-O-A telenursing model could effectively regulate quality of life and health condition of the empty-nest older adult individuals with chronic diseases, making it worthy of further promotion and application.

Exploring the relationship between lateral violence and nursing professionalism through the mediating effect of professional identity: A cross-sectional questionnaire study.

AIM: This study aimed to investigate the prevalence of lateral violence (LV) experienced by nursing students during their internship, explore the difference between professional identity and professionalism among nursing students who had or had not experienced LV and analyse the mediating effect of professional identity on the relationship between LV and professionalism. DESIGN: A cross-sectional survey was used. METHODS: An online anonymous survey was distributed to nursing students (N = 298) in Jiangsu province, China from June to July 2021. The questionnaire consisted of sections on lateral violence, professional identity and nursing professionalism. RESULTS: Approximately 49.7% of the nursing students experienced LV behaviour during the internship period. Students who experienced LV had lower professional identity and professionalism than those who did not. Among the students, LV was negatively correlated with professional identity (r = -0.333, p < 0.001) and professionalism (r = -0.418, p < 0.001). The relationship effect of LV on nursing professionalism was partly mediated by professional identity. CONCLUSION: Nearly half of the nursing students suffered from LV in the workplace, and this condition remarkably influenced nursing professionalism through professional identity. Both quantitative and qualitative studies are needed to investigate the factors that influence LV development in detail.

Psychological Impact and Compliance with Staying at Home of the Public to COVID-19 Outbreak during Chinese Spring Festival.

In December 2019, COVID-19 was reported in Wuhan, China. Most of the studies related to the psychological impact and compliance with staying at home due to COVID-19 focused on ten days or one month after the initial "stay-at-home" phase of the COVID-19 pandemic. The early psychological impact and behavior change to COVID-19 during the Chinese Spring Festival (the start time for recommendations to stay at home) is uncertain. In this study, people from 23 provinces in China were recruited to participate in an online survey, using Credamo. Psychological impact and compliance with staying at home were evaluated by a self-designed and validated questionnaire. The results indicated that anxiety was the most often reported feeling (mean: 3.69), followed by sadness (mean: 3.63). Participants employed in foreign-owned companies were most likely to express anxiety and sadness. Overall, 61.8% of participants reported hardly going out, whereas 2.4% said they frequently went out during the initial "stay-at-home" phase of the COVID-19 pandemic. Participants with higher levels of anxiety and sadness were most likely to stay at home against the spread of COVID-19, as were female gender. This survey is an important study of the first reaction to staying at home during the initial "stay-at-home" phase coinciding with Chinese Spring Festival. Our findings identified factors associated with higher level of psychological impact and better compliance with staying at home recommendations during Chinese Spring Festival. The findings can be used to formulate precaution interventions to improve the mental health of vulnerable groups and high uptake of policy during the COVID-19 epidemic.

Demand analysis of telenursing among empty-nest elderly individuals with chronic diseases based on the Kano model.

Aim: The increase in empty-nest elderly individuals with chronic diseases poses a major challenge to the provision of public health services in China. Telenursing can effectively relieve the pressure of public health services to a certain extent. This study aims to explore the telenursing needs of empty-nest elderly individuals with chronic diseases based on the Kano model to provide references for improving the quality of telenursing. Methods: Participants were selected from five rural communities and five urban communities in Yangzhou and Nantong, Jiangsu Province, China. A total of 348 empty-nest elderly individuals with chronic diseases were included. The participants received a sociodemographic characteristics questionnaire, and their telenursing needs were surveyed and analyzed based on the Kano model. Results: Of the 15 quality attributes evaluated by the participants, 3 telenursing services were categorized as "must-be quality", 5 were categorized as "one-dimensional quality", 5 were categorized as "attractive quality", and 2 were categorized as "indifferent quality". The proportion of individuals who desired telenursing services ranged from 47.41 to 83.62%, the better values (satisfaction) ranged from 35.29-83.98%, and the worse values (dissatisfaction) ranged from 10.91 to 63.27%. There were no significant differences in any items of telenursing needs for between participants in Yangzhou and Nantong (all P > 0.05), and there were also no significant differences in all items between rural and urban communities (all P > 0.05). Conclusion: Based on the Kano model, it was found that empty-nest elderly individuals with chronic diseases had a positive attitude toward telenursing and that they had different levels of need for different telenursing services. These findings provided a theoretical basis for medical decision-makers to formulate medical policies and provided a scientific foundation for nursing managers to improve telenursing services to meet the needs of the empty-nest elderly individuals with chronic diseases.

Reliability and validity of the Chinese version of Oldenburg Burnout Inventory for Chinese nurses.

AIM: This study aims to develop a reliable and validate Chinese version of Oldenburg Burnout Inventory (OLBI). DESIGN: A cross-sectional validation design was adopted in this study. METHODS: After obtaining the copyright by contacting with the author, the original English OLBI was developed to Chinese by forward translation, back-translation, cultural adaptation and a pre-test (20 nurses). The Chinese OLBI and Maslach Burnout Inventory (MBI) were administered to 641 clinical nurses during July and August, 2020. Internal consistency (Cronbach's α coefficient), split reliability (split half coefficient), construct validity (confirmatory factor analysis) and criterion validity (comparison with MBI, using Pearson correlation analysis) were assessed. RESULTS: The Chinese OLBI included 16 items. Exploratory factor analysis extracted two factors with a cumulative contribution of 62.245%. Two-dimensional structure (exhaustion and disengagement) was confirmed. It has good internal consistency (Cronbach's α coefficient values of 0.905, 0.933 and 0.876 for the total questionnaire, exhaustion dimension and disengagement dimension, respectively), split half reliability (split half coefficient = 0.883, p < .01) and criterion validity (r = 0.873, p < .01). Pearson coefficients between 16 items and the scale varied from 0.479-0.765. An acceptable model fit (χ2 /df = 2.49, RMSEA = 0.068, TLI = 0.906, CFI = 0.922, SRMR = 0.061) was achieved.

The mediating effect of self-efficacy on the relationship between family functioning and quality of life among elders with chronic diseases.

AIM: To explore whether self-efficacy has any positive or negative mediating effects between family functioning and quality of life among elders with chronic diseases. DESIGN: A cross-sectional study. METHODS: Questionnaires were collected from 516 community-dwelling elderly individuals with chronic diseases using a convenience sampling method. The questionnaires included the Self-efficacy for Managing Chronic Disease Six-Item Scale, the Family Adaptation Partnership Growth Affection Resolve Index and the MOS 36-Item Short Form Health Survey. RESULTS: Family functioning and self-efficacy impacted the quality of life of community-dwelling elderly individuals with chronic diseases. Family functioning was mediated by self-efficacy and had an indirect impact on quality of life. The mediating effect accounted for 62.50% of the total effect.
