The effects of climate change include floods, hurricanes, heat waves, and fires; these natural disasters can result in respiratory, cardiovascular, and psychological harm in older adults, who experience the highest morbidity and mortality during heat waves. Advanced practice registered nurses (APRNs) need education on preparing, assessing, and treating older adults for climate-change disasters, especially heat waves. This article will help APRNs understand the effects of climate-change events on the vulnerable older adults and advocates for the need to integrate health effects of climate change into curricula, practicums, policy, and research agendas.  相似文献

IntroductionA sexual assault nurse examiner role exemplifies the high-stress and highly emotional patient interactions that are often associated with burnout. The purpose of this study was to examine the frequency of burnout among sexual assault nurse examiners in North Carolina.MethodsThis cross-sectional study was an anonymous survey of practicing sexual assault nurse examiners within North Carolina using the Maslach Burnout Inventory and additional demographics. Results were analyzed with odds ratios, confidence intervals, Fisher exact, chi-square, and Kruskal Wallis tests as appropriate.ResultsAmong 95 respondents, burnout was more frequent in sexual assault nurse examiners who stopped both emergency and nurse examiner work (55.6%, odds ratio 4.41, 95% confidence interval 1.07-18.06) and in dual function nurses (both emergency and nurse examiner work, 35.7%, odds ratio 2.71, 95% confidence interval 1.04-7.06). Sexual assault nurse examiners who had a high percentage of pediatric cases (above the median of 40%) were more likely to meet burnout thresholds for emotional exhaustion scores > 26 (48.78% vs 25.93%, χ2 = 5.30, P = .02) and more likely to meet burnout thresholds for depersonalization scores > 9 (48.78% vs 24.07%, χ2 = 6.28, P = .01).DiscussionHigher frequency of burnout threshold criteria was found in those people who worked concurrently as a sexual assault nurse examiner and an emergency nurse and in those who had retired from both specialties. We also found that sexual assault nurse examiners with a higher case mix of pediatric cases had higher emotional exhaustion scores and higher depersonalization scores.  相似文献

BackgroundHamstring strain injuries are the most common type of injury in elite football and are associated with a high risk of reinjury, particularly those involving the intramuscular tendon (IMT). Limited information is available regarding the rehabilitation and return to sport (RTS) processes following such injuries. This case study describes the clinical presentation of an elite football player following IMT hamstring injury, their on- and off-pitch rehabilitation alongside performance monitoring throughout RTS and beyond.Case scenarioAn elite football player suffered a grade 2c hamstring injury during an English Premier League (EPL) match. The player underwent early post-injury management, alongside progressive off-pitch physical preparation. The ‘control-chaos continuum’ was used as a framework for on-pitch rehabilitation to prepare the player for a return to full team training and competition. Objective and subjective markers of the player's response to progressive on- and off-pitch loading were monitored throughout RTS and beyond.OutcomesThe player returned to on-pitch rehabilitation after 11 days, to full team training having achieved weekly pre-injury chronic running load outputs after 35 days and played in the EPL 40 days post-injury. The player did not suffer reinjury for the rest of the EPL season.ConclusionAn understanding the unique structural and mechanical properties of the IMT, alongside expected RTS timeframes are important to inform rehabilitation and decision-making processes post-injury. Performance and frequent load-response monitoring throughout RTS and beyond, in conjunction with practitioner experience and effective communication are critical in facilitating effective RTS and reduce risk of reinjury following IMT injury.  相似文献

AimThe aim of the study was to describe the characteristics of the Bachelor’s thesis of fourth-year nursing students at a Spanish public university, the criteria that students used to choose a topic and students’ degree of satisfaction after completing the Bachelor’s thesis.DesignQuantitative study.MethodsWe examined 420 Bachelor’s theses carried out from 2013 to 2018 and conducted an online survey among fourth-year students in the 2017–18 and 2018–19 academic years (81 completed questionnaires).ResultsThe Bachelor’s thesis took the form of a research proposal. The most frequent proposal type was a qualitative hospital-based study whose objective was to understand the experiences of adult or adolescent patients, close family members, or nurses. Students chose topics for personal reasons. Most participants reported feeling satisfied with the knowledge and skills acquired.ConclusionsStudents completing a Bachelor’s thesis in the form of a research proposal have the potential to transfer their research skills to their nursing practice.  相似文献

The objectives of this study were to factor analyze the Moral Distress Scale–Revised (MDS-R) in NICU nurses and to evaluate the relationships among dimensions of the MDS-R and the demoralization, exhaustion, and loss of motive dimensions of the Burnout Measure (BM). A total of 142 NICU nurses completed modified pen-and-paper versions of the MDS-R and BM. Exploratory and confirmatory factor analyses showed that the MDS-R-14 was a relatively good fit for the data. The compromised care dimension predicted BM demoralization (β = 0.24) and exhaustion (β = 0.22), the futile care dimension predicted BM exhaustion (β = 0.18), and the untruthful care dimension predicted BM demoralization (β = .25). Strategies to mitigate moral distress and resulting burnout in NICU nurses should address futile care, compromised care, and untruthful care.  相似文献
