目的 分析子宫腺肌症可能对患者造成的心理影响,探讨子宫腺肌症患者的心理护理方法,观察护理效果。方法 将62例子宫腺肌症患者随机分配为常规护理干预组和心理护理干预组,每组31例。对常规护理干预组患者,实施常规护理干预措施。对心理护理干预组患者,在常规护理干预措施的基础上,进一步对其实施针对性的心理护理干预措施。结果 心理护理干预组患者的焦虑自评量表(SAS)评分、抑郁自评量表(SDS)评分,以及睡眠质量自评量表(SRSS)各维度评分,都明显低于常规护理干预组,差异具有统计学意义。心理护理干预组患者的生活质量综合评定量表(GQOLI-74)各维度评分,要显著的高于常规护理干预组,差异同样具有统计学意义。结论 应重视并切实做好对子宫腺肌症患者的心理护理工作,这能够有效缓解患者的焦虑、抑郁情绪,提高患者的心理健康水平,改善患者的水平及生活质量。 相似文献

The scope of computerized simulation in competency-based maxillofacial training: a systematic review
《International journal of oral and maxillofacial surgery》2022,51(8):1101-1110
Oral and maxillofacial surgery (OMS) teaching is set to undergo a paradigm shift towards competency-based training. With increasing focus on resident skill development and patient safety, computerized simulators are likely to play a more mainstream role in OMS training. A systematic review of the available literature was conducted, in accordance with the PRISMA guidelines, to highlight the scope of computerized simulation in OMS teaching. A PubMed search was performed by two independent reviewers, and 35 articles published in English between 2010 and 2021 that reported the use of computerized simulation for teaching maxillofacial procedures were included in the analysis. Eight articles on minor oral surgery, seven on orthognathic surgery, five on maxillofacial trauma, five on cleft lip and palate surgery, three articles each on nerve block techniques, endoscopic procedures, and reconstructive surgery, and one article on fibre-optic intubation reported the use of computerized simulation that can be applied to OMS training. Ten randomized controlled trials were identified in the search. However there was marked heterogeneity among the studies. Simulator training for skill acquisition mentored by an expert OMS educator could offer holistic resident training; however more studies that test common themes of resident training such as knowledge acquisition and skill development are necessary. 相似文献

《Radiography》2021,27(4):1094-1098
IntroductionEducation and training strategies in Therapeutic Radiography are challenged in recruiting and retaining students in the profession. Clinical oncology centres are often viewed as stressful environments for students due to rapid advances in technology and reported bullying and harassment. Educators continue to work with clinical partners in developing strategies to promote resilience and reduce negative attitudes. The overall aim of this project was to explore the use of Triple R sessions as a new method of student reflection.MethodsThe Review, Reflect and Re-focus (Triple R) sessions were designed to enable students to learn from their clinical experiences and; apply their understanding and positivity when they return to clinical placement. Eleven sessions were completed across 7 student cohorts in one academic year. Qualitative data was collected from feedback forms, as well as academic field notes, and analysed thematically.ResultsTwo main themes focused on: (1) staff interactions and (2) student expectations. Results showed that Triple R sessions were helpful in drawing out the experiences of students in a positive way to reflect on their own development. The sessions enabled critical self-analysis and improved problem-solving skills, particularly evident during peer discussions.ConclusionTriple R sessions explored the influence of a positive approach on students' perceptions of their overall placement. Evaluation of the data indicated that, following academic and peer discussion, students' perceptions tended to be a more positive overall view of their placement.Implications for practiceTriple R sessions can be used in academic and clinical environments to enable positive student interactions. 相似文献

BackgroundRural populations face many health disadvantages compared to urban areas. There is a critical need to better understand the current lung cancer screening landscape in these communities to identify targeted areas to improve the impact of this proven tool.MethodsData from the County Health Rankings of New Hampshire and Vermont was reviewed for population density, distribution of adult smokers, and level of education compared to the distribution of Lung Cancer Screening Facilities throughout these two states.ResultsScreening programs in southern counties of Vermont with lower levels of education have decreased access. In New Hampshire, there are no programs within 30 miles of the areas with the largest distribution of smokers, and decreased access in some areas with the lowest levels of education.ConclusionsImproving equitable access to high-quality screening services in rural regions and the creation of targeted interventions to address decreased access in areas of high tobacco use and low education is vital to decreasing the incidence of latestage presentations of lung cancer within these populations. 相似文献
