《Radiography》2022,28(1):187-192
IntroductionDiagnostic Radiography plays a major role in the diagnosis and management of patients with Covid-19. This has seen an increase in the demand for imaging services, putting pressure on the workforce. Diagnostic radiographers, as with many other healthcare professions, have been on the frontline, dealing with an unprecedented situation. This research aimed to explore the experience of diagnostic radiographers working clinically during the Covid-19 pandemic.MethodsInfluenced by interpretative phenomenology, this study explored the experiences of diagnostic radiographers using virtual focus group interviews as a method of data collection.ResultsData were analysed independently by four researchers and five themes emerged from the data. Adapting to new ways of working, feelings and emotions, support mechanisms, self-protection and resilience, and professional recognition.ConclusionThe adaptability of radiographers came across strongly in this study. Anxieties attributed to the provision of personal protective equipment (PPE), fear of contracting the virus and spreading it to family members were evident. The resilience of radiographers working throughout this pandemic came across strongly throughout this study. A significant factor for coping has been peer support from colleagues within the workplace. The study highlighted the lack of understanding of the role of the radiographer and how the profession is perceived by other health care professionals.Implications for practiceThis study highlights the importance of interprofessional working and that further work is required in the promotion of the profession.  相似文献

Occupational injuries represent an enormous economic impact for victims, respective families, involved institutions and all the community due to professional outcomes. Thus, it is of the utmost importance that medico-legal personal injury assessment and the posterior follow-up of these victims, may allow their concrete damage repair, considering the victims' needs fulfilment and professional reintegration, whenever possible. The main objective of this study is to reflect on the role that legal medicine can play in promoting the professional reintegration of victims of major occupational accidents through the analysis of occupational injuries cases considering the medico-legal examinations performed. A retrospective study was conducted using medico-legal major occupational injuries cases (Partial Permanent Disability ≥40%). Data were collected from two medico-legal assessment moments: (a) personal injury assessment homologated by a labour court 4.8 years on average after occupational injury; (b) medico-legal follow-up for needs and/or Partial Permanent Disability adjustments performed 18.9 years on average after occupational injury. The final sample includes 103 cases. The results showed that in major occupational accidents, permanent long-term outcomes were principally associated with neurological (62.1%) and orthopaedic (52.4%) sequelae. Permanent professional damage parameters assigned by the labour court included Partial Permanent Disability (23.3%), Permanent Absolute Disability for Regular Work (41.7%) and Permanent Absolute Disability for Any Work (35%). Three-dimensional methodology is helpful in predicting Partial Permanent Disability and Permanent Absolute Disability for Any Work. However, three-dimensional methodology did not reveal correlations with Permanent Absolute Disability for Regular Work, and currently 65% of the victims who were considered able to work by the labour court are not professionally active. Thus, these major cases deserve a more detailed medico-legal approach based on concrete information about the professional reality of each victim, especially cases with an eventual Permanent Absolute Disability for Regular Work. Medico-legal Injury Assessment must be based on concrete aspects of the victim's professional reality and not only on permanent disability tables. This calls for an articulation between all institutions working with the victim of occupational injuries and legal medicine to promote recovery and the necessary measures to assure professional rehabilitation.  相似文献

目的评估不同年资以及是否有专业背景的超声医师孕期宫颈超声检查的报告质量。 方法从超声医学影像工作站导出并选择2019年1月1日至12月31日北京协和医院经会阴与经阴道超声孕期检查宫颈的超声报告624份。检查医师分为第1年住院医师(G1组)、第2~3年住院医师(G2组)和专业医师(G3组)。参考加拿大妇产科医师协会母胎医学专业委员会指南,由2位工作经验>10年的超声医师对上述图文报告进行评估,分为符合、不符合,通过χ2检验或Fisher精确检验进行组间比较。 结果满足入选标准与排除标准的624份宫颈超声检查报告中,经会阴超声检查507份(81.2%,507/624),经阴道超声检查117份(18.8%,117/624)。G1组、G2组、G3组检查医师人数分别为:16名、33名、13名。经会阴超声检查,G1组、G2组、G3组的总报告数分别为90份、326份、91份,其符合率分别为74.4%(67/90)、85.9%(280/326)、86.8%(79/91),G1与G2组、G1与G3组比较,差异有统计学意义(χ2=6.678,P=0.010;χ2=4.438,P=0.035),G2与G3组比较,差异无统计学意义(P>0.05)。经阴道超声检查,G1+G2组、G3组的总报告数分别为44份、73份,其符合率分别为75.0%(33/44)、91.8%(67/73),2组比较差异有统计学意义(χ2=6.225,P=0.013)。相同年资医师经会阴与经阴道宫颈超声检查的符合率之间比较,差异无统计学意义(P>0.05)。 结论经阴道超声宫颈检查专业组医师符合率较高,经会阴超声检查符合率随着年资增高而增高。病例积累和标准化专业培训是提高孕期宫颈超声检查的有效途径。  相似文献

The study explored adult gerontology acute care nurse practitioner (AGACNP) student’s self-perception of confidence and competence in essential domains of nurse practitioner (NP) skills. A preclinical hospital immersion experience was developed to improve transition to the ACACNP role. AGACNP students participated in once-weekly sessions for 3 consecutive weeks, with 14 students completing the experience over a 3-year period. Data showed a 28.7% improvement in student’s self-perception of confidence and competence, with statistically significant improvement in clinical decision-making skills and NP role. AGACNP students requested additional days and appreciated direct faculty feedback, while faculty efficiently supported AGACNP role transition.  相似文献

目的 了解新护士工作准备度及情绪劳动水平,并分析两者之间的关系,为新护士顺利进入工作角色提供参考。 方法 采用一般资料调查表、中文版毕业护士工作准备度量表及情绪劳动量表,对新疆维吾尔自治区8所三甲医院工作1年内911名护士进行调查。 结果 新护士工作准备度总分(269.54±48.70)分,情绪劳动总分(46.85±11.91)分,两者呈负相关(r=-0.235,P<0.05);控制一般资料后,情绪劳动量表的表层扮演、深层扮演维度可解释新护士工作准备度35.5%的变异(均P<0.05)。 结论 新护士工作准备度及情绪劳动均处于中等水平,表层扮演负向预测工作准备度,深层扮演正向预测工作准备度。管理者需重视新护士情绪劳动评估,重点关注倾向于表层扮演的新护士,以提高其工作准备度。  相似文献
