PurposeSurface-guided radiotherapy is useful for the pre-positioning and monitoring of radiotherapy. The purpose of this study was to investigate the impact of surface guidance on the repeatability of patient localization and to estimate the specific point at which high positional errors occur.Materials and methodsTen patients without the VOXELAN system (non-VXLN group) and 10 patients with the VOXELAN as the pre-positioning procedure (VXLN group) were included in this analysis. Twelve regions of interest (ROI) were defined in all the patients to verify any misalignment during radiotherapy. Thirteen ROIs were defined on the isocenter.ResultsCompared with the non-VXLN group, the translational positional errors of the VXLN group were the same for all the ROIs. The mean translational positional errors of the VXLN group in the longitudinal direction were approximately 0.1 mm, and the standard deviation was the largest among the three directions in all the ROIs. The magnitude of the standard deviation in the non-VXLN group varied independently of the ROI and direction. The standard deviations of the VXLN group in the longitudinal direction were large in all the ROIs, while the standard deviations in the vertical and lateral directions were small.ConclusionPre-positioning with a surface guidance system reduced the body twist and rotation, which could not be corrected by image-guided radiotherapy alone. Since the VOXELAN can detect positioning errors quickly and without additional radiation exposure to the patient, it can be used as a tool for pre-positioning in radiotherapy. 相似文献

目前新型冠状病毒感染疫情在全国蔓延,疫情防控成为医院工作的重点。口腔科门诊患者人流量大、口腔疾患多、口腔内病菌种类复杂、诊疗过程中患者无法戴口罩、医务人员的手和器械需要接触患者的唾液、血液、病菌等,特别是在相对封闭的环境中长时间暴露于高浓度气溶胶情况下存在经气溶胶传播的可能。本院口腔科门诊通过开诊前准备、就诊期间应急管理、消毒隔离管理等方面细化防疫措施,成果显著,有效保障医患安全。 相似文献

Brochures are a useful supplement to patient education. There is increasing evidence that they are an effective medium to support patient satisfaction, adherence, and empowerment. This study aims to produce reliable data on how much patients with venous leg ulcer (VLU) may profit from a brochure that focuses on VLU and on measures and aims of the related compression therapy. The evaluation took part from October 2018 until March 2019 and included 136 patients with VLU and related compression therapy. They were randomly sorted into a case group and a control group of 68 patients each. The case group received a brochure about venous disease and compression therapy and filled in a questionnaire after reading. The questions ranged from basic knowledge about VLU and compression therapy to aspects of self‐care. The control group answered the same questions without previous reading of the brochure. The results show that in almost every aspect, the patients in the case group were better informed about their diseases, the compression therapy, and how they may support the measures adequately. This study suggests that patients with VLU may profit from a brochure that explains their disease and the related compression therapy. Better knowledge and understanding may strengthen their empowerment and adherence. 相似文献

Research campaigns in the UK National Health Service: patient recruitment and questions of valuation
Matthias Wienroth Caroline Pearce Christopher McKevitt 《Sociology of health & illness》2019,41(7):1444-1461
The National Institute for Health Research (NIHR) aims to improve national ‘health and wealth' by providing infrastructural support to enable clinical research in National Health Service settings in England and Wales. Cognisant of the consequences of studies' failure to achieve required numbers of participants, it also actively campaigns to promote patient awareness of research, and willingness to participate in trials. In this paper, we analyse recent NIHR campaigns and policies designed to encourage patients to participate in clinical research to interrogate how they are implicated in the national bioeconomy. In doing so we expand the notion of ‘clinical labour' to include the work of patient recruitment and highlight an emergent obligation on patients to contribute to research processes. Whereas once patient knowledge and experience may have been devalued, here we draw on the concept of ‘assetisation' (Birch 2012) to explore the emergent relationship between healthcare system and patient as research participant. We consider how patients' contribution goes beyond the provision of standardised objects of valuation so that patients themselves may be perceived as assets to, not only recipients of, the national healthcare system. 相似文献

Schizophrenia is a chronic mental pathology with polymorphous symptoms that have an invalidating impact on an emotional, interpersonal, behavioural and social level. In certain cases this pathology can increase the risk of self-harm or harm to others, making it necessary to put protocoles in place for specifically-adapted treatment, put forward notably by care units that deal with dangerous patients. The patient's therapeutic education, orientated towards acquiring knowledge about the illness and skills for dealing with it in day-to-day life, is now a recognised practice, having proven its effectiveness in the treatment of chronic psychiatric patients. There is significant interest in this method for treating dangerous mental patients. In this interview, the psychologist Diane Brulin-Solignac shares her knowledge and experience of this therapeutic practice. 相似文献
