ObjectiveTo objectively assess the quality of “crisis communication” media, during the COVID-19 pandemic, in the three Greater Maghreb countries (Tunisia, Algeria, Morocco).MethodsA compliance audit for press releases and epidemiological bulletins was analyzed against a quality benchmark, which had been specifically designed by the authors. This framework, made up of five dimensions and 50 items, graded (0/1), was applied by two researchers in preventive medicine. Multiplying the scores by a coefficient of two resulted in a partial score of 20 points for each dimension and a total score of 100 points for the checklist taken as a whole. The quality of the communication media was considered to be good when exceeding the thresholds of 15/20 for the different dimensions and 75/100 for the entire grid.ResultsA total of 141 information media were included in this audit (Tunisia: 60; Algeria: 60; Morocco: 21). The overall median quality score for these media was only 56/100 (IIQ: [46–58]), without major variability between countries. The most appreciated dimension was “maintaining the confidence of the population”, with an overall median score of 14/20 (12/20 for epidemiological bulletins and 16/20 for press releases). The most poorly rated dimension was “strengthening community participation”, with a median score of only 4/20 (6/20 for epidemiological bulletins and 4/20 for press releases).ConclusionThe quality of the Maghreb crisis communication media during COVID-19 was insufficient in most of its dimensions and items, particularly from a psychosocial standpoint. Reinforcement of the capacities of communication officers to develop information material and supports during health crises is indispensable and should be considered as an urgent matter. 相似文献

Community health and social care practitioners play an increasingly important role in the health promotion agenda, but lack confidence in having effective health behaviour change (HBC) conversations with members of the public. This study reports the development and evaluation of a training intervention based on health psychology to improve health and social care practitioner self-rated confidence, competence and intention to use five behaviour change techniques (BCTs) in their HBC conversations. A 2-day behavioural science interprofessional skills training course plus online learning module was designed for health and social care staff across North East Scotland, teaching five evidence-based BCTs (e.g. Action Planning), plus person-centred communication skills. Participants rated confidence, competence and future intention to use the BCTs on likert scales (1–10) pre-course and post-course, and provided acceptability data. 177 participants aged 20–64 took part, qualitative and quantitative data suggested that the course had high acceptability. Paired samples t tests (n = 120 with complete data) showed significant improvements in confidence, competence and intention following the course, which remained significant with a conservative analysis (n = 174) assuming no change for missing data. Perceived competence in Action Planning increased most during the course (mean change 3.09). In conclusion, health psychology-based skills training can improve practitioner confidence, competence and intention to use evidence-based BCTs; further evaluation is needed to assess practice change. 相似文献

目的 了解职业技术类院校护理及助产专业医学生的心理对其医患沟通技能的影响作用,为职业技术类院校的医学生医患沟通技能提升提供指导。 方法 利用成熟的医学生医患沟通态度、技能以及心理学相关量表设计调查问卷,采用全部抽样的方式,对忻州职业技术学院护理专业学生进行调研,并最终获得264份有效问卷用于逐步进入法的多元线性回归分析。 结果 分析结果表明,医学生学习医患沟通技能的积极态度(r=0.39,P<0.001)、情绪疏泄能力(r=0.29,P<0.001)、观点采择意识(r=0.20,P<0.001)对其医患沟通技能水平的作用具有统计学意义。 结论 职业技术类院校在培养医学生的医患沟通技能时,应重点关注学生的积极学习态度、情绪疏泄能力和观点采择意识。 相似文献

PACS诊断工作站匹配小型DSA在介入治疗中的应用 总被引:2,自引:0,他引:2
目的 探讨PACS诊断工作站与小型DSA匹配在介入治疗中的应用价值。方法 PACS诊断工作站通过视频采集一转换方式采集岛津公司的WHA-50N/S小型DSA的PH-DSA方式获得的视频图像,使用DIGOM 3.0国际标准。对采用该系统检查治疗的67例图像资料进行分析,评价该工作站的使用效能。结果 将PACS诊断工作站与小型DSA相接后,将原来的PH-DSA视频图像转变为10~25帧/S的数字DSA图像,可上传输至PACS,达到资料共享。提高了图像后处理的功能。应用该系统获得的数字图像能够保持原设备的清晰程度,无明显失真,可以显示1~2mm的3~4级血管。结论采用小型DSA与PACS诊断工作站相匹配,可以为介入治疗的开展提供可靠的保障。 相似文献

CONTENT: This article discusses the rationale for, and the potential benefits and limitations of, computer-based interactive health communication (IHC) programs for health behavior counseling. We describe common barriers to health behavior counseling in medical settings and show how IHCs can address these issues. Following an overview of current and likely near-future IHCs, the potential impact of IHCs on the patient-provider relationship is considered. Results from evaluations of IHCs are summarized and important and unique issues in evaluating IHCs are discussed. We conclude with recommendations for clinical applications, including recommendations for consumers considering purchase or adoption of IHCs and recommendations for future research. 相似文献
