Reliability and validity of the Japanese version of the Biological Rhythms Interview of assessment in neuropsychiatry-self report for delayed sleep-wake phase disorder

ObjectiveThe Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) might be applicable for assessing delayed sleep-wake phase disorder (DSWPD). We aimed to investigate the reliability and validity of the Japanese version of the BRIAN self-report (J-BRIAN-SR) in DSWPD patients and determine a cutoff score to identify the presence of the disorder.MethodsWe enrolled 60 newly diagnosed DSWPD outpatients and 64 age-matched healthy controls. We used Cronbach's alpha for internal reliability to evaluate J-BRIAN-SR. We confirmed the reliability of the A test and re-test using Pearson's correlation coefficient in the controls. We used confirmatory factor analysis to evaluate the factor structure of J-BRIAN-SR and referenced the Morningness-Eveningness Questionnaire (MEQ) to check concurrent validity. We analyzed the receiver operating characteristic curve (ROC) to determine the J-BRIAN-SR cutoff point for the presence of DSWPD.ResultsThe 18-component scores of the J-BRIAN-SR had an overall reliability coefficient (Cronbach's alpha) of 0.82. We confirmed a high test-retest reliability using an intraclass correlation coefficient (r = 0.84). The correlation between J-BRIAN-SR and MEQ was 0.38 (p = 0.003). The J-BRIAN-SR that we extracted by exploratory factor analysis consisted of three factors. A score of 40 points provided a sensitivity of 80.0% and a specificity of 75.6% for the positivity of DSWPD.ConclusionsThe results of the present study revealed that J-BRIAN-SR is a valid and reliable instrument for screening and evaluating the severity of DSWPD. Our findings will be useful to physicians and patients in Japan and those in clinical settings.     

Translation and validation of the clinical learning environment,supervision and nurse teacher scale (CLES + T) in Croatian language

Clinical practice is essential to nursing education as it provides experience with patients and work environments that prepare students for future work as nurses. The aim of this study was to translate the “Clinical Learning Environment, Supervision and Nurse Teacher” questionnaire in Croatian language and test its validity and reliability in practice. The study was performed at the Faculty of medicine, Josip Juraj Strossmayer University of Osijek, Croatia in April 2014. The translated questionnaire was submitted to 136 nursing students: 20 males and 116 females. Our results reflected a slightly different factor structure, consisting of four factors. All translated items of the original constructs “Supervisory relationship”, “Role of nurse teacher” and “Leadership style of the ward manager” loaded on factor 1. Items of “Pedagogical atmosphere on the ward” are distributed on two factors (3 and 4). The items of “Premises of nursing on the ward” loaded on factor 2. Three items were identified as problematic and iteratively removed from the analysis. The translated version of the aforementioned questionnaire has properties suitable for the evaluation of clinical practice for nursing students within a Croatian context and reflects the specifics of the nursing clinical education in this country.     

政策工具视角下国内护理卫生政策的文本分析

目的 研究1978年—2020年护理卫生政策中政策工具使用情况,探讨现有政策工具的分布情况及框架结构,为后续政策的制定及落实提供参考。方法 基于Rothwell&Zegveld构建的政策工具分析框架,采用内容分析法,构建X维度（基本政策工具）及Y维度（政策发展阶段）的二维分析框架,对现有护理卫生政策文本进行编码整理和量化分析。结果 最终纳入24篇政策文件,共整理378条政策分析条目。X维度中,供给型、需求型、环境型政策工具所占比例分别为24.60%、14.02%、61.38%。Y维度中,萌芽探索期、补充完善期、成熟提升期政策工具占比分别为23.02%、31.75%、45.24%。结论 目前国内护理卫生政策工具总体使用不协调,供给型政策工具较关注人才培养,科技研究和信息化建设有待增加;需求型政策工具应用较少,缺乏有效拉动作用;环境型政策工具使用过于频繁,内部工具比例有待调整。建议可进一步把握护理卫生政策演化的规律性,提升政策实施的实效性,强化政策组合的整体性。     

计量控制机制对预防误诊误治的作用

误诊误治现象是发生于医疗服务过程中的一种客观存在.随着临床诊断、治疗方法及检查手段的工程技术化,医学仪器的计量是否准确,将直接影响临床诊断的准确性及治疗的有效性.现代的临床诊断（包括物理诊断、生化诊断、影像诊断）主要是靠医疗仪器来实现的,文章引入医学计量控制机制,说明通过对医学仪器的测量控制、计量监督和计量评审的方法,检查或检验医疗器械的技术参数是否满足相应的标准、规程和技术规范的要求,对医疗仪器的可用性进行确认,从而最大限度的降低由于医疗服务工程技术化导致误诊误治的可能性.     

自制枪状钛夹钳在经蝶手术中的应用

目的 研制一种经蝶手术时能有效处理海绵间窦出血和硬脑膜反折处脑脊液漏的手术器械,并评估其在临床实践中的应用效果和安全性.方法 采用钛合金材料,制成工作长度为21cm、前段呈直角的枪状钛夹钳.将此枪状钛夹钳应用在34例垂体腺瘤经蝶手术中,并对手术患者进行24个月随访,术后3 ～18个月做X线及MRI检查,示钛夹位置良好且无明显伪影发生.结果 自制枪状钛夹钳术中使用方便有效,34例手术灾闭海绵间窦出血或硬脑膜反折处脑脊液漏获得成功,无迟发性出血或脑脊液漏再次发生,随访结果亦无钛夹相关性并发症发生.结论 自制枪状钛夹钳在经蝶手术中能有效、安全、快速处理海绵间窦的出血和硬脑膜反折处的脑脊液漏.     

腹腔镜手术器械灭菌方法的探讨
