目的 评价手卫生健康教育对重症监护病房（ICU）患者家属手卫生依从性的影响。 方法 选取2012年3月－5月ICU患者家属558人，对其进行手卫生健康教育。将健康教育前的1个月定义为第1阶段(基线调查阶段），健康教育当月定义为第2阶段，健康教育结束后的第1个月定义为第3阶段。对ICU患者家属开展手卫生健康教育，第1和第3阶段均采用张贴展板和宣教图片，床旁准备速干手消毒液；第2阶段在此基础上，每周示范六步洗手法3次，由责任护士督促并指导家属使用速干手消毒液进行手卫生。观察3个阶段患者家属手卫生依从性变化情况。 结果 在对“接触患者前”、“接触患者后”和“接触患者周围环境后”3个手卫生时机的依从率比较中，第2阶段明显高于第1阶段（P＜0.01）；第3阶段较第2阶段有明显下降（P＜0.01）；在3个阶段中，使用速干手消毒液进行手卫生的人数均高于使用洗手液的人数。 结论 手卫生健康教育普及了手卫生相关知识，提高了ICU患者家属对手卫生的依从性。
Objective To know about the baseline and quality of clinical prophylaxis and treatment study on communicable diseases in China, by identifying and assessing the clinical studies published in Chinese Journal of Infectious Diseases for 18 years. Method Handsearching page by page to identify and register the clinical studies from the journal, the definition of randomized controlled trial (RCT) and controlled clinical trial (CCT) strictly according to the Cochrane Collaboration Handbook (1997). Results There were totally 214 clinical studies during the 18 years, including 67 RCTs, 67 CCTs and 80 Non-CCTs. The average sample size of the RCTs was 103.0±70.2 (range from 17 to 296). Counted by every 5 years period (3 years period from 1998 to 2000), the proportion of RCTs in clinical studies was increasing steadily. The proportion were 22.9% from 1983 to 1987 (11/48), 29.2% from 1988 to 1992 (14/48), 41.9% from 1993 to 1997 (26/62), 28.6% from 1998 to 2000 (16/56) respectively. The main diseases studied in 214 clinical studies include: virus hepatitis (65 studies), hemorrhagic fever with renal syndrome (19 studies), typhoid fever (11 studies), bacterial infection (13 studies), bacillary dysentery (5 studies), epidemic encephalitis B (3 studies) and parasitosis (9 studies). Conclusion RCT study design should be applied as much as possible. The quality of clinical studies on communicable diseases in China remains to be improved. Multi-center and large-scale collaborative study is worthy to advocate.
ObjectiveTo investigate the diagnostic value and the best criteria of multiplanar reconstruction (MPR) of spiral CT in recurrent laryngeal nerve lymph node metastasis.MethodsWe performed multiplanar reconstruction of the spiral CT data of 138 esophageal carcinoma patients admitted to our hospital between December 2016 and June 2019, including 113 males and 25 females with an average age of 47-85 (63.03±15.58) years. The short and long diameters of recurrent laryngeal nerve lymph nodes were measured respectively, and then ratio of short to long diameter was calculated. The three parameters were contrasted with the pathological results and the receiver operating characteristic (ROC) curves for the parameters were drawn.ResultsOf the 138 patients, 291 left recurrent laryngeal nerve lymph nodes were dissected with an average number of 0-14 (2.11±0.41) per patient and the metastasis rate was 16.70%; while 436 right ones were dissected with the average number of 0-17 (3.16±0.45) per patient and the metastasis rate was 21.00%. The total metastasis rate was 29.70%. In the diagnosis of lymph node metastasis, the areas under ROC curve for short and long diameters as well as the ratio of short to long diameter of left recurrent laryngeal nerve lymph nodes were 0.808, 0.779, 0.621, respectively, while those for the right ones were 0.865, 0.807, 0.637, respectively.ConclusionThe metastasis rate of recurrent laryngeal nerve lymph nodes is high and the short diameter has a higher diagnostic value for recurrent laryngeal nerve lymph node metastasis.
Objective To understand the sexual behavior statu of married migrant workers in Chongqing, so as to provide the government with foundation for formulating related social strategies. Methods A multi-stage stratified cluster random sampling method was applied to select respondents, and the face-to-face interview was performed to investigate by trained investigators. The date was analyzed by using SAS9.0 software. Results A total of 377 married migrant workers were investigated. Among them, 226 (59.95%) lived with their spouses, of whom 13.72% had extramarital sexual behaviors, with 48.39% commercial sexual behaviors; the other 151 (40.05%) didn’t live with their spouses, of whom 49.25% had no normal sexual life for at least three months and 28.48% had extramarital sexual behaviors, with 60.47% commercial sexual behaviors. 66.41% of male migrant workers and 46.28% of female migrant workers had sexual depression, and different genders between the migrant workers were statistically significant (Plt;0.05). Conclusion There is sexual depression among married migrant workers. The related measures should be taken according to the status of their sexual behaviors, so as to improve their status of sexual depression.
The QUADAS-2, QUIPS, and PROBAST tools are not specific for prognostic accuracy studies and the use of these tools to assess the risk of bias in prognostic accuracy studies is prone to bias. Therefore, QUAPAS, a risk of bias assessment tool for prognostic accuracy studies, has recently been developed. The tool combines QUADAS-2, QUIPS, and PROBAST, and consists of 5 domains, 18 signaling questions, 5 risk of bias questions, and 4 applicability questions. This paper will introduce the content and usage of QUAPAS to provide inspiration and references for domestic researchers.
The use of clinical predictive modeling to guide clinical decision-making and thus provide accurate diagnosis and treatment services for patients has become a clinical consensus and trend. However, the models available for clinical use are more limited due to unstandardised research methods and poor quality of evidence. This paper introduces the development process of clinical prediction models from six aspects, data collection, model development, performance evaluation, model validation, model presentation and model updating, as well as the clinical prediction model research report statement and risk of bias assessment tools in order to provide methodological references for domestic researchers.
