Using National Data Sets on CD-ROM to Teach Nursing Research

Purpose : To explore the use of national data sets on CD-ROM for teaching graduate nursing research.
Significance: Secondary data analysis of national health data sets is economical and provides a useful experience for students learning research.
Scope: The advantages and disadvantages of using national health data sets on CD-ROM are described. Students in three majors in nursing worked in groups to address research questions that could be answered using variables in the National Health Interview Survey. Several computer laboratory sessions were held to teach students how to extract the data and apply SPSS to analyze data.
Findings: The pilot program was a success, but not without problems. Ten steps to ensure better attainment of objectives were formulated.
Conclusions: National data sets on CD-ROM are an inexpensive, rich data source that allow flexibility for students and faculty. Secondary data analysis using national health data sets is an underused approach in nursing. Graduate students can have a significant research experience while curbing the costs-to organizations and themselves-associated with primary data collection.     

The identification of high risk asthmatic children using the emergency department asthma visit count

A subset of asthma patients accounts for a disproportionate amount of health care resources through repeat visits. A retrospective analysis of emergency department (ED) billing and admission databases was performed to assess the value of the asthma visit count as an indicator of future health care utilization. The asthma visit count was found to have a direct and linear relationship with both future ED visits and future inpatient admission for asthma. Children with 2 visits in 1997 had a substantial (26.9%) risk of returning in the 1998 study period, and a 6.6% risk of admission. Children who visited the ED 3 or more times in 1997 for asthma had a risk of repeat visit of more than 52%, and more than 12% of this highest risk group were admitted to the hospital at least once during the 1998 study period. Once an annual asthma visit count of 3 or more is achieved, there can be little controversy with the “high utilizer” label. The substantial increase in the visit and admission risk warrants consideration of the asthma visit count as an easily obtainable, objective marker to identify high-risk children for both study and clinical purposes. Further research is needed.     

Computer-Mediated, Self-Directed Computer Training and Skill Assessment for Individuals with Mental Retardation

By and large, people with mental retardation have not experienced the educational benefits, productivity gains, and personal enrichment that can result from the use of personal computers. Computer use has been restricted for individuals with mental retardation for several reasons, including the lack of opportunities to learn how to use computer hardware and software. One potential solution to this problem is to use the computer itself, through computer-delivered instruction, to teach basic computer skills. However, most currently available instructional software has been developed either for adults with full cognitive capacities or specifically for children. This study examined use of a multimedia software program designed for self-directed computer training and skill assessment for adults with mental retardation. Study participants with mental retardation used the software in a self-directed manner to increase their independence, speed, and accuracy in learning basic computer use skills.     

肝硬化的数量化诊断及其影像分型

通过对肝硬化进行量化研究,为临床影像诊断提供依据.选择正常人肝脏横断位CT图片作为对照组,选择肝硬化代偿期组、失代偿期组、肝癌组作为疾病组进行对比研究.利用人体常用解剖轴线作为肝脏测量的基准线.肝脏左叶冠状径(L1)的变化最具有临床意义,肝叶比例不仅存在于肝叶之间也存在于肝叶之内.肝脏各叶测量值对于早期肝硬化的诊断具有重要的意义.     

Video‐assisted segmental resection of an intrapulmonary bronchogenic cyst mimicking a middle mediastinal cystic tumor

We report a case of an intrapulmonary bronchogenic cyst that radiologically mimicked a cystic tumor of the middle mediastinum. During video‐assisted thoracoscopic surgery, the lesion was confirmed to be in the lung parenchyma rather than in the mediastinum. A video‐assisted thoracoscopic anterior basal segmentectomy was eventually performed, and an intrapulmonary bronchogenic cyst was the diagnosis based on histology.
