Implementation of an integrated glucose POCT system

In response to a change of the Belgian National Directives whereby hospital laboratories became responsible for all point-of-care testing (POCT) performed within hospital walls a standardized and automated POC glucose-testing system was implemented in our hospital. The system consists of 50 AccuCheck Inform instruments (Roche Diagnostics, Vilvoorde, Belgium), 50 docking stations, a DataCare Server, and connections to the medical laboratory information system (MOLIS, Sysmex, Barchon, Belgium) and to the hospital information system. Implementation involved many parties and extensive preparation and communication. Key issues were bar-coded patient and user identification, training, and responsibilities. One year after the hospital wide implementation of this system the quality of POC glucose testing has significantly increased, thereby improving patient safety. This study describes a stepwise change over involving the medical laboratory and with a focus on hands-on quality.Presented at the ninth conference on Quality in the Spotlight, 18–19 March 2004, Antwerp, Belgium.

Rugged distal tips for CO2 laser medicine

Low-loss and rugged distal tips for CO₂ laser have been proposed and fabricated based on a commercially available stainless steel (St) pipe. A method of smoothening the inner surface of the St pipe with a rough inner surface is put forward. Fabrication parameters, transmission properties, and mechanical strength of the cyclic olefin polymer-coated silver hollow St distal tip are experimentally discussed.     

药用植物化学分类法与红外指纹图谱的相关性研究

本文首次采用傅里叶变换红外光谱法(FTIR)对五加科、桔梗科、木兰科、樟科、豆科、蕨类等科目中的典型药用植物进行了系统研究,比较了各科内植物的异同,并且讨论了相同植物不同药用部位、不同采药时间对其红外谱图的影响。结合药典中关于药物主体有效成分的记载,分析了各药用植物谱图中主要成分的特征基团,对主要吸收峰进行了指认。在传统形态比较分类方法的基础上,FTIR可以成为一种快速、可靠、客观、有效的化学分类学的补充方法。

中晚期高危妊娠引产32例分析及经验总结

目的：分析中晚期妊娠合并症引产病例的特征，适当引产方式的选择。总结引产处理成功的经验。方法：总结32例中晚期妊娠合并内外科疾病选择引产病例，分析各病种分布以及引产方式、引产并发症。结果：32例病例中肝肾疾病占31％，选择利凡诺引产15例，水囊引产12例，药物引产4例。均无内外科并发症发生。结论：做好有妊娠合并症的中晚期引产的术前术中准备工作，选择合适的引产方式是引产成功安全的关键。     

南药巴戟天中十二种无机元素与药效关系的进一步研究

在初步研究的基础上，进一步研究了不同产地巴戟天的无机元素含量差异，通过对比各元素含量、相关系数及TE图谱，说明地道药材与非地道药材的巴戟天，其特征元素的含量存在非常明显的差异，要使大面积扩种的药材提高药效，建议根据当地土壤含Mn、Fe、Cr、Co、Ni的含量，以旋微量元素肥料的方法来补充这些元素在土壤中的不足。但在微量元素肥料配方中，应注意巴戟天吸收土壤中的元素时的协同作用和拮抗作用。     

Application of similarity aggregation techniques to a population of paraplegic patients

We studied a population of paraplegic patients in order to give prominence to a possible relationship between the topography of their spinal lesion and the occurrence of special articular diseases (P.O.A.). According to the motor and sensory state of their spinal cord, we first tried to obtain a classification of these lesions (the usual one schematically separates ‘flaccid’ and ‘rigid’ paraplegics). We mainly put the emphasis on this clustering step of the study:

Is it safe to have a laboratory test?

A recent US Institute of Medicine report indicated that up to 98,000 deaths and more than 1 million injuries occur each year in the United States due to medical errors. These include diagnostic errors, such as an error or delay in diagnosis, failure to employ indicated tests and the use of outmoded tests. Laboratory tests provide up to 80% of the information used by physicians to make important medical decisions, therefore it is important to determine how often laboratory testing mistakes occur, whether they cause patient harm, where they are most likely to occur in the testing process, and how to prevent them from occurring. A review of the literature and a US Quality Institute Conference in 2003 indicates that errors in laboratory medicine occur most often in the pre-analytical and post-analytical steps in the testing process, but most of the quality improvement efforts focus on improving the analytical process. Measures must be developed and employed to reduce the potential for mistakes in laboratory medicine, including better indicators for the quality of laboratory service. Users of laboratory services must be linked with the laboratorys information system to assist them with decisions about test ordering, patient preparation, and test interpretation. Quality assessment efforts need to be expanded beyond external quality assessment programs to encompass the detection of non-analytical mistakes and improving communication between the users of and providers of laboratory services. The actual number of mistakes in laboratory testing is not fully recognized, because no widespread process is in place to either determine how often mistakes occur or to systematically eliminate sources of error. We also tend to focus on mistakes that result in adverse events, not the near misses that cause no observable harm. The users of laboratory services must become aware of where testing mistakes can occur and actively participate in designing processes to prevent mistakes. Most importantly, healthcare institutions need to adopt a culture of safety, which is implemented at all levels of the organization. This includes establishing closer links between providers of laboratory services and others in the healthcare delivery system. This was the theme of a 2003 Quality Institute Conference aimed at making the laboratory a key partner in patient safety. Plans to create a permanent public–private partnership, called the Institute for Quality in Laboratory Medicine, whose mission is to promote improvements in the use of laboratory tests and laboratory services are underway.Presented at the 9th Conference on Quality in the Spotlight, 18–19 March 2004, Antwerp, Belgium.
