Antifungal susceptibility testing practices in mycology laboratories in France, 2018

A survey of mycology laboratories for antifungal susceptibility testing (AFST) was undertaken in France in 2018, to better understand the difference in practices between the participating centers and to identify the difficulties they may encounter as well as eventual gaps with published standards and guidelines. The survey captured information from 45 mycology laboratories in France on how they perform AFST (number of strains tested, preferred method, technical and quality aspects, interpretation of the MIC values, reading and interpretation difficulties). Results indicated that 86% of respondents used Etest as AFST method, with a combination of one to seven antifungal agents tested. Most of the participating laboratories used similar technical parameters to perform their AFST method and a large majority used, as recommended, internal and external quality assessments. Almost all the participating mycology laboratories (98%) reported difficulties to interpret the MIC values, especially when no clinical breakpoints are available. The survey highlighted that the current AFST practices in France need homogenization, particularly for MIC reading and interpretation.     

Enhancing laboratory report contents to improve outpatient management of test results

In today''s environment, providers are extremely time-constrained. Assembling relevant contextual data to make decisions on laboratory results can take a significant amount of time from the day. The Regenstrief Institute has created a system which leverages data within Indiana Health Information Exchange''s (IHIE''s) repository, the Indiana Network for Patient Care (INPC), to provide well-organized and contextual information on returning laboratory results to outpatient providers. The system described here uses data extracted from INPC to add historical test results, medication-dispensing events, visit information, and clinical reminders to traditional laboratory result reports. These “Enhanced Laboratory Reports” (ELRs) are seamlessly delivered to outpatient practices connected through IHIE via the DOCS4DOCS clinical messaging service. All practices, including those without electronic medical record systems, can receive ELRs. In this paper, the design and implementation issues in creating this system are discussed, and generally favorable preliminary results of attitudes by providers towards ELRs are reported.

An inexpensive ex-vivo porcine laparoscopic Nissen fundoplication training model.

BACKGROUND: We recently implemented the use of an ex-vivo porcine model to teach residents the fundamentals of performing a laparoscopic Nissen fundoplication. METHODS: Residents were trained using intact porcine esophagus, stomach, and spleen placed in a standard video-trainer. They were later asked to complete a survey containing a course evaluation. RESULTS: Sixteen residents (R1-R4) completed the survey. They agreed that (1) the exercise was a valuable use of their limited time, (2) repeating the exercise will be of additional benefit, (3) it will improve their ability to perform or assist in an actual case in the OR, and (4) the surgical principles learned using the model will transfer to other laparoscopic cases. Significant subjective improvements were reported in resident comfort level in assisting in or performing a laparoscopic Nissen fundoplication. CONCLUSIONS: The use of an inexpensive ex-vivo porcine training model increases resident comfort level in performing a Nissen fundoplication in the operating room.     

通过三年资料实证医院检验科常规项目全成本

目的弄清医院常规检验项目的实际成本,为医院及卫生主管部门进行科学管理和政府物价部门制订科学合理的收费价格体系提供科学依据。方法对某二级甲等医院检验科3年中所开展的全部7大类16个项目组169个检验项目的成本按耗材、设备折旧、劳务费、房屋折旧、业务费与后勤管理费共5大类进行实证分析。结果该科的成本构成比是:耗材成本34.1%、设备折旧24.3%、劳务费30.0%、房屋折旧4.0%、业务费与后勤管理费7.6%;检验项目的每项次平均成本为7.17元;成本最低的两类检验项目是生化及定性免疫,其项次成本分别为3.18元和4.25元;最高的则为微生物和血库,项次成本分别为48.63元和35.21元;项次成本过百元的有7项,多为输血项目;5至10倍于平均成本的28项,2至5倍于全科平均成本的22项,其余112项介于全科平均成本上下。结论实证研究是准确掌握检验项目成本的有效方法。

加入世界贸易组织后我国实验动物行业社会化、商品化趋势

加入世界贸易组织(WTO）是我国经济融入世界经济，参与全球化竞争的必由之路。我国实验动物商品化程度很低，产权不明晰，管理理念陈旧落后，提供的实验动物服务质量、数量、效率都很低。难以支撑现代科学技术运转需求，如不进行改革，在渡过入世五年的调整期后，中国的实验动物服务体系难以与国际同行抗衡。本就改变现阶段我国实验动物行业不适应市场经济和科研条件的状态，主动寻找产生这种现状的根源与对策，充分利用和发掘现有资源，把实验动物管理与服务职能分离，探求实验动物行业商品化经营的策略和应对的措施。
