Evaluating the Health Information Technology Regional Extension Center in South Carolina

ObjectiveTo determine the impact of the South Carolina Regional Extension Center, Center for Information Technology Implementation Assistance (CITIA-SC), on physician practices engaged in the process of electronic medical record (EMR) adoption.Data sourcesData from a cross-sectional survey distributed in March 2011 to 1310 primary care practice groups throughout South Carolina was used to determine the degree of EMR adoption throughout the state (n=452 respondents; 34.5% response rate). Participation in CITIA-SC was determined by obtaining a list of practices from CITIA-SC.Study designA posttest-only design with nonequivalent groups was used to estimate the degree of EMR implementation, plans for and perceived barriers to implementation based on CITIA-SC participation.ResultsCITIA-SC practice sites faced similar barriers to EMR implementation as non-CITIA-SC participants, including initial or recurring cost of an EMR, low staff expertise with EMRs or computers, and productivity disruption. Additionally, CITIA-SC practice sites had fewer IT personnel on staff (p=0.0358) and were considering EMR implementation without a plan (p=0.0125). Despite these barriers, more practices participating in the CITIA-SC program were preparing to invest in an EMR system within one year when compared to nonparticipants (75.9% versus 28.3%, p<0.0001).ConclusionOur results indicated that the practice sites that participate in the REC had fewer IT resources and more perceived barriers to implementation. These results suggest that REC participant practice sites intend to implement an EMR, but recognize the need for technical assistance in the preparation and implementation of an EMR system.     

Ultrasound quality assurance and equipment governance

A case is presented to show the importance of good governance of ultrasound medical imaging equipment. Issues relating to the large numbers and diverse range of users and equipment are identified. Based on experience gained over 25 years, supporting upwards of 1000 systems, discussions consider why and how the testing of ultrasound systems should be approached by both the medical physics expert and end user. The management of the process is presented in the context of professional guidance and monitoring organisations’ standards are considered to give a suggested best practice.

慢性乙肝中医证型的机体免疫反应状况分析

目的：通过分析慢性乙肝5种中医证型患者外周血浆蛋白质的差异表达程度，初步探索慢性乙肝各中医证型间免疫反应状况规律。方法：采用双向电泳技术结合质谱对慢性乙肝5种中医证型患者（各30例）及正常对照组（10例）的血浆全蟹白进行比较蛋白质组学分析，然后扩大样本量，选取其中与肝脏损伤及机体免疫功能相关的差异表达蛋白质进行ELISA检测其变化规律。结果：①比较蛋白质组学分析发现在5种慢性乙肝中医证型中均存在明显规律性差异表达的蛋白点共有5个：（haptoglobin，HPT）、免疫球蛋白J链（immunoglobulinJ—chains，IGJ）、视黄醇结合蛋白（retinolbindingprotein，RBP）、C一反应蛋白（C—reactiveprotein，C1KP）、玻连蛋白（vitronectin，VN）。（~）ELISA检测发现在5种中医证型中与肝脏功能相关的蛋白质——RBP、HPT较正常对照组下调与机体免疫功能相关的蛋白质——IGJ较正常对照组上调的高低顺序是一致的。结论：慢性乙肝中医证型演变过程与机体体液免疫状态之间存在正相关性，肝脏病情越严重的中医证型其机体免疫功能越紊乱。
