Electronic health records and support for primary care teamwork

Objective Consensus that enhanced teamwork is necessary for efficient and effective primary care delivery is growing. We sought to identify how electronic health records (EHRs) facilitate and pose challenges to primary care teams as well as how practices are overcoming these challenges.Methods Practices in this qualitative study were selected from those recognized as patient-centered medical homes via the National Committee for Quality Assurance 2011 tool, which included a section on practice teamwork. We interviewed 63 respondents, ranging from physicians to front-desk staff, from 27 primary care practices ranging in size, type, geography, and population size.Results EHRs were found to facilitate communication and task delegation in primary care teams through instant messaging, task management software, and the ability to create evidence-based templates for symptom-specific data collection from patients by medical assistants and nurses (which can offload work from physicians). Areas where respondents felt that electronic medical record EHR functionalities were weakest and posed challenges to teamwork included the lack of integrated care manager software and care plans in EHRs, poor practice registry functionality and interoperability, and inadequate ease of tracking patient data in the EHR over time.Discussion Practices developed solutions for some of the challenges they faced when attempting to use EHRs to support teamwork but wanted more permanent vendor and policy solutions for other challenges.Conclusions EHR vendors in the United States need to work alongside practicing primary care teams to create more clinically useful EHRs that support dynamic care plans, integrated care management software, more functional and interoperable practice registries, and greater ease of data tracking over time.     

犀角地黄汤加味通过NF-κB信号通路对败血症导致的炎症和肺损伤的影响

目的研究犀角地黄汤加味对败血症导致的炎症和肺损伤的影响,探讨其对核转录因子-κB(NF-κB)信号通路的调控作用。方法制备败血症小鼠模型,测量血清中乳酸脱氢酶(LDH)反映败血症小鼠的器官损伤程度;HE染色观察败血症小鼠肺组织病理学变化;酶联免疫吸附法测定肺组织中细胞因子白细胞介素-6(IL-6)、白细胞介素-1β(IL-1β)、小鼠巨噬细胞炎症蛋白-2(MIP-2)水平;免疫组化法检测肺组织中粒细胞分化抗原-1(Gr-1)的阳性表达;TUNEL法分析败血症小鼠肺中的TUNEL阳性细胞数量;Western blotting法检测肺组织中NF-κB p65蛋白表达。结果犀角地黄汤加味减轻了败血症小鼠的炎症反应和肺损伤程度,以及嗜中性粒细胞浸润。犀角地黄汤加味显著减少了败血症小鼠肺中的TUNEL阳性细胞数量。结论犀角地黄汤加味可以减轻败血症导致的炎症和肺损伤,可能是通过抑制NF-κB信号通路发挥作用。     

老年患者两种浅静脉穿刺方法比较

目的探讨老年患者最佳静脉穿刺方法。方法随机选择400例60岁以上心血管疾病患者,分别采取正面和侧面穿刺方法,分析不同穿刺方法对穿刺成功率、耗时数、疼痛度的影响。结果正面穿刺比侧面穿刺成功率高(P<0.05);正面穿刺较侧面穿刺疼痛度低(P<0.05);正面穿刺耗时数与侧面穿刺相比差异无统计学意义(P>0.05)。结论老年患者血管硬化、弹性下降,适合采用浅静脉正面穿刺。     

Single course versus maintenance bacillus Calmette-Guerin therapy for superficial bladder tumors: a prospective, randomized trial

A total of 42 patients with recurrent superficial bladder tumors or carcinoma in situ entered a prospective, randomized trial to compare the efficacy of bacillus Calmette-Guerin therapy with and without quarterly maintenance instillations of bacillus Calmette-Guerin. Maintenance therapy did not reduce further bladder tumor recurrence rates or the interval to recurrence in patients who responded to the initial course of therapy. However, prolongation of toxicity was observed with maintenance bacillus Calmette-Guerin therapy.
