BackgroundEmergency Medicine/Critical Care Medicine (EM/CCM) trainees may obtain board certification through Internal Medicine (American Board of Internal Medicine [ABIM]), Surgery (American Board of Surgery [ABS]), and Anesthesiology (American Board of Anesthesiology [ABA]). However, EM/CCM trainees experience challenges, including: 1) additional training requirements and 2) an unwillingness to accept EM graduates by many programs.ObjectivesWe sought to: 1) compare EM/CCM knowledge acquisition to medicine (Internal Medicine [IM]/CCM), surgery (surgical critical care [SCC]), and anesthesiology (anesthesiology critical care medicine [ACCM]) Fellows at the local and national level using the Multidisciplinary Critical Care Knowledge Assessment Program (MCCKAP) in-service examination as an objective measure; and 2) compare American Board of Medical Specialties (ABMS) pass rates for EM/CCM.MethodsSingle-center retrospective analysis comparing scores obtained by EM/CCM on the MCCKAP examination with SCC and ACCM over a 10-year period. Scores are presented as means with standard deviations. We performed similar analysis on ABMS examination pass rates.ResultsThere were 117 MCCKAP scores (37 EM/CCM; 80 SCC and ACCM) evaluated. EM/CCM mean score 562.4 (SD 67.4); SCC and ACCM mean score 505.3, (SD 87.5) at the institutional level (p < 0.001). Similarly, EM/CCM scored higher than the national mean (562.4, SD 67.4 vs. 500 SD 100, p < 0.001). Nationally, ABIM-CCM board certification rate was 91.2% for 137 EM/CCM, compared with 93.2% for IM/CCM (p = 0.22); 28 EM/CCM have obtained ABA-CCM board certification with rates similar to ACCM (90.4 vs. 89.3%; p = 0.85).ConclusionsEM/CCM Fellows demonstrate successful knowledge acquisition both locally and at a national level. EM/CCM achieve ABMS pass rates similar to other CCM trainees. The current arbitrary additional training requirements placed on EM/CCM should be removed. 相似文献

目的了解广东省家庭医生式服务试点地区居民健康行为及影响因素,为开展健康教育提供依据。方法2015年7—10月抽样选取1010名家庭医生式服务试点地区居民进行问卷调查,以吸烟、饮酒、早餐、吃水果、锻炼及睡眠等6项行为为调查内容,同时选用P-CAT量表测量基层医疗服务质量。结果 6项行为方式共赋值12分,被调查者平均得分(8.72?0.65)分,得分从高到低依次为吃早餐、限酒、不吸烟、体育锻炼、吃水果和睡眠。多重线性回归分析结果显示:女性、已婚或慢性病患者的健康行为优于各对应组;收入对健康行为有正面影响;基层医疗服务可及性、服务提供综合性对健康行为有正向影响。结论试点地区居民整体健康行为较好。健康教育和健康促进应聚焦于合理膳食、锻炼及睡眠等健康行为;男性、单身或离异及低收入群体是重点关注的对象;提高基层医疗服务可及性和服务提供综合性有利于促进居民的健康行为。 相似文献

Phenomenon: Academic health centers face significant challenges trying to improve medical education while meeting patient care needs. In response to problems with traditional forms of didactic education, many residency programs have transitioned to Academic Half Day (AHD), a curricular model in which learning is condensed into half-day blocks. In this model, trainees have protected educational time free from clinical responsibilities. However, an understanding of the impact on attending physicians and patient care when residents depart clinical sites for learning activities has not been well described. We sought to explore attending physicians’ perspectives when residents depart clinical sites to attend AHD. Approach: We performed a qualitative study with a grounded theory approach using individual semistructured interviews (December 2016–April 2017) of attending physicians who worked at inpatient and emergency department clinical sites from which residents departed to attend AHD. We used the constant comparative method, generating codes using an iterative approach and continuing sampling until saturation was reached. Major themes were identified and disagreements were resolved by consensus. Findings: Fifteen attending physicians from 6 clinical services were interviewed. Data analysis yielded 5 themes: emotional strain of workload, technology and systems challenges, patient safety and care concerns, disrupted resident learning, and the challenge to optimize resident education. Attending physicians, already working on busy services, felt frustrated and perceived having an increased workload when residents departed for AHD. They were concerned about safely entering orders in the electronic health record, impeded patient workflow, and further disruption of resident schedules already disrupted by duty hour restrictions and continuity clinic. Attending physicians described the importance of experiential learning from caring for patients and from structured didactic learning; however, the optimal balance was uncertain. Insights: We found that attending physicians experienced significant emotional strain, faced technological challenges, and were concerned about impeded workflow and patient safety when residents departed clinical sites for AHD. This is likely to be true whenever residents are pulled out of the clinical setting for any reason. Educators need to partner with hospital administrators to provide appropriate support for attending physicians when residents leave clinical sites, evaluate the effectiveness of different educational models, and determine how structured learning activities fit into the overall curriculum. 相似文献

目的评价血液科白血病疾病护理中应用健康教育的临床效果,为白血病护理工作提供参考。方法选择医院收治的白血病患者,总计60例。进行白血病患者随机分组护理,对照组与试验组各30例白血病患者,分别采取常规护理和常规护理+健康教育,比较2组白血病患者的负性情绪、自我效能状况评分以及护理满意度、护理依从率。结果试验组白血病患者干预后SAS、SDS、GSES评分均明显优于对照组,护理满意度与护理依从率均明显高于对照组,指标差异具有统计学意义,P>0.05。结论血液科白血病治疗期间配合落实常规护理、健康教育可以在提高患者自我效能的同时提高患者的依从性,符合患者身心护理需求,整体护理效果显著。 相似文献

目的探讨工作坊模式在护生压疮护理带教中的应用效果,为临床护理带教提供参考。方法选取2018年7月—2019年6月在医院实习的120名护生作为研究对象,随机分为对照组和观察组,各60名护生。对照组采用传统带教法进行压疮培训,观察组采用工作坊教学模式进行培训。培训结束后比较两组护生压疮知识的掌握程度即理论考核、技能操作成绩,教学效果满意度。结果观察组护生对压疮知识的掌握程度即理论考核成绩、技能操作考核成绩远远高于对照组,两组差异具有统计学意义(P<0.05)。95%的观察组护生对工作坊教学模式的效果表示满意,认为工作坊教学模式能够提高学习的兴趣、主动性和临床实践能力,对临床工作有很大帮助。结论工作坊教学模式应用于压疮护理的临床带教,能让护生亲身体验压疮护理的过程,并参与其中,将理论与实践相结合,更好地活跃课堂气氛,启发护生思考,提高护生对压疮理论和技能的掌握,为临床实际工作中压疮护理质量的提高奠定基础。 相似文献
