In 2015, the Canadian Counsel of Registered Nurse Regulators released a report that identified entry-to-practice core competencies for adult, family/all ages, and pediatric nurse practitioners (NPs) across Canada. The report is expected to guide future decisions about NP entry-to-practice examinations and allow for Canadian Counsel of Registered Nurse Regulators member organizations to develop pan-Canadian requirements for licensure. Optimistically, it could set the stage for a national approach to NP education. This is an opportune time to highlight various stakeholders' call for increased mental health education for NPs and identify challenges and promising strategies for reaching that goal. 相似文献

目的:比较观察局麻单孔腹腔镜双极电凝输卵管绝育术与经腹近端抽芯包埋输卵管绝育术对卵巢功能的影响。方法:在贵州省内14个县随机抽取2014年10月~2015年10月行上述两种输卵管绝育术妇女各100例,测定卵巢基础激素(FSH、LH和E2)。结果:共133例研究对象进入观察,其中腹腔镜输卵管绝育术组82名,年龄28.84±4.02岁;开腹输卵管绝育术组51名,年龄27.61±4.20岁。两组术后1个月的卵巢基础性激素平均水平无统计学改变;术后1个月基础FSH≥10U/L、基础FSH/LH升高2的比例开腹组明显高于腹腔镜组。结论:腹腔镜输卵管绝育术近期对卵巢功能的影响小于开腹输卵管绝育术。 相似文献

Problem: Many medical schools are modifying curricula to reflect the rapidly evolving health care environment, but schools struggle to provide the educational informatics technology (IT) support to make the necessary changes. Often a medical school's IT support for the education mission derives from isolated work units employing separate technologies that are not interoperable. Intervention: We launched a redesigned, tightly integrated, and novel IT infrastructure to support a completely revamped curriculum at the Vanderbilt School of Medicine. This system uses coordinated and interoperable technologies to support new instructional methods, capture students' effort, and manage feedback, allowing the monitoring of students' progress toward specific competency goals across settings and programs. Context: The new undergraduate medical education program at Vanderbilt, entitled Curriculum 2.0, is a competency-based curriculum in which the ultimate goal is medical student advancement based on performance outcomes and personal goals rather than a time-based sequence of courses. IT support was essential in the creation of Curriculum 2.0. In addition to typical learning and curriculum management functions, IT was needed to capture data in the learning workflow for analysis, as well as for informing individual and programmatic success. We aligned people, processes, and technology to provide the IT infrastructure for the organizational transformation. Outcomes: Educational IT personnel were successfully realigned to create the new IT system. The IT infrastructure enabled monitoring of student performance within each competency domain across settings and time via personal student electronic portfolios. Students use aggregated performance data, derived in real time from the portfolio, for mentor-guided performance assessment, and for creation of individual learning goals and plans. Poorly performing students were identified earlier through online communication systems that alert the appropriate instructor or coach of low quiz grades or missed learning goals. Graphical and narrative displays of a student's competency performance across courses and clinical experiences informed high-stake decisions made about student progress by the promotions committee. Similarly, graphical display of aggregate student outcomes provided education leaders with information needed to adjust and improve the curriculum. Lessons Learned: With the alignment of people, processes, and technology, educational IT can facilitate transformational steps in the training of medical students. 相似文献

Aim. To report the development and psychometric testing of the Behavioral Health Care Competency survey, designed to measure hospital nurse perceptions of behavioral healthcare competency. Background. Hospital nurses working in general or other non‐psychiatric units may lack behavioral healthcare competency to manage disruptive behaviours associated with mental illnesses. Design. Instrument development. Method. A nurse study team including clinical experts and nurse researchers from three community hospitals in southern California (USA) reviewed content validity of each item and the 31‐item instrument and created a behavioral health care competency conceptual model based on the nursing process. Separate institutional review board permissions were obtained from each hospital. The study team collaborated in the timing of survey administration (November 2010), analysis of the results and survey validation. Results. A total of 844 nurses completed the survey, representing approximately 23–41% of eligible nurses from each hospital. Using principal component analysis with varimax rotation, 23 items led to a factor structure with four components. Four subscales with adequate alpha coefficients were formed: Resource Adequacy, Patient Assessment, Practice/Intervention Competency, and Psychotropic Recommendation. Conclusion. The 23‐item hospital nurse Behavioral Health Care Competency survey is an adequate and valid newly developed instrument. Further testing with diverse samples is needed to strengthen generalizability and address unique and specialized nursing care needs. 相似文献

We compared the Sanger sequencing and the commercial INNO-LiPA® HBV assay for the routine detection of precore (PC) and basal core promoter (BCP) mutations of hepatitis B virus in chronically infected patients. The overall agreement rate between assays was 94.2% and 98.8% for the detection of PC and BCP mutations, respectively. 相似文献
