  • Caring for Children in Immigrant Families: Vulnerabilities, Resilience, and Opportunities PEDIATRIC CLINICS OF NORTH AMERICA Linton, J. M., Choi, R., Mendoza, F. 2016; 63 (1): 115-?


    Demographics indicate that pediatricians increasingly care for children in immigrant families in routine practice. Although these children may be at risk for health disparities relating to socioeconomic disadvantage and cultural or linguistic challenges, immigrant families have unique strengths and potential for resilience. Adaptive and acculturation processes concerning health and well-being can be mediated by cultural media. Pediatricians have a professional responsibility to address the medical, mental health, and social needs of immigrant families. Advocacy and research at the practice level and beyond can further explore the unique needs of this population and evidence-based strategies for health promotion.

    Twitter is a tool for physicians to increase engagement of learners and the public, share scientific information, crowdsource new ideas, conduct, discuss and challenge emerging research, pursue professional development and continuing medical education, expand networks around specialized topics and provide moral support to colleagues. However, new users or skeptics may well be wary of its potential pitfalls. The aims of this commentary are to discuss the potential advantages of the Twitter platform for dialogue among physicians, to explore the barriers to accurate and high-quality healthcare discourse and, finally, to recommend potential safeguards physicians may employ against these threats in order to participate productively.

    Physicians can adhere to the principles of professionalism by practicing high-quality, evidence-based care and advocating for just and cost-effective distribution of finite clinical resources. To promote these principles, the National Physicians Alliance (NPA) initiated a project titled "Promoting Good Stewardship in Clinical Practice" that aimed to develop a list of the top 5 activities in family medicine, internal medicine, and pediatrics where the quality of care could be improved.Working groups of NPA members in each of the 3 primary care specialties agreed that an ideal activity would be one that was common in primary care practice, that was strongly supported by the evidence, and that would lead to significant health benefits and reduce risks, harms, and costs. A modification of nominal group process was used to generate a preliminary list of activities. A first round of field testing was conducted with 83 primary care physicians, and a second round of field testing with an additional 172 physicians.The first round of field testing resulted in 1 activity being deleted from the family medicine list. Support for the remaining activities was strong. The second round of field testing showed strong support for all activities. The family medicine and internal medicine groups independently selected 3 activities that were the same, so the final lists reflect 12 unique activities that could improve clinical care.Physician panels in the primary care specialties of family medicine, internal medicine, and pediatrics identified common clinical activities that could lead to higher quality care and better use of finite clinical resources. Field testing showed support among physicians for the evidence supporting the activities, the potential positive impact on medical care quality and cost, and the ease with which the activities could be performed. We recommend that these "Top 5" lists of activities be implemented in primary care practice across the United States.

  • Maintaining health sector collaborations between United States non-governmental organizations and North Korea through innovation and planning. Prehospital and disaster medicine Yim, E. S., Choi, R. Y., VanRooyen, M. 2009; 24 (3): 153-160


    Humanitarian agencies in North Korea operate within a complex sociopolitical environment historically characterized by a baseline of mistrust. As a result of operating within such a heated environment, health sector collaborations between such agencies and the North Korean government have followed unpredictable courses.The factors that have contributed to successful programmatic collaborations, as perceived by United States non-governmental organizations (NGOs) and North Korean officials were investigated.A qualitative, multi-case, comparative, research design using semistructured interviews was used. Expert North Korean informants were interviewed to generate a list of factors contributing to programmatic success, defined as fulfilling mutually established objectives through collaboration. The North Korean informants were asked to identify US NGOs that fulfill these criteria ("mission-compatible NGOs"). Representatives from all of the mission compatible NGOs were interviewed. All informants provided their perspectives on the factors that contributed to successful programmatic collaborations. The interviews were recorded, transcribed, and analyzed for thematic content.North Korean informants identified six mission-compatible US NGOs. The North Korean and US NGO informants provided a number of factors that contributed to successful programs. These factors were grouped into the following themes: (1) responsiveness to North Korean requests; (2) resident status; (3) program monitoring; (4) sincerity (apolitical objectives); (5) information gathering; and (6) interagency collaboration.Some US NGOs have devised innovative measures to work within a unique set of parameters in North Korea. Both US NGOs and North Korean authorities have made significant concessions to maintain their programmatic partnerships. In this manner, seasoned collaborators have employed creative strategies and a form of health diplomacy to facilitate programmatic success in North Korea by building trust within a complex sociopolitical space.
