We employed the research-to-practice consensus workshop (RTP; workshops held in
New York City and Tompkins County, New York, in 2013) model to merge researcher
and practitioner views of translational research priorities in palliative care.
In the RTP approach, a diverse group of frontline providers generates a research
agenda for palliative care in collaboration with researchers. We have presented
the major workshop recommendations and contrasted the practice-based research
priorities with those of previous consensus efforts. We uncovered notable
differences and found that the RTP model can produce unique insights into
research priorities. Integrating practitioner-identified needs into research
priorities for palliative care can contribute to addressing palliative care more
effectively as a public health issue.Over the past 2 decades, palliative care has become established as a promising approach
for addressing the needs of individuals with life-threatening illnesses from a holistic,
interdisciplinary perspective. For this project, we defined palliative care as an
approach that improves the quality of life of patients and families facing the problems
encountered in life-threatening illness by preventing and relieving suffering. Core
components of palliative care include providing relief from pain and other distressing
symptoms, affirming dying as a normal process, integrating psychological and spiritual
aspects of care, enhancing the quality of life of patients, and offering support systems
to patients and their families to help them live as fully as possible until death
occurs.Research suggests that palliative care results in positive patient outcomes, greater
patient and family satisfaction, and significant cost savings.1,2 The American Public Health Association, the
World Health Organization, and the Institute of Medicine3–6 have identified the
development of a robust palliative care delivery system as a key public health issue
because of the documented ability of palliative care to deliver effective and efficient
patient- and symptom-focused care to a growing population in need.In its 2013 report the American Public Health Association specifically detailed the
public health implications of palliative care, acknowledged the growing burden of
advanced chronic illness and disease in older adults, and recommended key steps to
address the problem. This policy statement called for federal, state, and local efforts
to promote effective symptom management in populations with serious illness or at the
end of life. Other recommended initiatives included the development of a palliative care
workforce, educational programs to improve uptake and use of palliative and hospice
care, and research funding to support the expansion of palliative care initiatives.
Achieving these goals will require moving beyond traditional medical practices to
include both policies and initiatives at the public health level.Despite the potential of palliative care to address the mental and physical health needs
of individuals with advanced illness, significant knowledge gaps impede its reach and
effectiveness. Reports from scientific bodies and consensus workshops have highlighted
weaknesses in the literature and called for more research on palliative care and
improved research methods.7–10 Thus, although both interest in and demand for
palliative care are increasing, reviews of the knowledge base continue to lament the
lack of research on many key issues.11,12Especially urgent is a research agenda that fits most closely with the needs of providers
who deliver palliative care. The systematic engagement of community practitioners in a
consensus process can lead to particularly useful and actionable recommendations for
research,13–15 which are greatly needed at this stage in the
development of the field. Therefore, to shed new light on research priorities in
palliative care, we used a structured, participatory method designed to solicit
practitioner input on research priorities: the research-to-practice consensus workshop
(RTP) model.16We employed the RTP approach to identify knowledge gaps and types of studies that should
be conducted to improve providers’ ability to deliver palliative care most
effectively. This model harnesses practice wisdom by engaging clinicians, agency staff,
and other practitioners with researchers in a process of articulating and refining
research questions and research priorities that honors scientific expertise and practice
wisdom. 相似文献

Links between Adolescents' Closeness to Adoptive Parents and Attachment Style in Young Adulthood 下载免费PDF全文
This study examined whether adolescents' closeness to adoptive parents (APs) predicted attachment styles in close relationships outside their family during young adulthood. In a longitudinal study of domestic infant adoptions, closeness to adoptive mother and adoptive father was assessed in 156 adolescents (M = 15.7 years). Approximately 9 years later (M = 25.0 years), closeness to parents was assessed again as well as attachment style in their close relationships. Multilevel modeling was used to predict attachment style in young adulthood from the average and discrepancy of closeness to adolescents' adoptive mothers and fathers and the change over time in closeness to APs. Less avoidant attachment style was predicted by stronger closeness to both APs during adolescence. Increased closeness to APs over time was related to less anxiety in close relationships. Higher closeness over time to either AP was related to less avoidance and anxiety in close relationships. 相似文献

Coenurosis is a disease of the central nervous system in sheep, caused by Coenurus cerebralis, the larval stage of Multiceps multiceps, which inhabits the small intestine of Canidae. A case of regurgitations in a 2.5 month old lamb with acute coenurosis is being reported. The lamb was presented with a sudden onset of ataxia and regurgitations for 10 days. The post-mortem examination revealed 4 immature C. cerebralis cysts between 0.5 and 1.5 cm in diameter located in the brainstem and cerebellum, and histopathological examination revealed multifocal pyogranulomatous meningoencephalitis, so a diagnosis of acute coenurosis was established. Thus, acute coenurosis should be included in the differential diagnosis of regurgitations in lambs. 相似文献
