A nurse/health care executive/architecture specialist and an artist/designer offer insights to creating environments that effectively support the delivery of care, the wellbeing of patients and their families, and the well-being of the health care workforce. The care environment is more than bricks, mortar, doors, windows, walls, and flooring. It is a sanctuary where healing can take place, where the spirit can be released, and where the provision of care, often fairly intimate, can happen through the connection between patient and care providers. Evidence-based design has brought forth the kind of inquiry and solutions that begin to address what an environment for healing requires. The interaction of built environment, staff, patients, families, and doctors is an overlapping ebb and flow that relies at its heart on the ability to hold all the parts as having equal priority. 相似文献

Results from the Philippine Quality Improvement Demonstration Study show that a policy that expands insurance coverage improves quality of care, as measured by clinical performance vignettes, among public physicians, and induces a spillover effect that improves quality among private physicians. 相似文献

Tourism resources are important foundation for the development of tourism industry. Grassland is not only a kind of important resource but also a great attraction to visitors. Therefore, the integrated development and sustainable utilization of grassland tourism resources are of great significance. This paper, based on the analysis of literatures and the current problems existing in grassland tourism, summarizes the speciality of grassland tourism development, deals with the problem of speciality, and raises the modes of regional development, product development and management. This paper takes Inner Mongolia, the famous grassland tourism destination as example and carries out empirical research. Based on the status quo of grassland tourism resources in Inner Mongolia, this study analyzes the character- istics of grassland tourism resources, the necessity and feasibility of integrated development, then proposes the following suggestions: idea for development, mode of development, regional cooperation, tourism products development, espe- cially the three modes of development based on the resources conditions - the mode of relying on market, the mode of combination aggregation and the mode of relying on quality. 相似文献
