BackgroundManaging nutrition in critically ill patients is an important intervention to promote healing. It is unknown whether the implementation of a protocol that guides enteral nutrition (EN) support is effective in improving the outcomes of critically ill patients. Furthermore, it is unknown whether a nurse‐driven protocol is more or less effective than a protocol not managed by nurses.Aims and objectivesThe purpose of this literature review is to determine the current state of the science regarding evidence‐based protocols for the administration and management of EN in critically ill patients.Search strategy, inclusion, and exclusion criteriaStudies were identified by searching the Cumulative Index to Nursing and Allied Health Literature Plus database for the terms “enteral nutrition AND nursing.” Studies with EN protocols for adult, critically ill patients published since 2011 were included. Studies without a protocol and those pertaining to paediatric, disease‐specific, medical‐surgical, or community‐based populations were excluded. A total of 10 studies meeting the inclusion criteria were identified.ConclusionsDefining and implementing both early initiation of EN and adequate titration to goal are important for achieving the maximum nutritional advantage. The highest benefit is also derived from identifying and delivering an individualized caloric and/or protein goal. A protocol increases standardization of practice in relation to these themes as well as the management of gastric residual volume, complications, and potentially for managing feeding interruptions. Because of the significant effects of nursing care on nearly all aspects of the management and delivery of EN, a nurse‐driven protocol may yield higher compliance and greater effectiveness than a protocol that is not nurse driven.Relevance to clinical practiceNurses are at the forefront of EN administration, although interprofessional collaboration remains paramount. Current practice must align with the best practice in the development and implementation of an EN protocol.
The Magnet® model encompasses structural empowerment, transformational leadership, exemplary professional practice, and new knowledge, innovations, and improvements. As the American Nurses Credentialing Center reminds us, great leaders, structures, and nurses lead to great knowledge, innovation, and outcomes. One organization experienced the wisdom in this model through restructuring the systemwide staff nurse councils. The authors describe the steps by which this restructuring was accomplished and some of the positive effects on the work environment.
To meet role expectations for nurses, nurses must feel empowered. Faculty contributions to the learning environment for nursing students are critical. A descriptive analysis of student perceptions of empowerment within the learning environment was conducted using a form of Kanter’s Conditions of Work Effectiveness Questionnaire; 203 participants from schools in 17 different states completed surveys. Subjects demonstrated moderate degrees of structural empowerment in their learning environment. This positive finding can be further investigated and used to fully prepare future nurses.
The shortage of frontline nursing staff and their managers in acute care organizations necessitates strategies to both use and recognize the unique knowledge and skills of these individuals. The authors describe one organization's successful implementation of a shared decision-making structure that promotes an empowering work environment in which professional fulfillment and personal satisfaction can flourish. With support and opportunity, leaders are developed across all levels of nursing.
What might braiding social justice orientations to teaching, learning, and educational change with collaborative inquiry-based professional development afford teachers, their students, and our communities? This article unpacks two professional development initiatives to articulate how inquiry co-constructed by and with teachers can take up diversity as generative. The Aboriginal Early Literacy and Curriculum for All projects involved iterative and critical examinations of practice and opportunities for educators to collaboratively consider and create practices that address contextual and social factors. Educators worked together to situate emerging knowledge and beliefs while also challenging the sources and consequences of assumptions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
