The Intervention Wheel is a population-based practice model that encompasses three levels of practice (community, systems, and individual/family) and 17 public health interventions. Each intervention and practice level contributes to improving population health. The Intervention Wheel, previously known as the Public Health Intervention Model, was originally introduced in 1998 by the Minnesota Department of Health, Section of Public Health Nursing. The model has been widely disseminated and used throughout the United States since that time. The evidence supporting the Intervention Wheel was recently subjected to a rigorous critique by regional and national experts. This critical process, which involved hundreds of public health nurses, resulted in a more robust Intervention Wheel and established the validity of the model. The critique also produced basic steps and best practices for each of the 17 interventions. Part I describes the Intervention Wheel, defines population-based practice, and details the recommended modifications and validation process. Part II provides examples of the innovative ways that the Intervention Wheel is being used in public health/public health nursing practice, education, and administration. The two articles provide a foundation and vision for population-based public health nursing practice and direction for improving population health.

In a changing and complex health care system, public health nurses face challenges to explain their work and contributions to health outcomes. In response to this need, the Minnesota Department of Health, Section of Public Health Nursing, initiated a process to describe public health nursing interventions. The Public Health Nursing Interventions (PHI) Model was developed through a collaborative process by public health nurses at the state and local levels. The purpose of the model was to define more clearly the practice of public health nursing and to describe better the work of public health nurses at the community and systems levels. The PHI model identifies 17 interventions and provides practice examples at the systems, community and individual/family levels. The model defines a broader view of the mission and scope of public health nursing. Practice examples are given for agency staff, administrators, educators, and policy makers.

Norwegian health professionals, elderly people and family members experience ethical problems involving end-of-life decision making for elders in the context of the values of Norwegian society. This study used ethical inquiry and qualitative methodology to conduct and analyze interviews carried out with 25 health professionals, six elderly people and five family members about the ethical problems they encountered in end-of-life decision making in Norway. All three participant groups experienced ethical problems involving the adequacy of health care for elderly Norwegians. Older people were concerned about being a burden to their families at the end of their life. However, health professionals wished to protect families from the burden of difficult decisions regarding health care for elderly parents at the end of life. Strategies are suggested for dialogue about end-of-life decisions and the integration of palliative care approaches into health care services for frail elderly people.

Using a conceptual framework and method combining ethical enquiry and phenomenology, we asked 73 senior baccalaureate nursing students to answer two questions: (1) What is nursing students' experience of an ethical problem involving nursing practice? and (2) What is nursing students' experience of using an ethical decision-making model? Each student described one ethical problem, from which emerged five content categories, the largest being that involving health professionals (44%). The basic nature of the ethical problems consisted of the nursing students' experience of conflict, resolution and rationale; 85% of the students stated that using an ethical decision-making model was helpful. Although additional research is needed, these findings have important implications for nursing ethics education and practice.

The Johns Hopkins Model and the Academic Center for Evidence-Based Practice Star Model emphasize the processes of finding and evaluating evidence that is likely to appeal to nursing educators. Organizations may prefer the Promoting Action on Research Implementation in Health Services Framework, Advancing Research and Clinical Practice Through Close Collaboration, or Iowa models for their emphasis on team decision-making. An evidence-based practice model that is clear to the clinician and fits the organization will guide a systematic approach to evidence review and practice change.

Planning for EBP change must address barriers and facilitators to practice change and emphasize the benefit for patients and value of the practice change to nurses.

In response to critical care nurses' perceptions of increasing stress and conflict in difficult end-of-life (EOL) situations, the researchers conducted a study to identify perceived obstacles, supports, and knowledge needed to provide quality EOL care. The conclusions were as follows: (1) families and patients need clear, direct, and consistent information to make EOL decisions; (2) physician-related issues affect nurses' ability to provide quality EOL care; (3) critical care nurses need more knowledge, skill, and a sense of cultural competency to provide quality care; and (4) having properly completed advance directives can reduce confusion about the goals of care. Recommendations for improving EOL care were made as a result of the study.

Student means for items on educational practices and satisfaction and confidence in learning were all between agree and strongly agree on a 5-point scale of agreement (n = 21). CONCLUSlON: The end-of-life simulation experience created an opportunity for nursing students to gain confidence in their ability to provide palliative nursing care.
