Objectives: To identify the barriers and facilitators associated with the implementation of the nurse practitioner (NP) role in Ontario's public health units (PHUs), the NPs' job satisfaction, and the relationship between NP job satisfaction and practice dimensions., Methods: This descriptive study involved a postal survey of all NPs (N = 29) working in Ontario PHUs., Results: Twenty-eight (96.5%) NPs completed the survey. The facilitators to role implementation most often identified by the NPs were management support, the NPs' knowledge of the PHU programs, and access to PHU programs for their clients. The barriers most often cited were being the only NP working in the PHU, inadequate salary, and lack of coverage when the NP was away. When working with community physicians, the most common facilitators were the trust shown by physicians when making shared decisions and physician respect for the NP. The most common barriers were the unwillingness of specialist physicians to accept referrals from the NP and physicians' lack of understanding of the role. Overall, the NPs were satisfied with working in the PHU, satisfied with their collaborative relationship with physicians and minimally satisfied with their salaries., Conclusion: NPs have recently been introduced in PHUs in Ontario. A number of factors have facilitated role integration. At the same time, a number of barriers to their role implementation have been identified and if addressed, can contribute to the optimal utilization of this role in PHUs.

Health outcomes are becoming the currency of health care exchange, and a call for evidence dominates decision making at all levels. This discussion paper reviews methodological and sociopolitical barriers that impede the production and dissemination of outcome research in public health, with particular reference to nursing. Barriers to the production of high-quality research evidence include inaccessible graduate education and inadequate research funding. Also, randomized controlled trials (the ideal design for interventions studies) are uniquely difficult to implement for public health services. Practical and ethical difficulties arise in defining the intervention, implementing random allocation methods, selecting and measuring outcomes, and articulating adequate theoretical frameworks. When health care activity is defined as output, there is a tendency to exclude the ethical standing of preventive, supportive and communitarian functions. The production and interpretation of research results must remain part of a social, political and ethical debate, not a purely scientific one.

The purpose of this systematic overview was to summarize evidence about the effectiveness of adolescent suicide prevention curricula programs. A comprehensive search of published and unpublished literature resulted in retrieval of 11 relevant studies. The findings, of this overview indicate that there is currently insufficient evidence to support curriculum-based suicide prevention programs. The evidence suggests that there may be both beneficial and harmful effects of the programs on students. In most studies, knowledge related to suicide improved as a result of the programs. However, studies found both beneficial and harmful effects on attitudes related to suicide. One study found in increase in hopelessness and maladaptive coping for males following the intervention. The literature suggests that more broadly based comprehensive school health programs should be evaluated for their effectiveness in addressing the determinants of adolescent risk behaviour.

The purpose of this systematic overview was to assess the evidence for the effectiveness of public health nursing interventions when carried out by the strategy of home visiting. A search of published and unpublished literature resulted in retrieval of 108 articles; 77 articles were judged to be relevant. Validity criteria included method of allocation to the study groups, level of agreement to participate in the study, control for confounders, method of data collection (pretesting of data collection tools, blinding of data collectors to group allocation of study participants), quantitative measure of effect and percentage of participants available at follow-up. Using these criteria, 9 articles were judged to be strong, 5 moderate and 63 weak. There were no reported negative effects of home visiting in the 9 strong articles. Positive outcomes included improvement in children's mental development, mental health and physical growth; reduction in mother's anxiety, depression, and tobacco use; improvement in maternal employment, nutrition and other health habits; government cost saving; and reduced level of care required for the elderly.

An intersectoral immigrant health promotion project in Hamilton, Ontario is described. The project goal was to facilitate the entry of new immigrants to the Ontario health care system and equip them with knowledge and skills to strengthen their preventive and promotive health practices. A needs assessment preceded project development. The three phases of the project are described. The first phase commenced with the development of culturally sensitive health promotion resource materials to be used with immigrants enrolled in English as a Second Language Classes. In phase two, activities focussed on strengthening the ability of ESL teachers to incorporate a preventive and promotive health focus in their classes. The final phase shifted to a community-based project. During this phase, a core immigrant group developed their skills as health advocates for their immigrant community.
