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.

Background: Several groups have outlined methodologies for systematic literature reviews of the effectiveness of interventions. The Effective Public Health Practice Project (EPHPP) began in 1998. Its mandate is to provide research evidence to guide and support the Ontario Ministry of Health in outlining minimum requirements for public health services in the province. Also, the project is expected to disseminate the results provincially, nationally, and internationally. Most of the reviews are relevant to public health nursing practice., Aims: This article describes four issues related to the systematic literature reviews of the effectiveness of public health nursing interventions: (1) the process of systematically reviewing the literature, (2) the development of a quality assessment instrument, (3) the results of the EPHPP to date, and (4) some results of the dissemination strategies used., Methods: The eight steps of the systematic review process including question formulation, searching and retrieving the literature, establishing relevance criteria, assessing studies for relevance, assessing relevant studies for methodological quality, data extraction and synthesis, writing the report, and dissemination are outlined. Also, the development and assessment of content and construct validity and intrarater reliability of the quality assessment questionnaire used in the process are described., Results: More than 20 systematic reviews have been completed. Content validity was ascertained by the use of a number of experts to review the questionnaire during its development. Construct validity was demonstrated through comparisons with another highly rated instrument. Intrarater reliability was established using Cohen's Kappa. Dissemination strategies used appear to be effective in that professionals report being aware of the reviews and using them in program planning/policymaking decisions., Conclusions: The EPHPP has demonstrated the ability to adapt the most current methods of systematic literature reviews of effectiveness to questions related to public health nursing. Other positive outcomes from the process include the development of a critical mass of public health researchers and practitioners who can actively participate in the process, and the work on dissemination has been successful in attracting external funds. A program of research in this area is being developed.

A descriptive study was designed to gain an understanding of the research needs, perceptions of barriers to research utilization, and attitudes towards systematic reviews of decision-makers in public health at the level of systems planning. Public-health consultants and managers in Ontario were surveyed about barriers to research utilization and awareness of and attitudes towards systematic reviews as a method of/vehicle for research transfer. Access to 5 completed reviews was provided in summary, abstract, and full form, and on diskette, hard copy, and Internet. A follow-up survey at 3 months assessed use, relevance, application, and further dissemination of the reviews. A total of 242 people in positions of public-health policy and decision-making participated. Respondents reported a great, largely unmet, need for research evidence. They viewed systematic reviews as likely to overcome the barriers to research use related to critical appraisal, time, timeliness, availability, cost and credibility, but not the barriers related to policy climate, authority, or implementation resources. Three months after requesting a review, 93% said they would follow it up; 91% remembered receiving it, and 71% of these had read it while 23% stated it played a part in program planning or decision-making.

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.

In an age of cost containment, agency partnerships have become an essential element for future planning and program implementation. This paper describes a trisectoral collaboration of a hospital, health department, university and school of nursing to compare the efficacy and efficiency of referral decisions of hospital staff nurses to those of the public health liaison nurses (LNs). A process to identify decision criteria was undertaken and an educational programme was designed to assist the staff nurses with the referral process and to assure consistency of decision making. The two groups were then compared. The results of the study found staff nurses, using the decision criteria, identified more patients who required public health nursing visits than did the liaison nurses, refusal rate of the patients to participate was no different, staff nurses cost less than LNs and job satisfaction was not significantly altered for either group. In addition to providing information to guide administrative and clinical decision making, the project also provided a learning experience for the staff of three agencies in conducting research and in using evidence-based practice to change traditional practice.

The purpose of this study was to compare hospital staff nurses to public health liaison nurses in the accuracy and cost of postpartum referrals for public health nursing follow-up in the community. In the before phase of the study, public health liaison nurses assessed 304 mothers to determine the need for a follow-up visit by the public health nurse. In the after phase, staff nurses assessed 326 mothers. Public health nurses, unaware of the identity of the referring nurse and the referral decision, judged whether their visit had been required. Staff nurses correctly identified a higher proportion of referrals requiring public health nurse follow-up than liaison nurses. Although they referred more clients who did not require a public health nurse visit, costs of referrals by staff nurses remained lower.

Public health nurses (PHNs) have been attached to family doctors' offices as one mode of organizing the delivery of nursing services in the community. However, different nurses function in different roles on a continuum from generalist to liaison. A descriptive study was undertaken to determine the most effective role for PHNs attached to family physicians' offices. Outcomes for both physicians and nurses were satisfaction with the role of the PHN, appropriateness of referrals, and accessibility for consultation. These outcomes were compared relative to the rating of PHNs of their role. A cohort of physicians without attachment PHNs were also surveyed to compare responses on the same criteria. The majority of nurses described their role generalist. This role was related to greater satisfaction for nurses and the physicians with whom they worked. Satisfaction with PHN service, ease of arranging consultation with PHN, and appropriateness of referrals from PHNs was greater for physicians who had the attachment than those who used the usual service.
