Resources to enhance evidence-based nursing practice.

Evidence-based practice means integrating the best available research evidence with information about patient preferences, clinician skill level, and available resources to make decisions about patient care. Barriers to the use of research-based evidence occur when time, access to journal articles, search skills, critical appraisal skills, and understanding of the language used in research are lacking. Resources are available to overcome these barriers and support an evidence-based nursing practice. This article highlights available resources and describes strategies that nurses can use to develop and sustain an evidence-based nursing practice.

Randomized trials versus observational studies in adolescent pregnancy prevention.

The objective of this study is to compare the results of randomized trials and observational studies of interventions to prevent adolescent pregnancy. We identified published and unpublished reports through computerized searches of CATLINE, CINAHL, CONFERENCE PAPERS INDEX, DISSERTATION ABSTRACTS ONLINE, EMBASE, ERIC, MEDLINE, NTIS, POPLINE, PsycINFO, and SOCIOLOGICAL ABSTRACTS; manual searches of eight relevant journals; reference lists from primary articles; and contact with content experts. We included randomized trials and observational studies that evaluated the impact of primary prevention interventions including sex education classes, school-based clinics, free-standing clinics, physician/nurse practitioner practice-based service, improved access, and community-based programs on four outcomes: sexual intercourse, birth control use, responsible sexual behavior, or pregnancy in adolescents. One investigator abstracted the data and a second conducted a detailed review of the abstraction. We identified 13 randomized trials and 17 observational studies. We generated estimates of the impact of the interventions separately for males and females for all four outcomes for both observational studies and randomized trials. For six of the eight outcomes the summary odds ratios for the observational studies showed a significant intervention benefit (P<0.05) while the randomized trials did not show a benefit for any outcome in either females or males. The difference between the results of the observational studies and randomized trials was statistically significant in two of the eight outcomes (P<0.05 for initiation of intercourse and pregnancy in females). Observational studies yield systematically greater estimates of treatment effects than randomized trials of adolescent pregnancy prevention interventions. Public policy or individual patient treatment decisions should be based on observational studies only when randomized trials are unavailable and only with careful consideration of possible biases.

Consortium approach for nurse practitioner education.

In 1995, a 10-university consortium approach to deliver a post-baccalaureate primary care nurse practitioner programme funded by the Ontario Ministry of Health was launched throughout Ontario, Canada. A combination of traditional and distance teaching methods, in English and French, were used. A 5-year research project was initiated to evaluate the entire programme, the effect of nurse practitioners on patient and health-care system outcomes and examine practice patterns. Participants included deans and directors (n = 10), regional co-ordinators (n = 5) and course developers, some of whom were also course professors (n = 8). This article is a report of the evaluation of the consortium programme after the first year from the perspective of groups involved in implementation and delivery. Results of qualitative analyses of participant perceptions from researcher-led focus groups and asynchronous electronic interviews provided the framework for the evaluation, and revealed the rationale for the consortium method, strengths, limitations and recommendations. Sharing ideas, resources and delivery and increased student access in remote areas were perceived as positive outcomes. Limitations included the short time period to develop programme content, identify and plan for distance education resources, and too little communication between universities and students. Researchers concluded that the consortium approach was effective for nurse practitioner education. Key factors identified for programme planning were communication, resources, curriculum and workload. Included among the recommendations was to allow sufficient time for role and course development before beginning a similar programme.

Willingness to pay for periodontal therapy: development and testing of an instrument.

OBJECTIVES: The objective of this study was to develop and test the feasibility and validity of a willingness to pay (WTP) tool in a dental setting. METHODS: A questionnaire measured individuals' preferences among alternative treatments for periodontal disease and the maximum they would be willing to pay for their treatment of choice in terms of dental insurance premiums. The questionnaire provides detailed information, in probabilistic terms, of the risks and benefits of treatment choices for moderate to advanced adult periodontitis. It was pilot tested on 23 periodontal patients and 18 dental school faculty and staff. RESULTS: The majority (92.6%) felt the questionnaire was an accurate representation of treatments and outcomes, establishing face and content validity. In terms of construct validity, four hypotheses were tested: (1) manipulation of the outcomes of the preferred treatment led to a predictable shift in preferences for 38 subjects (92.7%); (2) although periodontal patients were not more likely to choose periodontal surgery than nonpatients (P = .14), those with a history of surgery were more likely to choose surgery again (P = .06); (3) WTP was positively related to income level (P = .05); and (4) subjects were willing to pay more for coverage for themselves than for others. Periodontal surgery was the preferred treatment for moderate to advanced periodontal disease, and was more strongly preferred than other choices (i.e., a higher WTP) for all income groups. The intraclass correlation coefficient for treatment preferences was 0.95 (P < .001) and the kappa for WTP was 0.78 (P < .001). CONCLUSION: This pilot study supports some of the criteria concerning validity of the WTP questionnaire to measure preferences for alternative periodontal therapies. Further testing on larger samples is required to confirm these results.

The neonatal nurse practitioner.

Neonatal nurse practitioners have been introduced into tertiary level neonatal intensive care units in the United States, Canada, and the United Kingdom in response to the increased survival rates of extremely low birth weight infants, the short-age of physicians, and the nursing profession's emphasis on development of advanced nursing practice roles. This brief review summarizes the recent research related to the facilitating and constraining factors that influence the role; the safety, effectiveness, and cost of the role; the impact of this role on other members of the health care team; and the satisfaction of those in the role.

Evidence-based nursing: an introduction.

The Art & Science section of Nursing Standard this week is devoted to encouraging nurses to use evidence in their practice. As well as publishing some of the papers from the recent Evidence-Based Nursing conference in London, this report is based on the editorial which appeared in the pilot issue of Evidence-Based Nursing, a new journal jointly published by the BMJ Publishing Group and the RCN Publishing Company. It highlights the importance of using evidence in practice and explores the role of the new journal, which will be launched in November 1997, in helping nurses to achieve this aim.

Do nurses have the information resources and skills for research utilization?

While access to information resources and the skills to use them do not ensure that nurses will use nursing research in their practice, they are important facilitators. Mailed questionnaires to assess existing information resources, the information management skills of nurses, and what additional resources and training are required were returned by 67 of the 71 vice-presidents or directors of nursing in hospitals in two regions of Ontario. The two regions have similar information resources, nursing staff with research expertise, and opportunities for training in research and information management but there is variation among hospitals. Most vice-presidents agreed that nurses need better information resources and skills to access and evaluate professional literature. The rapidly developing field of information technology, including the Internet, provides potential for sharing resources and expertise. Nursing administrators can minimize barriers and help staff nurses recognize that information management skills enhance professional development and improve patient care.

The research utilization process: the use of guided imagery to reduce anxiety.

In the rapidly changing health care environment, nurses need to keep current with developments, assess their applicability to practice, and make changes where appropriate. There is evidence that nursing research is underutilized and that a considerable gap exists between nursing research and practice (Bostrum & Suter, 1993; Brett, 1987; Sokop & Coyle, 1990). The objectives of a study carried out on a bone marrow transplant unit in a teaching hospital were to: (1) by introducing a framework for research-based care, enhance research utilization in a selected setting, and (2) evaluate the outcomes of research utilization on a specific clinical nursing problem chosen by nurses and researchers. This paper describes the research utilization process and its outcomes, presents an evaluation of the participatory approach from the perspective of the participating nurses, and discusses facilitators and barriers to research utilization. Guided imagery was the intervention used to decrease patient anxiety.

Teaching nursing students evidence-based nursing.

Nurse educators face many challenges in the current healthcare environment. Educational methods, philosophies, and the content of curricula need to be reexamined to meet the needs of professional nurses who will practice in the next millennium. Evidence-based nursing is one approach that may enable future healthcare providers to manage the explosion of new literature and technology and ultimately may result in improved patient outcomes. The authors provide an introduction to evidence-based nursing as well as a description of the process in two separate undergraduate nursing programs.

RN and RPN decision making across settings.

Nursing decision making was a focus of the Province-Wide Nursing Project (PWNP), a 3-year project to promote best nursing practice. In much of the growing literature on nursing decision making, it is assumed that there are differences in the way RNs and RPNs make decisions. However, there is little scientific evidence to support this assumption. The RN and RPN decision making across settings questionnaire was completed by nurses employed in the 23 agencies of the 4 Participating Complexes taking part in the project. The survey questions were subjected to factor analysis and reduced to five factors. Results revealed measurable differences between the way that RNs and RPNs made decisions. Both RNs and RPNs reported making decisions frequently and experiencing little difficulty in making them. However, there were statistically significant differences in the frequency with which RNs and RPNs perceived they made decisions and the difficulty they found in making them. To plan effective health care, it is important to take account of the strengths of different health care workers. There is a need for further research to investigate the reasons behind the differences revealed in these findings.

Practice patterns of acute care nurse practitioners.

This study was undertaken to examine the practice pattern of nurse practitioners employed in Ontario acute care settings. A descriptive design, incorporating quantitative and qualitative methods for data collection, was used. The acute care nurse practitioners' practice pattern varied in terms of scope of practice, model guiding practice, reporting relations, and extent of role implementation. Role implementation encompassed activities representing the four role components: clinical practice, education, administration or management, and research. The acute care nurse practitioners engaged most frequently in the clinical component of the role. They performed medical and advanced nursing functions. They emphasized that they do not work in isolation and that they do not replace physicians or residents.

Implementation of the primary care nurse practitioner role in Ontario.

The purpose of this descriptive study was to examine the implementation of the nurse practitioner role in primary care settings. Nurse practitioners who were certified by the College of Nurses of Ontario as Extended Class were surveyed. The questionnaire inquired about the nurse practitioners' professional characteristics, employment settings, scope of practice, practice pattern, and satisfaction with their role. The majority of the 166 respondents working as nurse practitioners were Baccalaureate prepared; has been in the role for a relatively short period of time; were employed in community health centers; and were able to practice to their full potential, within the expanded scope of practice. They saw patients who are primarily healthy or presenting with acute minor illness, and provided care with an emphasis on wellness. They were satisfied with their role. Directions for future research are presented.

Organizational factors influencing nurse practitioners' role implementation in acute care settings.

The purpose of this study was to explore the influence of organizational factors on the Acute Care Nurse Practitioner (ACNP) role implementation. A descriptive correlational design, incorporating quantitative and qualitative methods for data collection was used. The sample of convenience consisted of 57 ACNPs assigned to various medical and surgical programs within acute care hospitals. Ten ACNPs participated in the unstructured qualitative interviews. In addition to the interviews, data pertinent to various organizational factors, including role formalization, receptivity of the role by others, perceived autonomy, role strain, and additional factors that may interfere with role implementation, were collected through a self-report structured questionnaire. A four-diary day was completed to gather data on role implementation. Descriptive and correlational statistics were used to analyze the quantitative data. The qualitative data were content analyzed. The ACNPs engaged most frequently in activities reflective of the clinical practice component of the role and less frequently in the non-clinical components (i.e., education, administration, and research). Results of the quantitative and qualitative analyses indicated that lack of formal clear job description, conflicting demands and expectations, lack of receptivity of the role by others, lack of autonomy, and increased workload were negatively correlated with the ACNP role implementation. The ACNP role implementation varies across practice settings. This variability should be accounted for when examining outcomes of ACNP care.

Healthcare restructuring: the impact of job change.

Restructuring, particularly redeployment and job change, had a dramatic impact on the working conditions and practices of nursing personnel. This study was conducted to determine whether nurses (RNs and RPNs) who experienced job change perceived their work-lives differently than those who did not undergo job change and, whether nurses who experienced different types of job change (new role, new unit, or new hospital) varied in their perceptions. A questionnaire exploring themes relevant to redeployment was administered to all nurses (N = 3,408) in two large teaching hospitals that had undergone restructuring. The response rate was 50.7% (n = 1,728). Of the responses, 1,662 were used in the analysis. T-tests and ANOVAs were used to compare groups of nurses. Nurses who changed their jobs perceived their commitment to the organization, their work environment and quality of care differently than those who did not change jobs. Nurses with different types of job change differed in their organizational commitment, perceptions of work-related injuries, attitudes towards job change, need for orientation and new knowledge, and feelings about the health care team. Results will assist managers to address the specific needs of nurses with different experiences of job change in the restructured workplace.

Completing the picture: adolescents talk about what's missing in sexual health services.

This qualitative study was conducted to learn adolescents' opinions about sexual health services and strategies to improve their delivery. Sixteen 1.5-hour, same-sex focus groups were conducted in one rural and one urban high school in each of two Ontario regions. In total, 83 students (49 females and 34 males) participated in the study. Topics were: sources and quality of sexual health information, knowledge and use of sexual health services, gender differences, factors that influence sexual behaviour, and suggestions for improving sexual health services. The adolescents reported that sex education focussed too much on "plumbing" and was often provided by teachers with whom they felt uncomfortable discussing sexual issues. Peers and media were their main sources of information although they acknowledged that these were not always accurate. The participants had limited knowledge of the services available. Many of their comments reflected traditional gender differences. Peers, and for females, partners and parents influenced sexual decision-making. The participants made numerous suggestions for improving sexual health services.

Evaluation research in public health: barriers to the production and dissemination of outcomes data.

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.

Adolescent sexual behaviour: results from an Ontario sample. Part II: Adolescent use of protection.

This paper reports the frequency of use of protection and rates of birth control pill/condom use by age and gender among a large, sexually active group of Ontario adolescents who were followed from 12 to 17 years of age. The sample consisted of the 759 males and 690 females who reported engaging in sexual intercourse during the McMaster Teen Project. Significantly more females aged 15-17 years reported always using a method of protection, and using the birth control pill. Condom use was more frequent among males at all ages, but reached statistical significance at ages 12, 13 and 17 years. Although the numbers reporting no use of protection decreased with age, by 17 years 36% of males and 33% of females continued to report no use of protection. Large numbers of sexually active Ontario adolescents continue to be vulnerable to pregnancy, STDs and AIDS.
