Devolution to democratic health authorities in Saskatchewan: an interim report.

BACKGROUND: In 1995 Saskatchewan adopted a district health board structure in which two-thirds of members are elected and the rest are appointed. This study examines the opinions of board members about health care reform and devolution of authority from the province to the health districts. METHODS: All 357 members of Saskatchewan district health boards were surveyed in 1997; 275 (77%) responded. Analyses included comparisons between elected and appointed members and between members with experience as health care providers and those without such experience, as well as comparisons with hypotheses about how devolution would develop, which were advanced in a 1997 report by another group. RESULTS: Most respondents felt that devolution had resulted in increased local control and better quality of decisions. Ninety-two percent of respondents believed extensive reforms were necessary and 83% that changes made in the previous 5 years had been for the best. However, 56% agreed that there was no clear vision of the reformed system. A small majority (59%) perceived health care reform as having been designed to improve health rather than reduce spending, contrary to a previous hypothesis. Many respondents (76%) thought that boards were legally responsible for things over which they had insufficient control, and 63% perceived that they were too restricted by rules laid down by the provincial government, findings that confirm the expectation of tensions surrounding the division of authority. Respondents with current or former experience as health care providers were less likely than nonprovider respondents to believe that nonphysician health care providers support decisions made by the regional health boards (45% v. 63%, p = 0.02), a result that confirmed the contention that the role of health care providers on the boards would be a source of tension. INTERPRETATION: Members of Saskatchewan district health boards supported the general goals of health care reform and believed that changes already undertaken had been positive. There were few major differences in views between appointed and elected members and between provider and nonprovider members. However, tensions related to authority and representation will require resolution.

Evidence-based nursing Web sites: finding the best resources.

Evidence-based nursing is becoming an increasingly widespread phenomenon in the nursing profession. As the evidence-based nursing movement grows, the Internet/World Wide Web has become a vital information link for keeping pace with current science and medical advancements. This article describes Internet resources currently available to support evidence-based nursing practice, presents practical search methods for locating these resources, and suggests criteria for evaluating the "evidence" available on the Internet. Results of an Internet search for Web sites that met the proposed criteria for support of an evidence-based nursing practice located only three sites. The sites are described and evaluated for their usefulness. The authors demonstrate that although many Internet resources are available to nurses, few sites provide information or evidence supported by valid research.

Nurses' experience of violence in Alberta and British Columbia hospitals.

This study examined responses to a survey on violence in the workplace from a sample of 8,780 registered nurses practising in 210 hospitals in the Canadian provinces of Alberta and British Columbia. Findings relate to the frequency of violence against nurses, reported as the number of times they experienced a violent incident in the workplace. Nearly half (46%) of those surveyed had experienced 1 or more types of violence in the last 5 shifts worked. Frequency varied by type: emotional abuse 38%, threat of assault 19%, physical assault 18%, verbal sexual harassment 7.6%, sexual assault 0.6%. Further, 70% of those who had experienced violence indicated they had not reported it. Patients constituted the main source of all types of violence. The most prevalent type, emotional abuse, was further explored for its possible determinants. This was also the type of violence most evenly distributed among sources (patients, families, co-workers, physicians). Multiple regression modelling using the individual nurse as the unit of analysis showed the significant predictors of emotional abuse to be age, casual job status, quality of care, degree of hospital restructuring, type of unit, relationships among hospital staff, nurse-to-patient ratios, and violence-prevention measures; using the hospital as the unit of analysis the predictors were found to be quality of care, age, relationships with hospital staff, presence of violence-prevention measures, and province. These findings illustrate important differences in models that use the individual and the institution as the unit of analysis. Implications include targeting prevention strategies not only at the nurse but, perhaps more importantly, at the hospital. Overall, the findings suggest that health-care institutions are not always healthy workplaces and may increasingly be stressful and hazardous ones.

The conceptual structure of research utilization.

Despite the fact that the nursing literature is replete with calls to make the practice of nursing research based, little is known about the structure and function of research utilization. The purpose of this study was to explore the conceptual structure of research utilization. Data were collected from a randomly selected sample of 600 registered nurses practicing in western Canada. Using the techniques of structural equation modeling (with LISREL), competing models representing conceptual structures of research utilization were developed and evaluated. In the first model, a simplex style of model, the investigator proposed that a nurse's early responses would influence subsequent responses to the question measuring research utilization, implying a time ordered causal sequence. In the second style of model, a common cause (or factor-like) model, the investigator proposed a stable underlying concept, research utilization, that was relatively insensitive to prompting and time ordering. The simplex style of model failed to reach acceptable indices of fit. The common cause model fit the data well, suggesting that instrumental, conceptual, and persuasive research utilization exist and that a global measure of research utilization may be defensible.

Modeling the individual determinants of research utilization.

Despite more than two decades of investigation, our accumulated knowledge about what influences nurses' use of research is underdeveloped. This study's objectives were to develop and test a series of structural equation models that included individual factors believed to influence research utilization. Estimates of the models were obtained using maximum likelihood estimation. Model fit was assessed by examining chi-square, the adjusted goodness of fit index, and the standardized residuals. Within a simple model that permitted only direct effects and controlled for instrumental, conceptual, and persuasive research utilization, 3 of 26 concepts exerted significant effects on research utilization. These were a positive attitude toward research, belief suspension, and in-services attended. These results support the assertion that our descriptive body of research on the determinants of research utilization is underdeveloped, limiting our ability to design and test effective strategies to increase the use of research findings in nursing practice.

Mapping the research utilization field in nursing.

The recent increase in interest in the field of research utilization, often embedded in the notions of evidence-based practice, presents a rich opportunity to advance the field in nursing. While an extensive literature on the subject exists in nursing, close examination reveals that much of it is opinion and anecdotal literature, and that sustained and programmatic theory building and testing in this field has been sporadic at best. This article maps the field of research utilization, proposing that we focus on major areas of inquiry: scientific, historical, and philosophical foundations, synthesis, determinants, policy, interventions to increase research utilization, and outcomes. In so doing, alternative ways of viewing and conceptualizing this field are possible. In conducting the kinds of studies and supporting the kinds of programs identified in this map, nursing, in collaboration with appropriate partners, can significantly advance the field of research dissemination and utilization studies and practice at many levels in the health system.

Nurse staffing and patient outcomes: evolution of an international study.

Industry-wide health sector reforms in the United States, Canada, and Europe have provided a unique opportunity to examine the effects of hospital restructuring on inpatient nursing care and patient outcomes across an array of settings. Seven interdisciplinary research teams--1 each in Alberta, British Columbia, England, Germany, Ontario, Scotland, and the United States--have formed an international consortium whose aim is to study the effects of such restructuring. Each site has enrolled large numbers of hospitals and nurses to explicate the role that organization of nursing care, a target of hospital restructuring, plays in differential patient outcomes. The study seeks to understand more fully the influence of both nurse staffing and the nursing practice environment on patient outcomes. Discussion of the theoretical foundation, study design, and process of developing the study instruments and measures illustrates the process to date, as well as the feasibility of and opportunities inherent in such an international endeavour.

Will evidence-based nursing practice make practice perfect?

Evidence-based practice, or evidence-based decision-making, is rapidly developing as a growth industry in nursing and the health professions more widely. It has its origins in the work of the British epidemiologist Archie Cochrane and has recently been re-energized in Canada by the National Forum on Health and its call for a culture of evidence-based decision-making. Before we adopt evidence-based nursing (EBN) as a mantra for the 21st century, we should examine its origins and its consequences, and we should probe related concepts, 2 of which are the nature and structure of practice-based knowledge and the nature and structure of evidence generally. Findings of a recent survey of nurses in western Canada are used to illustrate that nurses use a broad range of practice knowledge, much of which is experientially based rather than research-based.

What kind of evidence does qualitative research offer cardiovascular nurses?

In this article I have tried to present a brief overview of qualitative research and to suggest some of the ways in which it may be of use to practitioners. Traditionally, we have not included qualitative studies in our discussion of research utilization. I think this is an unfortunate omission. Qualitative studies have a great deal to offer the practitioner and there are ways in which she or he can make use of them without doing so prematurely and without bringing harm to the client or patient. The required ingredients are twofold. First, from the research side we need scientifically sound studies. Second, from the practice side we need curious and informed consumers-consumers who are willing to take new information into their practice repertoires and let it inform those repertoires. Simple ingredients ... hard to get the cake to rise sometimes, though.

Data sharing in nursing research: advantages and challenges.

The sharing of data between investigators has received little attention in the nursing literature. Among other advantages, data sharing reinforces open scientific inquiry, encourages the development of multiple perspectives, and reduces respondent burden. However, ownership and control of the shared data, preservation of respondents' anonymity, and the costs of data sharing are among the issues that need to be addressed in agreements and contracts involving primary investigators, secondary investigators, and data repositories. The original researcher must spend time and energy to make data sharing possible. It is only when such efforts are acknowledged and rewarded that data sharing is likely to become a norm in the nursing profession. The authors argue that research data should be shared and nurse researchers should seek to have data from all publicly funded projects deposited in accessible data repositories. Nurse researchers need to incorporate plans for data sharing into their research programs and press for the infrastructures required to enable data sharing.

Toward a theory of touch: the touching process and acquiring a touching style.

Methods of grounded theory were used to explore the questions: How do intensive care nurses perceive touch and the process of touching? How do intensive care nurses learn to touch? Data were collected by in-depth interviews with eight experienced intensive care nurses from the same intensive care unit of a large urban Canadian hospital. Findings revealed two substantive processes, the touching process and acquiring a touching style, neither of which has been previously reported. The stages and phases of these processes are described as well as cueing, the core variable. Based on the data analysis, touch was conceptualized as a gestalt with multiple dimensions, suggesting that valid operational definitions of touch must incorporate more than skin-to-skin contact.

Touch: a nursing strategy in the intensive care unit.

In this article findings are reported from a qualitative study that examined touch from the perspective of intensive care (ICU) nurses. In-depth interviews with eight experienced ICU nurses and participant observation were used to collect data. Three distinct kinds of touch were identified, as well as normative patterns of touch among ICU nurses. The findings indicate that an understanding of touch is predicated on knowledge about the structural components of touch and the contextual variables and conditions that determine norms of touching. Touch is described as a multipurpose nursing strategy in the ICU. A need was identified to study a wider range of potential therapeutic and nontherapeutic touch meanings for nurses and patients than has previously been reported.
