Developing, delivering, and evaluating cancer nursing services: searching for a United Kingdom evidence base for practice.

The drive toward evidence-based healthcare aims to promote effectiveness and thereby improve quality. The challenge for cancer nursing is to continually evaluate what it does, retaining effective interventions and working to develop new ones and refine those interventions that require improvement, thereby enhancing both practice and patient outcomes. The aim of the project was to assimilate an evidence base to support the development, delivery, and evaluation of cancer nursing services in the United Kingdom. It was believed that determining the extent of the current United Kingdom evidence base through a review of the literature and current and recent research endeavors would allow for comparison with current priorities and facilitate informed strategic planning regarding the process of research commissioning. A rigorous, explicit, and thorough literature review was undertaken of all United Kingdom literature pertaining to cancer nursing and related issues published between 1980 and 2000. Fourteen individual databases were searched using specific keywords, thesaurus terms, and additional search terms. Data were extracted from each individual publication and stored in a purpose-designed database. Current and recent United Kingdom cancer nursing research projects were identified through a mailed survey questionnaire sent to people and organizations involved in cancer-related research. Research projects were categorized according to Royal College of Nursing research priority themes: Care and Caring Practices, Healthcare Environment, Organization and Management of Care, and Healthcare Workforce. Four-hundred forty-six pieces of literature were considered appropriate for inclusion in the review. Two-hundred sixty-four pieces of evidence were included in the Care and Caring Practices theme, which also had the greatest number of current and recent research projects (48%, n = 50). The Healthcare Environment theme included 80 pieces of evidence but only 3% (n = 3) of the current and recent research projects. Thirty-two percent (n = 33) of the current/recent research projects fell into the third theme of Organization and Management of Care, which contained a total of 104 pieces of evidence. The final theme, Healthcare Workforce, included 17% (n = 18) of the current and recent research projects, and the literature review incorporated 49 pieces of evidence in this theme. A number of recommendations have been drawn, which focus on methodological challenges, research considerations, and gaps in the evidence base. The drive toward evidence-based practice is essential for cancer nurses to establish who they are, what they do, and what effect they have on patient outcomes. Currently, although the United Kingdom evidence base for practice is vast, it frequently lacks depth. Although evaluating national evidence for practice is valuable, a more global approach to evidence synthesis is required. Through such endeavors, cancer nurses should realize their potential, support the strategic development of cancer nursing research, and so generate an evidence base that supports their unique contribution to patient outcomes.
