Background: Public health nursing is constantly evolving; the profession must adjust to new focus areas, new professional demands, new tasks and more responsibilities.Objectives: The study's objectives were to identify 1) the sources of knowledge that public health nurses use in practice, 2) what skills enable public health nurses to nd and assess research and national guidelines, 3) what barriers public health nurses encounter as they endeavour to nd and assess research and national guidelines, and 4) in uences that impact on their skills in assessing research-based knowledge.Method: This is a cross-sectional study which involved 708 public health nurses completing an online questionnaire. We used statistical analyses to investigate their use of sources of knowledge and the factors that may in uence their skills in assessing research-based knowledge.
PEER-REVIEWED RESEARCH
AuthorsResults: National guidelines, knowledge acquired while training as a public health nurse, personal experience and guidelines issued by local authorities were the most commonly used sources of knowledge. The most signi cant barriers reported were a shortage of time to nd research, and the challenge of understanding articles written in English. The public health nurses considered that they were generally adept at nding and assessing national guidelines, but that they were less pro cient at assessing research-based knowledge. The odds were signi cantly greater that public health nurses with a Master's degree, and public health nurses in fulltime employment, would consider themselves adept at assessing research.
Conclusion:National guidelines constitute the source of knowledge most frequently used by public health nurses. In order to implement evidence-based professional practice, public health nurses must be pro cient at assessing the recommendations set out in national guidelines in combination with other sources of knowledge. A future national competence and development centre for services provided at community and school health care centres may come to play an important role in implementing national guidelines and safeguarding the quality of procedures issued by local authorities.The general population's access to research is ever-increasing. Public health nurses and other nurses must therefore be prepared to answer questions and to discuss findings from research. In line with the requirements for safety and high standards, the objective set out in the consultation draft of the new national professional guidelines for community and school health care centres is to offer health promotional and preventive services (1).Evidence-based practice involves making decisions in a professional capacity based on a combination of systematically obtained research-based knowledge, evidence-based knowledge and the patient's wishes and needs in the given situation (2-4). It is an important principle in evidence-based practice to search for research summaries and evidence-based reference works and guidelines before looking for single studies (5), as sh...
