Evidence-based practice (EBP) is essential to the improvement of patient outcomes and the quality of care. Nurses' use of evidence in practice, however, remains limited. Assessing nurses' readiness for EBP where it is not as prominent as in countries leading EBP research was of particular interest.
To determine Icelandic registered nurses' (RNs') ability to provide care based on evidence as measured by their beliefs, perception of skills, and access to resources associated with EBP.
A descriptive survey was used in which a random sample of 540 Icelandic RNs completed the translated and modified version of the Information Literacy for Evidence-Based Nursing Practice and the translated EBP Beliefs Scale. Descriptive statistics, correlations, chi-square tests, t tests and one-way ANOVAs were used to analyze the data.
Participants strongly believed in the value of EBP for patient care, but were less confident regarding their own knowledge and skills needed for EBP. Most (82%) of the respondents (i.e., RNs) turned to peers when in need of information, rather than peer-reviewed resources. Although over half of the RNs (54%) had received instructions in the use of electronic databases, only a third indicated success in using them. They considered "lack of search skills" as the primary barrier to use of research in practice. Using research findings in practice was associated with positive EBP beliefs, familiarity with EBP and other EBP-related activities. Clinical RNs were found to be at a disadvantage when it came to access to EBP-related resources and participated less frequently in EBP-related activities other than using research in practice.
Icelandic RNs' beliefs regarding EBP are similar to those of RNs in other countries. Their access to EBP resources is generally good, but they lack the skills and knowledge needed for EBP. Strategies aimed at changing the organizational and practice context need to be developed.
循证实践（EBP）对于改善患者结局和护理质量至关重要。然而，护士在实践中应用证据的情况仍然有限。在循证实践研究领先的国家之外，评估护士在 EBP 方面的准备情况尤其具有意义。
通过评估冰岛注册护士（RN）在 EBP 方面的信念、技能感知和与 EBP 相关资源的获取情况，确定他们提供循证护理的能力。
采用描述性调查研究，对 540 名冰岛 RN 进行随机抽样，采用经过翻译和修改的《循证护理实践信息素养》和《EBP 信念量表》对他们进行评估。使用描述性统计、相关性、卡方检验、t 检验和单因素方差分析来分析数据。
参与者强烈相信 EBP 对患者护理的价值，但对自己进行 EBP 所需的知识和技能缺乏信心。大多数（82%）的受访者（即 RN）在需要信息时求助于同行，而不是同行评审资源。尽管超过一半的 RN（54%）接受过使用电子数据库的指导，但只有三分之一的人表示成功使用过。他们认为“缺乏搜索技能”是在实践中使用研究的主要障碍。在实践中使用研究结果与积极的 EBP 信念、对 EBP 的熟悉程度以及其他 EBP 相关活动有关。临床 RN 在获取 EBP 相关资源方面处于劣势，除了在实践中使用研究外，他们参与其他 EBP 相关活动的频率也较低。
冰岛 RN 对 EBP 的信念与其他国家的 RN 相似。他们获取 EBP 资源的情况总体良好，但缺乏进行 EBP 所需的技能和知识。需要制定旨在改变组织和实践环境的策略。
