To assess knowledge, attitudes, and practices on evidence-based medicine (EBM) among doctors in selected hospitals in Sri Lanka.
A cross-sectional descriptive study was conducted among 315 doctors in five government hospitals in Sri Lanka between December 2007 and January 2008. A pre-tested self-administered questionnaire was used to gather information on knowledge, attitudes, and practices.
Of the 407 invited, 315 doctors participated, among whom, 87% (271) had heard the term EBM, 30% (n= 94) were aware of the Cochrane Library, and 8.5% (n= 27) were current users of it. Forty-seven per cent (n= 148) claimed to understand the terms systematic review and 37% (n= 115) meta-analysis. Twenty-four per cent (n= 77) had been exposed to some form of EBM training. All three components of EBM were known by 18% (n= 56) of participants. Attitudes toward EBM were positive among 76% (n= 239), 80% (n= 251) believed the practice of EBM would lead to improved patient care, and 77% (n= 243) considered EBM to be fundamental to professional practice. Just 3% (n= 13) considered it unimportant. EBM was used in clinical practice by 54% (n= 169) of participants. Thirty-six per cent (n= 114) referred to EBM sources when relevant. Available clinical guidelines were referred to by 56% (n= 176), and 34% (n= 107) thought that available guidelines provide sufficient support for the practice of EBM. The main barriers to practicing EBM were insufficient resources, overwork, lack of exposure to EBM, and lack of time and lack of endorsement of the need to practice EBM.
Knowledge and practices of EBM among Sri Lanka doctors were poor. However, attitudes toward EBM were relatively good.
评估斯里兰卡选定医院医生对循证医学（EBM）的知识、态度和实践情况。
2007 年 12 月至 2008 年 1 月期间，在斯里兰卡的五家政府医院中对 315 名医生进行了横断面描述性研究。使用预先测试的自我管理问卷收集有关知识、态度和实践的信息。
在受邀的 407 名医生中，有 315 名医生参与了研究，其中 87%（271 名）听说过 EBM 一词，30%（n=94）知道 Cochrane 图书馆，8.5%（n=27）正在使用它。47%（n=148）声称理解系统评价这一术语，37%（n=115）理解荟萃分析。24%（n=77）接受过某种形式的 EBM 培训。所有三个 EBM 组成部分都为 18%（n=56）的参与者所熟知。76%（n=239）对 EBM 的态度为积极，80%（n=251）认为实践 EBM 将改善患者护理，77%（n=243）认为 EBM 是专业实践的基础。只有 3%（n=13）认为它不重要。54%（n=169）的参与者在临床实践中使用 EBM。36%（n=114）在相关时会参考 EBM 来源。56%（n=176）参考了可用的临床指南，34%（n=107）认为可用指南为 EBM 实践提供了足够的支持。实践 EBM 的主要障碍是资源不足、工作量过大、缺乏对 EBM 的接触以及缺乏时间和对实践 EBM 的必要性的认可。
斯里兰卡医生的 EBM 知识和实践情况较差。然而，他们对 EBM 的态度相对较好。
