The aim of this online cross-sectional study is to identify the sources of scientific information used by Brazilian dentists in clinical decision-making and the barriers that they perceive as important to the incorporation of scientific evidence into clinical practice. A pretested questionnaire created in Google Forms which was made available to participants through links sent by e-mail or shared on Facebook® and Instagram® was used to collect the data between October 2018 and May 2019. Only dentists who were involved in direct or indirect care of patients (i.e. clinicians who performed dental procedures or dental educators who participated in the clinical training of graduate or postgraduate dental students) were asked to complete the questionnaire. The sample was comprised of 528 dentists (the response rate from the alumni database was 6.9%); their mean age was 45.2 years (±12.5) and 30.9% had an academic position. The majority were women (68.0%) and lived in Southern or Southeastern Brazil (96.0%). The sources of scientific information more frequently used by them in clinical decision-making were clinical guidelines (65.1%; 95% CI: 60.9, 69.2), scientific articles (56.8%; 95%CI: 52.5, 61.1) and bibliographic databases (48.3%; 95% CI: 43.9, 52.6). The information resource less frequently used was social media. The most important barriers to the clinical use of scientific evidence were: difficulty in determining whether scientific contents found on the Internet were reliable or not (41.8%; 95% CI: 37.6, 46.2), high cost of access to scientific papers (37.7%; 95% CI: 33.5, 41.9), and lack of time for reading scientific articles (32.4%; 95% CI: 28.4, 36.6). Although Brazilian dentists show a positive attitude towards obtaining scientific evidence from reliable sources, there still remain important barriers to the translation of evidence into practice. This can have significant implications for quality of care and should be further investigated.
本在线横断面研究的目的是确定巴西牙医在临床决策中使用的科学信息来源，以及他们认为对将科学证据纳入临床实践有重要影响的障碍。研究使用了一个预先测试的谷歌表单调查问卷，通过电子邮件发送的链接或在 Facebook®和 Instagram®上共享的链接将其提供给参与者，数据收集时间为 2018 年 10 月至 2019 年 5 月。只有直接或间接参与患者护理的牙医（即进行牙科手术的临床医生或参与研究生或研究生牙科学生临床培训的牙科教育者）被要求完成问卷。样本由 528 名牙医组成（校友数据库的回复率为 6.9%）；他们的平均年龄为 45.2 岁（±12.5），30.9% 具有学术职位。大多数为女性（68.0%），居住在巴西南部或东南部（96.0%）。他们在临床决策中更频繁使用的科学信息来源是临床指南（65.1%；95%CI：60.9，69.2）、科学文章（56.8%；95%CI：52.5，61.1）和书目数据库（48.3%；95%CI：43.9，52.6）。使用较少的信息资源是社交媒体。将科学证据应用于临床的最重要障碍是：难以确定在互联网上找到的科学内容是否可靠（41.8%；95%CI：37.6，46.2），获取科学论文的成本高（37.7%；95%CI：33.5，41.9），以及缺乏阅读科学文章的时间（32.4%；95%CI：28.4，36.6）。尽管巴西牙医对从可靠来源获取科学证据表现出积极态度，但将证据转化为实践仍存在重要障碍。这可能对护理质量产生重大影响，应进一步调查。
