Antibiotic prescription for endodontic infections among Italian dental practitioners: what is the extent of over-prescription?

The dataset was used in a cross-sectional study primarily aimed to to investigate the pattern of antibiotic prescription for prophylaxis purposes among Italian DPs.
From April to October 2019, a nationwide cross-sectional study was conducted in a representative sample of the Italian general and specialist DPs. The information is collected through a mixed technique, which uses an online questionnaire that is filled in by respondents, a direct telephone interview with the questionnaire administered by an interviewer, and a self-administered paper questionnaire.
A structured questionnaire was used, comprising of four sections: (1) an introductory section presenting study aims and motivation at the end of which DPs could give their written consent in joining the study; (2) a socio-demographic data collection section; (3) the main research section about practices regarding prophylactic antibiotic prescriptions; (4) and sources of information used to update knowledge on antibiotic use in dental practices. Bivariate (t-tests, chi-square and Fisher exact test) and multivariate analyses were conducted to examine the potential association with the DP correct prescription practice. Moreover, a logistic regression model was used to estimate the odds of correct prescription practice depending on the invasive dental procedures and the presence of indication or not. The interaction between the two factors was also investigated.
563 DPs answered the general questionnaire (response rate 52.6%).

该数据集被应用于一项横断面研究，主要旨在探究意大利牙科医生在预防目的下的抗生素处方模式。自2019年4月至10月，一项全国性的横断面研究在意大利普通及专科牙科医生代表性样本中进行。数据收集通过混合技术完成，包括由受访者填写的在线问卷、由访谈员执行的直接电话访谈以及自行填写的纸质问卷。问卷结构严谨，分为四个部分：（1）介绍性部分，阐述研究目的与动机，并在末尾允许牙科医生签署书面同意加入研究；（2）社会人口统计学数据收集部分；（3）关于预防性抗生素处方实践的主要研究部分；（4）以及用于更新牙科实践中抗生素使用知识的资料来源。通过双变量分析（t检验、卡方检验和Fisher精确检验）以及多元分析，考察了与牙科医生正确处方实践潜在关联的可能性。此外，采用逻辑回归模型估算根据侵入性牙科手术及是否存在适应症的正确处方实践的概率，并探究了这两个因素之间的交互作用。共有563位牙科医生回答了通用问卷（响应率为52.6%）。
