Scientific evidence in medicine is based on data generated from research. Recently, the number of scientifically active physicians has decreased, which has led to the development of the Clinician Scientist Programs. To better structure and focus the research of young physicians, we aimed to investigate the impact of collaborations and other factors on the quality and output of scientific publications.
The abstracts of three annual congresses of the German Society of Urology were systematically analysed regarding content, collaborations, and study design. Full-text publications and journals were identified through a MEDLINE® search. Impact factors (IFs) were identified using Journal Citation Reports™. To identify factors which predict publication and IFs, χ and Wilcoxon rank-sum tests were used. Uni- and multivariable logistic regression analyses were performed to assess the best model for publication success for an abstract as well as the achievement of a high IF.
1,074 abstracts were reviewed. The publication rate of subsequent peer-reviewed full-text publications was 52.5%. Collaborations with at least one institution (odds ratio (OR) 2.02, 95% confidence interval (CI) 1.48-2.76, p <0.0001), statistical analysis (OR 1.92, 95% CI 1.41-2.60, p <0.0001), study design (prospective vs. retrospective: OR 1.43, 95% CI 1.06-1.93, p=0.021), and national collaborations (OR 1.43, 95% CI 1.04-1.98, p=0.029) increased the likelihood of publication in a peer-reviewed journal in a multivariable logistic regression analysis. Experimental design (OR 2.77, 95% CI 1.32-5.84, p=0.007), international collaborations (OR 2.26, 95% CI 1.23-4.15, p=0.009), oncologic topics (OR 1.94, 95% CI 1.23-3.07, p=0.005), prostate disease (OR 1.75, 95% CI 1.08-2.84, p=0.023), and statistical analysis (OR 1.68, 95% CI 1.06-2.64, p=0.026) were associated with a higher IF.
Abstracts resulting from collaborative research projects had a higher likelihood of subsequent full-text publication and a higher IF. More full-text publications were reported when abstracts included a statistical analysis. Hence, intensive networking (e. g. at congresses and workshops) of researching physicians as well as statistical/biometrical classes could be key factors to improve academic success.
医学中的科学证据基于研究产生的数据。最近,积极从事科研的医生数量有所减少,这促使了临床科学家项目的发展。为了更好地构建和聚焦年轻医生的研究,我们旨在调查合作及其他因素对科学出版物质量和产出的影响。
对德国泌尿外科学会三次年度大会的摘要进行了关于内容、合作和研究设计的系统分析。通过医学文献数据库(MEDLINE®)检索确定全文出版物和期刊。使用期刊引证报告(Journal Citation Reports™)确定影响因子(IFs)。为了确定预测出版物和影响因子的因素,使用了χ检验和威尔科克森秩和检验。进行单变量和多变量逻辑回归分析,以评估摘要发表成功以及获得高影响因子的最佳模型。
共审查了1074篇摘要。后续同行评审全文出版物的发表率为52.5%。与至少一个机构合作(优势比(OR)2.02,95%置信区间(CI)1.48 - 2.76,p <0.0001)、统计分析(OR 1.92,95% CI 1.41 - 2.60,p <0.0001)、研究设计(前瞻性与回顾性:OR 1.43,95% CI 1.06 - 1.93,p = 0.021)以及国内合作(OR 1.43,95% CI 1.04 - 1.98,p = 0.029)在多变量逻辑回归分析中增加了在同行评审期刊上发表的可能性。实验设计(OR 2.77,95% CI 1.32 - 5.84,p = 0.007)、国际合作(OR 2.26,95% CI 1.23 - 4.15,p = 0.0)、肿瘤学主题(OR 1.94,95% CI 1.23 - 3.07,p = 0.005)、前列腺疾病(OR 1.75,95% CI 1.08 - 2.84,p = 0.023)以及统计分析(OR 1.68,95% CI 1.06 - 2.64,p = 0.026)与较高的影响因子相关。
合作研究项目产生的摘要后续全文发表的可能性更高,且影响因子更高。当摘要包含统计分析时,报告的全文出版物更多。因此,研究医生的密集网络交流(如在大会和研讨会上)以及统计/生物统计学课程可能是提高学术成就的关键因素。
