丹麥歐登塞大學醫院Camilla H Nejstgaard團隊研究了利益衝突與臨床指南等文件中偏好推薦之間的相關性。2020年12月9日,該研究發表在《英國醫學雜誌》上。
為了調查利益衝突與臨床指南、諮詢委員會報告、意見書和敘述性評論中的偏好推薦之間的相關性,研究組在PubMed、Embase、科學引文索引等大型資料庫中檢索相關文獻,進行了一項系統性審查。
研究組共納入了21項研究,分析了106份臨床指南、1809份諮詢委員會的報告、340份意見書和497篇敘述性評論;以及11項已接收但尚未發布數據的研究。15項研究存在混淆的風險,因為比較的文件可能在利益衝突之外的其他因素上有所不同(例如,針對不同人群使用不同藥物)。
財務利益衝突和臨床指南偏好推薦有關聯的相對風險為1.26,諮詢委員會報告為1.20,意見書為2.62,敘述性評論為1.20。綜合所有四種類型的文件分析支持了這些發現。在一項調查專業興趣的研究中,將放射科醫生作為指南作者與常規推薦乳腺癌篩查有關的相對風險為2.10。
研究結果表明,財務利益衝突與臨床指南、諮詢委員會報告、意見書和敘述性評論中對藥物和設備的偏好推薦有關。

Abstract: Objective To investigate the association between conflicts of interest and favourable recommendations in clinical guidelines, advisory committee reports, opinion pieces, and narrative reviews.
Design Systematic review.
Eligibility criteria Studies that compared the association between conflicts of interest and favourable recommendations of drugs or devices (eg, recommending a drug) in clinical guidelines, advisory committee reports, opinion pieces (eg, editorials), or narrative reviews.
Data sources PubMed, Embase, Cochrane Methodology Register (from inception to February 2020), reference lists, Web of Science, and grey literature.
Data extraction and analysis Two authors independently extracted data and assessed the methodological quality of the studies. Pooled relative risks and 95% confidence intervals were estimated using random effects models (relative risk >1 indicates that documents with conflicts of interest more often had favourable recommendations than documents with no conflicts of interest). Financial and non-financial conflicts of interest were analysed separately, and the four types of documents were analysed separately (preplanned) and combined (post hoc).
Results 21 studies that analysed 106 clinical guidelines, 1809 advisory committee reports, 340 opinion pieces, and 497 narrative reviews were included. Unpublished data were received for 11 studies (eight full datasets and three summary datasets). 15 studies showed risk of confounding because the compared documents could differ in factors other than conflicts of interest (eg, different drugs used for different populations). The relative risk for associations between financial conflicts of interest and favourable recommendations for clinical guidelines was 1.26 (95% confidence interval 0.93 to 1.69; four studies of 86 clinical guidelines), for advisory committee reports was 1.20 (0.99 to 1.45; four studies of 629 advisory committee reports), for opinion pieces was 2.62 (0.91 to 7.55; four studies of 284 opinion pieces), and for narrative reviews was 1.20 (0.97 to 1.49; four studies of 457 narrative reviews). An analysis of all four types of documents combined supported these findings (1.26, 1.09 to 1.44). In one study that investigated specialty interests, the association between including radiologists as authors of guidelines and recommending routine breast cancer was: relative risk 2.10, 95% confidence interval 0.92 to 4.77; 12 clinical guidelines).
Conclusions We interpret our findings to indicate that financial conflicts of interest are associated with favourable recommendations of drugs and devices in clinical guidelines, advisory committee reports, opinion pieces, and narrative reviews. Limitations of this review were risk of confounding in the included studies and the statistical imprecision of individual analyses of each document type. It is not certain whether non-financial conflicts of interest influence recommendations.
