Background:

Popularization of systematic reviews has been met with controversy because of concerns that the primary literature for certain topics may not be suited for systematic review and meta-analysis.

Purpose:

To assess the rate of publication of systematic reviews based on their level of evidence (LOE) in influential orthopaedic sports medicine journals and commonly studied topics in sports medicine.

Study Design:

Systematic review.

Methods:

An electronic search was performed using the PubMed database of studies published from January 2010 to December 2020. The advanced search function was used to identify systematic reviews from the Journal of Shoulder and Elbow Surgery (JSES), American Journal of Sports Medicine (AJSM), Arthroscopy, British Journal of Sports Medicine (BJSM), Journal of Bone and Joint Surgery–American Volume (JBJS), and Sports Medicine (SM Auckland), as well as reviews of the most common areas of sports medicine research, including rotator cuff repair (RCR), shoulder instability (SI), anterior cruciate ligament reconstruction (ACLR), and meniscal repair. The LOE was assigned to each included study according to the Oxford Centre for Evidence-Based Medicine. Studies were grouped as LOE 1-2, LOE 3-5, and nonclinical systematic reviews. A negative binomial regression was used to determine the changes in publication rate over time.

Results:

A total of 2162 systematic reviews were included in this study. From 2010 to 2020, the rate of publication of LOE 3-5 systematic reviews increased significantly among most of the surveyed journals (AJSM, P < .0001; Arthroscopy, P = .01; BJSM, P < .0001; JSES, P < .0001; SM Auckland, P < .0001), with the exception of JBJS (P = .57). The rate of publication of LOE 1-2 systematic reviews increased in AJSM (P < .0001), Arthroscopy (P = .02), BJSM (P < .0001), and SM Auckland (P < .0001); however, no significant changes were seen in JBJS (P = .08) or JSES (P = .15). The publication rate of LOE 3-5 systematic reviews increased for all sports medicine topics surveyed (meniscal repair, P < .0001; RCR, P < .0001; SI, P < .0001; ACLR, P < .0001). However, the publication rate of LOE 1-2 studies only increased for RCR (P = .0003) and ACLR (P < .0001).

Conclusion:

The rate of publication of LOE 3-5 systematic reviews exponentially increased in orthopaedic sports medicine journals over the past decade, outpacing the publication rate of LOE 1-2 systematic reviews.

2010-2020 年运动医学系统评价证据水平趋势：系统评价和荟萃分析

背景：

由于担心某些主题的主要文献可能不适合系统评价和荟萃分析，系统评价的普及遇到了争议。

目的：

根据系统评价在有影响力的骨科运动医学期刊中的证据水平 (LOE) 和运动医学中普遍研究的主题来评估系统评价的发表率。

学习规划：

系统评价。

方法：

使用 PubMed 2010 年 1 月至 2020 年 12 月发表的研究数据库进行电子搜索。高级搜索功能用于识别来自肩肘外科杂志( JSES )、美国运动医学杂志( AJSM )、关节镜检查、英国运动医学杂志( BJSM )、骨与关节外科杂志-美国卷( JBJS ) 和运动医学( SM 奥克兰))，以及对运动医学研究最常见领域的评论，包括肩袖修复 (RCR)、肩部不稳定 (SI)、前交叉韧带重建 (ACLR) 和半月板修复。根据牛津循证医学中心，将 LOE 分配给每项纳入的研究。研究分为 LOE 1-2、LOE 3-5 和非临床系统评价。负二项式回归用于确定发表率随时间的变化。

结果：

本研究共纳入 2162 篇系统评价。从 2010 年到 2020 年，LOE 3-5 系统评价的发表率在大多数接受调查的期刊中显着增加（AJSM，P < .0001；关节镜检查，P = .01；BJSM，P < .0001；JSES，P < .0001；SM 奥克兰，P < .0001)，JBJS 除外( P = .57)。LOE 1-2 系统评价的发表率在AJSM ( P < .0001)、关节镜检查( P= .02)、BJSM ( P < .0001) 和SM 奥克兰( P < .0001)；然而，在JBJS ( P = .08) 或JSES ( P = .15)中没有发现显着变化。对于所有调查的运动医学主题，LOE 3-5 系统评价的发表率都有所提高（半月板修复，P < .0001；RCR，P < .0001；SI，P < .0001；ACLR，P < .0001）。然而，LOE 1-2 研究的发表率仅增加了 RCR ( P = .0003) 和 ACLR ( P < .0001)。

结论：

在过去十年中，骨科运动医学期刊中 LOE 3-5 系统评价的发表率呈指数增长，超过了 LOE 1-2 系统评价的发表率。
