To describe the quality and methods of systematic reviews of physiotherapy interventions, compare Cochrane and non-Cochrane reviews, and establish the interrater reliability of the Overview Quality Assessment Questionnaire (OQAQ) quality assessment tool.
A survey of 200 published systematic reviews was done. Two independent raters assessed the search strategy, assessment of trial quality, outcomes, pooling, conclusions, and overall quality (OQAQ). The study was carried out in the University research center.
In these reviews, the five most common databases searched were MEDLINE, EMBASE, Cochrane Library, CINAHL, and Cochrane Review Group Registers. The Cochrane allocation concealment system and Jadad Scale were most frequently used to assess trial quality. Cochrane reviews searched more databases and were more likely to assess trial quality, report dichotomous outcomes for individual trials, and conduct a meta-analysis than non-Cochrane reviews. Non-Cochrane reviews were more likely to conclude that there was a beneficial effect of treatment. Cochrane reviews were of higher quality than non-Cochrane reviews. There has been an increase in the quality of systematic reviews over time. The OQAQ has fair to good interrater reliability.
The quality of systematic reviews in physiotherapy is improving, and the use of Cochrane Collaboration procedures appears to improve the methods and quality.
描述物理治疗干预系统评价的质量和方法，比较Cochrane系统评价和非Cochrane系统评价，并确定综述质量评估问卷（OQAQ）质量评估工具的评分者间信度。
对200篇已发表的系统评价进行了调查。两名独立评分者评估了检索策略、试验质量评估、结果、合并分析、结论和整体质量（OQAQ）。该研究在大学研究中心进行。
在这些系统评价中，最常检索的五个数据库是MEDLINE、EMBASE、Cochrane图书馆、CINAHL和Cochrane系统评价组注册库。Cochrane分配隐藏系统和Jadad量表最常用于评估试验质量。与非Cochrane系统评价相比，Cochrane系统评价检索了更多数据库，更有可能评估试验质量、报告单个试验的二分法结果并进行荟萃分析。非Cochrane系统评价更有可能得出治疗有有益效果的结论。Cochrane系统评价的质量高于非Cochrane系统评价。随着时间的推移，系统评价的质量有所提高。OQAQ具有中等至良好的评分者间信度。
物理治疗系统评价的质量正在提高，采用Cochrane协作程序似乎能改善方法和质量。
