Summary
Assessing the quality of systematic reviews (SRs) is crucial for evidence-based healthcare. This study found diverse methods are used, with PRISMA, OQAQ, and AMSTAR being the most common tools for methodological and reporting quality assessment.
Area of Science:
- Evidence-based healthcare
- Systematic review methodology
- Research quality assessment
Background:
- Methodological quality and reporting completeness of systematic reviews (SRs) are vital for effective evidence-based healthcare and reducing research waste.
- Existing methods for appraising SRs are known, but their application and potential gaps in best-practice guidance remain unclear.
- This study aimed to identify reports assessing the methodological quality (MQ) and/or reporting quality (RQ) of SRs, analyzing their characteristics and quality assessment approaches over time.
Purpose of the Study:
- To identify and characterize reports that assess the methodological and/or reporting quality of systematic reviews.
- To analyze the trends and approaches used in assessing the quality of systematic reviews over time.
- To understand the landscape of quality assessment tools and guidelines employed in systematic review research.
Main Methods:
- A comprehensive literature search was conducted in Cochrane Library, MEDLINE, and EMBASE from January 1990 to October 2014.
- Reports assessing the MQ and/or RQ of a cohort of ten or more SRs of interventions were included after independent screening by two reviewers.
- Data on the number, characteristics, and quality assessment approaches were extracted and reported as frequencies and percentages.
Main Results:
- Out of 20,765 unique records, 76 reports met the inclusion criteria.
- Eight established approaches (reporting guidelines like PRISMA, QUOROM; quality assessment tools like AMSTAR, OQAQ, Mulrow, Sacks, GRADE) were used in 80% of reports.
- PRISMA, OQAQ, and AMSTAR were the most frequently utilized published tools for assessing MQ or RQ.
Conclusions:
- The methods for assessing the quality of SRs are varied, with no single approach achieving universal acceptance.
- AMSTAR, OQAQ, and PRISMA are the most commonly employed tools for quality assessment in systematic reviews.
- Authors conducting methodological studies are encouraged to carefully select appropriate tools and guidelines for assessing both the methodological and reporting quality of SRs as new resources emerge.

01:15Systematic Error: Methodological and Sampling Errors
11.2K
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

01:19Quality Assurance
3.7K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
