They included a phone survey with 34 major international research initiatives, a series of workshops with experts, and case studies applying the proposed guidelines.Results: A wide range of projects use retrospective harmonization to support their research activities but even when appropriate approaches are used, the terminologies, procedures, technologies and methods adopted vary markedly. However, despite its widespread practice, no formalized/systematic guidelines exist to ensure high quality retrospective data harmonization.Methods: To better understand real-world harmonization practices and facilitate development of formal guidelines, three interrelated initiatives were undertaken between 20. This can be seen as a key step towards implementing guiding principles analogous to those that are well recognised as being essential in securing the foundational underpinning of systematic reviews and the meta-analysis of clinical trials.Ībstract = "Background: It is widely accepted and acknowledged that data harmonization is crucial: in its absence, the co-analysis of major tranches of high quality extant data is liable to inefficiency or error. ![]() The generic guidelines outlined in this article delineate the essentials required and describe an interdependent step-by-step approach to harmonization: 0) define the research question, objectives and protocol 1) assemble pre-existing knowledge and select studies 2) define targeted variables and evaluate harmonization potential 3) process data 4) estimate quality of the harmonized dataset(s) generated and 5) disseminate and preserve final harmonization products.Ĭonclusions: This manuscript provides guidelines aiming to encourage rigorous and effective approaches to harmonization which are comprehensively and transparently documented and straightforward to interpret and implement.
