BRISQ - Biospecimen Reporting for Improved Study Quality

In 2011, the NIH released a set of recommendations for the publication of studies using human biospecimens1. These guidelines are applicable to animal biospecimens as well. According to the authors, "biospecimens are subject to a number of different collection, processing, and storage factors that can significantly alter their molecular composition and consistency. These biospecimen preanalytical factors, in turn, influence experimental outcomes and the ability to reproduce scientific results. Currently, the extent and type of information specific to the biospecimen preanalytical conditions reported in scientific publications and regulatory submissions varies widely. To improve the quality of research utilizing human tissues it is critical that information regarding the handling of biospecimens be reported in a thorough, accurate, and standardized manner. The Biospecimen Reporting for Improved Study Quality (BRISQ) recommendations outlined herein are intended to apply to any study in which Biospecimens are used. The purpose of reporting these details is to supply others, from researchers to regulators, with more consistent and standardized information to better evaluate, interpret, compare, and reproduce the experimental results. The BRISQ guidelines are proposed as an important and timely resource tool to strengthen communication and publications around biospecimen-related research and help reassure contributors and the advocacy community that the contributions are valued and respected".

Similar guidelines have been published to address the need to integrate the 3Rs principles of animal studies and make systematic reviews feasible2.The recommended parameters cover a broader spectrum as BRISQ and go beyond the biospecimen, including information about the study design, the methods used, the description of results, etc. This approach is more suited for the final reporting of the study.
