9 – Compliance with ethical standards in the reporting of donor sources and ethics review in peer-reviewed publications involving organ transplantation in China: a scoping review

Rogers et al’s scoping review on published articles that involved organ transplantation was the centre of many discussions regarding peer-review and ethics in scientific and medical publishing. The scoping review investigated whether research papers that involved organ transplantation in China followed international professional standards that aim to exclude unethical research practices. Such practices included research conducted without IRB approval or consent from donors and the use of biological material from executed prisoners. Rogers et al found that 92.5% of the studies included in their analysis did not report whether organs were sourced from executed prisoners, and that another 99% failed to disclose whether consent from the donors was obtained. The findings of this article quickly caught the attention of several news outlets and scientific journals and prompted numerous investigations into the published articles. As a result, many changes to editorial processes–and some retractions–have been implemented across several journal publishers. graph
