Fundamental flaws in the design and reporting of research outcomes can undermine evidence-based medicine, impede patient-centred care, cause harm to patients, and result in a waste of research dollars. Our 3-year multinational project engages with patients, caregivers, clinicians, researchers and policy makers, to establish core outcomes in haemodialysis. This will ensure that patient-centred outcomes are consistently measured and reported in haemodialysis trials and other forms of research.
