The MD or PhD by Published Work is a degree award for an established researcher who has already published significant research in their discipline. The published work must be peer reviewed (for example in books, journal articles, and research reports).
Your portfolio of published work must form a coherent body of work that constitutes a significant contribution to knowledge in a given area in medicine or medical science.
Your works should be published in high calibre peer review journals or by established publishers in your academic or clinical discipline. The journal/publisher should have a good academic standing. All the publications must have been published physically or electronically, in the public domain.
The number of publications is not as important as the quality of scientific inquiry they represent, their academic standing, and their contribution to the field of study.
Your portfolio of work should resemble a conventional MD or PhD thesis. As an indicative guide, the maximum word limit for a conventional MD and PhD thesis is 80,000 words. There is no lower word limit.
