I was part of an evidence mapping project that sought to do this in neurotrauma. "The Global Evidence Mapping Initiative: scoping research in broad topic areas" http://www.biomedcentral.com/1471-2288/11/92
Are there any established methods for identifying gaps in the research evidence? Can critical appraisal do this? I have seen this claim made in several articles but nowhere is this backed up by a reference.
