"Words matter in science that matters. Far too often, however, the words in medical literature are chosen and arranged without enough care. This leads to confusing, jargon-filled writing that is difficult to read, even for medical researchers. Not only is careless writing a barrier to publication, it makes it more difficult for peers to understand and build on other researchers’ work. Poor communication limits the impact of medical research, so clinicians and patients ultimately suffer as well. Vague and ambiguous clinical practice guidelines, for example, have been linked to medical errors and inconsistent interpretation. … Writing about complex medical research in plain language is challenging. Technical terms, acronyms and jargon, although used too frequently, cannot be avoided entirely. But the benefits — improved knowledge translation, less research waste — are too great for needlessly complicated writing to be accepted as inevitable. Medical educators, academic institutions and health care researchers have a duty to improve the quality of written communication to extend the reach of useful medical knowledge."
