Moved by a clinical vignette, the author propose the following question: In patients over 65 with probable diagnosis of acute bronchitis, does the use of antibiotics produce improvement in any clinical outcome?After carrying out a bibliographic search, the evidence published in a recent systematic review is summarized, which concludes that although there are statistically significant benefits in some results of interest, these do not seem to have clinical impact, tak-ing into account the usually self-limited and benign nature of this disease and the possibility of collateral effects related to the treatment. It is important to highlight, however, that the evidence was limited to fully address the elderly population affected by this problem. (AU)
