Abstract:
Bacterial infections are one of the main causes of chronic obstructive pulmonary disease exacerbation, so the use of prophylactic antibiotics, especially macrolides, has been proposed in these patients. However, it is unclear whether antibiotics use is worth the risk and cost. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified five systematic reviews including eight randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded prophylactic antibiotics probably decrease exacerbations in chronic obstructive pulmonary disease, but have no effect on hospitalizations or mortality.
