RT Journal Article SR Electronic T1 BTS guideline on long-term macrolides in adults with respiratory disease: not quite a panacea JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 405 OP 406 DO 10.1136/thoraxjnl-2019-214039 VO 75 IS 5 A1 David Smith YR 2020 UL http://thorax.bmj.com/content/75/5/405.abstract AB The British Thoracic Society (BTS) guideline on the use of long-term macrolides in adults with respiratory disease has been published. It indicates where there is evidence to support the use of long-term low-dose macrolides and where there is not. It discusses the potential benefits of such therapy for patients and also describes the potential risks to individuals and wider populations. It seeks to provide a pragmatic approach for clinicians considering long-term macrolide therapy for their patients. This guideline has also acted as a learning exercise for the BTS in introducing the Grading of Recommendations Assessment, Development and Evaluation approach to guideline development, which will be used going forwards.
