Learning from guidelines on the sexual healthcare of men who have sex with men.

The British Association for Sexual Health and HIV (BASHH) United Kingdom national guideline on the sexual health care of men who have sex with men (MSM) was published in electronic format in this journal in 2018. In common with other BASHH guidelines, the document fulfils the dual role of scrutinising and evaluating the available evidence according to the accredited Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, as well as the often more challenging job of codifying and summarising expert opinion in areas where the evidence base is incomplete or lacking. In addition to the learning gained from developing the recommendations included in the final document, further benefit was derived from the process through a number of learning and development actions for the writing group and through this the MSM special interest group and the wider sexual health community.
