This guidance is really aimed at GU Medicine – but some useful bits for us. The point of it is that even short interventions can have some impact on people having safer sex.
There is an excellent patient leaflet, which could be used for people you think are at risk.
Generally think about asking about safe sexual practices in adolescents, men who have sex with men, people who’ve had previous STDs or been contacts of STDs and people who have frequent partner changes. If you give out the advice when they consult for something relevant, it is more likely to lead to change!
