Adherence to Hydroxychloroquine Dosing Guidelines by Rheumatologists

Approximately one half of all patients started on HCQ by NorthShore rheumatologists received doses in excess of the recommended maximum, and slightly more than one-half of all patients currently on treatment continue to receive excess doses. Our data suggest that the publication of the consensus guidelines in 2011 had no appreciable effect on HCQ dosing and that transitioning to the 2016 dosing modification is unlikely to change this outcome unless additional steps are taken to improve adherence.
