Improvement in treat-to-target (T2T) remained relatively stable over a post-intervention period in a recent study that evaluated a second 9 months (phase II), where researchers examined the maintenance of response in phase I and predictors of greater improvement in T2T adherence. They recruited patients (n=636) from 11 rheumatology sites and randomized them to either receive the learning collaborative during phase I or to a wait‐list control group that received the learning collaborative intervention during phase II. The outcome was change in T2T implementation score (0–100, where 100 = best) from pre‐ to post-intervention. They found:

• At baseline, the mean T2T implementation score was 11% in phase I intervention sites and 13% in phase II sites.
• After the intervention, T2T implementation score improved to 57% in the phase I intervention sites and to 58% in the phase II sites.
• Intervention sites from phase I sustained the improvement during the phase II (52%).
• Predictors of greater T2T improvement included having only rheumatologist providers at the site, academic affiliation of the site, having fewer providers per site, and the rheumatologist provider being a trainee.
