A Cluster Randomized Trial Comparing Strategies for Translating Self-Management Support into Primary Care Practices

Introduction: Self-management support (SMS) is a key factor in diabetes care, but true SMS has not been widely adopted by primary care practices. Interactive behavior-change technology (IBCT) can provide efficient methods for adoption of SMS in primary care. Practice facilitation has been effective in assisting practices in implementing complex evidence-based interventions, such as SMS. This study was designed to study the incremental impact of practice education, the Connection to Health (CTH) IBCT tool, and practice facilitation as approaches to enhance the translation of SMS for patients with diabetes in primary care practices.

Methods: A cluster-randomized trial compared the effectiveness of 3 implementation strategies for enhancing SMS for patients with diabetes in 36 primary care practices: 1) SMS education (SMS-ED); 2) SMS-ED plus CTH availability (CTH); and 3) SMS-ED, CTH availability, plus brief practice facilitation (CTH + PF). Outcomes including hemoglobin A1c (HbA1c) levels and SMS activities were assessed at 18 months post study initiation in a random sample of patients through medical record reviews.

Results: A total of 488 patients enrolled in the CTH system (141 CTH, 347 CTH + PF). In the intent-to-treat analysis of patients with medical record reviews, HbA1c slopes did not differ between study arms (CTH vs SMS-ED: P = .2243, CTH + PF vs SMS-ED: P = .8601). However, patients from practices in the CTH + PF arm who used CTH showed significantly improved HbA1c trajectories over time compared with patients from SMS-ED practices (P = .0422). SMS activities were significantly increased in CTH and CTH + PF study arms compared with SMS-ED (CTH vs SMS-ED: P = .0223, CTH + PF vs SMS-ED: P = .0013). The impact of CTH on SMS activities was a significant mediator of the impact of the CTH and CTH + PF interventions on HbA1c.

Conclusion: An interactive behavior change technology tool such as CTH can increase primary care practice SMS activities and improve patient HbA1c levels. Even brief practice facilitation assists practices in implementing SMS.
