Stabilization of glycemic control and improved quality of life using a shared medical appointment model in adolescents with type 1 diabetes in suboptimal control

Background: Declining glycemic control in type 1 diabetes (T1D) during adolescence persists despite treatment advances. Non-adherence, peer relations, diabetes burnout, risk taking, transition to autonomy, family conflict, and poor quality of life (QOL) are recognized barriers. Shared medical appointments (SMAs) in adolescent T1D may offer benefits, but data are limited. Our objective was to determine whether SMAs, with multi-component interventions utilizing multidisciplinary teams, improve glycemic control and psychosocial outcomes in poorly controlled adolescent T1D.

Methods: SMAs focused on self-management, communication skills, goal setting, glucose pattern recognition, and peer/diabetes team support. SMAs included: individual history and physical, labs, surveys, multidisciplinary educational ice breakers, group session, and individual wrap up. Outcomes were QOL, adherence, and retrospective and prospective glycemic control. Three to six subjects and families came to 3 SMAs and 1 individual appointment every 3 months over 9 months.

Subjects: A total of 37 English speaking subjects, ages 12-16 yrs, with T1D ≥ 1 year, and hemoglobin A1c (HbA1c) 7.5-11% enrolled. Thirty-two subjects attended 75% of visits, meeting inclusion criteria.

Results: HbA1c worsened in the 9 months before study (ΔHbA1c= 0.7 ± 1.2; p < 0.01), but remained stable during study (ΔHbA1c = 0.01 ± 1.2; p > 0.05). There were significant improvements in overall QOL (p = 0.005), school function (p = 0.006), psychosocial function (p = 0.008), barriers (p = 0.02), adherence (p = 0.01), and communication (p = 0.02). Improvements in school function and communication reached clinical significance.

Conclusion: SMAs are feasible replacements to individual appointments in adolescent T1D, stabilizing glycemic control and improving QOL. Randomized controlled trials with optimizations are needed to further explore and refine this intervention.
