Peer Support Impact in Adults with T2D & Depression

Diabetes Care; ePub 2018 Oct 29; Cherrington, et al

Peer support decreased acute care visits and hospitalizations for patients with type 2 diabetes (T2D) and depressive symptoms but not for those without depressive symptoms, a new study found. The cluster-randomized controlled trial included adults with T2D who wanted help with self-management. Intervention participants received 1 year of peer support. Control participants received usual care. Researchers found:

  • At baseline, half of the sample reported mild depressive symptoms, and one-fourth reported moderate depressive symptoms.
  • 168 intervention (6 clusters) and 187 control (5 clusters) participants had follow-up data.
  • In those with mild depressive symptoms, the incidence rate ratio (IRR) for hospitalization among intervention vs control was 0.26 per 10-patient years.
  • The IRR for AC was 0.55 per 10 person-years.
  • Findings were similar for those with moderate depressive symptoms.
