Effects of telephone-based peer support in patients with type 2 diabetes mellitus receiving integrated care: a randomized clinical trial.

Abstract：

IMPORTANCE:In type 2 diabetes mellitus (T2DM), team management using protocols with regular feedback improves clinical outcomes, although suboptimal self-management and psychological distress remain significant challenges. OBJECTIVE:To investigate if frequent contacts through a telephone-based peer support program (Peer Support, Empowerment, and Remote Communication Linked by Information Technology [PEARL]) would improve cardiometabolic risk and health outcomes by enhancing psychological well-being and self-care in patients receiving integrated care implemented through a web-based multicomponent quality improvement program (JADE [Joint Asia Diabetes Evaluation]). DESIGN, SETTING, AND PARTICIPANTS:Between 2009 and 2010, 628 of 2766 Hong Kong Chinese patients with T2DM from 3 publicly funded hospital-based diabetes centers were randomized to the JADE + PEARL (n = 312) or JADE (n = 316) groups, with comprehensive assessment at 0 and 12 months. INTERVENTIONS:Thirty-three motivated patients with well-controlled T2DM received 32 hours of training (four 8-hour workshops) to become peer supporters, with 10 patients assigned to each. Peer supporters called their peers at least 12 times, guided by a checklist. MAIN OUTCOMES AND MEASURES:Changes in hemoglobin A(1c) (HbA(1c)) level (primary), proportions of patients with attained treatment targets (HbA(1c) <7%; blood pressure <130/80 mm Hg; low-density lipoprotein cholesterol <2.6 mmol/L [to convert to milligrams per deciliter, divide by 0.0256]) (secondary), and other health outcomes at month 12. RESULTS:Both groups had similar baseline characteristics (mean [SD] age, 54.7 [9.3] years; 57% men; disease duration, 9.4 [7.7] years; HbA(1c) level, 8.2% [1.6%]; systolic blood pressure, 136 [19] mm Hg; low-density lipoprotein cholesterol level, 2.89 [0.82] mmol/L; 17.4% cardiovascular-renal complications; and 34.9% insulin treated). After a mean (SD) follow-up period of 414 (55) days, 5 patients had died, 144 had at least 1 hospitalization, and 586 had repeated comprehensive assessments. On intention-to-treat analysis, both groups had similar reductions in HbA(1c) (JADE + PEARL, 0.30% [95% CI, 0.12%-0.47%], vs JADE, 0.29% [95% CI, 0.12%-0.47%] [P = .97]) and improvements in treatment targets and psychological-behavioral measures. In the JADE + PEARL group, 90% of patients maintained contacts with their peer supporters, with a median of 20 calls per patient. Most of the discussion items were related to self-management. CONCLUSIONS AND RELEVANCE:In patients with T2DM receiving integrated care, peer support did not improve cardiometabolic risks or psychological well-being.
