Abstract

LANGE, ILTA et al. Effect of a tele-care model on self-management and metabolic control among patients with type 2 diabetes in primary care centers in Santiago, Chile. Rev. méd. Chile [online]. 2010, vol.138, n.6, pp.729-737. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872010000600010.

Background: Telephone based self-management support may improve the metabolic control of patients with type 2 (DM2) diabetes if it is coordinated with primary care centers, if telephone protocols and clinical guidelines are used and if it is provided by nurses trained in motivational interviewing. Aim: To assess the efficacy ofi a tele-care self-management support model (ATAS) on metabolic control of patients with DM2 attending primary care centers in a low income area in Santiago, Chile. Material and Methods: Two primary care centers were randomly assigned to continue with usual care (control group, CG) or to receive additionally 6 telecare self-management support interventions (IG) during a 15 month period. Glycosylated hemoglobin (HbA1c) was used to measure metabolic control of DM2; the “Summary of Diabetes Self-care Activities Measure” and the “Spanish Diabetes Self-efficacy” scale were used to measure self-management and self efficacy, respectively. Changes in the use of health services were also evaluated. Results: The IG maintained its HbA1c level (baseline and final levels of 8.3 ± 2.3 % and 8.5 ± 2.2% respectively) whereas it deteriorated in the CG (baseline and final levels of 7.4 ± 2.3 and 8.8 ± 2.3 % respectively, p < 0.001). The perception of self-efficacy in the IG improved while remaining unchanged in the CG (p < 0.001). Adherence to medication, physical activity and foot care did not change in either group. In the IG, compliance to clinic visits increased while emergency care visits decreased. Conclusions: The ATAS intervention, in low income primary care centers, significantly increased the probability of stabilizing the metabolic control of patients with DM2 and improved their use of health services.
