The purpose of this cluster randomized trial is to determine whether an intervention implemented in a General Surgery, based in improving patient-provider communication, results in a better diabetes self-management in patients with lower educational level. A secondary objective is to assess whether telephone reinforcement enhances the effect of such intervention.

Condition Intervention
Diabetes Mellitus Type 2 Other: Face-to-face Other: Face-to-face intervention plus telephone reinforcement

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention

Primary Outcome Measures:
  • Glycosylated Haemoglobin levels [ Time Frame: one year ]

Enrollment: 184
Study Start Date: February 2011
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Intervention A
Face-to face intervention
Other: Face-to-face
is carried out by the GPs during the clinic visit and consists of seven visits, one every three months. Each session consists of completing a diabetes care record sheet (DCRS) together with the patient. The DCRS consists of two parts: Five questions on self-care activities in the last three months and a graph with previously measured HbA1c levels. This information is completed at each session, resulting in a graph showing the evolution of glycaemic control related to self-care activities. The DCRS is explained patients, emphasising the relationship between self-care and glycemic control. At the end of the session, patients are given a copy of the DCRS and suggested to show it and discuss it with their relatives.
Experimental: Intervention B
Face-to-face intervention plus telephone reinforcement
Other: Face-to-face intervention plus telephone reinforcement
In this group patients receive the above described intervention A plus a telephone reinforcement It consists on five telephone calls lasting about 10 minutes each, to provide advice on carrying out physical exercise and eating a balanced diet and to encourage the use of health services related to diabetes control. Any problems or doubts that patients have stemming from any aspect of diabetes care are also discussed. Telephone reinforcement is carried out by a professional who has previously been trained in promoting T2DM self-management and in motivational interviewing techniques.
