摘要：Aims and objectives: To test an automated telephone service as a follow-up and support strategy for self-care in a population of adult Mexican patients with type 2 diabetes. Methods: The design was a two-group comparative design, with pre and post-intervention measurements. Patients were assigned into intervention ( n = 31), or comparison ( n = 33) groups. Over 12 weeks, each participant in the intervention group received automated phone calls with instructions to facilitate accomplishment of the treatment, and self-care activities. Two focus groups helped to appreciate patients’ follow-up experience. Randomized grouping was performed by selecting numbers from an urn; the final sample comprised 31 (48%) patients in the intervention group, and 33 (52%) in the comparison group; these procedures were performed by the case nurse management. The study was approved by the Ethics Committee of the Autonomous University of Nuevo Leon and the University of Michigan; all of the participants signed informed consent. Results: Of the 372 programmed phone calls made to the participants, 234 were completed, representing a 62.9% response rate. Phone calls may be associated to a 0.82% decrease in the HbA1c values and to lower depression scores. HbA1c measurements decreased 0.82% ( M = 7.41 - 6.69; t = 25; 4.11; p = ?0.001) from the baseline values over the 12-week study in the intervention group and 0.49% ( M = 7.24 - 6.75; t = 26; 2.11; p = 0.044) in the comparison group. Variables related to medication intake did not exhibit differences between the baseline and second measurements, except with respect to the scale of depression.
