Objective: To evaluate adherence to therapy in acne patients using mobile phones and Short Message Service (SMS) to communicate.
Methods: 160 patients were randomly assigned to two groups: the SMS group received 2 text messages twice a day for a period of 12 weeks; the control group did not receive any messages. Before and after 12 weeks, the following evaluations were performed in all patients: digital photographs, the Global Acne Grading System, the Dermatology Life Quality Index, the Cardiff Acne Disability Index, the doctor-patient relationship evaluated through the Patient-Doctor Depth-of-Relationship Scale, and the adherence to treatment evaluated by asking patients how many days a week they had followed the therapy. For statistical analysis we used Student's t test.
Results: The SMS group had a better improvement of all parameters compared to the control group.
Conclusion: Adherence and compliance are higher for patients who are included in a strategy of control.
