A total of 148 patients with psoriasis were allocated to a text message or control group. Patients in the intervention group received a text message every day for 12 weeks, providing treatment reminders or educational tools.
At the end of the research, adherence to treatment was 6.46 days per week, an increase from 3.86 days per week at the beginning of the study. No significant variation in the control group was observed.
At the beginning and end of the study, a skin severity assessment was carried out for all patients. After 12 weeks, greater improvement was found in the text message group than in the controls.
The study authors said the use of text messages could help with the long-term management of patients with psoriasis, leading to increased compliance with therapy, positive changes in self-care behaviour and a better doctor/patient relationship.
Three-quarters of the patients said that they would like to continue using the text messaging system and 85% said they found the service useful.
