Treatment outcomes depend on adherence to the prescribed regimen. A survey published in JAMA Dermatology
(online, 20 March 2015) reveals that 27% of 143 patients prescribed therapy for acne did not collect all their prescribed medicines; this figure was higher than the previously reported rate of 10%.
Levels of non-adherence varied according to the number of treatments prescribed, from 9% in those prescribed just one treatment to 40% for those prescribed two treatments. Patients were more likely to fill electronic prescriptions than paper prescriptions and less likely to adhere to treatment with topical retinoids and over-the-counter medicines than other treatments.
“Simplifying treatment regimens by prescribing products that contain two or more active ingredients could prove effective in reducing non-adherence,” the researchers suggest.
