Text Messaging after HIV and STI Screening: Do Patients' Profiles Matter?

Background Text messaging after sexually transmitted infection (STI)/HIV screening may be a cost-effective means of improving patient care, but it may not be appropriate for all patients. This study aimed to explore the profiles of patients who did not participate in a short message service (SMS) program after STI/HIV testing. Methods In October 2016, 396 patients in Paris were screened for STI/HIV and were invited to complete an anonymous self-administered questionnaire. Patients were offered the possibility of being notified by SMS after testing, 68% accepted (SMS group) and 32% did not (no-SMS group). Each of the 100 patients from the no-SMS group who had completed the questionnaire was matched with the next patient from the SMS group. Factors associated with nonparticipation in the SMS program were studied using conditional logistic regression models. Results Participation in the SMS program was not related to STI screening characteristics (screening results and seriousness of the diseases screened) but seemed to be related to patient characteristics. In multivariate analysis, compared with patients in the SMS group, those in the no-SMS group were more often older, socially less favored (born in Africa or Asia, no university diploma, living outside Paris). They also more often declined to answer sexual questions, which could reflect a need for privacy and discretion. Conclusions Although SMS after STI/HIV screening is well accepted, it does not suit all patients. Several contact options should be proposed to comply with patients' preferences and to reduce the risk of nondelivery of STI screening results.
