Article: Tailored Text Messaging Intervention for HIV Adherence: A Proof-of-Concept Study.
[show abstract] [hide abstract]
ABSTRACT: Objective: This study sought to determine if dynamically tailored medication messages delivered to people living with HIV (PLWH) via text messaging would be well received and enhance adherence and clinical outcomes. Methods: A preexperimental proof-of-concept study with 52 men who have sex with men (MSM) recruited from a health clinic focused on promoting the well-being of gay, lesbian, bisexual, and transgender people. Inclusion criteria were being an English speaking HIV-positive MSM, aged 25 or older. Participants also had to agree to allow access to their medical records, have a cell phone, and be able to receive text messages over the 3-month intervention period. Participants completed baseline surveys that assessed various demographic, social, and health questions; received text messages over 3 months; answered weekly adherence questions via two-way messaging; and completed a follow-up survey at the end of the intervention period. Clinical outcomes were abstracted from participants' medical records at baseline and follow-up. Self-reported medication adherence and clinical outcomes, including CD4 counts and viral load. Results: Participants were receptive to the text messaging intervention, and reported reading and liking the messages. Self-reported medication adherence significantly improved among participants who began the study as nonadherent and received tailored medication reminders. Overall viral load significantly decreased and CD4 count significantly increased from baseline to follow-up. Conclusions: The results demonstrate that using two-way text messaging to dynamically tailor adherence messages may enhance adherence and improve important clinical outcomes for PLWH.

Article: Addressing HIV knowledge, risk reduction, social support, and patient involvement using SMS: results of a proof-of-concept study.

ABSTRACT: Men who have sex with men continue to be severely and disproportionately affected by the HIV/AIDS epidemic in the United States. Effective antiretroviral therapy has altered the HIV epidemic from being an acute disease to a chronic, manageable condition for many people living with HIV. The pervasiveness, low cost, and convenience of short message service suggests its potential suitability for supporting the treatment of conditions that must be managed over an extended period. The purpose of this proof-of-concept study was to develop, implement, and test a tailored short message service-based intervention for HIV-positive men who have sex with men. The messages focused on reducing risk-taking behaviors and enhancing HIV knowledge, social support, and patient involvement. Participants reported strong receptivity to the messages and the intervention. The authors detected a statistically significant increase in HIV knowledge and social support from baseline to follow-up. Among participants who received sexual risk reduction messages, the authors also detected a statistically significant reduction in reported risk behaviors from baseline to follow-up. Results confirm the feasibility of a tailored, short message service-based intervention designed to provide ongoing behavioral reinforcement for HIV-positive men who have sex with men. Future research should include a larger sample, a control group, multiple sites, younger participants, and longer term follow-up.Journal of Health Communication 01/2012; 17 Suppl 1:128-45. · 1.61 Impact Factor
