Although they join the SMS reminder, I still remind them: A process evaluation of SMS reminder implementation in routine antiretroviral therapy care in Indonesia
This process evaluation of an SMS reminder intervention for ART retention in Indonesia found that while the tool was feasible and perceived as useful by stakeholders, its overall impact was limited by low implementation reach, fidelity issues, confidentiality concerns, and infrastructural challenges, highlighting the need for strengthened human resources and integrated digital systems to ensure success.

Living with HIV requires a daily commitment to taking medication, a routine that keeps the virus in check and allows people to live long, healthy lives. However, maintaining this routine is difficult for many. Life gets in the way; stress, forgetfulness, or the fear of being seen taking medicine can cause people to miss doses or skip clinic visits. When treatment stops, the virus can return, and the risk of passing it to others increases. To help people stay on track, health systems around the world have turned to mobile phones. Sending a simple text message to remind someone to take their pills or visit a doctor is a low-cost idea that has shown promise in many places. The question, however, is not just whether these messages work, but whether they can be successfully woven into the busy, complex reality of everyday hospital and clinic life, especially in countries with fewer resources.
In Indonesia, researchers set out to test exactly this. They introduced a system called HATI-SMS, a digital tool designed to send automated text reminders to people starting HIV treatment. The goal was to see if this technology could help patients remember to pick up their medicine and attend their appointments. The study took place in three major cities, involving dozens of clinics and hospitals. The researchers did not just look at whether patients took their pills; they watched closely how the system was actually used by doctors, nurses, and the patients themselves. They wanted to understand the human side of the technology: who used it, who found it helpful, and what got in the way.
The results showed that the idea was sound, but the execution faced significant hurdles. The system was offered to nearly 800 people who were eligible, but only about half were actually invited to join, and of those, most agreed to participate. Once enrolled, the vast majority received at least one text message. The messages themselves were well-received by many patients, who described them as a comforting sign that someone was looking out for them. For some, the text was a crucial nudge that helped them remember a daily task they might otherwise forget. Health workers also saw the value, noting that the messages could help them communicate with patients more effectively.
However, the system did not run as smoothly as the designers had hoped. The study found that the number of messages actually sent was far lower than the maximum possible number. Several factors contributed to this gap. In many clinics, the internet connection was unreliable, making it difficult for staff to log patient visits into the system in real time. Because the system relied on up-to-date information to send the next reminder, delays in data entry meant that reminders were often sent late or not at all. Furthermore, the staff who were supposed to manage the system were already overwhelmed with their regular duties. In some cases, they were so busy that they could not find the time to enter the data, or they simply forgot to do so.
Confidentiality was another major barrier. While the system allowed patients to choose between direct messages about their medication or more vague, coded messages, many patients were still afraid. They worried that if a family member or neighbor saw a text on their phone, it would reveal their HIV status. This fear led some people to refuse the service entirely, or to stop using it after a few months. The researchers also found that the system sometimes duplicated efforts. In many clinics, staff were already using their own methods to track patients, such as phone calls or personal notes. When the new digital system arrived, it was sometimes seen as an extra task rather than a helpful tool, leading to a lack of engagement.
Despite these challenges, the study concluded that mobile reminders are a viable tool for Indonesia, provided certain conditions are met. The technology itself is not the problem; the issue lies in how it fits into the existing health system. The researchers found that for such a system to work long-term, it needs to be linked directly to the electronic records that clinics already use, rather than existing as a separate, manual process. It also requires dedicated staff who are not already stretched thin by other duties. Without these supports, even a well-intentioned digital tool can struggle to find its place in the daily rhythm of a clinic. The study suggests that while technology can offer a helping hand, it cannot replace the need for strong, well-resourced human systems that prioritize the privacy and well-being of the people they serve.
