Access to treatment for HIV/AIDS patients
Trying to improve public health systems in Buenos Aires

Fundacion Huesped, a non-profit organisation based in Buenos Aires, Argentina was started 26 years ago by a group of doctors working in a public hospital in Buenos Aires. They work in Public Health, specifically on infectology, from a human rights perspective.
Challenge: patients getting lost within the public health system
They identified that a major problem is that people get “lost” within the Public Health system–starting treatment, but then not showing up for their next appointment, for example. So, they decided to look at interventions around supporting people as they go through their treatment, looking at potential points at which they drop off or stop their treatment.
To start with, they began looking at the appointment system. Currently, patients have to go in person to make an appointment, between the 1st and the 3rd day of every month, and appointments are only made within the following two months. This is a difficult task for many people; going during certain days, and there are just three days per month when appointments can be made. They used to be able to make appointments within a six month window, but realised that too many patients were simply not turning up.
They identified a specific way to mitigate this: sending reminders to patients that their appointment was coming up, to make sure that appointments were being used, and people were getting the treatment they were scheduled to have.
how to get ‘reminders’ to patients, without violating their privacy?
Patients at this hospital fit into quite a specific demographic; they are attending public hospitals, which means they are likely to be from a low-income background–otherwise they would go to the better resourced, and more expensive, private hospitals. This means they are unlikely to have smartphones, but often feature phones or access to shared landlines, and are big users of Facebook. Many potential users say they “don’t have an email, but they have a Facebook.”
Fundacion Huesped went to a hackathon and developed a calendar tool sending reminders via SMS and email, and potentially Interactive Voice Response (IVR) as well. Their aim with this tool is to remind the patients of their appointments so that they don’t miss them, and decrease the rate of unattended appointments; so naturally, they want to get reminders to the patients using communications channels that are already used by their target demographic.
But most, if not all, of the most commonly used communications channels are largely insecure. Without knowing who has access to those communications channels, how can they be sure that only the person in question will get the message, and not be read or heard by someone else? In the case of shared landlines, they thought about leaving cryptic messages that would mean something to the patient, but be incomprehensible to others who might hear it.
Although they have now developed a tool to address some of the issues associated with making an appointment and receiving reminders to attend the appointment, they are not rolling it out yet. They are very cognisant of the risks here–both in terms of the patients as individuals, and for them as an organisation, due to the National AIDS law that prohibits anyone from identifying people living with HIV/AIDS.
They have met with the Ministry of Health to discuss this law, and what this means for their potential technology solutions. The Ministry of Health encouraged them to go ahead with the project, as “not everybody looking for an appointment at the department was living with HIV/AIDS”–so, essentially encouraging them to base their project on a potential legal loophole.
They are also speaking to private hospitals3 to work out how they deal with these issues, and see if they can gain some insights from the technology solution that they already have in place. Their strategy at the moment is to gather experience and expertise from others, and try and come up with a solution together.
