Text Messages Have the Power to Improve Health Outcomes

This article is part of a series dedicated to thinking big about technology in healthcare and how it can be used to drive improved communication and better health outcomes.

Spotlight: Communication for Medication Adherence

In the words of Dr. Rob Lamberts, “healthcare is communication.” But what exactly does that mean? One piece of evidence that good healthcare depends on good communication comes from recent studies of patient reminders, which have been shown to increase adherence to healthy behaviors. In the past, these reminders would have been difficult for healthcare teams to manage, but new technologies like texting and automation have now made possible a new era of efficiency and efficacy. 

Research has shown that improved communication has the ability to improve health outcomes, especially in rural and developing regions. A recent review article, for instance, found promising results in six separate studies of SMS text messaging for managing malaria in different regions of Africa where communication has historically been a barrier to treatment.1

In one of the reviewed studies, Zurovac et al. found that text message reminders sent to healthcare workers in a rural Kenyan clinic substantially improved provider compliance with malaria treatment guidelines. The researchers also observed that this improvement persisted beyond the end of the intervention. These are notable results, as guideline compliance is critical both to improving individual treatment outcomes and reducing population-level drug resistance. It is also compelling that these positive findings depended only on simple and low-cost technology, as this implies that the results may be generalizable and potentially impactful for millions of people.

While the success of the Zurovac study is one great example of communication technology improving healthcare, it increasingly seems that the possible applications for innovations like text-message reminders may actually be limitless. For example, many elderly Americans now rely on basic SMS reminders to help them take their medications correctly, and there is a growing demand for even more sophisticated and precise reminders (sneak peak — this will be covered more in depth in next month’s blog).2

Given the clear benefit of technology-enabled “reminder” communications, we’ve also made sure to build features in Spruce that allow healthcare teams to check in with their patients and help them stay on top of everything, from upcoming appointments to important medications. We also built automation around these check-ins so that busy providers don’t have to remember every detail or send every message by hand. The evidence is strong that reminders empower patients to get the care that they need for better outcomes, and we take that seriously. After all, as Dr. Lamberts puts it, healthcare is communication.

Technology has drastically changed the way that healthcare is delivered, because it has changed the way that we communicate with each other. We are inundated with healthcare information in every aspect of our lives. And while this can be overwhelming, there are so many ways that technology and rapid communication can empower us to optimize our health and wellbeing through better access to information.

The fields of healthcare technology and digital health are huge and rapidly growing, forming the basis of ongoing research and innovation. This is where our new blog series comes in: health tech & communication. Here, we’ll focus specifically on the role of technology in healthcare communication as a way to highlight some of the revolutionary change that has transpired in the new digital age. We’ll be featuring some innovative advances and research findings that highlight how diverse groups of people benefit from better healthcare communication.
