mHealth consumer apps: the case for user-centered design.

mHealth applications, or “apps” as they are more commonly known, offer the opportunity to improve healthcare delivery and clinical outcomes. The ability to monitor patients remotely can enable patient risk-factor management and improve treatment compliance, thus allowing early detection of medical complications and ultimately preventing unnecessary hospitalizations. In addition to enhancing the delivery of care, one of the most significant opportunities that mHealth offers is in the consumer health domain, allowing patients to actively engage in and self manage their condition. Mobile phones also allow for the design of timely interventions based on user behavior. mHealth-mediated behavioral interventions can produce cognitive, behavioral, emotional, and social health-oriented responses. As such, mHealth apps are particularly appropriate for problems where treatments depend on patient behavioral change, such as those related to smoking, obesity, diabetes, and other chronic conditions. Despite the many potential benefits of mHealth apps, pilot studies aimed at evaluating the effectiveness of mHealth interventions have yielded mixed results. Furthermore, a quarter of all app downloads are used only once. Consumers often do not return to applications that do not immediately engage them, therefore undermining the intervention’s potential effectiveness. Regrettably, there is no simple formula for designing engaging and effective mHealth apps. Currently, many electronic health (eHealth) and mHealth interventions are designed on the basis of existing healthcare system constructs and may not be as effective as those that involve end users in the design process. Moreover, designers often base their designs on assumptions that are not validated with primary user input. The resulting systems may lack key features, and subsequent evaluations of the effectiveness of the interventions may be compromised. For this reason, we employ the user-centered design (UCD) process—an evidence-based approach informed by the needs and understanding of a specific end-user group. In our experience, designing mHealth and other apps, UCD plays a key role in achieving user engagement, thus improving the likelihood of the intervention’s effectiveness. The World Health Organization agrees, and advises that user evaluation be incorporated into the mHealth project lifecycle to ensure effective outcomes. mHealth Consumer Apps The Case for User-Centered Design
