RESUMEN
Investigators conducting research involving human subjects are obligated to safeguard the wellbeing of the study participants. Other than requiring investigators to establish procedures for ongoing monitoring and reporting of adverse events, federal regulations do not dictate how human subject safety should be ensured. A variety of data safety monitoring (DSM) procedures may be acceptable depending on the nature, size, and complexity of the study. However, practical guidance for establishing and implementing appropriate DSM plans for such studies are lacking. In this article, we provide a review of the DSM considerations associated with monitoring health remotely and describe the Pocket Personal Assistant for Tracking Health project as an exemplar for how to develop effective DSM plans for research that captures clinical data using remote health-monitoring devices. Protecting the safety and welfare of participants is one of the most important mandates for research involving human subjects. Investigators have an ethical and scientific responsibility to monitor the safety of research participants. Investigators typically fulfill this responsibility by monitoring and reporting adverse events.
