Ascertainment of care-seeking is important in public health management in order to plan national health programs and assessing quality of health care. Nguyen et al. demonstrated use of GPS-based devices for ascertainment of hospitalisations [14].

At the same time, however, this new capacity for surveillance has raised issues related to privacy, confidentiality, access to information.
