Accommodation of special populations: Patients with hearing or speaking impairments will be accommodated with the help of translator. The person who regularly attends visits with her will facilitate this, or if no such person is available, we will use a hospital translator. All patients will receive an explanation of the study and the consent form in writing. All material will be understandable by patients with a grade 6 reading level. If our patients have lower than a grade 6 reading level, we will ask them if there is a family member at home who could assist them with the use of the mobile device.
