Abstract
While there are several types of wearable devices aimed for individuals with epilepsy (IWE) to use, mostly for monitoring seizure activity, there is still no device available that has been proven to prevent or even decrease the risk of Sudden Unexpected Death in Epilepsy (SUDEP) from occurring. Although this is the case, it is thought that SUDEP can possibly be prevented by the use of a nocturnal supervision device. This study aims to try and develop a design concept for a device with the specific goal of SUDEP prevention. We interviewed 4 medical experts, 9 IWE, and 2 caregivers to assess what is needed to detect SUDEP before it occurs and see how end users want the device to look and function. All interviews were qualitatively coded to help guide a design concept for a SUDEP prevention device. Characteristics for the design concept were based on 4 metrics: (1) accessibility, (2) practical functionality, (3) usability, and (4) wearable device type. Monitoring heart rate, blood oxygen saturation, and head positioning during sleep could be used to detect abnormal levels in heart rate or blood oxygen and/or if the individual’s airway is obstructed. IWE/caregivers tended to favor a wristband device, while the medical experts recommended a headband type of design. All interviewees agreed that the device’s price point is an essential aspect to the design process, as an affordable price will increase its chance of use.
