Incontinence is a common problem among older people with dementia. It can be especially difficult to manage for individuals who are in the later stages of Alzheimer’s disease and are unable to express their needs. Incontinence products, such as adult diapers, are used, but if left unchecked, lying in soiled diapers can lead to discomfort, anxiety, distress, skin breakdown and bedsores. Caregivers are left with the difficult task of regularly checking soiled diapers to ensure no problems arise. 

To alleviate the need for frequent diaper checks by caregivers and the problems that arise from prolonged wearing of wet diapers, Philip Yap, M.R.C.P., proposes the development of a wetness alert diaper. The diaper will be equipped with a sensor to measure the level of wetness in the diaper. Based on a predetermined threshold, the sensor will generate a signal to a nearby receiver when the wetness threshold is exceeded. The receiver will then notify the caregiver via an e-mail, a flashing light or an audio signal that a diaper change is needed. 

The development of a wetness alert diaper may improve the quality of care for bedridden individuals with dementia. In addition, the burden of frequent diaper checks will be reduced for caregivers who will then be freed to provide additional care to others.
