As noted in a previous post, pressure sores are a common problem I see on housecalls. In order to monitor pressure sores, it is necessary to assess their severity (An excellent description here from WebMD) as well as keep records of the progress. In my experience managing patients at home, it can be useful if family or caregivers are able to record the progress of pressure sores with photos.Mobile apps can be a useful tool for such monitoring purposes. The IUVO app was designed by some colleagues and myself in order to facilitate this.
