The focus in medical analyses is primarily put on the diagnosis of illness. This is the best strategy, if the onset of an illness has a precise beginning and ending. In all processes, where either the beginning and/or the ending is less well-defined as precise point in time, the progression, as phase in or phase out of illness, is also of substantive interest. A duration analysis can inform about the potential presence of a co-morbidity in case, for example, an infection continues beyond the normally expected duration.
Financial pressures in the medical systems makes it necessary to release patients in a timely fashion. Therefore, has become more important to monitor patients even after release from hospital. Digital devices can support such a monitoring.
The study by Josi Levi and co-authors (2026) shows that smartphones or just the monitoring of the number of steps of patient offers a rather reliable indicator on the health status towards the end. The information that a patient has recovered to the normal level of activities as before the onset of the illness works quite well as indicator of recovery. A more precise measure of the duration of an illness is important for patients, care persons, the health system overall. The duration is one of the cost-intensive factors of any illness and it is surprising how little we know about the issue of time and duration in many health processes.
