Living conditions for persons with severe mental illness (SMI) in Sweden have changed dramatically in recent decades, mainly due to the closure of mental hospitals in the 1990s and the subsequent development of community-based interventions. Thereby, people with SMI have experienced care interventions in various forms, which vary according to how the treatment is institutionally organised over the years. There is, however, a lack of knowledge concerning what care paths persons with SMI have undergone in this fragmented institutional landscape. In this article we present a time-geography-inspired visualisation method to address this. A set of 437 persons, first diagnosed with psychosis between 2000-2004, were studied over 10 years with regard to their contact with various care institutions. We constructed time-geographic paths of intervention for these individuals and visualised them at an aggregate level. The initial exploration conducted using the proposed visualisation method showed gender and age differences in some respects, but also that the initial periods after the psychosis diagnoses were similar in terms of in-patient care interventions among men and women. The proposed visualisation method is promising and should be further developed for deeper analysis of long-term individual paths of intervention.
