RESUMO
BACKGROUND: In Europe, psychiatric disorders seem to affect up to 50% of the homeless. In Portugal there were, at a certain time, circa 3,396 homeless people, half living in the capital city, Lisboa. AIMS: The Homeless Outreach Psychiatric Engagement for Lisboa (HOPE 4 Lisboa) was created, in January 1st 2022, as a collaboration including staff from the local state asylum, medical school and town hall in Lisboa, Portugal, in order to provide better treatment for the super difficult cases of psychiatric patients living homeless in Lisboa. METHOD: During 2022, the HOPE 4 team made night rounds, every 15 days on Tuesday's night (20:30 to 23:30) trying to reach, at least, one dozen of homeless psychiatric patients, previously identified. RESULTS: The HOPE 4 Lisboa interviewed 101 patients (53.4%) out of the 189 programed visits. From this group, 72 (72%) had already a previous psychiatric diagnosis. From those 101 patients, reports for 47 (47%) were sent for an eventual compulsory psychiatric assessment. From those 47 only 21 patients (21%) were admitted in the psychiatry ward. Finally we discuss the most super difficult patient we found, as a small case report: a John Doe living in complete Diogenes syndrome. CONCLUSIONS: there are still a few psychiatrists interested in treating homeless people completely or partially out of the classic mental health care systems. Some claim to be doing interstitial psychiatry, others street psychiatry, but we could also call it marontology.
