One key factor contributing to extended DUP is service delay \u2013 the time from initial contact with psychiatric services to diagnosis. Reducing service delay depends on prompt identification of psychosis. Patients with schizophrenia and severe social impairment have been found to have prolonged DUP. Whether service delay significantly contributes to prolonged DUP in this group is unclear.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472425000195_as2\">\n\t    <jats:title>Aim<\/jats:title>\n\t    <jats:p>To examine and compare the course of illness for patients with schizophrenia who are homeless or domiciled, with a focus on service delay in detecting psychosis.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2056472425000195_as3\">\n\t    <jats:title>Method<\/jats:title>\n\t    <jats:p>In this case\u2013control study, we included out-patients with a schizophrenia spectrum diagnosis and who were homeless or domiciled but in need of an outreach team to secure continuous treatment.

Mean service delay was significantly longer in the homeless group (5.5 years) compared with the domiciled group (2.5 years, <jats:italic>P<\/jats:italic> = 0.001), with a total sample mean of 3.9 years. Similarly, DUP was significantly longer in the homeless group, mean 15.5 years, versus 5.0 years in the domiciled group (<jats:italic>P<\/jats:italic> &lt; 0.001). Furthermore, the homeless group had an earlier onset of illness than the domiciled group but were almost the same age at diagnosis.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec
