Background: Crisis resolution and home treatment (CRHT) is an emerging mode of delivering acute mental health care in the community. There is a paucity of knowledge regarding the workings of CRHT in the literature. This is the third paper in a series of three from the longitudinal survey of patients of a CRHT team in Norway, which was aimed at describing the characteristics of patients served, professional services provided, and clinical outcomes. This report focuses on the changes in morbidity and clinical problems from admission to discharge and the length of service. Methods: The study was a descriptive, quantitative study based on the patient data from a longitudinal survey of one CRHT team in Norway. The participants of the survey, a total of 363 patients, were the complete registration of patients of this team in the period from February 2008 to July 2009. Results: The findings indicate that the patients' mental health status improved from admission to discharge, although many patients were discharged with the same mental health symptoms as those present at admission. However, one third of the patients were discharged with no clinically significant mental health problems. The majority of the patients of the CRHT team on the other hand seemed to be those with long-standing mental health problems, who were likely to be in need of continuing mental health care even after the resolution of mental health crises. There is a need for a coordinated system of community-based mental health services for patients with long-standing mental health problems, within which CRHT teams can play a pivotal role in making connections between the crisis-care and the recovery-oriented care. The mean length of service was around 15 days with variations by the clinical problem types, with the patients in the psychosis group having the shortest duration and the patients in the depression group having the longest duration.
