Clear concepts regarding what constitutes an inpatient setting are essential for the assignment of patients to inpatient treatment, for effective therapy, and for quality assurance. They help to understand how outpatient, partial inpatient, and full inpatient care can be distinguished or integrated, as well as the roles of each care area. The second edition of the book sharpens the focus on the high relevance of the therapeutic environment, which includes the structural, organizational, and psychological characteristics in both outpatient and inpatient treatment. For treatment planning and execution, the setting variables and therapeutic environments are described, along with their impact on treatment outcomes. The book is aimed at doctors and psychologists, as well as clinic management, quality management officers, and hospital architects.
