Show moreDuring the past fifty years, mental and behavioral health treatments and patient needs have changed drastically within the psychiatric field. However, architecture and design characteristics of a mental healthcare facility have not adapted to meet the demands. In addressing numerous aspects related to psychiatric care, a new hospital design needs to emerge in order to better serve those in need of treatment related to mental and behavioral health disorders. The design of a Mental and Behavioral Health Facility should focus on and incorporate recent healthcare design theories, such as Evidence-based Design and Biophilic Design Theories. The integration of current theories will aid in the development of a healing environment that will support the successful functioning of the facility and patient/family treatment. Facility designs must consider staff areas, inpatient and outpatient care, rehabilitation and family/patient education, as integral components that contribute to the treatment of mental health disorders and illness.
