Researchers at the University of Technology, Sydney have developed the Person-Centred and Environment Care Assessment (PCECAT) tool. PCECAT is a self-assessment instrument designed to assist managers of residential aged-care homes to assess whether care practices are person-centred and whether the environment supports person-centred care. The comprehensive PCECAT tool is based on a questionnaire with guidelines in a handbook. The assessment takes six to eight hours per facility, and is intended to be conducted every six to twelve months to provide longitudinal evaluation.
