A systematic review of the psychometric properties of instruments for assessing the quality of the physical environment in healthcare.

AIM To identify instruments measuring the quality of the physical healthcare environment, describe their psychometric properties. BACKGROUND The physical healthcare environment is regarded as a quality factor for health care. To facilitate evidence-based design there is a need for valid and usable instruments that can evaluate the design of the healthcare environment. DESIGN Systematic psychometric review. DATA SOURCES A systematic literature search in Medline, CINAHL, Psychinfo, Avery index and reference lists of eligible papers (1990-2016). REVIEW METHOD Consensus based standards for selection of health measurement instruments guidelines were used to evaluate psychometric data reported. RESULTS Twenty-three instruments were included. Most of the instruments are intended for healthcare environments related to the care of older people. Many of the instruments were old, lacked strong, contemporary theoretical foundations, varied in the extent to which they had been used in empirical studies and in the degree to which their validity and reliability had been evaluated. CONCLUSIONS Although we found many instruments for measuring the quality of the physical healthcare environment, none met all of our criteria for robustness. Of the instruments, The Multiphasic environmental assessment procedure, The Professional environment assessment protocol and The therapeutic environment screening have been used and tested most frequently. The Perceived hospital quality indicators are user centred and combine aspects of the physical and social environment. The Sheffield care environment assessment matrix has potential as it is comprehensive developed using a theoretical framework that has the needs of older people at the centre. However, further psychometric and user-evaluation of the instrument is required.
