The associations between daylight sufficiency in hospital wards and patient satisfaction with mental healthcare services: An egyptian sample

Abstract

Introduction: Certain building design and environmental factors are important to characterize in critical building environments, such as psychiatric hospitals, because they influence occupant's comfort, health, indoor environmental quality, and duration of admission. Lighting has its critical importance in hospitals. A sufficient level of daylight is essential to carry out the necessarytasks. Carefully designed daylighting can transform the appearance of the ward and make it attractive, welcoming and even restful. The Aim of Work: In this study is to find the associations between sufficiency in daylight inside psychiatric hospital wards and patient satisfaction with mental healthcare services.Methods: Inpatient wards of psychiatric hospitals were screened for patient's satisfaction towards health care services. Measuring the daylight intensity was performed by using a building performance tool (BPS tool) called Autodesk Ecotect as well as by professional lux meter to ensure the accuracy of the measurements. Measuring the patient's satisfaction was done by using a questionnaire designed by the research team which included six subscales: personal information, care from the staff, overall rating of hospital experience, rating the exterior spaces, rating the interior spacing and patient's enjoyment of life over the last week.Results: Daylight readings and patient's questionnaire were correlated together. In the form of tables, the 1st correlation between daylight intensity and patient's subjective opinion about daylight. The 2nd correlation was between daylight sufficiency and patient's enjoyment of life questionnaire. The 3rd correlation was between window-wall ratio in the ward and patient's visual and thermal comfort.Conclusion: Many positive relationships like daylight intensity with patient's life enjoyment, and WWR with visual and thermal comfort were found.
