Subject Evidence-Based Design in hospitals. Problem What role can Evidence-Based Design have in the design of better hospitals? Purpose To determine spatial (or: concrete) qualities, scientifically proven to have a positive influence on the health and well being of patients and staff, in order to offer the architect a helping hand for designing better hospitals. These measures are drawn from research that has been done in the framework of Evidence-Based Design (EBD), which can be perceived as the scientific variant of the healing environment. Relevance In the Dutch media the term healing environment is often used by architects, representatives of hospitals and researchers. Everyone provides their own content (colour, nature, treatment, hospitality, etc.) to this collective concept. The determination of concrete design elements, with a proven positive effect for patients, can contribute to the design of better care environments. Method and approach Literature research and case studies. EBD → elements → checklist → case studies in field research ↑ --- analysis --- ↑ Spatial measures were selected from scientific articles from Evidence-Based Design research that are applicable for an architect. Only those measures were selected for which the effect has been proven sufficiently. The selection was based on scientific articles that have been validated by EBD expert teams. The measures in this study cover waiting rooms, consultation rooms, nursing departments, patient rooms and day treatment areas. The measures have an effect on: • A positive contribution to the health of patients (chapter 3); • A positive contribution to the well being (less anxiety, stress) of patients (chapter 4); • A positive contribution to the efficiency and effectiveness of staff (chapter 5). The literature research gives information on how physical environmental interventions can contribute to the problems of the patient (such as lack of sleep). The selected measures are gathered in a checklist. This checklist gives an overview of all the ...
