This work examined the evidence-based design (EBD) and post-occupancy research of hospital healing gardens.The lack of statutory design guidelines raises concs on how such gardens are created and whether they meet the intended design purpose.This issue is particularly important for hospitals because a neutral or even a negative effect on users can be generated.A systematic analysis of the literature in two databases (Scopus and Web of Science) was undertaken.Results showed that pre-and post-occupancy research findings on hospital healing garden design are sparse and design recommendations vary among users.Despite the lack of research on the design of healing gardens,the review showed that while post-occupancy research findings evaluate the effectiveness of design recommendations,pre-occupancy research findings,combined with site analysis,constitute a traditional approach followed in landscape architecture practice and determine the site and user features that must be addressed for each hospital.Pre-and post-research findings must be considered in the design process to create a successful healing garden.A summary of EBD recommendations for different users is presented,and the need to enrich the existing amount of EBD recommendations is highlighted.
