Exact: ~33% of hospitals had designated healing gardens
By 2000–2025, approximately 33% of hospitals had designated healing gardens
The systematic review documents the historical adoption of biophilic design, noting that in the 2000–2025 period, roughly one-third of hospitals (∼33%) had designated healing gardens, and a similar proportion (33–40%) had integrated nature access or views. By the early 2010s, approximately 50% had art-nature programs, reflecting a substantial shift from the utilitarian hospital design of earlier decades.
