Opening the Door to Evidence-Based Design Decorative Openings are a Key Factor Evidence-based design seeks to create a therapeutic environment by eliminating visual stressors and emphasizing pleasant décor right down to the smallest details, including doors and hardware. This design principle does not override patient safety or lessen the strict security requirements of a hospital. But it does encourage facilities to seek out security and life-safety solutions that blend in with the rest of the décor. Decorative doors and hardware can contribute to this desired setting. Decorative levers, stylish locks and sleek doors mesh with the building design motif and create the appearance of an open and more relaxed atmosphere.
