Patient Room Design

Same-handed vs mirrored

A same-handed room places the bed, headwall, and bathroom in the same orientation across every room on the unit. Mirrored rooms save shell space by sharing plumbing walls but force clinicians to reorient every time they cross the corridor. Evidence — including work from the Center for Health Design's Pebble Project — favors same-handed for error reduction, especially for medication and IV-line procedures.

Sightlines

Direct, unobstructed sightlines from the corridor into the bed — through glass walls, angled doors, or open thresholds — are consistently linked to lower fall rates and faster response. Decentralized nurse stations placed between every two rooms are a companion pattern.

Light, sound, and privacy

The three design choices with the strongest evidence base:

• Access to daylight — associated with shorter length of stay in multiple observational studies (Ulrich, 1984 and follow-ups).
• Sound-absorbing materials — NRC ≥0.90 ceilings; sound-rated doors reduce cross-corridor speech.
• Single-patient rooms — lower cross-infection, better sleep, higher HCAHPS.

Dimensional standards

Design frameworks

• FGI Guidelines for Design and Construction of Hospitals.
• Center for Health Design — Evidence-Based Design (EDAC) body of knowledge.
• ADA Standards for Accessible Design.
• NFPA 99 and NFPA 101 — life safety.
