What was done
A simulation-based experimental study evaluated how decentralizing nursing support spaces affects nurse walking distance and time. The computational model incorporated task frequency data from a nationwide survey of 700 registered nurses (RNs) and simulated 12-hour day shifts on a 30-bed medical-surgical unit while systematically manipulating the physical locations of 8 nursing support spaces.
What was found
Depending on the specific level and layout of decentralization, total nurse walking time was reduced by up to 67.9% compared to baseline centralized configurations. No other quantitative metrics or confidence intervals were reported in the abstract.
Why it matters
Architectural decentralization of support spaces can substantially decrease non-productive transit time for nurses, potentially freeing time for direct clinical care.
Limits
The study is a theoretical computer simulation rather than a prospective trial in an operational hospital. It did not directly measure patient outcomes, clinical safety metrics, workflow interruptions, or real-world implementation feasibility.
