A time-motion study on impact of spatial separation for empiric airborne precautions in emergency department length of stay.

Aims: To evaluate the impact of spatial separation on patient flow in the emergency department.

Design: This was a retrospective, time-and-motion analysis conducted from 15 to 22 August, 2022 at the emergency department of a tertiary hospital in Kuala Lumpur, Malaysia.
