  abstract = {<strong>Objective</strong>: To study the impact of
  nurse-to-patient ratios on patient length of stay (LOS) in computer
  simulations of Emergency Department (ED) care.
  <strong>Methods</strong>: Multiple 24-hour computer simulations of
  emergency care were used to evaluate the impact of different minimum
  nurse-to-patient ratios related to ED LOS, which is composed of wait
  (arrival to bed placement) and bedtime (bed placement to leave bed).
  <strong>Results</strong>: Increasing the number of patients per nurse
  resulted in increased ED LOS. Mean bedtimes in minutes were impacted by
  nurse-to-patient ratios.
  <strong>Conclusions</strong>: In computer simulation of ED care,
  increasing the number of patients per nurse resulted in increasing delays
  in care (i.e., increasing bedtime).},
