BENCHMARKS: Space planning in labor and delivery

This is a rule-of-thumb provided by Hayward & Associates, a health care facility planning firm, that may be used to plan for a labor and delivery area.  In the following ratios, LDR means labor-delivery-recovery.  LDRP means the same except adds a postpartum stay in the same room – this is also known as single-room maternity care.

Space planning based on annual births

  • 100 to 200 births / LDRP room if the LDRP concept is used exclusively
  • 300 to 400 births / LDR or LDRP room if some patients are moved to a separate postpartum room after discharge

Recommended departmental gross square feet (DGSF) and departmental gross square meters (DGSM) are also given in this brief article.

SPACE PLANNING: How to determine number of ORs needed

Tips for the planning process for a new surgical suite are given in this brief newsletter article by an experienced health care architect.  There are some interesting facts that are otherwise difficult to find in the literature:

  • What is the difference between an operating room and a procedure room?
  • What is a hybrid operating room?
  • How are some of the metrics used defined – room time, room turnaround time, throughput?
  • What is a target room turnaround time? (“…usually 15 to 20 minutes”)
  • How many hours are procedure rooms open? (“Most procedure rooms are available eight hours per day for a total of 480 minutes per day”)

Scheduling efficiency: A scheduling efficiency factor is multiplied by the annual minutes available per procedure room to account for periods of time that a case cannot be scheduled.  This factor may range from 70 percent for ORs or procedure rooms used for complex (and sometimes unscheduled) procedures — such as cardiothoracic, neurosurgery, and trauma/orthopedics — to 90 percent for an outpatient suite where all procedures are scheduled.”  (page 3)

ED DESIGN: 8 to 12 exam rooms in independent freestanding emergency departments

Architect Jon Huddy, an expert in emergency department planning and design, has written a second edition of his landmark handbook on ED design, which has just been released by the American College of Emergency Physicians.  Here are some of his observations about sizing of emergency departments.

  • 8 to 12 exam rooms is the “sweet spot” for independent freestanding emergency departments
  • Freestanding emergency departments that are part of hospitals tend to have more exam rooms than those that are independent
  • 1,300 to 1,500 patients/room/year has been a typical planning metric for main hospital EDs
  • 1,800 patients/room/year has been a planning metric for main hospital EDs with lower acuity patients and shorter length of stay
  • 1,800 to 2,200 patients/room/year for a new freestanding emergency department — that typically starts operation with lower acuity patients and ramps up to those with more complex, time-consuming problems over time
  • 1,700 to 1,900 patients/room/year for established freestanding emergency departments – he advises clients to go with an average of 1,800 as a starting point for planning discusisons
  • 2,200 to 2,400 patients/room/year might work for urgent care centers
