Area of Science:

  • Orthopedic Surgery
  • Health Services Research
  • Operating Room Management

Background:

  • Increasing demand for total hip arthroplasty (THA) and total knee arthroplasty (TKA) necessitates improved operating room (OR) efficiency.
  • Optimizing OR workflows is critical for meeting patient needs and managing healthcare resources effectively.

Purpose of the Study:

  • To examine the impact of implementing time benchmarks on the efficiency of primary TKA and THA procedures.
  • To determine if establishing benchmarks increases the number of joint replacements performed per day.

Main Methods:

  • A retrospective review of 295 primary TKA and THA cases across 59 OR days was conducted.
  • Established benchmarks included anesthesia preparation time (APT) <11 min, procedure time <72 min, anesthesia finish time (AFT) <21 min, and turnover <22 min for 4 joints in 8 hours.
  • Patient demographics, time points, and adverse events were recorded to analyze benchmark adherence and influencing factors.

Main Results:

  • High adherence rates were observed for procedure time (95.25%) and AFT (99.67%).
  • Overall, 98.3% of OR days completed 4 joint replacements within 8 hours, and 52.5% completed 5 joint replacements.
  • Factors such as age, body mass index, and surgical laterality influenced the ability to meet specific time benchmarks.

Conclusions:

  • Establishing time benchmarks successfully enabled the completion of 5 joint replacement procedures within an 8-hour OR day.
  • This efficiency was achieved without an increase in resource utilization.
  • Key factors influencing OR efficiency for high-volume primary hip and knee replacements were identified.
