This study introduces an industrial engineering framework to assess operating room (OR) efficiency by measuring time, personnel activity, and resource use. It helps identify key areas for process improvement in surgical settings.

Area of Science:

  • Industrial Engineering
  • Healthcare Management
  • Surgical Operations

Background:

  • Operating room (OR) efficiency is critical for healthcare delivery.
  • Traditional evaluation methods often lack a holistic approach to OR performance.
  • Industrial engineering principles offer robust tools for process analysis.

Observation:

  • A novel framework integrates time studies and work sampling for OR procedure evaluation.
  • Personnel activities are categorized as value-added or non-value-added.
  • Resource utilization is quantified through instrument tray usage, defects, and waste analysis.

Findings:

  • A case study on total knee arthroplasty demonstrated the framework's application.
  • The framework enables simultaneous comparison of time, personnel, and resource utilization.
