A new surgery-specific safety questionnaire (SAQ) effectively measures operating room safety climate. Patient safety perceptions vary significantly across hospitals, enabling performance benchmarking and intervention evaluation.

Area of Science:

  • Healthcare Management
  • Patient Safety
  • Surgical Operations

Background:

  • Patient safety is critical in surgery, with sentinel events having severe consequences.
  • Existing patient safety initiatives lack reliable measurement tools for front-line providers.
  • A valid method is needed to assess the impact of safety interventions in the operating room.

Purpose of the Study:

  • To develop and validate a surgery-specific safety questionnaire (SAQ).
  • To measure the safety climate among operating room (OR) caregivers.
  • To assess variations in safety climate across hospitals and professional roles.

Main Methods:

  • Developed and administered the SAQ to 2769 OR caregivers across 60 hospitals.
  • Utilized MANOVA and ANOVA to compare safety scores by hospital and caregiver position.

Related Experiment Videos

  • Performed multilevel confirmatory factor analysis to validate the SAQ's structure at the OR level.

    • Main Results:

    • Achieved a 77.1% response rate (2135 participants).
    • The SAQ demonstrated high validity and internal consistency (alpha = 0.76).
    • Safety climate scores varied significantly by hospital (P < 0.001) but not by professional position.

    Conclusions:

    • The SAQ is a valid tool for measuring surgical safety climate.
    • Significant inter-hospital variation in safety climate provides a basis for benchmarking.
    • SAQ scores can effectively evaluate the impact of patient safety interventions.
