Human factors significantly impact surgical outcomes, with major failures increasing risks of death and near misses. However, implementing effective human factors defenses can mitigate these risks and lead to successful arterial switch operations.

Area of Science:

  • Cardiovascular Surgery
  • Surgical Outcomes Research
  • Human Factors Engineering

Background:

  • Surgical outcomes are influenced by numerous factors, including patient-specific variables and procedural complexities.
  • The role of human factors in surgical performance and patient safety remains an area requiring further investigation.

Purpose of the Study:

  • To investigate the impact of human factors on surgical outcomes using arterial switch operations as a model.
  • To analyze the relationship between human failures and adverse events in a series of complex cardiac surgeries.

Main Methods:

  • Collected data included patient-specific variables, procedural details, and observations from a human factors researcher.
  • Developed a multivariable model to assess the influence of human factors on outcomes, adjusting for baseline patient variables.

  • Analyzed major and minor human failures identified from observational reports.

    • Main Results:

    • Overall mortality was 6.6%, with 24.3% of cases experiencing death or near misses.
    • Major human failures were strongly associated with increased risk of death and near misses (P <.001).
    • Appropriate human factors interventions significantly reduced the risk of death (P =.003), while minor events also correlated with adverse outcomes.

    Conclusions:

    • Human factors play a critical role in determining surgical outcomes, particularly in complex procedures like arterial switch operations.
    • Effective implementation of human factors defense mechanisms can significantly improve patient safety and reduce adverse surgical events.
