Hypothesis

What is the incidence, consequences, nature, and preventability of surgical adverse events among hospitalized patients?

Conclusion

Surgical adverse events occur more frequently than other types of adverse events and are often preventable, leading to more severe consequences.

Supporting Evidence

  • Surgical adverse events occurred in 3.6% of hospital admissions.
  • 65% of all adverse events were attributable to surgical specialties.
  • 41% of surgical adverse events were considered preventable.
  • Surgical adverse events led to more severe consequences than other types of adverse events.

Takeaway

When people have surgery, sometimes things go wrong, and this study found that many of those mistakes could be avoided with better training and procedures.

Methodology

A structured record review study of 7,926 patient records was conducted in 21 Dutch hospitals to identify adverse events during hospitalizations.

Potential Biases

Inter-rater agreement for the judgment of adverse events was fair, which may introduce bias in the assessment.

Limitations

The study may underestimate the number of surgical adverse events due to reliance on recorded information in patient records.

Participant Demographics

Patients from 21 Dutch hospitals, including university, tertiary teaching, and general hospitals.
