Hypothesis

Are there gender disparities in the likelihood of being surgically treated for coronary artery disease in Italy, and can these disparities be explained by age and severity of illness?

Conclusion

Men and women in northern Italy with cardiovascular disease are treated differently, and this difference cannot be explained by age or severity of disease.

Supporting Evidence

  • Men were more likely to undergo surgical treatment for coronary artery disease than women.
  • The odds ratio for men undergoing surgery was 2.11 before adjustment for confounders.
  • Even after adjusting for age and severity, gender disparities in treatment persisted.

Takeaway

In Italy, women are less likely than men to get heart surgery, even when they have similar health issues.

Methodology

The study analyzed discharge data from all public and private hospitals in Piedmont, Italy, from 1999 to 2002, focusing on patients with specific cardiac diagnoses.

Potential Biases

Potential biases may arise from the gender of patients influencing physician decisions and diagnostic criteria developed primarily for men.

Limitations

The study relies on administrative data, which may have inaccuracies and incompleteness in clinical coding.

Participant Demographics

The study included 77,974 patients, with women constituting around 32% of the sample.
