Hypothesis

Do characteristics of the catheterization unit affect the wait time of the cardiac surgery unit?

Conclusion

The characteristics of the catheterization unit directly and indirectly impact the wait time of the cardiac surgery unit.

Supporting Evidence

  • Wait time of the catheterization unit has a direct positive impact on the wait time of the cardiac surgery unit.
  • Capacity of the catheterization unit positively influences the demand of the cardiac surgery unit.
  • Demand of the catheterization unit does not significantly impact the demand of the cardiac surgery unit.

Takeaway

If the first part of heart care takes longer, the next part will also take longer. So, we need to look at how each part of heart care affects the others.

Methodology

The study used published data from 11 hospitals in Ontario, Canada, from 2005 to 2008, and employed Partial Least Squares-based Structural Equation Modeling for analysis.

Limitations

The study relied on aggregated data published quarterly, which may not capture all variations, and used a proxy for catheterization capacity due to unavailable specific data.

Participant Demographics

Data from 11 hospitals in Ontario, Canada.
