Time trends in observed 30-day mortality: public and private hospitals. Over time, we note a decrease in 30-day mortality both in public and private hospitals with a more significant improvement in the private sector. IC95%, 95% confidence interval.

3. Figure 2
Variations in odd ratios (OR) on 30-day mortality by surgeon or hospital volume. The blue curve symbolizes the modelized odds variation by hospital volume for 30-day mortality within the Epithor database. The red curve symbolizes the odds variation by surgeon volume for 30-day mortality within the Epithor database. The reference value is 46 procedures per year by surgeon (OR = 1) corresponding to the mean number of procedures done by a given surgeon within Epithor. The lowest OR is estimated for 89 procedures by year (OR = 0.722), whereas the highest OR is estimated for 30 major procedures per year (OR = 1.081).
