Brief Summary
The explanatory mechanism of the relationship between the volume of surgical procedures performed by individual hospitals and the occurrence of serious adverse events is not clear. Based on the " practice makes perfect " dogma, we will explore whether a learning effect can explain the volume-outcome relationship for complex surgical procedures using a nationwide dataset. Especially, we assume that increasing volume of procedures over time may be associated with improved outcomes.
