Does higher surgeon and hospital volume improve long-term survival after radical cystectomy?
High-volume providers were associated with improved long-term mortality rates compared with low-volume providers. This finding was independent of the effect of volume on perioperative mortality, suggesting that provider volume effects continue to manifest long after surgery.
These results are unlikely to be directly causal; however, educational failures seem to be part of the complex causal pathway to drunk driving and even to alcohol-related disorders.
