Research on the volumeoutcome relationship in health care has generated both a high "volume" (more than 200 Medline-listed publications to date) and a consistently recurring "outcome": the finding that, across a range of interventional procedures, hospitals and surgeons with higher case loads tend to have lower mortality rates (1).
The volumeoutcome relationship has been most striking for certain low-frequency, high-risk operations, such as pancreatectomy and esophagectomy. In particular, U.S. hospitals that performed 11 or more of the latter procedure on Medicare patients between 1984 and 1993 had a fivefold lower 30-day mortality rate (3.4% versus 17.3%) than hospitals that performed between one and five such procedures during the same period (2).
