Abstract
Background: The episode of care for colorectal surgery in 8 outlier Veterans Affairs Hospitals with high
mortality and the volume outcome relationship in 118 Hospitals are examined.
Methods: A total of 103 deaths were reviewed. Mean age was 74 with 63% of the patients undergoing
emergency surgery; 54% of the patients had malignant disease and 21% had metastatic disease.
Results: Nineteen percent of the patients had a delay in diagnosis, 22% had delay in surgery and 14%
should have received a different surgery usually less radical. In addition, system related issues were
identified in 19% of the cases and practitioner related issues in 20% of the cases. The Spearman rank
correlation between colorectal surgery volume and unadjusted mortality was 0.114 (P = 0.22).
Conclusion: Colorectal surgery death is prevalent in elderly patients undergoing emergency surgery for
malignancy or metastatic disease and is not related to hospital volume. Timely diagnosis, less radical surgery
while optimizing system based pathways might improve outcome. © 2007 Excerpta Medica Inc. All rights

Although quality-of-care measures for colon and rectal sur-
gery have been described, the data relating to structures and
processes of care as they pertain to high mortality in this
field are sparse. The single indicator associated with lower
mortality and higher quality of care revolve mainly around
surgeon and hospital volume of similar cases [1,2]. The
safety of colon and rectal surgery has improved over time:
advances in surgical technique, anesthesia, intensive care,
introduction of modern antibiotic treatment, and other sup-
portive measures now yield a prevailing mortality rate of
approximately 5% [2,3]. Factors predictive of a high peri-
operative death rate have been derived specifically for colon
and rectal surgery from the National Surgical Quality Im-
provement Program (NSQIP) [3,4]. Risk-adjustment meth-
ods also have been described to predict complications and
deaths along with measures to mitigate some of these risks
in elective colorectal surgery [5,6].
In this study, we investigated structures and processes of
care contributing to a higher mortality in patients undergo-
ing elective colon and rectal surgery in 8 of 118 hospitals
within the Veterans Affairs (VA) hospital system. We spe-
cifically examined various domains of care spanning the
overall episode of care for each patient who died after
surgery in facilities detected as high outliers based on actual
mortality of 2 times the national average for that time period
as well as risk-adjusted mortality. We also examined the
relationship between volume of colon and rectal surgery and
mortality in the entire VA system.
Methods
In this study, all patients undergoing colon and rectal
resections were selected from the NSQIP database for anal-
