Pancreatic resection is a complex surgical procedure.
Although its associated mortality has decreased
significantly over time, morbidity remains high. A strong
volumeoutcome relation has been demonstrated for
pancreatic resection, with decreases in the mortality, hospital
length of stay, and cost when performed in high-volume
hospitals.1,2 Despite these compelling data, complete
regionalization of pancreatectomy to high-volume centers
has not been achieved, with 2040 % of pancreatic
resections still being performed at low-volume centers.2,3 There
is evidence that failure of regionalization is driven, in part,
by patient preferences and physician referral patterns. In
Texas, 19 % of patients traveled a distance farther than the
distance to the nearest high-volume hospital to have their
operation performed at a low-volume hospital. Finlayson
and colleagues found that only 55 % of patients were
willing to travel to a high-volume center even if told that
their mortality risk was double at their local facility. Also,
only 82 % were willing to travel if told that their mortality
risk was sixfold higher at their local facility.4
Even across high-volume centers, there is significant
variability in outcomes.5 Given the wide variability in
outcomes and the challenges and reality of regionalization,
it is critical to explore alternative approaches to improving
overall outcomes as well as closing the quality gap
observed between high- and low-volume providers.
Healy et al.6 provide data to suggest that participation in
a regional quality improvement collaborative may provide
an alternative model to improving outcomes for patients
undergoing pancreatic resection. Leveraging data from an
already existing statewide surgical quality collaborative,
the authors demonstrate improvement in risk-adjusted
morbidity, mortality, and failure to rescue rates for
pancreatectomy between two time periods, 20082010 and
20112013. Importantly, the majority of the observed
improvement in outcomes was due to attenuation of the
variation in outcomes across low- and high-volume
hospitals. Adjusted mortality rates (from 6.2 to 3.3 %) and
major complication rates (from 27.8 to 22.2 %) improved
over time in low-volume hospitals. However, there was a
slight increase in the mortality rate (from 0.8 to 1.1 %) and
morbidity rate (from 17.8 to 20.0 %) at high-volume
hospitals, although this increase is likely not statistically or
clinically significant. When evaluating these outcomes, the
reader should understand that this collaborative effort was
not procedure-specific. It did not assess
pancreatectomyspecific outcomes across institutions, nor was it a true
collaboration between centers to learn from each other and
drive further improvement.
Regardless of these drawbacks, the data suggest that a
collaborative approach to quality improvement could
provide another important piece of the puzzle.
Pancreatectomyspecific improvement occurred even when it was not the
primary goal of the collaborative design. Therefore, it is
reasonable to extrapolate that a procedure-specific
collaborative could help hospitals and physicians improve
outcomes for complex procedures. Ideally, collaboratives
would provide benefit beyond the outcomes reporting by
learning from one another and implementing strategic
interventions, ultimately improving global outcomes. These
results, in turn, could lead to a reduction in the variation
between low- and high-volume providers as well as
improved outcomes at all centers. For example, instead of
improving overall pancreatic fistula rates by bringing the
low-volume centers to the current level of the high-volume
centers, the collaborative could identify best practices that, if
shared, might engender improvement at all centers, truly
raising the bar.
A general quality collaborative, such as that described
by Healy et al.,6 may be most beneficial for addressing
broader process measures and complications. These items
could include appropriate antibiotic use, prevention of
ventilator-associated pneumonia, implementation of
enhanced recovery protocols to be used after surgery, and
avoiding inappropriate blood transfusions. Such
approaches would drive improvement across all procedures.
A true procedure-specific collaborative could provide
additional advantages for improving outcomes for relatively
uncommon complex procedures such as pancreatectomy. It
would allow inclusion of a larger number of hospitals
performing specific complex procedures, standardization of
definitions, and collection of relevant procedure-specific
variables (e.g., pancreatic fistula, delayed gastric
emptying). Ideally, the participating hospitals would learn from
each other and drive improvement by identifying and
implementing interventions guided by practices that produce
the best outcomes.
Regardless of the obvious advantages, there are
challenges to implementing a collaborative approach. It requires
a nonpunitive approach, and significant trust must exist
between participating hospitals to obtain the full benefit.
Differences in hospital systems may prevent large-scale
implementation of best practices identified at the
highestperforming (and likely highest-volume) centers. As
resources such as intensive care, access to imaging, ancillary
services, and availability of specialty physicians are
probably not going to be equal among the hospitals, such
disadvantages must be considered when developing a
national collaborative.
To have the greatest impact, institutions participating in
true collaboratives (regional or procedure-specific) must
learn from each other to drive improvement beyond that
seen by simply measuring and reporting outcomes in a
blinded fashion. True collaboratives would ideally develop
consensus and trust across participating institutions,
creating greater buy-in and participation. Not only should we
strive to bring poorly performing centers toward the current
mean performance through collaboration, we should strive
to raise the bar and achieve truly improved outcomes.
