Exceptional outcomes for even
the toughest cardiac cases.
The Children’s Heart Center at Lucile Packard Children’s
Hospital Stanford’s outcomes surpass peer hospital averages –
despite tackling the most complex cases in the U.S.
According to recent data from the Children’s Hospital Association’s Pediatric
Health Information System (PHIS), the Heart Center at Lucile Packard Children’s
Hospital Stanford and Stanford Children’s Health has higher marks in key areas
– including survival rates and average length of stay – compared with dozens of
other children’s and young adult cardiac programs nationwide. What makes these
outcomes even more noteworthy is the fact that the Heart Center also has the
highest acuity Case Mix Index (CMI) in the country.*
* Data Source: Pediatric Health Information System (PHIS), 2013 and 2014. The PHIS hospitals are 46 of the largest
and most advanced children’s hospitals in America, and constitute the most demanding standards of pediatric
service in America. The Children’s Hospital Association developed PHIS to provide a rich data source for clinicians
to conduct comparative effectiveness studies that affect hospitalized children.

HIGHER SURVIVAL RATES THAN NATIONAL DATA SET
The Children’s Heart Center’s survival rates were higher than the national data set for PHIS “peer hospitals”:

• In 2014, the Heart Center’s observed-toexpected mortality ratio was 0.63 compared
with an average ratio of 0.83 for PHIS peer
hospitals. This index difference of 0.20
indicates that patients had a 24 percent higher
survival rate at Lucile Packard Children’s
Hospital Stanford compared with the PHIS
national data set.
• This is an even greater difference than
reported the year before. In 2013, the Heart
Center’s patients had an 8 percent higher
survival rate compared with the PHIS national
data set (observed-to-expected mortality ratio
of 0.79 vs. an average ratio of 0.86 for PHIS
peer hospitals, for an index difference of 0.07).
SURGICAL SURVIVAL RATES 56% HIGHER THAN PEERS
When looking specifically at cardiac surgical
care, the Children’s Heart Center’s outcomes
were even more impressive:
• In 2013, an observed-to-expected mortality
ratio of 0.71 vs. an average ratio of 0.92 for
PHIS peer hospitals — an index difference
of 0.21 — indicated the Heart Center’s surgical patients had a 23 percent greater
chance of survival.

• In 2014, an observed-to-expected mortality
ratio of 0.29 vs. an average ratio of 0.66 for
PHIS peer hospitals — an index difference
of 0.37 — means the Heart Center’s surgical
patients had a 56 percent higher survival
rate than the PHIS national data set.

HIGHEST COMPLEXITY CASES IN THE NATION
Adding even more weight to these survival rates is the fact that Lucile Packard Children’s Hospital
Stanford handles the highest acuity and complexity cardiac cases in the country:
CMI: Cardiac Care – Surgical
CY2013 and CY2014
• The Heart Center’s overall surgical CMI in
2014 was 20 percent higher than the PHIS
peer hospital average (6.05 CMI for Stanford
vs. 5.06 CMI for the PHIS national data set,
when adjusted for severity).

Shorter Average Length of Stay
Even while surpassing PHIS peer hospital averages for outcomes, the Heart Center’s average length
of stay (ALOS) for both surgical and medical cases was lower than the PHIS national data sets:
• In 2014, patients who were hospitalized
at Stanford for medical care had an ALOS
that was 1.01 days shorter (4.07 days on
average vs. the PHIS peer hospital average
of 5.08 days).
• In 2014, patients who had surgery at
Stanford spent an average of 3.31 fewer
days in the hospital (7.07 days on average
vs. the PHIS peer hospital average of
10.38 days).

Due to the Heart Center’s willingness to take
on “last hope” cases, a focus on innovation and
discovery is a critical part of the equation.

limits of what should be achievable.”
