Increased Volume = Better Outcomes
Numerous studies show the quality of the health
care provided increases with the number of patients
treated by a health system and its physicians.
The additional resources of a large hospital
or health system like Penn, combined with a greater
number of experienced physicians provide patients
with a better chance of early diagnosis and quicker
access to the latest treatment.
The Agency for Healthcare Research and Quality
(AHRQ), created by the federal government to
improve quality, effectiveness and access to
health care services in America, says patients
should feel confident with the care they receive
if the health system they choose has the following
level of experience in six specific procedures:
Procedure* |
AHRQ
Annual Standard |
UPHS

Esophageal
surgery |

Pancreatic
surgery |

Abdominal

Coronary

Percutaneous
transluminal coronary angioplasty |

2302 |
Carotid

The three hospitals of the University of Pennsylvania
Health System — Hospital
of the University of Pennsylvania, Penn
Presbyterian Medical Center and Pennsylvania
Hospital — far exceed
the recommended level of experience in all six
procedures.
The Guide to Inpatient Quality Indicators,
published regularly by AHRQ, uses volume data
on these six procedures along with other measures
to establish threshold standards for quality
of care. The rationale for the volume measures
is based on evidence that hospitals performing
more of certain intensive, high-technology, or
highly complex procedures tend to have better
outcomes for those procedures.
