Clinical Performance Indicators
Some Research Questions
▪ Do late/early doses of aminoglycoside antibiotics have direct
clinical effects that influence outcomes of care?
▪ Are their practice differences among nurses in administering
opioids for pain control?
▪ Is there a relationship between medication administration
complexity and nurse workload?
▪ Are delays in administering medications related to high workload,
high acuity shifts?
▪ Do long time between drug pickup (Pyxis) and administration
identify potential interruptions in nurse workflow?
Future Directions
▪ Real-time information systems
▪ Comparison across different
settings
▪ Follow “patient” across all
encounters
▪ Link all providers to each patient,
family, community
▪ Performance based analysis
▪ Share/compare data
▪ Value-driven healthcare

Summary Points
What do you take away today?
• Better understanding how to use existing data (including cost data) to improve
care
• Optimize clinical and operational environments of care
• Move towards a data-driven and value-based nursing practice model
• Provide the “best” nursing care at the highest quality and lowest cost
(the value equation) = best outcome
• The value of nursing can only be described when the financial impact is
included
Healthcare Costs
Grocery Store Problem
▪ How much do things cost?
▪ How much do you have to spend?
▪ What are bargains?
▪ What if there was no price?
▪ What if everything was the same
price?
32
Cost of Care
▪ How much does care cost at your
institution?
▪ What are costs, quality, and
outcomes of INDIVIDUAL patients?
▪ How does YOUR hospital compare to
other hospitals?

Healthcare Utilization
▪ Supply vs. demand for healthcare
services
▪ Roemer’s Law
▪ Over served vs. under served?
▪ Rural vs. urban
▪ Utilization of services by
population
Gawande, A. (2009). The Cost Conundrum What a Texas town can teach us about health care. The New Yorker.
http://www.newyorker.com/reporting/2009/06/01/090601fa_fact_gawande?printable=true
The Healthcare Price Problem
▪ Why do hospital charges vary so
much?
▪ How much does it cost me to . . .
▪ Does competition increase costs
to patients?
▪ Why is utilization higher in some
parts of the country?
The Healthcare Price Problem
▪ Tylenol $1.50/pill
(Amazon, $1.49/100 pills
▪ Gauze pads: $77
Walgreens “a few dollars”
▪ Troponin lab: $199.50
(Medicare $13.94)
▪ CBC lab: $157.61
(Medicare $11.02)
▪ Accu-Check diabetes test strips
$18/each
(Amazon $27/box of 50 = $0.55)
Medicare Provider Utilization and Payment Data
▪ Provider and claims based
▪ Fee for service
Homework/Project
Problem
Analysis
▪ Limited access to primary care in
rural CO
▪ How many counties in CO do not have
hospitals:
http://www.unitedstateszipcodes.org/co/
(merge zip -> county data)?
▪ Changing demographics (older
population, providers moving
from rural areas, etc.)
▪ How many MD and APRN/PA providers are in
each county ?
▪ Lack of specialty care
▪ What are the top 10 procedures for each
county?
▪ No hospitals in the community
▪ What are total billables for each county?
▪ What is the change in providers from 2012 to
2013 data?
▪ What are total unique patients for each year
2012-2013?
Potential Solution
Community Paramedics
More information?
▪ EMS/Fire Department based
▪ Knowledge of community
▪ How many ambulance runs per
county and per number of unique
patients (see prior) 2012-2013
▪ Mobile
▪ How many ambulance runs in
counties with no hospitals?
▪ Technology capable, e.g.
telehealth, point of care labs
▪ Number of emergency visits and
hospitalizations for each year by
county (note some counties will not
have hospitals)
▪ How many non emergency
transports
