Objective: Decreasing reimbursement provided by third-party payers necessit
ates reduction of costs for providing critical care services. If academic m
edical centers are to remain viable, methods must be instituted that allow
cost reduction through practice change.
Methods: We used short cycle improvement methodology to rapidly achieve the
se goals, Short cycle improvement methodology involves identifying the area
s for improvement, defining a mechanism to evaluate outcome, initiating an
improvement plan on a small number of patients, and repeating the cycle wit
h new adjustments based on outcome. Baseline data on areas for improvement
was prospectively collected, and protocols to initiate change were develope
d and tested by short improvement cycles, Outcomes were evaluated, protocol
s were modified, and another cycle was performed. This methodology was cont
inued until the desired goals had been achieved. To adjust outcomes for sev
erity of illness, Acute Physiology and Chronic Health Evaluation II methodo
logy was used. Using this methodology, we focused on three areas for improv
ement, Standing orders for laboratory studies, electrocardiograms, and ches
t x-ray films were eliminated. Protocols were developed for the appropriate
use of sedation, analgesics, and neuromuscular blocking agents. Finally, a
protocol for weaning from mechanical ventilation was developed to allow re
spiratory therapists to proceed through the weaning process, which was orde
red by a physician,
Results: Laboratory tests were reduced by 65% (from 510 to 180 tests per da
y) with an annual cost savings of $21,593, Chest x-ray reduction of 56% res
ulted in an annual savings of $3,941, There was a 75% reduction in cost of
neuromuscular blocking agents. The use of neuromuscular blocking agents res
ulted in a 75% reduction in drug costs. Ventilator hours were reduced by 35
% from 140 to 90 hours, The average length of overall intensive care unit s
tay was reduced by 1.5 days (5.0 to 3.5 days), The cost per patient day dec
reased with an annualized cost savings of 4% per patient day. Unexpected ou
tcomes included a reduction in intensive care unit days from 54 days at bas
eline to 7 days at the 6-month interval, The infection rates for blood stre
am infections, urinary tract infections, and nosocomial pneumonia were redu
ced. Using national nosocomial infection data, these rates represented a re
duction from the fiftieth percentile to the twenty-fifth percentile for all
measured indicators, Acute Physiology and Chronic Health Evaluation II sco
res were 19.54 at baseline and increased to 21.2 (p = 0.001) at the 6-month
interval. Mortality rates were 16.7% at baseline and were 17.6% (p = 0.89)
at the 6-month interval.
Conclusion: We concluded that utilization of short cycle improvement method
ology provided an ongoing method for reducing costs of critical care servic
es in our patient population with no change in mortality.
