Background Attainment of every performance measure or perfect care (PC) is used as a tool for measuring hospital
quality of care. We sought to describe the effect of achieving PC on subsequent outcomes in patients admitted with acute
coronary syndrome (ACS) and to determine whether computerized physician order entry enabled with decision support (CPOE-
DS) would enhance the likelihood of achieving PC and improvements in clinical outcomes.
Methods Clinical inpatient data, performance measures and subsequent mortality was collected in 1,321 consecutive
ACS patients admitted between January 1, 2009, to October 15, 2011, using either a standardized order set that followed
consensus guidelines or orders generated via CPOE-DS.
Results CPOE-DS generated orders were utilized in 642 (49%) patients while the remaining 679 (51%) of patients were
admitted using standardized order sets. At baseline, CPOE-DS patients were younger (-3%, P = .006), had lower resting heart
rates (-3%, P = .012), higher TIMI risk scores (+19%, P b .001), were less likely to have hypertension (85% vs. 90%, P =
.014), and more likely to have ST-segment elevation myocardial infarction (17% vs 10%; P = .001) than patients admitted with
standard orders. Patients admitted using CPOE-DS were 5.7 times more likely to achieve PC than those who were admitted
with standard orders (P b .001). Independent predictors of survival included PC (HR, 0.45; P b .001), age ≥67 years (HR,
2.34; P b .001), and abnormal presenting heart rate (HR, 1.71; P = .046).
Conclusions Achievement of PC is a valid measure of quality of care in the hospitalized ACS patient and is associated
with improved survival. CPOE-DS is feasible in the care process for ACS and can increase attainment of PC. (Am Heart J
2012;164:29-34.)
Acute coronary syndrome (ACS) constitutes approxi-
mately 1.3 million hospital discharges per year in the
United States at a cost of $35 billion in hospital charges.

In those patients who survive the index hospitalization,
the risk of further cardiovascular complications including
recurrent myocardial infarction (MI), sudden cardiac
death, heart failure, and stroke are substantial.

There is
clear evidence from randomized clinical trials and
consensus guidelines that in-hospital initiation of key
pharmacotherapies and interventions can substantially
reduce short and long-term mortality and morbidity in
ACS patients.

Yet despite promulgation of these
recommendations, several studies have documented
poor performance and a high degree of hospital and
physician variability in meeting guideline standards,
suggesting inadequacies in the organization and delivery
of care.

Computerized physician order entry enabled with
decision support (CPOE-DS) can present an attractive
avenue for improving process of care and is well suited
for the complex algorithms governing the ACS patient.
Decision support software has established benefit in
other disease states including venous thromboembolism
and has demonstrated efficacy at reducing medication
errors and adverse clinical outcomes.

To focus greater attention at deficiencies of care in ACS,
the American Heart Association (AHA) and American
College of Cardiology (ACC) have co-developed guide-
line-based “performance measures” for ACS patients
which has been adopted by various health agencies
