A national initiative designed to improve
heart-failure patient care in hospitals proved
effective at increasing hospital's adherence to key
quality-of-care performance measures and reducing the
length of hospital stays for patients.
It also resulted in favorable trends for
in-hospital and post-discharge mortality rates,
according to a UCLA study published in the July 23
edition of the journal Archives of Internal Medicine.
The initiative, called the Organized Program to
Initiate Lifesaving Treatment in Hospitalized Patients
with Heart Failure (OPTIMIZE–HF), is the largest of
its kind undertaken for heart failure in the country,
with 259 hospitals participating, and is the only one
designed to capture patient outcomes data 60 to 90
days after discharge.
"Despite compelling scientific evidence and
national guidelines for use of key life-prolonging
agents and lifestyle changes, gaps exist in heart
failure treatment," said principal investigator Dr.
Gregg C. Fonarow, UCLA's Eliot Corday Chair in
Cardiovascular Medicine and Science, director of the
Ahmanson-UCLA Cardiomyopathy Center and professor of
medicine at the David Geffen School of Medicine at
UCLA. "We hope more hospitals will adopt this
validated model for enhancing heart-failure patient
care."
Heart failure affects 5 million Americans, and
nearly 3.6 million hospitalizations each year are
attributed to the condition, which occurs when the
heart's left ventricle can't pump enough blood to the
body's other organs.
For the study, researchers utilized data from
OPTIMIZE–HF's large heart-failure
performance-improvement registry, which is designed to
help hospitals increase adherence to standard
hospital-based performance measures developed by the
American College of Cardiology and the American Heart
Association, as well as additional evidence-based
measures.
Between March 2003 and December 2004, 48,612
eligible adult heart failure patients at academic and
community hospitals nationwide were enrolled in the
registry. A subgroup of 5,791 patients was followed
for 60 to 90 days after hospital discharge to collect
additional data on outcomes, including mortality and
re-hospitalization rates.
Patients were registered through a unique Web-based
program that allowed hospitals to review data in real
time and compare it to aggregate data from similar
facilities. Information collected included data on
admission, hospital, discharge care and outcomes.
Researchers found improvement in three of four
standard performance measures used by the Joint
Commission on Accreditation of Healthcare
Organizations to gauge quality of heart failure care
at hospitals:
· Giving complete medical instructions to
patients upon discharge increased from 46.8 percent of
cases at the beginning of the study to 66.5 percent by
the study's conclusion.
· Providing smoking cessation counseling to
patients rose from 48.2 percent to 75.6 percent.
· Evaluating the heart's left ventricle
systolic function started at a high rate of 89.3
percent and improved to 92.1 percent.
The fourth measure — prescribing an angiotensin-converting
enzyme or angiotensin II receptor blocker medication
at discharge — remained steady during the study.
Adherence to other performance measures improved as
well. The use of beta-blockers rose from 78 to 86
percent, the prescribing of aldosterone antagonists
increased from 11 to 20 percent and the use of statin
medication rose from 39 to 44 percent.
"We saw substantial and very rapid improvements in
these key performance measures and in providing
essential evidence-based medications for heart
failure," Fonarow said.
With OPTIMIZE–HF, the length of hospital stays
improved significantly, dropping from 7.5 to 6.2 days,
and there were favorable trends for post-discharge
mortality, which dropped from 9.9 to 6.3 percent.
"If similar improvements had occurred at
hospitals nationwide, this would translate to 40,000
less deaths and 1.4 million costly hospital days
eliminated per year," Fonarow said.
OPTIMIZE–HF also provided tools to help hospitals
improve the reliability of heart failure care,
including standardized admission orders, discharge
checklists, pocket cards, medical chart stickers,
best-practice algorithms and critical pathways.
Researchers found that use of these tools impacted
outcomes. In-hospital mortality dropped from 4.1 to
2.5 percent for cases in which hospital staff utilized
standard admission orders to help direct treatment.
Post-discharge death and re-hospitalization rates
decreased from 38.2 to 34.8 percent when tools were
utilized during care.
Fonarow said that the American Heart Association
has adopted OPTIMIZE–HF for use in its Get With the
Guidelines–Heart Failure quality improvement program,
in which more than 400 hospitals nationwide are now
participating.
GlaxoSmithKline sponsored the OPTIMIZE–HF registry
and funded the study. Fonarow has received research
grants and honoraria from GlaxoSmithKline and has
served as a consultant to the company.
