Compliance with evidence-based guidelines for treatment of patients with heart failure improves in-hospital and post-discharge survival rates
Hospital compliance with the Organized Program to Initiate
Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF)
guidelines is improving both in-hospital and post-discharge survival rates in
the USA, according to an article in the July 23 issue of the Archives of Internal
Medicine.
The initiative 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 outcome 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 Gregg C. Fonarow, MD,
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.”
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 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 Internet-based
program that allowed hospitals to review data in real time and compare them with
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 left ventricular 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, prescribing of aldosterone antagonists increased from
11 to 20 percent, and 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 trends were favorable 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.
