SNOWMASS, COLO. – Under intense fiscal pressure to curb early hospital readmissions for heart failure, cardiologists and hospital administrators are taking a hard look at the traditional role of the emergency department as the point of triage for patients with decompensated heart failure.
“Alternatives to the emergency department for ambulatory triage and intervention are essential,” Dr. Akshay Desai said at the Annual Cardiovascular Conference at Snowmass.
“Traditionally, when our patients become decompensated, we send them from our office or clinic to the ED. And 80%-90% of those who present to the ED with the diagnosis of heart failure are admitted to the hospital. So this means that the ED is a pretty ineffective triage point for heart failure patients. Most ED staff are concerned about ambulatory follow-up and feel it’s safer to follow patients in the hospital. The message here is we need a more robust ambulatory framework to manage patients with milder decompensation so they don’t all need to come into the hospital,” said Dr. Desai of Brigham and Women’s Hospital and Harvard Medical School, Boston.
Hospital admission is of questionable value for a large fraction of decompensating heart failure patients. After all, not that much happens to them in the hospital that couldn’t take place in a less costly setting.
“For the most part, our patients in the hospital for decompensated heart failure get IV diuretics, with an average weight loss of about 4 kg. Surveillance is typically once- or twice-daily laboratory tests and a bedside clinical visit by a physician at 7:30 in the morning. Few patients get much else. There’s little diagnostic testing, few other therapies that require intensive monitoring, and most patients feel a little better by their first day in the hospital,” he said.
This suggests the need for what he called “an evolved model of heart failure care” in which the ED is replaced as the point of service by some form of ambulatory center that can serve as a buffer limiting the number of patients who need to come into the hospital.
“It could be a home-based strategy of IV diuretic administration, a clinic-based strategy of outpatient diuretic administration, or an observation unit based in the ED. All of these are now being tested in various models across the country as alternatives to help manage the readmission problem, and also to make life better for our patients, who’d prefer not to be in the hospital if they could be managed in other ways,” Dr. Desai continued.
Reducing 30-day readmission rates after a hospitalization for heart failure is seen by health policy makers as an opportunity to simultaneously improve care and reduce costs. But studies show only about half of readmissions in patients with heart failure are cardiovascular related, just half of those cardiovascular readmissions are heart failure related, and only about 30% of heart failure readmissions are truly preventable. However, wide variation exists across the country in risk-adjusted 30-day readmission rates, suggesting there is an opportunity for improvement in outlier hospitals.
Numerous factors have been linked to high heart failure readmission rates, including patient sociodemographic characteristics, comorbid conditions, and serum markers of heart failure severity. One underappreciated factor, in Dr. Desai’s view, is that readmission rates are significantly higher in hospitals that are financially and clinically resource poor, as shown in a Harvard School of Public Health analysis of Medicare claims data for more than 900,000 heart failure discharges. These resource-poor hospitals provide care for underserved populations, and they are experiencing a disproportionate burden of the financial penalties imposed for early readmission.
“As we seek to improve care for patients with heart failure, we should ensure that penalties for poor performance do not worsen disparities in quality of care,” according to the Harvard investigators (Circ. Cardiovasc. Qual. Outcomes 2011;4:53-9).
