About this study

Official title: Boston Medical Center Ultrasound Decongestion Study

The purpose of this study is to analyze the utility of a novel five-point ultrasound as a predictor of volume overload in diverse patients who are admitted with volume overload/congestive heart failure (CHF) exacerbation at Boston Medical Center (BMC), the largest safety-net hospital in New England. Current standard of care (SOC) involves the utilization of laboratory markers and physical exam, which is often inconsistent and equivocal. The investigators will assess will assess if ultrasound-assisted diuresis reduces recurrent episodes of volume overload/decompensated heart failure.

Read the detailed description

This superiority randomized clinical trial will compare the therapeutic intervention of five-point ultrasound-guided diuresis with standard of care diuresis for decompensated heart failure. Participants with heart failure exacerbation will be randomly allocated in a 1:1 ratio using heart failure patient lists, by a heart failure physician in the emergency department or on the floors. Similarly, patients will be randomly selected in a 1:1 ratio in the outpatient heart failure infusion clinic when seen for heart failure exacerbation by a heart failure physician. The study population will be generally stable and can be inpatient or outpatient.

The primary objective of the study is to evaluate and compare the efficacy of diuresis when driven by standard of care or five-point ultrasound to guide clinical decision making by assessing 30-day hospital readmission rate in patients undergoing standard of care vs ultrasound assisted diuresis.

The specific aims are:

Aim 1. To measure and compare changes in ultrasonographic parameters (ultrasound Doppler profiles, VExUS scores) through the course of a HF hospitalization for decongestion for acute decompensated HF admission.

Aim 2. To compare 30-day and 90-day HF readmission rates between randomized patients with HF admission comparing SOC to VExUS-guided decongestion strategy.

Aim 3: To compare worsening renal failure/acute renal injury (defined as 25% increase in serum Cr/cystatin C from time of admission to 4 weeks post-discharge) between randomized admitted HF patients comparing SOC to VExUS-guided decongestion strategy.

Secondary objectives include:

  1. To assess differences in diuretic responsiveness in individuals with varying cardiac dysfunction (i.e., length of stay for patients with HFpEF vs HFrEF)
  2. To assess differences in diuretic responsiveness in individuals with varying right ventricular function
  3. To assess differences in hospital length of stay between SOC and VExUS-guided decongestion groups
  4. To assess differences in 30- and 90-day mortality between SOC and VExUS-guided decongestion groups
  5. To assess differences in need for renal replacement therapy between SOC and VExUS-guided decongestion groups

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Five-point ultrasoundDevice

    In-person study visits will be done on initial evaluation and then at least every 48 hours, during which serial five-point ultrasound will be performed to assess venous congestion. Each visit will not be at strict intervals; a reasonable time window is every 48 hours +/- 12 hours. Ultrasound may be performed more frequently if clinically indicated. During these visits or between them, ultrasound of the heart may additionally be performed. Each visit will last between 10 and 60 minutes.

  • Standard of careOther

    Standard of care will most likely include radiographic investigations (chest X-ray, chest CT), laboratory evaluation (complete blood counts, metabolic panel, B-type natriuretic peptide, high-sensitivity troponin, electrolytes, renal function, urine testing), volume status, and cardiopulmonary physical exam.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. VExUS Doppler profiles and scores

    The range of VExUS profiles and scores to guide clinicians with heart failure diuresis are: No congestion (normal inferior vena cava), Minimal congestion (0 or 1 abnormal doppler patterns). Mild congestion (2 abnormal patterns and portal vein pulsatility fraction [PVPF] less than 30%), Moderate congestion (2 abnormal patterns and PVPF between 30 and 50%), Severe congestion (2 abnormal patterns and PVPF more than 50%).

    Measured: At admission, At discharge (on average 3-10 days)

  2. 30-day hospital readmission rate

    The number of any hospital readmissions within 30 days of discharge will be abstracted from the participants' electronic medical records.

    Measured: 30 days after discharge (on average 3-10 days)

  3. 90-day hospital readmission rate

    The number of any hospital readmissions within 90 days of discharge will be abstracted from the participants' electronic medical records.

    Measured: 90 days after discharge (on average 3-10 days)

  4. Worsening renal failure/acute renal injury

    This outcome is defined by an increase in 25% of serum creatinine or serum cystatin C from the time of admission to 4 weeks post discharge. It will be abstracted from the participants' electronic medical records.

    Measured: admission to 4 weeks post discharge (on average 3-10 days)

Secondary outcomes (4)
  1. Hospital length-of-stay for decompensated heart failure

    The total number of days hospitalized for decompensated heart failure will be abstracted from the participants' electronic medical records.

    Measured: At hospital discharge (on average 3-10 days)

  2. 30-day HF readmission rate

    The number of readmissions within 30-days of hospital discharge that are specifically due to HF

    Measured: 30 days post discharge (on average 3-10 days)

  3. All-cause mortality

    All-cause mortality will be abstracted from the participants' electronic medical records.

    Measured: 30 days, 90 days

  4. Need for renal replacement therapy

    The need for renal replacement therapy will be abstracted from the participants' electronic medical records.

    Measured: 30 days, 90 days
