Protocolized Diuretic Strategy in Cardiorenal Failure (ProDiuS)

Effect of Protocolized Diuretic Strategy on Clinical Outcomes and Health-related Quality of Life in Cardiorenal Failure: A Randomized Trial

This research study is a randomized clinical trial to evaluate if taking diuretics (medications that increase urine production and help with fluid removal from the body) in a standardized fashion (using a guideline for adjusting doses based on measured urine output) could improve health outcomes in patients with cardiorenal failure or cardiorenal syndrome (combined heart and kidney failure) with edema (too much fluid in their arms, legs, and/or lungs). Under usual care, these patients are treated with diuretics and other medications in increasing doses, but not necessarily to maintain a specific amount of urine output per day. Current heart failure (HF) treatment guidelines do not provide any standard protocol, or guideline, for adjusting diuretic doses. At the point when kidney function worsens to the degree that the kidneys are no longer able to respond to the medications used to remove fluid, either ultrafiltration (UF) or dialysis (also called hemodialysis [HD]) is typically started in order to remove fluid. In both UF and dialysis, excess fluid is removed from the body by using a machine. In dialysis, both waste products and fluid are removed and electrolyte abnormalities are corrected. In UF, only fluid is removed. Both procedures use the same machine. This study will test whether a Protocolized Diuretic Strategy (ProDiuS), a plan for adjusting diuretic doses based on measured urine output, will improve clinical care for cardiorenal syndrome. Such a plan for adjusting diuretic doses is needed to improve symptoms, decrease the length of hospital stays and rehospitalization rates, and improve health-related quality of life (HRQOL) in cardiorenal syndrome patients.

Study Overview

• Status: Terminated
• Conditions: Renal Failure; Kidney Failure; Cardiac Failure
• Intervention / Treatment: Drug: Protocolized Diuretic Strategy

Detailed Description

Heart failure (HF) accounts for over 1 million hospital admissions annually in the United States and is a leading cause of disability and healthcare costs. Cardiorenal syndrome and worsening renal function are independent risk factors for morbidity and mortality in HF. Effective fluid removal, manifested by a decrease in body weight, is one of the most important goals of treatment in cardiorenal syndrome. Current medical therapeutic options, including sodium and fluid restriction, diuretics, blockade of the renin-angiotensin-aldosterone system, inotropes, and nesiritide, are suboptimal in patients with advanced cardiorenal syndrome. When medical therapies fail, ultrafiltration (UF) may be used for mechanical fluid removal using dialysis or UF machines. UF can effectively remove fluid in HF patients, but its precise role in the therapy of cardiorenal syndrome is still unclear. A multicenter randomized controlled trial (CARRESS-HF) suggested that UF was not superior to a stepped pharmacologic diuretic regimen, with a similar amount of weight loss with the two approaches and a higher rate of adverse events in the UF group. Therefore, a protocolized diuretic strategy is needed that is superior to current clinical care in the management of cardiorenal syndrome.

Current HF guidelines do not provide any standard protocol for diuretic dosing. The variation in usual clinical care may explain the long hospital stays and worsening renal function common in these patients. One retrospective observational study compared a diuretic dosing protocol to usual diuretic therapy for patients admitted with acute decompensated HF. Protocol diuretic use was associated with greater weight loss and significantly lower risk of 30-day readmission. However, due to its retrospective design, the baseline characteristics of the two groups differed in many pertinent covariates, and its generalizability is limited.

The proposed study aims to determine if a protocolized diuretic treatment strategy, as opposed to usual clinical care, results in improved clinical decongestion, clinical outcomes, and health-related quality of life (HRQOL), while preserving renal function in hospitalized patients with cardiorenal syndrome. It is a prospective randomized single-blind trial with equal allocation (1:1) and random block randomization of 150 participants hospitalized at University of Pittsburgh Medical Center (UPMC) for cardiorenal syndrome recruited over 3 years (approximately 50 participants/year). Participants with cardiorenal syndrome will be randomized to a Protocolized Diuretic Strategy (based on the stepped pharmacologic algorithm used in the CARRESS-HF trial) vs. Usual Care. Participants will be followed daily in the hospital during the treatment period, as well as at 1-month and 3-month follow-up visits in the outpatient HF clinic.

Primary Research Question:

1. In hospitalized patients with cardiorenal syndrome, does a protocolized diuretic treatment strategy, as opposed to usual clinical care, result in improved clinical decongestion based on change in body weight at day 4 or hospital discharge (whichever comes first)? Primary Hypothesis. In hospitalized patients with cardiorenal syndrome, protocolized diuretic therapy will result in greater reduction in body weight and improved clinical decongestion compared to usual care.

Secondary Research Questions:

1. Do clinical outcomes, including length of hospitalization, number of rehospitalizations for HF, and mortality, improve after protocolized diuretic therapy compared to usual care over 3 months? Hypothesis 1. Protocolized diuretic therapy will be associated with reduced length of hospital stay, decreased rehospitalization rates, and decreased mortality, compared to usual care.
2. Do other measures of volume status improve after protocolized diuretic therapy compared to usual care during hospitalization and over 3 months? Hypothesis 2. Protocolized diuretic therapy will be associated with greater decongestion based on increased venous compliance of the internal jugular vein (via Doppler ultrasound), negative fluid balance, and clinical decongestion, compared to usual care.
3. Do HRQOL outcomes improve after protocolized diuretic therapy compared to usual care over 3 months? Hypothesis 3. HRQOL indices in physical well-being, mental well-being, and sleep quality domains will improve after protocolized diuretic therapy compared to usual care.
4. Do renal outcomes (safety endpoints), including renal function changes and need for UF or renal replacement therapy, differ between protocolized diuretic therapy and usual care during hospitalization and over 3 months? Hypothesis 4. Protocolized diuretic therapy will be superior to usual care in terms of worsening renal function and need for UF or renal replacement therapy.

Subgroup Research Questions:

1. Do outcomes differ between the Protocolized Diuretic Strategy vs. Usual care stratified by type of heart failure (e.g., systolic dysfunction (EF <40%) vs. diastolic dysfunction (EF ≥40%); ischemic vs. other; none-mild vs. moderate-severe mitral regurgitation (MR) or tricuspid regurgitation (TR))? Hypothesis 1. No difference will be seen between treatment and control groups based on type of heart failure.

This trial is of utmost interest to cardiologists and nephrologists, who struggle to find the optimal diuretic and medical management strategy to effectively remove excess fluid yet preserve renal function. It is highly relevant to many clinicians and the community at large, as HF and cardiorenal syndrome are a leading cause of hospitalizations and healthcare costs. If a protocolized diuretic strategy can be found that optimally removes fluid in an efficient and safe manner, it could potentially be disseminated to community physicians and/or incorporated into public policy or HF treatment guidelines in order to improve quality of care and reduce healthcare costs in this population with high morbidity and mortality.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
NO_INTERVENTION: Usual Care; Participants randomized to the Usual Care group (control arm) will receive escalating diuretics and medical therapy per HF guidelines published by the American College of Cardiology (ACC)/American Heart Association (AHA) and Heart Failure Society of America (HFSA), dosed in variable fashion at the discretion of the treating cardiologist.
EXPERIMENTAL: Protocolized Diuretic Strategy; Participants randomized to the Protocolized Diuretic Strategy group will receive escalating diuretics according to an algorithm targeting a goal diuresis of urine output (UO) 3-5 L/day with diuretics intensified in a stepped fashion using both loop diuretics given by intravenous (IV) bolus followed by IV continuous infusion (furosemide or alternative loop diuretic at equivalent dose), with or without concomitant thiazide diuretic (oral (PO) metolazone or IV chlorothiazide). If UO is < 3 L/day, diuretic regimen will be increased. If UO is 3-5 L/day, diuretic regimen will be continued at current doses. If UO is > 5 L/day, diuretic regimen will be reduced.	Drug: Protocolized Diuretic Strategy; The Protocolized Diuretic Strategy will administer diuretics according to an algorithm based on based on the "stepped pharmacologic care arm" used by the CARRESS-HF trial investigators. This algorithm targets a relatively aggressive goal diuresis of urine output (UO) 3-5 L/day with diuretics intensified in a stepped fashion using both loop diuretics given by intravenous (IV) bolus followed by IV continuous infusion (furosemide or alternative loop diuretic at equivalent dose), with or without concomitant thiazide diuretic (oral (PO) metolazone or IV chlorothiazide).; Other Names: Diuretic Treatment Protocol; Stepped Pharmacologic Care

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Body Weight (kg) From Randomization to Day 4 or Date of Discharge (Whichever Comes First)	The change in body weight (kg) from randomization to day 4 or date of discharge will be determined by the difference between body weight at day 4 after randomization or date of discharge (whichever comes first) and body weight taken at baseline measured in the hospital on standard scales without shoes and wearing a hospital gown, measured before breakfast and post-voiding.	4 days (96 hours)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Length of Hospitalization	Length of hospitalization will be ascertained from admission date to date of discharge.	1 month
Number of Rehospitalizations for Heart Failure (HF)	Number of rehospitalizations for HF will be ascertained based on chart review of admissions with HF as a coded diagnosis, evidence of clinical volume overload, and treatment with intravenous diuretics.	Up to 3 months (assessed at 1 month and 3 months)
Number of Total Rehospitalizations	Number of rehospitalizations will be ascertained based on chart review of admissions to any hospital after the index hospitalization	Up to 3 months (assessed at 1 month and 3 months)
All-cause Mortality	All-cause mortality will be ascertained based on chart review of vital status (alive/dead) and cause of death.	Up to 3 months (assessed at 1 month and 3 months)
Difference From Baseline to 1 Month in Change in Right Internal Jugular Vein (RIJV) Cross-sectional Area (CSA) Pre- and Post-Valsalva	The change in cross-sectional area (CSA) of the right internal jugular vein (RIJV) pre- and post-Valsalva is a measurement of venous compliance and was determined noninvasively with Doppler ultrasound. An increase in RIJV CSA >17% during Valsalva effectively rules out elevated right atrial pressure (RAP) and suggests effective volume removal or decongestion. The difference between baseline and 1 month values of change in RIJV CSA are reported.	Up to 1 month (measured at baseline and 1 mo)
Fluid Balance	Strict intake (oral intake, intravenous medications, fluids, etc.) and output (urine, emesis, stools, drains, etc.) will be documented by the nurses on the HF floors per routine clinical protocol for all patients. Fluid balance will be determined by subtracting the volume of total intake from the volume of total output (in mL) over 24 hours (7 am to 7 am or the preceding 24-h period if no 7 am to 7 am period is available). Fluid balance and urine output will be ascertained by chart review daily during the intervention while the participants are hospitalized.	Daily while in hospital
Acute Kidney Injury	Acute kidney injury will be defined based a rise in Cr ≥0.3 mg/dL.	Daily while in hospital, 1 mo & 3 mos
Kansas City Cardiomyopathy Questionnaire (KCCQ) Clinical Score Change at 1 Month	The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a well-validated 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. For each domain, the validity, reproducibility, responsiveness and interpretability have been independently established. Scores are transformed to a range of 0-100, in which higher scores reflect better health status. A mean difference over time of 5 points on the KCCQ Overall Summary Scale reflects a clinically significant change in heart failure status. A 10 point decline in KCCQ scores has important prognostic significance in terms of survival.	Baseline to 1 month

SF-36 Mental Component Score (MCS) Change at 1 Month	The Medical Outcomes Study (MOS) 36-item Short-Form Health Survey (SF-36) is a well-validated generic HRQOL questionnaire that generates two composite scores: the Physical Component Score (PCS) and Mental Component Score (MCS). The PCS aggregates items from Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, and Social Functioning. The MCS aggregates items from Role-Emotional, Mental Health, General Health, Vitality, and Social Functioning. The mean for each summary scale is 50 points with standard deviation of 10 points. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability.	Baseline to 1 month

PHQ-9 Depression Index Change at 1 Month	The Patient Health Questionnaire (PHQ-9) Depression Index is a well-established index of depression and has been validated in many patient populations. Its scores range from 0-27 with increasing scores representing increasing depression severity. Score categories represent depression severity and management recommendations: 0-4 - Minimal or no depression. Monitor; may not require treatment. 5-9 - Mild. Use clinical judgment (symptom duration, functional impairment) to determine necessity of treatment. 10-14 - Moderate. Use clinical judgment (symptom duration, functional impairment) to determine necessity of treatment. 15-19 - Moderately severe. Warrants active treatment with psychotherapy, medications, or combination. 20-27 - Severe. Warrants active treatment with psychotherapy, medications, or combination.	Baseline to 1 month
PSQI Total Score Change at 1 Month	The Pittsburgh Sleep Quality Index (PSQI) is the most widely used global sleep assessment and has been studied in the renal transplant population. Consisting of 19 items, the PSQI measures several different aspects of sleep, offering seven component scores and one composite score. The component scores consist of subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication, and daytime dysfunction. Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality. Traditionally, the items from the PSQI have been summed to create a total score to measure overall sleep quality.	Baseline to 1 month
