October 8, 2019 updated by: Qi Qian, M.D., Mayo Clinic
The investigators are doing this research to investigate whether multifaceted preventive measures for newly hospitalized ventricular assist device (VAD) patients will reduce the Acute Kidney Injury (AKI) occurrence rate, progression and associated complications

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of the study is to investigate whether preventive measures for newly hospitalized ventricular assist device (VAD) patients will reduce the Acute Kidney Injury (AKI) occurrence rate, progression and associated complications

Participants will be in the study for the first 7 days of hospitalization. The study investigators will access the electronic medical record daily from admission day 1 through admission day 7 in order to provide clinical recommendations in an effort to minimize AKI risk as per routine practice.

If the patient is discharged prior to day 7 the study, intervention will be terminated on day of discharge.

The investigators will review the participant's medical record up to one year after surgery.

This study will not include any experimental laboratory tests or experimental medication.

The clinical recommendations will regard the following:

  1. Avoidance of potentially nephrotoxic medications (e.g. NSAIDs, intravascular contrast, nephrotoxic antimicrobials)
  2. Optimizing volume status (avoidance of volume overload or depletion)
  3. Optimizing electrolytes and acid-base status
  4. Optimizing hemodynamics (Mean arterial BP>65mmHg)
  5. Assessment of kidney function with serum creatinine and/or cystatin C None of the suggestions will be experimental. All suggestions will be based on standard nephrology practice.

The investigators plan to compare the results of the current study with those in in the years of 2012-2017 (1/7/2012- 1/7/2017) via retrospective chart review

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria:

Adult patients with VAD in place who are admitted to the hospital for acute medical illness during the study period. For those with multiple admissions during the study period only the first admission will be studied.

Patients who are able to give consent. In case of patients that are mentally impaired we will obtain consent from power of attorney and when patients regain intact mental capacity we will reobtain consent from the patient.

Exclusion criteria:

Patients on dialysis (hemodialysis or peritoneal dialysis).

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Rate of AKI in hospitalized VAD patients based on AKIN criteria
Time Frame: The first 7 days of hospitalization
The AKIN staging system has 3 stages: 1) serum creatinine increase ≥ 26.5 umol/L or increase to 1.5-2.0 fold from baseline, OR urine output <0.5 ml/kg/h for 6 h; 2) serum creatinine increase > 2.0-3.0 fold from baseline OR urine output <0.5 ml/kg/h for 12 h; 3) serum creatinine increase >3.0 fold from baseline OR serum creatinine ≥354 umol/l with an acute increase of at least 44 umol/l or need for Renal Replacement Therapy (RRT) OR urine output <0.3 ml/kg/h for 24 h OR anuria for 12 OR need for RRT

Severity of AKI based on AKIN stages (I, II, III) 1
Time Frame: The first 7 days of the hospitalization
The AKIN staging system has 3 stages: 1) serum creatinine increase ≥ 26.5 umol/L or increase to 1.5-2.0 fold from baseline, OR urine output <0.5 ml/kg/h for 6 h; 2) serum creatinine increase > 2.0-3.0 fold from baseline OR urine output <0.5 ml/kg/h for 12 h; 3) serum creatinine increase >3.0 fold from baseline OR serum creatinine ≥354 umol/l with an acute increase of at least 44 umol/l or need for Renal Replacement Therapy (RRT) OR urine output <0.3 ml/kg/h for 24 h OR anuria for 12 OR need for RRT
The first 7 days of the hospitalization

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: One year after hospitalization
The length of hospital stay will be determined from the electronic medical record.
One year after hospitalization
In hospital, 60 day and one-year mortality
