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
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:
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
