|Contrast-induced Nephropathy||Other: Exposure to CBCIN risk score|
This is a case-control series comparing a strategy using a computer-based contrast induced nephropathy (CBCIN) risk tool in patients undergoing PCI versus usual care. Only inpatients will be included in this study. These inpatients will be compared to historical controls obtained using the medical record of age- and gender-matched inpatients who underwent cardiac catheterization with at least two consecutive daily post-procedure creatinine values. The percentage PCI will be matched in the retrospective series.
In the prospective group, the operator will be exposed to the CBCIN risk tool before and during care delivery with estimated CIN risk. The CBCIN risk tool estimates CIN risk based on the status of known risk factors (and suggests an associated standard hydration strategy based on left-ventricular end-diastolic pressure), which are automatically prepared from the patient's Electronic Medical Record and presented to the operator for review. This functionality has been evaluated in previous research and was found to be stable and reliable. Based on the data presented by and reviewed in the CBCIN risk tool, the operator may use the information and adjust therapy as clinically indicated (i.e. the risk tool is not the basis for clinical decisions). Following the PCI, serum creatinine will be measured as per treating physician, but those who undergo at least two consecutive daily serum creatinine measurements starting the day after the procedure will be included in the study. These patients will be called 6 months and 12 months post-procedure to determine mortality and re-hospitalization status.

Prospectively, inpatients undergoing percutaneous coronary intervention (PCI) will be consented, and the computer-based contrast induced nephropathy (CBCIN) risk score will be calculated and displayed to the operator, along with suggested standard CIN-avoidance strategies during the PCI. Following the PCI, serum creatinine will be measured as per treating physician, but those who undergo at least two consecutive daily serum creatinine measurements starting the day after the procedure will be included in the study. These patients will be called 6 months and 12 months post-procedure to determine mortality and re-hospitalization status.
Other: Exposure to CBCIN risk score
The computer-based contrast induced nephropathy (CBCIN) risk score and associated standard hydration strategy will be displayed on a monitor in front of the treating interventional cardiologist during the entirety of the PCI case. Since this scoring system and hydration strategy are both available in the peer-reviewed literature, clinical use of these data and implementation of a CIN-avoidance strategy is not experimental; however, the display of these data to interventional cardiologists is experimental. Based on exposure to these data, the treating interventional cardiologist may use the information as clinically appropriate (i.e. it is not the basis for clinical decisions).
Retrospectively, inpatients who underwent PCI and had at least two consecutive daily serum creatinine measurements will be selected. These patients will then be matched to the prospective patients, and matched by age and gender. Baseline CBCIN score will be calculated and other demographic and outcomes information will be obtained from medical records review.
- Development of CIN [ Time Frame: up to 4 days ]increase in serum creatinine of ≥0.3 mg/dL or ≥50% from the value before the procedure to the highest post-procedure value on days 1-4
