Brak interwencji: Control Arm
Participants receive usual perioperative care with a placeholder blank display without the machine learning-derived acute kidney injury (AKI) risk score.
The clinical decision support tool remains hidden in the electronic health record, and no alerts or recommendations related to the study are shown.
|
|
|
Eksperymentalny: Acute Kidney Injury Risk Score Only
A machine learning-derived preoperative AKI risk score is displayed within the electronic health record for high-risk patients.
A passive recommendation indicating that the patient may benefit from a KDIGO-based kidney-protective bundle is provided.
The information is advisory only, and no interruptive alerts are used.
|
A non-adaptive, machine learning-based clinical decision support tool integrated into the electronic health record that generates a preoperative probability of acute kidney injury (AKI) using routinely collected patient data.
For patients identified as high risk, the tool displays the risk estimate to anesthesia providers without an accompanying Best Practice Advisory (BPA) recommending consideration of a KDIGO-based kidney-protective bundle.
The intervention is advisory only, does not mandate clinical actions, and is designed to support provider decision-making within the existing clinical workflow.

Eksperymentalny: Acute Kidney Injury Risk Score with Best Practice Advisory
The machine learning-derived AKI risk score is displayed within the electronic health record for high-risk patients, accompanied by an interruptive Best Practice Advisory (BPA) that notifies providers that the patient may benefit from a KDIGO-based kidney-protective bundle.
The alert is advisory only and does not mandate clinical actions.

Dilution Corrected KDIGO AKI measurement (Stage 1 or higher)
Ramy czasowe: AKI is defined per KDIGO as corrected creatinine increase ≥0.3 mg/dL within 48 hours or ≥1.5× baseline within 7 days. This measure captures "hidden AKI" - kidney injury masked by fluid dilution that would be missed using standard uncorrected creatinine.
|
Acute kidney injury (AKI) assessed using KDIGO creatinine criteria applied to dilution-corrected postoperative serum creatinine. Creatinine is corrected for hemodilution from perioperative fluid retention using the formula: Corrected Creatinine (mg/dL) = Measured Creatinine × (1 + Net Fluid Balance / Total Body Water) Where:
