Prediction of acute kidney injury from a post-surgical metabolic blood panel
Systems and methods are provided for predicting the likelihood of acute kidney injury. An input interface is configured to receive a plurality of features derived from the results of a post-surgical metabolic blood panel and either a pre-surgical metabolic blood panel or a perisurgical metabolic blood panel. A predictive model is configured to calculate a parameter representing a likelihood of acute kidney injury from the plurality of features. A user interface is configured to provide the calculated parameter to a user in a human comprehensible form.
1. A method for predicting the likelihood of acute kidney injury comprising:
receiving a plurality of features derived from the results of a post-surgical metabolic blood panel and one of a pre-surgical metabolic blood panel and a perisurgical metabolic blood panel at an input interface associated with a predictive model;
calculating a parameter representing a likelihood of acute kidney injury from the plurality of features via the predictive model, each of the input interface and the predictive model being implemented as machine executable instructions stored on a non-transitory computer readable medium and the plurality of features including a difference in a creatinine level between the one of the pre-surgical metabolic blood panel and the perisurgical metabolic blood panel and the post-surgical blood panel divided by a time elapsed between a surgery and the post-surgical metabolic blood panel; and
providing dialysis to the patient if the calculated parameter is within a range associated with a severe risk of acute kidney injury.
2. The method of claim 1 , wherein the plurality of features includes a sodium level from the post-surgical metabolic blood panel.
3. The method of claim 1 , wherein the plurality of features includes a potassium level from the post-surgical metabolic blood panel.
4. The method of claim 1 , wherein the plurality of features includes a bicarbonate level from the post-surgical metabolic blood panel.
5. The method of claim 1 , wherein the plurality of features includes an albumin level from the post-surgical metabolic blood panel.
6. The method of claim 1 , wherein the plurality of features includes a difference in a blood urea nitrogen level between the one of the pre-surgical metabolic blood panel and the perisurgical metabolic blood panel and the post-surgical blood panel.
7. The method of claim 6 , wherein the difference in the blood urea nitrogen level is divided by a time elapsed between a surgery and the post-surgical metabolic blood panel.
8. A method for predicting the likelihood of acute kidney injury comprising:
receiving a plurality of features derived from the results of a post-surgical metabolic blood panel and one of a pre-surgical metabolic blood panel and a perisurgical metabolic blood panel at an input interface associated with a predictive model;
calculating a parameter representing a likelihood of acute kidney injury from the plurality of features via the predictive model, each of the input interface and the predictive model being implemented as machine executable instructions stored on a non-transitory computer readable medium and the plurality of features including a difference in a blood urea nitrogen level between the one of the pre-surgical metabolic blood panel and the perisurgical metabolic blood panel and the post-surgical blood panel divided by a time elapsed between a surgery and the post-surgical metabolic blood panel; and
providing treatment to the patient if the calculated parameter is within a range associated with a severe risk of acute kidney injury.
9. The method of claim 8 , wherein the change in the blood urea nitrogen level is normalized by a time elapsed between a surgery and the post-surgical metabolic blood panel.
