Systems and methods for medical data processing and analysis
First Claim
1. A method for treating a patient following a surgical procedure, the method comprising:
- inputting acute phase response (APR) biomarker data defining a level of an acute phase response (APR) biomarker in said patient at a succession of biomarker measurement times following said medical procedure, said APR biomarker data defining a biomarker time course representing an evolution over time of said acute phase response;
processing said APR biomarker data to determine a derivative with respect to time of said time course from said APR biomarker data to provide APR time series data, wherein said processing of said APR biomarker data to determine said derivative with respect to time of said time course further comprises correcting for a clearance rate of said biomarker in said patient;
identifying one or both of a maximum and a minimum in said APR time series data;
determining a value for an alert state variable responsive to said APR time series data; and
if the alert state variable has a first value then treating the patient for infection.

Abstract
We describe a method of predicting the response of a patient to a medical procedure, the method comprising: inputting acute phase response (APR) biomarker data defining a level of an acute phase response (APR) biomarker in said patient at a succession of biomarker measurement times following said medical procedure, said APR biomarker data defining a biomarker time course representing an evolution over time of said acute phase response; and processing said APR biomarker data to determine a derivative with respect to time of said time course from said APR biomarker data to provide APR time series data; determining a prediction of the response of said patient to said medical procedure from said APR time series data.

12. A medical system for treating a patient following a surgical procedure, the system comprising:
-
working memory; program memory; a processor coupled to said working memory and to said program memory; an input to receive APR biomarker data comprising data representing a level of an acute phase response (APR) biomarker in said patient at a succession of biomarker measurement times following said medical procedure, said APR biomarker data defining a biomarker time course representing an evolution over time of said acute phase response, said APR biomarker comprising CRP (C-Reactive Protein) and said APR biomarker data defining a level of CRP in the patient; and wherein said program memory stores processor control code to; process said APR biomarker data to determine a derivative with respect to time of said time course from said APR biomarker data to provide APR time series data, wherein said processing of said APR biomarker data to determine said derivative with respect to time of said time course further comprises correcting for a clearance rate of CRP in said patient; identify one or both of a maximum and a minimum in said APR time series data; determine a value for an alert state variable responsive to said APR time series data; and if the alert state variable has a first value then identify the patient for treatment for infection.
