Abstract

A computerized system and method comprises a predictive model for estimating the probability of a patient hospital readmission. The computerized system and method is useful for identifying patients at risk of hospital readmission and further identifying an intervention to mitigate the risk and reduce the likelihood that the patient returns to the hospital. The computerized system method collects and analyzes historical health data from administrative claims data and current health data collected in real-time from medical records at the point of treatment. Signals indicating readmission are extracted from the health data that is collected. The signals are evaluated by the model software application to estimate a probability that a patient will be readmitted to the hospital. Patients with a high readmissions probability score are selected for clinical programs and interventions that help them manage their health conditions and problems and reduce the likelihood that they return to the hospital.

First claim

1 - 7 . (canceled)

8 . A computerized system for reducing hospital admissions comprising:
(a) at least one computerized database storing for each of a plurality of inpatients patient data comprising:
(1) historical health data from administrative claims data for said inpatient;
(2) current health status data from at least one medical record for said inpatient;
(3) health condition data for one or more health conditions; and
(4) a plurality of readmission triggers to invoke application of a readmissions predictive model;
(b) a server executing programming instructions to:
(1) identify by said computer in said patient data at least one of said plurality of readmission triggers for a plurality of inpatients;
(2) apply by said server to said historical health data and said current health data said readmissions predictive model to calculate a readmission risk score for each of said plurality of inpatients, said readmissions predictive model evaluating at least one factor selected from the group consisting of: a number of days between previous and current admission, a Charlson Comorbidity Index, and an admission count within a specified period;
(3) compare by said server said readmission risk scores to a threshold score; and
(4) if said readmission risk score exceeds said threshold score, identify by said computer a subset of inpatients where wherein at least one clinician identifies for each of said inpatients:
(i) one or more health conditions for said inpatient; and
(ii) at least one intervention for said inpatient based on said one or more health conditions for said inpatient, said intervention comprising providing said inpatient with medication safety education and post-discharge counseling.

9 . The computerized system of claim 8 wherein said intervention is enrolling said inpatient in a chronic care management program.

10 - 11 . (canceled)

12 . The computerized system of claim 8 wherein said server applies said readmission predictive model in response to an online request.

13 . The computerized system of claim 8 wherein said server applies said readmission predictive model in connection with a batch of patient data.

14 . The computerized system of claim 8 wherein said server further executes said programming instructions in response to a readmissions trigger selected from the group consisting of an admission to a hospital or a discharge from a hospital.

15 . A computerized method for reducing hospital admissions comprising:
(a) receiving at a computer patient data for a plurality of inpatients to be discharged from an inpatient facility, said inpatients having one or more different health conditions, comprising:
(1) historical health data from administrative claims data for said each of said inpatients; and
(2) current health data from at least one medical record for each of said inpatients;
(b) defining at said computer a plurality of readmissions triggers to invoke application of a readmissions predictive model wherein said readmissions predictive model evaluates at least one factor selected from the group consisting of: a number of days between previous and current admission, a Charlson Comorbidity Index, and an admission count within a specified period; (c) identifying by said computer in said patient data at least one of said plurality of readmission triggers for a subset of said plurality of inpatients having one or more different health conditions; (d) applying by said computer to said patient data for each of said inpatients in said subset said readmissions predictive model; (e) receiving at said computer from said readmissions predictive model a readmission risk score for each of said inpatients in said subset; (f) comparing by said computer said readmission risk score for each of said inpatients in said subset to a threshold score; and (g) for each inpatient with a readmission score exceeding said threshold score, adding by said computer said inpatient to a list of inpatients and associated readmissions scores for review by a computer user; and (h) identifying for each patient on said list, an intervention that will reduce the risk score determined by said readmissions predictive model.

16 . (canceled)

17 . The computerized method of claim 15 further comprising identifying for each inpatient with a readmission risk score exceeding said threshold score an intervention.

18 . (canceled)

19 . The computerized method of claim 15 wherein receiving at a computer patient data comprises receiving said patient data in a batch of patient data.

20 . (canceled)

21 . The computerized method of claim 15 wherein said intervention comprises providing said inpatient with medication safety education and post-discharge counseling.
