Abstract

Systems useful for analyzing data related to clinical pathways and performing actions based upon the analyses. A self-analyzing system for suggesting default clinical pathways for various procedures. A self-analyzing system for suggesting deviation from a current clinical pathway and entry into an alternative clinical pathway based upon historical information about the results of actions. Statistical analysis systems based on clinical pathways. A rating system for care providers or proposed pathways based on historical information. Systems for gathering clinical pathway information. Systems for tracking clinical pathway outcomes based on data collected post-treatment. A system for prequalification for appropriate discharge and post-discharge handling of and communication with a new class of patient, those requiring stable acute care. A questionnaire computer language and subsystem are used in various stages of the systems of the invention. Corresponding methods are also disclosed.

Claims

1. A method for manipulation and analysis of data related to clinical pathways, the method comprising the steps of:

(a) providing a clinical pathway database for storing;

(i) an initial procedure decision data element, corresponding to a decision point within the clinical pathway; and

(ii) at least one subsequent decision data element, corresponding to an available subsequent decision point within the clinical pathway;

(iii) a patient identification data element corresponding to the initial and subsequent decision data elements for a particular patient;

(iv) at least one patient visit data element corresponding to the patient identification data element; and

(v) a time stamp data element corresponding to each of the at least one patient visit data elements;

(b) providing a historical clinical pathway database for storing previously selected subsequent decision data elements, selected corresponding to the initial procedure decision data element;

(c) selecting one of the at least one subsequent decision data elements stored within the clinical pathway database;

(d) comparing the selected subsequent decision data element, including the associated patient identification data element, patient visit data element and time stamp data element, with the previously selected subsequent decision data elements, including the associated patient identification data element, patient visit data element and time stamp data element, stored in the historical clinical pathway database; and

(e) based upon predetermined correlation criteria between the selected subsequent decision data element and the previously selected subsequent decision data elements stored in the historical clinical pathway database, modifying the at least one subsequent decision data element within the clinical pathway database.

2. A system for manipulation and analysis of data related to clinical pathways, comprising:

(a) a clinical pathway database for storing;

(i) an initial procedure decision data element, corresponding to a decision point within the clinical pathway;

(ii) at least one subsequent decision data element, corresponding to an available subsequent decision point within the clinical pathway;

(iii) a patient identification data element corresponding to the initial and subsequent decision data elements for a particular patient;

(iv) at least one patient visit data element corresponding to the patient identification data element; and

(v) a time stamp data element corresponding to each of the at least one patient visit data elements;

(b) a historical clinical pathway database for storing previously selected subsequent decision data elements, selected corresponding to the initial procedure decision data element; and

(c) processing means, including a storage device, for performing the steps of;

(i) selecting one of the at least one subsequent decision data elements stored within the clinical pathway database;

(ii) comparing the selected subsequent decision data element, including the associated patient identification data element, patient visit data element and time stamp data element, with the previously selected subsequent decision data elements, including the associated patient identification data element, patient visit data element and time stamp data element, stored in the historical clinical pathway database; and

(iii) based upon predetermined correlation criteria between the selected subsequent decision data element and the previously selected subsequent decision data elements stored in the historical clinical pathway database, modifying the at least one subsequent decision data element within the clinical pathway database.
