System and method for monitoring patient care
First Claim
1. A method, executed on a computing device, for facilitating management of patient care, the method comprising:
- building a cohort or event collection of interest by performing a series of steps, includingreceiving in the computing device data defining one or more events relating to the cohort or event collection, where each of the events is applicable to a plurality of patient records;
receiving in the computing device data specifying logical relationships between the one or more events;
composing a logical expression including the one or more events in accordance with the relationships, where the logical expression relates to a clinical question of a user;
receiving in the computing device data specifying a limiting condition on the logical expression, said specified limiting condition includingat least one calendar time period relating to at least one of the one or more events, andone of inclusion and exclusion of at least one of the one or more events within a time interval, said at least one event having a specified temporal relationship to a start time or to another event;
accessing a computer-readable memory storing a database of patient records;
identifying patient records in the database consistent with the logical expression;
including in a set of patient records, for each patient having at least one of said identified patient records consistent with the logical expression, eitheronly one of said identified patient records for each patient, said set of patient records then being characterized as a cohort, orall of said identified patient records for each patient, said set of patient records then being characterized as an event collection, andlabeling said set of patient records as a cohort or an event collection;
performing a query on said set of patient records for the cohort or event collection to yield a query result, the query including the clinical question; and
generating a report including the query result,whereinsaid defining is performed via a first portion of a user interface executing on said computing device affording a user access to data for defining the events,the limiting condition is specified via a second portion of the user interface, andthe label of the cohort or event collection is displayed on a third portion of the user interface, affording the user access to a definition of the cohort or event collection.

Abstract
Systems and methods are provided for facilitating management of health care in medical facilities such as hospitals, clinics, emergency rooms, etc., for example by monitoring and assessing the quality of patient care. Data is collected and operated on relating to medical conditions, treatment, cost, care, events, outcomes and results of treatments, and data representing the collective experience of similar patients is mined to discover opportunities to improve the quality of health care. Statistical and comparative data and reports including such and other information indicate a quality of care and provide epidemiologically cogent information. Quality of care may be considered as achieving desired or expected norms of performance, including success, in a timely fashion, and can be judged not just by what functionally happens during a patient instigated encounter, but also by long term outcomes evidenced by the patient'"'"'s passage through the health care delivery system.

8. A user interface, displayed on a display device, for organizing a query related to patient care, the query including a clinical question, the user interface comprising:
-
a first portion configured to display user definitions of one or more events relating to a cohort or event collection of interest and applicable to a plurality of patient records, and a logical expression including the one or more events and relating to the clinical question; a second portion configured to display a user-specified limiting condition on the logical expression, said specified limiting condition including at least one calendar time period relating to at least one of the one or more events, and one of inclusion and exclusion of at least one of the one or more events within a time interval, said at least one event having a specified temporal relationship to a start time or to another event; and a third portion configured to display a user-specified label of at least one set of patient records, the label indicating that the set is either a cohort or an event collection, wherein the at least one set of patient records is identified based on at least the logical expression and the limiting condition on the logical expression; and wherein an event collection includes all patient records consistent with the logical expression, and a cohort includes, for a given patient, only one patient record consistent with the logical expression. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system for evaluating patient care, comprising:
-
a user input device and display; a database of patient data; and a server configured to provide a user interface accessible by the user at the user input device, the user interface having a first portion configured to display user definitions of one or more events relating to a cohort or event collection of interest and applicable to a plurality of patient records, and a logical expression including the one or more events and relating to a clinical question of the user; a second portion configured to display a user-specified limiting condition on the logical expression, said specified limiting condition including at least one calendar time period relating to at least one of the one or more events, and one of inclusion and exclusion of at least one of the one or more events within a time interval, said at least one event having a specified temporal relationship to a start time or to another event; and a third portion configured to display a user-specified label of at least one set of patient records, the label indicating that the set is either a cohort or an event collection, wherein an event collection includes all patient records consistent with the logical expression, and a cohort includes, for a given patient, only one patient record consistent with the logical expression, wherein the at least one set of patient records is identified based on at least the logical expression and the limiting condition on the logical expression; provide access to the database of patient data, perform a query on the patient data for the cohort or event collection to yield a query result, the query including the clinical question, and generate a report including the result of the query, in accordance with a request from the user. - View Dependent Claims (15, 16, 17, 18, 19, 20)
