DESCRIPTION OF A PREFERRED EMBODIMENT

[0024] In brief overview and referring to FIG. 3, a system constructed in accordance with the present invention includes a computer or processor 10 having a rules engine in communication with a records management database 14, an input device 15, and an output display 18, which may generate printed reports. Patient encounters are input to the system through the input device 14. To generate a report, the processor 10 executes the rules of the rules engine that accesses the patient database 14 to generate a report through the output device 18.

Structure

[0025] The present invention is based on structured descriptive data items. Such data includes but is not limited to past medical history, current medications, exam findings, diagnoses, treatments, lab results, and severity assessments. Descriptive data items may be linked together with other descriptive data items. Each data item can be further “tagged” with additional codes. A non-limiting list of standards for the descriptive data items which the system can tag with additional metadata is shown in Table 1.

TABLE-US-00001 TABLE 1 Past Medical History SNOMED Social History SNOMED Problem List SNOMED, ICD9/10 Medications, Prescriptions RxNorm, SNOMED Lab Orders/Results LOINC, SNOMED HPI/Chief Complaint SNOMED, LOINC, Metathesaurus Diagnoses ICD9/10, SNOMED, Metathesaurus Morphologies SNOMED Exam SNOMED, LOINC, Metathesaurus Procedures SNOMED, LOINC, Metathesaurus

[0026] These descriptive data items include, but are not limited to: the general standard elements, the Systemized NOmenclature of MEDicine (SNOMED) which includes codes for medical history, social history, problem list, medications and prescriptions, laboratory orders and laboratory results, history of present illness (HPI) and chief complaint, diagnoses, morphologies, examinations and procedures; the laboratory standard, Local Observation Identifier for Names and Codes (LOINC) which includes laboratory orders and laboratory results, history of present illness (HPI) and chief complaint, examinations and procedures; the catalog of standard drug and drug delivery device names (RxNORM) for medications and prescriptions; the International Classification of Disease (ICD(n)) where (n) is the number of the present edition, which describes the problem list and diagnoses; and the Metathesaurus, a multi-lingual vocabulary database that provides alternative names to the same concepts for history of present illness (HPI) and chief complaint, diagnoses, examinations and procedures.

[0027] In one embodiment, the system uses an XML-based markup language to create the structured data system. However, other languages and schema may be used.

[0028] An example of a rule is shown for a foot examination:

TABLE-US-00002 <mm:examBullet examElement=“foot inspection, sensation by monofilament, pedal pulses palpated” renderElementSelf=“true” isBodyLocation=“true” tabLabel=“Diabetic Foot”> <mm:descriptiveCoding> <mm:descriptiveCodingItem codeSystem=“SNOMED” codeValue=“164480009” codeName=“On examination - foot (finding)”/> <mm:descriptiveCodingItem codeSystem=“SNOMED” codeValue=“134388005” codeName=“Monofilament foot sensation test”/> <mm:descriptiveCodingItem codeSystem=“SNOMED” codeValue=“91161007” codeName=“Pedal pulse taking”/> </mm:descriptiveCoding> </mm:examBullet>

[0029] In this example, the user enters data or facts (such as age, body temperature, etc.) about a specific object (such as a patient, body part, etc.) into the system relating to a specific exam performed. The system associates those facts and relative descriptive data items with the specific object. The rules engine examines all the facts associated with a specific object and determines if the fact associated with the object matches with any of the descriptive data items that are present in the database. If so, the engine then determines if those matching data items should be applied to the fact as metadata about the fact. The rules engine then includes the metadata tags for the appropriate codes.

[0030] The rules engine examines a set of facts about an object, and while examining those facts, applies a hierarchical tree of rules to the metadata tags added to those facts to determine if the set of facts meets the requirements of any of the defined rules. If a set of facts matches the rules, the rules engine uses the metadata attached to those facts to determine the outcome value of the specific rule. This outcome value is associated to the object to which the fact applies. Also, rules can generate an output value based on the outcome of other rules. Reports may be generated in real time by applying rules to objects and the facts associated with the objects.

[0031] In a second example, the results of the administration of a drug during the encounter are included. In this example, a flu vaccine was recommended but the patient declined, instead opting to have the vaccine administered at a later time and location:

TABLE-US-00003 <mm:var name=“influenzaImmunization” type=“select” label=“PQRS 110: Preventive Care and Screening: Influenza Immunization” stickyValues=“false” tabLabel=“Details”> <mm:varOption value=“n/a” isDefault=“true”/> <mm:varOption value=“Influenza Immunization Administered during Influenza season”> <mm:descriptiveCoding> <mm:descriptiveCodingItem codeSystem=“Metathesaurus” codeValue=“C2959021” codeName=“PATIENT DOCUMENTED TO HAVE RECEIVED INFLUENZA VACCINATION DURING INFLUENZA SEASON”/> </mm:descriptiveCoding> </mm:varOption> <mm:varOption value=“Influenza Immunization previously received during influenza season”> <mm:descriptiveCoding> <mm:descriptiveCodingItem codeSystem=“Metathesaurus” codeValue=“C2959021” codeName=“PATIENT DOCUMENTED TO HAVE RECEIVED INFLUENZA VACCINATION DURING INFLUENZA SEASON”/> </mm:descriptiveCoding> </mm:varOption> <mm:varOption value=“Influenza Immunization not Administered for Documented Reasons.” > <mm:descriptiveCoding> <mm:descriptiveCodingItem codeSystem=“Metathesaurus” codeValue=“C1718261” codeName=“Reason influenza virus vaccine not received”/> </mm:descriptiveCoding> </mm:varOption> <mm:varOption value=“Influenza Immunization Ordered or Recommended, but not Administered” > <mm:descriptiveCoding> <mm:descriptiveCodingItem codeSystem=“Metathesaurus” codeValue=“C3248434” codeName=“INFLUENZA IMMUNIZATION ORDERED OR RECOMMENDED (TO BE GIVEN AT ALTERNATE LOCATION OR ALTERNATE PROVIDER); VACCINE NOT AVAILABLE AT TIME OF VISIT”/> </mm:descriptiveCoding> </mm:varOption> <mm:varOption value=“Influenza immunization was not ordered or administered, reason not given”/> </mm:var>

[0032] In this system, the provider is not entering any data he or she would not normally enter to document a patient encounter. That is, no additional questions are requested by the system. The system's rules automatically populate using the data in the patient database.

[0033] Any data item can be tagged. Further, because the structured data is extremely detailed, the system can differentiate the nuances in metadata tagging. For example, the system not only knows if a provider recorded a pain intensity level, but what the specific level was. This level of detail is required for an automated quality measure calculation to take place.

[0034] To perform the calculation, the system organizes each quality measure in terms of its numerator and denominator questions (FIG. 4). Each quality measure 48 includes a set of attributes 50 and a set of denominator 54 and numerator 58 questions in a hierarchical tree. The logic block 62 permits sets of logic to be used together. Thus, a single question will have logic to determine if it is true or false. The logic takes the form of either discrete calculated data or a coded logic “block.” In one embodiment, the block is coded in JavaScript. The calculated data permits the expression of the following types of logic: Find All, Find Any, Exclude All, Exclude Any. Each of these expressions behaves in a different way and can be used in combination to express the desired logic. Each of these expressions contains a 0-to-many list of descriptive codes (metadata) to compare with (FIG. 5). If the logic finds a match, it returns “true” and then logic block will branch to the follow-up “if true section” and process any follow up questions. The same is also the case with the “false” branch. At each question and follow-up question, CPT-codes and modifiers can be calculated and added to the overall quality measure. This format allows for logic to be chained together for computing all of the variability needed for the variety of quality measure calculations.

[0035] Considering an example in which a patient is counseled about smoking and referring to FIG. 6, the patient begins the visit (Step 1) and the user enters whether the patient is a new patient (Step 104). If the patient is not a new patient, the visit begins (Step 108). If the patient is a new patient initial data is collected about the patient such as age (Step 112) and insurance plan (Step 116), at which point the system determines whether a quality measure calculation will be performed on this patient based on age and insurance, at which point the visit begins (Step 108).

[0036] The patient is asked whether he or she is a smoker and if the answer is “no,” the remainder of the examination take place (Step 124). If the answer is “yes,” the fact is entered into the database as “smoker” and assigned the SNOMED code 77176002 by the system. The clinician then counsels the patient about the health effects of smoking and the system enters the SNOMED code for “smoking cessation education” 225323000 into the database and the examination proceeds.

[0037] Upon completion of the visit (Step 124), the system processes the examination findings, diagnosis, and treatment data records stored in the database, and uses the coded metadata to validate patient eligibility and determine the correct quality codes.

[0038] Referring to FIG. 7, the system determines the eligibility of the patient for a quality measure calculation by examining the data about the patient. The system first considers whether the patient is covered by Medicare (Step 130), if the answer is no the patient is determined to be ineligible (Step 134). If the patient is covered by Medicare, the system then determines if the patient is over 18 years old (Step 138). If the patient is not over 18 years old, the patient is again found to be ineligible (Step 134). If the patient is over 18 years old the patient is eligible for a quality measure calculation.

[0039] The system determines whether the patient is a smoker (Step 146) and if the answer is “no” the CPT value is set to “no” (Step 150). If the patient is a smoker, the system determines if the counseling was performed (Step 154). If the answer is “no,” CPT is set to “fail” and if the answer is “yes,” the CPT is set to “pass” step 160. The system will also generate information to the user as to why an entry is a “fail” and what can be done to correct it.

[0040] As an example, a quality measure for this scenario has the structure:

TABLE-US-00004 <xmlMeasure pqrsNumber=“226” title=“Preventive Care and Screening: Tobacco Use: Screening and Cessation Intervention” pqrsDomain=“COMMUNITY_POPULATION_HEALTH” reportingPeriod=“EACH_VISIT”> <xmlDenominator> <xmlQuestionAliases> <xmlQuestionAlias questionAlias=“medicarePartB”/> <xmlQuestionAlias questionAlias=“patientGreaterEqualThan18”/> <xmlQuestionAlias questionAlias=“tobaccoByEncounter”/> </xmlQuestionAliases> </xmlDenominator> <xmlNumerator> <xmlQuestionAliases> <xmlQuestionAlias questionAlias=“tobaccoScreenedSmokerNegative”/> </xmlQuestionAliases> </xmlNumerator> </xmlMeasure>

[0041] with the denominator question having the structure:

TABLE-US-00005 <xmlQuestion questionAlias=“tobaccoByEncounter” questionText=“Is there an encounter code?”> <xmlLogicForTrue> <xmlFindAny> <xmlDescriptiveCoding> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90791”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90792”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90832”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90834”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90837”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90839”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“90845”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“92002”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“92004”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“92012”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“92014”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“96150”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“96151”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“96152”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“97003”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“97004”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99201”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99202”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99203”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99204”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99205”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99212”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99213”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99214”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99215”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99406”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“99407”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“G0438”/> <xmlDescriptiveCodingItem codeSystem=“CPT” codeValue=“G0439”/> </xmlDescriptiveCoding> </xmlFindAny> </xmlLogicForTrue> </xmlQuestion>

[0042] and the numerator having the structure:

TABLE-US-00006 <xmlQuestion questionAlias=“tobaccoScreenedSmokerNegative” questionText=“Was the patient screened for tobacco and is not a smoker?” cptCode=“1036F” performance=“pass”> <xmlLogicForTrue> <xmlFindAny> <xmlDescriptiveCoding> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“8517006” codeName=“Ex-smoker”/> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“266919005” codeName=“Never smoked tobacco”/> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“266927001” codeName=“Tobacco smoking consumption unknown”/> </xmlDescriptiveCoding> </xmlFindAny> </xmlLogicForTrue> <xmlFollowUpIfFalse> <xmlQuestionAliases> <xmlQuestionAlias questionAlias=“tobaccoScreenedSmokerPositive”/> </xmlQuestionAliases> </xmlFollowUpIfFalse> </xmlQuestion> <xmlQuestion questionAlias=“tobaccoScreenedSmokerPositive” questionText=“Was the patient screened for tobacco and is a smoker?” cptCode=“4004F” performance=“pass”> <xmlLogicForTrue> <xmlFindAny> <xmlDescriptiveCoding> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“77176002” codeName=“Smoker”/> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“428041000124106” codeName=“Occasional tobacco smoker”/> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“428071000124103” codeName=“Heavy tobacco smoker”/> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“428061000124105” codeName=“Light tobacco smoker”/> </xmlDescriptiveCoding> </xmlFindAny> <xmlFindAll> <xmlDescriptiveCoding> <xmlDescriptiveCodingItem codeSystem=“SNOMED” codeValue=“225323000” codeName=“Smoking cessation education”/> </xmlDescriptiveCoding> </xmlFindAll> </xmlLogicForTrue> <xmlFollowUpIfFalse> <xmlQuestionAliases> <xmlQuestionAlias questionAlias=“tobaccoNotScreenedMedicalReason”/> </xmlQuestionAliases> </xmlFollowUpIfFalse> </xmlQuestion>

[0043] With this structure, as the provider is entering data, the system collects all of the tagged metadata appropriate for this patient and encounter, and uses it for the measure calculation.

[0044] In overview, using the above example, when the system computes measure 226 of the quality measures which relates to Tobacco Screening and Cessation, the system first examines the inclusion criteria for the quality measure. All denominator requirements in a logic group must be met for the patient to be included in the calculation. In this example, the system ensures that the patient is Medicare Part B, over the age of 18, and has an encounter (CPT) code for an exam. If the inclusion criteria are met, then the system computes the numerator.

[0045] In this example, the numerator logic begins by looking for SNOMED codes that would indicate if the patient was screened for tobacco use or was not a smoker. If the system finds the presence of any of the SNOMED codes included in the Find Any logic block, then the system will return the corresponding CPT (in this case, code 1036F). There are no follow-up questions defined if the logic returns “true,” and in that case, the measure calculation is complete. If the logic returns “false” (meaning none of the SNOMED codes were found), the system will execute the question logic found in the follow-up “false” block. In this case, it would look for an alternative set of SNOMED codes and return the appropriate CPT codes and modifiers down the chain.

Results

[0046] Because the calculations are made in real-time, the quality measure can be displayed as the data are entered. In one embodiment, the display screen is shown in FIG. 8. In one embodiment, each entry is an active link. Clicking on the link displays how the calculation was made. In addition to real-time display, the system in one embodiment will generate a report on a specific entry (FIG. 9), as well as one that includes a summary breakdown by measure of the CPT codes and the percentage of measures transmitted (FIG. 10). Active links in each screen allow the provider to sort and filter information by measure, date, performance, and transmission status and override the automated measure calculation from these screens. By linking down to a specific visit for a patient, the provider can see the automated results and optionally override measures.
