The present invention is generally directed to quantifying a confidence measurement for an impairment rating arising from a worker's compensation event. More specifically, the present invention is directed to a method and system for providing a confidence measurement for an impairment rating arising from gaps or omissions within an entered clinical data set.
The impairment rating process involves a clinician examining an injured worker for functional deficiencies as a result of a work related injury event. One or more administrative rule sets (ARSs) based on the injury event guide the clinician through the examination process. The accuracy and the quality of a resultant impairment rating is directly dependent on the compliance of the clinician to the ARS for the injury event. The method and description of the ARSs are described within the U.S. patent application Ser. No. 14/996,067 (the '067 Application), which is hereby incorporated by reference.
A lack of compliance and/or rigor to the impairment rating process can arise from numerous causes. For example, the clinician may not have adequate training and unintentionally omit certain measurements or neglect to examine for other critical pathology. Alternatively, the clinician may be so experienced that the initial examination and discussion with the injured worker cause a subjective jump to an impairment rating without an appropriate and complete examination and clinical data to support for the assumed or estimated impairment value. Additionally, the clinician may not have an appreciation of the need for data replication to obtain a statistical confidence in the measurement. Further, the clinician may be time limited and unable to perform a proper examination. Moreover, a perceived cost of the proper examination my may be thought too expensive for the necessary level of pathology.
Additionally, the clinician may see one or more sections of the ARS as a loophole, excessive, confusing, or clinically cumbersome. Regardless of the reason for non-adherence to one or more of the ARSs by omitting a section of the data set used for an impairment rating, the clinician may output an impairment rating value that significantly alters the worker's compensation claim.
There are also numerous reasons why a clinician may not perform the examination to the appropriate rigor, including intentional misrepresentation of the functional deficiencies. The clinician may also inadvertently, not paying attention, enter incorrect values. These causes have been described in the '067 Application and are also incorporated by reference herein. Errors by the clinician administrating the ARS and the impairment rating process are carried forward in the worker's compensation process and a resultant maximal medical improvement (MMI) of the injured individual. Thus, small errors within the impairment rating process can translate to larger issues over time. Cost, the need for prophylactics and braces, retraining, compensation claims, and legal costs from challenged ratings can grow based on small errors in the process. Stake holders such as employers, insurance companies, clinics and the injured worker rely of the accuracy and quality of a completed data set and a proper impairment rating.
The present invention is directed to calculating a deficiency analysis that provides a percentage of missing data for an impairment rating based on an observed data set. Comparing an observed data set with an ideal data set based on one or more administrative rule sets for an injury event allows one or more stakeholders within the workers compensation process to obtain a risk score and/or deficiency report for the observed data set and the resulting impairment rating. One or more risk scores and/or deficiency reports can be used to track quality and consistency of a clinician and quality and consistency across a medical provider network. After a risk score for an impairment rating is output, the risk score can be uploaded to a historical evaluation database for a percentile creation against other reports of similar body systems.
In one aspect, a method of calculating a risk score for an impairment rating in a worker's compensation claim comprises performing one or more tests on an injured worker to obtain an observed data set, uploading the observed data set to an administrative rule set database, comparing the observed data set to an ideal data set for the injury, wherein the ideal data set is determined according to the administrative rule set for the injury and based on a comparison of the observed data set to the ideal data set, outputting a risk score for the impairment rating. In some embodiments, the impairment rating comprises a maximum medical improvement. In some embodiments, the risk score is uploaded to a historical evaluation database for the creation of a percentile score based on one or more additional risk scores for similar body systems. In some of these embodiments, the percentile score created is based on a comparison to risk scores across all providers that have performed a similar exam. In further embodiments, the percentile score is created based on a comparison to risk scores of medical providers for the same specialty that have performed a similar exam. In some embodiments, the percentile score is created based on a comparison to risk scores of one or more doctors for a specific employer that have performed a similar exam. In some embodiments, the percentile score is created based on a comparison to risk scores of medical providers used by a specific insurance company that have performed a similar exam. In further embodiments, the percentile score is created based on a comparison to risk scores of risk scores of medical providers within a specific area that have performed a similar exam. In further embodiments, the percentile score is created based on a comparison to risk scores of medical providers within a specific zip code that have performed a similar exam.
In another aspect, a system for calculating a risk score for an impairment rating comprises an observed data set input configured to receive one or more observed data values of an observed data set, an administrative rule set database configured for receiving the observed data set and comparing the observed data set to an ideal data set for the injury, wherein the ideal data set is determined according to an administrative rule set for the injury and an impairment rating output, wherein the impairment rating output is configured to output a risk score for an impairment rating based on a comparison of the observed data set with the ideal data set. In some embodiments, the impairment rating comprises a maximum medical improvement. In some embodiments, the administrative rule set database comprises a HIPAA compliant database. In some embodiments, the system comprises a historical evaluation database configured to compare the risk score to one or more additional risk scores for similar body systems. In some embodiments, based on the comparison of the risk score to the one or more additional risk scores for similar body systems, a percentile score for the impairment rating is created. In some of these embodiments, the percentile score is created based on a comparison to risk scores of medical providers for the same specialty that have performed a similar exam. In some embodiments, the percentile score is created based on a comparison to risk scores of one or more doctors for a specific employer that have performed a similar exam. In further embodiments, the percentile score is created based on a comparison to risk scores of medical providers used by a specific insurance company that have performed a similar exam. In some embodiments, the percentile score is created based on a comparison to risk scores of risk scores of medical providers within a specific area that have performed a similar exam. In further embodiments, the percentile score is created based on a comparison to risk scores of medical providers within a specific zip code that have performed a similar exam.
In a further aspect, a method of creating one or more percentile scores based on one or more additional risk scores for similar body systems comprises uploading a risk score for an impairment rating to a historical evaluation database, comparing the risk score to one or more additional risk scores for similar body systems and based on the comparison of the risk score to the one or more additional risk scores for similar body systems, creating a percentile score for the impairment rating. In some embodiments, the percentile score is created based on a comparison to risk scores across all providers that have performed a similar exam. In some embodiments, the percentile score is created based on a comparison to risk scores of medical providers for the same specialty that have performed a similar exam. In further embodiments, the percentile score is created based on a comparison to risk scores of one or more doctors for a specific employer that have performed a similar exam.

Reference will now be made in detail to implementations of a method of and system for providing a confidence measurement in the impairment rating process as illustrated in the accompanying drawings. The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts. In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions can be made in order to achieve the developer's specific goals, such as compliance with application and business related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.
Referring now to
In some embodiments, the risk score equals the percentage of data missing from the observed data set as determined by the ARSs and the ideal data set for the injury. In some embodiments the risk score may indicate that the clinician has failed to sufficiently replicate measurements and/or failed to take ancillary measurements. For example, ancillary measurements mean that if a worker has injured a left shoulder (injured shoulder) then the right shoulder (healthy shoulder) must also be measured to evaluate a worker's baseline function. If the clinician fails to take this and/or other measurements then this will show up in the risk score for the impairment rating. Non-compliance to the necessary rigor of a clinical data set required by the ARSs can lead to potential error and/or lack of confidence in the impairment rating value.
The risk score and/or deficiency analysis for the impairment rating provides a percentage of missing data within the observed data set. For example, the percentage of missing data that is necessary to support a comprehensive impairment rating and report. A zero percent risk score or deficiency report indicates that all ratable data has been provided for the impairment report and the one or more stakeholders can have confidence in the report. In some embodiments, the method enables the ability to assign confidence quintiles to a report and grade the quality of a data set A+ through F−. In some embodiments, the data set is graded on a five star rating system. Ultimately, the risk score or deficiency analysis designates a confidence rating in the impairment rating provided by the clinician and not the output. The risk score and/or deficiency analysis analyzes the quality of the data that the clinician has used to support the impairment rating. In some embodiments, the impairment rating comprises a maximum medical improvement.
In some embodiments, after the risk score for the impairment rating is output, the risk score is then uploaded to a historical evaluation database for a percentile creation against other reports of similar body systems. For example, such as shown within
After receiving the observed data set, the administrative rule set database 215 compares the observed data set to an ideal dat set for the injury. As described above, the ideal data set assumes that all ARSs have been followed and correct values within the right and/or expected ranges have been entered. Based on a comparison of the observed data set to the ideal data set, a risk score for the impairment rating is created within a data deficiency report 225 where it can be viewed by one or more interested stakeholders. As described above, in some embodiments, the risk score equals the percentage of data missing from the observed data set as determined by the ARSs and the ideal data set for the injury. In some embodiments, the impairment rating comprises a maximum medical improvement.
As further shown within
As further shown within
Utilizing both of the DRE and the ROM methods allows a fairer, more accurate, reproducible and more complete analysis of the claimed medical conditions by using specific input analysis of digitized data for the spine including subjective complaints, functional measurements, static measurements, and diagnostic testing. As a result, each method (DRE and ROM) are simultaneously considered, compared, rated for WPI. Consequently, a determination is possible for first, the most accurate rating method representation, followed by a selection of the highest WPI value if both conditions are equally represented by the data. As shown within
Based only on the impairment rating report the treating clinician and the case management of the treating clinician has correctly healed the worker, with no further impairment and a rating of 0% WPI.
In some embodiments, the report 320 comprises the name of the treating physician 321, the date of the report 323, the injured body system 325 and the body part 325. However, the report 320 is able to comprise more or less information as appropriately desired. As shown within
As described above, the risk score and/or deficiency report provides a percentage of missing data. For example, the percentage of missing data that is necessary to support a comprehensive impairment rating and report. A zero percent risk score or deficiency report indicates that all ratable data has been provided for the impairment report and the one or more stakeholders can have confidence in the report. In some embodiments, the method enables the ability to assign confidence quintiles to a report and grade the quality of a data set A+ through F−. Ultimately, the risk score or deficiency analysis designates a confidence rating in the impairment rating provided by the clinician and not the output. Thus, while the impairment rating report such as described within
Based on the deficiency report 320, the treating clinician has not properly followed all applicable ARSs for the injured individual. Thus, it is likely that the treating physician needs to complete further learning and/or training to properly adhere to the ARSs for the injury. Particularly, as described above, the risk score equals the percentage of data missing from the observed data set as determined by the ARSs and the ideal data set for the injury. The risk score may indicate that the clinician has failed to sufficiently replicate measurements and/or failed to take ancillary measurements. If the clinician fails to take this and/or other measurements then this will show up in the risk score for the impairment rating. Non-compliance to the necessary rigor of a clinical data set required by the ARSs can lead to potential error and/or lack of confidence in the impairment rating value. In an embodiment, a personalized online playlist of one or more educational modules can be generated for training the treating physician to adhere to the ARSs for the injury. The one or more educational modules may be ordered according to respective scores associated with the deficiencies found in the impairment rating report. The personalized online playlist may be included in the deficiency report 320.
In operation, comparing an observed data set with an ideal data set based on one or more ARSs for an injury event allows one or more stakeholders within the workers compensation process to obtain a risk score and/or deficiency report for the observed data and the resulting impairment rating. One or more risk scores and/or deficiency reports can be used to track quality and consistency of a clinician and quality and consistency across a medical provider network.
Additionally, the risk score or deficiency analysis can be used for one or more stakeholders such as an account administrator or other stakeholder to track consistency of outcomes across a clinician's patients and also across a medical provider network (MPN) for querying quality control, consistency and completeness of reports. This also enables an opportunity for correctional interventions within a network and an improvement in the quality of the report produced for stakeholders. The data can also be analyzed for statistical variance within an individual report, a clinician's account and across the MPN. Additionally, after a risk score for an impairment rating is output, the risk score can be uploaded to a historical evaluation database for a percentile creation against other reports of similar body systems. This can further enable a determination of best practices and behaviors such that a more complete and accurate impairment rating is obtained in an educational and constructive manner. As such, the method and system for calculating a deficiency analysis that provides a percentage of missing data for an impairment rating based on an observed data set such as described herein has many advantages.
