Abstract:
A method, system, and computer program product determines a controlled substance use indicator to enable a physician, or other prescriber, to quickly review a numerical score that reflects a patient&#39;s past drug use and is indicative of proper, or improper, future drug use. This score analyzes many aspects of a patient&#39;s past activities to determine multiple individual indicator values that may be selectively weighted to create a final controlled substance use indicator. Such individual indicator values may include: a usage related indicator factoring in the patient&#39;s past drug use, particularly the type of controlled substances used; an instruction related indicator that may consider the patient&#39;s past use of prescribers, quantity of prescriptions, or the number of open prescriptions from different prescribers; a dispensing related indicator that examines a patient&#39;s use of pharmacies in filling prescriptions; or even an auxiliary indicator that may reflect the patient&#39;s number of active prescriptions.

     TECHNICAL FIELD 
       [0002]    The present invention relates to predicting proper narcotic usage; particularly, to a method and system for creating numerous controlled substance use indicators to predict the likelihood of a patient correctly using a prescription drug of interest. 
       BACKGROUND 
       [0003]    Prescription drug abuse is one of the leading forms of drug abuse in the US. The types of drugs most commonly abused today are narcotics, sedatives, and stimulants. There are other categories of drugs that can be abused besides these three types, one such example being anabolic steroids, and collectively these drugs are classified as controlled substances by the DEA. Narcotics have risen to the top of all controlled substances in terms of the number of people who abuse them. Approximately 3% of 12 year old children in the US admit to using Vicodin in the previous year, while about 15% of 18-25 year old men and women admit to the same. It is estimated that approximately 15 million people in the US abuse prescription drugs. Emergency Departments have seen a 111% increase in the number of visits from people who are seeking narcotics for their addiction. Prescription drug abuse is the number one drug abuse problem in the US. 
         [0004]    Healthcare entities have to deal with this problem every day (pharmacists, hospitals, providers), as do law enforcement officials and educators. One of the tools physicians, physician assistants, pharmacists, and law enforcement can use is a state based Prescription Monitoring Program, or PMP. One such example is available at ohioPMP.org. All 50 states now have, or are developing, these programs and they are usually funded at the Federal level. These programs require that pharmacists and providers who dispense medications directly report every narcotic distribution to the state PMP. The state PMP maintains a database of these “transactions.” Approved providers can log into the state PMP website and retrieve a patient&#39;s narcotic use information in PDF format. This document may be 1-10 pages long and annotates very specific details about prescription usage (who, where, when, what, how much, when written, when filled, new or refill, etc.). Presumably, a provider, such as a physician, physician&#39;s assistant, or pharmacist would utilize this site whenever they were concerned about the potential for prescription drug abuse. However, providers use this service at a relatively low rate because it is a somewhat arduous process to navigate to the site, login, enter demographic data, wait for the report search, download the PDF and then read all of the data. Ohio reports that only 17% of prescribers in the state have even applied for access to the PMP and fewer than that use the system regularly. 
       SUMMARY 
       [0005]    In an embodiment, a computer-implemented method for determining the likelihood of proper prescription drug use by a patient comprises obtaining a record from a prescription database, the record indicative of a plurality of prescriptions corresponding to the patient, and generating, with one or more computer processors, a usage related indicator by comparing at least one of a prescription drug type corresponding to two or more of the plurality of prescriptions or a prescription drug quantity corresponding to the two or more of the plurality of prescriptions with a plurality of general population prescription drug use data. The method further comprises generating, with the one or more computer processors, an instruction related indicator by comparing a prescriber corresponding to at least one of the plurality of prescriptions to a plurality of general population prescription drug instruction data, and combining, with the one or more computer processors, the usage related indicator and the instruction related indicator to produce a prescription drug use indicator for display on a visual medium. 
         [0006]    In another embodiment, a computer-implemented method for determining the likelihood of proper prescription drug use by a patient comprises obtaining a record from a prescription database on a server, the record indicative of a plurality of prescriptions corresponding to the patient, a morphine equivalents unit percentile for a give morphine equivalents unit period by comparing at least one of a narcotic type of two or more of the plurality of prescriptions or a narcotic quantity of two or more of the plurality of prescriptions with a plurality of general population prescription drug use data. The method further comprises generating, with the one or more computer processors, an instruction related indicator including: a) identifying a potential prescription overlap situation of at least two prescribers during a prescription overlap period to produce a prescription overlap percentile; and b) creating of a prescriber indicator by comparing a prescriber quantity with the plurality of general population prescription drug use data to determine a prescriber percentile for a given prescriber period. Still further the method comprises combining, with the one or more computer processors, the prescription overlap percentile, the prescriber percentile, and the morphine equivalents unit percentile to produce a narcotics use indicator for display on a visual medium.

       DETAILED DESCRIPTION 
       [0020]    The claimed method, system, and computer program product for determining a controlled substance use indicator enables a significant advance in the state of the art. Of note, when the controlled substances of interest are narcotics, the result is a narcotics use indicator. Likewise, when sedatives or stimulants are the focus they result in a sedative use indicator and a stimulant use indicator. 
         [0021]    As previously touched upon, a prescription database ( 6000 ) may reside on a state PMP server, however one skilled in the art will appreciate that the prescription database ( 6000 ) described herein is not limited to a statewide system or a federal system, as it may be a hospital specific prescription database, a commercial prescription database, or community specific prescription database ( 6000 ). Similarly, the prescription database ( 6000 ) need not reside on a server but rather may reside on a local memory device in a standalone manner, and further, in anticipation of advances in health care IT infrastructure, the prescription database ( 6000 ) may be created for an individual patient broadly electronically querying a network of health care providers and aggregating the collected data, which may be completed in virtually real-time. Regardless of the scope, location, or creation of the prescription database ( 6000 ), it contains at least one of record ( 6100 ) indicative of the prescription drug use by the patient. One illustrative record ( 6100 ) is seen in  FIG. 4 . A record ( 6100 ) may contain information such as a patient ID ( 6105 ), a prescription written date ( 6110 ), a prescription expiration date ( 6115 ), a prescription period ( 6120 ), a prescriber ( 6145 ), a prescriber location ( 6150 ), a distributor ( 6155 ), a distributor location ( 6160 ), and a distribution date ( 6165 ). The record ( 6100 ) may even contain data indicative of the number of times it has been accessed, such as a record request date ( 6200 ), data indicative of who has accessed the record such as a record requester ( 6300 ) data field, as well as where the requester is located, such as a requester location ( 6310 ) data field. 
         [0022]    The record ( 6100 ) may also contain data pertaining to the prescriptions that have been filled for a particular patient, whether they are for narcotics or other controlled substances. Therefore, the record ( 6100 ) may contain data about a prescribed narcotic such as a narcotic type ( 6125 N), a narcotic strength ( 6130 N), a narcotic form ( 6135 N), and a narcotic quantity ( 6140 N). The record ( 6100 ) may contain similar information regarding other prescribed controlled substances such as a controlled substance type ( 6125 C), a controlled substance strength ( 6130 C), a controlled substance form ( 6135 C), and a controlled substance quantity ( 6140 C). Some controlled substance types potentiate each other and become more dangerous when taken together. Two such examples are narcotics and benzodiazepines. For example, the act of consuming a narcotic like demerol can become more dangerous by combining it with a benzodiazepine such as Lorazepam. Thus, in these examples the element numbers for narcotics end with the letter “N” and those for other related controlled substances end in the letter “C”, while sharing the same numerical references. These are simply examples of the data that may be contained within a record ( 6100 ) and are not all required, nor are these the only types of data that may reside in a record ( 6100 ). 
         [0023]    The present method, system, and computer program product retrieve patient specific data from a record ( 6100 ) and transforms the data into at least one indicator by comparing the patient specific data with a plurality of general population prescription drug use data. The indicator, or indicators, are then transformed into a controlled substance use indicator ( 10 ) via the application of at least one adjustment factor. A diagram of one embodiment of the procedure is seen in  FIG. 5  wherein at least one piece of patient specific data is retrieved from a record ( 6100 ) and is then transformed into at least one of a usage related indicator ( 1000 ), an instruction related indicator ( 2000 ), a dispensing related indicator ( 3000 ), or an auxiliary indicator ( 4000 ) by comparing the patient specific data with a plurality of general population prescription drug use data. Then at least one adjustment factor ( 5000 ) is applied to at least one of the indicators to create the narcotics use indicator ( 10 ). 
         [0024]    In one embodiment patient specific data including at least a prescriber ( 6145 ), a distributor ( 6155 ), a narcotic type ( 6125 N), a narcotic strength ( 6130 N), and a narcotic quantity ( 6140 N) is retrieved from the record ( 6100 ). Next, at least one prescription drug use processor receives this data and transforms it into at least two indicators; namely, a usage related indicator ( 1000 ) and an instruction related indicator ( 2000 ). The usage related indicator ( 1000 ) is created by comparing at least the patient information concerning the narcotic type ( 6125 N), the narcotic strength ( 6130 N), and the narcotic quantity ( 6140 N) with a plurality of general population prescription drug use data; while the instruction related indicator ( 2000 ) is created by comparing at least the patient information concerning the prescriber ( 6145 ) with the plurality of general population prescription drug use data. 
         [0025]    The act of comparing patient specific data with the plurality of general population prescription drug use data can mean a number of things, as will be explained in greater detail later. In the big picture the comparison simply results in at least an indication of where the patient data ranks when compared to similar data that is representative of a larger population of patients. For example, one embodiment may simply identify whether the patient data is in a below normal range, a normal range, or an above normal range when compared to a larger population of patients. Alternatively, another embodiment may determine a percentile ranking of the patient data compared to the larger population of patients. 
         [0026]    Finally, at least one prescription drug use processor applies an adjustment factor ( 5000 ) to at least one of the usage related indicator ( 1000 ) and the instruction related indicator ( 2000 ) to create an adjusted indicator, and transforms the adjusted indicator into a controlled substance use indicator ( 10 ) to display on a visual media. The controlled substance use indicator ( 10 ) is created within 5-10 seconds of the request. 
         [0027]    The embodiment above utilized only a usage related indicator ( 1000 ) and an instruction related indicator ( 2000 ). However, an example will be explained with respect to  FIGS. 10 and 11  and includes a discussion of all the illustrated data and indicators for simplicity&#39;s sake only and the presence of such in this explanation is not an indication that all the data and indicators discussed are necessary. The lower table in  FIG. 10  represents patient specific data that has been acquired from a record ( 6100 ) in a prescription database ( 6000 ), however it should be noted that for the previous embodiment it is not necessary that all of this patient data is retrieved from the record ( 6100 ). This particular patient had four prescriptions written between Feb. 18, 2010 and May 23, 2010 and filled between Feb. 22, 2010 and May 27, 2010; two are for the narcotic demerol and two are for the controlled substance lorazepam, which is why the demerol entry is labeled as  6125 N while the lorazepam entry is labeled as  6125 C (N for narcotic, C for controlled substance). 
         [0028]    The upper table in  FIG. 10  represents numerous indicators created from the patient data, as well as numerous adjustment factors ( 5000 ) used to arrive at the ultimate narcotics use indicator ( 10 ) appearing in the upper left corner of the figure as a NARx score. In one embodiment the usage related indicator ( 1000 ) may be a morphine equivalents unit indicator ( 1100 ). In this embodiment the narcotic type ( 6125 N), the narcotic strength ( 6130 N), and the narcotic quantity ( 6140 N) are transformed into a morphine equivalents unit quantity ( 1120 ), seen in the far right column of the lower table. The morphine equivalents unit quantity ( 1120 ) is then compared with the plurality of general population prescription drug use data to determine a morphine equivalents unit percentile ( 1140 ) for a given morphine equivalents unit period ( 1110 ). Thus, in the upper table of  FIG. 10 , within the “Period A” column, which corresponds to the morphine equivalents unit period ( 1110 ), the row labeled “Morphine” contains the morphine equivalents unit quantity ( 1120 ), abbreviated MEU Qty in the table, on the left side of the hash mark, and the morphine equivalents unit percentile ( 1140 ), abbreviated MEU % in the table, on the right side of the hash mark. 
         [0029]    The upper table in  FIG. 11  contains the actual values corresponding to the lower table, illustrating that in the past 60 days, the morphine equivalents unit period ( 1110 ), from the reference date of Jul. 1, 2010, the morphine equivalents unit quantity ( 1120 ) prescribed is 450; although it should be noted that the morphine equivalents unit quantity ( 1120 ) is not limited to the amount prescribed during the period but rather could be the amount consumed during the period. In this specific example, the morphine equivalents unit quantity ( 1120 ) places this patient in the fifty-first percentile, which is the morphine equivalents unit percentile ( 1140 ) displayed on the right side of the hash mark in the upper table of  FIG. 11 . 
         [0030]    With reference again to  FIG. 10 , the instruction related indicator ( 2000 ) may include the step of identifying a potential prescription overlap situation when the record ( 6100 ) includes at least two prescribers ( 6145 ) during a prescription overlap period ( 2310 ). A prescription overlap indicator ( 2300 ) may then be created by determining a prescription overlap quantity ( 2320 ) that is the total number of days that the prescription period ( 6120 ) of the each prescriber ( 6145 ) coincide. Further, comparison of the prescription overlap quantity ( 2320 ) with the plurality of general population prescription drug use data yields a prescription overlap percentile ( 2340 ). For example, when the prescription overlap period ( 2310 ) is 60 days from the reference date of Jul. 1, 2010, as in  FIG. 11 , there were three prescriptions open within that period, only two of which are for narcotics. Therefore, within the prescription overlap period ( 2310 ) of 60 days, there were 8 days, namely May 1st through May 8th, in which the two narcotic prescriptions for demerol overlapped. Therefore, the prescription overlap quantity ( 2320 ) is 8, as seen in the upper table of  FIG. 11 , which puts this patient in the eighteenth percentile, which is the prescription overlap percentile ( 2340 ). A high prescription overlap quantity ( 2320 ), or prescription overlap percentile ( 2340 ), is indicative of likely improper prescription drug use, particularly in cases where the prescription overlap quantity ( 2320 ) includes days in which a patient had multiple open prescriptions for the same narcotic originating from different prescribers. The prescription overlap indicator ( 2300 ) may be applied only to narcotic prescriptions, only to controlled substance prescriptions, or to both. 
         [0031]    Another possible usage related indicator ( 1000 ) is an associated controlled substance unit indicator ( 1300 ). The associated controlled substance unit indicator ( 1300 ) is created in part by comparing the associated controlled substance quantity ( 6140 C) with the plurality of general population prescription drug use data to determine a controlled substance unit percentile ( 1340 ) for a given controlled substance unit period ( 1310 ). Thus, in the upper table of  FIG. 10 , within the “Period A” column, which corresponds to the controlled substance unit period ( 1310 ), the row labeled “Controlled” contains the associated controlled substance unit quantity ( 1320 ), abbreviated CTRL Sub Qty in the table, on the left side of the hash mark, and the controlled substance unit percentile ( 1340 ), abbreviated CTRL Sub % in the table, on the right side of the hash mark. 
         [0032]    The upper table in  FIG. 11  contains the actual values corresponding to the lower table, illustrating that in the past 60 days, the associated controlled substance unit period ( 1310 ), from the reference date of Jul. 1, 2010, the controlled substance unit quantity ( 1320 ) prescribed is 90; although it should be noted that the controlled substance unit quantity ( 1320 ) is not limited to the amount prescribed during the period but rather could be the amount consumed during the period. In this specific example, the controlled substance unit quantity ( 1320 ) places this patient in the ninety-fifth percentile, which is the controlled substance unit percentile ( 1340 ) displayed on the right side of the hash mark in the upper table of  FIG. 11 . 
         [0033]    Another possible instruction related indicator ( 2000 ) is a prescriber indicator ( 2200 ). The creation of a prescriber indicator ( 2200 ) is created in part by comparing a prescriber quantity ( 2220 ) with the plurality of general population prescription drug use data to determine a prescriber percentile ( 2240 ) for a given prescriber period ( 2210 ). Thus, in the upper table of  FIG. 10 , within the “Period A” column, which corresponds to the prescriber period ( 2210 ), the row labeled “Prescribers” contains the prescriber unit quantity ( 2220 ), abbreviated Prescriber Qty in the table, on the left side of the hash mark, and the prescriber percentile ( 2240 ), abbreviated Prescriber % in the table, on the right side of the hash mark. 
         [0034]    The upper table in  FIG. 11  contains the actual values corresponding to the lower table, illustrating that in the past 60 days, the prescriber period ( 2210 ), from the reference date of Jul. 1, 2010, the prescriber quantity ( 2220 ) is 2. In this specific example, the prescriber quantity ( 2220 ) places this patient in the thirty-three percentile, which is the prescriber percentile ( 2240 ) displayed on the right side of the hash mark in the upper table of  FIG. 11 . 
         [0035]    In addition to the usage related indicator ( 1000 ) and the instruction related indicator ( 2000 ), the method may incorporate a dispensing related indicator ( 3000 ). The dispensing related indicator ( 3000 ) is created by comparing at least the patient information concerning the distributor ( 6155 ) with the plurality of general population prescription drug use data, and in this embodiment the adjustment factor ( 5000 ) is then applied to at least one of the usage related indicator ( 1000 ), the instruction related indicator ( 2000 ), and the dispensing related indicator ( 3000 ). 
         [0036]    In one particular embodiment the dispensing related indicator ( 3000 ) is a distribution source indicator ( 3100 ). The creation of a distribution source indicator ( 3100 ) is created in part by comparing a distribution source quantity ( 3120 ) with the plurality of general population prescription drug use data to determine a distribution source percentile ( 3140 ) for a given distribution source period ( 3110 ). Thus, in the upper table of  FIG. 10 , within the “Period A” column, which corresponds to the distribution source period ( 3110 ), the row labeled “Pharmacies” contains the distribution source quantity ( 3120 ), abbreviated Dist Source Qty in the table, on the left side of the hash mark, and the distribution source ( 3140 ), abbreviated Dist Source % in the table, on the right side of the hash mark. 
         [0037]    The upper table in  FIG. 11  contains the actual values corresponding to the lower table, illustrating that in the past 60 days, the distribution source period ( 3310 ), from the reference date of Jul. 1, 2010, the distribution source quantity ( 3120 ) is 1. In this specific example, the distribution source quantity ( 3120 ) places this patient in the twentieth percentile, which is the distribution source percentile ( 3140 ) displayed on the right side of the hash mark in the upper table of  FIG. 11 . 
         [0038]    Now that the first data column associated with the five rows of data in the upper tables of  FIGS. 10 and 11  have been discussed, several additional steps will be explained; however, additional indicators will be discussed later. It should be noted again that all five indicators ( 2220 ,  3120 ,  1120 ,  1320 ,  2320 ) of these two figures are not required, rather this is merely one illustrative embodiment being explained in detail. In these figures three types of indicators have been examined, namely two usage related indicators ( 1000 ) including a morphine equivalents unit indicator ( 1100 ) and an associated controlled substance unit indicator ( 1300 ), two instruction related indicators ( 2000 ) including a prescriber indicator ( 2200 ) and a prescription overlap indicator ( 2300 ), and one dispensing related indicator ( 3000 ) that was a distribution source indicator ( 3100 ). As previously mentioned, an adjustment factor ( 5000 ) may be applied to any, or all, of these indicators to weight their relevance in predicting proper prescription drug use and ultimately arrive at a narcotics use indicator ( 10 ). 
         [0039]    With specific reference to the embodiment of  FIGS. 10 and 11  again, the adjustment factor ( 5000 ) is seen in the right column of the upper tables. In this embodiment each of the usage related indicators ( 1000 ) have a usage adjustment factor ( 5100 ), each of the instruction related indicators ( 2000 ) have an instruction adjustment factor ( 5200 ), and the dispensing related indicator ( 3000 ) has a dispensing adjustment factor ( 5300 ). Even further, as seen in the right column of the upper table of  FIG. 11 , in this one embodiment, the morphine equivalents unit indicator ( 1100 ) has a narcotic usage adjustment factor ( 5110 ), the controlled substance unit indicator ( 1300 ) has a controlled substance usage adjustment factor ( 5120 ), the prescriber indicator ( 2200 ) has a prescriber adjustment factor ( 5210 ), the prescription overlap indicator ( 2300 ) has an overlap adjustment factor ( 5220 ), and the distribution source indicator ( 3100 ) has a dispensing adjustment factor ( 5300 ). Here the narcotic usage adjustment factor ( 5110 ) is four times greater than the other adjustment factors because the morphine equivalents unit percentile ( 1140 ) is more directly indicative of overall prescription drug use. 
         [0040]    Referring now to  FIG. 11  and focusing only on the “60 Day” column and the “Wt.” column, a narcotics use indicator ( 10 ) can be developed for this single period. For example, the narcotics use indicator ( 10 ) may be simply a weighted average of the five percentile values ( 2240 ,  3140 ,  1140 ,  1340 ,  2340 ). In this case, taking the sum of the prescriber percentile ( 2240 ) multiplied by the prescriber adjustment factor ( 5210 ), plus the distribution source percentile ( 3140 ) multiplied by the dispensing adjustment factor ( 5300 ), plus the morphine equivalents unit percentile ( 1140 ) multiplied by the narcotic usage adjustment factor ( 5110 ), plus the controlled substance unit percentile ( 1340 ) multiplied by the controlled substance usage adjustment factor ( 5120 ), plus the prescription overlap percentile ( 2340 ) multiplied by the overlap adjustment factor ( 5220 ); and dividing that sum by the sum of all the adjustment factors ( 5210 ,  5300 ,  5110 ,  5120 ,  5220 ) produces a number that is effectively a weighted percentile. In this example, the result would be [(33*1)+(20*1)+(51*4)+(95*1)+(18*1)]/(1+1+4+1+1)=46.25. For the convenience of a treating prescriber that requested the narcotics use indicator ( 10 ) this number may then be rounded to the nearest whole number which in this case is 46. In a further embodiment, it is likely that the treating prescriber would also like to immediately know the number of currently active prescriptions, yet still have a single convenient reference number, or score, to represent the likelihood of prescription drug abuse. Therefore, in this further embodiment, the number of active prescriptions is an active prescription indicator ( 4300 ) and is added as a third digit in the narcotics use indicator ( 10 ). In the example of  FIG. 11 , there are no active prescriptions, so the active prescription indicator ( 4300 ) is 0, which is applied to the end of the weighted percentile previously calculated to be 46 to arrive at a three digit narcotics use indicator ( 10 ) of 460. A treating prescriber can easily look at this narcotics use indicator ( 10 ) and quickly assess the likelihood that this particular patient is going to correctly utilize a prescription for a narcotic medication and/or a controlled substance. In this embodiment a patient with 9 or more active prescriptions would receive a three digit narcotics use indicator ( 10 ) of 469, which would immediately draw the attention of the prescriber, possibly warranting a more detailed review of the patient&#39;s prescription drug use. Thus, past patient prescription drug use data is transformed into a numerical narcotics use indicator ( 10 ) displayed on a visual media. The visual media may be a Cathode Ray Tube (CRT) monitor, a Liquid Crystal Display (LCD) monitor, a plasma monitor, a projector and screen, paper, and/or any other such visual display device known to those of ordinary skill in the art. 
         [0041]    While the example above focused on a single period of time,  FIG. 11  illustrates that the values just determined above may be determined for multiple periods. The upper table of  FIG. 11  illustrates one embodiment in which 4 such periods are utilized. In such an embodiment, multi period percentiles may be determined for each indicator. Specifically, the “AVG” column of the table illustrates a multi period prescriber percentile ( 2250 ), a multi period distribution source percentile ( 3150 ), a multi period morphine equivalents unit percentile ( 1150 ), a multi period controlled substance percentile ( 1350 ), and a multi period prescriber overlap percentile ( 2350 ). In this embodiment, each of these multi period percentiles are simply the average percentile value for the given number of periods. Thus, the multi period prescriber percentile ( 2250 ) is simply the sum of the four individual period specific prescriber percentiles ( 2240 ) divided by the number of periods, in this case four, leading to (33+38+28+20)/4=29.75; and likewise for the other four indicators. Thus, the adjustment factors ( 5000 ) may be applied to these multi period percentiles in exactly the same manner as previously discussed to arrive at a weighted percentile. In this example, the result would be [(29.75*1)+(26.75*1)+(70.25*4)+(64*1)+(16.25*1)]/(1+1+4+1+1)=52.29. For the convenience of a treating prescriber that requested the narcotics use indicator ( 10 ) this number may then be rounded to the nearest whole number which in this case is 52. Then in the embodiment incorporating the active prescription indicator ( 4300 ), which remains at 0, the three digit narcotics use indicator ( 10 ) would be 520, as seen in  FIG. 11 . Therefore, in this particular example, looking at a two year time span rather than just a two month period raises the three digit narcotics use indicator ( 10 ) from 460 to 520. Obviously the lower table of  FIG. 11  has been abbreviated and does not contain all of the prescriptions required to calculate the data for the 180 day period, the 365 day period, and the 730 day period, but the procedure is the same as just reviewed for the 60 day period. 
         [0042]    A benefit of incorporating multiple periods is that because all the periods may have the same start date, i.e. the reference date in  FIGS. 10 and 11 , the data contained in the first period is also included in a second period, and likewise the data in the third period includes that in the first and the second period, and likewise the data in the fourth period includes that in the first period, second period, and third period. Therefore, in one embodiment of  FIG. 11 , namely when all four periods are considered, the morphine equivalents unit quantity ( 1120 ) of 450 when the morphine equivalents unit period ( 1110 ) is 60 days, is also included in the morphine equivalents unit quantity ( 1120 ) when the morphine equivalents unit period ( 1110 ) is 180 days, 365 days, and 730 days. Therefore, in this embodiment the multi period morphine equivalents unit percentile ( 1150 ) is the average of the four periods wherein each period includes the morphine equivalents unit quantity ( 1120 ) from the first period; thus, the most recent data values are preferentially weighted. Although this preferential weighting is described above with respect to the multi period morphine equivalents unit percentile ( 1150 ), it may be applied to the determination of a multi period narcotic unit percentile ( 1250 ), a multi period controlled substance unit percentile ( 1350 ), a multi period prescription percentile ( 2150 ), a multi period prescriber percentile ( 2250 ), a multi period prescription overlap percentile ( 2350 ), a multi period distribution source percentile ( 3150 ), or a multi period distribution geography percentile ( 3250 ). 
         [0043]    In another embodiment any of the adjustment factors may be automatically adjusted if preset criteria are met concerning data that highly correlates with improper prescription drug use. For example, as previously discussed with respect to  FIG. 11 , patients that have a prescription overlap quantity ( 2320 ) including days in which a patient had multiple open prescriptions for the same narcotic originating from different prescribers may flag an automatic adjustment to the overlap adjustment factor ( 5220 ) of at least twice the normal overlap adjustment factor ( 5220 ). Likewise, in another embodiment the prescriber adjustment factor ( 5210 ) may be automatically adjusted by a factor of at least two if a patient holds onto prescriptions from the same prescriber and then has them filled so that at least two controlled substance prescriptions are open at the same time based upon prescriptions for the same controlled substance by a single prescriber. 
         [0044]    As seen in  FIG. 7 , yet another possible instruction related indicator ( 2000 ) is a prescription indicator ( 2100 ). The creation of a prescription indicator ( 2100 ) is created in part by comparing a prescription quantity ( 2120 ) with the plurality of general population prescription drug use data to determine a prescription percentile ( 2140 ) for a given prescription period ( 2110 ). Thus, one with skill in the art will recognize that this prescription indicator ( 2100 ) is yet another indicator that may be found in the upper tables of  FIGS. 10 and 11  and weighted in the same manner previously discussed with respect to the other indicators to influence the narcotics use indicator ( 10 ). As such, the “Period A” column, would correspond to the prescription period ( 2110 ), and a row labeled “Prescriptions” would contain the prescription unit quantity ( 2120 ) on the left side of a hash mark, and the prescription percentile ( 2140 ) on the right side of the hash mark. Similarly, the instruction adjustment factor ( 5200 ) may include a prescription adjustment factor to weight the significance of the prescription indicator ( 2100 ) in the narcotics use indicator ( 10 ). 
         [0045]    Further, as seen in  FIG. 6 , another possible usage related indicator ( 1000 ) is a narcotic unit indicator ( 1200 ). The narcotic unit indicator ( 1200 ) is created in part by comparing the narcotic quantity ( 6140 N) with the plurality of general population prescription drug use data to determine a narcotic unit percentile ( 1240 ) for a given narcotic unit period ( 1210 ). Thus, one with skill in the art will recognize that this narcotic unit indicator ( 1200 ) is yet another indicator that may be found in the upper tables of  FIGS. 10 and 11  and weighted in the same manner previously discussed with respect to the other indicators to influence the narcotics use indicator ( 10 ). As such, the “Period A” column, would correspond to the prescription period ( 2110 ), and a row labeled “Narcotics” would contain the narcotic unit quantity ( 1220 ) on the left side of a hash mark, and the narcotic unit percentile ( 1240 ) on the right side of the hash mark. Similarly, the usage adjustment factor ( 5100 ) may include a narcotic unit adjustment factor to weight the significance of the narcotic unit indicator ( 1200 ) in the narcotics use indicator ( 10 ). 
         [0046]    As seen in  FIG. 8 , another embodiment includes a dispensing related indicator ( 3000 ) that is a distribution geography indicator ( 3200 ). The creation of a distribution geography indicator ( 3200 ) is created in part by comparing a distribution geography distance ( 3220 ) with the plurality of general population prescription drug use data to determine a distribution geography percentile ( 3240 ) for a given distribution geography period ( 3210 ). Thus, one with skill in the art will recognize that this distribution geography indicator ( 3200 ) is yet another indicator that may be found in the upper tables of  FIGS. 10 and 11  and weighted in the same manner previously discussed with respect to the other indicators to influence the narcotics use indicator ( 10 ). As such, the “Period A” column, would correspond to the distribution geography period ( 3210 ), and a row labeled “Geography” would contain the distribution geography distance ( 3220 ) on the left side of a hash mark, and the distribution geography percentile ( 3240 ) on the right side of the hash mark. Similarly, the dispensing adjustment factor ( 5300 ) may include a distribution geography adjustment factor to weight the significance of the distribution geography indicator ( 3200 ) in the narcotics use indicator ( 10 ). In one embodiment the distribution geography distance ( 3220 ) is the total distance between the patient&#39;s home address and the location of the pharmacy, or pharmacies, that fills prescriptions during the distribution geography period ( 3210 ). In another embodiment the distribution geography distance ( 3220 ) is the distance between the locations of the pharmacies that fill prescriptions during the distribution geography period ( 3210 ). In yet another embodiment the distribution geography distance ( 3220 ) is the distance between the locations of only pharmacies that fill prescriptions for drugs within the same family during the distribution geography period ( 3210 ). 
         [0047]    As seen in  FIGS. 5 and 9 , another embodiment includes an auxiliary indicator ( 4000 ) that is a controlled substance request indicator ( 4100 ), The controlled substance request indicator ( 4100 ) is created in part by comparing the number of times, a controlled substance request quantity ( 4120 ), that a patient has had a narcotics use indicator ( 10 ) requested by a prescriber during a given period, namely a controlled substance request period ( 4110 ). The controlled substance request quantity ( 4120 ) may then be compared with the plurality of general population prescription drug use data to determine a controlled substance request percentile ( 4240 ) for the given controlled substance request period ( 4110 ). Thus, one with skill in the art will recognize that this controlled substance request indicator ( 4100 ) is yet another indicator that may be found in the upper tables of  FIGS. 10 and 11  and weighted in the same manner previously discussed with respect to the other indicators to influence the narcotics use indicator ( 10 ). As such, the “Period A” column, would correspond to the controlled substance request period ( 4110 ), and a row labeled “controlled substance requests” would contain the controlled substance request quantity ( 4120 ) on the left side of a hash mark, and the NAR request percentile ( 4140 ) on the right side of the hash mark. Similarly, an auxiliary indicator adjustment factor ( 5400 ) may include a controlled substance request adjustment factor to weight the significance of the controlled substance request indicator ( 4100 ) in the narcotics use indicator ( 10 ). In another embodiment, this controlled substance request adjustment factor may be automatically increased if the amount of narcotics use indicator ( 10 ) requests has exceeded a preset normal number of requests. 
         [0048]    Even further, another embodiment includes an auxiliary indicator ( 4000 ) that is a controlled substance rate of change indicator ( 4200 ). The controlled substance rate of change indicator ( 4200 ) is created in part by comparing how the patient&#39;s narcotics use indicator ( 10 ) has changed over a period, or periods, of time to the rate of change associated with the plurality of general population prescription drug use data. For example, a request for a narcotics use indicator ( 10 ) may result in the determination of a first narcotics use indicator at a fixed time interval prior to the request date, and then the determination of a second narcotics risk indicator at a rate of change period ( 4210 ) prior to the fixed time interval. The difference between the first and second narcotics risk indicators, referred to as a controlled substance variation ( 4220 ), may then be used to adjust the presently requested narcotics use indicator if a threshold controlled substance variation ( 4220 ) is exceeded. The controlled substance variation ( 4220 ) may be compared with the plurality of general population prescription drug use data to determine a rate of change percentile ( 4240 ) for the given rate of change period ( 4210 ). Thus, one with skill in the art will recognize that this controlled substance rate of change indicator ( 4200 ) is yet another indicator that may be found in the upper tables of  FIGS. 10 and 11  and weighted in the same manner previously discussed with respect to the other indicators to influence the presently requested narcotics use indicator ( 10 ). As such, the “Period A” column, would correspond to the rate of change period ( 4210 ), and a row labeled “Rate of Change” would contain the controlled substance variation ( 4220 ) on the left side of a hash mark, and the rate of change percentile ( 4240 ) on the right side of the hash mark. Similarly, the auxiliary indicator adjustment factor ( 5400 ) may include a rate of change adjustment factor to weight the significance of the controlled substance rate of change request indicator ( 4200 ) in the narcotics use indicator ( 10 ). In another embodiment, this controlled substance rate of change adjustment factor may be automatically increased if the controlled substance variation ( 4220 ) has exceeded a preset normal number of requests. 
         [0049]    Throughout this document there are multiple references to a step of comparing a quantity, whether it is the 1120, 1220, 1320, 2120, 2220, 2320, 3120, 3220, 4120, or 4220 quantity, “with the plurality of general population prescription drug use data” to determine an indicator, whether it be a usage related indicator ( 1000 ), an instruction related indicator ( 2000 ), or a dispensing related indicator ( 3000 ). In some of the many disclosed embodiments the determination of an indicator includes a determination of whether the quantity is within an acceptable range or an unacceptable range, however other embodiments determine approximate percentile rankings of the quantity compared to the general population data, such as the 1140, 1240, 1340, 2140, 2240, 2340, 3140, 3240, 4140, or 4240 percentiles. 
         [0050]    The general population prescription drug use data referenced is data associated with at least 1000 patients over the period of interest. In one embodiment this general population data is present in the database ( 6000 ) and is extracted for use in arriving at the indicators, or in some embodiments the percentile(s). The general population data need not be extracted each time patient specific data is retrieved from the database ( 6000 ); rather the general population data may be extracted after extended intervals, which may be months or even years. The general population prescription drug use data may be from a statewide or federal prescription database, a hospital specific prescription database, a commercial prescription database, or community specific prescription database. Thus, in yet another embodiment the general population prescription drug use data referenced is data associated with at least 1,000,000 patients over the period of interest; while yet a further embodiment, such as data used in generating  FIGS. 10 and 11 , utilizes data associated with at least 5,000,000 patients over the period of interest. 
         [0051]    Therefore, the act of comparing a quantity “with the plurality of general population prescription drug use data” to determine an indicator may include the step of previously acquiring the general population prescription drug use data, processing the data, converting the data into a quickly accessible electronic format, and storing the converted data on hardware for use in determining the final narcotics risk indicator ( 10 ) in less than 5 seconds, whether the general population prescription drug data is local or on a hardware device on the other side of the planet. Thus, in one embodiment a local prescription drug use processor securely retrieves and stores into memory patient specific data from a remote database ( 6000 ), the local prescription drug use processor securely retrieves and stores into memory previously compiled and transformed data representative of the general populations prescription drug use, the local prescription drug use processor retrieves portions of this stored data to form and store at least a usage related indicator ( 1000 ) and an instruction related indicator ( 2000 ), the local prescription drug use processor applies an adjustment factor ( 5000 ) to at least one of usage and instruction related indicators ( 1000 ,  2000 ) and transforms them into a numerical narcotics use indicator ( 10 ), and the local prescription drug use processor formats and transmits the narcotics use indicator ( 10 ) to display on a visual media. Further, in light of confidential patient data security, the local prescription drug use processor may then clear the patient specific data from the local memory, as well as leave a timestamp within the remote database ( 6000 ) to serve as an indicator of when a patient&#39;s data was accessed. The prescription drug use processor may further securely transmit the narcotics use indicator ( 10 ) back to the database ( 6000 ) for storage and retrieval during subsequent data requests in determining updated narcotics use indicators ( 10 ). Thus, a system for carrying out the determination of a narcotics use indicator ( 10 ) may consist of several securely connected pieces of hardware communicating with the specially programmed prescription drug use processor to determine the narcotics use indicator ( 10 ). As the local prescription drug use processor retrieves the patient specific data from the database ( 6000 ), it may create a local patient-specific database for temporarily storing and processing data. The local patient-specific database is cleared of patient specific data upon the creation of the narcotics use indicator ( 10 ) and any associated reports that are simultaneously created. 
         [0052]    The analysis of large quantities of data is well known in the field of statistics to identify acceptable ranges, unacceptable ranges, and percentile rankings, and therefore will not be reviewed in detail. However, one of many embodiments will be discussed for illustrative purposes. For instance,  FIG. 1  illustrates raw data concerning the number of people in the general population drug use data on the y-axis, and the number of prescribers for a given period across the x-axis. It is clear from this figure that during this particular period, the overwhelming majority of patients only fill prescriptions from a single prescriber. A further embodiment determines a log normal distribution of the data, as seen in  FIG. 2 , which has the effect of straightening out the curve and spreading out the values. In this example, a log normal distribution may be preferred because using the raw data only would put a very small quantity of prescribers at the 99th percentile. This would mean that above this very small quantity of prescribers there would be no differentiation among patients. In yet another embodiment the raw data, or the log natural data, may be used to create a curve from which a percentile value is easily determined, as seen in  FIG. 3 . For example, the area under the curve seen in  FIG. 3  and to the left of the line labeled “A” puts this number of prescribers in the 15th percentile, whereas the position of the line labeled “B” puts this number of prescribers in the 90th percentile.  FIGS. 6-9  schematically illustrate similar analysis of data to produce one or more of the following curves, and one or more of the following percentiles; namely, morphine equivalents unit curve ( 1130 ), morphine equivalents unit percentile ( 1140 ), narcotic unit curve ( 1230 ), narcotic unit percentile ( 1240 ), controlled substance unit curve ( 1330 ), controlled substance unit percentile ( 1340 ), prescription curve ( 2130 ), prescription percentile ( 2140 ), prescriber curve ( 2230 ), prescriber percentile ( 2240 ), prescription overlap curve ( 2330 ), prescription overlap percentile ( 2340 ), distribution source curve ( 3130 ), distribution source percentile ( 3140 ) 
         [0053]    The prescription drug use processor is a specially programmed computer device such as a personal computer, a portable phone, a multimedia reproduction terminal, a tablet, a PDA (Personal Digital Assistant), or a dedicated portable terminal that can perform the secure retrieval and processing of input, output, storage and the like of information. It goes without saying that such a program can be distributed through a recording medium such as a CD-ROM and a transmission medium such as the Internet. Further, the present invention may be a computer-readable recording medium such as a flexible disk, a hard disk, a CD-ROM, an MO, a DVD, a DVD-ROM, a DVD-RAM, a BD (Blu-ray Disc), flash drives, thumb drives, and a semiconductor memory that records the computer program. Thus, the distributed program may be used to program a computer to create a prescription drug processor thereby becoming a special purpose computer to securely perform particular functions pursuant to instructions from program software.
