The present application claims benefit to U.S. Application No. 61/780,483 filed on Mar. 13, 2013, entitled “Compliance System that includes a Smart Medicine Container”.
BACKGROUNDMedication non-adherence is a major issue in the health care industry. Numerous studies show high rates of non-adherence directly related to poor clinical outcomes, high healthcare costs, and lost productivity. In the United States, the cost of non-adherence has been estimated at $400 billion annually, which includes $100 billion from avoidable hospitalizations, nursing home admissions, and premature death and $100 billion in lost drug sales. Successful treatment of chronic disease with prescription medication requires consistent use of medicine as prescribed. Yet research shows that medications are not consistently used as directed. Only one out of two patients (50%) takes their medication correctly as prescribed.
Precise and timely electronic medication adherence data collected directly from daily patient medication usage is not yet available. The current state of the art processes prescription billing and health insurance claims data to provide an estimation of medication adherence on a retroactive basis. These methods, called “medication possession ratio” (MPR), and “proportion of days covered” (PDC) are not readily accessible, inaccurate, untimely and after the fact (not actionable). At best, these methods cobble together a single data point from multiple sources offering a one-dimensional snapshot of the days in between the filling and refilling of prescriptions by patients. Medication fills and refills typically last 30, 45, 60, and 90 days, therefore these types of systems and methods can only provide medication adherence estimations 30-90 days after each refill. Furthermore, by processing billing and claims information this method inherently limits the access to this information to users inside the health insurance and pharmaceutical industries and is not useful to patients or caregivers. Knowing the number of days between refills does not provide any insight as to exactly when or why an individual patient did not take medicine as prescribed. Current systems cannot track medication usage precisely and therefore can only supply healthcare systems and caregivers with unreliable estimations of medication adherence.
Non-adherence to medication is not outstandingly the result of forgetfulness. Non-adherence is the result of many different factors, conditions and situations. Some reasons are subjective and emotional. When patients feel better they stop taking their medicine. Other reasons are economic. Patients often split bills to extend prescriptions from 30 to 60 days reducing their costs by half. Some are also medical. Patients very often stop taking medicine when they experience side effects. Complexity of medication therapies also leads to medication adherence failure. Many medication therapies involve six to twenty medications taken at various times of the day. These regimens are extremely complicated and difficult to track. Patients require help from caregivers to manage these regimens. Without precise knowledge of when medications are taken or not, family and caregivers are unable to help prevent non-adherence by supporting, intervening or adjusting medication therapies. Adherence to medication ultimately results in the healthcare industry's ability to communicate, analyze and act upon complex real time medication adherence information in a timely, orchestrated manner.

In embodiments with multiple sensors 24, the sensors 24 may be positioned at the same or different locations. In one embodiment, the sensors 24 are spread around the interior space.
The container 20 may include multiple different sensors 24 to detect the same physical characteristic. By way of example, the container 20 may include two or more orientation sensors 24, or two or more weight sensors 24. The data from the multiple sensors detecting the same aspect may be compared to determine that the data is consistent and reliable. Disparities in the sensors readings for the same physical aspect may indicate that at least one of the sensors is malfunctioning.
One type of sensor 24 detects the weight of the medicine in the interior space. The weight sensor 24 may use load force applied to a surface. The weight sensor 24 may be configured to measure changes in electrical signals based on changes in force, torsion, or load placed on a strain gauge. The weight sensor 24 may be positioned within the interior space and is acted upon by the medication. In one embodiment, the weight sensor 24 is positioned at a bottom of the interior space away from the cap 23. This positioning provides for accurate weight detection when the body 25 is placed in an upright position, such as when it is set on a shelf or counter.
Another sensor 24 detects the volume of the medicine within the interior space. The volume sensor 24 may include various configurations for determining the level of the medicine within the interior space. Volume sensors 24 may be particularly applicable for detecting liquid medicine, although may also have good application for medicine in pill form and powder form. The volume sensor 24 may be configured to detect displacement and/or flow of the medicine to and from the interior space. The volume sensor 24 may also include ultrasonic or optical sensing components to detect a level of the medicine within the interior space. Components for sensing the volume of the medicine include but are not limited to level meters, switches, gauges, tactile sensors, float gauges, and pressure sensors and gauges.
Another sensor 24 detects the motion of the medicine in the interior space and/or the motion of the container 20. Examples of motion sensors 24 include but are not limited to: passive and active infrared sensors; optical sensors including video and camera systems; radio frequency energy sensors using radar, microwave, and tomographic motion detection; sound detection using microphone and acoustic sensors; vibration sensors with triboelectric, seismic and inertia-switch sensors; and magnetism sensors using magnetic sensor or magnetometers. Sensors 24 may also detect one or more different environmental conditions. Examples include but are not limited to temperature sensors 24 and humidity sensors 24.
The sensors 24 may take multiple measurements to obtain accuracy in determining the various physical characteristics of the medicine. In one embodiment, the weight sensor 24 takes readings at about 15-100 times sampling rate per second with a resolution potential of about 0.001 grams. In another embodiment, a volume sensor 24 takes readings at about 15-100 times sampling rate per second with a resolution potential of 0.001 millimeters. In one embodiment, averages of the sensor readings are used in the determination process. In another embodiment, readings that are outside of an expected range are discarded as being bad. These readings may be discarded with the other acceptable readings being used for the calculations. The number of discarded readings may be monitored and notification sent to a remote party in the event the number reaches a predetermined number. This may indicate that the associated sensor 24 is failing.
In containers 20 with a single compartment (e.g.,
The container 20 may include multiple different sensors 24 to detect the same characteristic at different locations and/or times. In one embodiment, the container 20 includes multiple temperature sensors 24. One sensor 24 detects a temperature of the environment for purposes of determining a correction offset as will be explained below. A second sensor 24 detects a temperature in the interior space to monitor temperature of the medicine. A third sensor 24 may detect a temperature at the location of the electrical components to monitor for overheating and possible failure.
The environmental sensors 24 may be used for a variety of different purposes. For example, a temperature sensor 24 may determine one or more temperatures to determine: a temperature of the medication, a temperature of the exterior environment; and a temperature of the electrical components.
The containers 20 include one or more sensing circuits 30 to track medication usage.
The sensing circuit 30 includes a processing circuit 31, including, for example, one or more microprocessors, microcontrollers, Application Specific Integrated Circuits (ASICs) or the like, configured with appropriate software and/or firmware to control the overall operation of the container 20 according to program instructions stored in a memory circuit 32.
The sensing circuit 30 may include one or more different sensors 24 to detect a remaining amount of medication. This may include one or more orientation sensors 24 configured to detect the orientation of the container 20 in one or more different axes X, Y, Z. Other examples of sensors 24 include but are not limited a temperature sensor, motion sensor, volume sensor, and a humidity sensor. The sensors 24 may be positioned in the body 25, in the interior space, or in the attachable cap 23.
In one embodiment, the processing circuit 31 is configured to perform calculations to determine a remaining amount of medication based on one or more signals received from the one or more sensors 24. In other embodiments, the processing circuit 31 is configured to cause the raw sensor readings to be transmitted to a remote location where the calculations are performed to determine a remaining amount of medication indicating the medication usage.
The sensing circuit 30 includes a computer-readable storage medium (shown as memory circuit 32), which stores instructions and/or data needed for operation. The memory circuit 32 may include both volatile and non-volatile memory, for example. Memory circuit 32 may also store orientation information necessary to determine if the body 25 is in the proper orientation for accurately determining the medication.
A communication interface 33 may comprise a short-range wireless interface, such as a BLUETOOTH interface, RFID, ZIGBEE, or WIFI interface, a long range cellular phone or satellite communications interface, or a wired interface, such as a serial, USB, micro USB, FIREWIRE, Lightning, or Thunderbolt interface. There may be more than one communications interface 33. An antenna 39 may be configured for transmitting and receiving wireless signals to and from remote sources (e.g. server 49).
The sensing circuit 30 may include a GPS receiver 34 or other location detector to determine location and history of locations of the container 20. A clock 35 may be associated with the processing circuit 30 that measures the various timing requirements for specific events. The clock 35 may be independent from the processing circuit 30 as illustrated in
The container 20 may also include additional components that are associated with the sensing circuit 30. A display 37 may be configured to display information to the user and/or medical provider. The display 37 may comprise a liquid crystal display (LCD) or an organic light emitting diode (OLED) for example. Additionally, the display 37 may use printed electronic displays, electronic paper displays, or electronic ink technology to provide a thin, flexible and durable display to enable users to view information. An input 38 may provide for a user to enter applicable information. The input 38 may include a variety of formats, including but not limited to one or more buttons, touchpad, and keypad.
The container 20 may also include or control one or more alerting devices for alerting the user of specified events or conditions. The alerting devices may comprise indicator lights that illuminate or generate lighting effects, speakers, beepers, buzzers, or other sound devices; and vibrators or other tactile devices. The alerting devices are controlled by the processing circuit 31 to notify the user when predetermined events or conditions occur. The alerts can be personalized and customized by the user to distinguish the alerts. In one embodiment, alerting device 31 includes an indicator light that is illuminated when the user has not taken their medication within a predetermined time period. The alerting devices may be included in the display 37 to include a message for the patient.
U.S. patent Ser. No. 13/827,373 entitled “Medicine Container with an Orientation Sensor” filed on Mar. 14, 2013, discloses various medication containers that include one or more sensors and is configured to determine a remaining amount of medication within an interior space. This application is herein incorporated by reference in its entirety.
Wireless Communication NetworkThe communication interface 33 of the container 20 as illustrated in
As further illustrated in
The container 20 may also be connected to a nearby device (not shown) through a wired interface, such as a RS 232, USB or FIREWARE interface. Such a device would be configured to access the PDN 55.
The communication interface 33 may also include a Near Field Communication (NFC) interface. Near Field Communication is a short-range wireless connectivity technology that uses magnetic field induction to permit devices to share information with each other over short distances (e.g., on the order of 4 centimeters or less). Communication between two NFC-capable devices is possible when the devices are within close physical proximity to one another, and may be initiated when the devices are actually brought into contact with each other. The distance separating two NFC-capable devices is typically anywhere between about 0 and 4 centimeters, but in some instances can be up to about 20 centimeters.
The container 20 is configured to communicate medication usage information through the PDN 55 to the monitoring server 40. The monitoring server 40 may be configured to provide a web interface 49 as illustrated in
The monitoring server 40 includes one or more processing circuits (illustrated as processing circuit 41) that may include one or more microprocessors, microcontrollers, Application Specific Integrated Circuits (ASICs), or the like, configured with appropriate software and/or firmware. A computer readable storage medium (shown as memory circuit 44) stores data and computer readable program code that configures the processing circuit 41 to implement the techniques described above. Memory circuit 44 is a non-transitory computer readable medium, and may include various memory devices such as random access memory, read-only memory, and flash memory. A communication interface 43 connects the server 40 to the PDN 55, and may be configured to communicate with the PDN 55 according to one or more 802.11 standards. The communication interface 43 may support a wired connection (e.g., Ethernet), a wireless connection, or both. The database 42 is stored in a non-transitory computer readable storage medium (e.g., an electronic, magnetic, optical, electromagnetic, or semiconductor system-based storage device). The database 42 may be local or remote relative to the monitoring server 40. Access to the web interface 49 may be restricted to one or more administrative users 45. A clock 48 may be associated with the processing circuit 41 that measures the various timing requirements for specific events. The clock 48 may be incorporated with the processing circuit 41, or may be a separate component independent from the processing circuit 41. The clock 48 may be configured to measure the specific time during each day, as well as to measure the various time periods (i.e., days, weeks, months, years, etc.).
The monitoring server 40 provides web interface 49 for accessing medication usage information. The web interface 49 may support a website through which the contents of the database 42 are accessible. In one or more embodiments the web interface 49 provides browser-based access to the contents of the database 42. The different entities 60 may login to the browser-based interface and access the pertinent medication usage information. Alternatively, the different entities 60 may obtain medication usage data from the database 42 using one or more Application Programming Interfaces (APIs) through a desktop or mobile client, for example. Also, in one or more embodiments the web interface 49 supports access to the database 42 using web services in addition to, or as an alternative to, the browser-based interface described above.
The different entities 60 may access the information at the monitoring server 40 through a variety of devices 61. The devices 61 may include laptop computers, personal computers, personal digital assistants, mobile computing/communication, tablet devices, and various other-like computing devices. The devices 61 may also include a body-worn device such as a watch or pendant configured to provide access. Each of the entities 60 uses a respective device 61 and accesses the monitoring server 40 through the PDN 55, or alternatively some other network. In one embodiment, one or more of the entities 60 may use his or her respective device 61 to access the server 40 through a separate portal. Each entity's portal may include a secure interface through which the entity may access the information that is assigned to them.
A variety of different entities 60 may have access to some or all of the information at the monitoring server 40. This may include but is not limited to doctors, hospitals, insurance companies, drug manufacturers, pharmacies, patients, family members, patients, and caregivers. The entities 60 may access this information by accessing the server 49. In one or more embodiments, the monitoring server 40 may be configured for browser-based accessibility. The browser-based interface may support well-known browsers such as Internet Explorer and Mozilla Firefox, Safari, Chrome. Alternatively, or in conjunction with the browser-based interface, the monitoring server 40 may provide access to database 42 to requesting APIs over the PDN 55.
Monitoring ServerThe monitoring sever 40 is a robust automated system that analyzes and communicates medication conditions, usage, and adherence data that are collected from the containers 20. The monitoring server 40 monitors, records, and quantifies multiple medication adherence data points providing accurate, comprehensive, and actionable information in real time. The monitoring server 40 also calculates medication usage and tracks and quantifies the effectiveness of the adherence communications between the various entities 60 and the patients 11. By monitoring, analyzing and improving medication adherence performance in real time, the entity 40 provides healthcare and pharmaceutical systems with real time cost savings and intelligence.
The various patients 11 are enrolled into the system 10 by registering with the monitoring server 40 (e.g., via the browser-based interface or with an administrator 45 (e.g., in a non-electronic fashion)). The registration may include the patient 11 providing basic information (e.g., name, age, date of birth), contact information (e.g., phone number, email address, home address). The registration also includes entry of the medication that will be taken and the applicable dose information (e.g., dose time, dose amount, tablet, capsule or liquid form, mass or volume of medication, quantity). In one or more embodiments, the registration process is completed by the patient's healthcare provider or insurance provider. These entities 60 provide the necessary information to the monitoring server 40 to begin monitoring the patient 11. The registration process may also be performed by the patient 11 themselves by accessing the monitoring server 49 through the communications network 50 and entering the necessary information. The registration may also be performed automatically by the monitoring server 40. A healthcare provider or insurance provider may give approval and access to the monitoring server 40 via APIs, so the monitoring server 40 may securely access the healthcare providers' or insurance providers' patient information for registration. The monitoring server 40 does not need to store sensitive and private patient information as long as the monitoring entity 40 has access to the patient information, which can remain stored securely within the healthcare providers' or insurance providers' servers and computing systems. Sensitive and private information such as patient information can also be de-identified (i.e. made anonymous) and/or encrypted. Access to patient data in the database 42 can be restricted to entities that have approved credentials, which can be verified through authentication (e.g., username and password.
The monitoring server 40 and system 10 are configured to track the medication adherence information from a plurality of different patients 11. Each patient 11 may be taking one or more different medications that are stored in one or more containers 20. Real-time medication adherence monitoring is a major advance from the current industry standard of medication possession ratio (MPR) that sifts through prescription claims data to obtain a ratio based upon how many days a user has a prescription on hand. MPR is based on information that may be thirty to ninety days old, is not actionable, and does not capture actual patient medication adherence behavior.
The various compliance calculations performed by the system 10 may occur at one or more locations. This may include one or more calculations performed by the processing circuit 31 integrated with the container 20 and/or the processing circuit 41 of the server 40. This may include the entire processing being performed by the circuit 31 at the container 20, performed by the circuit 41 at the monitoring server 40, or calculations performed by both circuits 31, 41.
Quantifying Medication Adherence Per DoseOne aspect monitored by the system 10 is adherence to medication dose. A dose of medication is defined as the amount of medication to be taken by a patient. The system 10 quantifies adherence to dose by comparing doses taken with doses prescribed. Adherence to a prescribed dose is expressed by a ratio of the actual amount of medication taken compared to the amount of medication prescribed. This ratio quantifies adherence to dose across dose times. Dose time is defined as the prescribed time of day when a dose is to be administered. Dose times can be multiple time periods within a day such as morning, noon, afternoon, evening, bedtime, or breakfast, lunch, dinner. Dose times can also be scheduled as exact times throughout the day. Dose times can also be daily, or per day, or per series of days. Quantifying dose adherence provides healthcare users with a real and actual measure of patient dosing, as well as dose adherence performance and behavior over time. Furthermore, since the system accounts for all doses taken by patients, the system can alert caregivers and patients when too much, or too little medication has been taken.
As an example, a patient is prescribed a medication with a strength of 100 mg per dose, taken four times daily. In oral tablet or capsule form, each tablet equals 25 mg, therefore 4 tablets must be taken to equal the full 100 mg dose. In liquid form, one vial or syringe containing the medication for injection can contain one 100 mg or more doses. Liquid medication can be administered by injection, intravenously, inhalation and orally. The example dose times prescribed or recommended for this medication are for morning, noon, evening and bedtime.
Example 1 Quantifying Medication Adherence Per Dose for TabletsThis example demonstrates how the system quantifies the patient adherence per dose, per dose time for oral medications in tablet or capsule form.
a. Adherence to Morning Dose
-
- Patient takes 4 out of a prescribed 4 tablets
- Adherence to the prescribed dose at this dose time results in a ratio of 4/4, or 1.00
b. Adherence to Noon Dose
-
- Patient takes 3 out of a prescribed 4 tablets
- Adherence to the prescribed dose at this dose time results in a ratio of 3/4, or 0.75
c. Adherence to Evening Dose
-
- Patient takes 2 out of a prescribed 4 tablets
- Adherence to the prescribed dose at this dose time results in a ratio of 2/4, or 0.50
d. Adherence to Bedtime Dose
-
- Patient takes 0 out of a prescribed 4 tablets
- Adherence to the prescribed dose at this dose time results in a ratio of 0/4, or 0.00
e. Adherence to Daily Dose
-
- Patient takes 9 out of a prescribed 16 tablets for the day
- Average adherence and indicator of adherence performance to the prescribed doses results in a ratio of 9/16, or 0.5625 (the average of the four doses)
This example includes a prescription for four doses in a day. The same logic of the adherence monitoring is applied to various other doses (e.g., 1 dose per day, 2 doses per day, etc.). Further, the ratio for determining the adherence to daily dose can be calculated in the same manner for the different variety of daily doses.
Example 2 Quantifying Medication Adherence Per Dose for Liquid MedicationsThis example demonstrates how the system quantifies patient adherence score per dose, per dose time for liquid medications.
a. Adherence to Morning Dose
-
- Patient takes 100 mg out of a prescribed 100 mg dose
- Adherence to the prescribed dose at this dose time results in a ratio of 100/100, or 1.00
b. Adherence to Noon Dose
-
- Patient takes 75 mg out of a prescribed 100 mg dose
- Adherence to the prescribed dose at this dose time results in a ratio of 75/100, or 0.75
c. Adherence to Evening Dose
-
- Patient takes 50 mg out of a prescribed 100 mg dose
- Adherence to the prescribed dose at this dose time results in a ratio of 50/100, or 0.50
d. Adherence to Bedtime Dose
-
- Patient takes 0 mg out of a prescribed 100 mg dose
- Adherence to the prescribed dose at this dose time results in a ratio of 0/100, or 0.00
e. Adherence to Daily Dose
-
- Patient takes 225 mg out of a prescribed 400 mg for the day
- Average adherence and indicator of adherence performance to the prescribed doses results in a ratio of 225/400, or 0.5625 (the average of the four doses)
The system 10 is further configured to calculate and record if the dose taken is more than the dose prescribed. Example 3 provides an example of how the system quantifies patient extra dosing.
a. Tablet Medication Extra Dose
-
- Patient takes a dose of 6 tablets versus a prescribed 4 tablets
- Adherence to the prescribed dose at this dose time results in a ratio of 6/4, or 1.50
- Patient took 6 tablets, 1.5 times more than the dose prescribed
b. Liquid Medication Extra Dose
-
- Patient takes a dose of 150 mg versus a prescribed 100 mg
- Adherence to the prescribed dose at this dose time results in a ratio of 150/100, or 1.50
- Patient took 150 mg, 1.5 times more than the dose prescribed
The system 10 is further configured to determine adherence to medication dose time. Adherence to dosing time and frequency is critical for patients who are prescribed time sensitive medications. Dose time is defined as the prescribed time when a dose of medication is to be taken by a patient. A patient must take their medication within the prescribed dose time in order to be adherent to the dose time. The system 10 qualifies adherence to the dose time by creating a binary score of the dose taken within each dosing time. Dose times can be multiple time periods within a day such as morning, noon, afternoon, evening, bedtime, or breakfast, lunch, dinner. Dose times can also be scheduled as exact times throughout the day. Dose times can also be daily, or per day, or per series of days. The binary adherence scoring method for dose time expresses a definitive indication of dose time adherence: If a patient takes medication within a dose time then the system gives a score of 1 which indicates adherence to dose time (medication taken within a dose time). A score of 0 equals non-adherence to dose time (medication not taken within a dose time).
Example 4A patient is prescribed a medication to be taken four times daily. The example dose times prescribed or recommended for this medication are for morning, noon, evening and bedtime. The patient takes the prescribed dose within the morning dose time; at noon, the patient takes less than the prescribed dose within the noon dose time; in the evening, the patient takes the prescribed dose after the evening dose time but before the bedtime dose time; at bedtime, the patient does not take any dose. The system qualifies the patient adherence to the prescribed medication dose time as follows:
a. Adherence to Morning Dose Time
-
- Patient takes a prescribed dose within the morning dose time
- Adherence to the prescribed dose time is scored 1, or YES (or Adherent)
b. Adherence to Noon Dose Time
-
- Patient takes a partial prescribed dose within the noon dose time
- Adherence to the prescribed dose time is scored 1, or YES (or Adherent)
- NOTE: Patient is adherent to the noon dose time, however, patient is non-adherent to the prescribed dose.
c. Adherence to Evening Dose Time
-
- Patient takes a prescribed dose outside the evening dose time
- Adherence to the prescribed dose time is scored 0, or NO (or Non-adherent)
d. Adherence to Bedtime Dose Time
-
- Patient does not take a prescribed dose within the bedtime dose time
- Adherence to the prescribed dose time is scored 0, or NO (or Non-adherent)
e. Adherence to Dose Time for the Day
-
- Patient is adherent 2 out of 4 dose times
- Average adherence to the prescribed doses results in a ratio of 2/4, or 0.50 (the average of the two dose times)
Absolute adherence to a prescribed medication therapy requires the patient 11 to take the prescribed dose at the prescribed dose time. The system 10 quantifies absolute adherence by creating a binary rating score. If a patient takes the correct dose, within the correct dose time then, the absolute adherence score for this dose time is 1. If a patient does not take the correct dose (no dose, partial dose or extra dose), within the correct dose time, then the absolute adherence score for this dose time is 0, or non-adherent. This absolute adherence scoring method provides a definitive and qualitative measure of adherence to a prescribed medication therapy by totaling all scores over time. An absolute adherence score is determined using the following:
-
- R×D=Prescribed Dose
- D=Dose taken
- DT=Dose Time
- AS=Absolute Adherence Score
- 1=Adherence
- 0=Non-Adherence
- If R×D=D and taken within the scheduled DT, then AS=1
- If R×D=D and taken before or after the scheduled DT, then AS=0
- If R×D≠D and during the scheduled DT, then AS=0
- (If R×D><D and taken within the scheduled DT, then AS=0)
Calculating an absolute adherence rate includes the following: - AS=Absolute Adherence Scores
- DT=Dose Times (or dose days)
- A=Absolute Adherence
A=ΣAS+ΣDT
Assume that the absolute adherence scores for a patient are 1, 1, 0, and 0 for four prescribed doses. The absolute adherence score for the patient over that time period is determined as follows:
A=(AS1+AS2+AS3+AS4)÷4
(1+1+0+0)÷4=0.50
A=0.50
A %=((AS1+AS2+AT3+AT4)÷4)×100
A %=50%
This formula can also be expressed as a long form calculation:
A=absolute adherence rate
n=total number of days the drug is given
m=total number of doses given per day
i=day counter (e.g., i=1, 2, 3 . . . , n days
j=dose counter (e.g., j=1, 2, 3, . . . , m doses per day)
(D·T)i,j equals D·T for the ith day and the jth dose. Where D·T=1 when dosage and time are correct and D·T=0 when dosage, time or both are wrong.
Dividing the double sum by the product of n times m normalizes A so that A=1 represents perfect adherence and A=0 represents no adherence at all. An A=0.5 represents an overall adherence of 50% over the entire dosage regime.
EXAMPLE: Assume drug given bid for three days. Then m=2 and n=3. Expanding the master equation we obtain:
That is, over the entire dosing regimen the patient's overall adherence was 50%.
Example 6A patient is prescribed a medication to be taken four times daily. The example dose times prescribed or recommended for this medication are for morning, noon, evening and bedtime. The patient takes the prescribed dose within the morning dose time; at noon, the patient takes less than the prescribed dose at within the noon dose time; in the evening, the patient takes the prescribed dose after the evening dose time but before the bedtime dose time; at bedtime, the patient does not take any dose.
a. Adherence to Morning Dose Time
-
- Patient takes a prescribed dose within the morning dose time
- Adherence to the prescribed dose event is scored 1 (or Adherent)
b. Adherence to Noon Dose Time
-
- Patient takes a partial prescribed dose within the noon dose time
- Adherence to the prescribed dose event is scored 0 (or Non-adherent)
c. Adherence to Evening Dose Time
-
- Patient takes a prescribed dose outside the evening dose time
- Adherence to the prescribed dose event is scored 0 (or Non-adherent)
d. Adherence to Bedtime Dose Time
-
- Patient does not take a prescribed dose within the bedtime dose time
- Adherence to the prescribed dose event is scored 0 (or Non-adherent)
e. Adherence Rating per Day
-
- Patient is adherent 1 out of 4 dose times
- Average adherence performance rate to the prescribed dose events results in a ratio of 1/4, or 0.25 (average of the four dose times)
- Absolute adherence score for the day is 25%
The adherence information is maintained at the server 41 at the managing entity 40. The information can be accessed by one or more of the entities 60 as discussed above
Alerts and ConversionsAn Alert condition (hereinafter Alert) occurs when the monitoring server 40 detects that the patient 11 has failed to take the proper amount of medication at the proper time. Other Alert conditions may include but are not limited to the patient 11 has taken too much medication, the patient 11 has not taken enough medication, the patient 11 has taken medication during the proper time but not the proper amount, and the patient has taken the proper amount of medication at the wrong time. An Alert may also occur when the monitoring server 41 determines that a remaining amount of medication for the patient 11 is below a predetermined amount. This determination is based on information received from the weight sensor in the container 20.
The monitoring server 40 may be configured to contact and send a notification to the patient or other party upon determining the Alert. The monitoring server 40 may be configurable to select when and how often to contact the patient or other party. In one or more embodiments, the monitoring server 40 contacts the patient or other party at each Alert. The monitoring server 40 may also be configured to contact the patient or other party after a predetermined number of Alerts.
In the event of an Alert, the monitoring server 40 may contact one or more outside persons. For example, this may include just the patient 11 or just the physician. Other examples may include multiple outside persons being simultaneously contacted at the occurrence of an Alert (e.g., contacting both the patient 11 and the caregiver). In one or more embodiments, just the patient 11 may be contacted for a predetermined number of Alerts. Once the predetermined number is surpassed, one or more additional parties are contacted in an attempt to get them to make the patient 11 take their medication.
The monitoring server 40 is configured to provide a variety of information in the notification of an Alert. The notification may include a variety of adherence information such as dose taken, amount of pills, tablets or capsules taken, time when dose taken, difference between the actual dose taken and the dose prescribed, current pill, tablet or capsule count, current amount of medication remaining in container and/or adherence scores. Notifications may also include a history of interactions, notes, surveys, alerts, notifications, results and interventions. Notifications can also include content that can be customized and may include, but not limited to content such as marketing messages, incentives, coupons, discounts, audio files, video files, picture and image files, barcodes, rewards, currency, points, games, and surveys.
The notification may include a variety of different contexts, such as an email, text message, or phone call (based on the patient enrollment information and preferences). Notification may also include sending a signal that activates a light on the container 20, and/or sending a message to the container to be displayed on the container display or digital label and/or played back as an audio or voice message through the container audio and voice speakers. 37. In one or more embodiments, the notification is directly from the monitoring server 40. In other embodiments, the monitoring server 40 provides direct access to alerts and notifications via an application program interface (API). The monitoring server 40 can provide external systems and applications with adherence notifications, alerts and data in real time through APIs. External systems and applications that may use APIs include, but are not limited to healthcare electronic health records, pharmacy systems, pharmaceutical systems, care monitoring systems, hospital systems, medical and healthcare systems, insurance systems, financial systems, analytical systems, software applications, smart phone applications, mobile device applications, and wearable applications. In other embodiments, the monitoring server 40 may contact one or more of a family member, caregiver, pharmacist, physician, care manager or insurance company about the failure of the patient to adhere to their medication regiment and therapy.
An Intervention occurs when the patient 11 is contacted through the system 10 by another party to understand why the patient 11 did not take their medication correctly. This may include contact by one or more of the monitoring server 40, or other outside entity 60. The contact may be a personal visit, phone call (live or recorded message), email message, text message, etc.
The monitoring server 40 tracks the Interventions for each of the patients and their medications 11 by recording a history of all communications made to the patient by the server 40 and additional parties, by recording annotations, surveys and notes of intervention contact, by recording and transcribing phone calls placed from an electronic IP based telecommunications system. Further, the monitoring server 40 tracks medication adherence, refill and intervention conversions after the patient has been contacted as part of an Alert and/or after an Intervention.
A successful Conversion is when the patient 11 complies with an alert notification and or intervention and by performing the instructed medication adherence action within a timeframe, such as taking a dose within a dose time or refilling a prescription within a refill time frame. For example, a successful Conversion occurs when a patient 11 is monitored by the monitoring server 40 and is contacted and notified that she or he needs to take the proper amount of medication, and thereafter, takes the proper amount of the medication and the monitoring server 40 confirms the correct amount of medication taken by the container 20. A successful Conversion can also occur when and a patient 11 is monitored by the monitoring server 40 and is contacted and notified that she or he needs to refill the medication, and thereafter, refills the medication and the monitoring server 40 confirms the correct amount of medication refilled by the container 20. The patient 11 may also be assigned a new container 20 with the refilled medication that may be delivered to or picked up by the patient 11. The monitoring server 40 can also confirm refills by tracking and confirming the receipt of the new containers 20 by the patient 11 refilled with medication. The monitoring server 40 keeps track of successful conversions as a metric of alert, notification and intervention performance.
Similar to Google Ad Words, the content, frequency, timing and effectiveness of alerts, notifications and interventions can be measured and analyzed for performance. Conversions are scored and rated as a ratio of successful conversions against alerts, notifications or interventions. For example, if a particular missed dose alert, notification or intervention results in the correct dose amount taken by the patient 11, and this occurs 10 out of every 10 times then the conversion rate scores a 1.00 or 100%. In contrast, if a different missed dose alert, notification or intervention results in the correct dose amount taken by the patient 11 some of the time, and this occurs 5 out of every 10 times then the conversion rate for this missed dose alert, notification or intervention scores a 0.50 or 50%.
Display InformationThe different entities 60 are able to access the patient information through the monitoring server 40. Upon accessing the monitoring server 40, each entity 60 may be required to enter a passcode to gain access to the information. Further, the information may be stored in a manner in which a particular entity 60 is able to access a limited amount of information.

The various message types may be sent to one or more different recipients via the “Send To” option (column 406). As illustrated in
Each of the message types (column 405) corresponds to one or more triggering events (column 407). In one or more embodiments, an alert message may be caused by a missed dose, overdose, incorrect dose time, and a partial dose taken. An intervention message may be sent due to a missed dose, overdose, incorrect dose time, partial dose, and failed alert to the patient. A confirmation message may be triggered by a correct dose, filled bottle, and an activation. A refill message may be triggered by the detection of various days of medication remaining (e.g., 5 days, 7 days), various pills remaining (e.g., 5 pills, 7 pills), an empty container, and a refilled container. A bottle status message may be triggered by a pill count, low battery, weak signal, and unknown content. A reminder message may be triggered at the time of the dose, and a predetermined time before the dose (e.g., 5 minutes, 10 minutes).
The server 40 is further configured to add messages as illustrated in
Additional recipients may be selected through additional input options 284. These options 284 may include but are not limited to the selection of one or both of a caregiver and a pharmacy.
In one or more embodiments, one or more caregivers may be copied through input of the applicable party input option 284. The message sent to the caregiver is the same message, with the prefix “Sent to [Patient Name]” with the name of the applicable patient included.
MonitorThe main navigation menu 79 includes a Monitor option 180 that provides entities 60 with an interface to view and manage aggregated intervention alerts processed by the monitoring server 40.
In one or more embodiments, entities 60 will typically monitor and keep track of twenty or more patients 11 each having one or more containers 20. As discussed above, the Messaging option 220 is configured to send various messages, including alert, intervention, refill, confirmation and bottle status to the various entities 60 (e.g., patients, family members, caregivers, care managers, care providers, nurses, physicians and pharmacists). The Monitor option 180 aggregates the messages for each entity 60 and provides an interface to view and manage aggregated intervention alerts. Within each alert, the entity 60 can expand the message to view the relevant adherence information and content. Various displays and display options provide the entity 60 with the message content, instructions, contact information, check boxes for quick survey annotations, note pad for annotations and history of intervention actions.
In one or more embodiments, a particular entity 60 is assigned to monitor multiple different patients 11. Each of the patients 11 is assigned to a particular entity 60 when enrolling, or when a new medication container 20 is assigned to them. New entities 60 may be assigned existing patients 11 in a similar manner. In the various embodiments, when the entity 60 signs into the monitoring server 40, the entity 60 is able to access adherence, intervention and conversion information about their patients 11.
In the alert option as illustrated in
The entity 60 is further able to select the other options from the submenu navigation bar 285 to view the corresponding information. The navigation bar 285 remains in each display screen to facilitate navigation through the monitor option 180.
As illustrated in
A call made input 286 may be selected after the entity 60 makes contact with the patient 11. This causes the server 40 to record the interaction in the history and save new inputs, information and/or changes and closes the panel 287. An entity 60 can click the call made input 286 for each call made to patients 11. The server 40 keeps count of the calls made by displaying a phone icon with the call count in the alert row. Once the information has been entered, clicking the alert row 412 closes and collapses the intervention panel 287 and saves any new inputs, information or changes. The information is saved, archived and accessible for further analysis by the server 40 and entities 60.
Entities 60 may use the Monitor option 180 to monitor real time changes in patient medication usage during intervention calls. When an entity 60 makes a missed dose phone call intervention to a patient 11 and the patient 11 takes the correct dose while on the phone with the entity 60. If the correct dose is taken by the patient 11 from the container 20, the container 20 will send the correct does amount to the server 40 and the server 40 updates the missed dose alert as a correct dose in real time so the entity 60 may easily confirm the correct dose taken while still on the phone with the patient 11. The history is also updated in real time.
In one or more embodiments, when using the intervention panel 287, phone numbers will appear as hyperlinks and the entity 60 can tap to make cellular phone calls directly when they are logged onto the server 40 through an enabled phone device 61. In another embodiment, a call patient button may be used to initiate an internet voice call from the Monitor option 180 directly to the patient 11. Voice calls may be recorded as audio files and stored for analysis and records. Voice calls may also be transcribed to provide a transcription of the voice call interventions in the history. Other embodiments may include hyperlinked contacts and/or buttons that initiate voice calls, video calls, text messages, chat, instant messages and emails directly from the Monitor option 180 to the patient 11, patient's family members, caregivers, care providers, care managers and pharmacies.
In one or more embodiments, the history section on the intervention panel 287 displays a log of messages. This displays the day and time, type of message and recipients the messages were sent to. Events logged in history are updated in real time. Each click of the call made input 286, as well as inputs from the survey check list 413, and annotations made in the note pad are also logged and related adherence events and outcomes are displayed in the history.
If a survey answer is checked, the content is preceded with “Reason”; for example if “Just forgot” was checked, the History will display: “Reason: Just forgot”. If multiple surveys are checked then History displays as much content within the limitation of one row and provides a popup or rollover view to display more. If annotations are made, and no survey was checked then History displays as much content within the limitation of one row and provides a popup or rollover view to display more. If subsequent new calls are made with new annotations made as well, then the History logs and displays the newest annotation. If a survey is checked and annotations are made at the same time then history displays the survey with a note icon to click more to view annotations.
One embodiment of the conversion option 414 on the submenu navigation menu 285 is illustrated in
The submenu navigation bar 285 also provides for a non-adherent option 416 as illustrated in
The user may enter a particular row to obtain additional information. If no calls were made during the missed dose time or refill alert then the information in the expanded intervention panel displays “No intervention:” preceding the message content. If calls were made in attempt to convert the missed dose time or refill alert then the information in the expanded intervention panel displays “Unsuccessful intervention:” preceding the message content and the phone icon with call count.
In one or more embodiments, other alerts are moved to the non-adherent tab and archived at the end of each day at 11:59:59 pm (23:59:59). The alert warning icons are replaced with a red “x” box, removed from the alerts tab and moved to the non-adherent tab.
The submenu navigation bar 285 also includes a refill option 417 as illustrated in
The Monitor option 180 may save and archive the various alerts, alert interactions and content. In one embodiment, entities 60 can access alerts per day by using the archive navigator 289 located on the top right of the various displays. The server 40 is configured to display information from a particular date, or from a time range that may span multiple days, weeks, months, etc.
PatientsThe Patients Option 190 on the main navigational bar 79 provides a summary of patients and patient information. In one or more embodiments, patient information may be stored on secure servers external to the server 40. The Patients Option 190 displays patient information by accessing external secure servers through authorized decryption and user authentication protocols. The system 10 is able to decrypt and recouple de-identified patient identities and information to their respective medication adherence data, metrics, charts and records stored on the system 10 servers 49 and databases 42.
In one or more embodiments, the information through the patients option 190 is secured through one or more security levels. The levels may include a first authorized access to allow for access to patient info. This first level requires a first security access as the information may be extremely private, sensitive and highly regulated by the federal government. A second level of access provides for accessing a limited amount of patient information. In one embodiment, the second level of access prevents access to just the medication, duration, and dose information without access to patient information. In one embodiment, the denied information will be crossed-out in the display.
During enrollment of a patient, the applicable information is inputted, such as name, cell phone, address, etc. The server 40 then assigns a patient ID.
The input screen further includes a duration input 421. The duration controls and defines the length of time the server 40 scores and charts the patient adherence. A user input may provide for a menu of options for the duration (e.g., 30 days, 60 days, ongoing, pause). A start input 423 provides for inputting the start date for the medication adherence. User input may provide for a calendar to be displayed to facilitate entry. The start input sets the day when the server 40 starts scoring and charting adherence. An end date input is further provided. In one embodiment, the duration may be set as ongoing which causes the server 40 to automatically input the end date as none. In one embodiment, input of “pause” in the duration input 421 causes the server 40 to stop the adherence scoring at that immediate dose time and date. The scoring can be restarted at which time the server 40 restarts adherence scoring immediately.
Once the patient reaches an end date, the server 40 stops calculating adherence. The running adherence score for the entirety will be displayed in the graph 419 and indicator 420.
A medication section 424 provides for input of the relevant medication data. This may include one or more of the drug name, strength, dosage form, disease, price/refill, count/refill, weight, and prescriber.
The display may include a SMS input 425. The server 40 can be set to turn off sending of text messages to this patient. This may save SMS costs.
The patient information is input while the display is at a patient information setting within input 426. The input 426 may also be set to an archive option to archive patient information. In one embodiment, the archive input deletes the patient and associated information from the input display and stores an archive of the information that includes historic data associated to the patient. This information may include one or more of medication, adherence data, run chart, monitor/alerts/intervention history, messaging, and bottle records. Archived patients can be searchable and retrieved by various information, such as patient ID number, name, drug name and organization. The containers previously used by archived patients will be made available in organization inventory for new patient and new medication use.
RefillsThe Refills Option 200 on the main navigational bar 79 provides a means for tracking refill of medications for each of the patients 11. This option 200 outputs metrics based upon individual medications. In the embodiment of
In one embodiment, an entity 60 can provide an input at the desired medication name causing a breakdown of how the medication performed in each region and how the data rolls up to the larger region (such as the U.S. or Europe).
The server 40 further tracks start date and how long (duration) patients 11 are on each medication. The server 40 calculates and outputs average days patients 11 have possession of each medication. The server 40 also calculates and outputs the average MPR (medication possession ratio).
The server 40 tracks the total number of patients 11 that are on each medication, for each region. The server 40 further tracks the total number of tablets/pills taken by all patients 11 on each medication. The server 40 also tracks how many refills are converted, and also the monetary value of the refills converted. The server 40 also calculates and keeps a running refill conversion score per each medication. The server 40 also calculates and keeps a running average medication adherence score for each group of patients per region.
