TECHNICAL FIELD
The present disclosure relates generally to systems and methods for communicating a dose history configured for representing an average and a variability of a distribution of injections with a blood glucose regulating medicament applied by a subject with a treatment regimen.
BACKGROUND
Type 2 diabetes mellitus is characterized by progressive disruption of normal physiologic insulin secretion. In healthy individuals, basal insulin secretion by pancreatic β cells occurs continuously to maintain steady glucose levels for extended periods between meals. Also in healthy individuals, there is prandial secretion in which insulin is rapidly released in an initial first-phase spike in response to a meal, followed by prolonged insulin secretion that returns to basal levels after 2-3 hours.
Insulin is a hormone that binds to insulin receptors to lower blood glucose by facilitating cellular uptake of glucose, amino acids, and fatty acids into skeletal muscle and fat and by inhibiting the output of glucose from the liver. In normal healthy individuals, physiologic basal and prandial insulin secretions maintain euglycemia, which affects fasting plasma glucose and postprandial plasma glucose concentrations. Basal and prandial insulin secretion is impaired in Type 2 diabetes and early post-meal response is absent. To address these adverse events, subjects with Type 2 diabetes are provided with insulin medicament treatment regimens. Subjects with Type 1 diabetes are also provided with insulin medicament treatment regimens. The goal of these insulin medicament treatment regimens is to maintain a desired fasting blood glucose target level that will minimize estimated risk of hypo- and hyper-glycaemia. In recent years subjects with Type 2 diabetes have also been treated with liraglutide, long-acting glucagon-like peptide-1 receptor agonist, as an injectable prescription medicine that may regulate and improve blood sugar, and it should be used along with diet and exercise.
Traditional insulin medicament delivery systems have included the use of pump systems that provide a frequent recurrent dosage of insulin medicament. Additional types of delivery systems have been developed, such as insulin pens, which can be used to self-administer insulin medicament treatment regimens in the form of less frequent insulin medicament injections or injections with other types of blood glucose regulating medicaments. A common approach to Type 1 and Type 2 diabetes using such delivery systems is to inject a single short acting insulin medicament (bolus) dosage in a prescribed insulin regimen for the subject in response to or in anticipation of a meal event. In such approaches, the subject injects the short acting insulin medicament dosage shortly before or after one or more meals each day to lower glucose levels resulting from such meals.
A recent development for injection devices, is the development injector systems which are capable of storing dose history (dose size and time), and subsequently sending historical dose data to a mobile phone or computer system. There is a need to effectively visualize this data. The data can be visualized in combination with historical glucose data, in order to draw conclusions about the appropriateness of the dose regimen for desired glucose control.
A common method of representation of glucose data for viewing by a health care provider or patient is the Ambulatory Glucose Profile (AGP), which was developed by clinicians to demonstrate the median level of glucose control as well as an index of variability in control at each hour of a “standard day.” The ability to show both an average glucose value, as well as variability, is an important element of AGP. If the average glucose is higher than the target range, but the variability is also very high, it may be dangerous to address tis by simply increasing insulin dose size, as hypoglycaemia could result. Furthermore, it is known that the existence of high variability in blood glucose can be detrimental, even with an average within range. US 2014/0206970 discloses a method of generating an ambulatory glucose profile window including a graphical display of the glucose data across a modal day.
The visual display presents a modal day (also called standard day, average day) in which all collected data over multiple days are collapsed and plotted according to time (without regard to date) as if they occurred over 24 h, starting and ending at midnight. Smoothed curves representing the median (50th), 25th, and 75th (IQR) and 10th and 90th frequency percentiles define the 24 h AGP, as further described in Journal Diabetes Science Technology, March 2013, Volume 7, Issue 2: pages 562-578.
While clinicians can use this type of visualized data to make some conclusions about the suitability of the current insulin regime being used by the patient, the glucose curve is the output of a number of inputs. An important input, for a diabetic patient, is injections with blood glucose regulating medicaments.

Hereby is provided a multi-shape data structure comprising the functional data structuring the technically extracted information of how the automatically obtained timestamps are distributed, and thereby enabling the technical information to be communicated in a structured way. The multi-shape data structure comprising a multi-shape polygon can be calculated independently of any cognitive content of the single-shape polygons, as the coordinates and the form of the single-shape polygons are automatically provided.

DETAILED DESCRIPTION
The present disclosure relies upon the acquisition of a data set comprising a plurality of blood glucose regulating medicament records taken over a time course. Each respective blood glucose regulating medicament record in the plurality of blood glucose regulating medicament records comprises (i) a respective blood glucose regulating medicament injection event including an amount of blood glucose regulating medicament injected into a subject using a respective injection device in a set of one or more injection devices, and (ii) a corresponding electronic injection event timestamp within the time course that is automatically generated by the respective injection device upon occurrence of the respective blood glucose regulating medicament injection event.
FIG. 1 illustrates an example of an integrated system 502 for the acquisition of such data. The integrated system 502 includes one or more connected injection devices 104, one or more glucose sensors 102, one or more wearable life-style measurement devices (103), memory (not shown), and a processor (not shown). In some embodiments, a glucose sensor 102 is a continuous glucose monitor. In some embodiments, a continuous glucose monitor will be able to timestamp a life-style event, e.g. meal ingestion or fasting period, which the subject engaged in, and therefore it can for this purpose be regarded as wearable a life-style measurement device.
With the integrated system 502, data from the one or more connected injection devices 104, used to apply a treatment regimen to the subject, is obtained as a plurality of insulin medicament records. Each insulin medicament record comprises a timestamped event specifying an amount of injected blood glucose regulating medicament that the subject received as part of the treatment regimen. The time stamped event specifying the amount of blood glucose regulating medicament is automatically obtained in the sense, that the subject or user of the injection device is not required to perform an active step in order to obtain an electronic or digital time stamp and/or an electronic or digital amount of blood glucose regulating medicament. These data are automatically generated by the injection device upon application of injection, i.e., the injection is applied by the subject or user in order to expel an amount of medicament, but the generation of data is provided irrespective of the users intention, when he or she uses the device. Also, in some embodiments, autonomous timestamped glucose measurements of the subject are obtained. In such embodiments, the autonomous glucose measurements are filtered and stored in non-transitory memory. The plurality of blood glucose regulating medicament records of the subject taken over a time course are used to provide a dose history representing an average and a variability of a distribution of the injections applied by the subject. In this way, the blood glucose medicament records are retrieved and communicated in accordance with the methods of the present disclosure.
Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure.

It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.
A detailed description of a system 48, for communicating a dose history representing an average and a variability of a distribution of injections with a blood glucose regulating medicament in accordance with the present disclosure, is described in conjunction with FIGS. 1 through 3. As such, FIGS. 1 through 3 collectively illustrate the topology of the system in accordance with the present disclosure. In the topology, there is a dose history communication device (250) communicating injections performed by a subject who has applied a treatment regimen (206) within a time course (FIGS. 1, 2, and 3), a device for data collection (“data collection device 200”), one or more injection devices 104 for injecting medicaments into the subject, and optionally one or more glucose sensors 102 associated with the subject. Throughout the present disclosure, the data collection device 200 and the dose history communication device 250 will be referenced as separate devices solely for purposes of clarity. That is, the disclosed functionality of the data collection device 200 and the disclosed functionality of the dose history communication device 250 are contained in separate devices as illustrated in FIG. 1. However, it will be appreciated that, in fact, in some embodiments, the disclosed functionality of the data collection device 200 and the disclosed functionality of the dose history communication device 250 are contained in a single device. In some embodiments, the disclosed functionality of the data collection device 200 and/or the disclosed functionality of the dose history communication device 250 are contained in a single device and this single device is a smart phone.
Referring to FIG. 3B, in some embodiments, the treatment regimen (206) comprises a bolus insulin medicament dosage regimen (208) with a short acting insulin medicament (210) or a basal insulin medicament dosage regimen (212) with a long acting insulin medicament (214). In some embodiment the treatment regimen may also comprise a dosage regimen with a medicament comprising a GLP-1 receptor agonist (216) as liraglutide or semaglutide.
Referring to FIG. 1, the dose history communication device 250 communicates a dose history representing an average and a variability of a distribution of injections applied by the subject. To do this, the data collection device 200, which is in electrical communication with the dose history communication device 250, receives a plurality of blood glucose regulating medicament records over a time course, each record comprising (i) a blood glucose regulating medicament injection event including an amount of insulin medicament injected into the subject using a respective injection device 104 in the one or more injection devices, (ii) a respective type of blood glucose regulating medicament (if more than one medicament is applied) injected into the subject from one of short (210) and long acting insulin medicament (214), and alternatively also a medicament comprising a GLP-1 receptor agonist (218), and (iii) a corresponding electronic injection event timestamp that is generated by the respective injection device upon occurrence of the blood glucose regulating medicament injection event. In some embodiments, the data collection device 200 also receives glucose measurements from one or more glucose sensors (e.g., continuous glucose monitors/sensors) 102 used by the subject to measure glucose levels. In some embodiments, the data collection device 200 receives such data directly from the injection devices 104 and/or glucose sensor(s) 102 and/or wearable life-style measurement device (103) used by the subject. For instance, in some embodiments, the data collection device 200 receives this data wirelessly through radio-frequency signals. In some embodiments, such signals are in accordance with an 802.11 (WiFi), Bluetooth, or ZigBee standard. In some embodiments, the data collection device 200 receives such data directly, analyzes the data, and passes the analyzed data to the dose history communication device 250. In some embodiments, an injection device 104, which can be an insulin pen, and/or a glucose sensor 102, and or wearable life-style measurement device (103) includes an RFID tag and communicates to the data collection device 200 and/or the dose history communication device 250 using RFID communication. In some embodiments, the data collection device 200 also receives life-style related event measurements from one or more wearable life-style measurement devices (e.g., meal ingestion sensor measuring a swallowing action, accelerometer measuring exercise etc.) (103) used by the subject to measure the occurrence of a life-style event, the beginning or the ending of such an event and/or to quantify how much the event may affect the blood glucose level of the subject. In some embodiments, the life style measurement device may also generate physiological measurements of the subject (e.g., from wearable physiological measurement devices, or from measurement devices within the data collection device 200 such as a thermometer, etc.).
In some embodiments, the data collection device 200 and/or the dose history communication device 250 is not proximate to the subject and/or does not have wireless capabilities or such wireless capabilities are not used for the purpose of acquiring medicament injection data, autonomous glucose data, and/or life-style related measurement data. In such embodiments, a communication network 106 may be used to communicate insulin medicament injection data from the one or more injection devices 104 to the data collection device 200 and/or the dose history communication device 250, and/or autonomous glucose measurements from the glucose sensor 102 to the data collection device 200 and/or the dose history communication device 250, and/or life-style related event data from one or more life-style measurement devices to the data collection device 200 and/or the dose history communication device 250.
Examples of networks 106 include, but are not limited to, the World Wide Web (WWW), an intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN), and other devices by wireless communication. The wireless communication optionally uses any of a plurality of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), Evolution, Data-Only (EV-DO), HSPA, HSPA+, Dual-Cell HSPA (DC-HSPDA), long term evolution (LTE), near field communication (NFC), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11ac, IEEE 802.11ax, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of the present disclosure.
In some embodiments, the data collection device 200 and/or the dose history communication device 250 is part of an insulin pen. That is, in some embodiments, the data collection device 200 and/or the dose history communication device 250 and an injection device 104 are a single device.
In some embodiments, there is a single glucose sensor 102 attached to the subject and the data collection device 200 and/or the dose history communication device 250 is part of the glucose sensor 102. That is, in some embodiments, the data collection device 200 and/or the dose history communication device 250 and the glucose sensor 102 are a single device.
Of course, other topologies of the system 48 are possible. For instance, rather than relying on a communications network 106, the one or more injection devices 104 and the optional one or more glucose sensors 102 may wirelessly transmit information directly to the data collection device 200 and/or dose history communication device 250. Further, the data collection device 200 and/or the dose history communication device 250 may constitute a portable electronic device, a server computer, or in fact constitute several computers that are linked together in a network or be a virtual machine in a cloud computing context. As such, the exemplary topology shown in FIG. 1 merely serves to describe the features of an embodiment of the present disclosure in a manner that will be readily understood to one of skill in the art.
Referring to FIG. 2, in typical embodiments, the dose history communication device 250 comprises one or more computers. For purposes of illustration in FIG. 2, the dose history communication device 250 is represented as a single computer that includes all of the functionality for communicating a dose history representing an average and a variability of a distribution of injections applied by the subject. However, the disclosure is not so limited. In some embodiments, the functionality for communicating the dose history is spread across any number of networked computers and/or resides on each of several networked computers and/or is hosted on one or more virtual machines at a remote location accessible across the communications network 106. One of skill in the art will appreciate that any of a wide array of different computer topologies are used for the application and all such topologies are within the scope of the present disclosure.

Block 406 represents another step in the method, wherein each of the medicament records 222 are assigned a corresponding single-shape data structure 230. The single-shape data structure 230 is configured for representing a single injection in the distribution of injections in a displayed mode 260, and the graphical displayed mode is illustrated in FIG. 6. The single-shape data structure 230 comprises (i) a corresponding single-shape polygon 231, configured for visualizing a polygon 261 with a two-dimensional shape, in the displayed mode. As illustrated in FIGS. 6A and 6B, the single-shape polygon 231 is configured to be displayed with a first length 262 extending in the first dimension, wherein the first length 262 is having a fixed value, and a second length 263 extending in the second dimension, wherein the second length 263 is having a fixed value (FIG. 6A) or is variable and represents an amount of injected medicament (FIG. 6B). The single-shape data structure 230 further comprises (ii) a corresponding first intensity indicator 232, configured for displaying a first visual property 264 of the single-shape polygon 261, in the displayed mode 260.
FIG. 6, also illustrates that the single-shape polygon 231, can be visualized as a polygon 261 being in the form of a circle (FIG. 6A) and in the form of a rectangle (FIG. 6B). The first visual property 264 is illustrated as a transparency and the intensity can be defined by the corresponding first intensity indicator 232. The first visual property could also be a temperature map, where the intensity indicator 232 would define the intensity. For a low intensity the colour could be blue and for a high intensity the colour could be red.
Block 408 represents another step of the method, wherein the step comprises creating a plurality of consecutive time windows 233 within the time course, wherein each time window 234 is of the same fixed duration, as illustrated on the upper part of FIG. 5.
For each respective time window 234, another step, represented by block 410, comprises creating a set of medicament records 235, and thereby implicitly creating a plurality of sets of medicament records 533 (upper part of FIG. 5). In this way, each respective set of medicament records 235 in the plurality of medicament records 533, comprises a number of medicament records from the first data set 220, and each respective medicament record 222 within the respective set of medicament records 235 have a timestamp 229 in the respective time window 234.

For each respective medicament record 222, within each set of medicament records 235 of the plurality of sets of medicament records 533, the step comprises assigning a corresponding relative time 237 to the respective medicament record 222. For this purpose, the relative time is defined as the relative time within the window 234, e.g., measured as the time from the beginning of the time window to the point in time in the time window indicating the incidence of the injection event. The incidence of the injection in the time window is identified by the time stamp. In this way, the plurality of sets of medicament records 533 represents the distribution of injections.
Block 414 represents another step of the method. For each respective set of medicament records 235, the step comprises superimposing the single-shape polygon 231 from each of the medicament records 224 in the respective set of medicament records 235. The single-shape polygon 231 is superimposed according to the first and the second dimension, as shown in the lower part of FIG. 5. An interval along the first dimension is defined by the fixed duration of the time window, and as a consequence of the polygons being superimposed, two or more superimposed single-shape polygons 231 may overlap within the interval. On FIG. 5, the length in the first dimension for the time window 234 and the length of the interval are not drawn in scale. Also, the relative position of each medicament injection event 224 in the time window in the upper part of FIG. 5, does not drawn to correspond exactly to its relative position in the coordinate system illustrating the superimposition step in the lower part of FIG. 5.
