In a still further arrangement the communication may be wireless e.g. Bluetooth or other NFC system.

The sensor system housing 158 or the container 110 may comprise ports to allow access to the memory 155 or battery 157 contained in the respective locations.

As noted above, FIGS. 1 and 2 provide an overview of the entities of the system 1000 of the specification, including some of the data management and processing flows and the management at the support provider side 300 of the devices 110 and various data inputs 220, 240, 260, 270, 290 and outputs.

The key entity of the methods 600 and system 1000 of the specification is the support system 300 or support provider system 300. The support system 300 comprises an information system 350. The information system 350 a computing system including memory and processor. The system 350 comprises a database module 352, processor module 353, and analyser module 355. The system also includes a care provider interface 351 configured to allow a care provider (CP-1, CP-2 . . . CP-N) enter a care plan 310 for POC end users (POC-1, POC-2 . . . POC-N) and to access data relevant to the POC end users who are patients of that care provider. The information system 350 is configured for data management of the user data and use data and data pertaining. The information system 350 also provides for management of data pertaining to the processing of containers and to the processing of container contents 500′.

The system 300 includes a container deployment module 370 where containers 110 are prepared for supply to POC users.

The system 300 includes a returned container processing module 360, where returned containers 110 are received and where the containers 110, data 145, 220, 240, 260, 290 and container contents 500′ are processed.

The processing module includes a first module 362, the receiver module, configured to receive containers. At the receiver module 362, the container identifier 145 may be scanned or read to identify the container and from that the relevant user record. From the user record it is possible to identify the medication type and accordingly the expected contents—i.e. type and number of used delivery devices 500′ contained in that container (medication type being associated with the user record 215 and the identifier 145). Containers 110 may accordingly be pre-sorted or pre-classified for further processing including based on medication type—this allows for processing of similar used medication delivery devices (500′) in batch.

From the first receiver module 362, containers 110 are provided to a second module 363.

In the second stage of processing at module 363, the contents are recovered from a container 110 and the data 220 is recovered. The contents may include the sensor system 150—or battery 157 or memory 156 and the used medication delivery devices 500′.

Processing includes:

• • Reading the identifier 145. The identifier will be/is used to allow the vibration data 220 (use event data) and contents data 240, 260 from the container or associated with the container and to be attributed to the relevant POC user record 215.
  • Opening the container/removal of the lid 117. The lid 117 may be recyclable or reusable and is processed accordingly.
  • Recovery of the stored vibration data 220. The data 220 comprises use event data.
  • The vibration data 220 is sensed by sensor system 150 and stored in a local memory 156 in the container 110 for a sample time period for example during which the container is at the POC site POC-1 or for a sample time period between dispatch of the container and return to the support provider 300.

Data 220 may be recovered by removing the memory 156 or sensor system 150 from the container 110 for docking or connecting to allow recovery of the data 220. Alternatively, the data may be recovered wirelessly. Alternatively, the data 220 may be recovered by docking the container 110 and integrated memory to a docking cradle. The power supply 157 may also be recharged by docking the container to a power supply. As described above, the power supply may be charged using a solar panel attachable to the container. The data recovery and recharging will depend of the arrangement of the sensor system used.

• • Recovery of contents—Analysis of contents—Capture and store data relating to the contents.
    • The containers 110 upon return are expected to contain used medication delivery devices 500′ as deposited therein during the time period that the container was located at the POC side. When a container 110 is opened and emptied the contents 500′ are weighed and imaged. The module 363 includes an imaging system or machine vision system 364 and weighing device 365. As noted above, the module 363 may also include a power supply 366 for recharging and data communication means 367. The image data 240 and weight data 260 are provided along with vibration data 220 and the identifier 145 to the information system 350. The POC use data—including image data 240, vibration data 220, weight data 260 are attributed to the relevant POC user data records. The use data can therein be analysed also in comparison with the relevant care plan 210. The data set 216 for a user for a sample time period that the container is at a point of care) (220 (and/or 270), 240, 260) can also be analysed in comparison with previous data sets 216 for the same user for a previous sample time period.

The image data 240 allows for identification of the used medication delivery devices 500′ received in a container—includes number and types—and for identification of any foreign objects. The weight data 260 provides an indication of the number of items/and is comparable with the image data and care plan data. The expected weight for a particular number of devices 500′ of a particular type will be known. The expected number of devices, weight, type can also be compared with the care plan.

• • In further stages at module 368 the contents 500′ (used medication delivery devices 500′) are processed and the containers 110 are processed.
    • The activity includes the sorting of contents 500′ for recycling, or for the recovery of reusable components. In addition, materials or components that cannot be recycled are processed for waste. The activity may further include the dismantling of the components of the medication delivery devices 500′.
    • The outputs from the processing of the used medication delivery devices 500′ i.e. the components and materials (from the used medication delivery devices 500′) may also be further analysed during processing—e.g. by imaging or weighing at intervals—to allow data collection and for reconciliation of the inputs and outputs for waste management by recycling and for disposal.

The image data comprises a second data set indicative of end user use of medication at the point of care. Essentially, this the image data is a second independent data set in addition to the detected use data. Both the image data and the use data can be considered in analysis of use of medication at the point of care. The image data and use data can be verified against each other.

Similarly, the weight data (relating to the weight of the contents) provides further feedback relating to use of medication on site.

The image data can also be used to classify and sort the returned containers and content for processing in batch. The image data may be user to sort containers or contents. The image data and/or weight data may be used to identify any contaminants.

Further, the containers 110 are processed for re-use. This includes cleaning and/or sterilising and/or inspection. The preparation for re-use may also include the recharging of the power supply and resetting of the sensor system. Some parts of the container may be recycled for example the cover or lid 117.

The container identifier may be scanned or read at one or more of the various steps of processing of the container and container specific data 291 provided (based on the scan/identification of the container at the various stages of processing though the system 360 and 370) to a container record 290. For example, the identifier may be read when he container is returned and data 291 (including for example date and time of return and identifier) may be noted to the relevant container record 290. As noted previously the identifier is read on return also to allow linking of the container contents/use data to a user record 215. Referring also to FIG. 13 data 291 may be captured at various steps of the container processing.

In an exemplary arrangement of the system and method, during the waste processing and removal, the lid 117 is removed from the container 110 automatically, and as the lid is removed, a docking system in the module 363 engages the sensor system 150 and downloads the data 220. The contents 500′ are tipped into a tray for image capture, the image data 240 is paired or associated with the sensor data 220 for analysis and validation also with the prescribed medication schedule of the care plan 210.

The output from the processing of the returned containers 110 content 500′ therefore includes:

• • data—user data 220 (and or user data 270), image 240, weight 260, identifier 145;
  • data pertaining to container processing—data 291—container identifier scanned at selected check points—e.g. when washed—scanned—data 291 captured (data 291 includes one or more of scan station e.g. wash and time, date, identifier—provided to container record 290). Allows verification that container has been processed through all steps.
  • the used medication delivery devices 500′—image 240 of container contents/weight 260 of container contents for a particular container/user—also of the contents as sorted into components and waste—may be imaged and/or weighed at intervals;
  • the container/sensor system/power supply for reuse.

The support provider system 300 comprises a care provider interface 315 to allow care providers (CP-1-CP-N) 1500 to enter care plan 210 including point of care user information 215 and details of the care plan medication information 216 including medication type, schedule etc. The care plan 210 is stored in information system 350.

Referring to FIGS. 1 and 2 and to FIG. 5, the method 610 is described. In an exemplary method 610 of FIG. 5 when a care plan 210 is received, a user record 215 is generated that can be associated with a container for a particular circulation of the container to the user at the POC (for preparing a container 110 for supply to the user) by for example linking the user record 215 to an identifier 145 on the container. The container identifier 145 may comprise a RFID tag (attributable to the user/user record). It will be appreciated that other suitable identifiers may be used.

The method 610 relates to the set-up of a care plan 210 for a point of care end user 215 and preparation of the container 110 for deployment to the POC.

The method includes:

• • receiving 612 at the support provider 300 computer system 350 a care plan 210-1 for a point of care user POC-1;
  • Generating 614 point of care user POC-1 record 215-1 in information system 350 including care plan 210-1 including one or more of: care provider details CP-1, point of care user details POC-1, medication type, medication delivery device system/medication schedule/dose etc. The record will also include identification of container type appropriate to the relevant care plan and indicate the time period that the container is to be on-site at the point of care. Containers of different volume may be provided depending on the anticipated volume of use of medication and medication delivery devices. The record will also include any scheduling and logistical information for providing and collecting a container and for replacing the container.
  • Associate 616 user identifier/user record 215 with identifier 45 on the container 110. This allows for a particular container (and data 220, 240, 260 from the sensor/contents analysis) to be attributed to the relevant end user POC-1 data record 215-1;
  • Provide 618 container 110 to the end user patient at the point of care POC-1;
  • The method may further optionally include for providing reminders 147 or alerts to the end user at the point of care POC-1—for example via sms to their mobile phone. Another communication system or means may also be used if preferred by the patient. Reminders are generated based on the care plan 210 and point of care user record 215.

Referring to FIGS. 1 and 2 and to FIG. 5, the method 630 is described. The method 630 relates the inputs and flows of data relating to the use of medication delivery devices at the point of care.

The method 630 includes:

• • Sensing 631 of movement or vibrations indicative of user interaction with the container 110. The data is detected over a sample period of time while the container is at the point of care. The data provides an indication of use of a medication delivery device based on the detection of disposal of used device 500 into the container.
  • Storing 632 vibration/movement signal data 220 in memory 155 over sample time period;
  • Return 634 of the container to the support provider 300;
  • Retrieval and capture of data 636 relating to use of the container and the contents of the returned container. Data 220 is downloaded from the container, the contents are image to provide image data 240, the contents are weighed to provide weight data 260; the container identifier 145 is read to allow association of the use data 220 and contents data 240, 260 with the relevant user record 215;
  • Providing 638 data 145, 220, 240, 260 to the information system 350 for association with the patient record 215 and care plan 210;
  • Analysis 640 of use data including one or more of vibration movement signal data 220, image data 240 (contents), weight data 260 (weight of contents). Use data may be compared with data relating to the contents. Use and contents data may be compared with the care plan 210 including the expected schedule of use over the sample time period, and the expected contents at the end of the sample time period.

The image data 240 may include for example information identifying the number and type of medication delivery devices 500′ collected in the container 110 at the POC. Device serial numbers relating to devices that have been placed into the container at the point of care during the relevant time period may also be obtained from the image data.

The weight data 260 includes the weight of the overall contents of the device. The recorded image data 240, weight data 260, and use data 220 are associated with the identifier 145 and the relevant user record 215 and care plan 210. The data 220, 240, 260 can be analysed together with the other data also to see if the measured data is in accordance with the expected use data for a care plan. Analysis of the data 220, 240, 260 in comparison also with the care plan 210 provides insights into adherence to medication regimes.

A verification procedure may be performed that reconciles the vibration sensor data 220 including the date and time at which vibrations indicative of use of a medication delivery device occurred, with the prescribed schedule of the care plan 210 to compare the captured use data 220 and expected use data (based on the care plan 210). The use data is further validated by comparison of the data 220 with what was actually in the container i.e. the contents when it was returned, taking account of the image data 240. Clearly the contents data (240, 260) and the use data (220) all relate to the same activities placement of used medication delivery devices into the container 110 over the time period that the container is on location at the point of care

At the point of the care, the container 110 performs various functions including first of all, that of securely collecting and containing used medication delivery devices 500′ for return and processing. The container 110 also provides monitoring at the point of care of interactions with the container, which is detected and stored as data 220 over the relevant time period, the data 220 relates to and is indicative of use of the container and of the medication at the point of care.

As described above, the sensor system 150 is configured to detect activity, interaction, or events at the container 110 by the detection of vibrations or movement using one or more sensors 151 and to output vibration signal data 220, which is stored in memory 155.

Vibration signal data 220 is collected over a pre-determined time period. Vibration signal data 220 may be collected and stored over the entire time period that the container is located at the point or care. Alternatively, the data may be collected and stored over a sample period of time less than the time period on site. Vibration signal data may also be collected and stored between the point in time from when the container is processed and configured for transporting to the point of care, when in location at the point of care and including exchange and return of the container to the-supplier side for processing. The time period may for example be 3 months. This allows for the regular collection and processing of used devices 500′ and data 220, even if the container 110 has not reach capacity. The time period may be set in view of the medication regime and taking account of the number of medication delivery devices 500 expected to be used in a period of time and when the container 110 is expected to be nearly full or nearing capacity. Alternatively, the container size i.e. volume may be selected to support a particular selected time period and taking account of the medication regime.

Referring to FIGS. 7 and 8 some examples of vibration or movement signal data 200 are illustrated. The detected vibrations 220 include those indicative of interaction with the container 110 when a device 500′, such as a used medication delivery device 500′, is inserted into or deposited into the container 110.

The sensor system 150 may also be configured to detect vibrations 220 indicative or movement of transport of the container 110.

The sensor system 150 may also be configured to detect vibration 220 indicative of movement of the container at the point of care.

The sensor system 150 may also be configured to detect background data i.e. when the container is at rest and between interactions with or movement of the device.

The sensor system is configured to output vibration signal data 220, the signal showing detected vibrations and movement.

Accordingly, the activity, e.g. each interaction or each event at the container 110 as indicated by the detection of vibration signals 220, may include vibration signals arising from deposit events, for example where a user contacts a portion of the container to deposit an item into the container, but where the container itself is not moved and the location is not changed. The activity, interaction or event, indicated by detection of vibration signal 220 may include a movement event at the container for example including where the container is moved, lifted, dropped or other such movement interaction which involves a change in location of the container. The activity could also include the opening and closing (or sliding) of an access panel to a allow the deposit event. The activity or event may also include transport where the container is transported between the end-user/point of care site and the container-supplier/processing-site. By testing and calibration, it is possible to identify different types of interactions and events, including the above listed, from a set of data 220 downloaded from the sensor system.

As noted above the sensor system 150 may operate continuously between consecutive occasions that the container 110 is processed and the sensor system 150 and memory 155 reset. Alternatively, the sensor system 150 may operate continuously once the container is located at the point of care. In a further arrangement, the sensor system 150 may be configured to a particular pre-set times, or when interactions with the container 110 are sensed. The vibration signals 220 detected by the sensor system 150 over a time period are stored locally in the container.

The sensor system 150 is configured to detect movement or vibrations, and may comprise an accelerometer 152 configured to detect x, y and z axis movement and to output a signal 220 indicative of the movement that has been detected.

The act of depositing an item such as a syringe or autoinjector pen into the container creates an event vibration signal 225 (the signal shows a signature of the movement or the vibration) as detected by the sensor. The event vibration signal 225 (detected when a used medication delivery device is inserted into the container) has a particular form depending on the vibrations or movement that occur and are detected. The relationship between a particular interaction at the device e.g. depositing an item and the resulting form of the vibration signal may be determined by calibration of the sensor system 200 in the container 110 during different interactions and activity.

In one arrangement according to the specification, the relationship between particular interactions at the container and the resulting vibration signal data 220 is analysed and processed also with the application of machine learning. The system is configured to analyse the vibration signal data 220 of particular users and that of multiple users. This allows for analysis of how the particular user interacts with the device and how the interactions may change over the time period that the container is at the point of care. This also allows for the machine learning of multiple patient interactions to be applied in the analysis of the received data 200. Clearly the data set for a particular time period for a particular user can be compared also with the data sets for that same user for a previous time period or with different users on a similar care plan. Clearly other analyses of the data may also be performed and provided.

The recorded activity data 200 when analysed is compared with the initial care plan data 210 to allow identification of patterns of use or changes etc.

As discussed above, the recorded contents analysis data 240, 260 is also included in further analyses.

When the stored vibration signal data 220 is reviewed or analysed, occurrences of vibration signals 225 (deposit event) as described above are identifiable within the detected signal. The signal data 220 may accordingly be used to determine when used medication delivery device have been deposited into the container, including the date, time, frequency.

The data 220 provides valuable feedback on the user interaction with the container and relating to how the user is adhering to a prescribed medication schedule when the container was located at the point of care.

In the exemplary arrangement when a sensor system 200 is configured to detect a vibration pattern relating to placing an item in the container, then the system is effectively configured to detect vibration signals relating to multiple interactions involving a user placing an item in the container over a time interval. The sensor system detects vibrations as they occur and outputs the vibration signal 220 which is stored in the memory.

When the detected vibration signals 220 are analysed, the analyser determines whether one or more item deposit events are shown in the signal. With reference to sensor data 220 obtained over a period of time, it is further possible to determine the number of item 500′ deposit events, the times, and the frequency of the item deposit events.

Exemplary signals 220, examples of which is shown in FIGS. 7 and 8, are defined by an x-axis, y-axis and z axis signal, shown against time. The deposit event signal, DES, 225 is as peaks against a normal background signal, NBS 226 indicative of the signal detected by the sensor system 200 when the container 110 is at rest and there is no interaction. The event signals 225 represent occurrence detection of unique time limited events—in this case each being a deposit event.

As illustrated with reference to exemplary FIGS. 7 and 8 deposit event signal peaks 225 can be differentiated from background or baseline noise in the signal 226. Accordingly, it is possible to determine from the stored data 220 when (date, time and frequency) an item(s) (such as a syringe or autoinjector or other medication delivery device) were deposited into the container 110, by analysis of the data.

The container 110 may be deployed as a container for directly receiving used medication delivery devices. Alternatively, the container may be removably receivable as an inner container in a medication management device 100.

Referring to FIG. 9, an alternative arrangement of the system (1000). The arrangement is similar to that of FIGS. 1 and 2. In the arrangement of FIG. 8, a device 100 is provided at the point of care. The device 100 comprises a medication use event detection or recordal means 180 configured to detect or record the occurrence of medication use events. The device 100 further comprises a communication means 185 configured to communicate use event data 270 relating to medication use events at the point of case to the information and data management system 350. Data 270 may be communicated in real time or at intervals.

The device 100 may be configured to contain container 110 for collection of used medication delivery devices 500′ at the point of care over a time interval—as described above with reference to the FIGS. 1 to 8. While the container 110 may comprise sensor system 150 which as described above is configured to detect user interaction and data 220, in the arrangement where the device 100 having medication use event detection or recordal means 180, in the arrangement of FIG. 9 the sensor system 150 may be omitted from the container 110.

The other described methods and processing including the processing of returned containers and the capture of image data 240 and weight data 260 pertaining to the contents of the returned container apply to the arrangements of FIG. 9 as to the arrangements of FIGS. 1 and 2.

In the arrangement of FIG. 9, the use data 270 may be provided in the place of use data 220 and provides similar feedback—including times/frequency/of medication use events. The data 270 is attributed to the relevant user record—along with the data 240 and 260—to provide a complete set of data pertaining to use events and contents.

Referring to FIG. 10 method 650—(similar to method 630 of FIG. 6) is described—in this case the use data—as detected by device 100, detector 185 is communicated for example in real-time to the information system 350 by remote communication means. The other steps of the method 650 are similar to those of the method 630.

• • 651 providing POC system 100 including sensor 180 and communication means 185
  • 652 communicating data 270 to system 350. Data 270 detected/communicated stored in information system 350 (associated with user record 215, care plan 210)/
  • 654 Receiving Container 110/contents 500′—container 110 collected and returned to support provider 300
  • 656 Processing container and contents—data 145, 240, 260

  • 660 Analysing of data 240, 260 associated with patient record 215 and care plan 210 and use data 270—comparison of measured and expected data

Further the method of data processing/analysis/management provide for analysis of adherence of user to medication plans, identification of any areas of difficulty for users/provision of support.

Referring to FIG. 11—an illustration of an overview of an arrangement of the information system 350 and inputs and outputs is provided. The figure also shows an exemplary record 215 and the combinations of data inputs.

Referring to FIG. 12—the method 670 shows further detail of data inputs to the system 350 and in particular in relation data management of use data and user data.

Referring to FIG. 13—the method 680 shows further detail of data inputs to the system 350 and in particular relating to the container records 290. The container record 290 for a particular container—may include inputs received as the container is passed through various stages of processing. The container record also information a use counter—which includes the number of times that a container has been circulated to an end user point of care. An upper limit on the maximum number of times a container can be recirculated may be set. It is therefore possible to identify when a container has reached the maximum number of re-circulations. Further it is also possible based on logging of processing of the container at various stages to verify that all the required stages of processing have been completed before a container is provided for re-circulation.

FIG. 14 shows an example of an in-line system for the processing of returned containers 110—based on the methods and systems described above.

• • 1. Registration: Containers are scanned within the process room, identified and weighed.
  • 2. Image Classification: Lids are removed and the container contents are tipped into a transfer chute.
  • 3. Sterilisation: Containers are transferred through a washing station to clean the containers.
  • 4. Water purification: wastewater is pumped to enclosed container for treatment.
  • 5. Relocation: Containers are transferred from processing room to clean room (container data is collected upon transfer).
  • 6. Water Evaporation: containers are moved to air drying location.
  • 7. Re-registration: Containers are scanned and relabelled (as required).
  • 8. Redistribution: Containers are transferred to for redistribution.
  • The container may be scanned at one or more of the steps.

FIG. 15—shows an exemplary—data and container contents 500′ processing flow chart according to arrangements of the specification.

Example 1 An exemplary system 1000 illustrates the application of the systems 300 and methods 600 of the present specification in a home point of care POC setting 1200.

  • 2. The patient is provided with a container 110 fitted with a sensor system 150 including an x, y, z sensor 152. The patient's details, including the prescribed medication schedule, are programmed into an interface or dashboard 351 of the system 300 to define the medication programme and schedule of the care plan 210. The details may include the manufacturer or drug brand. The programme may also include a reminder notification schedule. The system 300 may be configured to remind a patient that they are due to take medication at a particular time. The reminder may be via text or SMS to the patient's smart phone as a reminder. The patient at point of care has a supply of medication and medication delivery devices 500.

  • 5. The patient continues to use the container 110 to dispose of their used medication delivery devices 500′.
  • 6. After 3 months (for example—though it will be appreciated that other time intervals may be selected) a replacement container 110 is sent to the patient and exchanged for the full container.
  • 7. The full container is returned for processing at support provider 300, module 360.
  • 8. The data 220 as detected by the sensor system 150 and stored in the device local memory 155 is downloaded from the sensor system 150.

The data 220 may be stored in a removable memory 155 at the container 110 which is removed from the container 110 when it is received for processing. Alternatively, the data 220 may be communicated from the memory 155 to the data store 352 at the support provider 300 side.

The data 220 provides information on the user interaction with the container 110 indicative of patterns of use of medication at the point of care and relating to adherence to a medication schedule.

Advantageously, the container 110 provides a safe and easy to use point of care device. The container 110 may be used as a self-contained and stand-alone system. The sensor system 150 senses and monitors activity at the container and interactions with the container data 220 sensed over a time period the system 110 is deployed at a point of care is stored for later retrieval and analysis. The sensor system 150 may additionally monitor activity at the container as it is transported between the point of care and point of processing. The sensor may additionally monitor activity at the container as it is processed. The container 110 and sensor system 150 are operable without requiring a network connection or power supply. The device 110 is easy for a patient at the point of care to use—there is no requirement for patient to connect the device to a communication network or power and the location of the device is thus not limited by such requirement. The arrangement of the specification accordingly provides a system and method of the monitoring of interaction and activity or transporting of the container 110 off-line without the requirement for real-time monitoring or a real time data communication connection. The system and method therefore advantageously do not require a network power supply or communication connection.

The method and system of the specification advantageously provides support to the overall arrangement for provision of medication to a patient end-user at point of care. This includes feedback of data relating to adherence to a medication schedule and safe and secure collection and disposal/recycling of used medication delivery devices. The system and method are in particular applied for monitoring and detection of user interaction and the management of the container throughout the cycle of deployment of the container between the container supplier and the user. Effectively there is a provided an arrangement for detecting use events and activity relating to the container.

The systems, methods and container 110 comprising a sensor system of the specification have application including for the following:

• • Medication Adherence—including supporting and monitoring mediation adherence at POC and supporting care providers;
  • Medication use and use medication delivery device disposal habits associated with medication administration;
  • Waste management;
  • Sharps Exchange Service;
  • Patient support services;
  • Medical device collection and recycling;
  • Waste Management and Circular economy;
    • Patient Support Programmes
    • Data insights in Sharps Exchange Programmes
    • Medication Adherence in Injectable therapies
    • Recycling and waste management programme

The device, system and methods of the specification are applied in particular in the management of injectable medication programmes. In such an application, the container comprises a sharps bin for the safe collection and containing of sharps devices. The used medication delivery devices may comprise one or more of an autoinjector, a syringe, sharps or components including needles.

The container device 110 is configured for use in a medication adherence and management support system 1000. In the overall system 1000 the patient/end-user is provided with a container device 110 and medication 500 at point of care. The system 1000 provides for monitoring of medication adherence for example based on a comparison of deposit events 220 indicative of placement of a used medication delivery device 500′ in the container 110. The data relating to placement of used medication delivery device 500′ in the container 110 over a period of time can be compared with a user medication schedule of a care plan 210 to provide an indication of whether the time and frequency of placement of medication delivery devices 500 matches with the schedule and to provide an indication or any deviations. The medication adherence and management system 1000 also provides for management of medical waste including used medication delivery devices.

The investment/cost of providing patient support programmes is often extremely high. Patients with chronic conditions, that administer biological therapeutic drugs in the home require significant support in the form of nurse home visits and 24/7 support, training, medication and disease literature, helplines and waste management services. Accordingly, there is a demand for managing costs while improving levels of care for the patient. Managing waste in a more sustainable manner is also a key driver in new programmes and the ability to provide key data metrics around waste generation, end of life and sustainable waste management is becoming more important. Adherence systems that detect in real time have been described, and while providing high levels of support can be expensive to run as they require communication infrastructure to transmit data across networks. While they provide unique patient insights there is still a cost with running connected services. A non-real time system as described herein provides for collection of use data 220 without the need for more expensive smart connected systems. Data 220 is downloaded once the bin comes back for processing. These systems could provide a relatively nominal cost but have the ability to report on important data points including when the patient used the bin to drop their medication, what was the frequency and the interval. From this, a map of their medication administration timeline and habit is determined. Tracking drop off and collection would also be possible as well as collecting key data metrics on waste generation, such as manufacturer/brand, weight, frequency of bin exchange, recycling and reuse metrics, image capture (returned contents) and actual return (return of container and contents) event.

Data reports 295 showing key insights can be provided to care providers that can show important insights on the behaviour of patients taking medications as well as maintaining effective and streamlined Sharps bin/container 110 exchange programmes. Such a system can also provide additional data insights on waste management and recycling programmes providing environmental data figures such as carbon impact via the recycling or reuse activities.
