In the following detailed description, numerous specific details are set forth to provide a thorough understanding of embodiments of the inventive concept. However, it will be understood by those skilled in the art that embodiments of the inventive concept may be practiced without these specific details. In some instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to obscure the inventive concept. It is intended that all embodiments disclosed herein can be implemented separately or combined in any way and/or combination. Aspects described with respect to one embodiment may be incorporated in different embodiments although not specifically described relative thereto. That is, all embodiments and/or features of any embodiments can be combined in any way and/or combination.
As used herein, the term “provider” may mean any person or entity involved in providing health care products and/or services to a patient.
The term “drug product dispensing system,” as used herein, refers to any type of pharmaceutical or medication dispensing system including, but not limited to, automated systems that dispense vials, bottles, containers, pouches, blistercards, or the like with drug product, semi-automated systems that dispense vials, bottles, containers, pouches, blistercards, strip packages, or the like with drug product, and any combination of automated and semi-automated systems for dispensing a drug product package containing drug product.

Drug product also refers to pharmaceutical alternatives, such as nutraceuticals and/or bioceuticals.
Embodiments of the inventive concept are described herein in the context of a Decision Support System (DSS) that includes one or more Artificial Intelligence (AI) engines for processing patient Quality of Life (QoL) survey information as well as patient clinical information and generating an alert based on changes in the quality of life score for the patient. The embodiments of the DSS are described with respect to the use of one or more machine learning systems. It will be understood, however, that embodiments of the inventive concept are not limited to machine learning implementations of the DSS and that other types of AI systems may be used including, but not limited to, a multi-layer neural network, a deep learning system, a natural language processing system, and/or computer vision system. Moreover, it will be understood that the multi-layer neural network is a multi-layer artificial neural network comprising artificial neurons or nodes and does not include a biological neural network comprising real biological neurons. The AI engines described herein may be configured to transform a memory of a computer system to include one or more data structures, such as, but not limited to, arrays, extensible arrays, linked lists, binary trees, balanced trees, heaps, stacks, and/or queues. These data structures can be configured or modified through the AI training process to improve the efficiency of a computer system when the computer system operates in an inference mode to make an inference, prediction, classification, suggestion, or the like in response to input information or data provided thereto.
Home monitoring technology has allowed providers to keep track their patients' vial information in a timely manner without being limited to collecting such information only during infrequent office visits. In addition to this clinical information, much can be gleaned about a patient's health based on verbal feedback obtained from a patient. While providers can use telehealth sessions to virtually meet and receive feedback from a patient regarding any health problems or concerns the patient may have, these sessions may be difficult and/or expensive to schedule frequently. Some embodiments of the inventive concept may provide a DSS that includes one or more AI engines for processing patient QoL survey information as well as patient clinical information and generating an alert based on predicted changes in the quality of life score for the patient. Separate AI engines may be devoted to different categories of QoL survey answers, such as a health category, an emotion category, and/or an activity category. The AI engine for a particular QoL survey category may generate a prediction in a change of a QoL score for the patient. This predicted change in the QoL score may be compared to a threshold and, based on this comparison, an alert may be generated that is indicative of a possible need for the patient to take action with respect to the patient's health in a particular QoL category.
The alert may be communicated to one or more people designated by the patient. For example, the alert may be communicated to the patient, a caregiver for the patient, a provider, and/or a pharmacist.
To facilitate collecting the survey information, the survey answers may be collected via an Internet of Things (IoT) device, such as a drug product dispensing device that is used by the patient to dispense prescription medications. For example, a patient may have a drug product dispensing system, which serves as an IoT smart hub in the home for dispensing medications in roll, pouches, or the like to assist a patient in remembering times and dosages for taking medications. Such a drug product dispensing system may be further configured to administer a survey to the user with QoL questions covering one or more of the health, activity, or emotion categories to gain insight on the state of the patient's health in one or more of these QoL areas. In some embodiments, the questions used in the survey may be derived from the questions used in the Flanagan Quality of Life Scale (QOLS).
In some embodiments, the patient survey information for a QoL category may be combined with clinical information for the patient, and the AI engine for the QoL category may generate a prediction in a change of a QoL score for the patient based on both the survey information and the clinical information. The clinical information may provide support that helps to clarify one or more of the answers to the survey questions.
Referring to
In some embodiments, the IoT devices 110a, 110b, and/or 110c may be further configured to obtain clinical information from the patients 112a, 112b, and/or 112c, which may also be stored in the database 130. The alert generation server 140 and the QoL alert engine module 145 may, in some embodiments, use both the patient survey information as well as the patient clinical information for training one or more AI models used for assessing patient QoL.
The alert generation server 140 and the QoL alert engine module 145 may be configured to generate a prediction in a change of a QoL score for a patient based on the survey information and, in some embodiments, the clinical information. An alert may be generated based on a comparison of the predicted change in the QoL score for the patient, i.e., a predicted trend in the QoL score, with a threshold. The alert may be indicative of a patient's declining well-being in a particular QoL category, which may benefit from attention or intervention by one or more entities. Accordingly, the alert may be communicated to the patient 112a, 112b, and/or 112c and/or other entities, such as a health care service provider 116a by way of device 114a, a caregiver for the patient 116b by way of device 114b or other entities, such as pharmacists, psychiatrists, family members, and the like.
A network 150 couples the alert generation server 140, the IoT devices 110a, 110b, and/or 110c, the alert recipient devices 114a and/or 114b, and the database 130 together. The network 150 may be a global network, such as the Internet or other publicly accessible network. Various elements of the network 150 may be interconnected by a wide area network, a local area network, an Intranet, and/or other private network, which may not be accessible by the general public. Thus, the communication network 150 may represent a combination of public and private networks or a virtual private network (VPN). The network 150 may be a wireless network, a wireline network, or may be a combination of both wireless and wireline networks.
The QoL alert generation service provided through the alert generation server 140 and the QoL alert engine module 145 to automatically generate one or more alerts based on an assessment of a patients QoL using patient survey information may, in some embodiments, be embodied as a cloud service. For example, patients may integrate their IoT devices 110a, 110b, and/or 110c or other device used to provide survey and/or clinical information the QoL alert generation service and access the service as a Web service. In some embodiments, the QoL alert generation service may be implemented as a Representational State Transfer Web Service (RESTful Web service).
Although
During training mode, the historical patient survey information from the database 130 may be embedded to generate low-dimensional vectors from the high-dimensional survey answer information. For example,
The QoL engines or algorithms 205 may be configured to generate the QoL models 210 for the one or more QoL categories, which are each configured to operate at inference time on new patient survey information from the database 130 to generate an alert based on predicted changes in the QoL score for the patient. Similar to the training operations described above, the new patient survey information and, in some embodiments, patient clinical information, may be embedded using, for example, one-hot encoding, which is provided as input to the applicable one of the QoL models 210, i.e., the QoL model 210 that corresponds to the QoL survey information category. The QoL model 210, which has been trained on historical patient survey information including, in some embodiments, the current patient's historical survey information, may be configured to generate a predicted change in the QoL score for the patient and may then compare this predicted change in the QoL score to a threshold to determine whether to generate an alert indicating that the patient's QoL may be declining in this category to such a extent that additional attention may be warranted. The threshold may be adjusted on a patient-by-patient basis to account for differing patient risk levels.
The at least one core 611 may be configured to execute computer program instructions. For example, the at least one core 611 may execute an operating system and/or applications represented by the computer readable program code 616 stored in the memory 613. In some embodiments, the at least one core 611 may be configured to instruct the AI accelerator 615 and/or the HW accelerator 617 to perform operations by executing the instructions and obtain results of the operations from the AI accelerator 615 and/or the HW accelerator 617. In some embodiments, the at least one core 611 may be an ASIP customized for specific purposes and support a dedicated instruction set.
The memory 613 may have an arbitrary structure configured to store data. For example, the memory 613 may include a volatile memory device, such as dynamic random-access memory (DRAM) and static RAM (SRAM), or include a non-volatile memory device, such as flash memory and resistive RAM (RRAM). The at least one core 611, the AI accelerator 615, and the HW accelerator 617 may store data in the memory 613 or read data from the memory 613 through the bus 619.
The AI accelerator 615 may refer to hardware designed for AI applications. In some embodiments, the AI accelerator 615 may include a machine learning engine configured to facilitate operations associated with an intelligent QoL alert DSS including the various AI engines and AI models described above. The AI accelerator 615 may generate output data by processing input data provided from the at least one core 611 and/or the HW accelerator 617 and provide the output data to the at least one core 611 and/or the HW accelerator 617. In some embodiments, the AI accelerator 615 may be programmable and be programmed by the at least one core 611 and/or the HW accelerator 617. The HW accelerator 617 may include hardware designed to perform specific operations at high speed. The HW accelerator 617 may be programmable and be programmed by the at least one core 611.
The alert DSS module 715 may include one or more QoL algorithm modules 720 and one or more QoL model modules 725. The alert DSS module 715 may be configured to perform one or more of the operations described above with respect to the intelligent alert DSS 200 of

Some embodiments of the inventive concept may provide an intelligent alert generation DSS including one or more AI engines that can be used to process survey information obtained from a patient to predict changes in the patient's QoL score in one or more QoL categories. When a patient's QoL score is trending down by more than a defined threshold, then an alert may be generated to notify the patient and one or more other entities designated by the patient so that attention can be given to any issues that may be negatively impacting the patient's quality of life. In some example embodiments, the survey may be administered by an IoT drug product dispensing hub that the patient uses to control the timing and/or dosage of the patient's medications. This may increase the likelihood that the survey questions are answered on a regular basis, which may improve the assessment of trends in the patient's quality of life in the various categories QoL categories. By assessing a patient's quality of life, a provider may provide improved care to the patient by detecting and addressing areas of the patient's health that may not be easily evaluated based on clinical information alone.
