    Device Description

    The MedApps Wellness System ("System") is designed to be used by patients to send their data from the LifeScan OneTouch Ultra glucometer to a central server for subsequent storage and display.

    The System is comprised of a "Hub" (cell phone software) and the MedApps Engine, which runs on a central server.

    The Hub is a software program that runs on a cell phone and takes in data from the OneTouch Ultra and then transmits it to the central server for storage and processing.

    The MedApps Engine is a software program that runs on a common Web / Internet secure server platform. The MedApps Engine picks up the stored data sent to it by the Hub and through a set of business rules set by the healthcare providers, determines if a follow-up Interactive Voice Response (IVR) call is required to be made to the patient to collect additional Behavioral information from the patient.

    Once all the data is collected, then it is stored in a repository for access by the healthcare provider,

    The Hub will utilize the OneTouch Ultra integrated Short-range low power wireless transmission (Bluetooth V1.2) or a FDA approved accessory to the medical devices that to transmits the medical device data via Bluetooth to a compatible cellular telephone, such as the Nokia 6620, or other /compatible cellular phones.

    AI/ML Overview

    The provided 510(k) summary for the MedApps™ Remote Patient Monitoring System does not contain the specific details about "acceptance criteria" for performance metrics like sensitivity, specificity, or image quality, nor does it detail a clinical study with such explicit criteria and outcomes for direct comparison.

    However, based on the non-clinical performance data testing and review, and the nature of the device as a data transmission system, we can infer the acceptance criteria and the study's approach to proving substantial equivalence.

    Here's an interpretation of the requested information, drawing inferences where explicit details are not present.

    Acceptance Criteria and Device Performance

    Since the MedApps system is primarily a data collection and transmission device, its performance criteria are centered on its ability to accurately and reliably transfer data. The document does not provide quantitative metrics for accuracy, latency, or data integrity in the form of a table. However, the section on "Non-Clinical Performance Data Testing and Review" implies that the acceptance criteria were based on meeting Software Design Specifications (SDS) and demonstrating functional equivalence to predicate devices.

    Inferred Acceptance Criteria Table:

    Acceptance Criteria CategorySpecific Criteria (Inferred)Reported Device Performance (Inferred)
    Data Transmission:Accuracy/Integrity: Data transmitted from glucometer to Hub and then to central server must be identical to source data.The Alpha validation testing "included testing of all executable code and functionality" and confirmed that the system "met its required requirements and design specifications as intended," which would encompass accurate data transmission.
    Reliability/Completeness: All intended data points are successfully transmitted without loss.The "exhaustive validation scripts of all Software Design Specifications (SDS)" and the "complete record of those executed scripts as operational performance data" suggest that all data points were reliably transmitted as per design.
    System Functionality:Interoperability: Successful connection and data transfer with specified FDA-cleared devices (LifeScan OneTouch Ultra).The system is "fully validated for this intended use" with the LifeScan OneTouch ® Ultra® Blood Glucose Monitoring System, implying successful interoperability.
    User Interface: Software (Hub and MedApps Engine) functions as designed, providing appropriate data display and IVR triggers.Alpha validation "included testing of all executable code and functionality" and demonstrated the system "met its required requirements and design specifications as intended," which would cover user interface and backend functionality related to IVR and data display.
    Security:Data Security: Data transmission and storage are secure.While not explicitly detailed as an acceptance criterion in this section, the mention of "secure server platform" and the overall nature of medical device software validation imply security measures were tested to meet design specifications.
    Hazard Mitigation:All identified software hazards are adequately addressed.Alpha validation included "confirmation that all identified hazards have been adequately addressed by software functionality, the user interface, documentation or user SOP." This indicates that hazard mitigation was a key acceptance criterion and was met during testing.

    Study Details:

    1. A table of acceptance criteria and the reported device performance:

      • (Provided above)
    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):

      • Sample Size: Not explicitly stated. The document refers to "exhaustive validation scripts" and a "complete record of those executed scripts as operational performance data." This suggests a comprehensive test suite rather than a traditional "sample size" in clinical study terms.
      • Data Provenance: Not specified. Given the nature of the device as a software system for data transmission, the "data" being tested would be synthetic or simulated data generated during the validation process to represent real-world glucometer readings. The testing appears to be prospective in the sense that the validation scripts were executed to test the device's functionality. There is no indication of patient-derived data or geographical origin.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):

      • This question is not applicable in the traditional sense. The "ground truth" for a data transmission system is the source data itself. The validation tests would verify that the transmitted data perfectly matches the input data. There is no 언급 of external experts or clinical judgment being used to establish a "ground truth" for the test set, as is common in diagnostic device studies. The "ground truth" here is the expected behavior and output based on the device's design specifications.
    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

      • Not applicable. Adjudication methods like 2+1 (two readers agree, third is tie-breaker) are used in studies involving human interpretation (e.g., radiology reads). For a software device that transmits data, the "test set" verification would involve automated or direct comparison of transmitted data against source data, or verification of functional execution against design specifications. No human adjudication is mentioned or implied.
    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

      • No MRMC comparative effectiveness study was done or is applicable. This device is a data transmission system, not an AI-powered diagnostic tool that assists human readers. Its purpose is to present historical data to healthcare professionals, not to interpret or augment human diagnostic capabilities with AI.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • Yes, implicitly. The "Alpha validation testing" and "exhaustive validation scripts" evaluated the MedApps Wellness System (software algorithm) in isolation to ensure it met its "required requirements and design specifications." This testing focuses on the system's ability to accurately collect, transmit, store, and process data according to its programmed logic, without direct human intervention in the data flow or processing steps. The output data is then presented for human review, but the performance of the transmission system itself is standalone.
    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

      • The "ground truth" for this device's performance testing was its Software Design Specifications (SDS) and the source data (simulated glucometer readings). The validation aimed to confirm that the device accurately processed and transmitted the input data according to its predefined functional requirements and met all specified design parameters.
    8. The sample size for the training set:

      • Not applicable. The MedApps Wellness System is not an AI/ML device that requires a "training set" to learn or optimize its performance. It is a rule-based software system that performs predefined tasks (data collection, transmission, storage, and IVR triggering).
    9. How the ground truth for the training set was established:

      • Not applicable, as there is no training set for this type of device.
