Health Buddy® Appliance is indicated for use in non-clinical settings to collect and transmit historical medical information to healthcare professionals to help support effective management of their patients.

The Health Buddy Appliance is a communications product that connects to a telephone line or Ethernet connection. It is used by patients in conjunction with the Health Hero Online service to answer questions and furnish information to their healthcare professional(s) between office visits. The Health Buddy Appliance contains software that can be activated to function with specific medical devices (including blood glucose meters, non-invasive blood pressure cuffs, patient weight scales, peak flow meters and pulse oximeters). The Health Buddy Appliance retrieves data from a specific medical device and stores it for transmission to a healthcare provider.

The physiologic patient parameters available for retrospective display and evaluation include pulse rate, blood pressure, blood glucose level, weight, and Peak Expiratory Flow (PEF) and FEV1 (forced expiratory volume) measurements, and blood oxygen saturation (%SpO2). The Health Buddy receives connections from these medical devices, and through the data port, wireless hub, or infrared device, downloads readings from the identified attached device and transmits the responses over the telephone or Ethernet connection at predetermined times to the patient's health care professional.

The Health Buddy Appliance is a simple, user-friendly device that connects to the patient's standard home telephone line. The device connects to a Data Center via a toll-free number or an Ethernet connection to send patient responses since the previous data transfer and to retrieve the new dialogue.

The screen displays information sent by the patient's healthcare provider and asks questions about vital signs, symptoms and behaviors, and allows the patient to respond via four large buttons. The Health Buddy will respond to the patient's answers with education, reinforcement and messages that prompt patient action. The patient responses are sent to the patient's health care provider.

The provided text describes a 510(k) submission for the Health Buddy® Appliance, which is a communication product designed to collect and transmit patient data from various medical devices to healthcare professionals.

Here's an analysis of the acceptance criteria and the study that proves the device meets them, based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't provide specific numerical acceptance criteria for performance metrics (e.g., sensitivity, specificity, accuracy). Instead, it states that "Verification and validation testing activities were conducted to establish the performance, functionality and reliability characteristics of the Health Buddy Appliance." And concludes that "The Health Buddy Appliance performed as intended."

The core "performance" of this device is its ability to communicate and transmit data correctly. The acceptance criteria, therefore, would be that these functions work as expected.

2. Sample Size Used for the Test Set and Data Provenance:

The document does not specify the exact sample size used for the test set or the data provenance (e.g., country of origin, retrospective/prospective). It generally refers to "Verification and validation testing activities."

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:

The document does not mention using experts or establishing ground truth in the context of clinical performance for the test set. This device is an accessory for data transmission, not a diagnostic tool requiring expert interpretation of results. Its performance is evaluated based on its technical functionality (e.g., proper data relay), rather than clinical accuracy adjudicated by experts.

4. Adjudication Method for the Test Set:

Given that the device's function is data transmission and not diagnostic interpretation, an adjudication method for a test set (like 2+1 or 3+1) is not applicable and not mentioned in the document.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

A MRMC comparative effectiveness study is not applicable and not mentioned. The Health Buddy Appliance is not an AI-powered diagnostic tool that assists human readers in interpreting medical images or data. Therefore, there is no "human readers improve with AI vs without AI assistance" effect size to report.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study:

A standalone performance study focused on the algorithm itself was implicitly done through the "Verification and validation testing activities." The software within the Health Buddy Appliance was tested to ensure it correctly handled data retrieval, storage, and transmission. However, the document doesn't quantify this performance with typical standalone metrics like sensitivity or specificity because the device's primary function is communication, not diagnostic interpretation. Its "standalone" performance is its ability to perform its communication tasks correctly.

7. Type of Ground Truth Used:

For the Health Buddy Appliance, the "ground truth" would be related to the correctness of data transmission and device functionality. This would involve:

• Known input data: Inputting specific physiological data from medical devices and verifying that the exact same data is received by the healthcare professional's system.
• Functional specifications: Verifying that all programmed features (e.g., displaying questions, receiving button presses, responding with messages, connecting via Ethernet/phone) work according to their design specifications.
• Electrical and environmental standards: Compliance with relevant industry standards for electrical safety and electromagnetic compatibility.

This is not "expert consensus," "pathology," or "outcomes data" in the traditional clinical sense, but rather a verification against defined technical and functional requirements.

8. Sample Size for the Training Set:

The Health Buddy Appliance appears to be a rule-based or firmware-driven device for data transmission, not an AI/machine learning product that requires a "training set" in the conventional sense. Therefore, the concept of a training set sample size is not applicable and not mentioned in the document.

9. How the Ground Truth for the Training Set Was Established:

As there is no mention of a training set for an AI/ML algorithm, the method for establishing its ground truth is not applicable and not mentioned.

It can retrieve data from an attached medical device (blood glucose meter, non-invasive blood pressure cuff, or patient weight scale) and stores it for later transmission to a healthcare provider.

Based on the provided information, the submission focuses on a modification to the software in the Health Buddy® with Buddylink, not a new stand-alone study to prove effectiveness against specific acceptance criteria. The device is cleared based on substantial equivalence to predicate devices. Therefore, the traditional acceptance criteria and detailed study results, as one might expect for a de novo device, are not explicitly provided in this document.

Here's an attempt to answer your questions based on the available information:

1. Table of Acceptance Criteria and Reported Device Performance

Given that this submission is for a modification to software and relies on substantial equivalence, explicit "acceptance criteria" and "reported device performance" in the quantifiable sense of a clinical trial are not presented. The primary "acceptance criterion" met here is demonstrating substantial equivalence to legally marketed predicate devices.

2. Sample Size Used for the Test Set and Data Provenance

No specific test set or sample size for a performance study is described as this is a substantial equivalence submission for a software modification. The comparison is against predicate devices.

• Sample Size for Test Set: Not applicable / Not provided.
• Data Provenance: Not applicable / Not provided for an independent performance study. The comparison is based on the characteristics and cleared status of the predicate devices.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications

Not applicable. As no independent test set performance data is described, there's no mention of experts establishing ground truth for such a set.

4. Adjudication Method for the Test Set

Not applicable. No discrete test set requiring adjudication is described.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

No, an MRMC comparative effectiveness study was not done or described in this document. The submission is based on substantial equivalence to predicate devices, not improvement over human readers or AI assistance.

6. If a Standalone (algorithm only without human-in-the-loop performance) was done

No, a standalone algorithm performance study is not described. The device is a communication tool, and its function involves human input (data from medical devices, patient responses) and human interaction (healthcare providers receiving data). The evaluation focused on its equivalence as a communication tool.

7. The Type of Ground Truth Used

Not applicable in the context of diagnostic or interpretive performance. The "ground truth" for the device's function is its ability to reliably collect and transmit data, which is implicitly accepted through the substantial equivalence argument to already cleared devices.

8. The Sample Size for the Training Set

Not applicable. This document describes a medical device (hardware with software), not a machine learning algorithm requiring a training set for model development in the sense of AI performance evaluation. The software modification is likely related to connectivity or user interface enhancements rather than a learning algorithm.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as no training set for a machine learning model is mentioned.

Ask a specific question about this device

Health Buddy with Device Connect [Glucose Meter] is indicated for use in non-clinical settings to collect and transmit historical blood glucose meter data to healthcare professionals to help support effective management of diabetes patients.

Health Buddy with Device Connect is intended to be a communication tool to enable healthcare providers to receive patient blood glucose information. The product is intended to be used in conjunction with Health Hero Network Online Service, a communication tool to enable healthcare providers to educate, motivate, and receive patient information. Health Buddy with Device Connect and the Health Hero Network Online Service are not intended to provide automated treatment decisions, nor to be used as a substitute for a healthcare professional's judgment. All patient medical diagnosis and treatment are to be performed under the supervision and oversight of an appropriate healthcare professional.

Health Buddy with Device Connect [Glucose Meter] is indicated for use in non-clinical settings to collect and transmit historical blood glucose meter data to healthcare professionals to help support effective management of diabetes patients.

The provided text describes a 510(k) submission for the Health Buddy® with Device Connect [Glucose Meter], a device intended to collect and transmit historical blood glucose meter data to healthcare professionals. However, the document does not contain any information regarding specific acceptance criteria, a study proving the device meets acceptance criteria, or details regarding device performance metrics.

The document is a US FDA 510(k) summary and the accompanying FDA clearance letter, which focuses on:

• Device Description and Intended Use: Explains what the device does (collects and transmits blood glucose data) and its purpose (to help healthcare professionals manage diabetes patients).
• Substantial Equivalence: States that the device is substantially equivalent to legally marketed predicate devices (LifeScan ONE TOUCH Profile Diabetes Tracking System and LifeScan IN TOUCH Diabetes Management Software). This is the primary basis for 510(k) clearance, rather than a de novo performance study against pre-defined acceptance criteria.
• Regulatory Classification: Identifies it as a Class II device under 21 CFR §862.1345 (Glucose Test System).
• Administrative Details: Contact information, dates, and FDA correspondence.

Therefore, I cannot fulfill your request for:

1. A table of acceptance criteria and the reported device performance: This information is not present in the provided text. The 510(k) clearance is based on substantial equivalence, not a direct comparison against explicit performance acceptance criteria in the provided document.
2. Sample size used for the test set and the data provenance: Not available. No "test set" in the context of a performance study is described.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No ground truth establishment is described.
4. Adjudication method: Not applicable.
5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not mentioned.
6. Standalone performance study: Not mentioned.
7. Type of ground truth used: Not applicable.
8. Sample size for the training set: Not applicable.
9. How the ground truth for the training set was established: Not applicable.

The document is a regulatory submission for substantial equivalence clearance, not a clinical or performance study report that would contain the requested details on acceptance criteria and performance data.
