The SmartTrack System is intended for single-patient use as an electronic data capture accessory for recording and monitoring actuations of prescribed MDI usage. This may be used in the following applications:

In clinical trials, where researchers need to know when a patient has actuated their trial MDI medication;
In clinical practice, where specialists, general practitioners, and nurse educators need to know if a patient has actuated their prescribed MDI medication.
The SmartTrack is not intended to indicate remaining quantity of medication in an MDI and does not include a dose counting function.

Device Description

The SmartTrack System consists of three modules used to provide a compliance monitoring function for use of a Metered Dose Inhaler (MDI).

SmartTrack is a clip-on module that attaches externally around the enclosure of an MDI, using an optical sensor to detect MDI actuation, to log the usage history of the MDI. The device includes an LCD display and control buttons to review basic data and adjust device settings. Various device status conditions are indicated to the user, and logged to provide potentially relevant context for later review of MDI usage history data.
SmartTrack Docking Station is an optical interface cradle used to download data stored on the SmartTrack module, via USB cable connection to a PC, and allow for interaction by the offline software with device settings and status monitoring.
Respiratory Analyzer is a software application for use on a PC that provides for offline review of the MDI compliance data logged by the SmartTrack module. Data is stored in database files with patient, medication, and prescribed dose information, and is available for review and export in various table and graph formats to highlight MDI usage characteristics.

AI/ML Overview

Here's an analysis of the provided text regarding the SmartTrack System's acceptance criteria and studies:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria (Implied)	Reported Device Performance
Functional Verification: Correct logging of MDI actuation data.	"Software verification procedures, with performance testing of the MDI actuation sensor system to ensure data is logged accurately for MDI usage. This established correct functionality of the SmartTrack System according to requirements." (b)(1)
"Hardware testing carried out for the SmartTrack System indicates it meets design and performance functional requirements. Software verification demonstrates that device features are effective, and the system configuration functions equivalently to the predicate devices." (b)(3)
Equivalence to Predicate Devices (Technological Characteristics): Configuration, microprocessor control, internal clock, battery, PC interface for data download, offline review software.	"Technological characteristics of the SmartTrack system are largely equivalent to the predicate devices listed above. Equivalent features between the devices include: configuration in attaching to the outside of an MDI enclosure; microprocessor control and use of an internal clock, to log date and time of MDI actuations; power supply from an internal battery; interface to a personal computer via an optical docking station to download MDI usage data; and offline review software providing for data handling, device interaction, and patient data reporting functions." (a)(6)
Equivalence to Predicate Devices (Sensor Technology Performance):	"The sensor technology used to detect MDI actuation is different from the predicate devices, and this aspect of the device has been verified by non-clinical testing to establish equivalent performance to the predicate devices." (a)(6)
Safety and Effectiveness: Overall device safety and effectiveness.	"This information indicates that the SmartTrack System is equivalent to the predicate devices in terms of device safety and effectiveness." (b)(3).
While not explicitly stated as an "acceptance criterion" with a specific metric, the entire 510(k) submission process is to demonstrate safety and effectiveness for market clearance. The conclusions explicitly state this was achieved through bench testing and equivalence to predicates regarding safety and effectiveness. Pending: "Third party testing of the SmartTrack System for compliance to IEC 60601 series standards for general safety and electromagnetic compatibility, and IEC 60068 series standards for environmental testing, will be completed by an accredited laboratory before marketing of the device." (b)(1)
"The device will meet standard requirements for electrical safety and electromagnetic compatibility before marketing." (b)(3)

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

Sample Size for Test Set: Not specified. The document states "performance testing of the MDI actuation sensor system" was conducted, but no details on the number of devices tested, number of actuations, or the type of MDIs used are provided.
Data Provenance: The testing was "non-clinical testing" and "bench testing." There is no mention of human subjects, geographical origin of data, or whether it was retrospective or prospective. It appears to be entirely laboratory-based.

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

This information is not provided. Given that the testing was hardware and software functional verification (bench testing), it's unlikely that external medical experts were used to establish "ground truth" in the typical clinical sense. The ground truth for actuation detection would have been established by direct observation or automated mechanical means during the bench testing.

4. Adjudication Method for the Test Set

Not applicable/Not specified. As the testing was internal functional verification focusing on accurate data logging from a sensor, a formal adjudication method (like 2+1 or 3+1 used in image interpretation studies) is not described or implied. The "ground truth" for actuation detection would have been determined by the test setup itself.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. The document explicitly states: "Clinical testing was not required to demonstrate the safety and effectiveness of the SmartTrack System. The product functionality has been adequately assessed by bench testing as above." An MRMC study involves human readers, and the submitted information indicates absence of clinical testing involving human evaluation.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

Yes, a standalone (algorithm only) performance assessment was done within the scope of "bench testing." The "performance testing of the MDI actuation sensor system to ensure data is logged accurately for MDI usage" represents the device's standalone performance in detecting and logging actuations. There is no human-in-the-loop component described for this specific performance assessment.

7. The Type of Ground Truth Used

The ground truth for the "performance testing of the MDI actuation sensor system" was likely established through direct observation or mechanical measurement/simulation of MDI actuations during bench testing. For example, actuations could have been manually performed while simultaneously verifying the device's logged data, or automated systems could have repeatedly actuated MDIs, allowing for comparison with the SmartTrack's recorded events. It is not expert consensus, pathology, or outcomes data.

8. The Sample Size for the Training Set

Not applicable/Not specified. This device uses an optical sensor for actuation detection, not a machine learning model that would typically require a "training set" of data in the common sense. Therefore, there's no mention of a training set sample size.

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

Not applicable. As there is no mention of a training set, the method for establishing its ground truth is also not applicable.
