The T1D1 mobile application is indicated for the management of diabetes by people with Type 1 diabetes age 2 and older by calculating insulin doses based on user-entered data.
Prior to use, a healthcare professional must provide the patient target blood glucose values, insulin-to-carbohydrate ratios, and the correction factor (also known as the insulin sensitivity factor) to be programmed into the App software.
The T1D1 application is a user-friendly mobile application designed for Android and Apple devices, specifically catering to individuals aged 2 and above who have Type 1 Diabetes Mellitus (T1DM) and undergo multiple daily injection (MDI) therapy. Its primary objective is to simplify insulin dosing management by providing essential features such as a bolus calculator, a convenient logbook, and various configurable user-specific settings. The T1D1 application is intended to be distributed free of charge and without advertisements while operating independently of any other diabetes care devices. The overarching aim of the app is to streamline the daily calculations required by individuals with T1DM, alleviating the time-consuming and error-prone task of manually calculating and keeping track of insulin dosing.
The key feature of the T1D1 application is the bolus calculator. This calculator implements the standard insulin bolus calculation, taking into account factors such as the user's current blood glucose levels, carbohydrate intake, and target blood glucose levels. By considering these variables, the app provides users with an insulin dose recommendation, which assists in maintaining stable blood sugar levels.
The logbook feature allows users to record, track, and share their diabetes-related information. This information includes blood glucose levels, insulin doses, carbohydrate intake, and other relevant information. The ability to log and share this information with healthcare professionals or family members allows for improved communication and collaboration between individuals with T1DM and their support network.
The T1D1 application offers several presets to simplify the insulin dosing process. These presets can be customized based on individual preferences and needs. By providing preset options, the app eliminates the need for manual input of commonly used settings, saving time and reducing the likelihood of errors. In summary, the T1D1 application is a user-friendly mobile application that assists individuals with T1DM in managing their everyday insulin dosing from day one of their diagnosis.
The provided FDA 510(k) clearance letter for the T1D1 device, while detailing the general process and regulatory compliance, does not contain the specific performance data for the device that would allow for the construction of the requested table of acceptance criteria and reported device performance. The "Performance Data" section on page 10 only lists the standards and guidances followed for risk analysis, software V&V, cybersecurity, and human factors, but does not present any quantitative results from these studies.
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and the reported device performance
- Sample size used for the test set and data provenance
- Number of experts and their qualifications
- Adjudication method
- MRMC comparative effectiveness study details
- Standalone (algorithm-only) performance details
- Type of ground truth used
- Sample size for the training set
- How ground truth for training set was established
To answer these questions, you would need access to the full 510(k) submission, which includes the detailed performance data, verification and validation reports, and clinical study summaries. The clearance letter only confirms that such data was reviewed and deemed acceptable by the FDA for the purpose of granting clearance.
