Reading and Standardizing Automated Insulin Delivery Data

Parses the native exports of several automated insulin delivery (AID) platforms into a common, platform-independent format for continuous glucose monitoring (CGM), basal, bolus, carbohydrate, and self-monitored blood glucose (SMBG) data. Additional functions check completeness, filter, produce visualizations, and convert the data to other formats.

aidR is an open-source R package for reading and standardizing data exported from automated insulin delivery (AID) systems.

AID platforms differ in their file formats, variable names, units, timestamp conventions, and representation of clinically relevant events. aidR maps these heterogeneous exports to a common, analysis-ready format, allowing downstream analyses to be written once and applied consistently across AID systems.

What can aidR do?

aidR provides a common workflow for AID data:

• Read native exports from seven major diabetes management platforms
• Standardize CGM, basal, bolus, carbohydrate, and SMBG data
• Filter CGM and carbohydrate data
• Check data completeness and insulin totals
• Visualize daily glucose, insulin, carbohydrate, and SMBG data
• Merge data across participants and AID systems
• Convert data to DIAX and formats used by iglu and cgmquantify

Supported export formats

aidR currently supports seven export formats:

Installation

Install aidR directly from CRAN:

install.packages("aidR")

or get the latest version from github:

pak::pak("madleina/aidR")

Then load the package:

library(aidR)

Quick start

The main entry point is parse_data(), which reads a subject's AID export and standardizes the major data types into a common format.

library(aidR)

data <- parse_data(
  id = "1",
  paths = "inst/extdata/glooko_example.zip"
)

names(data)
#> [1] "cgm"         "basal"       "bolus"       "SMBG"
#> [5] "carbs"       "total_basal" "total_bolus"

Visualizing AID data

plot_day() provides a daily overview of glucose, insulin delivery, carbohydrate entries, and SMBG measurements.

Contributing

Contributions are welcome. In particular, we welcome support for new AID platforms and updates to existing parsers when export formats change.

Please use the GitHub issue tracker for bugs and feature requests.

[!IMPORTANT] When reporting parsing problems, do not upload identifiable patient data to a public GitHub issue.
