RadaR is an application for intuitive, rapid and reproducible quality of care pattern analysis of infectious patients.

Preprint about RadaR available: https://doi.org/10.1101/347534

See a running example here.

Prerequisites for using RadaR

RadaR was built in R , an open source programming language using the Shiny package, a web application framework for R. Users will need to download R in order to use RadaR and we suggest the use of RStudio. R is completely free to use. All required code can be found in this github repositroy.

Input type for RadaR's calculation

RadaR works with standard csv-files (.csv). The variables needed for RadaR are as follows:

Input variables for RadaR

Admission data

Variable Detail
id Patient ID or study ID
adm_id Admission ID
gender Gender
adm_start_date Admission date (YYYY-MM-DD)
adm_end_date Discharge date (YYYY-MM-DD)
death_during_adm Death during admission (TRUE/FALSE)
adm_route Origin at admission
sub_specialty Sub-specialty
specialty General specialty (internal medicine, surgery, other)
birth_date Birth date (YYYY-MM-DD)

Antimicrobial consumption data

Variable Detail
id Patient ID or study ID
ab_start_date Start of antimicrobial treatment (YYYY-MM-DD)
ab_stop_date Stop of antimicrobial treatment (YYYY-MM-DD)
ab_route Administration route (e.g. IV, oral, ...)
atc_code ATC code according WHO ATC classification system
ddd_per_day Defined daily dose of antimicrobial according to WHO ATC classification system per day

Microbiological data

Variable Detail
id Patient ID or study ID
specialty Ordering specialty
antimicrobial susceptibility testing Several columns of tested antimicrobial agents (e.g. amox, cipr etc.) with resistance results (R / I / S)
mo Microbial ID (if test is positive) following the nomenclature of the Integrated Taxonomic Information System
material Test material (currently supported: blood and urine)
test_date Test date (YYYY-MM-DD)
test_number Test number

These data will be loaded, merged, and transformed for analysis upon start of RadaR

Privacy and storage

RadaR works with sensitive hospital data and is based on single observations on the patient level. All data for the running example is simulated and don't represent any real patients.
RadaR can be run locally on protected servers within institutions (for example: Shiny server) or on personal machines (mac, windows, linus).
