Features of the AutoMated tool for Antimicrobial resistance Surveillance System (AMASS).

Feature	Description
Open access	The AutoMated tool for Antimicrobial resistance Surveillance System (AMASS) is open access and can be downloaded [24,25]. The AMASS was developed using R, which is a free software. In the download package for the AMASS (AMASS.zip), there is a folder that contains R-portable and RStudio, which support data processing and analysis to generate the antimicrobial resistance (AMR) surveillance report automatically. The AMASS is under CC-BY 4.0 license. Users can share (copy and redistribute the material in any medium or format) and modify the R codes of the AMASS under the terms and conditions of the Creative Commons license.
User friendly	The AMASS can be run by double clicking on the application icon. Data analysis and AMR surveillance report generation are automated by the AMASS application. Data cleaning, deduplication, and analysis are performed rapidly (it takes about 1-3 minutes to automatically produce an AMR surveillance report using example data sets provided in the AMASS package). No additional program or software is needed. All the essential software is stored in the AMASS package and will operate automatically after double clicking the application file (AMASS.bat). Users do not need to understand R program or write any codes to run the AMASS application.
Highly compatible	The AMASS works with raw data files in either CSV or Excel format, which can be commonly exported from WHONET and other software, programs, or data management systems used for microbiology data and hospital admission data. The AMASS uses data dictionary files (in Excel format) to accommodate data exported from different software, programs, or systems that may have different ways to name data variables and data values. The AMASS dictionary files can be reused by users in the future (eg, monthly, quarterly, and yearly) if the structures of the new raw microbiology data file and hospital admission data file remain unchanged. The AMASS uses a tier-based approach based on availability of raw data files to generate reports. Users with limited data availability (eg, microbiology data with only culture positive results) can still utilize the deduplication and report generation functions of the AMASS. Users with additional data (eg, microbiology data with culture negative results and hospital admission date data) will receive additional reports (eg, sample-based surveillance reports with stratification by infection origin).
High data security	The AMASS does not require the internet for operation. Users do not have to transfer raw individual data (which may contain identifiable information) to any institution outside of the hospital to analyze the data and generate the reports. The AMASS can be run on a standalone computer within the local hospital under local data security. Hence, the AMASS does not increase any risks of breaching individual patient data confidentiality.
Easy-to-use outputs	The automatically generated AMR surveillance report is in PDF format, which is easy to print, read, and share within and outside the hospital.
Easy-to-share outputs	The report (in PDF format) and aggregated summary data files (in CSV format) contain no individual-level patient data and can be readily shared with national and international organizations.
