AMASSplus

Release date: 25th March 2021

The AMASSplus application is an extension of AMASS Version 1.1 that was released on 12 January 2021. AMASSplus has an additional report on selected notifiable bacterial diseases, and the organisms included are:

- Burkholderia pseudomallei
- Brucella spp.
- Corynebacterium diphtheriae
- Neisseria gonorrhoeae

- Salmonella enterica serotype paratyphi
- Salmonella enterica serotype typhi
- Non-typhoidal Salmonella spp.
- Shigella spp.
- Streptococcus suis
- Vibrio spp.

AutoMated
tool for Antimicrobial resistance Surveillance System (AMASS) was
developed as an offline, open−access and easy−to−use application that
allows a hospital to perform data analysis independently and generate
isolate−based and sample−based surveillance reports stratified by
infection origin from routinely collected electronic databases. The
application was built in R, which is a free software environment. The
application has been placed within a user−friendly interface that only
requires the user to double−click on the application icon.

AMASS
performs data analysis and generates reports automatically. The raw
data files required are hospital admission and microbiology databases.
Firstly, the application cleans the microbiology data file and produces
isolate−based and sample−based surveillance reports without
stratification by infection origin. Secondly, the application then
merges the microbiology and hospital admission data files, analyzes the
merged data, and produces an isolated−based and sample−based
surveillance reports with stratification by infection origin. Finally,
the application then perform a statistical analysis to estimate
all−cause mortality of patients with AMR infection and mortality
attributable to AMR, which are automatically added into the AMR
surveillance report.

AMASS aims to support the
local hospitals including those that have only microbiology results
recorded in electronic formats. For example, only isolate−based
surveillance report without stratification by infection origin will be
generated, if only microbiology data file is available and hospital
admission data file is not available in the computer.
