Research project

A digital antimicrobial stewardship smartphone application to combat AMR: the AB-assistant

Status: Ongoing project, start date: February 2018, end date: February 2021

Evaluation of AB-assistant, a smartphone app that is customizable to local guidelines and can be used worldwide, including in low- and middle-income countries

What we do

About our project

Antimicrobials are an indispensable part of modern medicine. However, optimal prescription of these agents is becoming increasingly challenging because of the growing complexity of
guidelines, and constantly changing epidemiology.

AIM
To develop a digital steward for use in different countries worldwide which will increase adherence to prescription guidelines and reduce antimicrobial resistance.

In this project we propose to

  1. develop an AB-assistant app based on the existing Spectrum app (Calgary) with improvements to enhance antimicrobial stewardship in large parts of the world
  2. test the usability of this app in different countries to determine barriers and facilitators
  3. evaluate the AB-assistant in an international, multicentre, randomized clinical trial involving centres in 4 countries in different settings with appropriate antimicrobial use as a primary outcome and
  4. use factors identified in this study to facilitate further customization and worldwide implementation of AB-assistant. 

Our research focus

4 steps have been suggested for development of an optimal IT-based intervention. These steps represent the basis for the division of the different work packages and are:

  • Development
    The basis of the app will be the Spectrum CDSS, which was originally developed in Canada. Using the Spectrum platform, hospitals are able to upload, edit and maintain their own content using a cloud based content management system (CMS) that synchronizes with iOS, Android and Web apps. Each hospital or group of hospitals in the study will customize its own content with local empiric treatment algorithms, local susceptibility data and antimicrobial information relevant to their local formulary. 
  • Feasibility and piloting
    Test the interactive AB-assistant for usability in different countries with different antimicrobial resistance rates and different guidelines in pilot studies. 
  • Evaluation
    Evaluate the impact of the AB-assistant in a multicentre RCT in hospitals in different countries. Alongside the RCT, a process evaluation will be performed to assess actual use of the app and experiences while using it.
  • Implementation and dissemination 
    Develop and implementation plan for more countries with results of the study and international workshops.

Novelty, originality and feasibility of the project
We believe that this study proposal is highly innovative and unique by assessing a customizable app to improve antimicrobial prescribing in many different settings. The multi-country collaboration makes it not only possible to combine expertise in the field of IT-based interventions for AMS, but also to test the app under real-life circumstances in different settings. The project will thus provide an evidence-based framework for antimicrobial management that is 24/7 available on the smartphone of the prescribing physician. Lastly the large expertise of the consortium members with AMS, IT-based intervention, implementation research, behavioral sciences and clinical studies will ensure its feasibility and make this project a possible game changer in the world of AMS.
