Summary of MicroGuide™ Benefits

Latest Information

When guidelines are updated new data is made instantly available via the application so clinicians always have the latest version on their mobile app.

Information Access

Clinicians have instant access to local guidelines at the point of care


The application strengthens governance across organisations. All users will be viewing the same guidance in the same format whether via the app or the web-based version. Doctors coming from other hospitals already using this app do not need to learn how to use the app again. Even if the guidelines are different the app will work in the same manner.

Ease of Use

The application is available free of charge to users. It can be downloaded from either Apple’s App Store, Microsoft Store or Google Play. The application is intuitive and easy to use

Rapid Search

Once the application is downloaded, the user selects the appropriate Trust’s guidelines and the latest information is downloaded on to their device enabling rapid search of the right treatment and prescribing advice without the need to be “on-line”. The service includes a “search’ function so that the user can access specific information with just a few keystrokes, as well as a favourites and notes facility.

Drug Calculators

Allows accurate calculations of Creatinine Clearance for Gentamicin and Vancomycin and an Ideal Body Weight calculator.


Using a mobile application provides a Trust with management information such as the number of users, number of times their guideline is downloaded and the number of times it is accessed. In addition, reports will be available on the conditions accessed by users.

Lower Call Rates

Improved and up to date guidelines available, especially for junior doctors, should result in fewer calls and enquiries to the pharmacy team

Desk-Top Access

Published Guidelines are available via the Trust’s intranet for users that do not have access or permission to use mobile devices in the hospital. This is always the most up to date version.


Links can easily be incorporated into the guidelines so that users can access additional information sources easily on their mobile device or contact relevant personnel quickly by e-mail if they have queries.

Printing Costs

The MicroGuide™ solution reduces the need for costly printing and re-printing of pocket guides each time there is a new update.

Timely Update

Changes to guidelines are easily updated via the Portal; this results in changes being made on a more regular and timely basis as the pharmacists know that the doctors and other users of the guideline will get these updates immediately.

More effective to produce

There is no need to design and format guidelines as a standard template is available, allowing hospital teams to focus their time on content.


The service is especially useful as an education tool for junior doctors in Teaching Hospitals. The majority of prescribing errors by foundation trainees in hospitals involve antibiotics and it is estimated that up to 50% of antibiotic prescribing in acute care may be inappropriate.

MicroGuide™ global leader in improving antimicrobial stewardship


MicroGuide™ has established offices in Shanghai and is providing the first medical guidelines mobile platform in China in association with Shenzhen Children’s hospital.

Shenzhen Children’s Hospital is located in the Guangdong Province in China. Since its launch in 1997, the hospital has become one of the best pediatric medical centers in southern China.

MicroGuide™ will continue to be introduced at hospitals throughout China. This growth will support the government’s antimicrobial stewardship directives.



MicroGuide™ continues to be adopted by more and more hospitals throughout the USA. Proving the platform is a valuable tool in improving Antimicrobial Stewardship.

‘Through thoughtful design and implementation of a mobile CDS, our AST is better able to provide cutting-edge clinical recommendations directly to the fingertips of prescribers in our institution.’ IOWA

‘Successful implementation allowed us to broaden the scope of what was initially an antibiogram-focused delivery platform to standardized guidelines for diagnosis and treatment of infections and delivery of infection control and epidemiological information.’ IOWA


MicroGuide™  was introduced into the Angkor Hospital for Children with the support of the Oxford University Medical Research Unit and The Welcome Trust.

MicroGuide™   is opened and accessed over 500 times each month and its use has led to an increasing amount of enthusiasm at the hospital to get involved in stewardship activities, it’s improving knowledge, the working environment, and patient outcomes.


The government of Malawi has a national healthcare service which is government funded, and free to all Malawians at the point of delivery. MicroGuide™ is used by the team of clinicians at The Queen Elizabeth Central Hospital in Southern Malawi town of Blantyre and has around 10,000 adults and 50,000 children patients each year.

‘Following the introduction of MicroGuide™ at Queen Elizabeth Hospital in Malawi, there has been an improvement in antimicrobial stewardship by way of a reduction in the use of broad-spectrum antibiotics and an increase in the number of antibiotic reviews’
Rebecca Lester – Registrar Specialising in infectious diseases


“MicroGuide™ was initially implemented at University Hospital Southampton Trust to distribute Antimicrobial Guidelines to support “Antimicrobial Stewardship”. The objective was to promote adherence to latest prescribing guidelines. The service is now used in over half of all NHS Hospitals throughout the UK. Our reporting evidence clearly shows that MicroGuide™ is in constant use at these Hospitals. We are therefore confident that clinicians are prescribing antibiotics to patients according to evidence based local protocols MicroGuide™ is now used in Trusts, Community Trusts, Clinical Commissioning Groups and Hospitals throughout the world. There are over 100,000 mobile App users in the UK alone accessing up to date information published by trusted sources on a daily basis.


The Irish healthcare system is divided into public and private services. Both services are provided by GPs and the Health Service Executive (HSE) is responsible for providing public and community health services. MicroGuide has been used within Ireland for several years and proved to be an essential tool in improving antimicrobial stewardship.


The Gibraltar Health Authority (GHA) delivers Primary, Secondary and Mental Health Care in Gibraltar to 29,000 residents using a Healthcare model closely linked to the National Health Service (NHS) in the United Kingdom. MicroGuide™ has been successfully used by healthcare professionals on the island since 2016.


In January 2018 we received an order for MicroGuide™ from Landspiitali Hospital, the largest teaching hospital in Iceland. This will be our first ever non-English implementation of MicroGuide™ 

New Zealand

Bay of Plenty was the first District Health Board to use MicroGuide™ in New Zealand, implementing the solution in 2015. They provide services to a population of 214,000 over an area that spans 9,500 sq km. In 2017, Bay of Plenty’s neighbour on North Island, Waikato District Health Board, implemented MicroGuide™. Waikato serves a population of 390,000 and covers more than 21,000 sq km.

Helping regulate prescribing practices to improve antimicrobial stewardship with the world’s number one medical guidelines application

MicroGuide™ consists of five main elements:


The Mobile App

Content Management System

The Web Viewer

Decision Support Module

Technical and Customer support

MicroGuide™ was initially developed to enable pharmacists to create, edit and publish antimicrobial guidelines to their clinicians’ mobile devices so they always had the latest guidance at the point of care.

This objective has since been expanded and our aim now is that MicroGuide™ will facilitate improved and more timely communications between Medical Organisations and their clinicians across a whole range of information sources.

Consequently, in 2015, Horizon released a new version of MicroGuide™ that enables a wide range of guidelines and publications to clinicians’ mobile devices.

Clinicians are able to access all guidelines published via the same Mobile App and therefore only ever have to go to one place to access the latest information.

All published guidelines are also available to view via a Medical Organisation’s Intranet (via the use of our live Web Viewer service); therefore content management of guidelines is simplified, made more effective and only ever needs to be maintained in one place.

MicroGuide™ is now used in Trusts, Community Trusts, Clinical Commissioning Groups and Hospitals throughout the world. There are over 100,000 users globally accessing up to date information published by trusted sources on a daily basis.
