VisiRule for HealthCare 

WoundCare Medical Expert System Demo

WoundCare is a Medical Expert System demo developed by a medical nurse, with no programming skills, to help manage CPGs for Pressure Ulcer.


The first storyboard illustrates the system being used by a nurse in a hospital accessing the system on a computer on wheels. The nurse is unsure about which dressing to use and is using the system to find an answer. After dressing the wound, the nurse prints the recommendation. The storyboard highlights decision-support and the promotion of continuity of care by storing the recommendation within the patient folder.

Medical Expert Systems

VisiRule is an easy-to-use graphical software tool which enables healthcare professionals and medical practitioners to define and deliver personalised medical advice, diagnosis and treatment guidance and wellness plans online. These are often referred to as Medical Expert Systems or Clinical Decision Support Systems.

VisiRule is based on conditional logic which makes it ideal for representing and executing Clinical Practice Guidelines and medical protocols both online and offline.

The second storyboard shows a nurse using WoundCare on their mobile phone while visiting a patient at home. The assessment indicates that this wound has gotten worse. The system recommends a new dressing, however it also highlights the need to involve a TVN. This highlights the use of the system on a mobile phone and demonstrates elements such as images, links to guidelines and recommendations for further input from other specialists.

Healthcare Expert Systems

Medical Expert System software can be used to help support medical staff adhere to best practice, share specialist knowledge in a easy-to-use way, provide expert knowledge of uncommon areas as well as potentially allow citizens to self-service triage.


In VisiRule, medical knowledge is represented using a simple and intuitive decision tree  flowchart with logical expressions to evaluate the various branches and control the execution flow. VisiRule charts contain a mixture of text, logic, formulae, algorithms, calculations, explanations, definitions, links and graphics. They can be used to capture best practice clinical expertise from healthcare professionals and make it available to a much wider audience in a simple and self-explanatory manner. This is ideal for Medical Flowcharts, Symptom Flowcharts, Clinical Flow charts, indeed anywhere where you have a well-defined structured approach to assessing, diagnosing and treating a medical condition.


VisiRule Author is a dedicated diagramming tool to draw and test charts


VisiRule Publisher compiles the chart to create a questionnaire with code


VisiRule Server executes each question page + the associated rules to compute the following page


VisiRule generates a conclusion + reports, documents & outputs using the answers given

Personalised Advice Generation

Expert advice can be generated and made available for clinicians, patients and medical staff via a collection of interactive, dynamic questions for people to access, anytime, anywhere and on any device. Once set-up, these automated systems are scalable without requiring any additional staff, delivering consistent and trusted advice and guidance while creating a digital record of each session for future reference. This session data can be used downstream to drive other processes such as Electronic Medical Records, workflow automation and report generation.


Medical Calculators & Logical ChatBots

You can use VisiRule not just to capture and validate medical protocols and diagnostics,  implement medical calculators and also to create intelligent logical chatbots.

Medical Diagnosis Expert Systems

Application areas include the assessment of symptoms and provisions of initial diagnosis, treatment suggestions, clinical advice generation, and patient intake automation.


VisiRule Author guides the author in the creation of the medical diagnostic chart and creates the appropriate rules. These can be immediately tested using a dynamic questionnaire which contains all the required questions. When you are happy with your logic, you can upload and publish the chart. The presentation of the questions can be customized using standard web technology. As the user answers the questions, the rules are fired and the logic executed. This directs the user to the relevant diagnostic along with a question/answer trail. A graphic of the chart can be displayed at run-time, like a road map, to help people better understand their journey through the medical process.


This means that non-programmers can rapidly build and deliver intelligent, interactive Clinical Decision Support Systems (CDSS) which give medical advice of a consistent and assured quality.

Medical Expert Systems in Healthcare

VisiRule enables medical teams to improve their internal processes and productivity, and offer automated innovative medical expert systems to patients and other staff. In this way, they can reduce both their costs and risks, whilst improving the service they provide both internally and externally.


It can also free some of your best medical brains from having to deal with the routine drudgery associated with those common yet important tasks, and let them focus on the truly complex challenges which are not so easy to automate.

LPA, the company behind VisiRule, has been in the business of delivering solid, efficient and reliable rule-based systems since 1981 covering areas such as Expert Systems, Knowledge-Based Systems, NLP, CBR and Diagnostic Systems. You can augment VisiRule's basic decision logic with these other AI techniques.
