Overview

Rules are powerful tools which allow CheckPad to validate data in a flexible way and provide applicable actions once conditions set forth in rules have been met.

These rules cannot be reused among studies or CRFs.

The following guide has the following contents:

Rule structure

Structure and Operation of Rules

Target: Rule's target. This target is usually a data field in a visit CRF of a particular visit
Rule Expression: An expression which evaluate as true or false
Run On (Mode): Mode on which a rule runs
Action: The Corresponding Action to commence when Rule Expression equals defined values

Each rule corresponds to a single action.

Rules with the same target will be aggregated into a rule set.

Operating Mechanism of Rules

When commencing data storage or runs rule in batch mode, the system will search and run all rules based on the current context.

Example: In a data field of a newly created CRF, the system will search and runs all rules with targets being the data fields, and Run on (Mode) as Data Entry.

With each rule, the system will compare the results of Rule Expression and the defined results in rule.

Rule Actions

There are many actions which can be commenced when rule expression returns the correct value:

Discrepancy Notes Action: Create Discrepancy Notes of Failed to Valuation. Check if the data field fails to match input rule in protocol
Email: Send an email to one or many addresses with the message defined in rule
Show Action: Display data fields, data groups specified in rule
Hide Action: Hides data fields, data groups specified in rule
Insert Action: Fill in defined values into a data field specified in rule
Visit Action: Determine the start date of visit defined in rule (can be used to automatically schedule visit)

Data Fields of A Rule

Field	Meaning	Filling instructions
Target	Target to trigger rule. The system will base on this target to search related rules upon save of data or run rules in batch mode	Search and input OID via manual search or use drag and drop to determine the required OID
Run on a Schedule
Run Time	Run monthly on the set time (Only appear if "Run on a Schedule" is selected)	Select the time to run the rules
Rule Expression	Expression used to trigger action in rule	Expression must return true or false. Can be built with the help of Rule Designer dialogue.

Rule List Page

Accessing the page

There are 2 ways to access the rule list page:

Method 1: From the main menu select Task > Manage Data > Rules
Method 2: From the build study select "View" in the Create Rule Row

Screen Layout

The rules list page consists of the following components;

Pagination if the number of rules exceed 10
Buttons to configure the display of the table or download the list
Expand the list (for better view on smaller screens)
List of rules
Filter rules according to corresponding column criteria
Action buttons corresponding for each rule:
1. Edit rules with Rule Designer
2. View Rule details
3. Run Rule
4. Remove Rule
5. Download Rule
6. Test Rule

Create new rule

Create new rule from XML file

Path: Tasks > Build Study > Create Rule > Click on the "+" button

After the system will display a dialogue for the user to import the rules into the system

User selects the 'Choose File' button then choose the appropriate file (file must be in .XML format). The system displays the following notification upon successful import:

User clicks on "continue" to continue importing the rule into the system. After successful import, the system redirects the usual to the initial page: build study page.

Creating rules with rule designer

MedProve encourages CheckPad users to use Rule Designers in editing rules to save time and ensure accuracy in rule creation.
