Study Configuration in Rave®
 Study in Rave® is a collection of eCRFs, folders/visits,
matrices and approved user role permissions which
satisfies the study protocol
 Configuration is simple and can be done with good
training
 As you configure the study, you are building standard
based global libraries. These will enable you to reduce the
overall development time and validation cost
 Carry out the clinical trial in a structured and timely
manner

What is configurable in Rave®?
 UI and solid workflow configuration
 eCRF/folder/matrix design
 Controlled access to eCRFs/data entry
 Edit checks to run the business logic
 Derivations to calculate values
 Custom functions to handle dynamic requirements
 Global library set-up to reuse standard architect elements
Example: eCRFs, fields, variables or matrices…
 Reports configuration adapted to your needs
Example : audit trial report, query detail report and monitor visit report…

Edit Checks and Derivations
What are Edit checks?
 Rule/logic applied on a field in a CRF
 Catching errors earlier in the clinical trial process & improve your data
accuracy
Example : If the VISITDT is empty then fire a Query with message:
The visit date should not be blank
What are Derivations?
 Calculation that derives a value based on the business logic
 Less data entry & automatic calculation
Example : If BIRTHDT and SCRNDT are NotEmpty then Derive AGE field

Limitations of Editchecks and Derivations
Example:
Requirement:
Derive ‘DaysDiff’ field in derivation form with difference between
SCRNDT in screening form and VISITDT in corresponding Day 1,
Day 8 and Day 15 folders
Given:
Cycle is repeated in folder: Cycle 1, Cycle 2, …, Cycle n
Day 1, Day 8 and Day 15 are the folders & exist in all cycles
Derivation is a form & exists in Day 1, Day 8 and Day 15 folders
Enter:

SCRNDT = 01 JAN 2011
Cycle 1>Day 1>VISITDT = 05 JAN 2011 then DaysDiff is derived with
4
Cycle 2>Day 1>VISITDT = 21 JAN 2011 then DaysDiff will be derived
with 20 in Cycle 2>Day 1 and also affect the value in Cycle 1>Day 1

Basic Concepts of Custom Functions

What is a custom function in Rave®?



Custom Function defines the business logic implemented on an eCRF
It can be a C#, Visual Basic or SQL piece of code developed outside of
Rave® and injected into the system to perform an intended action
What experience is needed to develop custom functions?

Study build experience with Rave®

Good knowledge in object oriented programming concepts

Good knowledge of C# and SQL programming

Benefits of Custom Functions
 Configuration of dynamic protocol requirements:





Dynamic query messages and
search lists
Configurable AE/SAE emails
Role/user based emails
Adding/inactivating of
forms/folders/matrices
Copying data

Adding required number of records

Visible/invisible fields

Data comparisons/validations


Standard CFs can be reused for future
study builds
…
Faster Study Build
Improved Data Accuracy
Flexibility allowing more

Categories of Custom Functions
Custom Functions (CFs)can be categorized into:
 Simple CFs
 Moderate CFs
 Complex CFs

Categories of Custom Functions
 Simple custom functions

Very simple business logic

Applied on a single form
Example:
Add a form in the same folder
A few more examples:
Populate or derive data into a field in the same form
Verify the fields data is in a pre-defined format
Display query message or place a sticky within a single
form
Visible/invisible fields in the same form
Adding log records into a form

Categories of Custom Functions
 Moderate Custom Functions

Comparison of multiple forms
Example:
Display query message or place a
sticky based on data from multiple
forms
A few more examples:
Adding log records and populating data into a form
Adding a form in the different folder
Adding folder and adding matrices dynamically
Populate or derive data based on the data in multiple forms
Data comparisons and checking for the chronological order

Requires SQL script
Example:
Generating sequential patient or
randomization numbers
A few more examples:
Subject calendar for the visits
SAE emails based on roles
Checking for uniqueness of the entered data
Dynamic search list

Best Practices
 Use header below to identify and trouble shoot a CF:
 Check for NULL objects
 Check Active status of all objects
 Avoid using try-catches because Rave does it for you

Best Practices
 Keep the code simple and readable…
but if you want to improve system performance:

Use OIDs rather than names

Avoid using foreach

Avoid writing nested for loops
 Loop handling:

Avoid sending emails in a loop

Remember to breakout the loop when search is completed
 Email Handling:

Check the environments before sending an email

Avoid using same email ID for different environments
 Stored Procedure Handling:

Use SQL stored procedures instead of dynamic SQL

Avoid stored procedures for updates or deletions
