Thinking Outside of the Box – Your eClinical Technology Partner

Looking for an EDC vendor who can be flexible and adapt to your needs rather than forcing you into a cookie-cutter study model? Prelude Dynamics has a solid reputation for being a trusted thought partner – providing custom solutions when the out-of-the-box solution is “almost, but not quite” what is needed for a particular protocol.

We are frequently asked to think “outside the box” and build something new and unique to support our clients and users. These customizations make life easy for clinicians and study managers and can even be done as mid-study updates when new requirements arise during study conduct. Chances are that enhancements requested by one user will also be appreciated by others.

Whether you are conducting a GCP or GLP study, we are here to help you collect and aggregate data in ways that make sense for your unique study – enhancing comprehension and streamlining procedures. Here are a few examples of enhancements and capabilities we have developed in cooperation with our sponsors/CROs in the recent past.

ePRO App – This App helps subjects and pet parents complete forms and surveys remotely and contemporaneously. Not only does this facilitate remote trial participation, it increases data integrity by providing a full audit trail and eliminating the need to transcribe paper forms. The App even supports Visual Analogue Scales that use images as axis labels. How intuitive is that?

Images on VAS scales are more intuitive than words or numbers.
Trial/Site Management – Sponsors/CROs who manage multiple studies have some challenges relating to tracking study startup, site recruitment and meeting enrollment goals. Imagine being able to set up custom checklists and track their completion visually and intuitively. Having a database that contains site credentials, past performance and includes past performance metrics helps get new studies up and running effectively and efficiently.

Custom Summaries – While VISION provides standard summaries such as Enrollment and Form Status, more tailored summaries are often invaluable aids for capturing and summarizing study-specific trends and end points. With custom summaries, there is no need to export data to Excel (or a similar tool) for analysis. Users can access this information directly from within the data collection platform – and be assured they are seeing current data. Personnel summaries can be used to manage and track site clinicians.

Bulk Data Entry – Nobody likes re-entering data that exists in another system or platform. Prelude has worked with our Sponsors/CROs to create configurable upload capabilities that allow spreadsheets of information to be used for task such as:

  • User account creation
  • Site creation
  • Lab results (uploaded for the project and “pushed” to individual subjects)

Do you have an idea for a customization or enhancement that would help you conduct and manage your clinical trial? Reach out and tell us what you need. We stand ready and willing to go the extra mile!

Exciting Updates to the VISION DIY Study Builder!

The VISION 10.8 maintenance release is now available and is being rolled out to live studies. This release includes some much-anticipated enhancements, which were developed to facilitate the experience of both study builders and end users. Let’s look at a few of these in more detail! 

  • Use of images instead of textual labels.
  • IDEXX Labs – configure specific tests for study visit days.
  • Calculation copy feature.
  • Set calculation priority using Drag and Drop.
  • Data encryption at rest.

Use of Images instead of textual labels

Sometimes, a picture is worth a thousand words. VISION now supports the ability to use images to describe data entry fields. End users find images easier to relate to and understand than text, which means they can enter data more efficiently and correctly. These images can also be used in VISION’s ePRO app.

Images on VAS scales are more intuitive than words or numbers.

IDEXX study visit lab configuration

Now you can easily configure the lab tests for each study visit using an intuitive interface. This reduces training requirements for sites and increases protocol compliance.

Calculation copy feature

When specifying calculations for a particular eCRF, it is common to have a set of operations that behave in a similar fashion. Instead of building each calculation from scratch, users can now simply copy an existing calculation and then modify it as needed. This significantly streamlines the time required to program eCRF calculations and increases usability.

Set calculation priority using Drag and Drop.

Until recently, calculation priorities were set using an explicit numeric value. Now users can set an “Auto-Prioritization” attribute – which allows calculation priorities to be set to the order the calculation cards are displayed in. This feature helps form builders gain a quicker and more intuitive understanding of the logic used in form calculations.

Data Encryption at rest

All data in the VISION database is encrypted in transit (e.g., over the internet). It’s now possible to specify that data be encrypted at rest – offering an extra level of security for Protected Health Information.

Introducing the VISION SOP Manager

Why use two different systems to manage clinical data and SOPs?

Organizations who use VISION™ will be interested to know that Prelude Dynamics offers an out-of-the-box SOP Management tool.  This flexible tool is implemented using VISION and supports all the familiar tools and features our user community is familiar with. The SOP Manager fosters compliance by providing notifications in advance of required SOP review dates and is 21 CFR Part 11 Compliant.

The concept of Sites and Subjects is overloaded in the VISION SOP Manager. Sites are SOP Sections and Subjects are SOPs. Two key areas of functionality are supported: SOP Management and SOP Training Records.

SOP Management

SOPs are authored using any standard text editor (i.e., Microsoft Word) that supports change tracking, and a description of revisions is contained within each document. The following process is used to revise an SOP.

  1. With change tracking turned on, a subject matter expert authors/edits the content to comply with current best practices.
  2. The edited source document along with a PDF is uploaded to the SOP’s form.
  3. A different subject matter expert performs a content review of the SOP and electronically signs off on the SOP’s form.
  4. A QA staff member performs a QC review of the SOP and electronically signs off on the SOP’s form.
  5. Once the reviews are done, the SOP is finalized.
The SOP List page contains columns that show the effective date, last review date and next required review date for each SOP. These columns can be used to sort the list page and quickly see which SOPs are due for review in the near future. This helps the quality department stay on top of SOP update deadlines.
There is also a feature that allows users to view all the SOPs that were effective on a certain date. This is especially useful when regulators are interested in knowing the state of the organization’s SOPs when a particular clinical trial was conducted. We use the VISION SOP Manager internally and have noted that auditors find it easy to navigate.

As a bonus, we have an “SOP Management” SOP that we can provide as a template. This template can be used as a baseline and adapted to suit your organization’s process.

SOP Training Records

An important aspect of any organization’s Quality System Management Plan is to record and track staff SOP training. This is done in the context of study users, who each have a demographics form and an annual training form group. This form group contains on-demand forms that can be created for each training session. These on-demand forms are automatically populated with the list of SOPs and are used to record when training on each SOP was completed.

The system supports multiple types of training including “self study”, “group training”, “annual training” and “new employee training”. It also supports an annual training summary for each staff member that facilitates compliance assessment.

Customization Options

While the SOP Management tool can be used “out-of-the-box”, it is natural for organizations to request customizations. Because the tool is implemented in VISION, these can be accommodated in a fast, cost-effective manner. Some popular customization options include:

  • Setting up user roles to match your organization structure.
  • Review cycle requirements (e.g., Annual, Biennial, etc.). Internally, we use Biennial – but this can easily be modified.
  • Custom summaries.


The VISION SOP Management tool is an intuitive and flexible system that is already familiar to VISION users – reducing the training requirements associated with migrating to a new SOP Management tool. It allows organizations to migrate completely away from binders of paper documents and seamlessly integrates staff training – helping to assure compliance.

VISION + IDEXX Labs – a Powerful Partnership

Prelude Dynamics’ VISION™ platform is the only EDC that provides an electronic interface with IDEXX labs – making VISION the preferred EDC in animal health. This interface greatly reduces the errors inherent in manual reporting, which saves clinicians and pet owners time and saves sponsors/CROs money.

IDEXX and Prelude Dynamics - a Powerful Partnership

IDEXX recently upgraded their Laboratory Information Management System (LIMS) to include some backend improvements as well as a new customer-facing feature that will clarify some aspects of reporting. Prelude and IDEXX developed and conducted a formal validation on this improved interface in a collaborative fashion – ensuring future smooth operations.

Previously, IDEXX provided the following flags with each reported lab result:

  • Normal – the result was within normal ranges.
  • High – the result was higher than normal.
  • Low – the result was lower than normal.
  • None (blank) – an observation for which there is no normal range.

IDEXX High/Normal/Low Flags

An additional flag of “Not Applicable” has been added and is now used for results of “Do Not Report” (DNR) or “Quantity Not Sufficient”, which were previously not flagged. This new flag will serve to alert clinicians when samples should be re-taken (or other appropriate action) and lessen the chance they will overlook these findings and assume they are normal.

New IDEXX "Not Applicable" Flag for results
Prelude Dynamics and IDEXX continue to be committed to improving the efficiency and accuracy of clinical data and streamlining clinical research.

VISION™ Incorporates AI Technology for Monitors

Study Monitors have a lot on their plates. While VISION’s automated data cleaning capabilities make their jobs easier, we thought it be useful to provide them with a tool that would automatically flag database fields that are more “challenging” for sites to complete. Our new AI Monitoring Enhancement Engine (AIMEE) does just that. When monitors are reviewing a form, they can turn AIMEE on with a single click of the mouse and instantly focus on database fields that are historically known to require attention.

A single click of an icon turns on AIMEE.

AIMEE calculates a score for each field and highlights those that require attention.

AIMEE calculates a score for each field and highlights those that require attention.

How does it work? AIMEE learns over time and calculates a risk score for each field on the form, and highlights those that merit further scrutiny. What is this score based on? AIMEE looks across all instances of the form in the study and considers the number of changes, queries, comments, and occurrences of errors and warnings for each field on the form. It uses that information to generate a score, which is intuitively displayed next to each field on the eCRF. Low scores are “good” and high scores are “concerning”.

AIMEE works well in conjunction with VISION’s field-by-field review functionality – which monitors can use to indicate which fields they have already investigated. This in turn lowers monitor workload by helping them avoid duplicate efforts.
