Form Logic in Medrio

Solution Sheet

We deliver software that requires minimal logistical oversight, allowing users to focus on the science at the core of their trials rather than technical or administrative headaches. Our work to fulfill that mission extends to the form logic in our software, which is exceptionally easy to use, ensures accurate data entry, and offers key flexibility. Users can build simple edit checks to complex custom queries and test them quickly through an intuitive user interface. Range checks improve data accuracy with “hard” and “soft” warnings when values are out of range; queries can ensure that measurements are taken within allotted time windows, and notifications improve patient safety with real-time alerts when adverse events are likely.


You can nest, combine, and use conditional logic to build queries – and you can do it all in-house, without spending time coordinating with programmers.

Monitors can be confident of data accuracy because edit checks can mitigate common data entry mistakes like transposition, the order of magnitude errors, or values incompatible with life.

  • Data accuracy is enhanced by alerting the person entering the data of unexpected values.
  • Hard warnings prohibit the entry of out-of-range data.
  • Soft warnings prompt review of out-of-range data.

Email Alerts to Stay Informed

Email alerts allow monitors to cut through the noise and surface abnormal results, identify serious adverse events (SAE), and quickly take action based on patterns in geography or demographics.

  • Track serious adverse events in real-time and take action quickly.
  • Identify participants with values dangerously out of range and take action before an SAE takes place.
  • Quickly access relevant participant data through the Medrio EDC platform.

Time-Based Queries to Offer Participants Flexibility

Time-based queries ensure measurements happen at regular intervals while allowing participants flexibility around their busy lives.

  • Use absolute times (every three hours after 9 am) or relative times (six hours after administration of therapy).
  • Flexible time windows balance the need for regular measurements and busy trial participant schedules (e.g. require office visit every 14 days, plus or minus 2 days).
  • If a value is entered outside of the allotted window, an explanation must be associated for monitor review.

Custom queries are among the most time-consuming tasks when building forms. At Medrio, we’ve worked to empower our customers to complete this process with speed and efficiency. In a recent study, a customer created 28 unique forms, 4 visits, and over 200 edit checks – typically a weeks-long process – in three days. With speed and peace of mind, researchers can get back to the science of their trials.

Don't Just Take Our Word For It

“Medrio has superior skip logic, form rules, and custom edit check management to enhance usability. From my perspective, the software allows for rapid development and efficient handling of mid-development changes.” – Christopher Herlong, Managing Member, Study Builders LLC
