Clinical trials involve various steps, and one of the essential ones is data collection. For a clinical trial study to be successful, you must have accurate and well-organised data. However, this process may come with numerous challenges. For instance, inconsistency may result in errors. And if the data you collect isn't correct, you may be unable to analyse it accurately and won't answer the research question. This may make your study futile. 

Fortunately, an annotated Case Report Form (CRF) addresses these challenges and enhances the efficiency of your data. They aim to offer superior knowledge to anyone reviewing your data in databases through comments or notes. That said, here's what you need to know about annotated CRFs:     

Meaning Of Annotated CRF

An annotated CRF is an empty CRF with labels or annotations that match every data point in the form with its related database name. An annotated CRF maps collected data for its storage collection in the database.   

Regulatory Requirements For Annotated CRFs

Before submitting your  annotated CRFs, you must confirm that they meet the Food and Drug Administration (FDA) requirements. Some of the regulations include the following:

  • You should submit it as a PDF (Portable Document Format) with the file name 'acrf.pdf.'
  • Ensure you add the variable name and the coding for every CRF document.
  • You must submit them at the same time as your protocol.
  • If you record data on the CRF and don't submit, annotate it with the text 'Not submitted' and include an explanation of why you didn't submit the data.
  • You should add treatment assignment forms, if applicable, and map every variable on the CRF to matching variables in the database.

In addition to the above requirements, here are some technical regulations you must apply when formatting annotations of CRFs.

  • Your texts must be black, but you may have blue for hyperlinks.
  • Don't secure your documents with a password.
  • Use font sizes ranging from 9 to 12 points. It's advisable to use Times New Roman 12-point font for narrative texts. Additionally, you can use 9 or 10 points for tables and 10 for footnotes. 
  • Prepare the print area of pages to fit an 8.5 by 11 inches sheet of paper.
  • Use PDF versions 1.4 through 1.7, PDF/A-1 and PDF/A-2.

These are just some of the requirements. For more information, consider visiting the FDA's website.    

Importance Of Annotated CRF In Clinical Trial Data Collection

Adopting annotated CRF to your clinical trial data collection has numerous benefits. Some of the advantages include the following:

  1. It Saves You Time

Collecting your clinical trial data collection manually may consume a lot of time. You may create a separate file explaining the information in your Study Data Tabulation Model (SDTM). This can indeed take a great deal of time. Additionally, the parties involved may find it hard to go through your data and then explain and try to match the information in the two documents. 

The good thing about annotated CRFs is that you can effortlessly illustrate your data by highlighting and adding a description. This allows your team members to view your data in one document, which saves a lot of time.

  1. It Enhances Data Accuracy And Speed

Typically, traditional data collection methods may take several years to be approved. This is because these methods are prone to errors, and you may have to conduct several trials before obtaining your desired results. However, automating your process with annotated CRF improves data accuracy and, thus, the speed of discovery.

  1. It Supports Data Consistency

As outlined above, an annotated CRF enables you to indicate where data is stored in the database. If you set your tool appropriately from the beginning of the process, the remaining dataset follows through to the last part of your analysis.

  1. It Identifies Fundamental Information

When collecting data for your clinical trial study, you may have a lot of information, each with different importance. An annotated CRF lets you highlight important details and describe why your team members should emphasise the highlighted data.  

  1. It Enhances Collaboration

Clinical trial studies involve several team members and can go through various stages before approval. Annotated CRFs enable each of your members and management team to edit or add comments to the document. This is essential as you can work together as a team from any location, thus saving a lot of time and effort.          

The Cost Of Annotating A CRF

The cost of annotating a CRF depends on the number of your CRF pages and the complexity of your study. In essence, a clinical study form can contain one or more pages. The more pages you have, the longer you may take annotating, and the more it may cost. On the other hand, a complex study may cost more than a simple one. For instance, a trial involving different types of patients may take more time and money compared to a similar test with only one patient. 

Conclusion

Since clinical trials take several years to come up with a valid conclusion, you must take precautions at every step. This ensures you avoid repeating any phase and spend more years and resources. One of the best methods of eliminating errors and enhancing your speed is through annotated CRFs. This tool helps you to save time by matching collected data to where it's stored in the database. Ensure you know everything about it, use it in your clinical trial study, and speed up the development of new medications.
