Paper based clinical trials

Capturing high volumes of patient data from case report forms, patient surveys, and questionnaires during paper based clinical trials is a time-consuming and labour-intensive task.

eClinical is a hybrid data capture system that combines traditional paper-based data collection (PBDC) with electronic data capture to enable you to process patient data efficiently without compromising accuracy, reliability, or audibility.

For paper-based surveys, eClinical reads paper case report forms via a high-volume document scanner and/or fax server to extract data, record marked diagrams, spot mistakes and verify data before automatically exporting the results into your existing databases.

    How it works

    As new treatment and product development can take many years and cost millions, you cannot underestimate the fundamental role your data capture system plays in determining the outcome of clinical research.

    However big or small the trial, it is prone to human error. As many involve a large number of trial subjects and investigator sites, you have to be able to rely on your data management processes to ensure that the data collected is accurate and meets the trial protocol and SOPs. The simplicity of eClinical is such that any member of your clinical trials team with basic IT literacy skills can take responsibility for designing form templates, scanning and verification as well as system administration.

    Walkthrough the steps involved to get a better grasp of what it can do for you.

    Design

    Build attractive and functional paper questionnaires, surveys, and case report forms (CRFs) in a user-friendly CRF designer to meet trial protocol and standard operating procedures (SOP).

    The form templates will include cornerstones, barcodes, brightness bars and ID blocks to improve the processing of the scanned form with higher capture rates and reduced exception handling.

    Merge & print

    Merge existing datasets onto the template to print forms pre-filled and barcoded, ready for distribution.

    Capture

    Once the forms have been created, printed, and filled in, they need to be converted from paper to an electronic image.

    This is achieved by scanning paper forms on-site or centrally using high-speed document scanners, rather than manually transcribing data.

    Classify

    Once the images are captured, the system will identify the form based on identification blocks, bar codes, or the layout of the page.

    At this stage, the image files undergo image conversion and pre-processing including confirming barcode readability, checking page size and orientation, converting colour images to black and white for best recognition results, and removing image defects e.g., noise and stray marks.

    Extract

    After identifying the template, handprint (ICR), machine print (OCR) and checkbox (OMR) recognition technology extracts and interprets field data from a scanned document. This will include constrained print, tick boxes, variable scales, comments, tick boxes and signatures.

    The system checks rules - including alpha, numeric, dictionaries, date ranges, database lookups and mandatory fields - with exceptions queued for human review.

    The entire process takes seconds - with thousands of forms processed every day.

    Verify

    If human verification is required, scanned images of any field or form needing review are displayed in a high-speed interface for an operator to confirm or correct the data.

    Only invalid data and unrecognisable handwriting is shown to an operator to minimise keystrokes.

    Export

    Export verified data to the Trial Master File (TMF), clinical trial management software (CTMS), or common format (e.g., Excel, CSV, XML or SPSS).

    If the data needs exporting to an in-house patient database, our team has years of experience developing integration components, making it easy for you to access and update information.

    Archive

    Archive scanned images and verified data for instant retrieval later to support regulatory compliance without the need to keep vast amounts of paper originals.

      Teleform/ePC have been the lynchpin of data collection in our home diagnostic clinical trials for many years. As a small team, the software has given us cost-effective and flexible control to manage a diverse range of paper-based trials using a fully-featured form designer with support for downstream verification workflows all the way to export, while ePC have been instrumental in managing and maintaining the service availability with a high standard of professionalism and technical capability

      The data capture is much faster and more accurate. More often than not, forms go through without the need to review them. Any issues are usually related to the design of the form or participants not understanding the question or answering it in a way that was not intended. Many users have said the verification process is not only more accurate, it is less of a chore; they actually enjoy verifying now

      Prior to the launch of the study, our requirements changed frequently and deadlines were very tight. ePC have been very supportive in dealing with these design changes. This is not a typical project but ePC have risen to the challenge and I am happy with the progress achieved so far
