Paper Forms in Health Care Systems and Controlled Clinical Trials |
| |
At present, over 75% of all data acquired in controlled clinical trials, EMR systems, and related clinical environments is entered onto paper forms, starting a paper trail that imposes fundamental workflow inefficiencies and enormous costs. Replacing paper as a data capture medium is the "Holy Grail" of both the pharmaceutical services IT as well as the EMR industries. However, replacing paper has proven to be very difficult. Off-the-shelf Tablet PCs, Slate PCs, PDAs, and other handheld devices, designed for horizontal consumer markets, have proven useful for accessing information and simplified data entry, but do not approach the threshold for true utility in these application areas and are not an acceptable replacement for full-size paper forms. |

Problem: The Burden of Paper in Controlled Clinical Trials |
| |
Controlled clinical trials require the collection of vast amounts of information on each participant. Most information is initially recorded on paper, defining a "source document." Currently, all source documents such as screening evaluations, medical examinations, psychiatric rating scales (e.g. PANSS, CIBIC), concomitant medications, etc., consist of paper forms. Subsequently, every data point must be manually transferred to a second paper form, defining a Case Report Form (CRF). CRFs are summary documents created from source documents by clinical study coordinators to report to study sponsors and satisfy regulatory agency requirements. Manually creating a CRF (i.e. transcribing source documents manually) can take as much, if not more time, than the originating activity itself. |
| |
Solution: Point-of-Care (POC) Data Capture |
| |
In controlled clinical trials, direct electronic data capture at the point-of-care (POC) eliminates the need for manually-created CRFs. Acquiring a clinician’s or researcher’s entries at POC not only achieves immediate registration and storage in the digital domain, but also enables a range of post-acquisitions operations such as structured query access, network-based data transmission, centralized archiving, and cross-enterprise data sharing. Further, computerized post-acquisition processing of an electronically-based source document greatly increases the efficiency of error identification and automatically creates a secure audit trail. |

Electronic Data Capture in Clinical Trials: the Halfway Point to True Efficiency
|
|
Electronic Data Capture (EDC) has enabled more rapid collection and review of clinical trial
data. However, contemporary EDC has multiple limitations, the most important of which is the
reliance on paper forms for primary data capture. Once data is captured onto paper forms, each
entry (e.g. digital value) is manually typed onto a web form. Contemporary EDC can be labeled
“paper-to-electronic-CRF” as the electronic capture process is, in reality, one large, critical step removed.
Contemporary EDC is not to be confused with true POC data capture.

Direct EDC vs. Paper-to-CRF
|
|
Accordingly, direct EDC (dEDC™) offers the following fundamental advantages over current
"paper-to-electronic-CRF" solutions ():
|
- Eliminates paper source documents
- Eliminates manual transcription and double-data entry
- Eliminates source verification processes
- Improves quality/accuracy of data collected
- Reduces number of queries by validating data upon entry
- Enables immediate evaluation/audit
- Reduces need for and time required to perform on-site monitoring
- Reduces time from Last Patient/Last Visit (LPLV) to database lock (DBL)
|
In the figures below, the differentiation between contemporary EDC and direct EDC is presented. |

Commercially Available Slate PCs are not a Viable Solution |
| |
| The concept of integrating personal computer electronics in a slate-like form factor device was conceptualized in the mid-1990's and numerous devices were manufactured, most featured a touch screen or digitizer pen capable of capturing handwriting. Currently available slate PCs are essentially reconfigured notebook PCs and are poorly suited as a platform for wide-ranging translation of paper forms into “active” electronic forms for application in clinical trials or hospital environments. Slate PCs designed for large, horizontal consumer markets are: |
| |
- Too heavy (3-6 lbs)
- Limited by screen size
- Too hot to hold comfortably
- Limited by relatively short battery life
|
| |
|
A comparison of representative sPC devices by weight, display size, thickness, battery life, and power consumption is outlined Here. |
