eCRF Database

The KCTU has hosted a commercial data entry system (Elsevier MACRO) since 2005. The system is compliant with FDA 21 CFR part 11 and Good Clinical Practice (GCP).

It is an appropriate system to use for medicinal trials falling under the Medicines for Human Use (Clinical Trials) Regulations 2004 and its subsequent amendments, and has also been used for other complex intervention trials. The web based system can be accessed 24 hours a day.

Roles can be assigned to users, giving the ability to enter data relating to participants or to view data and raise discrepancies, but not amend data. Roles can also be tailored to be blind to treatment allocation where appropriate, with a secondary database being programmed to collect information about therapy sessions or surgical interventions, for example.

The system can be programmed to perform validation checks, such as range checks to prevent data entry errors. Missing data codes are routinely programmed into all fields, for ease of analysis. The system can also be programmed to flag up when a missing data code is entered, to aid monitoring. The system can also be programmed to include e-signatures, where this is required.  A standard feature of InferMed MACRO data entry system is the built in audit trail on all data fields, the automatic saving of data as you leave a form, and the ability to maintain a record of ‘source data verification’ checks. The system also has formal database lock functionality. 

Package Costs

The cost calculation of programming and hosting a data entry system for a study depends on the number of unique data variables to be programmed, the number of study sites, the number of users and variety of access required, the duration of time the system needs to be ‘live’ and the expected number of data extract requests required for data cleaning, data monitoring committee and trial steering committee reports during the study.
