To address this, we now provide new reporting services, enabling the physicians to record (signatures and dates) that they have reviewed the abnormal test results.

What is ALCOA?

The five fundamental requirements for source documents, whether paper or electronic, defined by FDA are shown below. These requirements stand for the acronym "ALCOA".

  • Attributable: It can clearly be shown to whom documents attribute to, or who is responsible for them.
  • Legible: Documents are readable and easily understood.
  • Contemporaneous: Activities are recorded at the time they occur
  • Original: Documents are the original versions. That is, they are not photocopies* or transcriptions.
  • Accuracy: Documents are error-free.
  • *This requirement excludes certified copies, that is, photocopies that are assured to be identical to the originals.

I can obtain the printout from the study coordinator in a timely manner. I do not personally log into CRAD, but the hard-copy information is easy to understand and helpful.

Study Coordinator
I use CRAD several times a day because I can review the study progress and schedule for each subject. I can check the subject’s upcoming test schedules in CRAD. This feature enables the accurate progression, which is helpful. In addition, when we share the information with physicians, test results can be downloaded in Excel. We can add essential information and pull the information. The system is easy to use.

The up-to-date test data can be reviewed on the top screen. This is convenient when we need to know the results quickly. In addition, with alert values set for multiple conditions, you become immediately aware of abnormal test results and can perform safe medical treatment, which is very helpful.

CRA's project manager
I always check CRAD to view the test results and subject progress status. CRAD allows sharing the comprehensive information with CRAs who often go on business trips or work out of the office.

Personnel responsible for international clinical trials
CRAD can be provided in English, so the test results from sites in Japan can be reviewed in English. Even international clinical trials can be managed without stress.
