Sensitive data (SD) does not belong in a paper notebook! While the ERN is approved for storage of sensitive data (SD)*, there are other resources to use, depending on your research. For research data which includes protected health information (PHI) or personally identifiable information (PII):
The Clinical Trial Management System (CTMS) should hold SD related to clinical trials
MiChart should hold SD related to clinical care for research participants
OpenClinica should hold SD related to studies or trials. Electronic data capture of study data should also be in OpenClinica when more sophisticated validation checks are needed
REDCap should hold SD where electronic data capture is needed
The ERN can hold SD for which the above conditions don't apply*
ERN is not yet ITAR-compliant
