There is no need to inform the IRB. However:
- If your study is a greater-than-minimal risk study that involves some type of patient care, you must ensure your suspension does not increase any risk to those study subjects.
- If possible, make sure you contact any study subject who will be affected by this suspension (i.e., a study visit will be canceled, etc.)
- You should make a note in your study records of this temporary suspension along with the justification and any actions taken in case you are ever audited.
