Keep one study record

Store the consent version, schedule, contact list, visit instructions, device guide, payment terms, receipts, and your questions together. Add each change with a date and source. Keep study records separate from unrelated personal documents.

Use the protocol or participant identifier the site provides. Avoid putting diagnoses or detailed health information into calendar titles, shared task apps, or unencrypted notes.

Treat diary windows as appointments

Record the opening and closing time, expected duration, reminder method, missed-entry rule, time-zone rule, and support contact. Ask whether an entry must reflect the moment, the full day, or a recall period. Ask how corrections work.

Enter what happened. Do not guess, copy prior answers, change an answer to appear compliant, or backfill without instruction. Report a missed entry and the reason through the study’s approved channel.

Track device state and skin or usability problems

Record charging, syncing, placement, calibration, cleaning, updates, travel, replacement, and return rules. Report lost connectivity, incorrect time, damage, discomfort, rash, pressure, sleep disruption, or another problem.

Ask whether the device provides clinical monitoring. A research device may collect data without providing real-time medical oversight. Follow the consent and emergency instructions; do not assume the app alerts staff.

Reassess when the study changes

Ask for written clarification when visits, procedures, restrictions, risks, payment, vendors, or follow-up change. Material changes may require revised consent. Read the new information and compare it with your original decision.

Update your burden calculation. A new weekly task, longer visit, or transportation rule can change feasibility even when the intervention stays the same.

Report symptoms through the study safety path

Use the study’s instructions for symptoms, adverse events, medication changes, emergency care, pregnancy, hospitalization, or new diagnoses. For an emergency, seek emergency help and identify your study involvement when relevant.

Severity describes intensity. Seriousness is a regulatory outcome category that includes death, a life-threatening event, hospitalization or prolonged hospitalization, persistent or significant disability, a congenital anomaly, or another important medical event that may require intervention. FDA defines serious adverse events (opens in a new tab). Report the event; let qualified staff classify it.

Reconcile visits and payment as they occur

After each activity, record the date, completed item, expected amount, reimbursable expense, receipt, payment method, and expected issue date. Ask about discrepancies while records are recent.

Keep payment questions separate from safety reporting. Do not delay a symptom report because you fear losing compensation. Ask the rights contact if payment pressure appears to interfere with voluntary choice.
