Controlled substance occurrence issues in First Due alert supervisors and field personnel when a medication count discrepancy is detected during routine counting procedures. This visual notification system ensures immediate awareness of count failures, maintains regulatory compliance with DEA requirements, and creates an auditable trail of all controlled substance discrepancies. Understanding how to identify, interpret, and resolve occurrence issues is critical for maintaining accurate medication inventory and meeting federal controlled substance tracking standards.
An Occurrence Issue is automatically generated by First Due when a controlled substance count reveals fewer medications than were documented in the previous count. For example, if a med kit was last counted with 3 vials of Fentanyl but the current count shows only 2 vials, the system creates an occurrence to flag this discrepancy. This automated detection system serves multiple purposes: it alerts supervisors to potential compliance issues, creates documentation for DEA audits, maintains chain of custody integrity, and prompts field personnel to document the reason for missing controlled substances.
Occurrences can result from several scenarios including medications used on patients but not documented, controlled substances transferred to another kit without proper logging, medications removed due to damage or expiration, or simple counting errors during the initial count. The system differentiates between agencies tracking individual serial numbers (which can identify the exact missing medication) and those tracking only lot numbers (which shows the quantity missing from a specific lot).
All occurrence issues are documented in the Medication Log and appear in generated PDF log books, ensuring complete compliance with DEA record-keeping requirements and providing comprehensive audit trails for regulatory reviews.
To view, manage, and resolve controlled substance occurrence issues, users must have the following First Due permissions enabled:
Viewing Occurrence Issues:
Resolving Occurrence Issues:
Field personnel typically require all of these permissions to perform daily medication management tasks and resolve discrepancies as they occur. Supervisors and medication coordinators should have access to the Medication Dashboard and Medication Log to monitor occurrences and generate compliance reports.
When you navigate to the Med Kits section after completing a count with a controlled substance discrepancy, the occurrence issue appears with distinct visual indicators:
Visual Appearance:
What This Means: The occurrence issue indicates that during the most recent count, the system detected fewer controlled substances than were documented in the previous count. The medication remains flagged with this visual indicator until corrective action is taken and a new count verifies the accurate inventory.

Occurrence Creation Process:

Supervisor Notification:
Supervisors are notified of controlled substance occurrence issues through multiple channels:
The supervisor can click the eyeball icon in the Med Log to view detailed information about the occurrence, including who performed the count, when it occurred, which specific medication is affected, and any subsequent corrective actions taken.
Occurrence issues can be resolved through three primary methods depending on what actually happened to the missing controlled substance. Best practice is to use the Multi-Action workflow on the desktop version of First Due to document the corrective action and perform a count simultaneously.
Resolution Method 1: Document Usage (When Medication Was Used But Not Logged)
Use this method when the controlled substance was administered to a patient but the usage was not properly documented in the system.

After completing this workflow, the occurrence issue will be cleared from the system because the usage has been documented and a new accurate count has been performed.
Resolution Method 2: Document Transfer (When Medication Was Moved to Another Kit)
Use this method when the controlled substance was transferred to another med kit or medication supply but the transfer was not properly documented.
The occurrence will be cleared once the transfer is documented and a new count verifies the accurate remaining inventory in the source kit.
Resolution Method 3: Document Removal (When Medication Is Actually Missing or Damaged)
Use this method when the controlled substance is truly missing, damaged, expired, or otherwise needs to be removed from inventory with documentation for DEA compliance.
After documenting the removal with proper reason and signatures, the occurrence is cleared and the removal is permanently recorded in the Med Log for compliance purposes.
Resolution Method 4: Perform Re-Count (When Original Count Was Entered Incorrectly)
If the occurrence was created due to a simple data entry error during the original count:
If the re-count shows the correct number of medications (matching the expected count), the occurrence will be automatically cleared because the system recognizes the counts now match.
The Multi-Action workflow is the recommended method for resolving occurrence issues because it allows you to:
Multi-Action is only available on the desktop version of First Due, so supervisors and medication coordinators should use desktop computers when resolving complex occurrence issues.

Supervisors and medication coordinators need to audit occurrence issues for compliance tracking, DEA reporting, and investigation purposes. First Due provides a comprehensive audit workflow through the Medication Log.

Communication:
Q: I completed a usage and count to clear an occurrence, but the red X is still showing. What should I do?
A: Ensure you completed all steps including the final count and signatures. The occurrence only clears once a new count is successfully completed and signed. If the issue persists after completing all steps, check that the usage or removal you documented was for the correct serial number or lot number. Contact your medication coordinator if the occurrence remains after verification.
Q: What happens if I can't explain why a controlled substance is missing?
A: Document a removal with the reason "Missing" and provide as much detail as possible about when you discovered the discrepancy. Notify your supervisor immediately. Your agency may have additional investigation protocols for unexplained controlled substance losses. All occurrences are tracked in the system for compliance and audit purposes.
Q: Can I resolve an occurrence from the mobile app?
A: Yes, you can resolve occurrences from the mobile app by documenting usage, transfer, or removal followed by a count. However, the Multi-Action workflow (which is more efficient) is only available on the desktop version of First Due. For complex situations, supervisors recommend using a desktop computer.
Q: How long do occurrence issues stay in the system?
A: Occurrence issues remain visible with the red X indicator until they are resolved through proper documentation (usage, transfer, removal, or corrective count). Once resolved, the occurrence documentation remains permanently in the Med Log and PDF log books for compliance purposes, but the red X visual indicator is removed.
Q: What if I create an occurrence by mistake during counting?
A: Simply perform another count immediately. If you accidentally marked a medication as missing when it was actually present, the next count showing the correct number will clear the occurrence. However, the occurrence will still appear in the Med Log as part of the audit trail.
Q: Do occurrences affect my ability to perform custody exchanges?
A: No, occurrence issues do not prevent custody exchanges. However, best practice is to resolve occurrences before performing a custody exchange so the receiving personnel start their shift with accurate inventory. Both parties should be aware of any unresolved occurrences during the exchange process.
Q: What's the difference between an occurrence and a missing medication?
A: An occurrence is the system notification that a count discrepancy has been detected. A missing medication is one of several possible reasons for an occurrence. Other reasons include unreported usage, undocumented transfers, or counting errors. The occurrence is the alert; the investigation determines the actual reason.
Q: Can supervisors see who created an occurrence?
A: Yes, supervisors can view complete details about occurrences including who performed the count that created the occurrence, the date and time, which specific medication is affected, and all subsequent actions taken to resolve it. This information is available in the Med Log detail view.
Q: How do occurrence issues appear in PDF log books for audits?
A: Occurrence issues are highlighted in PDF log books with the same red visual indicators seen in the system interface. The PDF shows the original count that created the occurrence, the "Count-failed" status, and all corrective actions taken including usage documentation, transfers, or removals. This provides a complete audit trail for DEA inspections.
Q: What if multiple occurrences exist on the same medication?
A: Each occurrence must be resolved individually. If you have multiple occurrences for the same medication, work backwards from the most recent to understand what happened. You may need to document multiple usage events, transfers, or removals. Contact your supervisor for guidance on resolving complex occurrence patterns.
Q: Are witnesses required for all occurrence resolutions?
A: Witness signatures are typically required for controlled substance removal actions. Usage and transfer actions may require witness signatures depending on your agency's policies. Check with your medication coordinator about specific witness requirements for your department.
Q: Can I delete or hide an occurrence?
A: No, occurrences cannot be deleted from the system. They are part of the permanent controlled substance audit trail required for DEA compliance. Once an occurrence is created, it can only be resolved through proper documentation, not removed from the record.
All controlled substance occurrence issues create permanent entries in First Due's audit trail system that cannot be deleted or modified. This comprehensive documentation meets DEA requirements for controlled substance tracking and provides complete chain of custody records. When generating detailed Med Logs for regulatory inspections, occurrence issues appear with:
