Why paper-based chain of custody fails healthcare logistics

1 in 3

paper custody logs contain errors or gaps

Illegible handwriting, missing timestamps, skipped signatures.

72%

of custody disputes involve lost or incomplete records

No paper trail means no liability protection.

Hours

spent reconstructing custody history during audits

Time hunting binders that should already be in a database.

How Digital Chain of Custody Works

Every custody event is logged the moment it happens, tied to the delivery record, and locked against modification.

01

Pickup Recorded

When a courier picks up a specimen, a custody event is created — capturing courier identity, time, location, and specimen details. The clock starts here.

02

Every Transfer Logged

Each handoff between couriers, facilities, or departments creates a new custody event in the chain. No handoff can be skipped — required-custody deliveries enforce logging before status advances.

03

Real-Time Visibility

Dispatchers and managers see the full custody chain for any delivery in real time. Who has it, where was it last transferred, how long ago — all visible from the dashboard.

04

Audit-Ready Export

When a compliance review, dispute, or accreditation audit arrives, export a complete custody log for any delivery — timestamped, immutable, and formatted for review.

Paper Logs vs. Digital Custody

Paper-Based Custody Logs

  • Signatures can be forged, added after the fact, or left blank
  • Lost or damaged logs create unresolvable custody gaps
  • No real-time visibility — you find out about problems after delivery
  • Reconstructing a custody chain during an audit takes hours
  • No enforcement — couriers can skip logging steps
  • Can't prove who handled the specimen at any given moment

Tacit OS Digital Custody

  • Immutable records — logged events cannot be altered or deleted
  • Every handoff captured in real time with device identity
  • Live dashboard shows current custody holder for any delivery
  • One-click export of complete custody history for any specimen
  • Required-custody flag enforces logging before status can advance
  • Full who/when/where for every custody event, forever

Built for Regulatory-Grade Compliance

Every feature is designed for the audit requirements of CLIA, CAP, Joint Commission, and state health department standards.

Immutable Audit Trail

Once a custody event is recorded, it cannot be edited or deleted. Every entry includes a server-side timestamp and the authenticated user's identity.

Required-Custody Enforcement

Flag deliveries that must have a documented custody chain. The system prevents status advancement until each handoff is logged.

Precise Timestamps

All custody events are stamped with server-side UTC time — not device clock time — eliminating the ability to backdate or manipulate records.

Real-Time Dashboard View

See which courier currently has custody of any active delivery, when the last handoff occurred, and how many custody events have happened.

Compliance Export

Generate a complete custody report for any delivery in seconds — suitable for presenting to accreditation bodies, legal proceedings, or client audits.

Linked to Delivery Record

Every custody event is permanently linked to its delivery, so there's no way to orphan a custody log from its specimen record.

Who Needs Digital Chain of Custody?

Clinical Laboratories

Maintain specimen integrity from collection to receipt. Every handoff between phlebotomist, courier, and lab intake is logged and verifiable.

Blood Banks

Blood products require unbroken documentation from draw to transfusion. Digital custody ensures no gap in the chain for regulatory compliance.

Pathology & Oncology

Tissue and biopsy specimens demand rigorous custody tracking. Audit-ready records protect facilities and patients when questions arise.
