Read-Only Before Writeback for Radiology Ops

Recommendation and writeback are separate decisions

A demo may show an agent finding a missing prior, a blank reason for exam, a laterality conflict, or an open hold. The next conversation often turns to automated tags, status changes, and moving studies out of Pending. Finding a blocker and changing the system of record require separate decisions. First, determine whether the agent notices the same problems a careful PACS admin would.

During a read-only evaluation, the agent can inspect a case and recommend what should happen next. It cannot write a Reason for Exam, apply a tag, change a status, create a task, or claim that a study has exited Pending. Keeping recommendations separate from source state gives the ops team a practical way to judge their quality before enabling any write path.

What to score during a read-only evaluation

Choose a manageable set of Pending cases your team already understands. Score the agent against the readiness criteria you use today, including the checklist behind what makes a study read-ready. For each case, ask:

1. Did it surface the real blocker? Look for a missing prior, an unusable reason for exam, a laterality or body-part conflict, an open hold, or a mismatch between the order and the performed exam. Note any problem the agent raised that was not there.
2. Did it stay silent when the record was actually ready? False positives burn admin time the same way false negatives burn reader time.
3. Is the proposed next step owned and concrete? "Needs review" with no owner is not remediation. A usable proposal names who acts and what source change would clear the hold.
4. Does unknown stay unknown? Missing, stale, or conflicting evidence should lead to review instead of a fabricated pass.

Name the people doing the scoring. PACS admins own Pending QC because they already manage tags, statuses, and source corrections. Their judgment provides the baseline. Radiologists can report when incomplete studies reach them, but the admins who operate the queue should grade the recommendations.

Study the disagreements

Expect disagreements. The agent will miss some cases, and the exercise may expose readiness criteria that your team has never written down. Record specific failure modes such as an incorrect laterality call, a prior marked present when it was not retrieved, or boilerplate treated as a sufficient reason for exam. A single accuracy percentage hides these details.

The first evaluation does not need an ROI estimate. Ask whether the recommendations would help admins catch problems in cases that stall or reach the reading workflow incomplete. As we discuss in the hidden cost of incomplete studies, finding the gap after interpretation starts creates avoidable rework. A read-only evaluation shows whether the agent could have identified it earlier without changing source state.

When writeback is still gated

A successful read-only evaluation does not justify unsupervised writes. It shows that the findings and proposals may be useful enough for a human to approve a narrow change. A safe write path still requires:

• An authorized person approving the exact target, action, proposed values, and expected read-back for that case.
• A scoped adapter that can perform only the approved mutation, rather than a general credential that lets the agent edit PACS.
• Authoritative read-back after the write, so the system confirms what changed and what required state remained.
• Recheck after remediation: clearing a tag or filling a field does not auto-declare the study read-ready until the affected checks run again.

Evaluate each capability on its own. Classification recommendations, Reason-for-Exam proposals, and status changes need separate read-only evaluations and approval gates. Good performance on laterality conflicts says little about performance on payer-family classification.

How Corena approaches writeback

Corena performs operational QC for studies in a PACS Pending queue. It produces evidence-backed findings and proposed actions for human review. Rollout begins with source writes disabled. Corena reads source state, evaluates readiness, and recommends release or remediation. A write remains unavailable until the specific capability and customer policy allow a human to approve it. Corena does not interpret images, generate clinical reports, or assign the radiologist.

Start with a read-only review of cases your admins already know were blocked or released too soon. Request a demo to apply this evaluation to your queue before discussing writeback.
