From safety signals to sustained improvement

Autonomous investigations

Agents investigate every safety event end to end, testing causes across all of your data sources. Voice agents interview the people involved to gather additional context outside of the medical record.

Voice interview Opioid-related adverse event
Saved to investigation
Annulum

We are looking at the four opioid-related adverse events on your unit since February. Before we take them one at a time, what was different in the weeks before they started?

Charge nurse

We went to float staff overnight at the start of February. And we stopped doing the bedside huddle around the same time, so handoff became a note in the chart instead of a conversation.

Reviewing staffing changes and linked incident reports
Annulum

Three of the four came after that change. When the note replaced the huddle, what usually got left out?

Charge nurse

Usually why we changed a dose. That was something you said out loud at the bedside, and nobody wrote it down, because it never felt like part of the note.

Pattern detection

Our AI connects safety events across your health system to uncover recurring patterns and shared risks.

System-wide risk detection

Once a cause is identified, Annulum scans across your health system for similar risks, helping teams act before harm occurs.

Intervention design

Annulum designs targeted interventions and measures informed by investigation findings, research, and your system’s prior improvement work.

Intervention

Authorize the fourteen-day 6 West feed-hold insulin checkpoint test

Pacific Vista Medical Center · 6 West Medicine 14 days Nisha Patel, MD Moderate effort

Run the checkpoint on 6 West Medicine for fourteen days. A feed hold with active scheduled basal insulin requires an explicit dose-hold or paired dextrose decision and a glucose recheck four hours later.

Four of the eight cluster events occurred on 6 West Medicine, and the accepted findings show the same feed-interruption and active-insulin sequence across the cluster.

Monitoring and sustainment

Agents track intervention results, investigate slipping performance and unintended effects, and propose follow-up actions.

Agents that learn

Every investigation, intervention, and piece of safety team feedback gives Annulum’s agents more context for the next investigation. Your data is never used to train underlying models.

Memory saved After a unit transfer, check when precautions were set up, even when the fall-risk score is correct.

Another fall after transfer. What should we check first?

Check the time from arrival to precaution setup. In the earlier investigation, scores were accurate but setup took a median of six hours. 1

The falls project introduced a two-hour checklist. Check whether it was completed on the receiving unit. 2

Every finding, supported
Every decision, recorded

Trace findings to their source. Review the evidence and approve consequential actions, with a record of who decided what and why.

The final call stays yours

The agent pauses at important checkpoints, with decisions routed to expert reviewers (patient safety officers, pharmacists, informaticians, etc.). Your team approves or edits, then the agent keeps working.
