Reported by NEW HAMPSHIRE AG filing
Littleton Regional Hospital notified the NH Attorney General on April 13, 2009, of a security breach involving a patient's computerized personal information. A former employee accessed the data on three dates in late 2008/early 2009 for non-business purposes. The hospital detected the breach via a patient complaint on March 25, 2009, and notified the patient on March 27, 2009.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
