The Hidden Costs of Bad Claimant Data in Mass Tort Litigation
In mass tort litigation, collecting claimant data is only the beginning. The greater challenge is understanding what information you actually have.
A single claimant file may contain hundreds or thousands of pages, with critical information missing, duplicated, inconsistent, or buried across different types of records. Identifying those issues manually across a large inventory can require significant time and resources.
When bad data goes undetected, it can create deficiencies, complicate case development, weaken inventory assessments, and increase administrative work throughout the litigation.
Understanding Claimant Data at Scale
At scale, claimant management requires more than determining whether a file exists.
Legal teams need to understand what each claimant's file contains, whether required information is present, what additional records may need to be ordered or reviewed, and whether information across documents is consistent.
A manual review may require someone to work through hundreds or thousands of pages, identify relevant information, compare it across sources, and determine what is still missing. Multiply that process across hundreds or thousands of claimants, and understanding the inventory becomes a significant operational burden.
Where Bad Claimant Data Creates Problems
Deficiencies Can Be Difficult to Identify
A claimant may have submitted a Plaintiff Fact Sheet (PFS), medical records, questionnaires, and supporting documents without providing everything needed for the current phase of litigation.
Identifying those deficiencies requires understanding what is present, what is missing, and what the available documents actually establish.
Inconsistencies Can Be Buried Across Documents
Claimant files may contain overlapping information from different sources. Dates, diagnoses, procedures, providers, or other details may not always align.
Identifying those discrepancies manually can require teams to compare information across hundreds or thousands of pages.
Inventory Assessments Depend on the Underlying Data
Plaintiff firms and MDL leadership need visibility into more than individual claimant files. They also need to understand the inventory as a whole.
Incomplete or poorly organized data can make it difficult to determine which claimants have sufficient documentation, where common deficiencies exist, what additional records may be needed, and how the inventory looks as a whole.
Reliable inventory-level reporting starts with reliable claimant-level data.
Different Claimants Rarely Submit Identical Records
One of the challenges of mass tort administration is that claimant files are rarely uniform. Relevant information may appear in completely different documents from one claimant to the next.
AIM can review more than 50 document types and ask the same targeted question across different types of records. This allows firms to evaluate the same data point across an inventory even when the underlying source documents differ.
AIM also uses document hierarchy to help prioritize the appropriate source when similar information appears in multiple records.
The result is a more consistent way to evaluate claimant data without requiring every claimant to submit information in exactly the same format.
The Questions Change as the Litigation Changes
The information a firm needs can change throughout the litigation. Early in a matter, teams may need to confirm whether specific records or proof are present. Later, the focus may shift to diagnoses, treatments, dates, exposure evidence, deficiencies, or other requirements.
AIM is tailored to the litigation. Firms can ask different questions of their data at different phases of a matter and customize those questions from tort to tort.
Rather than producing a fixed summary, AIM helps teams interrogate claimant data based on the questions that matter at that stage of the litigation.
Document Hierarchy Matters
Finding information is only part of the review. Teams also need to understand where that information came from.
When similar information appears in multiple documents, the sources may not carry the same evidentiary value. AIM uses document hierarchy to prioritize more authoritative records when similar information appears across multiple documents, while connecting findings back to the source.
AIM's managed review model also incorporates clinical validation, combining purpose-built AI with experienced human review to help verify critical details and maintain a transparent review trail.
This gives legal teams greater context for evaluating the information surfaced from a claimant's file rather than relying on an AI-generated summary without supporting documentation.
Better Claimant Data Supports the Work That Comes Next
Poor claimant data does not remain isolated to the document-review stage.
Incomplete information can create deficiencies in Plaintiff Fact Sheets and other submissions, while disorganized records and unidentified discrepancies can require additional review and follow-up.
Data quality can also affect downstream claims administration and settlement administration workflows, making accurate, organized claimant information important throughout the lifecycle of a matter.
Identifying gaps and inconsistencies earlier can give firms greater visibility into their inventories and reduce the manual work required to determine what each claimant file contains and what still needs attention.
Turn Claimant Records Into Usable Case Intelligence
Managing large claimant inventories does not simply require more data. It requires a reliable way to understand that data.
AIM combines purpose-built AI with experienced clinical review to identify relevant information, surface inconsistencies, structure findings, and connect critical details back to their source.
Because the review can be tailored to the litigation's specific questions and requirements, firms can apply a consistent framework even when claimant records vary significantly.
For plaintiff firms, MDL leadership, and legal operations teams, that means greater visibility into claimant files without relying solely on time-intensive manual review.
