Running a Mass Tort Inventory: Fact Sheets, Records at Volume, and the Clocks That Dismiss Claims

The Judicial Panel on Multidistrict Litigation publishes a statistics report on the first business day of every month. The one dated August 3, 2026 is worth reading closely if you run a plaintiff firm, because it contains a fact about the shape of this work that most staffing conversations ignore.

There were 162 active MDL dockets holding 205,540 pending actions across 51 transferee districts and 140 transferee judges. Of those 162 dockets, 21 carried 1,000 or more pending actions each. Those 21 dockets held 94.19 percent of every pending MDL action in the country. At the other end, 38 dockets had ten or fewer actions and together accounted for 0.07 percent of the total. One proceeding alone, the Johnson & Johnson talcum powder litigation before Judge Michael A. Shipp in the District of New Jersey, carried 68,914 pending actions, which is roughly a third of all pending MDL claims sitting on one docket. You can pull the current numbers yourself from the Panel's pending MDL reports page.

The operational reading of that distribution is simple. Almost all MDL activity in the United States is volume activity, and the firms participating in it are not managing cases. They are managing inventory. That is a different business with a different failure mode, and the thing that most often breaks is not the law. It is the paperwork clock.

This guide maps the queues that decide whether a mass tort inventory holds its value, points at the primary sources that set the deadlines, and marks where the operational work has to stop and an attorney has to take over. It is written for firm owners and legal operations leads deciding what to staff first. It is not legal advice, and nothing in it substitutes for the case management orders actually governing your proceedings.

Why a personal injury back office breaks on its first mass tort inventory

A firm that handles single-event injury cases well has built an operation around attorney attention. Each file has a story, a treating physician, an adjuster, a demand, and a negotiation, and the paralegal supporting it holds most of that in working memory. Throughput is a function of how many files a good person can hold at once, and the answer is usually somewhere between forty and a hundred and twenty depending on complexity.

Mass tort breaks that model in three specific ways.

Claims move through gates together, not individually. In a single-event case, a missed task delays one file. In an MDL, a fact sheet protocol applies to every claimant at once, with one deadline, and the work arrives as a wave rather than a stream. A team sized for steady-state file work is structurally unable to absorb a wave, which is why so many firms discover their staffing gap on a weekend three days before a service deadline.

The unit of reporting is the inventory, not the file. Nobody asks how claimant 2,317 is doing. They ask what the fact sheet compliance rate is, how many deficiencies are open and how old they are, how many claimants still lack product identification, and how many records requests are past thirty days. Those questions cannot be answered out of free-text case notes. They require structured fields, and structured fields require someone whose job is keeping them accurate.

The consequences are categorical. In ordinary discovery, a dispute produces a meet-and-confer and a motion. In a fact sheet process, case management orders commonly provide for dismissal. The Federal Judicial Center's pocket guide for transferee judges makes the point directly: because many case management orders provide for dismissal of cases for incomplete or deficient fact sheets, disputes over fact sheets can carry more severe consequences for plaintiffs than other discovery matters do.

That is the whole argument for staffing mass tort operations deliberately. The work is clerical. The exposure is not.

What changed on December 1, 2025

Until recently, the Federal Rules of Civil Procedure said nothing specific about MDL practice. Everything ran on 28 U.S.C. § 1407, the transferee judge's case management orders, and accumulated practice captured in the Manual for Complex Litigation and the Federal Judicial Center's guides.

That changed with Federal Rule of Civil Procedure 16.1, effective December 1, 2025, the first federal rule written specifically for multidistrict litigation. It is a framework rule rather than a mandate. Rule 16.1(a) says the transferee court should schedule an initial management conference to develop an initial plan for orderly pretrial activity. Rule 16.1(b) directs the parties to meet and submit a report before that conference addressing a defined list of matters: under (b)(2), leadership counsel and its selection, structure, responsibilities and compensation, orders that should be vacated or modified, the schedule for further conferences, management of direct-filed actions, and coordination with related actions in other courts; and under (b)(3), the parties' initial views on consolidated pleadings, discovery, likely pretrial motions, measures to facilitate resolution, referral to a magistrate judge or master, and the principal factual and legal issues. Rule 16.1(c) then contemplates an initial management order.

For an operations lead, the subsection that matters most is Rule 16.1(b)(3)(B): the report must address the parties' initial views on "how and when the parties will exchange information about the factual bases for their claims and defenses."

That single clause is where the fact sheet, profile form, or census process now gets negotiated in most newly centralized proceedings. It also means the timing question that used to be unpredictable is becoming more predictable. If your firm is in a proceeding centralized after December 2025, the shape of your fact sheet obligation is likely to be visible earlier than it once was, which is an operational gift if you are paying attention and a trap if you are not staffed to act on it. Commentators disagree about whether the rule will change outcomes, since it imposes no mandatory obligations on transferee courts, but the reporting requirement itself is now standard.

The fact sheet machine

Plaintiff fact sheets are the operational center of a mass tort practice. The Federal Judicial Center and the JPML published a pocket guide for transferee judges, Plaintiff Fact Sheets in Multidistrict Litigation Proceedings by Margaret S. Williams, Jason A. Cantone, and Emery G. Lee III, which remains the clearest public description of how these processes are built and enforced. The underlying empirical study, Plaintiff Fact Sheets in Multidistrict Litigation: Products Liability Proceedings 2008 to 2018, sits behind it.

A few things from that guide have direct staffing consequences.

Fact sheets are treated as discovery responses. They are party-negotiated, court-approved standardized questionnaires, used during discovery, and their responses are generally treated as answers to interrogatories and requests for production. They are sworn statements completed under penalty of perjury. They are not, however, Lone Pine orders: unlike the order that came out of Lore v. Lone Pine Corp., a fact sheet does not require case-specific expert affidavits on causation. That distinction matters when scoping the work, because it means the content is factual and documentary rather than expert-driven, and therefore assemblable by trained support staff under attorney supervision.

The content is predictable. The guide lists what is typically required of plaintiffs: when and why the plaintiff used a product, device, or service; product identification records including brand and model; the plaintiff's medical history; the injuries sustained; and requests for related documents and a witness list. Fact sheets also commonly ask about background matters such as education, employment, criminal history, social media use, and litigation history, and typically include releases for medical, insurance, and financial information. Because the categories repeat across proceedings, and because approved fact sheets from earlier proceedings are often used as templates in later negotiations, a firm can build a durable internal collection checklist and reuse most of it.

Timing varies more than firms expect. The guide notes that the interval between centralization and a fact sheet order has ranged from forty-five days to several years, averaging about eight months from centralization, with the variation driven largely by how long leadership appointment and content negotiation take. Deadlines within the order vary too. In In re Fluoroquinolone Products Liability Litigation, the court set the fact sheet deadline at three months from the date of the order for cases already in the proceeding, and sixty days for cases joining later. Later-filed and tag-along cases almost always carry their own rolling deadline, which means the fact sheet queue never actually closes while the inventory is growing.

The deficiency process is where claims die. The general pattern is that opposing counsel notifies the noncompliant party of a deficiency, then the party gets a cure period. The guide reports notice periods that in some proceedings ran forty-five days after a fact sheet was overdue and in others considerably less, followed by cure deadlines commonly in the range of two to six weeks. Specific examples cited include a fourteen day cure period in the DuPont C-8 personal injury litigation and a forty-two day cure period for one plaintiff group in the Roundup litigation. Enforcement mechanisms have included motions to dismiss under Rules 41(b) and 37, show cause orders, and call dockets. In the Lipitor II proceeding, the transferee court eventually dismissed some plaintiffs with prejudice for failure to comply.

Read that sequence as an operations problem and the staffing answer writes itself. A deficiency list is a standing queue with a strict age limit, and it needs a named owner, a daily touch, and an aging report the partners actually see. A firm that treats each defendant deficiency notice as a discrete fire drill will eventually lose claims that had merit, for reasons that have nothing to do with merit.

Vendors change the workflow, not the obligation. Many large proceedings run fact sheet submission through a third-party platform, and the guide lists a long roster of proceedings that have done so. The vendor changes where the data goes and who bears the cost. It does not reduce the work of getting a complete, verified, authorization-backed fact sheet out of a claimant who has moved twice and does not remember which pharmacy filled a prescription in 2019. That part is human, it is repetitive, and it is exactly what a trained support team should be doing.

Records at volume is a different job than records on a file

Every plaintiff firm retrieves medical records. Mass tort retrieval is a different discipline because the failure mode changes with scale.

On one file, a records request that stalls is visible: the paralegal handling that case notices. Across 3,000 claimants, a stalled request is invisible unless someone is running an aging report. Requests go to hundreds of unrelated custodians per proceeding, each with its own release desk, turnaround, fee practice, and preferred format, plus pharmacy chains, employers, and insurers. There is no relationship to lean on and no memory to rely on.

What a working volume records operation actually requires:

• One tracker, not a folder of emails. Every request has a claimant, a custodian, a method, a date sent, a follow-up date, a status, a fee, and an owner. If that lives in anything other than a single queryable place, you cannot report on it and you therefore cannot manage it.
• Authorization lifecycle management. HIPAA authorizations expire, get superseded when a protocol changes, and get rejected for technical defects. At volume, re-execution is a recurring workflow with its own queue, not an exception.
• A follow-up cadence with escalation by age. Every five to seven business days is a defensible default. What matters more than the exact interval is that a request crossing thirty days triggers a named escalation rather than a shrug.
• Quality control on receipt. Missing pages, illegible copies, wrong patient, and date gaps are all common enough that inspecting on arrival is cheaper than discovering the problem when a fact sheet or a bellwether workup depends on it.
• A fee log. Custodian fees at inventory scale are a real cost line, and they are also the most common place where a firm's case expenses drift out of alignment with what it can document.

Firms already running this discipline for single-event work will recognize most of it from the personal injury medical records SLA playbook approach. The change at inventory scale is that the aging report stops being a nice management artifact and becomes the only way anyone knows what is happening.

The claimant database is the product

This is the part that firms new to mass tort consistently underinvest in, and it is the part that determines what everything else costs.

Every question that will be asked of your inventory over its life is a database question. Which claimants used the product in the relevant period. Which have the injury the science supports. Which are candidates for the discovery pool. Which have Medicare. Which are missing an authorization. Which have a fact sheet due in the next thirty days. Which have a deficiency open past the cure period.

If product identification, use dates, injury type, payer status, and fact sheet state live in structured fields, all of those questions take minutes. If they live in free-text notes and attachments, all of them take a person a week, and the answer is wrong. The most expensive version of this failure is discovering at fact sheet time that a meaningful share of the inventory was never screened against the criteria the firm thought it was using.

Practical consequences for staffing:

• Intake capture should be structured at the point of contact, not reconstructed later. Screening criteria belong in required fields with controlled values.
• Deduplication needs an owner. At volume, the same claimant reaching two intake channels is routine, and a duplicate that survives into a fact sheet process creates a problem that is expensive to unwind.
• Status fields need a definition document. "Pending" means nothing across 4,000 claimants unless there is one written answer to what it means and who changes it.
• Someone needs to run the completeness report weekly and work the gaps as a queue. This is a job. Give it to a person, not to everybody.

Firms scoping this from scratch can start with the law firm staffing calculator to size a team against actual queue volume rather than against a headcount guess.

Lien and settlement readiness starts at intake

The most common avoidable delay in mass tort is the gap between a settlement number and money reaching claimants. A large share of that gap is lien resolution, and most of it is a scheduling problem rather than a legal one.

The Medicare Secondary Payer process alone has enough built-in latency to justify starting early. Working from CMS's own published guidance for attorneys on conditional payment information:

• The process starts with a rights and responsibilities letter. The Benefits Coordination and Recovery Center then issues a conditional payment letter within 65 days of that letter, to the beneficiary and to authorized representatives with verified proof of representation on file.
• The conditional payment amount is interim, not final, because Medicare may keep making payments while the claim is pending.
• Claims believed unrelated to the injury claimed or released can be disputed with supporting documentation by mail, fax, or the Medicare Secondary Payer Recovery Portal, which requires registration before access.
• After settlement, a conditional payment notice replaces the conditional payment letter and carries a 30 calendar day window to respond with documentation. If nobody responds in that window, a demand letter issues for all related conditional payments without a proportionate reduction for fees and costs.
• Payment on a demand is due within 60 days of the demand letter date, and interest accrues from the demand letter date if it is not paid.

None of those steps require legal judgment to initiate. Proof of representation gets filed, the case gets reported, correspondence gets tracked, disputes get assembled with the supporting records already in the file. What requires an attorney is deciding what to dispute, what to accept, and how the resolution affects the client's net. That split is exactly why lien resolution support is one of the highest-return delegations in a mass tort practice: the clerical half is large, repetitive, and clock-driven, and the judgment half is small.

There is a related development on the defense and carrier side that plaintiff firms should understand even though the obligation is not theirs. Section 111 mandatory insurer reporting for non-group health plans now carries civil money penalties. Per CMS's NGHP civil money penalties page, the regulations were published October 11, 2023, became applicable October 11, 2024, and are enforced as of October 11, 2025, with tiered penalties of $250, $500, or $1,000 per day per record depending on how late the report is, capped at $365,000 for a single instance, and with quarterly audits of 250 randomly selected records beginning in January 2026. The practical effect for plaintiff firms is that responsible reporting entities are now more insistent about beneficiary identifiers and settlement details at settlement time. Having that data captured and verified in structured fields well before settlement removes a friction point that increasingly delays disbursement.

Common benefit submissions are an operations task with a deadline

Firms doing common benefit work in an MDL take on an administrative obligation that is easy to underestimate and expensive to fail.

Assessments in large proceedings are commonly set as a percentage holdback, generally in a range from about 3 to 11 percent of gross recovery, split between fees and expenses, with the assessment coming from counsel's share rather than the client's. Stanford's Center on the Legal Profession maintains a useful synthesis of court practice in its MDL Toolkit treatment of common benefit funds.

The operational requirements that follow from a typical common benefit order are unambiguous:

• Monthly submissions, often due by a fixed day of the following month, covering all work in the preceding month.
• Contemporaneous records, with specificity on hours, location, and activity, commonly in tenth-of-an-hour increments.
• Partner certification of accuracy.
• Receipts for expenses.
• Court-appointed CPA review, with authority to identify duplicative work and to recommend that non-compliant or unsubstantiated submissions be rejected or discounted, and with untimely submissions often rejected outright.

That is a recurring monthly production task with a hard deadline and a rejection risk, which describes a back office workflow rather than legal work. Time capture discipline, format compliance, receipt collection, assembly, and submission tracking are delegable to time entry and billing support. What is not delegable is the partner certification and the judgment about what work qualifies.

Federal is not the whole picture

A staffing plan built only around federal MDL practice will miss a substantial part of most inventories, because coordinated state proceedings run in parallel with their own orders and their own deadlines.

New Jersey designates multicounty litigation, assigning cases sharing common issues to a single judge for centralized management, under guidelines published in the Judiciary's Directive 08-12. California coordinates cases pending in different counties through civil case coordination, administered by the Judicial Council's coordination attorney at the direction of the Chief Justice, producing the numbered JCCP proceedings that frequently shadow large federal MDLs. Philadelphia runs mass tort programs through its Complex Litigation Center.

The operational point is not that state practice is harder. It is that a firm carrying claimants in a federal MDL and a parallel state proceeding is running two sets of orders, two fact sheet or profile form protocols, two deadline structures, and often two submission platforms, against one claimant database. If the database does not carry a proceeding field and the checklists are not maintained per proceeding, the errors are guaranteed and they will surface as missed deadlines.

Where the attorney line stays

Mass tort creates more pressure to blur this line than almost any other practice, because the volume is crushing and the individual tasks look clerical. The line should be written down before staffing, not after an incident.

Support staff can collect, chase, index, verify against a checklist, log, track deadlines, prepare drafts, and communicate status within defined boundaries. Attorneys decide case acceptance, direct and supervise the fact sheet process and take responsibility for what is served, make filing and dismissal decisions, choose what to dispute in a lien resolution, hold settlement authority, and give every piece of advice a claimant receives.

Two rules keep firms out of trouble at scale. First, a fact sheet is verified by the claimant and supervised by the attorney; support staff assemble it and never substitute their judgment for the claimant's answer. Second, any claimant contact that moves past status and scheduling into what the claim is worth, whether to accept, or what the law requires gets routed to an attorney the same day. Write both down, train to them, and audit against them.

What to delegate first, and in what order

For a firm moving from ad hoc coverage to a staffed mass tort back office, the sequence that produces the fastest reduction in risk is:

1. Fact sheet production and deficiency cure. Shortest fuse, hardest consequence, most measurable. One owner, a written checklist per proceeding, a daily deficiency touch, and an aging report against the cure period.
2. Records at volume. Highest raw volume and the queue that gates everything downstream, including bellwether workups and settlement valuation. Give it a tracker, a cadence, an escalation age, and a fee log.
3. Claimant database hygiene. Least visible, highest leverage. Structured capture at intake, deduplication, defined status values, and a weekly completeness report worked as a queue.
4. Lien file opening and payer correspondence. Start at intake, not at settlement. The clocks described above are the whole argument.
5. Settlement and common benefit administration. Add when a proceeding approaches resolution, and add it before the month you need it rather than during.

Firms sizing this against budget rather than against headcount instinct can model it with the legal staff cost calculator, and can use a written 90 day onboarding plan so new support staff reach independent queue ownership on a schedule instead of by osmosis.

The numbers worth watching

Five metrics, all producible from a case management system and a shared tracker, all responsive within weeks:

• Fact sheet compliance rate. Percentage of eligible claimants served within the court-ordered window. This is the headline number and the one to report to partners every week during an active protocol.
• Open deficiencies by age against the cure period. Not a count. A distribution. Anything approaching the cure deadline is an exposed claim and should be treated as one.
• Records requests aged past 30 days. Reviewed weekly, escalated by name, trended month over month.
• Lien files opened as a percentage of claimants with a known government payer. Should be at or near 100 percent for an inventory in its first year, not for one approaching settlement.
• Structured field completeness. Percentage of active claimants with product identification, use dates, and injury coded in fields rather than notes. This is the leading indicator for every other number on the list.

None of these require new software. All of them require an owner and a definition.

The honest summary

A mass tort inventory is a compliance operation with a litigation outcome attached. The legal questions in these proceedings are genuinely hard and genuinely belong to attorneys. The reason inventories lose value is almost never that the attorneys got the law wrong. It is that a fact sheet went out late, an authorization expired, a deficiency aged past its cure window, a records queue nobody was reporting on delayed a bellwether workup, or a lien file opened four months after it should have.

Every one of those is a staffing decision made in advance or a loss discovered afterward. Build the queues, name the owners, write the scope line down, and report on compliance rather than activity.

This article is general operational guidance for law firms and is not legal advice. Case management orders, fact sheet protocols, deficiency and cure procedures, lien resolution requirements, and unauthorized practice rules vary by proceeding and by jurisdiction and change over time. Verify current requirements against the orders governing your proceedings, the primary sources linked above, and your own bar before relying on any of it.
