Streamlining Loss Run Report Analysis for Aggregate Risk Trends in Workers Compensation, General Liability & Construction, and Commercial Auto — A Risk Analyst’s Guide

Streamlining Loss Run Report Analysis for Aggregate Risk Trends — What Every Risk Analyst Needs Now

Risk analysts across Workers Compensation, General Liability and Construction, and Commercial Auto are being asked to do more with less: analyze larger books of business, uncover portfolio risk drivers faster, and support renewal strategy with defensible insights. The challenge is clear. Loss run reports arrive in inconsistent formats from multiple carriers and TPAs, claims history summaries are dense and idiosyncratic, and loss ratio reports often mix timeframes, accident years, and accounting conventions. Turning all of this into clear, aggregate loss run trends for risk management feels like a perpetual scramble.

Nomad Data’s Doc Chat changes the equation. It is a suite of insurance‑specific, AI‑powered agents that ingest entire claim files and document sets at scale, normalize the data, and summarize loss runs automatically — surfacing portfolio‑level drivers of frequency, severity, closure rate, and reserve adequacy in minutes. For risk analysts supporting underwriting managers and renewal strategists, Doc Chat delivers instant, explainable insights that move the conversation from What happened? to What should we do next?

Why loss run analysis is uniquely difficult for a Risk Analyst in today’s lines of business

On paper, loss run reports should be simple: date of loss, paid indemnity and expense, current reserves, cause of loss, claim status. In practice, a risk analyst is confronted with a heterogeneous mix of document types and coding systems across Workers Compensation, General Liability and Construction, and Commercial Auto. Each line demands different lenses, benchmarks, and context to extract reliable, comparable insights.

Workers Compensation

In Workers Compensation, loss run reports and claims history summaries must reconcile lost time versus medical-only claims, NCCI or WCIRB class codes, and development patterns by injury type. Trend analysis is complicated by reopened claims, litigation transitions, and medical inflation that can distort incurred loss trends if you do not separate indemnity, medical, and allocated loss adjustment expense. Analysts also need to parse experience mod worksheets, OSHA logs, nurse case management notes, and medical reports to understand causation and future exposure. The volume, variability, and critical nuances make manual comparison and aggregation slow and error-prone.

General Liability and Construction

For General Liability and Construction, risk is tied to project phases, subcontractor mix, wrap‑up programs like OCIPs and CCIPs, and contractually transferred exposures. Loss ratio reports rarely align to a single structure; you are balancing primary GL, Products/Completed Operations, and premises liability, often with endorsements that subtly change trigger language or aggregates mid‑term. Claims are noisy: bodily injury with legal expense spikes, property damage with subrogation recovery, and defect claims with long lag and highly contested causation. Analysts must reconcile policy schedules, certificate of insurance requirements, endorsements, and defense cost allocations to detect where severity risk is emerging.

Commercial Auto

Commercial Auto adds its own complexity: driver rosters, VIN-level schedules, MVR checks, DOT inspection history, telematics patterns, radius and route profiles, and nuclear verdict exposure in specific venues. Calendar year versus accident year comparisons can mislead without rolling accident‑to‑reporting lags. You often need to normalize loss runs from different TPAs who code causes of loss differently, and separate third‑party bodily injury from first‑party physical damage to get an apples‑to‑apples view of severity trends by vehicle class.

Across all three lines of business, the risk analyst job is fundamentally an inference problem, not a simple reading task. You must stitch together concepts that are scattered across loss run reports, loss ratio reports, claims notes, and policy endorsements to construct a single, actionable portfolio narrative that will stand up in renewal negotiations.

How loss run analysis is handled manually today — and why it breaks at scale

The current state is a patchwork of spreadsheets, ad‑hoc macros, and late nights. Brokers and carriers deliver loss run reports in PDFs, spreadsheets, and portal exports with different column headers, reserve practices, and accident vs. report year conventions. Risk analysts typically copy and paste fields into a master workbook, build VLOOKUPs to map coverage codes to a common taxonomy, and run pivot tables to compute rolling frequency and severity. Every exception multiplies the work: duplicate claim numbers across policy years, claims that reopen, reserves that inflate without explanation, and claims with split file numbers across TPAs.

There are also governance hurdles. Without a standardized process, it is hard to defend why certain claims were capped, why AY versus PY was used in a given chart, or how salvage and subrogation netting impacted loss ratio calculations in the past 12 months. It is even harder to perform longitudinal comparisons for portfolios spanning thousands of accounts or to deliver aggregate loss run trends for risk management that are timely enough to influence renewal strategy. When volume spikes, analysts resort to sampling — which introduces blind spots and increases the chance of missing emerging risks.

Manual reviews tend to focus attention on what is easy to count rather than what is strategically important. That is why organizations struggle to answer questions like: Which GL projects are driving late‑reported severity? Which WC body parts are creating reserve creep post‑surgery approvals? Which Auto venues correlate to rising defense costs despite stable frequency? The data is there — scattered across claims history summaries and loss run reports — but extracting and synthesizing it consistently is beyond what spreadsheets can handle under real-world deadlines.

How Doc Chat summarizes loss runs automatically and standardizes your portfolio view

Doc Chat by Nomad Data ingests complete document sets for every account — loss run reports, claims history summaries, loss ratio reports, policy schedules, endorsements, bordereaux, FNOL forms, and even ISO claim reports — in one pass. It then applies a standardized, insurer‑specific taxonomy to normalize fields like cause of loss, injury type, claim status, coverage parts, and expense buckets. The system builds a transparent audit trail with page‑level references to every number it extracts, enabling risk analysts to click from a portfolio KPI back to the exact document line where the value originated.

With this foundation, Doc Chat produces portfolio and account summaries in the formats your team already uses. Ask natural‑language questions across massive document sets: summarize loss runs automatically for all construction wrap‑ups over the last five years; show AI analysis loss run reports insurance for Workers Compensation by class code with paid, incurred, and reserve development deltas; rank Commercial Auto fleets by nuclear‑verdict venue exposure. The answers come with citations and can be exported to your data warehouse or BI tools with the exact field mapping your renewal strategy requires.

What Doc Chat extracts, reconciles, and computes out of the box

Doc Chat turns unstructured, inconsistent loss documentation into a clean, analysis-ready portfolio model. Typical extractions include:

• Core claim fields: claim number, policy number, policy period, date of loss, report date, litigation status, closure status, reopen flags
• Financials: paid indemnity, paid medical, paid expense, outstanding reserves by bucket, total incurred, recoveries, salvage and subrogation, ALAE vs ULAE where available
• Coding: WC class codes, GL hazard categories, Auto vehicle class, cause of loss, body part and nature of injury, claim type
• Operational signals: adjuster notes references, reserve change timelines, average days open, time‑to‑reporting, lag distributions
• Policy context: deductibles, SIRs, per‑occurrence and aggregate limits, endorsements altering defense inside/outside limits
• Derived metrics: frequency per exposure base, severity by claim type, closure rate velocity, reserve adequacy signals, trend lines by accident year, policy year, and calendar year

The system then computes portfolio‑level views by line of business with side‑by‑side comparability, solving the biggest barrier to aggregate loss run trends for risk management — cross‑carrier, cross‑TPA normalization.

Real-time Q&A and explainability at scale

Doc Chat’s real-time question and answer capability allows a risk analyst to interrogate thousands of pages instantly. Ask List the top 10 accounts with rising incurred but flat paid in Workers Compensation over the past 24 months, or Which Construction OCIP has severity spikes in Products/Completed Ops post‑completion. In seconds, you receive a ranked list with metrics and hyperlinks back to the source pages. This is not a black box. Every conclusion is traceable, defensible, and consistent with your organization’s playbooks.

This capability is exactly the shift discussed in Nomad Data’s perspective on advanced document automation. Document scraping is about inference, not location — a crucial difference when analyzing loss runs across thousands of accounts.

Use cases by line of business for a Risk Analyst

Workers Compensation: class code clarity and medical severity watch

Doc Chat pinpoints frequency changes by class code and shifts in medical severity for key injury categories. It highlights reserve creep following major medical interventions, reconciles reopened claims, and reveals whether days‑open and closure velocity are drifting. It also differentiates indemnity and medical trends so that inflationary effects and fee schedule changes are not mistaken for deteriorating claim handling. The result: sharper renewal narratives with quantified drivers that underwriters can price accurately.

General Liability and Construction: wrap‑up risk and defense‑cost control

For GL and Construction, the platform aggregates claims across OCIPs and CCIPs, controlling for project phase and completion dates. It isolates defense cost inflation, identifies late‑reported severity in Products/Completed Ops, and reconciles endorsements that move defense inside limits mid‑term. With clean visibility into premises versus products causes of loss, and subcontractor‑related incidents, risk analysts can articulate where contractual transfer programs are working — and where they are not.

Commercial Auto: venue severity, driver mix, and nuclear verdicts

In Commercial Auto, Doc Chat segments losses by venue, vehicle class, and driver cohort to uncover where severity is escalating regardless of frequency. It correlates time‑to‑reporting, litigation flags, and defense spend to identify clusters with nuclear‑verdict risk. Analysts can tie loss development to specific policy changes, driver onboarding processes, or route adjustments — strengthening both risk control recommendations and renewal positioning.

From days to minutes: how the manual steps disappear

Without automation, risk analysts spend the majority of time preparing the data rather than producing insight. Doc Chat removes the friction:

• Ingests entire claim files, loss run reports, loss ratio reports, and claims history summaries at once — including giant PDFs and mixed-format exports
• Classifies documents by line of business and account, normalizes fields to your taxonomy, and deduplicates across carriers and TPAs
• Performs automatic exception handling for reopened claims, split file numbers, and reserve restatements with side-by-side version tracking
• Generates standardized summaries and dashboards, aligned to your renewal and stewardship templates
• Supports real-time Q&A, with page-level citations so every metric is defensible

These end‑to‑end capabilities mirror what Great American Insurance Group experienced when accelerating complex claims with AI — shifting from days of searching to seconds of answering, with page-level explainability. See their story: Reimagining Insurance Claims Management.

Quantifiable business impact for renewal strategy and risk governance

When you can summarize loss runs automatically across thousands of accounts, the business impact cascades across underwriting, finance, and risk control.

Time savings: Analysts routinely report that a five-hour portfolio consolidation shrinks to minutes. Complex multi‑year, multi‑carrier portfolios once sampled can now be fully analyzed, eliminating blind spots. Cost reduction follows: less manual data preparation, fewer external consultants for crisis sprints, and fewer rework cycles ahead of renewals.

Accuracy and consistency: With AI analysis loss run reports insurance, reserve adequacy signals are computed the same way every time; closure rates, lags, and severity distributions are standardized; and loss ratio components are decomposed with clear treatment of salvage and subrogation. The result is an auditable, repeatable process that stands up to internal model governance and external partner scrutiny.

Strategic leverage: Aggregate loss run trends for risk management become the backbone of renewal narratives. You can quantify the impact of specific controls introduced last year, demonstrate improvement in closure velocity, or isolate venue‑driven defense spend increases. This clarity improves pricing discussions with underwriters, supports reinsurance negotiations with credible bordereaux analytics, and enables targeted risk engineering investments where they will move the needle.

Security, explainability, and audit readiness by design

Any tool that processes loss run reports must meet stringent standards for data security and governance. Nomad Data operates with enterprise‑grade controls, traceability, and page‑level citations for every extracted value. Outputs include calculation breakdowns and document references so findings can be validated in seconds. These features align with the rigorous, regulator‑ready posture described in Nomad’s claims transformation overview.

Doc Chat in the real world: sample questions a Risk Analyst can answer in seconds

Because Doc Chat supports portfolio‑wide, natural‑language Q&A, risk analysts can move from raw documentation to judgment quickly. Common prompts include:

• Show aggregate loss run trends for risk management by line of business for the last three policy years, normalized for exposure growth.
• Identify Workers Compensation claims with reserve growth exceeding 40 percent in the last 90 days and flag associated medical procedures.
• Rank Construction wrap-ups by late‑reported severity and show endorsements altering defense inside limits mid‑term.
• Highlight Commercial Auto accounts with rising defense costs in venues known for nuclear verdicts, controlling for frequency.
• Produce an account stewardship deck summarizing paid, incurred, lag, closure rate, and top causes of loss with citations.

Each answer links to the specific loss run report page, claim note, or endorsement where the evidence resides. That makes your renewal narrative fast to generate and easy to defend.

Implementation: white‑glove service, your playbooks, and a 1–2 week timeline

Doc Chat is not a one‑size‑fits‑all widget. Nomad Data trains the system on your playbooks, templates, and taxonomies so outputs align with how your organization measures risk. The engagement follows a white‑glove model:

Step 1: Discovery and scoping. We inventory your document sources — carrier and TPA loss run reports, claims history summaries, loss ratio reports, and supporting artifacts such as policy schedules and endorsements. We capture your definitions for severity capping, lag windows, reserve adequacy thresholds, and loss ratio formulas.

Step 2: Customization. We implement presets that produce standardized portfolio summaries, stewardship outputs, and cross‑line dashboards. We codify treatment of salvage and subrogation, AY vs PY views, and per‑line nuances such as WC medical versus indemnity separation.

Step 3: Go‑live and integration. Risk analysts can start immediately via drag‑and‑drop ingestion. Many clients integrate with claims systems and data warehouses within 1–2 weeks using modern APIs, with the platform scaling automatically as volumes grow.

Step 4: Evolve together. As your renewal strategy shifts or new lines are added, we update presets and taxonomies so every analysis remains consistent and audit‑ready.

This pragmatic, fast‑track approach mirrors the rollouts described in Nomad’s client stories and webinar replay content, where teams move from pilot to production in weeks — not quarters.

How Doc Chat compares to generic tools — and why that matters for loss runs

Generic OCR or summarization systems were designed for fixed layouts and predictable fields. Loss runs from different carriers and TPAs do not behave that way. Formats change, field names vary, and the information you truly need is often implied across multiple pages. As Nomad highlights in Beyond Extraction, document intelligence for insurance is about inference — reconstructing internal, insurer‑specific concepts from scattered details. Doc Chat was engineered for this reality, which is why it can analyze entire claim files and still produce consistent, defendable outputs.

Additionally, the platform is built with insurance‑grade explainability: page‑level citations, calculation logs, and end‑to‑end traceability. That is how a risk analyst can walk an underwriter through the rationale for a renewal ask, with evidence in view at every step.

Key outcomes for Risk Analysts and renewal stakeholders

Organizations adopt Doc Chat to achieve specific, measurable outcomes:
