Mapping diagnostic error hot spots with public data

Diagnostic-error cases (missed/delayed diagnoses of cancers, infections, vascular events) are among the most severe and costly malpractice claims, driving a large share of catastrophic outcomes. That’s why venue matters: the same factual scenario can be priced—and litigated—very differently depending on the jurisdiction.

Below is a practical way to triangulate venue risk using public sources you can cite in a client update or underwriting memo.

1) Start with payouts: NPDB’s state map

Use HRSA’s NPDB Data Analysis Tool to view medical malpractice payment totals and medians by state, over time. Higher and rising payouts can signal a more plaintiff-favorable climate—even though NPDB isn’t diagnostic-error specific. Tip: compare 5-year trends rather than a single year; normalize by population when possible.

How to use it

  • Pull a five-year state view for “Medical Malpractice Payment Reports.”
  • Flag states with both above-median payouts and upward trends for deeper review (see Steps 2–4).

2) Check legal levers: AMA’s 50-state caps & reforms

The AMA State Laws Chart summarizes key liability-reform features (e.g., non-economic damage caps, wrongful-death caps, joint-and-several rules). States with no/low caps and plaintiff-friendly rules generally see higher verdict potential. Track recent changes (e.g., phased cap adjustments), which can shift venue dynamics quickly.

How to use it

  • Annotate your state list from Step 1 with: “caps/no caps,” “cap amount,” and any recent legislative updates.
  • Elevate states with no caps or high caps into your “watch” category—even more so if NPDB payouts are also elevated.

3) Layer venue climate: ATRA’s “Judicial Hellholes”

ATRA’s annual Judicial Hellholes® report highlights states and specific local courts with reputations for expansive liability or litigation tourism. It’s not med-mal specific, but it’s a useful venue-climate signal—especially for county/city hot spots mentioned by name.

How to use it

  • Cross-reference any state or county called out by ATRA with your NPDB/AMA short list.
  • If a city/county recurs in ATRA summaries year over year, treat it as a likely plaintiff-leaning venue and plan pricing/defense posture accordingly.

4) Go county-level: USLAW State Judicial Profiles

For granularity below the state level, USLAW’s State Judicial Profiles by County (biennial PDF) tags counties as Conservative / Moderate / Liberal and summarizes notable court dynamics. This is one of the few publicly accessible county-by-county references for general venue temperament.

How to use it

  • For multi-site provider groups, mark each facility’s county with the USLAW tag; contrast it with payer mix and claim mix.
  • Where county temperament skews more plaintiff-friendly and the state has no caps, consider higher retentions, tighter risk-management undertakings, or earlier resolution strategies.

5) Ground it in Dx-error reality: severity evidence

When explaining why venue vigilance is essential for diagnostic error, cite the literature: the “Big Three”—cancers, vascular events, infections—drive roughly three-quarters of serious misdiagnosis harms, and Dx-error claims are among the most severe and costly in malpractice. These are national data (not mapped), but they justify the venue lens.

A simple workflow you can replicate

NPDB map → shortlist high-payout states.

AMA chart → flag no/low-cap jurisdictions within that shortlist.

ATRA report → note any named hot-spot counties/courts in those states.

USLAW county profiles → tag your actual facility counties for venue temperament.

Explain stakes with Dx-error studies when briefing executives/insureds.

NPDB is not Dx-error specific; ATRA/USLAW are venue-climate proxies, not outcomes databases; true county-level Dx-error verdict mapping typically requires subscription verdict datasets plus local-counsel intel.
