California rules that put the audit trail at the center
The procedural rules below decide when the electronic record has to be authenticated, how long the evidence survives, and what happens when it has been altered. Each one is a reason to look at the audit trail early, not after the theory of the case is fixed.
Expert-evidence standard
California does not use Daubert. It applies the Kelly (Kelly-Frye) general-acceptance test to new scientific techniques, and under Sargon the trial judge is a gatekeeper who must exclude speculative or unreliable expert opinion.
Sargon Enterprises v. USC, 55 Cal.4th 747 (2012); People v. Kelly
Affidavit of Merit
California imposes no certificate or affidavit of merit for medical malpractice; instead a 90-day notice of intent to sue is required before filing (CCP 411.35 certificates apply to architects/engineers, not physicians).
CCP 364 · 90-day notice of intent (no merit affidavit)
Statute of limitations
The earlier of 1 year from discovery or 3 years from the injury, tolled for fraud, intentional concealment, or a non-therapeutic foreign body.
CCP 340.5
Record retention
Hospitals keep records 7 years (Cal. Code Regs. tit. 22, 70751); minors' records until 1 year after age 18, and never less than 7 years.
Spoliation & concealment
California recognizes no independent spoliation tort (Cedars-Sinai v. Superior Court) and addresses it through evidentiary and discovery sanctions and adverse-inference instructions.
How an EMR check fits a California case
- Authenticate the record. Before anyone interprets the chart, independent audit-trail analysis establishes whether it is complete, contemporaneous, and unaltered — the foundation an early merit assessment rests on.
- Go deeper than the chart. EMR metadata analysis covers the revision histories, device identifiers, and routing data behind the printed record, and shapes discovery demands the producing system can actually answer.
- Turn findings into testimony. The documented methodology carries through deposition prep and expert witness support — findings stated from the system's logs, in terms a trier of fact can follow.
What an engagement delivers
Audit trail & metadata findings
Entry-timing reconstruction, edit and deletion history, copy-forward detection, and user attribution — what changed, by whom, and when.
Revision-history reconstruction
Where a note exists in multiple states, the full sequence is rebuilt from the logs, separating a disclosed addendum from a silent alteration.
Discovery support & model RFP language
Request-for-production language tuned to the specific EMR, so you ask for what the system can actually produce — not an ambiguous label that invites objection.
Deposition prep & expert consulting
Outlines to question records custodians and IT witnesses, plain-language translation of the findings, and consulting or testifying expert support.
Completeness review
An access log shows who viewed the chart; an audit trail shows what changed. A focused review of what was produced, what's missing, and what to demand next.
Frequently asked questions
Do you provide EMR audit-trail analysis for cases in California?
Yes. EMRCheck supports California plaintiff attorneys with independent forensic analysis of EMR/EHR audit trails and metadata. The work is done on the records produced in discovery, so it isn't limited by venue within the state.
Will the analysis hold up under California's expert-evidence standard?
California does not use Daubert. It applies the Kelly general-acceptance test to new scientific techniques, and under Sargon Enterprises v. USC the trial judge is a gatekeeper who must exclude speculative or unreliable expert opinion. The analysis is drawn from the system's own logs and documented as a reproducible methodology built to withstand that review.
Does an EMR check satisfy California's merit / pre-suit requirement?
California imposes no certificate or affidavit of merit for medical malpractice; what is required is a 90-day notice of intent to sue before filing (CCP 364). An early audit-trail review still earns its place — it helps assess merit before the notice goes out and confirms the record it relies on is authentic and unaltered.
Given California's deadlines, will the audit trail still exist?
California's limitations period is the earlier of 1 year from discovery or 3 years from the injury (CCP 340.5), tolled for fraud, intentional concealment, or a non-therapeutic foreign body. Hospitals keep records 7 years (Cal. Code Regs. tit. 22, 70751), so audit-trail data is usually still retrievable — but the one-year discovery clock makes early review important.
