Clean data. Safer patients. Stronger margins.
Chart correction, EMPI stewardship, HL7 error queue management, document QA, and release of information — delivered entirely inside the EHR you already own.
Dirty data is quietly expensive — and it’s a patient-safety issue first.
Most health systems carry a measurable data-integrity debt — created one registration, one interface error, and one misfiled document at a time.
Every module is a doorway.
Bad data doesn’t arrive all at once. It leaks in through five everyday workflows — each one mapped to a service we run.
Registration & ADT
What breaks: duplicates and overlays created at the front desk in seconds — a misheard name, a rushed search, a new record where one already existed.
What it costs: repeated tests, denied claims, and wrong-patient risk that compounds with every visit.
HL7 interfaces — ADT · ORU · MDM · DFT
What breaks: results, orders, documents, and charges stall in error queues across lab, imaging, cardiology, and billing modules.
What it costs: results that never file, charges that never drop, and clinicians charting blind.
Scanning & indexing
What breaks: documents filed to the wrong patient, encounter, or document type.
What it costs: “missing” records — and clinicians who stop trusting the chart.
Legacy conversion
What breaks: mis-mapped or partially converted clinical data at go-live.
What it costs: errors that persist in the new EHR for years — inherited by every clinician who opens the chart.
Release of information
What breaks: manual, backlogged fulfillment under HIPAA and state deadlines.
What it costs: compliance exposure, requester complaints, and staff churn.
Maintained integrity pays for itself.

without EMPI support
Denials shrink at the source
Identity errors drive 35% of denial volume — roughly $2.5M a year at the average hospital. Clean identity attacks the whole category.
Care stops repeating itself
Every duplicate prevented avoids ~$1,950 in redundant inpatient testing and delay — and gives clinicians one complete record to act on.
Safety and trust compound
When results file and documents land where they belong, clinicians trust the chart — and adoption, throughput, and satisfaction follow.
A one-time cleanup at a 150+ bed hospital averages more than five months. Daily stewardship means you never need one.
Six services. One team. Zero new software.
Ongoing data-integrity operations, staffed by HIM and integration specialists working inside your EHR — Epic, Oracle Health (Cerner), Veradigm (Allscripts), MEDITECH, and more.
Chart Correction
Wrong-chart entries, amendments, and result moves resolved to the correct patient and encounter — with a clean audit trail and root-cause feedback to registration and clinical teams.
Overlay Correction
Full separation of co-mingled records, line by line — structured correction plans with bill holds, portal deactivation, downstream notifications, and clinical review coordination. The work that takes internal teams up to 200 hours per record.
EMPI Maintenance
Daily duplicate worklists worked to zero, potential merges validated before auto-linking can create an overlay, and monthly integrity reporting: duplicate rate, aging, root causes.
Error Queue Management
HL7 interface errors — ADT, ORU, MDM, DFT — triaged and cleared daily across lab, imaging, cardiology, surgery, and billing. Every cleared error is a result filed or a charge captured.
Document Indexing & QA
Right patient, right encounter, right document type — misfiles re-indexed before clinicians hit them, sampling-based QA audits with error-rate reporting, and backlog burn-down when scanning teams run short.
Release of Information
Requests logged, validated, and fulfilled in your EHR’s ROI module — HIPAA and state turnaround compliance tracked and reported, QA on every release, all requester types covered.
The market leaders run platforms. We run your EHR.
National ROI vendors retrieve tens of millions of records a year — on their platforms, through their networks. Our model is built on yours.
Typical platform vendor
- PHI exported into the vendor’s platform and national network.
- Their portal, their interfaces, their implementation project.
- Records flow through a health-data exchange business.
- Activity logged on the vendor’s systems.
Chesapeake Systems
- PHI never leaves your EHR or your security perimeter.
- The ROI module and reports you already own — nothing to implement.
- No data business — your data is never our product.
- Every action in your audit trail, under your access controls. Trained specialists working in weeks.
Your EHR. Your reports. Nothing else.
The same model runs across every service — operations and projects alike.
No new software
We work in the identity, HIM, interface, and ROI tools you already license — nothing to buy, install, or interface.
PHI stays home
Your environment, your access provisioning, your audit trails. Data never crosses into a vendor platform.
Reports you already run
Duplicate worklists, error queues, and standard reports drive the work — results visible in your own numbers.
Elastic by design
Scale up for a backlog, a cleanup, or a go-live. Scale down for steady state. Pay for work performed.
When the work is a mountain, not a stream.
Clinical Data Conversion
Legacy clinical data mapped, converted, and loaded — allergies, medications, problems, immunizations, results — clinically meaningful on arrival, not just technically present. Vendor coordination from extract through ingestion.
Our conversion approach →Conversion Validation
Independent, field-level validation of converted data against the legacy record. 100% is the only acceptable pass rate for medications and allergies — discrepancy queues worked to resolution before go-live.
Manual Data Abstraction
Credentialed abstractors building complete patient profiles from legacy EHRs, paper charts, and lab and radiology systems — go-live chart prep, registries, quality reporting, and hybrid conversions where automation can’t reach.
Why this work goes to specialists.
There’s no bench to borrow
HIM teams are sized for steady state, and the field carries persistent shortages with ~15% projected role growth. When a conversion or cleanup lands, the surge staff simply isn’t there.
Clinicians are the wrong tool
Validation and abstraction pushed onto providers costs up to 30% of their productivity for months — and specialist rates run well below clinician overtime.
Repetition builds accuracy
Teams that correct, convert, validate, and abstract every day bring proven playbooks, QA discipline, and zero learning curve on your dime.
Rigor moves the number
Organizations that test and validate thoroughly cut post-migration issues by roughly 60% — the single biggest lever in project outcomes (ONC).
