Synthetic Patient Datasets

Not everyone has a de-identified patient record at hand to try the Context Engine with. The four datasets below are fully synthetic, so they describe no real person and hold no PHI. They range from a single admission to four and a half years of complex care, so you can pick the one that matches what you want to test.

Each archive holds bundle.json (a FHIR R4 collection bundle) and a cda/ folder of C-CDA XML documents that span the same timeline. Submit the bundle first and then each document to test resolution across formats. Either format also works on its own. The three pediatric archives also hold document_manifest.json, which lists every file with its SHA-256. Jeanne's bundle is also available on its own as fhir-bundle.json.

Jeanne TremblayCopy Anchor Link

Jeanne is a 72-year-old French-Canadian woman from Montreal with a decade-long clinical history anchored on severe COPD. Her record spans primary care, respirology, physiotherapy, gastroenterology, radiology and a recent emergency admission. That spread makes it a good test of entity resolution, deduplication across sources and condition stories.

Clinical timelineCopy Anchor Link

Her record covers ten episodes from 2017 to 2026:

1. 2017: Bilateral knee osteoarthritis is diagnosed and managed conservatively, with a physiotherapy referral.
2. 2019 (June): She receives a sequential PCV13 pneumococcal vaccination, after earlier priming with PPSV23.
3. 2019 (August): A screening colonoscopy removes two diminutive tubular adenomas, with surveillance recommended in 10 years.
4. 2020: The annual cardiovascular review finds her lipid panel near target and her renal function stable (eGFR 68).
5. 2022: She has an acute viral upper respiratory infection without COPD exacerbation, seen by telehealth, and recovers on her own.
6. 2023 (February): A baseline DEXA scan shows osteopenia at the femoral neck (T-score −1.9), with no anti-resorptive drug indicated.
7. 2023 (November): A vitamin D recheck is at target (78 nmol/L). An inhaler reconciliation confirms her triple COPD regimen.
8. 2024: A physiotherapy reassessment finds worsening right knee pain that limits walking to 15 minutes, and starts an 8-week strengthening program.
9. 2025: The annual respirology GOLD reassessment finds her stable, with FEV1 1.10 L (44% predicted), FEV1/FVC 0.48, a CAT score of 14 and GOLD group B.
10. 2026 (May): An acute COPD exacerbation leads to an emergency admission with SpO2 87% on room air, purulent sputum and compensated hypercapnia (pH 7.34). She is treated with controlled oxygen, nebulised bronchodilators, prednisone and doxycycline (because of her penicillin and sulfa allergies), and discharged after 48 hours.

Liam CarterCopy Anchor Link

Liam is a 9-year-old from Westerville, Ohio, with nine years of ordinary pediatrics and then one month in spring 2026 that generated more documentation than the previous nine years combined. His chart was written by three care teams (his pediatric practice, a children's hospital and a home infusion service), which each restate the same problems and medications in their own words at every visit. The record is built so that the answer to "what is true now" differs from what most individual notes say.

MedicationsCopy Anchor Link

Four home medications are current: fluticasone, albuterol, cetirizine and methylphenidate extended-release. Five peri-operative drugs stopped within a month and are restated as history in later notes:

Oxycodone is named in three notes and has no resource in the FHIR bundle, so submitting the bundle alone leaves it out. The home infusion admission note also lists oxycodone 2.5 mg as needed among his home medications, while the discharge summary says no opioid went home.

What to look for after ingestionCopy Anchor Link

• The current problem list should read asthma, ADHD and allergic rhinitis, with the surgical cluster under resolved. The appendicitis is restated once under a second heading, Gangrenous perforated appendicitis with localized peritonitis, which the operative encounter charts active and only the hospital records imported by the home infusion service resolve. Both headings describe the same appendix, which was removed.
• The current medication list should hold the four home medications only. Every antibiotic order and statement is stopped, and the as-needed acetaminophen and ibuprofen from discharge and a five-day prednisolone course from 2023 are completed. The admission note's ceftriaxone, metronidazole and amoxicillin-clavulanate are planned orders with the status draft.
• The pelvic drain and the PICC are Device resources placed and removed on known dates, and both go inactive when removed on 2026-04-24, so neither belongs in the current state.

Ava ReyesCopy Anchor Link

Ava is a 9-week-old from Dublin, Ohio, who was entirely well until RSV bronchiolitis at nine weeks. Her 4-year-old brother attends daycare. Her record is one admission long: an emergency assessment, four ward progress notes, a discharge summary, and a note from her pediatrician a week later. It is the smallest chart here and the one with the least to reconcile, so every approach should answer questions about it correctly.

ConditionsCopy Anchor Link

The 2026-09-21 follow-up charts all three problems as resolved. The children's hospital summary imported with it, which is a DocumentReference in the bundle rather than a C-CDA file, agrees.

What to look for after ingestionCopy Anchor Link

• The record holds no medications, no allergies and exactly three conditions. A fourth condition is a confabulation drawn from the family history or the sibling's wheeze.
• All three conditions should read resolved.
• The nasogastric tube was placed 2026-09-11 and removed 2026-09-13, so it belongs in the history.
• Apart from the newborn screens of 2026-07-10, every measurement comes from the admission or the 2026-09-21 visit. The current weight is 5.6 kg, measured at the 9/21 visit.
• Hepatitis B at birth is the only vaccine given. Nirsevimab and the 2-month series are charted not-done on 9/10 and 9/21, so "what is she due for" has an answer.

Mason WhitakerCopy Anchor Link

Mason is a 4-year-old from Columbus, Ohio, born at 25 weeks and 2 days weighing 720 g. His record is his whole life: a 314-day neonatal intensive care stay, three shunt revisions, two pneumonia admissions, three pediatric intensive care stays, and a care team that grew to eleven subspecialties. His chart was written by four services (a children's hospital, its home ventilation service, a pediatric rehabilitation center and his primary care pediatrician), with every consultant restating the same problem list from their own angle. The record is built so that the current answer to any concrete question (tube size, valve setting, ventilator settings, anticonvulsant dose) sits beside an older, superseded version of itself, restated many times.

DemographicsCopy Anchor Link

ConditionsCopy Anchor Link

Several problems are restated under two labels that disagree: the intraventricular hemorrhage is resolved under its own name and active under the merged "grade IV left … grade II right" heading, the neonatal seizures are resolved as "secondary to grade IV IVH" and active as "neonatal seizures, clinical", and the January 2025 RSV bronchiolitis with tracheitis is never marked resolved at all. These disagreements are in the record on purpose, for the Context Engine to reconcile.

MedicationsCopy Anchor Link

Thirteen medications are current, all but two given through the gastrostomy: levetiracetam 300 mg twice daily, clobazam 2.5 mg at bedtime, baclofen 5 mg three times daily, glycopyrrolate 0.6 mg three times daily, omeprazole 10 mg daily, polyethylene glycol 3350, cholecalciferol 1500 IU, ferrous sulfate 25 mg elemental, melatonin 3 mg, a peptide-based high-density formula, acetaminophen as needed, plus inhaled fluticasone and albuterol. Levetiracetam (100 → 150 → 300 mg), baclofen (2 → 5 mg) and glycopyrrolate (0.3 → 0.6 mg) each appear in several dose generations as weight rose. Only the latest is current. Four drugs stopped along the way and are restated as history in later notes:

Phenobarbital and lansoprazole were both stopped in 2023. Later notes keep restating them, always as stopped, so the restatements outnumber the active entries without changing the answer.

DevicesCopy Anchor Link

Seven device families are charted as Device and DeviceUseStatement resources, and most of them changed at least once: the tracheostomy tube (4.0 Bivona cuffless, then 4.5 Bivona flex from March 2025), the gastrostomy button (12 Fr, then 14 Fr from 2024), the ventriculoperitoneal shunt valve (2.5, then 1.5 after the 2024 revision and again at the March 2026 valve replacement), the home ventilator, bilateral hearing aids, a TLSO brace and a central venous catheter placed for IV antibiotics in 2023. Superseded entries stay active where the note that created them said so, even though only the newest entry of each family is current.

What to look for after ingestionCopy Anchor Link

• The current problem list should be dominated by the sequelae of prematurity (hydrocephalus, cerebral palsy, epilepsy, chronic respiratory failure and feeding), with retinopathy and the neonatal cluster under resolved.
• Device state is the sharpest test: the tracheostomy tube, the gastrostomy button and the shunt valve each have a current value and an older one restated many times, mostly as active devices. Only the latest is right.
• Nocturnal ventilator settings were escalated during the January 2025 RSV admission (peak PS 18/8, backup rate 28; PS 14/7, backup rate 22 at discharge) and stepped back down to the PS 12/6, backup rate 20 baseline that the February 2026 sleep study confirms. The notes in between disagree on purpose.
• Levetiracetam, baclofen and glycopyrrolate each carry several dose generations. Only the latest should be current.
• Growth is charted against corrected age, about 15 weeks behind chronological age, so raw percentiles get the trajectory wrong.

Dataset versionsCopy Anchor Link

Every dataset carries a version and a SHA-256 in manifest.json, alongside the hash of each file inside the archive. Use it to confirm which generation of a dataset you hold and whether your copy still matches what this site publishes:

curl -sO https://docs.clinia.com/samples/liam-carter.zip
curl -s https://docs.clinia.com/samples/manifest.json | jq -r '.datasets[] | select(.id=="liam-carter") | "\(.archive.sha256)  liam-carter.zip"' | shasum -a 256 -c

A dataset's version changes whenever its content does. A hash tells you that something changed, while the version tells you which generation you have. Benchmarks and demos that embed a copy of a dataset should pin its version and hashes rather than the files alone.

Ingest a datasetCopy Anchor Link

The Quickstart loads a dataset through the studio. Ingest and Query a Patient submits one through the API.

To submit a dataset yourself, create a patient first, using the dataset id (jeanne-tremblay, liam-carter, ava-reyes, mason-whitaker) or any patient ID you prefer. The ingest commands are in Ingest a FHIR Bundle and Ingest a CDA Document.
