# Synthetic Patient Datasets URL: https://docs.clinia.com/docs/patients/synthetic-patient-datasets > Download fully synthetic patient records to try the Context Engine without real patient data. 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. | Dataset | Patient | What it exercises | Size | | --------------------------------------------------- | ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------- | | [jeanne-tremblay.zip](https://docs.clinia.com/samples/jeanne-tremblay.zip) | Jeanne Tremblay, 72, Montreal | A decade of chronic disease across six specialties: cross-source entity resolution, deduplication, condition stories | FHIR bundle + 20+ C-CDA documents | | [liam-carter.zip](https://docs.clinia.com/samples/liam-carter.zip) | Liam Carter, 9, Ohio | One surgical episode on nine years of pediatric background: problems that resolve, medications held and restarted, courses that end | FHIR bundle (355 resources) + 22 C-CDA notes | | [ava-reyes.zip](https://docs.clinia.com/samples/ava-reyes.zip) | Ava Reyes, 9 weeks, Ohio | The simplest chart: one four-night admission, almost no history before it and nothing to reconcile | FHIR bundle (113 resources) + 7 C-CDA notes | | [mason-whitaker.zip](https://docs.clinia.com/samples/mason-whitaker.zip) | Mason Whitaker, 4, Ohio | The most complex chart: four and a half years of care after extreme prematurity, eleven subspecialties restating one problem list, devices and doses changed mid-record | FHIR bundle (2,641 resources) + 101 C-CDA notes | 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](https://docs.clinia.com/samples/fhir-bundle.json). ## Jeanne Tremblay [#jeanne-tremblay] 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. ### Demographics [#demographics] | Field | Value | | ------------- | ---------------- | | Date of birth | 1953-04-12 | | Gender | Female | | Location | Montreal, Quebec | | Language | English | ### Allergies [#allergies] | Allergen | Reaction | Severity | | ----------------- | ----------------------- | -------- | | Penicillin | Diffuse urticarial rash | Moderate | | Sulfa antibiotics | Maculopapular rash | Mild | ### Active conditions [#active-conditions] | Condition | Onset | | ----------------------------------------------------- | ----- | | COPD, GOLD stage 3 (severe) | 2014 | | Hypertension | 2011 | | Dyslipidemia | 2013 | | Bilateral knee osteoarthritis (right worse than left) | 2017 | | Vitamin D deficiency | 2019 | | Osteopenia at femoral neck | 2023 | ### Current medications [#current-medications] | Medication | Dose | Route | Since | | --------------------- | --------------- | ------- | ----- | | Tiotropium | 18 mcg daily | Inhaled | 2015 | | Budesonide/formoterol | 200/6 mcg BID | Inhaled | 2018 | | Salbutamol | 100 mcg PRN q4h | Inhaled | 2014 | | Ramipril | 10 mg daily | Oral | 2012 | | Amlodipine | 5 mg daily | Oral | 2011 | | Atorvastatin | 40 mg QHS | Oral | 2013 | | Cholecalciferol | 1000 IU daily | Oral | 2019 | | Acetaminophen | 500 mg PRN q6h | Oral | 2017 | ### Clinical timeline [#clinical-timeline] 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 Carter [#liam-carter] 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. ### Demographics [#demographics-1] | Field | Value | | ------------- | ----------------- | | Date of birth | 2017-03-18 | | Gender | Male | | Location | Westerville, Ohio | | Language | English | ### Conditions [#conditions] | Condition | Status at the end of the record | Notes | | ---------------------------------------- | ------------------------------- | ---------------------------------------------------------------------------------------------------- | | Mild persistent asthma | Active | Since 2021, on a daily inhaled corticosteroid that shaped the anesthetic plan | | Attention-deficit/hyperactivity disorder | Active | Since 2024, methylphenidate ER held during the admission and restarted at discharge | | Seasonal allergic rhinitis | Active | Since 2022 | | Acute perforated appendicitis | Resolved | Laparoscopic appendectomy 2026-04-07; charted active through the admission, resolved from 2026-04-14 | | Post-operative pelvic abscess | Resolved | Drained 2026-04-12, drain out 2026-04-24, clear ultrasound 2026-05-06 | | Post-operative ileus | Resolved | Gone by the second day after surgery | | Viral-triggered asthma exacerbation | Resolved | One emergency visit, October 2023 | ### Medications [#medications] 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: | Medication | Course | Route | | ----------------------- | ------------------------ | --------------------------- | | Piperacillin-tazobactam | 2026-04-06 to 2026-04-14 | IV, inpatient | | Ceftriaxone | 2026-04-14 to 2026-04-24 | IV via PICC, at home | | Metronidazole | 2026-04-14 to 2026-04-24 | Oral, at home | | Amoxicillin-clavulanate | 2026-04-24 to 2026-05-01 | Oral | | Oxycodone | 2026-04-07 to 2026-04-09 | Oral, three inpatient doses | 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 ingestion [#what-to-look-for-after-ingestion] - 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 Reyes [#ava-reyes] 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. ### Demographics [#demographics-2] | Field | Value | | ------------- | ------------ | | Date of birth | 2026-07-09 | | Gender | Female | | Location | Dublin, Ohio | | Language | English | ### Conditions [#conditions-1] | Condition | Status at the end of the record | Notes | | ------------------------------------------ | ------------------------------- | ------------------------------------------------------------------------------------------------------- | | Acute RSV bronchiolitis | Resolved | Admitted 2026-09-10, high-flow nasal cannula 2026-09-11 to 2026-09-13, resolved at discharge 2026-09-14 | | Mild dehydration secondary to poor feeding | Resolved | Corrected on nasogastric feeds, resolved at discharge | | Physiologic neonatal jaundice | Resolved | The only problem before the admission | 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 ingestion [#what-to-look-for-after-ingestion-1] - 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 Whitaker [#mason-whitaker] 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. ### Demographics [#demographics-3] | Field | Value | | ------------- | ---------------------- | | Date of birth | 2022-03-02 | | Gender | Male | | Location | Columbus, Ohio | | Language | English | | Birth | 25 weeks 2 days, 720 g | ### Conditions [#conditions-2] | Condition | Status at the end of the record | Notes | | --------------------------------------------------------------------------------------- | ------------------------------- | --------------------------------------------------------------------------------------------------------------------------- | | Post-hemorrhagic hydrocephalus, shunt-dependent | Active | Grade IV intraventricular hemorrhage on day 4 of life; shunt revisions in April 2023, May 2024 and March 2026; valve at 1.5 | | Spastic quadriparetic cerebral palsy, GMFCS level V | Active | Non-ambulatory, on baclofen and serial botulinum toxin injections since 2024 | | Symptomatic focal epilepsy | Active | Levetiracetam and clobazam; breakthrough cluster February 2026 | | Severe bronchopulmonary dysplasia, chronic respiratory failure | Active | Tracheostomy since 2022, nocturnal home ventilation, off the ventilator by day | | Gastrostomy with fundoplication, oropharyngeal dysphagia | Active | All nutrition by gastrostomy | | Neuromuscular scoliosis, neuromuscular hip dysplasia | Active | Radiograph surveillance; TLSO brace for sitting balance; hip reconstruction decision due December 2026 | | Cortical visual impairment, bilateral sensorineural hearing loss | Active | Hearing aids since 2023 | | Iron deficiency anemia, vitamin D insufficiency, faltering growth | Active | Weight below the 3rd percentile | | Sialorrhea, global developmental delay, gastroesophageal reflux | Active | The chronic background every service restates | | Aspiration pneumonia | Resolved | Admissions in August 2023 and November 2024, both to intensive care, which later notes restate as prior episodes | | Central-line-associated bloodstream infection | Resolved | The 2023 intensive care episode | | Retinopathy of prematurity, stage 3 | Resolved | Laser treatment in 2022, with residual myopia carried forward as its own active problem | | Patent ductus arteriosus, necrotizing enterocolitis, neonatal sepsis, neonatal seizures | Resolved | The neonatal cluster, all onset and resolved inside the first year | 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. ### Medications [#medications-1] 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: | Medication | Course | Why it ended | | ------------- | ----------------------- | ----------------------------------------------------------------------- | | Phenobarbital | 2022 to 2023 | Replaced by levetiracetam | | Lansoprazole | 2022 to 2023 | Inpatient formulary substitution to omeprazole, continued at discharge | | Furosemide | 2023 to 2024 | Discontinued | | Palivizumab | 2022 to 2023 RSV season | One season. A nirsevimab dose for the next season is charted `not-done` | 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. ### Devices [#devices] 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 ingestion [#what-to-look-for-after-ingestion-2] - 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 versions [#dataset-versions] Every dataset carries a version and a SHA-256 in [manifest.json](https://docs.clinia.com/samples/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: ```bash 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 dataset [#ingest-a-dataset] The [Quickstart](https://docs.clinia.com/docs/get-started/quickstart) loads a dataset through the studio. [Ingest and Query a Patient](https://docs.clinia.com/docs/get-started/ingest-and-query-a-patient) submits one through the API. To submit a dataset yourself, [create a patient](https://docs.clinia.com/docs/patients/create-and-manage-patients#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](https://docs.clinia.com/docs/recorded-memory/ingest-fhir) and [Ingest a CDA Document](https://docs.clinia.com/docs/recorded-memory/ingest-cda).
