Coronavirus Disease 2019 (COVID-19) Clinical Data Repository

This is an effort to compile a repository of the clinical characteristics of patients who have taken a COVID-19 test. By sharing our schema and data, we hope that we can 1) accelerate information sharing among frontline healthcare providers and 2) facilitate studies on COVID-19 signs, symptoms, stages, and care plans.

The Repository

The repository is maintained as CSV files and is compliant with HIPAA Privacy Rule’s De-Identification Standard. Further, a patient’s reported age differs from their actual age by a reasonable randomized amount to protect their privacy.

The data includes clinical characteristics (epidemiologic factors, comorbidities, vitals, clinician-assessed symptoms, patient-reported symptoms), in addition to radiological and laboratory findings. It does not include treatment plans, complications, and clinical outcomes, which is collected at inpatient facilities. Details about each field are available in the data dictionary.

The data includes both positive and negative test results for symptomatic and asymptomatic patients. The data does not include results for patients with severe symptoms. We refer such patients to ER.

It is important to note that our data collection is clinically-driven and therefore not systematic. This means that overall positive rates are descriptive of the Carbon Health patient population and cannot be generalized to the unobserved population. We provide functions to identify symptom severity to aid in accounting for the various admission criteria that affect positive rates.

Refresh Cadence and Organization

Supplementary Material

Please note that the fill rates of vitals and clinician-assessed symptoms have dropped with the more recently published data batches due to the presence of a greater volume of mobile clinics, pop-up clinics, and home test kits. Clinicians are not present at these locations during the time of specimen collection, and therefore, vitals are not taken and exams are not provided.
