About this study

This cohort study will obtain electronic health record (EHR) data (limited data set) from 21 health systems affiliated with the Cancer Center Cessation Initiative (C3I) network or health systems with large numbers of COVID-19 patients to explore whether smoking status, cancer history, and other risk factors among patients diagnosed with COVID-19 are associated with mortality and/or COVID-19 disease severity/complications. Each site will provide data from their health system EHR on a regular basis that includes all patients identified as having COVID-19 at some point in the interval from February 1, 2020, through January 31, 2022.

Read the detailed description

This cohort study will obtain electronic health record (EHR) data (limited data set) from 21 health systems affiliated with the Cancer Center Cessation Initiative (C3I) network or health systems with large numbers of COVID-19 patients to explore whether smoking status, cancer history, and other risk factors among patients diagnosed with COVID-19 are associated with mortality and/or COVID-19 disease severity/complications. The Cancer Center Cessation Initiative (C3I) is a project launched by the US National Cancer Institute (NCI) to improve the rate at which NCI-designated Cancer Centers provide evidence-based smoking cessation to patients diagnosed with and treated for cancer. The C3I is coordinated at the University of Wisconsin-Center for Tobacco Research and Intervention (UW-CTRI) and the University of Wisconsin Carbone Cancer Center (UWCCC). Twenty-one health systems across the U.S. will provide EHR data to the UW-CTRI coordinating center on all COVID-19 patients identified during the period from February 1, 2020, through January 31, 2022.

Current EHR-based data elements collected will include:

Evidence of COVID-19: ICD-10-CM diagnosis of COVID-19, COVID-19 PCR lab test, and/or COVID-19 antigen lab test

Healthcare system encounter type: inpatient, outpatient, emergency department (ED), urgent care, or other

SES/Demographics variables: insurance status, education, housing status, sex, age, race/ethnicity, height, weight, body mass index

Comorbid diseases: chronic asthma, chronic COPD, chronic bronchiectasis, diabetes mellitus, cardiovascular disease, chronic renal disease, on dialysis, immunocompromised [due to SLE lupus, rheumatoid arthritis, organ transplant, HIV, Crohn's], pregnant, cancer (lymphomas, leukemias, lung/respiratory, rectal, breast, prostate, pancreas), hypertension, depression, anxiety, alcohol abuse, pro- clotting disorders, and anti-clotting disorders

Tobacco use variables: smoking status (current, former, never), passive smoke exposure for never smoker, years since quitting (for former smokers), packs smoked per day, years of smoking, pack years, smokeless tobacco user, and marijuana use

Signs and symptoms: temperature, pulse, systolic blood pressure, diastolic blood pressure, oxygen saturation, septic shock, pneumonia, chills, muscle aches/myalgia, rhinorrhea, sore throat, chronic cough, shortness of breath, nausea or vomiting, headache, abdominal pain, diarrhea, dizziness, impaired consciousness, acute cerebrovascular event, ataxia, seizure, taste impairment, smell impairment, vision impairment, nerve pain, and skeletal muscular pain

COVID-19 treatment variables: ICU admission, required supplemental oxygen, intubated for ventilator use, noninvasive positive pressure, and number of days hospitalized

COVID-19 medications including (but not limited to): chloroquine, hydroxychloroquine, tocilizumab, remdesivir, dexamethasone, convalescent plasma, and ascorbic acid

Classes of other medications used: nicotine replacement therapies (NRTs), varenicline medications; blood thinners, steroids, angiotensin converting enzyme (ACE) inhibitors, angiotensin-receptor blockers (ARBs), short-acting adrenergic bronchodilators, long-acting adrenergic bronchodilators, anticholinergic bronchodilators, bronchodilators combos, inhaled corticosteroids (includes combo medications), and inhaled corticosteroid bronchodilators

Lab tests: COVID-19 PCR test, COVID-19 Antigen test, Albumin, ALT, Bicarbonte, BUN, Calcium, C-Reactive Protein, High Sensitivity, C-Reactive Protein, Creatinine, D-DIMER, ESR, Ferritin, Hematocrit, HgbA1c., INR, LDH, Leukocytes, Platelet Count, Potassium, Procalcitonin, Sodium, Troponin-I, Troponin-T

For the initial paper(s) to be prepared based on these data, the main analytic methods will include GUIDE classification and regression tree models. However, whole sample methods will also be used as complementary analytic methods, which will vary with regard to outcome type: i.e., logistic regression for binary outcomes and Cox proportional hazard analyses for time-to-event outcomes. Initial analyses will focus on hospitalized COVID-19 patients. Later waves of analyses may use different analytic approaches and address different questions.

Study groupRoleWhat they receive
Patients with COVID-19Analyses of the cohort data will include (1) all patients, or (2) hospitalized patients meeting specific inclusion criteria.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mortality due to COVID-19

    In analyses of hospitalized patients, all-cause mortality in patients with COVID-19 illness vs discharge from hospital (binary outcome)

    Measured: February 1, 2020, through January 31, 2022

  2. COVID-19 Severity

    In analyses of hospitalized patients, COVID-19 severity as measured by intubation for respiratory support (i.e., patient required intubation during hospitalization; binary outcome)

    Measured: February 1, 2020, through January 31, 2022

Individual data sharing
Yes: The Limited data set will be secured, cleaned, harmonized, and undergo initial analyses in mid to late 2022.The existing Data Transfer and Use Agreements (DTUA) negotiated with each 21 participating health systems precludes the University of Wisconsin (UW) from sharing these data with any entity at this time. This was a requirement of the UW IRB prior to transferring the de-identified site data sets to UW. Starting in 2023, investigators desiring access to CEC-UW data will need to apply for access via an NCI contractor organization, Information Management Services (IMS; https://www.imsweb.com/).

Questions about this trial

What is this clinical trial studying?

An observational study of COVID-19 and Cancer, run by University of Wisconsin, Madison at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mortality due to COVID-19 (time frame: February 1, 2020, through January 31, 2022). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04506528, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2022.
