International Registry of Healthcare Workers Exposed to COVID-19 Patients (UNITY Global)
- Conditions
- Covid19SARS-CoV Infection

- Other: Comparative Observational Cohort Study
- Registration Number
- NCT04626076
- Lead Sponsor
- Certara
- Brief Summary
The International Registry of Healthcare Workers Exposed to COVID-19 Patients (UNITY Global), is an international registry of approximately 10,000 healthcare workers in low- and middle-income countries experiencing increasing numbers of COVID-19 cases and commensurate increased exposure to the SARS-CoV-2 virus among their healthcare worker populations.
- Detailed Description
The registry will enrol HCWs who are experiencing or are expected to experience ongoing and recurrent close contact with confirmed or clinically diagnosed COVID-19 patients. Recruitment for the registry will aim to enrol a representative distribution of HCWs on the front lines of diagnosing and caring for COVID-19 patients in both hospitals and community settings, as well as a balanced sample of HCWs receiving the most commonly administered putatively prophylactic drug regimens.
The registry will collect information on a weekly basis from HCWs across a 12-week period following their first known exposure to confirmed or clinically diagnosed COVID-19 patients prior to or within 30 days after enrollment. Data collection will include the drug regimens being taken by the HCWs, information about their level of exposure to COVID-19 patients, their personal health status, and other factors such as the use of PPE which would likely impact their risk of developing a SARS-CoV-2 infection.
A standard pharmaco-epidemiological inferential analysis will be conducted treating the registry data as a cohort with dynamic exposure to both prophylactic treatment and to COVID-19 infected patients and adjusting for potential confounding. Crude and adjusted hazards ratios will be estimated for each of the prophylactic regimens of interest and any observed impact on the risk of infection among HCWs based on all statistical inferential models will be reported

- Primary Outcome Measures
Name Time Method Occurrence of SARS-CoV-2 infection among HCWs caring for COVID-19 patients, in terms of time, geography, healthcare setting, type of HCW. 12 weeks Assess the association of potential prophylactic treatments with reduced risk of COVID-19 (or SARS-CoV-2 infection) in HCWs caring for COVID-19 patients
- Secondary Outcome Measures
Name Time Method Occurrence of SARS-CoV-2 uninfected HCWs 12 weeks Subjects reporting "No" clinical diagnosis of COVID-19 or positive test results.
Occurrence of SARS-CoV-2 infection with ambulatory status and no limitation of activities 12 weeks Subjects reporting COVID-19 related symptoms, clinical diagnosis of COVID-19 or positive test results but reporting "No" limitation of activities due to their symptoms and no hospitalization.
Occurrence of SARS-CoV-2 infection with ambulatory status and limitation of activities 12 weeks Subjects reporting COVID-19 symptoms, clinical diagnosis of COVID-19 or positive test results and reporting "Yes" to having their usual activities limited being limited due to their symptoms, but no hospitalization.
Occurrence of hospitalization due to COVID-19 illness with mild disease 12 weeks Subjects being hospitalised without being admitted to the ICU or without ventilation.
Occurrence of hospitalization due to COVID-19 illness with severe disease 12 weeks Subjects being hospitalised with either admittance to the ICU and/or receiving ventilation.
Occurrence of all-cause mortality 12 weeks Assess occurrence of all-cause mortality.
Type of prophylactic treatments by dose, frequency and duration, overall and by country/region/site 12 weeks Assess the association between prophylactic treatments and the risk of SARS-CoV-2 infection in HCWs caring for COVID-19 patients.
