What this trial studies

The study prospectively collects clinical, diagnostic, therapeutic, and laboratory data from adults hospitalized with SARS‑CoV‑2 infection using an eCRF on the REDCap platform. Data are organized in a 'stem and leaf' database structure aligned with WHO pandemic data recommendations, with a core dataset and optional 'leaf' modules for specific protocols. The intent is to describe disease course, identify risk strata for fatal events, and inform real-world therapeutic procedures. Enrollment is limited to patients aged 18 and over with clinical or radiological evidence of COVID‑19 and a positive SARS‑CoV‑2 test at the participating center.

Who should consider this trial

Good fit: Adults (18+) hospitalized with clinical or radiological evidence of lung infection and a laboratory-confirmed positive SARS‑CoV‑2 test are ideal candidates.

Not a fit: Children under 18, non-hospitalized patients, or people without a confirmed positive SARS‑CoV‑2 test are not eligible and would not benefit from this protocol.

Why it matters

Potential benefit: If successful, the data could help clinicians predict which hospitalized patients are at higher risk and refine treatment pathways to reduce complications and deaths.

How similar studies have performed: Numerous observational cohorts worldwide have already described the natural history of hospitalized COVID‑19 patients and contributed to risk stratification, so this approach builds on established methods.
