MEWS (classic version, Subbe 2001) is an early warning score that predates NEWS2, still used in several institutions with their own local variants.
Medical notice: Reference and organization tool for healthcare professionals. This is NOT a medical device, does NOT provide a diagnosis, and does NOT replace clinical judgment or current institutional guidelines. The professional using this calculator is responsible for validating every result against current evidence and regulations before applying it to a real patient. Free tool by CESCAC Productos y Servicios S.A.S. (RUC 0993389404001, Ecuador).
Technical note: MEWS has multiple institutional variants with slightly different cut-offs depending on hospital/country. This calculator uses the original article's version (Subbe 2001, QJM). Validate against the MEWS protocol currently in force at your institution.
