The word patient originally meant 'one who suffers'. This English noun comes from the Latin word patiens, the present participle of the deponent verb, patior, meaning 'I am suffering,' and akin to the Greek verb πάσχειν (= paskhein, to suffer) and its cognate noun πάθος (= pathos).
A Diagnosis-Related Group (DRG) is a system used in healthcare to classify and group patients with similar clinical conditions and resource utilization. DRGs are primarily utilized for billing and reimbursement.
