Calc Hct Ci

x402 APIFailing, checked 4 h ago

Sorror 2005 HCT-specific comorbidity index. Seventeen caller-assigned comorbidities with published weights 1, 2, or 3 (max 26). Pulmonary moderate vs severe and hepatic mild vs moderate/severe are mutually exclusive. Risk groups: 0 low, 1–2 intermediate, ≥3 high. Caller supplies the published category; magent does not interpret PFTs or echo and does not list for transplant. Not Charlson. Not a diagnosis. Not a medical device.
