The curb-65 score for pneumonia is mainly for disease assessment, and its clinical indicators include the following: 1, impaired consciousness; 2, blood urea nitrogen >7 mmol/L; 3, respiratory rate ≥30 breaths/min; 4, systolic blood pressure <90 mmHg or diastolic blood pressure ≤60 mmHg; 5, the patient's age ≥65 years. If the patient has a curb-65 score of 0-1, it is recommended that the patient can be treated out-of-hospital. curb-65 score of 2, it is recommended that the patient can be hospitalized for a short period of time. If the patient has a curb-65 score of ≥3, this suggests severe pneumonia, and the patient is recommended to be hospitalized or treated in the ICU. As the curb-65 score increases, the patient's mortality rate increases accordingly.
