ALB and susceptibility to pneumonia measurement: For example, the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) system, the Pneumonia Severity Score Index (PSI), score based on Confusion, Urea, Respiratory rate, Blood pressure, and age 65 (CURB 65); the Severe Community Acquired Pneumonia (SCAP) score, and the score based on Systolic blood pressure, Multilobar involvement, Albumin, Respiratory rate, Tachycardia, Confusion, Oxygenation, and PH (SMART-COP), which are now widely used to predict clinical outcomes in pneumonia (7–9).
