CRB-65 v.1
Clinical scoring system used to predict severity of community-acquired pneumonia, measured in 30-day mortality. CRB-65 is an acronym for Confusion, Respiratory rate, Blood pressure and age (over or equal to) 65. Patients scoring one point or higher should be considered for hospital admission.
To assess severity of community-acquired pneumonia measured in 30-day mortality, and aid in determining care level.
Use to evaluate the presence of key factors determining severity of illness in patients presenting with suspected community-acquired pneumonia. CRB-65 is an acronym for Confusion, Respiratory rate, Blood pressure and age (over or equal to) 65. When present each factor contributes one (1) additional point to the total score. Total score ranges from 0-4 and is associated with a risk level, which is in turn associated with certain care level recommendations. * 0 points, low risk group. Consider home treatment. 30-day mortality: 1,2 %. * 1-2 points, moderate risk group. Consider hospital admission. 30-day mortality: 8,2 %. * 3-4 points, severe risk group. Urgent hospital admission, consider ICU admission. 30-day mortality: 31,3 %.
Use with caution in community setting as most validation studies are hospital based. Study results show accurate performance in hospital settings and suggest a possible over-prediction in community settings.
