DISEASE INTERVENTION COMPARISON RESULTS
Ann Emerg Med. 2006 May;47(5):448-54 Cohorts
IN syncope The Use of
San Francisco Syncope Rule (presence of any of: 1) history of heart failure; 2) Hematocrit <30%; 3) abnormal ECG; 4) complaint of dyspnea; and 5 ) systolic blood pressure <90 mmHg
As Prognostic Item
Is useful Than
no comparison here
To rule out patients with a high risk of serious outcome in the following 30 days: sensitivity 98%, specificity 56%, LR+ 2.2, LR- 0.03

To rule out patients with a high risk of serious outcome in the following 7 days: sensitivity 89%, specificity 42%
Ann Emerg Med. 2009 Dec;54(6):769-778.e1-5 Study type to be defined
IN syncope, elder people The Use of
a syncope risk score: 1 point any of: age > 90, male sex, history of arrhythmia, triage systolic blood pressure > 160 mm Hg, abnormal ECG, and abnormal troponin I ; -1 point for near (incomplete) syncope
As Prognostic Item
Is useful Than
no comparison done
To predict risk of serious event at 30 days: 2.5% in low (-1 or 0 points), 3.3% in intermediate (1-2 points) and 20% in high (3-6 points) risk patients
