Is Shock Index a Valid Predictor of Mortality in Emergency Department Patients With Hypertension, Diabetes, High Age, or Receipt of β- or Calcium Channel Blockers?
Shock index is independently associated with 30-day mortality in a broad population of ED patients. Old age, hypertension, and β- or calcium channel blockers weaken this association. However, a shock index greater than or equal to 1 suggests substantial 30-day mortality risk in all ED patients.
Melancholy index of the HDRS>or =1.5 could be a useful clinical tool to detect patients with acute stroke at high risk of developing PSD.
