Eyer et al developed nomograms for predicting problems during alcohol withdrawal. One nomogram predicted the chances of delirium tremens. The authors are from Medizinische Klinik of Technische Universitat Munchen.
Patient selection: alcohol withdrawal
Outcome: delirium tremens
Parameters:
(1) serum potassium concentration in mmol/L from 2 to 6 mmol/L
(2) platelet count from 0 to 600*10^9/L
(3) structural brain lesion
points for potassium =
= (-19.6165 * (potassium)) + 117.699
points for platelet count =
= (-0.153846 * (platelet count)) + 100
Structural Brain Lesion(s)
Points
absent
0
present
31.5
total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 210
• The higher the score the greater the risk of delirium tremens.
