Onder et al reported the GerontoNet ADR risk score for estimating the risk of adverse drug reactions (ADR) in a hospitalized geriatric patient. The authors are from multiple institutions in Europe and the data analyzed was from GIFA (Gruppo Italiano di Farmacoepidemiologie nell'Anziano).
Parameters:
(1) number of comorbid conditions
(2) heart failure
(3) liver failure
(4) renal failure
(5) history of an adverse drug reaction (ADR)
(6) number of drugs

ADR risk score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: 0
• maximum score: 10
• The higher the score the greater the risk of having an adverse drug reaction.

Purpose: To identify a geriatric patient in the hospital who is at risk for an adverse drug reaction (ADR) using the GerontoNet ADR risk score.
