Addiction Severity Index in a chronic pain sample receiving opioid therapy
Open accessAbstract
The treatment of chronic pain with opioids remains controversial. Physicians are concerned about addiction and drug diversion, and there is limited empirical information on the use of opioids in patients with chronic pain. This report presents data on the Addiction Severity Index (ASI) collected in a sample of patients (N = 908) receiving opioids from their primary care physicians. The ASI provides clinically important information about patients receiving opioid therapy. The ASI consists of seven subscales, including medical, alcohol, drug, employment/support, legal, family/social, and psychiatric domains. Clinically relevant findings include high ASI medical score (0.87), high psychiatric severity score (0.27), lifetime treatment of alcohol problems (reported by 22% of men), prior delirium tremens (5.6%), prior treatment for drug problems (10.1%), prior drug overdose (12.1%), and drunk-driving citations (28%); 40.3% of women had serious suicidal thoughts, and 23.8% had suicide attempts. The ASI provides important information that can help primary care physicians manage patients with chronic pain who are receiving opioid therapy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
