QUANTIFYING DRUG-SEEKING BEHAVIOR: A CASE CONTROL STUDY

Background: Drug-seeking behavior (DSB) is common in the Emergency Department (ED), yet the literature describing DSB in the ED consists predominantly of anecdotal evidence. Study Objectives: To perform a case-control study examining the relative frequency of DSB in suspected drug-seeking patients as compared to all ED patients. Methods: We performed a retrospective chart review of 152 drug-seeking patients and of age- and gender-matched controls, noting which of the following behaviors were exhibited during a 1-year period: reporting a nonnarcotic allergy, requesting addictive medications by name, requesting a medication refill, reporting lost or stolen medication, three or more ED visits complaining of pain in different body parts, reporting 10 out of 10 pain, reporting > 10 out of 10 pain, three or more ED visits within 7 days, reporting being out of medication, requesting medications parenterally, and presenting with a chief complaint of headache, back pain, or dental pain. Results: The odds ratios for each studied behavior being used by drug seeking patients as compared to controls were: non-narcotic allergy: 3.4, medication by name: 26.3, medication refill: 19.2, lost or stolen medication: 14.1, three or more pain related visits in different parts of the body: 293, 10 out of 10 pain: 13.9, three visits in 7 days: 30.8, out of medication: 26.9, headache: 10.9, back pain: 13.6, and dental pain: 6.3. Zero patients in the control group complained of greater than 10-out-of-10 pain or requested medication parenterally, resulting in a calculated odds ratio of infinity for these two behaviors. Conclusions: Requesting parenteral medication and reporting greater than ten out of ten pain were most predictive of drug-seeking, while reporting a non-narcotic allergy was less predictive of drug-seeking than other behaviors.
